Building and Permits

The Building Division performs plan review and inspections on new residential and commercial properties. Residential permits are required for any new home, as well as for decks, sheds, pools, basement finishes, additions and major alterations. Residential rental occupancy permits are required before occupying the unit. Commercial permits are required for any new commercial project including alterations or additions. This division is also responsible for the planning and implementation of the City’s adopted building codes and ordinances.

The division is located on the second floor of O'Fallon Municipal Centre (City Hall). Hours of operation are Monday through Friday, 8 a.m. – 5 p.m.

You may schedule an inspection online by clicking this link, or call 636-379-5595. Any inspection request received prior to 4 p.m. will be placed on the inspection list for the following business day, unless otherwise specified.

Inspections are performed typically between 8:30 am—3:30 pm Monday Thru Friday (with the exception of Holidays) and are subject to change. Emergencies or other unpredictable events arise that may affect the day’s schedule or the amount of time required to complete an inspection. This listing is to be used as a guide only.

Below is a list of building permit applications currently under review. While we strive to complete reviews as quickly as possible, applicants should be aware the process can not be guaranteed a specific turnaround time. Reviews are generally undertaken in order received. Please be aware of delays which may exceed the normal plan review time such as other department approval processing, additional information required or various other situations that may arise. Once the permit is approved and available for payment they will be dropped from this list. If you have any questions please contact the Building Division at 636-379-5660.
