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.

What applies everywhere in Nova Scotia

Outside Halifax, no Nova Scotia regulation requires municipalities to allow backyard suites or a set number of units per lot. Each municipality decides this in its land-use by-law. Province-wide, the Building Code applies to the suite, and a new on-site sewage system needs provincial notification or approval. [1][2][3][4][5][6]

Units allowed: No provincial minimum. The Minimum Planning Requirements Regulations under the Municipal Government Act (amended to N.S. Reg. 51/2025, effective March 7, 2025) say nothing about units per lot or backyard suites, so the number of units allowed is set by each municipality's land-use by-law. [1]
Units allowed: Under the Statement of Provincial Interest Regarding Housing, which applies to all communities, planning documents must include policies on affordable housing, special-needs housing and rental housing. Municipalities should consider higher densities, smaller lot sizes and reduced yard requirements. This is guidance for municipal plans and does not give a right to build a suite. [3]
Eligible land: Halifax only: under the HRM Minimum Planning Requirements Regulations, s. 4A(2)(c), HRM must permit residential uses in all zones except areas zoned for industrial, military, park, transportation reserve, utility, water supply, floodplain, Crown land, agriculture or conservation-organization ownership. This was amended by N.S. Reg. 196/2025, effective October 3, 2025. No equivalent rule applies to other municipalities. [2]
Parking: Halifax only: under HRM Minimum Planning Requirements Regulations s. 4A(2)(i), no on-site parking requirement applies to residential uses within the urban service area. There is no provincial parking rule for other municipalities. [2]
Building permit: The Nova Scotia Building Code Regulations adopt the National Building Code of Canada 2020 with Nova Scotia amendments (s. 4), and municipal building officials administer and enforce them. A suite of 37 m² or less building area is a "tiny house" under s. 2, and the Section 9.39 relaxations apply to it. [4]
Sewage: Installing, replacing or altering an on-site sewage system needs notification to the Department of Environment and Climate Change, submitted by a qualified person or professional engineer. A system that cannot meet the On-site Sewage Disposal Systems Regulations and Standard needs an approval (Activities Designation Regulations s. 7A). [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 · Middleton’s term: “single unit dwelling”

The by-law sets no minimum floor area or width for single unit dwellings, which are permitted in the Residential (R) and Residential Mixed Use (RMU) zones. It defines manufactured dwellings (CSA Z240) but does not restrict where they go.

Minimum dwelling size: None stated [7]
Minimum lot size: R zone single unit: 460 m² [7]

Nova Scotia-wide rule

Nova Scotia sets no provincial minimum house size. Since April 1, 2025, the Building Code Regulations define a "tiny house" as a dwelling unit of 37 m² or less in building area and give it its own rules on ceiling heights and lofts. Certified factory-built homes are deemed to meet the Code. Municipal planning documents must provide for manufactured housing. [1][4][3][8]

Tiny home on wheels or park model

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

We haven’t researched Middleton’s by-law for this yet.

What applies everywhere in Nova Scotia

The province's Building Code guidance says tiny homes on a permanent trailer chassis with wheels are outside the scope of the Nova Scotia Building Code Regulations. Whether you may live in one full-time is decided by the municipal land-use by-law. CSA Z240 manufactured (mini) homes are covered by the Building Code, and municipal plans must provide for manufactured housing. [8][4][3][2]

Building permit: Note A-9.39 in the province's Building Code users' guide (February 1, 2026) says tiny houses on a permanent trailer chassis with wheels "do not fall within the scope of the Nova Scotia Building Code Regulations" and may fall under other laws such as the Motor Vehicle Act. The guide says notes are explanatory and are not part of the regulations. [8]
Mobile homes: A CSA Z240 MH certified "manufactured home" is a building under the Building Code Regulations (s. 2). It is deemed to comply when marked under CSA A277 clause 7.4 (s. 10A(2)), and its installation is inspected at set stages (s. 35(1)(f)). [4]
Mobile homes: Municipal planning documents must provide for manufactured housing (Statement of Provincial Interest Regarding Housing, provision 4). Halifax only: HRM must permit manufactured housing, including converted shipping containers, in all residential zones (HRM Minimum Planning Requirements Regulations s. 4A(2)(l)). [3]
Approvals: Halifax only: HRM must permit temporary housing in non-permanent structures in all zones where it can be safely established (HRM Minimum Planning Requirements Regulations s. 4A(2)(k)). [2]

Bunkie or sleeping cabin

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

Not addressed · Middleton’s term: “accessory building”

The by-law does not mention sleeping cabins and does not prohibit human habitation of accessory buildings; accessory buildings follow the general limits in section 5.3.

Maximum height: 6.1 m (20 ft) [7]
Number allowed: No more than 3 accessory structures in a residential zone [7]
Setbacks: At least 0.6 m (2 ft) from a lot line, not in the front yard [7]
Separation from house: At least 2 m (6.5 ft) from the main building [7]

Nova Scotia-wide rule

Unless a municipal by-law says otherwise, Nova Scotia does not require a building permit for an accessory building of 20 m² or less, but the Building Code still applies to it. Adding a washroom brings in the on-site sewage rules, unless the building connects to a municipal sewer. [4][5][9]

Notes and caveats

Backyard suite omitted: the by-law has no accessory or backyard suite provision. Grouped dwellings (two or more architecturally similar, thematically designed, pre-serviced units in two or more buildings on one lot) are listed as permitted in the R zone (s. 7.1), and s. 5.25(b) allows grouped dwellings of six or fewer units as an exception to one main building per lot, but s. 2.5(a) still lists grouped dwellings among uses considered by development agreement. s. 7.6 waives the zone requirements when an existing accessory structure is converted to residential use. A person should ask the Town how a new detached suite is handled.
