Do I need a permit to replace deck boards?
Replacing the walking surface (decking) without modifying the substructure may be exempt in some municipalities. Replacing structural components (joists, beams, posts, ledger board) requires a permit.
Can I rebuild my deck in the same footprint without a permit?
No. A complete deck rebuild requires a permit even if you are rebuilding in the same location. Current code requirements (footing depth, railing height, hardware) must be met.
What if the existing deck was built without a permit?
You may need to bring the entire structure up to current code. Many municipalities require a full permit review for any work on an unpermitted structure.
