Building Permits

Permit Requirements

A permit is required for most construction and/or repair projects, including electrical, plumbing, and mechanical work. Permits are necessary for, but not limited to, residential and business additions; alterations; patios; decks; garden and retaining walls; swimming pools; spas; hot tubs; air conditioners (adding or replacing); and all electrical and plumbing installations, including lawn sprinklers, water heaters, and gas lines.

When Building Permits Are Not Required

Permits are not required for the following:

  • Fences below eight feet in height. Contact the Planning Division for plan approval before construction, 
  • Retaining walls that are not more than three feet in height, measured from the top of the footing to the top of the wall, unless supporting a surcharge or ground slope of five percent (5%).  Please note: The presence of a building / structure within five feet or existence of a geogrid is a surcharge.
  • One-story detached accessory buildings with no electrical or plumbing installed, provided the floor area does not exceed 120 square feet, that are less than eight feet in total height and do not block any windows of the dwelling; zoning clearance is required before construction.
  • Raised wood decks, which are less than 30 inches above the ground at all points
  • Painting, papering, carpeting, and similar finish work
