# Nelson secondary suite and carriage house rules

**Question:** Can I add a secondary suite or a laneway house?

**Short answer:** In Nelson, secondary suites and laneway houses are allowed in most residential zones, and a building permit is always required. A dwelling unit must be at least 26 square metres, and a suite needs one on-site parking space. Check your zone first.

**Who handles it:** Municipal (City of Nelson, https://www.nelson.ca)  
**Cost:** Building permit: $100 for the first $5,000 of value plus $9 per $1,000 or part above that. A laneway house over 5 m high also needs a development permit ($450). The $500 suite application fee is listed as waived through April 23, 2021; ask whether it is charged now.  
**Where:**
- Phone: Development Services and Engineering, 250-352-8260
- Email: Development Services, development@nelson.ca

## Key facts

- **Secondary suite allowed:** Yes, in zones that permit Small-Scale Residential (up to four dwelling units on a lot, where a secondary suite may have a shared or interior entrance), such as R1. The City says suites are permitted in most residential zoning; check your zone on the zoning map.

- **Coach house or garden suite allowed:** The Zoning Bylaw sets laneway house heights in the R1, R2, R3, GP1, N1, C2, CD5 and CD7 zones. In R1 the maximum is 5.8 m, or 6.1 m for an above-garage suite. A laneway house needs a permanent foundation and cannot be strata titled.

- **Limits:** A dwelling unit must have at least 26 m² gross floor area. R1 allows 3 dwelling units on lots 280 m² or less and 4 on larger lots. A laneway house footprint cannot exceed the greater of 65 m² (over 4.5 m high), 89 m² (up to 4.5 m high) or 8% of the lot. (Sources differ: Conflict: the City's page gives the footprint for a laneway house up to 4.5 m high as 80 m² and a maximum gross floor area of 89 m²; the bylaw gives 89 m² as the footprint for that height, so the value follows the bylaw. The page also says 5 m maximum height without a development permit; the bylaw sets 5.8 m (a development permit is needed over 5 m, per the OCP). No owner-occupancy requirement was found in the Zoning Bylaw (searched 'owner', 'occupied').)

## How it works

The City says secondary suites and laneway houses are permitted in most residential zoning. [Zoning Bylaw 3652](https://nelson.civicweb.net/document/31803) (April 2026) allows Small-Scale Residential, up to four dwelling units on a lot including a secondary suite, in zones such as R1, R2, R3 and R5. A laneway house is allowed in R1, R2, R3, GP1, N1, C2, CD5 and CD7. Setbacks, density and coverage depend on your zone. The City reviews each application case by case.

## Steps

1. Check your zone on the Interactive Zoning Map (see the zoning-lookup answer).
2. Call Development Services about the site and water and sewer connections; call Nelson Hydro about electrical servicing.
3. Submit a building permit application with the matching checklist. Laneway houses over 5 m high also need a development permit.

## Good to know

- Every dwelling unit must be at least 26 m² gross floor area. In R1, lots of 280 m² or less may have 3 dwelling units and larger lots 4.
- Laneway house height in R1: up to 5.8 m, or 6.1 m for an above-garage suite. The footprint may not exceed the greater of 65 m² (over 4.5 m high), 89 m² (up to 4.5 m high) or 8% of the lot. It needs a permanent foundation and cannot be strata titled. The City's page gives 80 m² and 5 m; the bylaw says otherwise, so confirm.
- Parking: 1 space per dwelling unit. If the house existed before February 3, 2014 and has no off-street parking, the requirement applies only to the new suite or laneway house. The Director of Development Services may waive it in two cases: time-restricted street parking with a covenant, or two on-lot spaces plus street parking.
- A laneway house with a building permit application received on or after June 12, 2018 cannot be a short-term rental.
- The City says a secondary unit not used as a short-term rental gets a 75% discount on water and sewer.
- All dwelling units must meet emergency access requirements.
