What it costs to build a house in Parma, NY
A standard-finish house in Parma runs about $204–268/sq ft all in, which on a 1,800 sq ft build works out to roughly $370k–480k with general-contractor margin already in it. The part people leave out is what you pay before that, because the smallest conforming residential lot in the Town of Parma is 0.1148 acres and vacant land here carries a median assessed value of $7,714 an acre, so the dirt alone is around $886 and the whole thing lands near $370k–480k. Zoning does bite at the dense end of Parma though, because Waterfront Residential (WR) — the Lake Ontario shoreline district and by far the smallest lot in Parma: 5,000 sf, 50 ft of lot width, 30% coverage, 35 ft height, with the tightest yards in the Town at 20 ft primary street, 10 ft side, 10 ft rear and accessory structures 5 ft from rear and side. This is a 9x smaller minimum lot than AR and RR on the same 35 ft height, and it reflects the pre-existing narrow shoreline lot pattern along the lake rather than a policy of density. A primary street-facing entrance is required. THE DISTRICT CODE IS WR, NOT WF — see the note in `source` about a third-party site that gets this wrong. Note that WR's 20 ft front and 10 ft side yards make it the one Parma district where a conforming house fits comfortably on the district's own minimum lot. Accessory apartment permitted by special use permit under § 165-23. caps coverage at 30% of a 0.1148 acre minimum lot and that leaves about 1,500 sq ft of footprint, so an 1,800 sq ft house in that district has to go up rather than out. The figures below come out of the same cost engine Aldo uses to price a real parcel, broken out by system and by what a harder site adds, so you can see where the money actually goes.
Land plus build: the real number in Parma
Build cost is the half everyone quotes. The other half is the lot, and in the Town of Parma the code will not let you build on less than 0.1148 acres in its most permissive residential district, so that is the smallest ticket into the town.
| Line | Amount |
|---|---|
| Minimum conforming residential lot (0.1148 ac at $7,714/ac) | $886 |
| House, 1,800 sq ft, standard finish, slab on a flat lot | $370k–480k |
| Land and build together | $370k–480k |
Land is roughly 0% of that total in Parma. The per-acre figure is the median assessed full market value of vacant residential land across 370 priced parcels here, which is a proxy for what dirt is worth and not an asking price - road-frontage lots that are ready to build on trade above it, and back land without access trades below.
Cost per square foot by finish level
All in, general-contractor margin included, for a slab-on-grade build on a flat and clear lot. The rate holds steady whether you build 1,200 or 2,500 sq ft, which is why the finish level moves a budget more than the size does.
| Finish level | $ / sq ft | 1,800 sq ft total |
|---|---|---|
| Standard | $204–$268 | $370k–480k |
| Custom | $272–$405 | $490k–730k |
| Luxury | $415–$717 | $745k–1.29M |
Standard — Builder-grade but solid - stock cabinetry, mid-range windows, standard fixtures. What most spec cabins and rental builds run.
Custom — Better envelope, upgraded windows and doors, semi-custom millwork and fixtures. The typical Hudson Valley owner-build.
Luxury — High-performance envelope, custom cabinetry, designer fixtures and specialty finishes. Architect-driven, no stock parts.
Where the money goes
A standard-finish build at Monroe County pricing, broken out by trade as dollars per square foot. Foundation and site work here are the slab and flat-lot baseline, so a harder site stacks on top of them.
| System | $ / sq ft |
|---|---|
| Site work | $7–$11 |
| Foundation | $16–$23 |
| Framing | $25–$32 |
| Envelope - roof, siding, windows | $32–$41 |
| Plumbing | $16–$20 |
| Electrical | $13–$16 |
| HVAC | $15–$18 |
| Insulation | $7–$9 |
| Interior finishes | $27–$36 |
| Millwork & cabinetry | $11–$16 |
What moves the number
The baseline assumes the easy case. Each of these stacks on top, per square foot, at Monroe County pricing:
- Crawlspace instead of slab+$13–20/sq ft
- Full basement instead of slab+$31–49/sq ft
- Moderately sloped or wooded lot+$8.7–16/sq ft
- Steep or ledge-rock site+$22–44/sq ft
- Winter foundation & site work+$2.8–4/sq ft
Whole-project totals
Standard finish, slab on a flat lot, all in and before land. A harder site or a higher finish moves these up.
