Zoning requirements

Whether a permit is required or not for your project, always check with the Planning Division to make sure your project meets the standards of your zoning district.

For example your 90 square storage shed may be too small to require a permit.  However, you’ll want to make sure you place the shed in a location that is allowed per the zoning of your neighborhood.

Your lot may also contain conservation easements, utility easements, floodplains or other areas that will restrict location of structures or amenities.

Grading requirements

A grading permit may be needed when you are

  • Disturbing more than 1,000 square feet of earth
  • Altering a stabilized slope
  • Adding more than 1,000 square feet of concrete or asphalt
  • Bringing more than 100 cubic yards of earth onto the property
  • Clearing vegetation which encompasses more than 1,000 square feet
