What demolition can I do myself?

Most interior, non-structural demolition can be safely done by homeowners, but you'll need to identify what's structural, what contains utilities, and what requires permits before swinging that sledgehammer. The key is understanding the difference between cosmetic demo and work that affects your home's structural integrity or safety systems.

Interior demolition you can typically handle yourself includes removing drywall, trim, baseboards, interior doors, non-load-bearing partition walls, flooring (hardwood, laminate, carpet), kitchen cabinets, bathroom vanities, and non-plumbing fixtures like towel bars. You can also remove ceramic tile, though this is labor-intensive work. These projects mainly require basic tools, patience, and proper disposal planning.

Before starting any demolition in Ottawa, you'll need to determine if permits are required. The City of Ottawa requires building permits for structural changes, but cosmetic removals typically don't need permits. Call 613-580-2424 or check ottawa.ca/building if you're unsure. However, if you're removing walls, even non-load-bearing ones, it's worth confirming with the city that no permit is needed.

Safety considerations are crucial for DIY demolition. Always shut off electricity to the area and check for wiring before cutting into walls. Ottawa's older homes, particularly in areas like the Glebe or Centretown, may contain asbestos in drywall compound, floor tiles, or insulation. Homes built before 1978 likely have lead paint. For suspected asbestos or lead, hire certified professionals for safe removal - this isn't worth the health risk.

What you absolutely cannot do yourself includes anything involving structural elements (load-bearing walls, beams, posts), electrical work (which requires ESA permits and inspection), plumbing changes (moving or capping lines), and gas line work (requires TSSA-certified technicians). Even if you're just "opening up" a wall, you need to verify it's not load-bearing through a structural engineer or experienced contractor.

Ottawa-specific considerations include proper waste disposal through the city's construction waste program or private disposal companies. Many older Ottawa homes have unique structural elements that aren't obvious - post-war bungalows in Alta Vista or Elmvale may have steel beams hidden in walls, while heritage homes downtown often have load-bearing masonry that's not immediately apparent.

Your next steps should be: first, identify all utilities in the demolition area using a stud finder with electrical detection. Second, take photos before starting in case you need to reference original construction. Third, rent a dumpster or arrange disposal - demo creates more waste than you expect. Finally, if you have any doubt about structural elements or hidden utilities, consult with professionals before proceeding. A quick consultation fee is much cheaper than repairing damage from improper demolition.