| Home size | Estimated build cost | With a conforming lot |
|---|---|---|
| 1,200 sq ft | $245k–320k | $245k–320k |
| 1,800 sq ft | $370k–480k | $370k–480k |
| 2,500 sq ft | $510k–670k | $510k–670k |
How much house Parma actually lets you build
Every residential district caps how much of the lot the building can cover. Multiply that cap by the district's minimum lot size and you get the largest footprint the code permits on a conforming lot in the Town of Parma, which runs from about 1,500 sq ft in Waterfront Residential (WR) — the Lake Ontario shoreline district and by far the smallest lot in Parma: 5,000 sf, 50 ft of lot width, 30% coverage, 35 ft height, with the tightest yards in the Town at 20 ft primary street, 10 ft side, 10 ft rear and accessory structures 5 ft from rear and side. This is a 9x smaller minimum lot than AR and RR on the same 35 ft height, and it reflects the pre-existing narrow shoreline lot pattern along the lake rather than a policy of density. A primary street-facing entrance is required. THE DISTRICT CODE IS WR, NOT WF — see the note in `source` about a third-party site that gets this wrong. Note that WR's 20 ft front and 10 ft side yards make it the one Parma district where a conforming house fits comfortably on the district's own minimum lot. Accessory apartment permitted by special use permit under § 165-23. to 8,712 sq ft in Rural Residential (RR) — 1 ACRE, 100 ft of lot width, 20% coverage, 35 ft height, with 60 ft primary street yard, 15 ft side and 50 ft rear, and accessory structures 15 ft from rear and side. SEWER IS THE DEFINING CONSTRAINT AND THE CODE SAYS SO IN THE PURPOSE CLAUSE: RR covers areas with 'limited opportunities for infrastructure connections including public sewers,' so an RR parcel should be assumed to need on-site septic until the county parcel layer's SEWERTYPE field says otherwise, and the acre minimum is doing sanitary work as much as density work. The purpose clause also directs that residential development SHOULD USE CLUSTER DEVELOPMENT to preserve rural character, retain open space and conserve natural resources — Town Law § 278 clustering is the expected form here rather than the exception, which means the per-lot acre is negotiable in a cluster layout while the overall yield is not. Same 1-acre minimum as AR but with far shallower side and front yards (15 ft versus 50 ft side), so RR is materially more buildable than AR on an identically sized lot. Accessory apartment permitted by special use permit under § 165-23.. Worth checking before you assume zoning is what is limiting the house, because in most districts it is the budget that runs out first.
