Frequently Asked Questions
Do I need a building permit?
The following are excerpts from the 2015 International Building and Residential Codes for work that is exempt from a building permit. It is a much shorter to list work that does not require a permit versus for work that does need a permit;
Residential Work (1 and 2 Family units)
If you still have questions, please call (573) 634-6410 and ask to talk with a building inspector.
Do I need a permit for a shed?
For residential uses, a shed 200 square feet and smaller is exempt from a building permit.
With Commercial uses, a shed 120 square feet and smaller is exempt from a building permit.
With both Residential and Commercial, please check setbacks from the property lines. With a residential lot, a shed in the backyard should be 5 feet away from the rear and side property lines if it's more than 60 feet away from the front property line.
Do I need an architect or engineer?
The following are links to copies of the Revised Missouri Statutes that define the practice of Architecture and Engineering. These also list instances of unauthorized practice prohibited - persons excepted.
