What people build around Wentzville
Inside the city most lots are in subdivisions, where the rules and the covenants set the size. Past the city limits the ground opens up fast.
Garages on city lots
The 40% rule and your subdivision covenants set the size.
Acreage shops
Unfinished and under sixty feet wide, tubular steel is usually the answer.
Farm buildings
Equipment and hay storage go up on the farms west toward the county line.
Finished space
Steel truss takes drywall directly, so there’s no second wall to build.
We also work in cold-formed steel and red iron. See what a steel building costs.
Permitting in Wentzville and St. Charles County
Wentzville limits accessory buildings by the size of the house. Outside city limits, St. Charles County permits under its own 2021 codes.
Inside Wentzville
- Anything over 120 sq ft needs a permit.
- It can be no larger than 40% of the house’s total building area.
- It can be no taller than the house.
- The Building Division in Community Development handles permits.
Placement
- Buildings go in the rear yard. Only garages may go in a required front or side yard.
- They can’t sit in a transition strip or recorded easement.
- They’re secured by piers, footings or anchors.
- Check your subdivision covenants before you apply.
Unincorporated St. Charles County
- The county adopted the 2021 building and residential codes.
- The Building and Code Enforcement Division permits and inspects.
- We confirm what your parcel needs before drawings are produced.
In the city, the house sets the limit. A 2,000 sq ft house caps accessory buildings at 800 sq ft. If you want a bigger shop, it’s worth knowing whether the parcel is inside the city before you settle on a footprint.
We also serve Lake St. Louis, O’Fallon, Foristell, Flint Hill, New Melle and Wright City. See Troy, Warrenton or the St. Louis metro.
