Norfolk County zoning for small homes

Norfolk County, a single-tier municipality. Population 67,490 (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 · Norfolk County’s term: “detached additional residential dwelling unit”

One detached additional residential dwelling unit (plus one interior unit) is permitted with a single detached, semi-detached or street townhouse dwelling in the R1-R4, Hamlet Residential (RH) and Agricultural (A) zones, on municipal or private services. It is not permitted with a vacation or seasonal dwelling, in a farm building, or on the same lot as a garden suite.

Where allowed: R1, R2, R3, R4, RH and A zones (s. 3.2.3 a) [1]
Number allowed: Maximum three dwelling units per lot: primary, one interior and one detached additional unit (s. 3.2.3 e) [1]
Maximum size: 75 m² (807 sq ft) usable floor area, including any basement, excluding attached garage (s. 3.2.4.2 b) [1]
Maximum height: 5 m (s. 3.2.4.2 e) [1]
Setbacks: 1.2 m from interior side and rear lot lines (none to a lane); not in a front or exterior side yard (s. 3.2.4.2 c, d) [1]
Separation from house: Entirely within 40 m of the primary dwelling (s. 3.2.4.2 f) [1]
Parking: 1 off-street space in addition to the primary dwelling's spaces (s. 3.2.4.2 h) [1]
Servicing: Permitted with municipal water and wastewater or private water and septic systems (s. 3.2.3 k) [1]

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. [2][3][4]

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 · Norfolk County’s term: “dwelling, single detached”

The R1, RH, Resort Residential and Agricultural zone provisions set no minimum floor area for a single detached dwelling; lot area, frontage, yard and height rules apply.

Minimum dwelling size: No minimum usable floor area in the R1, RH, RR or A zone provisions (40 m² minimums apply only to dwelling units in certain commercial zones) [1]

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. [2][5][6][7][8][9][10]

Tiny home on wheels or park model

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

Allowed with limits · Norfolk County’s term: “mobile home / recreational vehicle / park model trailer”

Residential use of a trailer, recreational vehicle or other vehicle is prohibited in all zones except a mobile home where specifically permitted, and a recreational vehicle (including a park model trailer) may not be used as a principal residence. Mobile homes are permitted only through site-specific provisions such as mobile home parks, or as a farm bunk house.

Where allowed: Mobile homes only where specifically permitted, e.g. site-specific mobile home parks (s. 14.378, 14.379); a mobile home may be used as a farm-worker bunk house (s. 2.27) [1]
Temporary garden suite: No general garden suite permission or definition found; s. 3.2.3 g only says a lot may not have both a detached additional unit and a garden suite [1]

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. [10][5][2][7][6]

Bunkie or sleeping cabin

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

Not allowed · Norfolk County’s term: “accessory building”

In the Resort Residential (RR) zone, which covers vacation-home areas, no accessory building may contain a habitable room (defined to include sleeping rooms) or washroom facilities. Other zones' accessory building rules do not expressly permit or prohibit sleeping space.

Kitchen: RR zone: no accessory building or structure shall contain a habitable room or washroom facilities (s. 5.8.3) [1]
Maximum size: General accessory buildings: 55 m² in R1-R6, 100 m² in other zones, 200 m² in the A zone, max 10% lot coverage (s. 3.2.1 g) [1]
Maximum height: Accessory buildings: 5 m in R1-R6, 7 m in RR, 8 m in A, 6 m elsewhere (s. 3.2.1 a) [1]

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. [7][5][2][11]

Notes and caveats

Consolidation copy as of February 1, 2026, labelled a working version for convenience only. A housekeeping amendment to 1-Z-2014 was in public consultation (open house April 22, 2026); the notice gives no detail on ARU or trailer rules and no adoption date. The section numbering for detached units is printed as 3.2.4.2 though internal references cite 3.2.3.2. The inventory's guide page covers accessory buildings generally, not additional residential units, so guideUrl is null. Bunkie answer is based on the RR zone rule; in A and other zones the by-law is silent on sleeping use of accessory buildings.
