The purpose of codes is to provide minimum requirements to safeguard public safety, health and general welfare.  (2009 IRC, Section R101.3)

 

PERMITS

            Do I need a permit to paint my home?

No, permits are not required for cosmetic improvements such as painting or carpeting your home.  However, permits are required for siding, roofing, replacing windows, accessory buildings, interior remodels, and furnace/air conditioning replacement.  Contact the Planning Department if there is a question of whether a permit is or is not required.

            If the County issues me a building permit, but the building inspector finds code violations when performing an inspection,

           does having a permit make those violations allowable?

The issuance of a permit shall not be construed to be approval of any violations of any provisions of County codes.  The issuance of a permit based on construction documents and other data shall not prevent the building inspector from requiring corrections of errors in the construction documents and other data.  (2009 IRC, Section R105.4)

 

            How soon must I begin work once I have received a permit?
