Annexation Policies

To incorporate a home into the City of Charleston, the property must be:

  • Contiguous or "touching" the city limits
  • Located on the City side of the Urban Growth Boundary
  • Approved by the City Council

Annexation Fees

Annexation is free. Eligible homeowners simply fill out an application and submit it to the City of Charleston Planning Division at the address listed on the form. Next, your application is read by City Council and the Planning Commission for approval. Once approved, we will send you a welcome letter and brochure of City services. We will contact your service providers (i.e. CWS, Fire, Police, Trash, etc) for you.
