# Whistler secondary suite and carriage house rules

**Question:** Can I add a secondary suite or a carriage house in Whistler?

**Short answer:** Yes, in many Whistler zones. Where a zone limits a parcel to a detached dwelling, one auxiliary residential dwelling unit is allowed inside the dwelling or in an auxiliary building (carriage house). You need a building permit, and often a development permit first.

**Who handles it:** Municipal (Resort Municipality of Whistler, https://www.whistler.ca)  
**Cost:** See the building-permit-fees answer.  
**How long:** See the building-permit answer. The Municipality does not give a fixed time.  
**Where:**

## How it works

Under [Zoning and Parking Bylaw No. 303](https://www.whistler.ca/wp-content/uploads/Zoning-_and_Parking_Bylaw_303_2015_2026-08-07.pdf), where a zone limits a parcel to a detached dwelling, the permitted uses include one auxiliary residential dwelling unit, either inside the dwelling or in an auxiliary building. Single-family zones such as RS1 list it as a permitted use. Zone rules vary, so check yours (see zoning-lookup).

In RS1, RS2, RS3, RI1 and RSE1 zones an auxiliary building may be up to 90 m² if it holds only the unit; in RS1 up to 110 m² if it also holds parking. Other zones set their own limits.

## Steps

1. Confirm your zone and whether a development permit is needed. Planning: 604-935-8170.
2. Apply for a building permit (see building-permit). New accessory dwelling units need home warranty insurance.
3. Provide one parking space per auxiliary residential dwelling unit.

## Good to know

- Each dwelling unit must be at least 32.5 m².
- Under the small-scale multi-unit rules, a suite inside a detached dwelling may not exceed 40 per cent of that dwelling's gross floor area.
- Serviced parcels of 4,050 m² or less in the urban containment area may have three units (280 m² or less) or four units (larger). At least one unit (three units) or two units (four units) must be residential rental tenure. Parking is one space per unit, with at most six spaces on the parcel.
- Extra floor area (56 m²) in RS1 for employee use and rental needs an employee housing agreement.
- We found no owner-occupancy rule in the zoning bylaw.
