Window and Door Replacement Permit

Why do I need this permit?

A building permit is required for some of the following reasons:
  • The Building Code regulates the amount of light and ventilation that must be provided for all habitable rooms as well as the minimum size for emergency exits from all bedrooms
  • The size of the opening and the overall size of the replacement windows and doors shall not be less than the size of the existing structures; If the rough framing around the structure is being changed or if an additional openings are installed in an existing exterior wall, the requirements of the current code must be met.
  • If the building is located in the Wildland Urban Interface (WUI) Area a permit is required and tempered glass must be installed.
  • EXCEPTION: If you are replacing window(s) or doors(s) including patio doors, but not altering the framing, commonly referred to as retrofit inserts, a building permit is not required, unless the building is located in the Wildland Urban Interface (WUI) Area.
