West Jordan ADU Builders: 2026 Rules, Costs & How to Check Feasibility First
Yes — West Jordan allows one accessory dwelling unit (ADU) per qualifying single-family property: an internal unit like a basement apartment, or a detached backyard unit on a platted lot of 10,000+ square feet in an eligible zone. Best fit: owners of detached single-family homes on city sewer. Not eligible: multifamily buildings, mobile homes, and attached housing — townhomes and attached condos. Expect permits, one added parking space, and budgets that commonly run from roughly $60K (basement conversion) to $400K+ (detached build) — labeled planning estimates, not quotes.
The rules decide the project before any contractor does. Below: West Jordan's current requirements, realistic cost drivers, and how to compare West Jordan ADU builders once you know what your lot supports.
Internal vs. detached at a glance
An internal ADU is a self-contained apartment inside your existing home — most often a basement apartment or mother-in-law suite. A detached ADU (the city now calls these DADUs; older documents say "external ADU") is a separate backyard structure on a permanent foundation.
| Question | Internal ADU | Detached ADU (DADU) |
|---|---|---|
| Where does it go? | Inside the existing home (or an addition — see below) | Separate structure, behind or beside the house |
| Minimum lot size | No separate lot-size rule beyond your zone | Platted lot of 10,000+ sq ft in an eligible zone |
| Eligibility | Qualifying detached single-family homes in residential areas (state framework plus city conditions) | R-1, RR, RE, PC, LSFR, VLSFR zones |
| Extra parking | One added paved 9′×18′ off-street space | Same |
| Separate utility meters | Prohibited | May be allowed with utility-provider approval |
| Biggest early risks | Egress, layout, parking, hidden renovation scope | Lot geometry, setbacks, utility runs, design review |
| Typical budget (planning estimate) | ~$60K–$180K | ~$150K–$400K+ |
Rules summarized from West Jordan Ordinance 26-18 and the city's current ADU application. Full details, sources, and the fine print are below.

Can I build an ADU on my West Jordan property?
Probably, if you own a detached single-family home — but a handful of hard stops knock properties out early. West Jordan allows exactly one ADU per property (internal or detached, never both), and the ordinance bars ADUs with multifamily dwellings, mobile homes, and any form of attached housing. The smart move is to screen the dealbreakers before spending a dime on design.
Run your property through this first-pass screen:
| Your situation | What it likely means | What to check next |
|---|---|---|
| Detached single-family home with a usable basement | Internal ADU path is plausible | Egress windows, ceiling height, layout, parking |
| Platted lot of 10,000+ sq ft in R-1, RR, RE, PC, LSFR, or VLSFR | Detached path may be on the table | Setbacks, yard coverage, utility routes, plat restrictions |
| Townhome, attached condo, duplex/multifamily, or mobile home | Not eligible under current city rules — the ordinance bars ADUs with attached housing, multifamily, and mobile homes | Consider whether a future move changes the picture |
| There's already an ADU on the property | A second one isn't allowed | Confirm the existing unit's permit status |
| Property is served by a septic tank | Eligibility is genuinely unclear (see below) | Get project-specific verification before any design spend |
| Your required garage would become the ADU | Conversion may be blocked without a replacement garage | Parking math first — details below |
| Lot sits in a planned community or has a development agreement | Extra plat-level rules may apply | Pull the recorded plat and any HOA/development documents |
A few definitions before we go deeper: a platted lot is a lot created and recorded on an official subdivision plat — the city measures the 10,000 sq ft threshold from the plat, not your fence line. A setback is the minimum required distance between a structure and a property line or another building. Owner occupancy rules govern whether the owner must live on the property to rent a unit.
Which type of ADU makes the most sense in West Jordan?
On constrained lots, the internal ADU usually wins, because the 10,000 sq ft threshold only applies to detached units. A detached unit buys privacy and separation at the cost of a stricter site screen — setbacks, yard-coverage limits, design review, and utility trenching. Garage conversions look easy and often aren't, thanks to a parking rule most homeowners don't see coming.
