Laneway Suites in Toronto: Design, Permits & Construction
A laneway suite is a self-contained home built on the same lot as a detached house, semi-detached house or townhouse, typically in the back yard beside a public laneway and completely detached from the main house. Toronto homeowners build them for multi-generational living, for adult children or aging parents, or as long-term rental housing. Novacon Construction designs and builds laneway suites in Toronto as a full design-build service: feasibility, design, permits and construction under one team.
Laneway Suites in Toronto at a Glance
- Who we are: a licensed, bonded and insured Toronto design-build company based in Scarborough, building custom homes, major additions and ADUs since 2004, with over 500 projects completed. Best of Houzz 2025 award recipient.
- Built by a custom home builder: a laneway suite is a small, fully serviced house on a tight lot. We bring the same zoning review, structural engineering, permitting and construction management we use on our Tarion-registered custom homes and second-storey additions.
- Typical timeline: about 3 to 6 months for design and permits, then 6 to 9 months of construction depending on complexity, so roughly 9 to 15 months in total.
- Firm fixed price: every Novacon contract is firm fixed price, so you know your construction cost before work begins.
- A boutique builder: we take on a limited number of major projects each year, typically 6 to 10, so we can give each one the attention it needs from planning to handover.
- Where they’re allowed: since July 2019, laneway suites are permitted across the City of Toronto in R, RD, RS, RT and RM zones on residential lots that share a property line with a public lane, subject to the zoning by-law’s criteria.
- The checks that decide feasibility: lane frontage, emergency access from the street within Toronto Fire Services’ travel-distance limits, protection of nearby trees, servicing, and the size and setback limits in the zoning by-law for your lot.
- Budget: laneway suites typically start around $350,000 and vary widely with size, site conditions and servicing. City building permit fees in 2026 are $18.56 per square metre plus $56.33 per new unit, and eligible owners can apply to the City’s development charge deferral program.
- What we handle: feasibility review, architectural design, structural engineering coordination, permit drawings and applications, construction and City inspections, with a dedicated project manager, $5 million liability insurance, WSIB coverage and a 2-year warranty.
- Laneway or garden suite? A laneway suite needs a public lane; a garden suite is the option for back yards without one. See all of our ADU services.
