Building Services

Please use online services

Washington County Department of Land Use & Transportation continues to provide most services remotely - online, by phone or via U.S. Mail.

Though our lobbies are opening June 3 (see hours/locations below) we urge all customers to continue to conduct business remotely whenever possible to help mitigate the spread of COVID-19. 

Customers entering lobbies will be asked to provide their contact information for contact-tracing purposes. Customers will also be asked to practice physical distancing (at least six feet of separation), consider wearing a facial coverings and to adhere to restrictions on occupancy limits.

Thank you for your cooperation.
