Build a coach house

A coach house is a detached compact home, usually built in the rear yard of a single-family residential lot.

Sometimes called a laneway house or carriage home, a coach house can provide you with additional rental income, while increasing the diversity of rental housing choices in single family neighbourhoods.

A coach house can't be sold separately from the main house or placed under strata title.

We're simplifying the coach house process

Coach houses play an important role in meeting our goal of diversifying housing options.

We're considering a number of changes to simplify the coach house application process, including new or simplified permitting requirements, changes to allowable floor space, revised parking requirements, and more.

Under the proposed changes, some lots would qualify for a more simplified process, while others would continue with the existing process.

  Lot eligibility criteria Process (one-storey coach house)  Process (two-storey coach house)
Proposed new process 
  • open lane access
  • at least 49.2 ft (15m) wide
  • a minimum area of 5,000 sq ft (464.5 sq m)
  • within the urban containment boundary
Building permit
  • Development permit issued by staff
  • Followed by a building permit
Existing process Corner lot at least 50 ft (approx 15m) wide Development Variance Permit (requires council decision) Development Variance Permit (requires council decision)
Existing process At least 10,000 sq ft (929 sq m) with no lane access Development Variance Permit (requires council decision) Development Variance Permit (requires council decision)
