Wheatland · ADU cost
What it costs to build an ADU in Wheatland, NY
An 800 sq ft accessory dwelling unit in Wheatland runs roughly $200k–260k, or about $249–327/sq ft, and that per-square-foot figure sits deliberately above the $204–268/sq ft a full house costs here. An ADU still needs one whole kitchen, one whole bath, its own service panel and its own heating plant no matter how small you draw it, and those costs do not shrink with the floor plan, so they land on half the square footage and push the rate up. Whether the town will let you build one is a separate question from what it costs, and it gets answered parcel by parcel rather than townwide, since the Town of Wheatland maps 5 districts that treat accessory units differently from one another, so read the table below as a starting point rather than a verdict.
ADU cost by size in Wheatland
Standard finish, slab on grade, on a flat and clear part of the lot, general-contractor margin included. These are structure costs at Monroe County pricing, before the service and septic work a second dwelling can trigger.
| Size | Type | $ / sq ft | Estimated total |
|---|---|---|---|
| 400 sq ft | Studio | $331–$433 | $130k–175k |
| 600 sq ft | One bedroom | $276–$362 | $165k–215k |
| 800 sq ft | One bedroom, larger | $249–$327 | $200k–260k |
| 1,000 sq ft | Two bedroom | $233–$305 | $235k–305k |
400 sq ft — One room plus a bath. Garage conversions and small backyard cottages land here.
600 sq ft — The most common detached build - a real bedroom, full kitchen, one bath.
800 sq ft — Room for a proper living area. Still a single bath and one kitchen.
1,000 sq ft — About as large as most codes allow an accessory unit to go.
Why the rate is higher than a house
The systems below are priced for an 800 sq ft unit. The middle column is what each system would cost if it simply shrank with the floor plan; the left column is what it actually costs once you account for the equipment a dwelling needs one of regardless of size. The gap between the two columns is the whole reason small builds price the way they do.
| System | $ / sq ft in an ADU | If it scaled with floor area | Fixed per unit |
|---|---|---|---|
| Site work | $7–$11 | $7 | — |
| Foundation | $16–$23 | $16 | — |
| Framing | $25–$32 | $25 | — |
| Envelope - roof, siding, windows | $32–$41 | $32 | — |
| Plumbing | $28–$34 | $16 | 55% |
| Electrical | $18–$24 | $13 | 35% |
| HVAC | $23–$28 | $15 | 45% |
| Insulation | $7–$9 | $7 | — |
| Interior finishes | $32–$43 | $27 | 15% |
| Millwork & cabinetry | $18–$28 | $11 | 55% |
The fixed-per-unit share is a modeling assumption, not a figure from the code: it is our estimate of how much of each system's budget buys equipment a dwelling needs exactly one of - a kitchen rough-in, a bath group, a service panel, a heating plant - and therefore does not shrink when the unit does. Site work, foundation, framing, envelope and insulation are treated as scaling straight with floor area, which understates the premium slightly, because a small building carries more envelope per square foot of floor than a large one.
What the Wheatland code says about accessory units
Whether you can build one, and how large, is decided by the district your parcel sits in rather than by the town as a whole. The table shows how each mapped district treats ADUs alongside the lot and setback standards a second unit still has to fit inside. District boundaries and conditions vary, so treat it as a starting point and confirm the district that applies to your parcel.
| District | Min lot | Setbacks F / S / R | Max height | ADU |
|---|---|---|---|---|
| Agricultural Residential 2 (AR-2) — the town's principal rural district and the only one whose standards do not collapse under a septic requirement. 2 ACRES with 200 ft of lot width WITHOUT PUBLIC WATER, dropping to 50,000 sf (1.15 acres) with 175 ft of width WITH PUBLIC WATER. The recorded 2 acres and 200 ft are the unserviced case, which matches the district's own name and is the conservative reading; the serviced figures are a genuine alternative and roughly 57% of Wheatland's residential parcels do have public water, so the 50,000 sf tier is available on much of the town and should be checked parcel by parcel rather than assumed away. AR-2 IS THE ONLY DISTRICT IN WHEATLAND WHOSE MAXIMUM LOT COVERAGE MOVES WITH SERVICING, AND THE SWING IS 2x: 10% without public water and 20% with. The recorded 10 is the unserviced figure, consistent with the recorded 2-acre lot; a parcel on public water gets both a smaller minimum lot and double the coverage allowance, so the two figures must be read as a matched pair and