Permits

Below are some of the most common permits issued by the Building Division:

Building Permit

Most construction, from new construction to alternations and repairs, requires a building permit. There are two types of building permits:

  • Building with No Plan Check

    For simpler projects that do not require building plans. (May still require a site plan.)
  • Building with Plan Check

    For projects that require building plans.

But in some cases, a building permit is not required:

No Building Permit Required

Simple projects that do not require a building permit. Building codes must still be followed and other permits might still apply (e.g. Well & Septic, Use, or Zoning).
