Agricultural, Ag & Mining - The three acre minimum is per family, not per lot, so a two-family dwelling needs six acres and the figure scales with the unit count. The 25% coverage cap includes accessory buildings.
- A nonresidential use needs ten acres and 400 ft of frontage, and a recreational facility 50 acres.
- Where a side or rear yard adjoins a street, the front yard standard applies to it under § 52C.
- Yards are measured from the foundation under § 52G.
- Cluster development under § 50O and multiple dwellings under § 50K change the lot requirement.
Multi-Use & B1 - No side yard is required here except where the lot abuts property in residential use. A side yard that is then provided must be at least 12.5 ft, and where the lot abuts a residential district at least 100 ft.
- The three acre minimum is per family, not per lot, so a two-family dwelling needs six acres.
- A nonresidential use needs the same three acres, on 200 ft of frontage rather than 250 ft.
- This district reaches three storeys, and no minimum living space is published.
- Where a side or rear yard adjoins a street, the front yard standard applies to it under § 52C.
- Yards are measured from the foundation under § 52G.
- Cluster development under § 50O and multiple dwellings under § 50K change the lot requirement.
Multi_Use and Agricultural - No district of this name appears in the zoning ordinance, so it carries no dimensional standard of its own. The label reads as two district names run together, the way a parcel with split zoning is shown, so resolve the parcel to its actual district on the Town Zoning Map.
Land Conservation 1, Land Conservation 2 - The Density Control Schedule leaves this district's row entirely blank. The figures shown match the row printed directly above it, so they may carry down or the town may publish no dimensional standard here: confirm them with the town before relying on them.
- Where a side or rear yard adjoins a street, the front yard standard applies to it (§ 52C).
- Yards are measured from the foundation (§ 52G).
Residential - The three acre minimum is per family, not per lot, so a two-family dwelling needs six acres and the figure scales with the unit count. The 25% coverage cap includes accessory buildings.
- A nonresidential use needs fifteen acres and 400 ft of frontage, five times what a dwelling needs, and a recreational facility needs 50 acres.
- Where a side or rear yard adjoins a street, the front yard standard applies to it under § 52C.
- Yards are measured from the foundation under § 52G.
- Cluster development under § 50O and multiple dwellings under § 50K change the lot requirement.
Residential/Recreational - The ordinance sets no dimensional standard for this district at all: it has no row in the Density Control Schedule. § 30(6) establishes it for seasonal dwellings on smaller lots than the town's other residential areas, but never says how much smaller, so confirm with the town.
Multi-Use Recreational - This district publishes neither a side nor a rear yard standard. The three acre minimum is also per family, not per lot, so a two-family dwelling needs six acres.
- A nonresidential use needs the same three acres, on 200 ft of frontage rather than 250 ft.
- The 30% coverage cap includes accessory buildings.
- Yards are measured from the foundation under § 52G.
- Cluster development under § 50O and multiple dwellings under § 50K change the lot requirement.
Short-term rentals
No local short-term-rental law on record - which is not the same as permission. The Town of Knox has no local short-term rental law, and that is not permission. Confirm with the town before counting on renting a house short term.
Conditions the code attaches:

- The ordinance does define a bed and breakfast: an owner-occupied one-family dwelling offering overnight lodging and breakfast only to transient occupants, sharing a common exterior entrance.
- It also defines a boarding house as any dwelling lodging more than four persons for hire, which expressly includes a rooming house or furnished-room house.
