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.
EXCEPTION: If you are replacing window(s) or doors(s) but not altering the framing, commonly referred to as retrofit inserts, a building permit is not required. This includes patio doors.
How do I get this permit? Window and door replacement permits are issued over the counter.
