Getting a permit for a detached garage in Missouri can be complicated because the submission process and codes are different based on county and not the state. If you're looking to get a permit, consider the questions before taking that first step.

A Brief Guide to Missouri Detached Garage Building Permits

Do I need a permit in Missouri?

Yes, you need a permit if you build any outside structure or add on to your property. This includes but isn't limited to garages, detached storage sheds, swimming pools, roofing, gas lines, hot tubs, or mobile homes.

Do different counties have different requirements for a permit?

Yes. The local county governs Missouri building permits, and there is no statewide standard. Codes are designated by either a six or three-year cycle, and there are some similarities in building codes shared with surrounding counties. Boone County is one of those exceptions that use the standard set in 2010. To learn your specific set of regulations, start with looking for the city and county you are located in.

What should I submit to get a building permit?

When submitting paperwork for your permit, you only need to focus on garage specific information as well as your personal information. For Boone County, make sure that you include everything from the square footage of the new structure to the size of your property. These are crucial pieces that need to be included, or the permit may not be issued, which means the project can be delayed.

How far in advance should I apply?

Twenty-four hours is required for the initial processing of your permit. You should apply at least two weeks before your project begins. During the time you're waiting for the permit to go through, an inspection will take place of the premises. Don't build before your permit is issued to you because if the permit falls through, you will need to tear the structure down. The permit stays active for a total of six months.
