In Calgary, most renovations that change the structure, layout, plumbing, electrical, or heating of your home require a building permit — including basement developments, additions, moving walls, and legal suites — while purely cosmetic updates like painting, flooring, or cabinet swaps generally do not. Permit rules are enforced by the City of Calgary, and separate trade permits for electrical, plumbing, and gas are often needed alongside the building permit. As part of every OCR project, we handle the permitting so your renovation is inspected and done to code.
