Permits
Do I need a permit for my remodel?
The honest answer is that it depends on your scope and your jurisdiction — and that anyone giving you a confident blanket answer isn't reading your project.
It depends on scope and jurisdiction. As a rule of thumb, structural changes, electrical, plumbing, mechanical and anything that changes the building envelope generally require a permit; pure cosmetic replacement often doesn't. The only reliable answer comes from your city's building department for your specific scope.
Why we won't publish a checklist per city
Because it would be wrong somewhere, and a wrong permit answer is expensive in a way a wrong price estimate isn't. Requirements differ between jurisdictions, and they change. We ask the building department directly on every job rather than working from a table someone wrote two code cycles ago.
Call your city's building department, describe your scope specifically — "I'm moving this wall, relocating a drain, adding these circuits" — and ask what permits that triggers. It is a free phone call and it is the only authoritative answer.
The general shape of it
| Type of work | Typically |
|---|---|
| Painting, flooring, replacing cabinets in place | Usually no permit |
| Swapping a fixture for a like-for-like fixture in the same location | Often no permit |
| Moving a wall — any wall | Permit. Load-bearing also means engineering |
| Relocating plumbing or adding drains | Permit |
| New circuits, a panel upgrade, or rewiring | Permit |
| Changing windows or doors in size or position | Permit |
| Adding square footage of any kind | Permit, and usually planning review too |
| Anything affecting egress, fire separation or structure | Permit, without exception |
Treat that as orientation, not authority. Your scope and your city decide.
Why unpermitted work is worse than it sounds
- It surfaces at resale. Square footage that doesn't match county records, or an inspection that flags work with no permit history, becomes a price negotiation at the worst possible moment.
- Insurance. A claim arising from unpermitted work is a fight you may not win.
- It has to be opened back up. Retroactive permitting frequently means exposing finished work so an inspector can see what's behind it. You pay twice for the same wall.
- It compounds. The next contractor inherits it, and on older homes prior unpermitted work is one of the most common hidden conditions we find once demolition starts.
Who should pull the permit
Your contractor should, under their licence. If a contractor asks you to pull an owner-builder permit for work they are performing, treat that as a serious warning sign — it shifts liability onto you and is sometimes a sign the contractor isn't properly licensed for the work.
On our jobs we carry the submittal and the plan-check corrections. That is the part people underestimate: it is rarely one submission and done, and chasing corrections is work.
