Do I need a permit?

According to the St. Louis County Department of Public Works, in the county of St. Louis you’re required to have a permit for all sheds larger than 120 square feet in area. If your shed exceeds 400 square feet and/or has a proposed roof eave height of greater than 10 feet, it should be designed following the Residential Detached Garage Building Permit Requirements, which can be found here. If you do need a permit, it’s important to keep in mind that there is a charge for each permit, generally determined by the cost of the project itself. Depending on your municipality, this fee may be collected when you submit your application or when the permit is issued.  In some areas, a small fee will be charged for submission and the rest at the time the permit is issued.

Contact your municipality

The first thing you’ll need to do is determine whether you need to apply for a permit through your city or your county government. A majority of the municipalities within the county of St. Louis process permits themselves, while others contract with the county to handle part of or all of the permit process. There are certain cases as well where you’ll need to get approved by the zoning department in your municipality and then get approved by the county for your structure. So, the first step you’re going to want to take is to contact your municipality and find out whether or not they handle the permitting for your building. The best place to start is your municipality’s building department or public works.  They should be able to answer any questions you have.

Extra tip: This might also be a great time to find out what the setback requirements for your property are. A setback is the distance you must maintain between the property line and the accessory structure. It’s generally not consistent within a municipality or county, but rather is determined by how your lot is zoned.

What next?

Gather your information

Once you know where you’ll need to file for your permit, it’s time to gather up all of the applicable information that you’ll need. For most municipalities, you’ll be able to find exactly what information you’ll need on their website. Since there are over 90 municipalities in St. Louis county, it’s incredibly important that you contact the correct one. Here’s an example of what will be required if you need to submit your permit to the St. Louis county rather than to one of the municipalities. Most municipalities will go by the same code, however, there may be specific restrictions or additions to these codes which you’ll be required to follow. You will also be required to create detailed building construction plans drawn to scale, such as this example from the St. Louis county.


Extra tip: A great resource you could use during this process is your county’s Geographic Information System (GIS). You should be able to find your property in your county’s GIS. You’ll be able to find a ton of great information there and you’ll be able to create a plot of your property using the GIS system. Here is the link to the St. Louis county GIS to help you on your way!

Submitting Your Permit

Once you’ve contacted your municipality, determined what information you’ll need and gathered it, then you’re ready to submit your permit for approval. Some, but not all, municipalities in the St. Louis county allow you to submit your permit application electronically. It’s more likely that you’ll have to submit your permit application in person, or through the mail. Generally speaking, you should expect feedback on your application in 7-10 business days. In some cases, you may be approved but will also be “red lined”. This simply means that while you’ve been approved there has been an indication from the plan reviewer that something in the documents you submitted did not meet specifications and must be addressed as the project is being completed.

Once you’ve received the green light for your project, you can start at any time you please. Keep in mind that depending on the building type and size, there will be an appropriate inspection schedule put in place. It’s incredibly important to follow this schedule in order to avoid fines or having to take things apart to ensure the governing body can inspect them. Once the final inspection takes place, you’re finally finished with the process! Be sure to keep all of your documents pertaining to the project on file just in case any questions are brought up down the road.
