West Nipissing zoning for small homes

Municipality of West Nipissing, a single-tier municipality. Population 14,583 (2021 census).

Backyard suite

A separate home in the yard of a house: garden suite, laneway suite or coach house, including prefab, modular or container units used this way.

Allowed · West Nipissing’s term: “detached additional residential unit”

Up to two additional residential units are permitted per lot in the R1–R4, Rural Residential, Rural and Agricultural One zones, and one of them may be in an accessory building. The Shoreline Residential zone and other privately serviced lots on a navigable watercourse allow only one unit, and it may not be a detached unit within the watercourse setback. [1]

Maximum size: No more than 75% of the habitable floor area of the main dwelling (s.4.1.1 b) [2]
Maximum height: The zone's accessory building height (6 m in R1–R4; 7.5 m in SR and RR, Table 6.3); up to 11 m in Rural (RU) and Agricultural One (A1) zones (s.4.1.3 d, e) [2]
Setbacks: Must meet the principal use's minimum front and side yard; at least 4.0 m from the principal dwelling; minimum rear yard 4.0 m (6.0 m in RU and A1) (s.4.1.3 c–e) [2]
Number allowed: Maximum two additional residential units per lot, of which no more than one in an accessory building (s.4.1, 4.1.3); one per lot in Shoreline Residential and on waterfront lots with private services (s.4.1.4) [2]
Parking: One space per additional residential unit, in addition to the main dwelling's parking (s.4.1.1 e) [2]
Servicing: Subject to adequate municipal or private on-site servicing to the Municipality's satisfaction (s.4.1.1 a) [2]
Where allowed: R1, R2, R3, R4, RR, RU and A1 zones; one unit in SR. Not within 300 m of the high-water mark of an at-capacity lake, and not in a boathouse or boat port (s.4.1, 4.1.4) [2]

Ontario-wide rule

Ontario law stops municipalities from banning one residential unit in a building ancillary to a detached house, semi-detached house or rowhouse on a parcel of urban residential land, as long as the lot has no more than three units in total. Municipalities still set most other zoning rules, but provincial law limits parking requirements, minimum unit size, lot coverage and separation distances. These units are also exempt from development charges and parkland dedication. [3][4][5]

Tiny home on a foundation

A small house as the main home on its own lot. The key rule is any minimum dwelling size.

Allowed · West Nipissing’s term: “single detached dwelling”

The residential and rural zone standards (Tables 6.3 and 9.3) set no minimum dwelling floor area for single detached dwellings. Lot size, yard and coverage rules apply.

Minimum dwelling size: None in the R1–R4, SR, RR, A1 or RU zone standards (Tables 6.3, 9.3) [2]

Ontario-wide rule

Ontario law sets no minimum total size for a house that is the main dwelling. The Building Code sets minimum room areas, so the smallest compliant dwelling is roughly 17.5 m² by the Province's own estimate. Municipalities may still set minimum floor areas for main dwellings in their zoning by-laws. The provincial ban on minimum sizes covers only additional residential units. [3][6][7][8][9][10][11]

Tiny home on wheels or park model

Living full-time in a tiny home on wheels or a park model home.

Allowed with limits · West Nipissing’s term: “mobile home dwelling / camping trailer”

A mobile home dwelling (CSA Z240) is a permitted principal use in the Shoreline Residential, Rural Residential, Mobile Home Residential, Rural and Agricultural One zones. Camping trailers, including motorhomes and fifth wheels, may not be used on a permanent basis between November 30 and April 15 unless in a recognized trailer park, and need proper sanitary services to stay on a lot permanently.

Where allowed: Dwelling, Mobile Home permitted in SR, RR and MHR (Table 6.1) and in A1 and RU (Table 9.1); mobile home parks in MHR only. The modular dwelling definition excludes park model trailers and Z240/Z241 units (s.3.57) [2]
Temporary garden suite: Not addressed in the general provisions. A camping trailer may be lived in while a principal dwelling is under construction with a building permit, for up to 2 years (s.4.30.1 d) [2]
Approvals: No camping trailer may be used on a permanent basis in any zone between November 30 and April 15 (s.4.26.2 a, 4.24.1 c). To stay on a lot permanently, a trailer needs black- and grey-water disposal built to the Ontario Building Code (s.4.26.2 b) [2]

Ontario-wide rule

Ontario has no single rule for living full-time in a tiny home on wheels. A unit on wheels can count as a 'building' that needs a permit and must meet the Building Code once it stays in one place, is hooked up to services or is anchored. Park model trailers are recognized only as seasonal recreational buildings. Municipalities may allow a portable garden suite under a temporary-use by-law for up to 20 years, with extensions of up to 3 years each. [11][6][3][8][7]

Bunkie or sleeping cabin

A small sleeping building with no kitchen, usually beside a cottage or house.

Allowed · West Nipissing’s term: “sleeping cabin”

One sleeping cabin without kitchen, cooking or bathroom facilities is permitted per lot in the Rural, Rural Residential and Shoreline Residential zones, and may be on the second storey of a detached garage.

Maximum size: 50.0 m² gross floor area (s.4.2.9 b) [2]
Maximum height: The zone's accessory building height: 7.5 m in SR and RR (Table 6.3) [2]
Number allowed: One sleeping cabin per lot (s.4.2.9 d) [2]
Kitchen: No kitchen, cooking or bathroom facilities (s.4.2.9 c; definition s.3.31) [2]
Setbacks: Must meet the principal use's minimum yard requirements (s.4.2.9 a) [2]
Where allowed: Rural (RU), Rural Residential (RR) and Shoreline Residential (SR) zones (s.4.2.9) [2]

Ontario-wide rule

Ontario law has no rule written specifically for bunkies or sleeping cabins. Whether one needs a building permit depends on the Building Code Act's definition of 'building' and the Code's shed exemption. That exemption covers only storage-use sheds, so it does not cover a structure used for sleeping. Municipal zoning rules for accessory buildings still apply. [8][6][3][12]

Notes and caveats

Council passed By-law 2026-58 on August 11, 2026, replacing By-law 2014-45. The municipality's OP/ZBL update page says the appeal period ended September 8, 2026 with no appeals and the by-law is in force (https://www.westnipissing.ca/official-plan-and-zoning-by-law-update/; notice: https://www.westnipissing.ca/notice-of-passing-comprehensive-zoning-by-law-2026-58/). Site-specific exceptions from 2014-45 are carried forward. The ARU link in our inventory is the DNSSAB funding program page, not a zoning guide, so guideUrl is null. The by-law has no garden suite provision. Schedules are separate PDFs on the update page.
