Brampton zoning for small homes

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 · Brampton’s term: “garden suite”

One garden suite plus one attached additional residential unit is permitted on a lot with a detached, linked, semi-detached or townhouse dwelling on its own lot, in the rear or interior side yard. New By-law 14-2026 and old By-law 270-2004 both apply, with the more restrictive rule prevailing, until the appeals of 14-2026 are resolved. [1][2]

Number allowed: A maximum of 2 additional residential units per residential lot: one attached ARU and one garden suite, or two attached ARUs (By-law 14-2026, s.5.2.C.2) [3]
Maximum size: By-law 14-2026: gross floor area up to 100 m² with a detached dwelling, 50 m² in all other cases (s.5.2.C.15.b). City garden suite page (By-law 270-2004 rules): 80 m² in Hamlet, Estate or Agricultural zones, 35 m² in all other residential zones. The more restrictive figure applies [4]
Maximum height: By-law 14-2026: the lesser of the principal building's height or 6.0 m with a detached dwelling, 4.5 m with a townhouse or semi-detached dwelling, 7.5 m in Residential Hamlet or Estate zones (s.5.2.C.15.f). City page (270-2004): the lesser of the principal dwelling's height or 4.5 m (7.5 m in Hamlet, Estate or Agricultural zones) [3]
Setbacks: By-law 14-2026: 1.2 m rear and interior side, 3.0 m for any part above 3.0 m high (s.5.2.C.15.c-d). City page (270-2004): 2.5 m rear, 1.8 m side [3]
Separation from house: By-law 14-2026: at least 4.0 m between any wall of the garden suite and any main wall of the principal dwelling (s.5.2.C.15.e). City page (270-2004): 3.0 m [3]
Parking: No additional space for a lot with one ARU; one additional space where a lot has more than one ARU; tandem parking permitted (By-law 14-2026, s.5.2.C.8, .9, .11) [3]
Approvals: A Custom Home - Garden Suites Review application to the Planning Division (architectural control, zoning, grading, servicing and drainage review; $530 fee), then a building permit; each ARU must also be registered under the ARU Registration By-law [4]

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. [5][6][7]

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 · Brampton’s term: “detached dwelling”

By-law 14-2026 sets no minimum dwelling floor area. In the posted consolidation of By-law 270-2004, the residential zones have none either, though some site-specific exception zones and the Agricultural (A) zone do. Lot and setback standards still apply. [3]

Minimum dwelling size: None in By-law 14-2026. By-law 270-2004 (City-posted consolidation dated 2013): none in the parent residential zones; Agricultural (A) zone "Minimum Ground Floor Area for main building: 170 square metres for one storey and 115 square metres for more than one storey" (s.46.1.2); some exception zones set 75-100 m² [8]

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. [5][9][10][11][12][13][14]

Tiny home on wheels or park model

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

Not allowed · Brampton’s term: “travel trailer / house trailer / mobile home”

By-law 270-2004 states that travel trailers, house trailers and mobile homes may not be located in any zone if used for the accommodation of persons. Because the more restrictive by-law prevails, that rule still applies. By-law 14-2026 excludes house trailers and mobile homes from the definition of building, defines a travel trailer as short-term or seasonal, and has no mobile home zone.

Where allowed: Nowhere: "Travel trailers, house trailers and mobile homes may not be located in any zone if used or intended to be used in that location for the accommodation of and occupation by persons" (By-law 270-2004, s.6.19(a), 2013 consolidation) [8]
Parking: Travel trailers and recreational vehicles may not be parked or stored in a front yard or exterior side yard of a residential lot; one recreational vehicle up to 7.0 m long and 2.7 m high may be stored on the lot under conditions (By-law 14-2026, s.5.2.S) [3]

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. [14][9][5][11][10]

Bunkie or sleeping cabin

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

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

By-law 14-2026 does not permit habitable space, which it defines to include space for sleeping, in any accessory building unless the by-law explicitly allows it. By-law 270-2004 says accessory buildings in residential zones shall not be used for human habitation.

Where allowed: "Unless explicitly permitted by this By-law, habitable space shall not be permitted within any accessory building or structure" (By-law 14-2026, s.3.1.A.2); habitable space "shall mean any portion of an accessory building or structure used or capable of being used for sleeping, cooking (with plumbing) sanitary facilities (with plumbing), etc." (Chapter 2) [3]
Maximum size: By-law 270-2004 (2013 consolidation): accessory building gross floor area up to 23.0 m² in Residential Hamlet or Estate zones and on Agricultural lots of 2 ha or less, 10.0 m² in other residential zones; "shall not be used for human habitation" (s.10.3(c), (e)) [8]

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. [11][9][5][15]

Notes and caveats

Council passed Comprehensive Zoning By-law 14-2026 on February 4, 2026. The City says it is under appeal and that both 270-2004 and 14-2026 apply, with the most restrictive provisions prevailing, until the OLT brings unappealed portions into force. By-law 14-2026 does not apply to excluded areas, including the Downtown Brampton MTSA, the Main Street North Development Permit System area and several other protected MTSAs, which stay under 270-2004. The 14-2026 PDF read is marked 'Final for Council Adoption | February 4, 2026'. The 14-2026 links on escribemeetings.com returned 403 (bot block), so the copy linked from brampton.ca was used. The only 270-2004 text the City posts is a consolidation last modified in 2013, which predates garden suites. Its garden suite figures therefore come from the City's garden suite page, not the by-law text, and other 270-2004 provisions quoted (s.6.19, s.10.3, s.46.1.2) may have been amended since 2013. The Garden Suite Grant Program closed on July 21, 2025.