| District | Min lot | Lot coverage | Max footprint | Max height |
|---|---|---|---|---|
| Waterfront Residential (WR) — the Lake Ontario shoreline district and by far the smallest lot in Parma: 5,000 sf, 50 ft of lot width, 30% coverage, 35 ft height, with the tightest yards in the Town at 20 ft primary street, 10 ft side, 10 ft rear and accessory structures 5 ft from rear and side. This is a 9x smaller minimum lot than AR and RR on the same 35 ft height, and it reflects the pre-existing narrow shoreline lot pattern along the lake rather than a policy of density. A primary street-facing entrance is required. THE DISTRICT CODE IS WR, NOT WF — see the note in `source` about a third-party site that gets this wrong. Note that WR's 20 ft front and 10 ft side yards make it the one Parma district where a conforming house fits comfortably on the district's own minimum lot. Accessory apartment permitted by special use permit under § 165-23. | 0.1148 ac | 30% | 1,500 sq ft | 35 ft |
| Multifamily Residential (MR) — 10,000 sf, 75 ft of lot width, 30% coverage, 35 ft height, 30 ft primary street yard, 15 ft side, 15 ft rear, accessory structures 10 ft. MR IS THE ONLY DISTRICT IN PARMA WHERE MULTI-UNIT HOUSING AND TOWNHOMES ARE AVAILABLE AT ALL, both by SPECIAL PERMIT under § 165-55, and it is also the only district permitting a two-unit home by right outside N-MU. The recorded 10,000 sf is the lot minimum, NOT a per-unit figure, and the code sets no units-per-acre cap in this section — so yield on an MR parcel is set by § 165-55's supplemental standards, the 30% coverage cap and the 35 ft height together rather than by a density number, and it must be worked from those three rather than assumed. NOTE A TYPOGRAPHICAL HAZARD IN THE SOURCE: the code renders this figure as '10.000 sf' with a decimal point where a comma belongs, and the Waterfront district does the same with '5.000 sf'. Read them as 10,000 and 5,000; a naive parse would produce 10 sf. Accessory apartment permitted by special use permit under § 165-23. | 0.2296 ac | 30% | 3,000 sq ft | 35 ft |
| Neighborhood Residential (NR) — the suburban district: 20,000 sf (0.46 acre), 100 ft of lot width, 20% coverage, 35 ft height, 40 ft primary street yard, 10 ft side, 25 ft rear, accessory structures 10 ft from rear and side. A primary street-facing entrance is REQUIRED here rather than merely encouraged as in AR and RR — Parma's newer code carries form standards alongside the dimensional ones, and the entrance requirement is a real design constraint on a garage-forward plan. The 20% coverage cap on a 20,000 sf lot allows 4,000 sf of building footprint, so coverage is not the binding constraint on a typical single-family house here; lot width and the 40 ft front yard are. Accessory apartment permitted by special use permit under § 165-23. | 0.4591 ac | 20% | 4,000 sq ft | 35 ft |
| Agricultural Residential (AR) — the Town's agricultural district: 1 ACRE MINIMUM FOR NON-AGRICULTURAL USE (the code states the minimum this way, as a lot area 'for non-agricultural use', so a working farm parcel is not sized by it), 100 ft of lot width, 20% maximum lot coverage, 35 ft height, and the DEEPEST SETBACKS IN THE TOWN — 75 ft primary street yard, 50 ft side and 75 ft rear. Those setbacks, not the acre, are what bind a house on a normal AR lot: 75 ft front plus 75 ft rear consumes 150 ft of depth before any building, and 50 ft on each side consumes 100 ft of a 100 ft minimum width, so a lot built exactly to the district minimum has NO conforming building envelope at all and needs either more width or a variance. Corner lots take a SECONDARY street yard of 75 ft as well. Accessory structures sit 25 ft from rear and side lines. Purpose is active farmland, fallow land, woodland and wetland with low-density residential that supports agricultural operations. Farmworker housing anywhere in the Town takes AR's front, side and rear setbacks regardless of the district it sits in (§ 165-36). Accessory apartment permitted by special use permit under § 165-23. | 1 ac | 20% | 8,712 sq ft | 35 ft |
| Rural Residential (RR) — 1 ACRE, 100 ft of lot width, 20% coverage, 35 ft height, with 60 ft primary street yard, 15 ft side and 50 ft rear, and accessory structures 15 ft from rear and side. SEWER IS THE DEFINING CONSTRAINT AND THE CODE SAYS SO IN THE PURPOSE CLAUSE: RR covers areas with 'limited opportunities for infrastructure connections including public sewers,' so an RR parcel should be assumed to need on-site septic until the county parcel layer's SEWERTYPE field says otherwise, and the acre minimum is doing sanitary work as much as density work. The purpose clause also directs that residential development SHOULD USE CLUSTER DEVELOPMENT to preserve rural character, retain open space and conserve natural resources — Town Law § 278 clustering is the expected form here rather than the exception, which means the per-lot acre is negotiable in a cluster layout while the overall yield is not. Same 1-acre minimum as AR but with far shallower side and front yards (15 ft versus 50 ft side), so RR is materially more buildable than AR on an identically sized lot. Accessory apartment permitted by special use permit under § 165-23. | 1 ac | 20% | 8,712 sq ft | 35 ft |
Footprint is the ground-floor building area, so a second storey buys floor area this number does not constrain, subject to the height limit. Some municipalities write their coverage cap as impervious surface rather than building coverage, which counts the driveway, walks and patio against the same budget and leaves less of it for the house - check which one your district uses before you design to it.
