What it costs to build an ADU in Edinburg, NY

800 sq ft ≈ $200k–260k $249–327/sq ft 4 districts National Grid

An 800 sq ft accessory dwelling unit in Edinburg 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 Edinburg maps 4 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 Edinburg

Standard finish, slab on grade, on a flat and clear part of the lot, general-contractor margin included. These are structure costs at Saratoga County pricing, before the service and septic work a second dwelling can trigger.

SizeType$ / sq ftEstimated 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 ADUIf it scaled with floor areaFixed 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 Edinburg 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
Lakefront Residential (the Great Sacandaga Lake perimeter, intended as a recreation-oriented residential area of single-family dwellings while protecting the lakefront environment: a 1.3-ACRE minimum lot with 100 ft of road frontage, 100 FT OF SHORELINE LOT WIDTH, 35% maximum lot coverage — the highest in the Town — a 25 ft front yard, 10 ft side and rear yards and 40 ft of height. THE SHORELINE SETBACK IS 50 FT, the shallowest in the Town, but note 5 adds that FOR PARCELS WITH LAKEFRONT THE STRUCTURE SETBACK FROM THE HUDSON RIVER BLACK RIVER REGULATING DISTRICT PROPERTY LINE SHALL BE A MINIMUM OF 10 FEET — and § 3.4(2) defines the boundary of Great Sacandaga Lake as the HRBRRD PROPERTY LINE, not the water. On a Sacandaga parcel the regulating district's line, not the shoreline, is the datum that matters. Setbacks apply to ALL structures — principal, accessory AND temporary.

Low Intensity (residential development and compatible uses at a density consistent with the district's relatively high tolerance: a 3.2-ACRE minimum lot — the APA Low Intensity guideline — with 100 ft of road frontage, 125 ft of shoreline lot width, 25% coverage, 25 ft front, side AND rear setbacks (all three equal), a 75 ft shoreline setback, 40 ft of height and a 750 sq ft minimum principal building.

Rural Use (rural land uses compatible with the district's relatively low resource tolerance, preserving the open space basic to the Town's character, and EXPRESSLY AIMED AT PREVENTING STRIP DEVELOPMENT ALONG MAJOR TRAVEL CORRIDORS 'in order to enhance the aesthetic and economic benefits derived from a park atmosphere along these corridors': an 8.5-ACRE minimum lot — the APA Rural Use guideline — with 100 ft of road frontage, 150 ft of shoreline lot width, 25% coverage, 25 ft front, side and rear setbacks, a 75 ft shoreline setback, 40 ft of height and a 750 sq ft minimum principal building. Uses follow the Low Intensity pattern, with multiple family dwellings, commercial uses, tourist accommodations and tourist attractions as SECONDARY (Class B) uses — and § 6.9's per-unit land rule applies here too, so a multiple-family dwelling needs 8.5 ACRES PER DWELLING UNIT.

Resource Management (protection of delicate physical and biological resources and economic management of forest, agricultural and recreational land: A 42.7-ACRE MINIMUM LOT — the APA Resource Management guideline and the largest single lot requirement in this entire dataset — with 100 ft of road frontage, 200 ft of shoreline lot width, A 10% MAXIMUM LOT COVERAGE, 25 ft front, side and rear setbacks, A 100 FT SHORELINE SETBACK, 40 ft of height and a 750 sq ft minimum principal building. Like Rural Use it exists partly to PREVENT STRIP DEVELOPMENT ALONG MAJOR TRAVEL CORRIDORS, and its purpose clause likewise contemplates residential development 'on substantial acreage OR IN SMALL CLUSTERS on carefully selected and well designed sites' — so the § 13.2 cluster subdivision, preserved by Schedule 1 note 1, is again the intended route rather than the exception. § 6.9's per-unit land rule makes a multiple-family dwelling here require 42.7 ACRES PER UNIT, which is a prohibition written as an arithmetic. NOTE THAT THE SETBACKS DO NOT RISE WITH THE LOT: front, side and rear stay at 25 ft in Low Intensity, Rural Use AND Resource Management alike — this Town rations by LAND AREA AND COVERAGE, not by yard depth, which is the opposite of how the Town of Day next door does it.

ADU cost in Edinburg: common questions

How much does it cost to build an ADU in Edinburg, NY?

An 800 sq ft accessory dwelling unit in Town of Edinburg 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 Edinburg?

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 Edinburg?

Town of Edinburg has 4 districts. All districts prohibit ADUs. Check the specific address with the free ADU checker or confirm with the building department at (518) 863-2034 before you spend money on design.

Can I rent an ADU in Edinburg short term?

No local short-term-rental law on record - which is not the same as permission for Town of Edinburg. 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 Saratoga 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 Edinburg vary by district and often carry exceptions this page does not show; zoning last reviewed 2026-08-03; verify with the building department at (518) 863-2034 before relying on any answer.
