Interior Renovation Permit
Interior Renovations That DO Require a Permit
- Removing or altering load-bearing walls
- Changing the layout or structure of a space
- Adding or modifying plumbing fixtures (kitchens, bathrooms)
- Updating or installing HVAC systems
- Finishing or converting a basement
- Creating a secondary suite or rental unit
- Renovating a commercial interior space
Interior Renovations That do NOT Require a Permit
- Cosmetic updates (painting, flooring, cabinetry)
- Replacing fixtures without moving plumbing
- Minor repairs that don’t affect the structure or systems
If you’re unsure, this is where we help. We’ll review your project and tell you exactly what’s required before you start. Interior renovation permits are commonly required when the work changes structure, layout, plumbing, HVAC, fire separations, exits, or commercial occupancy conditions. Cosmetic work such as painting, flooring, and cabinet replacement may not require a permit if no regulated building systems are changed, but the scope should be confirmed before construction begins.
With the right engineering and permit team, the interior Renovation process can be smoother, faster, and more predictable.
