Can I have both a secondary suite and a laneway house on my property?

Yes, you can have both a secondary suite and a laneway house on most Vancouver properties, provided your lot meets the size and zoning requirements for both.

Under Vancouver's current zoning rules, single-family properties can typically accommodate up to three dwelling units total: the main house, one secondary suite (either basement or above-grade), and one laneway house. This combination is quite popular and represents an excellent way to maximize rental income while maintaining your primary residence.

Key requirements you'll need to meet include:
Your lot must be large enough to support both structures while meeting setback requirements. For the laneway house specifically, you'll need lane access and sufficient lot depth (typically 110+ feet). The laneway house can be up to 25% of your lot area (so 1,000 sq ft on a standard 33x120 lot) and up to 2.5 storeys. Your secondary suite must have a separate entrance, proper egress windows, fire separation from the main house, and interconnected smoke alarms throughout the property.

Both projects require building permits and must comply with BCBC 2024, including the new seismic bracing requirements that took effect March 10, 2025. The laneway house specifically must be built by a Licensed Residential Builder registered with BC Housing and will be covered by 2-5-10 home warranty insurance. The secondary suite work, depending on scope, may require licensed trades for electrical, plumbing, and gas connections through Technical Safety BC.

Budget considerations are significant - a secondary suite renovation typically runs $40,000-$80,000 depending on whether you're finishing existing basement space or converting above-grade areas. A new laneway house ranges from $150,000-$300,000+ depending on size and finishes. However, the rental income potential is substantial in Vancouver's tight rental market, with secondary suites renting for $1,500-$2,500/month and laneway houses commanding $2,000-$3,500/month.

Your next steps should be: First, confirm your specific zoning allows both (most R1-1 zones do, but check with the City at 311). Then get a preliminary site assessment from an architect or designer to ensure your lot can accommodate both structures with proper setbacks and parking requirements. Apply for permits well in advance - Vancouver's permitting process can take 4-8 weeks for simple projects and much longer for complex ones.