Basement or internal ADU
The classic Utah ADU — and because you're converting space you already own, it's generally the lowest-cost path per square foot when the space cooperates. The city's application checklist previews what inspectors verify: interconnected smoke alarms in every bedroom, a smoke/CO alarm in the hallway, a water heater strapped to the wall, separation from the rest of the home with at least ½-inch sheetrock and a door, and proof that the basement finish itself was permitted — and the packet warns that this list is a baseline, with additional items possible after on-site inspection. Beyond the checklist, the ordinance requires the unit to have its own eating, sleeping, and sanitation areas separate from the main home; city planning materials describe internal units as having their own access to the outside, so plan on a separate entrance; and bedrooms will need code-compliant egress (emergency-escape) windows under the residential building code. Basements finished under older codes usually need real upgrades to meet today's requirements — budget for discovery, not just drywall.More on basement and internal ADUs →
Detached backyard ADU (DADU)
Maximum privacy and design freedom, and the strongest fit for long-term family housing or rental separation. In exchange: the lot must be a platted 10,000+ sq ft in an eligible zone, the structure needs a permanent foundation, its footprint must stay smaller than the house, it can cover no more than 20% of the rear and side yard, and its design and materials must be compatible with your home and approved by the city's Design Review Committee. Utility runs — trenching water, sewer, power, and possibly gas across your yard — can be the biggest hidden cost driver on the whole project.More on detached ADUs →
Garage conversion
Here's the rule that catches garage-conversion plans off guard: if your attached garage was required and approved as part of the home, you can't convert it to an ADU unless the required two-car garage — or the converted portion of it — is replaced on the property, meeting all city code requirements. Building a replacement garage can cost enough that a purpose-built detached ADU pencils out better. It's still a legitimate path on the right lot; it's just rarely the shortcut it looks like. Detached garages and shops get interesting after October 1, 2026 — more on that below.More on garage conversions →
The addition-with-internal-ADU path
Less known but written directly into city code: if you submit a building-permit application for an addition to your home at the same time as the rental business-license application for an internal ADU, the city treats your home's footprint as the new, larger footprint. Translation — you can expand the house and carve the internal ADU out of the expanded space, rather than being limited to the existing walls. Some marketers call this an "attached ADU"; in West Jordan it's really an internal ADU inside a bigger primary dwelling.
| Type | Strongest fit | Main West Jordan constraint | Biggest early unknown |
|---|---|---|---|
| Basement / internal | Existing usable space, tighter budgets | Egress, separation, parking | Hidden renovation scope |
| Addition + internal ADU | Home can grow; lot can't host a DADU | Coordinated permit + license applications | Structural tie-in and utility scope |
| Detached (DADU) | 10,000+ sq ft lot, privacy priority | Zone, setbacks, coverage, design review | Site work and utility runs |
| Garage conversion | Garage isn't required, or replacement pencils | Required-garage replacement rule | Replacement-garage cost |
What are West Jordan's ADU rules in 2026?
West Jordan rewrote its ADU ordinance in March 2026 (Ordinance 26-18), and it's now one of the clearer rulebooks in the Salt Lake Valley — but it doesn't perfectly match the city's own application packet on every point. The table below reflects the adopted ordinance and the current application. Where the documents disagree, we say so instead of pretending they don't.