never mixed. On the 2-acre minimum a 10% cap is about 8,712 sf of building, which is generous; on a 50,000 sf serviced lot a 20% cap is about 10,000 sf. Front yard 75 ft, side yard 25 ft minimum for one side, maximum height 2 1/2 stories or 35 feet. AR-2's front and side yards are the deepest of any residence district here — R-24 and R-16 take 50 ft fronts and R-12 just 35 ft — so the step down from AR-2 is a change of character rather than only of lot size. Note that Wheatland states its coverage as 'percent of total area occupied by MAIN AND ACCESSORY BUILDINGS', so a detached garage or barn consumes the allowance; it is a building-coverage figure and not an impervious-surface cap, unlike Hamlin's. | 2 ac | 75 / 25 / 40 ft | 35 ft | No |
| Residence 24 (R-24) — nominally a 24,000 sf district, and the recorded 40,000 sf (0.92 acres) is NOT an error: § 130-11 gives 24,000 sf only 'with public sewer AND public water', 40,000 sf 'with public water and Health Department approval of a septic system', and marks the district NOT ALLOWED where there is neither public sewer nor public water. THE SEPTIC FIGURE IS THE ONE THAT GOVERNS MOST OF THE TOWN AND THIS IS EVIDENCED: a 901-parcel residential sample from the Monroe County parcel layer (SWIS 265689) returned 795 on PRIVATE SEPTIC against 89 on public sewer, with 513 on public water against 375 private. So the common Wheatland parcel is water-plus-septic, which lands in the 40,000 sf row — the district's own name understates the land required by 67% on the typical lot. Anyone quoting '24,000 square feet' for R-24 without first establishing that the parcel has public sewer will be wrong on the great majority of sites. THE SEPTIC REQUIREMENT ALSO COLLAPSES TWO DISTRICTS INTO ONE: R-16's septic figure is likewise 40,000 sf, so on septic R-24 and R-16 are dimensionally identical in lot area and differ only in width (120 vs 100 ft) and side yard (15 vs 12 ft). The nominal 24,000/16,000 distinction exists only where public sewer is available. Lot width 120 ft, front yard 50 ft, side yard 15 ft minimum for one, maximum lot coverage 25% counting MAIN AND ACCESSORY BUILDINGS, height 2 1/2 stories or 35 feet. Note that R-24 being 'not allowed' without public water at all is a genuine prohibition rather than a large-lot alternative — an unserviced parcel cannot be developed in this district on any lot size. | 0.9182 ac | 50 / 15 / 35 ft | 35 ft | No |
| Residence 16 (R-16) — nominally a 16,000 sf district, and the recorded 40,000 sf (0.92 acres) is deliberate: § 130-11 gives 16,000 sf only 'with public sewer AND public water' and 40,000 sf 'with public water and Health Department approval of a septic system'. THE GAP HERE IS THE LARGEST IN THE TOWN — 2.5x — AND IT IS THE SINGLE MOST MISLEADING NUMBER IN WHEATLAND'S CODE. Because roughly 88% of the town's residential parcels are on private septic (795 of 901 sampled from the county parcel layer at SWIS 265689), the 40,000 sf figure is the normal case and the district name describes a minority condition confined to the sewered area near the Village of Scottsville. ON SEPTIC, R-16 AND R-24 REQUIRE EXACTLY THE SAME 40,000 SF, so the nominal step between the two districts disappears entirely and what remains is a 100 ft versus 120 ft width and a 12 ft versus 15 ft side yard. Underwriting an R-16 parcel from its name would overstate yield by two and a half times. Lot width 100 ft, front yard 50 ft, side yard 12 ft minimum for one, maximum lot coverage 25% counting main AND accessory buildings, height 2 1/2 stories or 35 feet. Like R-24, R-16 is NOT ALLOWED where there is neither public sewer nor public water, so public water is a precondition for the district in any configuration. | 0.9182 ac | 50 / 12 / 35 ft | 35 ft | No |
| Residence 12 (R-12) — Wheatland's densest single-family district. Nominally 12,000 sf, and the recorded 20,000 sf (0.46 acres) is the 'with public water and Health Department approval of a septic system' figure, which the parcel evidence makes the common case: 795 of 901 sampled residential parcels in the town are on private septic. With public sewer AND public water the minimum drops to 12,000 sf; without public water the district is not allowed at all. The septic penalty here is 67%, the same proportion as R-24 but from a smaller base. Lot width 80 ft — the narrowest in the town — front yard 35 ft, side yard 10 ft minimum for one, height 2 1/2 stories or 35 feet. R-12 CARRIES THE HIGHEST LOT COVERAGE IN WHEATLAND AT 30%, against 25% in R-24, R-16 and RA and 10% in unserviced AR-2, and that figure counts MAIN AND ACCESSORY BUILDINGS TOGETHER — so on a 20,000 sf septic lot the total building footprint including any detached garage is capped at about 6,000 sf. Note the shallow 35 ft front yard: combined with an 80 ft width this is the one district in Wheatland whose envelope resembles a conventional suburban subdivision rather than a rural one, but the septic requirement means most R-12 lots are nonetheless nearly half an acre. | 0.4591 ac | 35 / 10 / 30 ft | 35 ft | No |
