Lock-off suites are allowed in multi-family housing. The R1 zone allows up to 4 dwelling units per lot, counting the principal and accessory units. The City says accessory dwelling units can be permitted in all residential zones if requirements are met. A garden suite may not be in the front yard, except suites attached to garages.\n\n## Steps\n\n1. Check your zone and any Development Permit Area in zoning-lookup.\n2. Confirm the size and parking rules below with Development Services.\n3. Apply for a building permit with drawings before work starts.\n4. Allow for the City's requirements, such as a 45-minute fire separation and egress windows in bedrooms.\n\n## Good to know\n\n- Size: one accessory dwelling unit per principal dwelling. A secondary suite may be at most 90 m² or 40% of the building's habitable area, whichever is less. A garden suite may be at most 90 m². The minimum suite size is 22 m². Lock-off suites: 45 m² or 40%, whichever is less. The City's guide says an attached suite cannot exceed 40% of the living floor space or 970 square feet.\n- Parking: the bylaw requires 0.25 parking space per accessory dwelling unit for new buildings, and 1 space per accessory unit in the Parking Specified Area (Schedule D). Fractions round to the nearest whole number. The City's guide says one off-street space per additional unit. The bylaw prevails, but confirm with Development Services.\n- A development permit is needed only if the property is in a Development Permit Area. The guide says a small-scale R1 project outside one may not need it.\n- No owner-occupancy requirement is stated in the bylaw or the guide.\n- Utility fees apply to each unit.\n- The City says it is updating its zoning, so these rules may change.","sources":[{"url":"https://www.princerupert.ca/sites/7/files/2024-07/USE_THIS_Consolidated%20Zoning%20Bylaw_Draft07152024.pdf","title":"Consolidated Zoning Bylaw No. 3462 (PDF, consolidated June 24, 2024), City of Prince Rupert","accessed":"2026-11-05"},{"url":"https://www.princerupert.ca/sites/7/files/2026-03/CPR%20Development%20Procedures%20Guide_Final_Oct2025_linkedTOC.pdf","title":"Development Procedures Guide (PDF), City of Prince Rupert","accessed":"2026-11-05"},{"url":"https://www.princerupert.ca/media/117","title":"Building Bylaw No. 3314, 2012 (PDF), City of Prince Rupert","accessed":"2026-11-05"},{"url":"https://www.princerupert.ca/building-development/building-and-development-fees","title":"Building and Development Fees, City of Prince Rupert","accessed":"2026-11-05"},{"url":"https://www.princerupert.ca/city-hall/contact-city-department","title":"Contact a City Department, City of Prince Rupert","accessed":"2026-11-05"},{"url":"https://www.princerupert.ca/city-hall/bylaws-policies/bylaw-ticketing-fine-payment-and-disputes","title":"Bylaw Ticketing, Fine Payment and Disputes, City of Prince Rupert (City Hall hours)","accessed":"2026-11-05"}],"sources_read":"2026-11-05","review":{"status":"machine_checked","badge":"Checked against official text","label":"Checked by script, not yet by a person: the official wording behind 6 of 6 facts was matched to the official text."},"urls":{"html":"https://govhandbook.com/ca/bc/prince-rupert/secondary-suite/","markdown":"https://govhandbook.com/ca/bc/prince-rupert/secondary-suite.md","json":"https://govhandbook.com/ca/bc/prince-rupert/secondary-suite.json"}}
