Windows and doors building permit

You need a permit if you are replacing exterior doors or windows. This includes garage doors.

If your project includes other renovations, such as a kitchen or bath remodel, use the residential renovation or addition permit type.

If the project is a replacement in-kind, it is exempt from design review if it meets design review exemption #32. If you are replacing an existing wood window or door with a new window or door made of wood with aluminum or fiberglass exterior cladding, it is exempt if there is no change in:

  • The size or location of the window or door
  • The operation of the window or door
  • The recess of the window or door from the exterior wall surface

  • The divided lite pattern (if any), provided that any new divided lites are either true divided lites or 3-dimensional simulated divided lites

All other projects may require design review approval first.

Replacement or new windows in sleeping rooms need to meet the minimum requirements for emergency egress:

  • 20” clear opening width
  • 24” clear opening height
  • 5.7 sf clear net opening area
  • Max sill height of 44” above the finished floor
  • Clear opening area may be reduced to 5.0 sf if opening on grade floor

  • Exception: sash replacement only, in an existing opening that does not reduce the opening. See CRC section R310 for more information.
