About Building Departments

How much does a building permit cost?

Building permit fees vary significantly from one locality to another. The fees are usually based on the total cost of the project.

If I have been issued a building code violation, can I appeal?

Yes, a building code violation can be appealed. In most cases, a local board will hear building code appeals. An appeal should be filed as soon as possible, as some jurisdictions impose deadlines for submitting appeals. The appeals process may require a fee.

Can the Building Department recommend a local home improvement contractor?

Local Building Departments are generally reluctant to recommend specific contractors. However, many will provide a list of licensed contractors that serve the local area.
