Skylight Permit Requirements
The on-line skylight permit is available for properties in Sunnyvale with a residential zoning district when the installation will not cut any structural framing members (i.e. roof rafters or ceiling joists). Zoning district information is available on-line by clicking on E-Zoning.

If a permit is not available on-line, the permit can be obtained at the One-Stop Permit Center, City Hall, 456 W. Olive Avenue between the hours of 8:00 am to 12:00 noon and 1:00 pm to 5:00 pm Monday through Friday.

This permit will allow the installation of a skylight. Following are the minimum requirements that must be met based on the 2007 California Building Codes:
  • All plumbing vents must be located ten feet away, or terminate three feet above, an operable skylight.
  • During the inspection, provide the building inspector with the ICC number for skylight(s). (CBC 2405.5)
  • Plastic skylights shall not be a minimum of four feet from each other, unless:
    • the skylights are located within the same room or space and the maximum area of the skylights is 100 square feet, or
    • the building is equipped throughout with a automatic fire sprinkler system. (CBC 2610.6)
  • Operable skylights shall be ten feet from all plumbing vents or the vent shall terminate three feet above the skylight. (CMC 802.8)
  • Smoke alarms to be provided in all sleeping rooms and adjacent hallways, multi-levels, and basements. (CBC 907.2.10)
The Skylight Permit is NOT available on-line if you are:
  • Cutting structural framing members (i.e. roof rafters or ceiling joists) for the skylight installation.
If the condition above applies, the permit shall be issued at the One-Stop Permit Center, City Hall, 456 W Olive Avenue. Specific process information is available at the Building Division web site.

Inspections
  • Two inspections are required. The first inspection is a rough framing inspection where the skylight is installed and the framing is still exposed. A final inspection should be scheduled after all the work is completed.
