Can you build an ADU in Malta, NY?

R-1 Residential - These figures are the one-family standard: every other use here carries its own minimum lot size, frontage, coverage, height and yards. A lot on Route 67 east of Round Lake or Little Round Lake takes a 75 ft front yard instead of 50.

• The 200 ft is frontage along the road, and the code sets no width at the building line; § 167-16 sets a separate minimum road frontage for flag lots.

• For equids and hens the lot size, frontage and coverage apply to the entire premises, while the yards and height apply only to the buildings related to keeping them.

• A mobile home park may include tiny houses as defined in § 167-2, which must sit on a foundation rather than on wheels and be connected to water and sewer.

• The 100 ft is frontage along the road, and the code sets no width at the building line; § 167-16 sets a separate minimum road frontage for flag lots.

R-5 Agricultural Residential - A lot on Route 67 east of Round Lake or Little Round Lake takes a 75 ft front yard instead of 50, and here that reaches every use in the district. These figures are the one-family standard: each other use carries its own lot size, frontage, coverage, height and yards.

• A two-family dwelling is a special permit use and costs no additional land, the same 1.8365 acres and frontage as a one-family dwelling, but its coverage cap rises from 18% to 25%.

• A two-family dwelling is a special permit use on the same 1.8365 acres and 300 ft of frontage as a one-family dwelling, with coverage rising from 18% to 25%.
• Agriculture with other poultry, livestock and fowl needs 400 ft of frontage on at least 217,000 sq ft at 15% coverage, with 50 ft front and side yards and a 30 ft rear.
• Agriculture excluding those animals is a permitted principal use on at least 217,000 sq ft with only 200 ft of frontage.
• Equids take 130,680 sq ft on 200 ft and hens 20,000 sq ft on 100 ft; for both, lot size, frontage and coverage apply to the entire premises and the yards and height only to their buildings.
• A library or museum may reach 60 ft of height with a 60 ft front yard, on at least 100,000 sq ft with 300 ft of frontage.

• A two-family dwelling takes the full 217,000 sq ft and 300 ft of frontage, the same as a one-family dwelling, with coverage rising from 18% to 25%; it is the most expensive duplex in Malta by land.

• The 300 ft is frontage along the road, and the code sets no width at the building line; § 167-16 sets a separate minimum road frontage for flag lots.

• Where a parcel is split between this district and another, § 167-15 rather than the district standards decides what may be built, so check that first.
• At least 50% of the site must be green space for every use other than a residential one, on top of the 15% building coverage cap.

C-2 Commercial Route 9 - A one-family and a two-family dwelling are both permitted principal uses on the same standard, but the residential exclusion zone shown on the official zoning map prohibits both outright, along with townhouses, on the Route 9 North and Route 67 West corridors.

• Whether a parcel sits inside that mapped exclusion decides whether the residential uses exist for it at all, so check the map before pricing housing here.
• A bar, beer garden, brew pub, office or restaurant needs at least 20,000 sq ft on 100 ft of frontage, and most other commercial uses 40,000 sq ft on 200 ft.

• A multiple dwelling is prohibited within a mixed commercial use.

Route 67 West Overlay - A one-family and a two-family dwelling are prohibited outright here, and the only residential use left, a multiple dwelling, carries a 500 ft front yard. Where the overlay and the underlying district conflict, the overlay applies.

• Every other use in the overlay takes the 50 ft front yard.

• The overlay adds uses to the underlying district rather than replacing it.

C-3 NYSERDA - The 80 ft height is not uniform by use: a fitness centre or a recreation facility is held to 50 ft, while light industry, research and development, conference centres, museums and libraries reach the full 80 ft.

• The 20,000 sq ft and 100 ft of frontage are the office standard, with 30% of the site as green space.

• The 100 ft is frontage along the road, and the code sets no width at the building line; § 167-16 sets a separate minimum road frontage for flag lots.

C-5 Exit 11 Hamlet - A one-family and a two-family dwelling are both permitted principal uses on the identical standard, so a duplex needs no more land than a house: at least 40,000 sq ft on 200 ft of frontage, 30 ft of height, a 50 ft front yard, 15 ft side and 30 ft rear.

• C-5 and C-5A share that residential standard and differ in which commercial uses each carries, so check the uses rather than the dimensions.
• The 200 ft is frontage along the road, and the code sets no width at the building line; § 167-16 sets a separate minimum road frontage for flag lots.

C-5A Auto Exit 11 Hamlet - A one-family and a two-family dwelling are both permitted principal uses on the identical standard, so a duplex needs no more land than a house: at least 40,000 sq ft on 200 ft of frontage, 30 ft of height, a 50 ft front yard, 15 ft side and 30 ft rear.

• This district carries the same dimensions as C-5 wherever the two share a use; what differs is which commercial uses each one allows.
• The 200 ft is frontage along the road, and the code sets no width at the building line; § 167-16 sets a separate minimum road frontage for flag lots.

• A senior multiple dwelling takes the identical figures.
• A one-family or two-family dwelling keeps a 50 ft front yard, a 15 ft side and a 30 ft rear rather than the 40, 20 and 40 the commercial uses take.
• Against an existing residential development or a filed residential plat, a Planning Board buffer with a screening and opacity requirement applies here as well.
• At least 30% of the site must be green space on the commercial standard.

• The residential buffer and opacity requirement that binds C-7, C-8 and C-9 does not reach this district.

DN-4 Downtown Neighborhood - Lot area, setbacks and coverage are set by the building type under § 3 of the downtown code rather than by the district, so the four-storey cap is the one dimension the district itself fixes. Across the building types four storeys appears as 50 feet.

DC-4 Downtown Civic - Lot area, setbacks and coverage are set by the building type under § 3 of the downtown code rather than by the district, so the four-storey cap is the one dimension the district itself fixes. Four storeys appears as 50 feet in the types that permit it.

DX-3 Downtown Mixed-Use, RA-3 Downtown Residential Attached - Lot area, setbacks and coverage are set by the building type under § 3 of the downtown code rather than by the district, so the three-storey cap is the one dimension the district itself fixes. Across the building types three storeys appears as 40 feet.

GC-3 Green Corridor - Buildings here may not exceed three stories under § 2 of the downtown code, and that is the one dimension the district itself fixes: lot area, setbacks and coverage are set by the building type under § 3 instead.

DA-2 Downtown Arts - Lot area, setbacks and coverage are set by the building type under § 3 of the downtown code rather than by the district, so the two-storey cap is the one dimension the district itself fixes. Two stories is 30 feet on one building type and 35 feet on another.

DP-2 Downtown Park - Lot area, setbacks and coverage are set by the building type under § 3 of the downtown code rather than by the district, so the two-storey cap is the one dimension the district itself fixes. Two stories appears as 35 feet in the types that permit it.

RD-2 Downtown Residential Detached - Lot area, setbacks and coverage are set by the building type under § 3 of the downtown code rather than by the district, so the two-storey cap is the one dimension the district itself fixes. Two stories appears as 35 feet in the building type standards.

OS Downtown Open Space - At least 95% of the site must be permanent outdoor amenity space and there is no on-site parking, which is the standard that decides what can be built here, ahead of the 10 ft setbacks and 20 ft of height.

• That 95% is a floor on outdoor amenity space rather than a ceiling on building coverage, and the two are not interchangeable.
• This district states its dimensions directly rather than through a building type.
