Can I build a tiny home in my backyard as a rental in Fredericton?

Building a tiny home as a rental in Fredericton requires careful navigation of zoning bylaws, building codes, and rental regulations. The City of Fredericton has updated its zoning to allow secondary suites in many residential areas, but a backyard tiny home faces additional hurdles as a separate structure.

Zoning and Permits
Contact the City of Fredericton Development Services at (506) 460-2020 first to confirm your property's zoning allows accessory dwelling units. Fredericton's zoning bylaw permits secondary suites in many zones, but these are typically within the main house or as basement apartments. A detached tiny home may be classified as an accessory building, which has different rules for size, setbacks, and occupancy.

You'll need a building permit from the City of Fredericton regardless of size. Under the National Building Code of Canada 2020 (effective May 1, 2025 for new applications in NB), any structure intended for human habitation must meet full code requirements including fire separation, egress windows, proper insulation (Tier 2 energy efficiency), and structural standards. The common misconception that tiny homes under a certain size are exempt doesn't apply to rental units.

Code Compliance Challenges
A rental tiny home must meet the same safety standards as any dwelling. This includes interconnected smoke and carbon monoxide alarms, proper electrical service (requiring an NB Power wiring permit at 1-800-615-0522), plumbing connections to municipal services or an approved septic system, and adequate heating. All electrical work must be done by a TIS-licensed electrician, and plumbing requires a licensed plumber - both trades require permits and inspections through NB's Technical Inspection Services at 1-888-659-3222.

Practical Considerations
Fredericton's frost line extends over 4 feet deep, requiring a proper foundation. Tiny homes on wheels or temporary foundations won't meet building code for permanent occupancy. Municipal water and sewer connections add significant cost - expect $8,000-$15,000 just for service connections, plus the expense of running lines across your property.

Alternative Approaches
Consider converting existing space like a garage or basement into a legal secondary suite instead. This often proves more cost-effective and faces fewer zoning obstacles. If you're set on new construction, a small detached dwelling unit (not technically a "tiny home") built to full code standards may be possible depending on your lot size and setback requirements.

Next Steps
Schedule a pre-application meeting with Fredericton Development Services to review your specific property and discuss options. They can clarify whether your zoning permits accessory dwelling units and what the approval process involves. Getting clarity upfront prevents costly mistakes down the road.