| Rule | What it says | Source |
|---|---|---|
| How many ADUs | One per property — internal or detached, never both | Ord. 26-18 §A.2 |
| Eligible properties | Detached single-family only; no multifamily, mobile homes, or any form of attached housing | Ord. 26-18 §A.7 |
| Septic | Prohibited if the primary home is served by a septic tank (see conflict note below) | Ord. 26-18 §A.3 |
| Parking | One additional off-street 9′×18′ space, paved in asphalt or concrete; can't be tandem with or obstruct the home's required parking | Ord. 26-18 §A.5 |
| Required garage | The home must keep its minimum parking, including the two-car garage where applicable; a required attached garage can't convert to an ADU unless replaced per code | Ord. 26-18 §A.6 |
| Renting — license | A proper business license is required to rent the home or the ADU | Ord. 26-18 §A.4 |
| Renting — configuration | Live in one unit → you may rent the other. Live in neither → you may rent both as a single unit, or rent just one — but not both separately to different tenants | Ord. 26-18 §A.4 |
| Rental duration | Short-term stays (nightly/weekly, Airbnb-style) are not permitted; rentals must run at least 30 consecutive days (see the FAQ note on the exact 30-day boundary) | City ADU application |
| Occupancy | One family, or up to 5 unrelated adults sharing the unit as a single household; no subleasing | City ADU application |
| Utility meters | Internal ADUs: separate meters prohibited. Detached ADUs: may be allowed with utility-provider approval, subject to connection/capacity charges (see conflict note) | Ord. 26-18 §A.11 |
| Title notice | A notice may be recorded on the property's title; the current application requires a notarized acknowledgement recorded with the Salt Lake County Recorder before approval, running with the land and consenting to city inspection of the unit | Ord. 26-18 §A.12; city application |
| Detached — lot & zones | Platted lots of 10,000+ sq ft in R-1, RR, RE, PC, LSFR, VLSFR (agricultural zones: see conflict note) | Ord. 26-18 §C.1 |
| Detached — size & siting | Permanent foundation; footprint smaller than the house; max 20% of rear and side yard; not in the front yard (per the application); subject to overall lot-coverage limits | Ord. 26-18 §C.3–5, 8; application |
| Detached — setbacks & height | 6′ from the house, 6′ rear, 6′ interior side, 20′ corner side; 20′ max height; anything over 17′ adds +1′ of side/rear setback per foot of extra height | Ord. 26-18 §C.6 |
| Detached — design | Materials and design must be similar/compatible with the home and approved by the Design Review Committee | Ord. 26-18 §C.7 |

Parking: the rule that quietly kills ADU plans
Every ADU needs one additional paved off-street space, at least 9 feet by 18 feet, in asphalt or concrete — gravel doesn't count. Per the city's application, the space must sit beside the existing driveway, beside the house, or in the backyard; the driveway leading to your garage doesn't count, at least two spaces must remain intact in the garage or carport, and total paving can't exceed 50% of the required front yard.
How that plays out on three common West Jordan setups:
- Two-car garage + standard driveway: the driveway in front of the garage doesn't qualify (parking there blocks the garage). You'll need new paved parking elsewhere on the lot.
- Three-car garage: the third bay can serve as the ADU space, since using it doesn't block the two required spaces.
- Two-car garage + extra-wide driveway: the extra width can qualify — as long as a car parked there doesn't block the garage bays.
Solve parking before you sketch a floor plan. If parking doesn't work, nothing else matters.
Where the city's own documents don't fully match
We found four points where West Jordan's March 2026 ordinance and its other published materials aren't in sync. Rather than quietly pick the version that sells best, here's the honest read:
- 1Septic. The adopted ordinance prohibits ADUs where the primary home is served by a septic tank — period. The application packet (and the state internal-ADU statute's list of allowed restrictions) uses narrower failing septic-tank language. If your property is on septic, treat ADU eligibility as unresolved until it's verified for your specific project. Don't buy plans on either assumption.
- 2Meters. The ordinance splits the rule — internal prohibited, detached possibly allowed with utility approval and connection/capacity charges — while the application still carries older blanket no-separate-meters language. Confirm your metering plan project-specifically before you lock in rental pricing or utility assumptions.
- 3Title recording. The ordinance says a notice may be recorded; the application requires a recorded, notarized acknowledgement before approval. Follow whatever the current application packet instructs when you actually apply.
- 4Agricultural zones. The 2026 ordinance says detached ADUs are permitted "only" in six residential zones, while separate 2022 provisions in the city's agricultural chapter still address ADUs in A-1, A-5, and A-20. Until the codification is visibly harmonized, large-lot and rural parcels need parcel-specific verification rather than a zone-name answer.
City documents get harmonized over time. Until they are, a page that pretends they already agree isn't doing you a favor.
What changes for West Jordan ADUs on October 1, 2026?
