Rural Residence Agriculture 1 — A SECOND DENSITY ROW APPLIES: besides the one-acre minimum lot, Appendix B sets a "Required minimum density per lot" of THREE ACRES in RRA-1. The two are different questions and only the lot minimum was recorded. Lot area with and without public sewage is the same one acre here. On a corner lot the side yard abutting the side street is 25 ft, a third figure distinct from both the single and the combined side yard above. Minimum FRONTAGE is 60 ft, separate from the lot width. Required setbacks are measured from a point 25 FT FROM THE CENTRE LINE of any town, county or subdivision roadway (note c), not from the property line. Parking is permitted within a required setback (note b). Accessory building dimensions are set by § 190-27A(3) (note d). Where public sewage is not available, no lot may be built upon that lacks space for a private sanitary waste disposal system (note a). Total lot coverage also applies to ground-mounted solar energy facilities under § 190-15E(2) (note e).

ADUs vs. short-term rentals in Ghent

No local short-term-rental law on record - which is not the same as permission for Town of Ghent. No local STR ordinance found as of Jun 2026. Town has a general rental property inspection chapter (Ch. 136) but no STR-specific permit or registration requirement. These are separate questions from whether you can build an ADU — a unit you're allowed to add isn't automatically one you're allowed to rent nightly, so check both.
