The Building Permit Process

Obtaining a Building Permit

Step 1. Check you Zoning

  • Check your Base Zoning and Full Zoning using our GIS viewer and our Zoning Ordinance
  • Your Zoning Ordiance article(s) will tell you what you can buile, where you can build, how high you can build, etc. on your parcel.
  • For example, if the GIS viewer has your Base Zone as "R1" and Full Zone with "SC" and "WW" you would read R1 SC and WW in the Zoning Ordinance to figure what you can do on your property.
  • For more information on what you can and cannot do on your property, please visit our Planning Division website.
