When is a building permit required for my sign?

The addition of a sign to the exterior of a building creates a structural alteration.  Signs must be designed, constructed and mounted to comply with all provisions of all adopted life, health and safety codes and standards.  Building permits will be required on an individual basis as determined by the Building Official.  Each property owner is responsible for proper permitting, installation, and maintenance of all signs on their property.

The Missoula Municipal Code requires building permits for all ground signs over 7 feet in height (20.75.020).  Construction and erection of all signs and supporting structures must comply with the International Building Code.  A building permit ensures the work on the property conforms to current safety codes.

For additional building permit requirements and information please contact Development Services at 406-552-6630.
