Where does your property reside?

Depending upon where your property is located will determine which building department you will contact to get the answers you need. To learn which jurisdiction your property resides, input your address in Metro's MetroMap website and contact the appropriate building department.

Additions? Garage conversions? New decks, sheds or fences? Give us a call!

Are you thinking about making changes to or on your existing property? Many changes may need to be approved through the Current Planning Development Assistance section. It's important to check with this section prior to applying for a building permit. In-person assistance is available Monday through Friday 8 a.m. - 4 p.m. during walk-in lobby hours. Phone assistance is available Monday through Friday 8 a.m. - 5 p.m.
