Allowed with limits · Norwich’s term: “detached additional residential unit”

A detached additional residential unit is permitted as of right only in the R1, R2, R3 and CC zones in the serviced Village of Norwich. In other settlements and rural areas, a detached unit requires a planning application and a lot of at least 0.6 ha. [1][2]

Where allowed: As of right in R1, R2, R3 and CC zones in the Village of Norwich; in R1, R2, V, RE, RR zones in unsewered settlements and RR, RE, A1, A2 zones outside settlements, subject to approval of a planning application (Table 5.6.2.4, as replaced by By-law 04-2026-Z) [3]
Number allowed: 1 detached additional residential unit per lot (Table 5.6.2.4, By-law 04-2026-Z) [3]
Minimum lot size: Village of Norwich: per the zone provisions for the principal dwelling; elsewhere 0.6 ha (1.48 ac) (Table 5.6.2.4, By-law 04-2026-Z) [3]
Maximum size: Cumulative dwelling unit area of all additional units: 50% of the principal dwelling or 100 m² (1,076 ft²), whichever is less (settlements); 50% or 140 m² (1,507 ft²) outside settlements (Table 5.6.2.3, By-law 04-2026-Z) [3]

Servicing: In a settlement, the principal dwelling must be connected to municipal water and/or sewage with capacity confirmed by the County in writing; not permitted on lots on private communal systems (s.5.6.2.2, By-law 04-2026-Z) [3]
Temporary garden suite: A garden suite requires a temporary use by-law under s.39 of the Planning Act for up to 20 years; one storey, maximum 158 m² (1,700 ft²); occupancy limited to the owner's retired parents/grandparents or a retiring owner (s.5.11) [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. [4][5][6]

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 with limits · Norwich’s term: “single detached dwelling”

The R1 zone sets a minimum gross floor area of 93 m² (1,001 ft²). No minimum dwelling floor area was found in the A1, A2, RR, RE, R2 or V zone sections reviewed.

Minimum dwelling size: 93 m² (1,001 ft²) minimum gross floor area in the R1 zone (Table 11.2) [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. [4][7][8][9][10][11][12]

Tiny home on wheels or park model

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

Needs approval · Norwich’s term: “mobile home / trailer / garden suite”

A dwelling is defined to exclude trailers, tents, mobile homes, motor homes and recreational vehicles, except that a mobile home may be a second accessory dwelling to a farm in the A1 or A2 zones; there is no mobile home park zone. Recreational vehicles may not be used for permanent occupancy, and a garden suite needs a temporary use by-law. [13][14]

Where allowed: "A dwelling may include a mobile home for the purposes of a second accessory dwelling to a farm in the A1 or A2 Zones" (definition 4.36, as replaced by By-law 05-2026-Z) [3]
Temporary garden suite: Requires a zoning amendment under s.39 of the Planning Act authorizing temporary use for up to 20 years (s.5.11.1) [1]
Approvals: "No recreational vehicle ... shall be used for permanent home occupancy while stored on any lot" (s.5.30.3) [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. [12][7][4][9][8]

Bunkie or sleeping cabin

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

Not allowed · Norwich’s term: “accessory building”

Accessory buildings may not be used for human habitation except as permitted in the by-law, and no provision for sleeping cabins or bunkies was found. Bunkhouses are only mentioned for seasonal farm workers. [13]

Where allowed: Accessory building "is not to be used for human habitation except as permitted in this Zoning By-Law" (s.5.1.1.2) [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. [9][7][4][15]

Notes and caveats

Section PDFs are linked from Oxford County's page on cdn.umb-sites.dev, whose TLS certificate had expired; the same files were read from www.oxfordcounty.ca/media/... (same media IDs). The county page states the consolidation is as of March 31, 2026, but the 'Council approved by-laws' list (Aug 30, 2026) shows 04-2026-Z (Feb 24, 2026) and 05-2026-Z (Mar 10, 2026) are NOT yet consolidated; both were read from the scanned by-law copies in that PDF. 04-2026-Z replaces s.5.6.2 (ARUs), adds 5.6.2.5 (detached ARUs on A1/A2 lots in serviced settlements), removes the 55 m² garden suite minimum, and bars garden suites on lots with a detached ARU. 04-2026-Z and 05-2026-Z each replace Table 5.1.1.3 (accessory uses) with different versions (R1-R3 accessory height 5.5 m vs 4.5 m), so general accessory height was not reported. Consolidated R1 Table 11.1 still says outside the Village only an internal ARU is permitted. Agricultural Zoning By-law Review under way (2025). Mobile home use as a farm accessory dwelling: it is not clear whether this is as-of-right in A1/A2 or only via site-specific zones (e.g. A2-34).