Local rules that move a build budget in Parma
- UtilityRG&E territory. Service run and connection cost depends on distance to the line, which on a rural parcel can be the single largest site expense.
- Short-term rentalsShort-term rentals allowed with local rules. Short-term rentals are REGULATED INSIDE THE ZONING CHAPTER ITSELF, not by a separate rental-licensing law — § 165-54 Short-term Rental (STR) sits in Article IV Use Standards, which is why a search of the Town Code's other chapters finds nothing. The rules are unusually tight and they bind on the OPERATOR, not just the building. An STR must be OWNER-OPERATED. No more than ONE non-resident of the premises may be engaged as an employee of the operation, so the model of a remote owner with a local cleaning-and-turnover crew does not fit. The unit is capped at FOUR GUEST ROOMS, with no more than four guest rooms sharing a single bathroom. Maximum length of stay for any guest is 30 CONSECUTIVE DAYS, which is the conventional line and unlike the Town of Gates' unusually long three-month definition elsewhere in this county. Guest parking may NOT be located in the front yard, and the Planning Board approves the location and screening of all required parking — so an STR approval in Parma runs through the Planning Board on the parking question even where the use itself is allowed. Because the STR standards are use standards rather than a district permission, read them together with the § 165-13 use table for the specific district: STR is not listed as a permitted or special-permitted use in every district, and the use table governs whether the use is available at all before § 165-54 governs how it operates. New York State's 2025 statewide registry (Ch. 99 of the Laws of 2025) applies on top. Confirm current practice with the Building Department at (585) 392-9449.

Building an accessory unit instead?
An 800 sq ft ADU in Parma runs about $200k–260k, and the per-square-foot rate is higher than a full house because the kitchen, bath, panel and heating plant cost the same either way. See what it costs to build an ADU in Parma, priced by size.

Cost to build in Parma: common questions
How much does it cost to build a house in Parma, NY?
A standard-finish new build in Town of Parma runs about $204–268/sq ft all in, general-contractor margin included, which puts a 1,800 sq ft house at roughly $370k–480k. A full basement, a sloped or wooded site, or a winter foundation pour each add to that, and a custom or luxury finish level moves it up again. Land is on top: a minimum conforming lot of 0.1148 acres runs about $886 here, for a combined $370k–480k.
What is the cheapest way to build in Parma?
The three levers that move a budget most here are finish level, foundation and site. Standard finish on a slab, on a flat and already-cleared lot, in the warm season, is the floor - every step away from that combination is priced in the tables above. Square footage matters less than people expect, because the per-square-foot rate barely moves between a 1,200 and a 2,500 sq ft house; what changes is the total.
Do I need a bigger lot to build in Parma?
The smallest residential minimum lot size in Town of Parma is 0.1148 acres, and the more rural districts go up to 1 acres. Which minimum applies depends on the district your parcel sits in, so confirm the district before you assume a lot is buildable.
Does it cost more to build in winter in Parma?
Yes. Foundation and site work carry a winter premium because of frost protection, heating and ground conditions, and at Monroe County pricing that works out to about +$2.8–4/sq ft across the whole build. It is usually cheaper to wait for spring than to pay it, unless the schedule is already costing you more somewhere else.
