Why are Building Permits and Inspections Required?

• To protect you, your family, friends, neighbors, and neighborhood from work that does not meet minimum construction standards.

• To ensure that work performed on your property is safe, meets environmental standards, and complies with the City’s Zoning Ordinance,  construction codes, and other development related laws and ordinances.

• To protect your investment and minimize liability or problems during a future sale of your property.
