Frequently Asked Questions

Before you design or commission a sign, please refer to Municipal Zoning Code Title 20 for standards for maximum size, height, location, and number; 20.75.050 - Signs in Residential and Open Space/Public Districts and 20.75.060 - Signs in Non-Residential Districts. There are also standards for each sign type.

Please inquire at zoningdesk@ci.missoula.mt.us or (406) 552-6625 Mon - Fri 10 a.m. – 2 p.m. with any questions.

A building permit is required for ground signs above seven feet tall. Signs requiring electrical service also require electrical permitting. All signs that require electrical service shall comply with the 2012 ICC Electrical Code.

The sign permit application can be found in the online Permitting and Licensing portal. Your application will include information about each proposed sign – type, size, height, weight, and location. There should be dimensioned site plans, building elevations and sign elevations included, as well as any other drawings to demonstrate compliance. Ground signs of a certain height require structural drawings and a building permit.

When planning any sign, applicants will have to calculate the sign area. Separate measuring rules apply to each type of sign (i.e. ground, wall, etc.) See Municipal Zoning Code Title 20, 20.75.170 - Measurement Rules for information on how to measure and calculate the area of a sign.

An assigned case planner will review for any additional information required to determine a sign’s compliance.

A sign permit must be approved, paid for, and issued prior to being installed.

There is a process for requesting signs that do not comply with sign regulations. Those requests require Design Review. Please reach out to zoning desk and staff can provide details of costs and timing for that process.

All permit applications' (including sign permit applications) progress can be found in the Permitting and Licensing Portal. 

"The height of a sign is the vertical distance measured from the adjacent street grade or upper surface of the nearest street curb, but not an elevated roadway, to the highest point of the sign," see Missoula Municipal Zoning Code Title 20, Figure 20.100-17 - Terminology, Sign Height.

An engineering review is required for any signs as determined by Development Services staff, including all ground and sidewalk signs as well as any signs that are placed in and over the Right-of-Way (12.12.090). Engineering Division approval must be in place before a sign permit is issued final approval. 

For additional engineering requirements and information please contact Engineering Desk at (406) 552-6636 or engdesk@ci.missoula.mt.us.

Once a permit is issued, the sign must be installed within 180 days.

All external lighting, including fixtures that illuminate signs, require compliance with the Missoula Outdoor Lighting Ordinance.  Illumination shall maintain intensities and uniformity ratios as outlined in chapter 8.64of the Missoula Municipal Code.

All illuminated signs require an electrical permit, photometric drawing(s) and information regarding the type of lighting and light fixtures.

The Missoula Municipal Code requires the placement of sidewalk signs to accommodate a minimum 6-foot pedestrian clear zone on the sidewalk per Missoula Municipal Zoning Code Title 20, 20.75.070.I - Sidewalk Signs.

Signs that are allowed above sidewalks and other pedestrian areas must maintain a vertical clearance of 9 feet from the ground per Missoula Municipal Zoning Code Title 20, 20.75.020C.3 - Placement of Allowed Signs.

The placement of a sign has great impact on the ability of drivers to see oncoming traffic and pedestrians.  The visibility obstruction triangle is also referred to as: "clear vision area" or "the sight triangle".  This triangular-shaped area is a geometric calculation of the ability of drivers or pedestrians to tell if they can safely enter the traffic flow or cross the street. 

Signs, fences, landscaping and other obstructions within this area are limited to a specific height above the elevation of the curb or street centerline so that drivers stopped at an intersection can see oncoming traffic.  For design standards of visibility obstruction triangles see our standard drawing STD-711(Visibility Obstruction Triangle, Missoula Municipal Code 12.28.020).

All ground, sidewalk and other signs, as determined by Development Services staff, require the Visibility Obstruction Triangle to be shown on the site plan required with the application documentation. 

Engineering Division approval must be in place before a sign permit is issued final approval. 

As part of the application process, applicants must submit supplementary materials. The required documentation will include scale drawings; elevations of the proposed signs, a site plan with the signs’ locations, and building elevations.

Signs are reviewed under standards for the zoning district of the property where the sign will be posted or built. Each zoning district has different restrictions and regulations regarding the allowed number of each type of sign, as well as size, height, and illumination. (20.75.050--20.75.060)

When planning any sign, applicants will have to calculate the sign area. Separate measuring rules apply to each type of sign (i.e. ground, wall, etc.) See 20.75.170 for information on measurement rules and how to calculate the area of a sign.

The required documentation will include scale drawings; elevations of the proposed signs, a site plan with the signs’ locations, and building elevations. Required drawings are dependent on the sign type; site plans for ground signs and building elevations for wall, window or projecting signs.

There are two different types of frontages that affect signs: building frontage and property frontage.  Wall signs are affected by the building's frontage, whereas ground signs are determined based on the property's frontage.  For more detailed descriptions and guidelines please see Missoula Municipal Zoning Code Title 20 20.75.170 - Measurement Rules.

For additional information or questions please contact Zoning Desk at (406) 552-6625 or zoningdesk@ci.missoula.mt.us.

There's an old saying in the fire service, "we can't help you if we can't find you."  Proper addressing and identification is essential to fire and rescue services.

The International Fire Code requires that new and existing buildings have approved address numbers, building numbers or approved building identification placed in a position that is plainly legible and visible from the street or road fronting the property.

For additional information on requirements, standards, sizes and types of numbering and lettering please contact the Fire Department at (406) 552-6210.

The addressing of a lot or structure must be clearly displayed.  In addition to the International Fire Code, the Missoula Municipal Code has specific requirements regarding addressing.  Please see Title 12, 12.52.020 - Street Numbers for a specific requirements and guidelines. 

Addressing on all buildings is allowed without a sign permit provided such signs are not internally illuminated, cause glare, or cast light onto adjacent property per Missoula Municipal Zoning Code Title 20, 20.75.040 - Signs Allowed Without a Sign Permit.