Utah's 2026 legislature passed SB 284, creating Utah Code §10-21-304 — effective October 1, 2026 — which requires Utah's larger cities (the statute's "specified municipalities," a class that includes West Jordan) to permit a detached ADU on any lot or parcel of 11,000+ square feet that contains a single-family home, where that home is a permitted use. West Jordan didn't wait for the deadline: Ordinance 26-18 already cites §10-21-304 directly. And the comparison is more interesting than one number: the city's lot-size threshold (10,000 sq ft) is lower than the state's 11,000 sq ft floor, but the city rule requires a platted lot in six listed zones, while the state standard reaches any qualifying lot or parcel. So on October 1, some properties outside the city's current zone-and-plat list may gain a path they don't have today.
| Topic | West Jordan today (Ord. 26-18) | State floor from Oct 1, 2026 (§10-21-304, specified municipalities incl. West Jordan) |
|---|---|---|
| Detached ADU lot minimum | 10,000 sq ft platted lot, six listed zones | Must be permitted on any lot or parcel of 11,000+ sq ft containing a single-family home that is a permitted use there |
| Permit type | Permitted use in listed zones | Cities can't require a conditional use permit in primarily residential zones |
| Parking cap | One added space required | Cities can't require more than 1 space for units under 650 sq ft, or more than 2 spaces at 650+ sq ft |
| Converting existing outbuildings | No dedicated pathway | Cities must offer a process to convert a legally built accessory structure into a detached ADU, subject to setbacks and building/health/fire codes |
| What cities may still require | Owner-occupancy structure, design compatibility, size/height/coverage limits, setbacks, no front-yard placement, one ADU per lot, utility-capacity requirements | Expressly preserved |
| Short-term rental | 30-day minimum (city application) | Cities may prohibit detached-ADU rentals under 90 consecutive days |
| Development agreements | — | Detached-ADU restrictions in development agreements signed on or before May 6, 2026 remain enforceable |
The sleeper opportunity: converting a shop or detached garage
Starting October 1, West Jordan's rules must include a pathway for converting a legally constructed accessory structure — a shop, a detached garage — into a detached ADU, subject to setbacks and building, health, and fire codes. If you have a solid outbuilding, that's a genuinely new door opening this fall. Temper the excitement with two realities: a required attached garage still triggers the replacement rule above, and converting any outbuilding to habitable space usually means significant utility, insulation, and egress work.
One caution: West Jordan may adopt further amendments as the state law takes effect. We re-verify this page after October 1, 2026 — the "last verified" date at the top tells you where things stand.
How much does an ADU cost in West Jordan? (2026 estimates)
There's no single honest "West Jordan ADU price." The ranges below are broad planning estimates that mirror the bands we maintain on our statewide Utah ADU cost guide — West Jordan's construction market doesn't differ materially from the rest of the Salt Lake Valley — assuming a city-sewer lot, workable site access, and mid-grade finishes. They are intentionally wide, they are not quotes, and your lot can move the number substantially in either direction.
| Project type | Typical size | Estimated project range* | What usually drives it up |
|---|---|---|---|
| Basement conversion (internal) | 600–1,000 sq ft | ~$60K–$150K | Egress cuts, low ceilings, moisture, dated systems |
| Other internal conversion / addition + ADU | 400–800 sq ft | ~$80K–$180K+ | Structural tie-in, layout changes, added foundation |
| Detached new build (DADU) | 400–1,000 sq ft | ~$150K–$400K+ | Utility trenching, site access, design review, finishes |
| Prefab/modular detached, installed | 400–800 sq ft | ~$130K–$250K | Foundation, craning/access, utility connections |
*Planning estimates covering design, engineering, permits, and construction under the stated assumptions; they exclude major utility upgrades, replacement garages, and financing costs. A plan-based or prefab unit still requires local engineering, a permanent foundation, utility design, and full West Jordan review — "prefab" never means "permit-free."
The three buckets every complete budget needs
- 1Design and engineering. Architectural plans, structural engineering, mechanical sizing (Manual J & D), energy compliance (REScheck), and — for detached units — a gas-line sizing diagram. Cheap plans are how projects end up paying twice.
