What it costs to build an ADU in Saugerties, NY
An 800 sq ft accessory dwelling unit in Saugerties runs roughly $200k–265k, or about $252–330/sq ft, and that per-square-foot figure sits deliberately above the $206–270/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 Saugerties maps 9 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 Saugerties
Standard finish, slab on grade, on a flat and clear part of the lot, general-contractor margin included. These are structure costs at Ulster County pricing, before the service and septic work a second dwelling can trigger.
| Size | Type | $ / sq ft | Estimated total |
|---|---|---|---|
| 400 sq ft | Studio | $334–$438 | $135k–175k |
| 600 sq ft | One bedroom | $280–$366 | $170k–220k |
| 800 sq ft | One bedroom, larger | $252–$330 | $200k–265k |
| 1,000 sq ft | Two bedroom | $236–$309 | $235k–310k |
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 | $17–$23 | $17 | — |
| Framing | $26–$32 | $26 | — |
| Envelope - roof, siding, windows | $32–$41 | $32 | — |
| Plumbing | $28–$34 | $17 | 55% |
| Electrical | $19–$24 | $13 | 35% |
| HVAC | $23–$29 | $15 | 45% |
| Insulation | $7–$9 | $7 | — |
| Interior finishes | $33–$44 | $28 | 15% |
| Millwork & cabinetry | $19–$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 Saugerties 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.

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 Central Hudson 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 rentalsShort-term rentals allowed with registration. Renting a home short term needs an operating permit from the town building department, under Local Law No. 2 of 2022, which is Chapter 194 of the code. Separate question from whether you can build the unit.

ADU cost in Saugerties: common questions
How much does it cost to build an ADU in Saugerties, NY?
An 800 sq ft accessory dwelling unit in Town of Saugerties runs roughly $200k–265k at a standard finish, general-contractor margin included. A 400 sq ft studio runs about $135k–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 Saugerties?
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 $252–330/sq ft against $206–270/sq ft for a full house, even though it is the same trades doing the same work.
Are ADUs allowed in Saugerties?
Town of Saugerties has 9 districts. 8 districts allow ADUs, 1 does not. Check the specific address with the free ADU checker or confirm with the building department at (845) 246-2800 before you spend money on design.
Can I rent an ADU in Saugerties short term?
Short-term rentals allowed with registration for Town of Saugerties. 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.
