Does a deck count as impervious area?

  • Open slatted decking, a deck surface constructed of boards (wood or composite wood) with intermittent gaps that allow water to pass through to the surface below. Only open, uncovered decks installed over a permeable surface (dirt, no concrete or gravel) do not count towards your built-upon calculations. If the decking is not slatted or it is placed over an impervious surface, then it is considered impervious. 

What size deck can I install?

  • Please review Article 8.8.9. If you would like assistance reviewing your proposed structures please contact us at Ask A Planner with your parcel ID or address and the size and type of deck you are proposing. 

Do I need a building permit for a deck?

  • Yes, all decks are load bearing structures and require a building permit. Building permits are issued by Mecklenburg County. 

Are there setbacks for a deck?

  • Yes. Decks are subject to the same setbacks as the home.