- 2City fees. Building-permit fees are calculated from project valuation, with plan review, Design Review Committee fees (detached), and a rental business license on top. One bright-line rule worth knowing: Utah's Impact Fees Act bars cities from charging an impact fee on construction of an internal ADU (Utah Code §11-36a-202). An impact fee is a one-time charge cities assess on new development for infrastructure like parks, water, sewer, and roads — and it's legally distinct from permit fees and from the connection or capacity charges the 2026 ordinance mentions for new detached-ADU meters. For detached units, whether impact fees apply depends on classification; verify the current adopted fee schedule before finalizing a budget rather than trusting any fixed number you read online — including here.
- 3Construction. The bulk of the spend, and the part where "what's excluded" matters more than the headline price.
Costs that early quotes can quietly leave out
Utility capacity or routing (a utility hookup — connecting the unit to water, sewer, power, and gas — can be trivial or brutal depending on distance and what's in the way) · main electrical-panel upgrades · sewer lateral work · the required paved parking space · a replacement garage, if the conversion rule applies · survey and, on some detached sites, geotechnical work · landscaping restoration after equipment tears up the yard · a likely property-tax increase once the county assessor values the new improvement · homeowner's-insurance changes to cover the added structure and any rental use — talk to your carrier.
A property-specific cost path beats a generic range every time.
What does the West Jordan ADU permit process involve?
No West Jordan ADU is legal without permits, and the fastest route through review is a complete submittal the first time. When you budget time, think in months — and for a detached build, closer to a year — not because anyone can promise those numbers, but because design, engineering, city review, corrections, utility work, and inspections stack up, and underestimating the calendar is how homeowners get rushed into bad decisions. No fixed schedule exists until your complete application has been reviewed.
The practical sequence:
- Screen the property. Zone, platted lot size, parking, garage status, sewer vs. septic, easements, and any planned-community or HOA documents.
- Complete the ADU application. The current packet must be filled out by the owner, signed, and notarized; the acknowledgement is recorded with the Salt Lake County Recorder before approval and runs with the land.
- Design and engineer. The city's detached-ADU checklist requires full architectural drawings and engineered drawings with structural calculations — which licensed design professionals your project needs depends on its scope and Utah law; many homeowners pair a residential designer with a structural engineer, and internal projects are often simpler.
- Assemble the building-permit packet. For detached units, the city's published checklist calls for a site plan (showing the ADU, the parking stall, property-line distances, and all utility runs from the house), full architectural drawings, engineered drawings with structural calculations, Manual D & J mechanical documentation, REScheck energy compliance, and a gas-line drawing with pipe sizing and BTU demands. Incomplete packets are rejected outright — review doesn't start until everything's in. Internal-ADU submittals are simpler; the current city checklist and your project scope control.
- City review. Plan check for code compliance, plus Design Review Committee approval of exterior materials and design for detached units (separate fees and review time). The checklist exists precisely because certain items are easy to get wrong — gas-line diagrams, Manual D & J calculations, setback dimensions, and properly documented parking — and a submittal missing any of them stalls before review begins.
- Build and inspect. Foundation, framing, electrical, plumbing, mechanical, insulation, and final inspections as required.
- License before renting. If you'll rent either unit, obtain the rental business license — and don't put a tenant in before final approvals.
How should I compare West Jordan ADU builders?
Compare scope, not sticker price. A bid that's $40K lower because it excludes utility trenching, the parking pad, engineering, and permit handling isn't cheaper — it's incomplete. Directories will show you dozens of general contractors under the "ADU" label; your job is to find the few who can prove they've handled this city's requirements for your project type.
Verify the license yourself — every time
Look up the exact contracting entity in the Utah Division of Professional Licensing (DOPL) license search: current status, classification, expiration, and any public discipline. Make sure the name on the license matches the name on the contract, and re-check on signing day. Anyone doing work that requires a Utah license should hold the appropriate current credential — no exceptions, no "my buddy's license."
Match the builder to the project type
A great custom-home builder isn't automatically great at threading egress windows into a 1978 basement, and a talented remodeler may have never trenched 90 feet of utilities for a backyard unit. Ask for evidence of comparable work: internal conversions, detached builds, garage projects with replacement parking, tight-site logistics — whatever your path demands.