| Residence A (RA) — Wheatland's only multi-family district and the only route to more than one dwelling on a lot anywhere in the town. minLotSize IS NULL BY DESIGN because RA is governed by a per-unit density: § 130-11 sets a MINIMUM LOT AREA PER DWELLING UNIT OF 3,500 SQUARE FEET, the smallest per-unit land requirement recorded anywhere in Monroe County, alongside a 12,000 sf minimum for the lot itself. Once the 12,000 sf lot minimum is met, yield runs at roughly 12 units per acre. Recording the 12,000 sf as a lot minimum would imply one dwelling on that land and understate the district's capacity several-fold, which is the error that reached a live public page for Greece's RM and RS districts. RA IS ONLY AVAILABLE WITH FULL PUBLIC SERVICES AND THAT IS THE BINDING CONSTRAINT, NOT THE DENSITY. The district states a lot area in the 'with public sewer and public water' row only and is BLANK in the 'with public water and Health Department approval of a septic system' row — on the structure of § 130-11 that means an RA lot cannot be created on septic at all. Since 795 of 901 sampled residential parcels in the town are on private septic and only 89 on public sewer, RA is confined to the small sewered area around the Village of Scottsville and is not an option across most of Wheatland's land. Lot width 100 ft, front yard 50 ft, SIDE YARD 30 FT MINIMUM FOR ONE — the deepest side yard of any residence district here, deeper even than AR-2's 25 ft, which is the code's way of buffering multi-family form against its neighbours. Maximum lot coverage 25% counting main AND accessory buildings; height 2 1/2 stories or 35 feet, the same cap as every other district, so the density must be found in footprint and unit size rather than in storeys. | — | 50 / 30 / 30 ft | 35 ft | No |
Size limits on record in Wheatland
Where the code states a size cap, it decides which row of the cost table above actually applies to you. These are the caps recorded for Wheatland:
- Agricultural Residential 2 (AR-2) — the town's principal rural district and the only one whose standards do not collapse under a septic requirement. 2 ACRES with 200 ft of lot width WITHOUT PUBLIC WATER, dropping to 50,000 sf (1.15 acres) with 175 ft of width WITH PUBLIC WATER. The recorded 2 acres and 200 ft are the unserviced case, which matches the district's own name and is the conservative reading; the serviced figures are a genuine alternative and roughly 57% of Wheatland's residential parcels do have public water, so the 50,000 sf tier is available on much of the town and should be checked parcel by parcel rather than assumed away. AR-2 IS THE ONLY DISTRICT IN WHEATLAND WHOSE MAXIMUM LOT COVERAGE MOVES WITH SERVICING, AND THE SWING IS 2x: 10% without public water and 20% with. The recorded 10 is the unserviced figure, consistent with the recorded 2-acre lot; a parcel on public water gets both a smaller minimum lot and double the coverage allowance, so the two figures must be read as a matched pair and never mixed. On the 2-acre minimum a 10% cap is about 8,712 sf of building, which is generous; on a 50,000 sf serviced lot a 20% cap is about 10,000 sf. Front yard 75 ft, side yard 25 ft minimum for one side, maximum height 2 1/2 stories or 35 feet. AR-2's front and side yards are the deepest of any residence district here — R-24 and R-16 take 50 ft fronts and R-12 just 35 ft — so the step down from AR-2 is a change of character rather than only of lot size. Note that Wheatland states its coverage as 'percent of total area occupied by MAIN AND ACCESSORY BUILDINGS', so a detached garage or barn consumes the allowance; it is a building-coverage figure and not an impervious-surface cap, unlike Hamlin's.RA is a principal multi-family zone: a minimum lot area PER DWELLING UNIT of 3,500 sq ft, by a wide margin the smallest per-unit requirement in Monroe County
- Residence 24 (R-24) — nominally a 24,000 sf district, and the recorded 40,000 sf (0.92 acres) is NOT an error: § 130-11 gives 24,000 sf only 'with public sewer AND public water', 40,000 sf 'with public water and Health Department approval of a septic system', and marks the district NOT ALLOWED where there is neither public sewer nor public water.

