Many homeowners are not aware when a permit is required. As a general rule, the answer is YES - any construction work that is regulated by adopted building codes and fire and public safety regulations requires a permit before work can begin. The best way to find out if you need a permit is to call the Building Department. Discuss your plans with Building Department staff before you begin construction to determine whether you need a permit. The staff member will answer your construction questions and may provide valuable advice.
