The Department is dividing into two interrelated divisions.

  • Guiding and facilitating development projects within the City of Clayton

  • Scheduling and conducting building inspections

Current News/Updates

The City of Clayton has always prided itself in offering high quality housing opportunities. In order to assure that new construction meets high quality standards and is in general conformity with the style and design of surrounding structures, the Architectural Review Board considers all exterior components. As part of this review and approval process, there are several criteria including, but not limited to, types and quality of materials, landscaping, design and compatibility with adjacent structures. Redevelopment of residential properties has accelerated dramatically in virtually all neighborhoods over the past several years. It is important to assure that the quality of construction remains at a high level. If you are making any type of changes to the exterior of your house including driveway replacement, landscape removal, hardscape additions, window replacement, exterior finish change, etc. please contact the City's Planning Department BEFORE you select a contractor to determine if the changes you propose meet the Architectural Standards and other applicable codes and if the work you are doing requires a permit.

Subdivision Indentures

We get a lot of Questions about Subdivision Indentures. Here is some information that may help you. Click here.

Carbon Monoxide Alarm Requirement

The 2015 International Residential Code requires carbon monoxide alarms in new one and two family dwellings and in existing one and two family dwellings when work requiring a permit takes place. The carbon monoxide alarms must be installed in the immediate vicinity of all sleeping areas. Hardwired, battery operated or plug-in alarms may be used. Unlike the smoke alarm requirements, there is no exception for exterior work or the addition of decks or porches. Roofing, siding, window replacement and other exterior work requiring a permit will require the installation of carbon monoxide alarms. Click here to view a summary of the requirements

Rodent Control

Clayton does not administer a rodent control program; rodent control is the responsibility of the property owner. Section 308.1 of the City Building Codes and Building Regulations requires that all structures be kept free from rodent infestation. For control methods to be effective, all residents must do their part and work together to keep our neighborhoods free of rats. If you have any questions, please call Clayton Building Inspections at 314-290-8455 or St. Louis County Vector Control at 314-727-3097 or visit St. Louis County Rodent Control Information.
