Do I need a permit to knock down a wall inside my house in Surrey?

Yes, you likely need a permit to remove an interior wall in Surrey, especially if it's load-bearing or contains utilities. Even non-structural walls often require permits when electrical, plumbing, or HVAC systems are affected.

Understanding Load-Bearing vs Non-Load-Bearing Walls

The most critical factor is whether the wall is load-bearing (supporting the structure above). Load-bearing walls typically run perpendicular to floor joists and are often located near the center of the home or directly under beams above. Removing a load-bearing wall without proper engineering and permits can cause serious structural damage, sagging floors, and create major safety hazards. Under the BC Building Code (BCBC 2024), any structural modifications require permits and often engineered drawings.

Non-load-bearing partition walls may seem simpler, but they still frequently require permits in Surrey. If the wall contains electrical wiring, plumbing lines, or HVAC ducts, you'll need permits for those trades. Even a simple partition wall removal can trigger permit requirements if it affects fire separations, egress routes, or room ventilation requirements.

Surrey-Specific Permit Process

Contact the City of Surrey Building Department at 604-591-4086 or visit surrey.ca/renovating-building-development/building for specific requirements. Surrey's permit fees typically range from $200-800 for interior alterations, depending on complexity. The process usually takes 2-4 weeks for simple non-structural work, longer if structural engineering is required.

Surrey requires detailed drawings showing existing and proposed conditions, including any affected utilities. If structural work is involved, you'll need stamped drawings from a Professional Engineer registered in BC. All electrical work must be done by a contractor licensed with Technical Safety BC (TSBC), and plumbing modifications require a licensed plumber.

When to hire a professional

Never assume a wall is non-load-bearing without professional assessment. A structural engineer or experienced contractor can determine this, but the safest approach is getting proper permits regardless. The consequences of unpermitted structural work include insurance claim denials, difficulty selling your home, and potentially dangerous structural failures.

First, have a qualified contractor or structural engineer assess whether the wall is load-bearing.
