Residential Homeowners Guide to Building Permits


Zoning regulates how close your deck can be to your property lines. Zoning regulations apply to decks whether or not a permit is required.

Regulations for decks vary depending on:

  • the zone,
  • the yard the deck is located in and
  • the design of the deck (height, roofed).
