*There are restrictions related to demolishing a building or structure that is 50 years or older. The Historic Preservation Board Review Team reviews all demo permits for structures 50 years or older. If it is determined that the building may have historical significance, the permit is referred to the Historic Preservation Board for consideration of a stay of issuing the permit. The Historic Preservation Board may issue a stay up to 90 days. The stay may be appealed to the City Council.

Fees and payments

Fees are based on the estimated value of work being done. Payment is due when permits are issued. You may pay with a check, cash, or credit card (Visa or MasterCard only). Permit fees larger than $10,000 must be paid with a check or wire transfer.