Make every bid answer the same questions
| Before you compare prices, confirm each bid states… | ✔ |
|---|---|
| Who produces the site plan, architecture, and engineering | |
| Who prepares Manual D & J, REScheck, and the gas-line diagram | |
| Who submits to the city and handles plan-check corrections and design review | |
| Written utility assumptions: panel capacity, sewer path, trenching, meter plan | |
| Whether the paved parking space (and any replacement garage) is in scope | |
| Itemized finish allowances, exclusions, and change-order terms | |
| Payment schedule, price-validity window, and warranty | |
| Current DOPL license verified; insurance certificates provided |
Red flags worth walking away from: a firm price before anyone has seen the site, "you don't really need a permit for this," vague allowances, and reluctance to put exclusions in writing.
A disclosed builder relationship
Utah ADU Builders has a referral partnership with Nest Tiny Homes, a design-build company that publicly lists Salt Lake County — including the West Jordan area — in its service area and builds detached ADUs, garage conversions, and custom garages (relevant if the replacement-garage rule touches your project). Those are the company's published claims, not a city endorsement or an independent guarantee, and a partnership never determines whether Nest — or any builder — is the right fit for your property. As with any contractor, confirm current Utah licensure and insurance directly before signing anything.
Start with feasibility and scope, so the estimates you receive are actually comparable.
What can stop or reshape a West Jordan ADU project?
An ADU is not automatically a smart project just because Utah — and West Jordan — have become more ADU-friendly. The right project depends on your lot, utilities, parking, budget, and how you plan to use it. For some properties, the honest answer is "not yet," or "not this type." Here's what most often changes the answer:
- Parking or a required garage. The blocker to check first — especially for garage conversions.
- Septic. With the city's documents in conflict, a septic property needs project-specific verification before any design spend.
- Utility capacity and routing. A legally buildable project can still be financially unattractive if the panel, sewer lateral, or trench route demands major work.
- Lot geometry vs. setbacks. A 10,000 sq ft lot doesn't guarantee a usable building envelope once the 6′/6′/20′ setbacks, the 20% rear-and-side-yard cap, and height rules are drawn.
- Easements. Yard that looks buildable may sit over a recorded easement where nothing can go.
- HOA, plat, and development-agreement restrictions. Utah law limits how far an association can go in blocking a code-compliant internal ADU and its long-term rental — but that protection doesn't automatically extend to detached structures or exterior changes, and the new state law expressly preserves detached-ADU restrictions in development agreements signed on or before May 6, 2026. Pull your CC&Rs and plat before you design.
- Your rental plan. The owner-occupancy configuration and the 30-day minimum shape what income is actually legal. No rental income, occupancy level, financing approval, or property-value outcome is ever guaranteed.
- Budget reality. A feasible project isn't automatically an affordable one; financing approval is its own process, separate from permitting.
If two or more of these apply to you, that's not a reason to quit — it's the reason to run feasibility first: screen these risks through a West Jordan feasibility review.
What should I prepare before requesting an ADU estimate?
The more your builder has to assume, the less your estimate is worth. Ten minutes of preparation turns a guess into a usable number.
| Bring this | Why it matters |
|---|---|
| Address (and parcel number, if handy) | Starts the zone, plat, and lot-size screen |
| Lot size and any survey or plat you have | Reveals boundaries, easements, and the real building envelope |
| Photos: yard, driveway, garage, basement, access route | Shows parking options, site access, and conversion condition |
| Where your utilities are (panel, meters, sewer cleanout) | The unglamorous question that makes or breaks small projects |
| Garage and driveway dimensions | Tests West Jordan's parking rules early |
| Intended use: family, long-term rental, or both | Drives the owner-occupancy and licensing analysis |
| Target size, bedrooms, and accessibility needs | Makes competing scopes comparable |
| HOA/CC&R or development-agreement documents | Surfaces private restrictions the city won't flag for you |
| A realistic budget band | Keeps the design connected to what you'll actually spend |
Feasibility first, then a cost path, then local builder options where your project and coverage align.
Utah ADU Builders may receive compensation when a homeowner requests estimates or is connected with a local professional. A referral relationship never determines whether a property is feasible, which ADU type fits, or whether a particular builder is right for you. Permit approval, costs, timelines, financing, rental results, and builder availability are not guaranteed.