So the common Wheatland parcel is water-plus-septic, which lands in the 40,000 sf row — the district's own name understates the land required by 67% on the typical lot. Anyone quoting '24,000 square feet' for R-24 without first establishing that the parcel has public sewer will be wrong on the great majority of sites. THE SEPTIC REQUIREMENT ALSO COLLAPSES TWO DISTRICTS INTO ONE: R-16's septic figure is likewise 40,000 sf, so on septic R-24 and R-16 are dimensionally identical in lot area and differ only in width (120 vs 100 ft) and side yard (15 vs 12 ft). The nominal 24,000/16,000 distinction exists only where public sewer is available. Lot width 120 ft, front yard 50 ft, side yard 15 ft minimum for one, maximum lot coverage 25% counting MAIN AND ACCESSORY BUILDINGS, height 2 1/2 stories or 35 feet. Note that R-24 being 'not allowed' without public water at all is a genuine prohibition rather than a large-lot alternative — an unserviced parcel cannot be developed in this district on any lot size.RA is a principal multi-family zone: a minimum lot area PER DWELLING UNIT of 3,500 sq ft, by a wide margin the smallest per-unit requirement in Monroe County

Costs an ADU adds that a house does not
- Septic and water A second dwelling adds bedrooms to the design flow, which on an unsewered parcel often means expanding or replacing the existing system rather than tapping it. This is the single most common reason an ADU budget moves after design, and it is site-specific enough that no model should quote it - get it evaluated early.
- Utility service RG&E territory. A detached unit needs power run to it, and whether it goes on its own meter or subfeeds the main house changes both the cost and the permit path.
- Access and parking Many codes require an added parking space for the accessory unit, and a detached unit usually needs a driveway extension or a path, both of which count against a lot-coverage or impervious-surface cap.
- Short-term rentalsNo local short-term-rental law on record - which is not the same as permission. NO SHORT-TERM RENTAL PROVISION EXISTS IN WHEATLAND AND THE FULL SWEEP WAS RUN. Article II Zoning Map; District Regulations (132,853 characters, covering every district and both use tables) returns nothing for 'short-term rental', 'tourist home' or 'bed-and-breakfast' in either hyphenation, and all 33 chapters of the Wheatland Town Code were enumerated from the eCode360 table of contents and swept for a rental, lodging, licensing, registration or occupancy chapter — none exists. That whole-code step is mandatory in this county rather than thorough: Mendon hides a complete STR operating-permit regime in Ch. 208 and Gates in Ch. 148, and a zoning-only search in either returns a confident false negative. Wheatland's negative is therefore a tested one, not an assumed one. WHEATLAND HAS NO COMMERCIAL LODGING USE IN ITS RESIDENCE DISTRICTS AT ALL — no tourist home, no bed-and-breakfast, no hotel — which puts it with Riga at the restrictive end of the county and apart from Mendon (tourist homes and B&Bs by special permit in two districts) and Rush (boutique hotels and B&Bs, but on a commercial list). ABSENCE IS NOT PERMISSION: the Floodplain and Residence Districts are governed by a Table of Use Regulations at § 130-10, which is a closed enumeration, so an unlisted whole-house short-term rental is not authorised by silence. strStatus is 'unknown' rather than 'prohibited' because that reading has not been confirmed with the Town. New York State's 2025 statewide short-term rental registry (Ch. 99 of the Laws of 2025) obliges every host to register regardless of local law. Confirm with Code Enforcement at (585) 889-1553.

ADU cost in Wheatland: common questions
How much does it cost to build an ADU in Wheatland, NY?
An 800 sq ft accessory dwelling unit in Town of Wheatland runs roughly $200k–260k at a standard finish, general-contractor margin included. A 400 sq ft studio runs about $130k–175k. Those are structure costs on an easy site and do not include the septic, water or electrical service work a second unit often triggers.
Why does an ADU cost more per square foot than a house in Wheatland?
Because a lot of a dwelling's cost is per dwelling, not per square foot. One kitchen, one bath group, one service panel and one heating plant cost about the same in an 800 sq ft cottage as in a 1,800 sq ft house, so on the smaller unit they get spread over less than half the floor area. That is why an ADU here prices at $249–327/sq ft against $204–268/sq ft for a full house, even though it is the same trades doing the same work.
Are ADUs allowed in Wheatland?
Town of Wheatland has 5 districts. All districts prohibit ADUs. Check the specific address with the free ADU checker or confirm with the building department at (585) 889-1553 before you spend money on design.
Can I rent an ADU in Wheatland short term?
No local short-term-rental law on record - which is not the same as permission for Town of Wheatland. ADU rules and short-term-rental rules are set separately, so a unit you are allowed to build is not automatically one you are allowed to rent nightly. Confirm both before you underwrite the build on short-term-rental income.
ADU costs are modeled estimates in current 2026 dollars at the Monroe County regional index, general-contractor margin included, derived from Offsite's cost engine with a stated adjustment for the equipment a dwelling needs one of regardless of size. They are planning numbers for decision-support only - not a bid, quote, or guarantee, and not legal, architectural or engineering advice. They cover the structure and exclude septic expansion, utility service runs, site work beyond a flat and clear pad, and permit fees. ADU eligibility, size, owner-occupancy and permit conditions in the Town of Wheatland vary by district and often carry exceptions this page does not show; zoning last reviewed 2026-08-13; verify with the building department at (585) 889-1553 before relying on any answer.
