Why you need permits

  • It’s the law. State Building Code requires that permits be obtained for certain types of work. Permits provide a legal record of work performed.
  • Permits protect you, your family, your business and your investment. (They are designed to help ensure that licensed contractors do the work when required.)
  • Inspections ensure that work is done safely and that it meets the minimum code requirements.
  • Minor problems that could lead to costly repairs, liability and life/safety issues can be detected during permit inspections and brought to your attention before the situation worsens.
  • When selling a property, the buyer, realtor and/or lender may require that unpermitted work be corrected, properly permitted and inspected before closing.
  • Lack of permits and inspection approvals may void insurance.
