City of Hudson, NY: zoning for new construction
Hudson is a dense small city and it zones like one - lot minimums across its twelve districts run from about 0.09 to 0.28 of an acre, so you're working with village-scale parcels, not rural acreage. Short-term rentals are among the most restricted in the region: the city caps total licenses at 25 city-wide, requires owner-occupancy, and adopted a moratorium on new licenses in 2024 that the 2025 ordinance tightened further. If a rental is central to your plan here, that cap is the first thing to check - call the Building Department at (518) 828-3133.

One-Family Residential — R-1 publishes a total lot area and no per-dwelling-unit figure — one family, one lot. The Planning Board may approve a front yard that conforms with the PREVAILING BUILDING SETBACK for the street the property is on (residential note 4), instead of the figure above. Density and the number of lots a parcel may be subdivided into are calculated under § 325-18C on NET parcel size. Article V carries alternative dimensions for conservation development and incentive zoning.
One- or Two-Family Residential — R-2 appears in only one column of the schedule, the one- or two-family one, so it has no per-use variants. The Planning Board may approve a front yard that conforms with the PREVAILING BUILDING SETBACK for the street the property is on (residential note 4), instead of the figure above. Density and the number of lots a parcel may be subdivided into are calculated under § 325-18C on NET parcel size. Article V carries alternative dimensions for conservation development and incentive zoning.
Multiple Dwelling Residential — THE BASE ROW IS "R-3 Multiple Dwellings". R-3 appears in FOUR columns of the two schedules: one- or two-family, attached dwellings, multiple dwellings, and — in the commercial schedule — new office structures or structures combining office and residential use, at 10,000 sq ft on a 100 ft lot with a 10 ft front, 15 ft side and 30 ft rear yard at 30% coverage. Usable open space 400 sq ft per dwelling unit; maximum building length 160 ft. The Planning Board may approve a front yard that conforms with the PREVAILING BUILDING SETBACK for the street the property is on (residential note 4), instead of the figure above. Density and the number of lots a parcel may be subdivided into are calculated under § 325-18C on NET parcel size. Article V carries alternative dimensions for conservation development and incentive zoning.
Multiple Dwelling (High-Density) — THE BASE ROW IS "R-4 Multiple Dwellings". R-4 also appears in the one- or two-family and attached-dwelling columns, both recorded as variants. Its side yard is note 3: ten feet OR HALF THE BUILDING HEIGHT, whichever is greater — the 10 ft recorded is the floor. Usable open space 300 sq ft per dwelling unit; maximum building length 160 ft. The Planning Board may approve a front yard that conforms with the PREVAILING BUILDING SETBACK for the street the property is on (residential note 4), instead of the figure above. Density and the number of lots a parcel may be subdivided into are calculated under § 325-18C on NET parcel size. Article V carries alternative dimensions for conservation development and incentive zoning.
Institutional-Residential Conservation — I-R-C publishes a total lot area and no per-dwelling-unit figure. Usable open space 500 sq ft per dwelling unit. The Planning Board may approve a front yard that conforms with the PREVAILING BUILDING SETBACK for the street the property is on (residential note 4), instead of the figure above. Density and the number of lots a parcel may be subdivided into are calculated under § 325-18C on NET parcel size. Article V carries alternative dimensions for conservation development and incentive zoning.
Riverfront Gateway — The side yard is note 3: ten feet OR HALF THE BUILDING HEIGHT, whichever is greater — the 10 ft recorded is the floor. Usable open space 300 sq ft per dwelling unit; maximum building length 160 ft. The Planning Board may approve a front yard that conforms with the PREVAILING BUILDING SETBACK for the street the property is on (residential note 4), instead of the figure above. Density and the number of lots a parcel may be subdivided into are calculated under § 325-18C on NET parcel size. Article V carries alternative dimensions for conservation development and incentive zoning.
Core Riverfront — C-R has the smallest land-per-dwelling-unit figure in the city, 1,000 sq ft, and the only 20 ft rear yard among the residential districts. Usable open space 400 sq ft per dwelling unit. The Planning Board may approve a front yard that conforms with the PREVAILING BUILDING SETBACK for the street the property is on (residential note 4), instead of the figure above. Density and the number of lots a parcel may be subdivided into are calculated under § 325-18C on NET parcel size. Article V carries alternative dimensions for conservation development and incentive zoning.
Recreational Conservation — R-C publishes a total lot area and no per-dwelling-unit figure. Usable open space 500 sq ft per dwelling unit. The Planning Board may approve a front yard that conforms with the PREVAILING BUILDING SETBACK for the street the property is on (residential note 4), instead of the figure above. Density and the number of lots a parcel may be subdivided into are calculated under § 325-18C on NET parcel size. Article V carries alternative dimensions for conservation development and incentive zoning.
City Core Commercial — C-C publishes NO minimum lot area, lot depth, front yard or rear yard — the commercial schedule prints a dash for each. Its side yard is "none required, but a ten-foot minimum if provided" (note 2), and WITHIN 25 FT OF A RESIDENCE DISTRICT BOUNDARY the side yard becomes 10 ft and the rear yard 30 ft. Four storeys and 45 ft is the tallest in the city. Density and the number of lots a parcel may be subdivided into are calculated under § 325-18C on NET parcel size. Article V carries alternative dimensions for conservation development and incentive zoning.
Commerce District — Commerce publishes no front yard. Its side yard is "none required, but a ten-foot minimum if provided" (note 2), and WITHIN 25 FT OF A RESIDENCE DISTRICT BOUNDARY the side yard becomes 10 ft and the rear yard 30 ft. Density and the number of lots a parcel may be subdivided into are calculated under § 325-18C on NET parcel size. Article V carries alternative dimensions for conservation development and incentive zoning.
General Commercial — WITHIN 25 FT OF A RESIDENCE DISTRICT BOUNDARY the side yard becomes 15 ft and the rear yard 30 ft. Area devoted to manufacturing is capped at 10,000 sq ft (note 3). Density and the number of lots a parcel may be subdivided into are calculated under § 325-18C on NET parcel size. Article V carries alternative dimensions for conservation development and incentive zoning.
Industrial — I-1 publishes NO minimum lot area, lot width, lot depth or front yard. Its 45 ft is a CAP, not the limit: note 4 allows two feet of building height for each one foot of distance from any property line, up to 45 ft — so the permitted height depends on setback. WITHIN 25 FT OF A RESIDENCE DISTRICT BOUNDARY the side and rear yards both become 40 ft, four times the 10 ft otherwise required. Density and the number of lots a parcel may be subdivided into are calculated under § 325-18C on NET parcel size. Article V carries alternative dimensions for conservation development and incentive zoning.
