Since Calgary changed the secondary suite zoning rules, can we add a basement suite in Woodbine without rezoning?

Yes, you can add a basement suite in Woodbine without rezoning. Calgary's blanket rezoning to the Residential Grade-Oriented (R-CG) district allows secondary suites city-wide, including established communities like Woodbine.

Under Calgary's current zoning rules, secondary suites are permitted as-of-right in all residential districts, including the R-CG district that now covers most of Calgary's residential areas. This means you don't need to apply for a rezoning or discretionary use — secondary suites are an allowed use. However, you still need to go through the proper permit process to ensure your suite meets all safety and building code requirements.

The permit process involves two key steps: First, you'll need a development permit from the City of Calgary, which you can apply for online at calgaryplanningpermit.ca. This typically takes 6-8 weeks to process and ensures your suite complies with zoning requirements like parking, unit size, and entrance locations. Second, you'll need building permits for any construction work — electrical, plumbing, framing, and a general building permit. The building permit process ensures your suite meets Alberta Building Code requirements for fire separation, egress, ceiling heights, and life safety systems.

Alberta Building Code requirements for basement suites are strict and non-negotiable. Your suite must have proper fire separation (typically 5/8" drywall on the ceiling between floors), egress windows in all bedrooms that meet minimum size requirements, interconnected smoke alarms throughout the house, separate electrical panels or sub-panels, and minimum ceiling height of 1.95 meters (6'5"). The suite also needs a separate entrance, though it can be internal stairs if properly designed. Many Woodbine homes from the 1970s-1980s have good basement ceiling heights, but you'll need to verify yours meets the minimum.

Typical costs for a basement suite conversion in Calgary range from $60,000 to $120,000, depending on the existing conditions and finish level. This includes permits, electrical work (often requiring a panel upgrade from 100A to 200A service), plumbing for a bathroom and kitchen, framing, insulation, drywall, flooring, and all finishes. The return on investment is strong — basement suites in Woodbine typically rent for $1,200-$1,800 per month depending on size and finishes.

Next steps: Start by having a contractor assess your basement to confirm ceiling heights, electrical capacity, and structural conditions. Then apply for your development permit while planning the construction details. All electrical, plumbing, and gas work must be done by licensed contractors and inspected by Safety Codes Officers accredited through the Safety Codes Council of Alberta.
