A building permit gives legal permission to start construction of a project.

For information regarding a Building, Electrical, Plumbing, Mechanical, Fire Protection or County Sewer Connection Permit, you may call the Building Regulations Division (573) 634-6410.  For commercial construction, it is often a good idea to discuss your plans with the City Building Official or a City Inspector before beginning construction. Even if it is determined a permit is not required for your particular job, the City's Building Regulations Division staff are happy to assist you with your construction inquiries and often provide valuable advice.

Permits can now be applied for through the City's Online Portal:

Permits are usually required for the following:
New Buildings - Commercial and Residential
Residential Additions (bedrooms, bathrooms, family rooms, etc.)
Residential Work (decks, garages, fences, fireplaces, pools, water heaters, etc.)
Residential Renovations (garage conversions, basement furnishings, kitchen expansions, etc.)
Commercial Additions, and Commercial Renovations (tenant finishes, office remodels, etc.)
Electrical, Plumbing, and Mechanical systems

The frequently asked questions section under "Do I need a building permit?" is very helpful.  Also, please look at the "Permit Policies and Procedures" page for additional information.

In general, City staff need to know what is construction is proposed, prior to it beginning.  The permit application process will help to document the "Who, What, When, Where and How" of the project.  This can be done with sketches or a full set of construction documents.  It just depends on what is being proposed to be constructed.

Once the proper documentation has been received and approved, the Building Official will issue a building permit giving authorization to start construction.  The applicant will then be responsible to call for inspections of the work at the appropriate times.  The applicant or their representative should call, 573-634-6410 (Mon-Fri, 8-5pm) to request site inspections.

Upon completion of all work and final inspections have been accomplished, the permit will be closed.  If the project involved constructing a new building, an addition, or a major alteration, a "Certificate of Occupancy" or "Certificate of Completion" will be issued to the permit applicant.

Please keep the following tips and hints in mind when applying for your building permit:

  • Building Permits will be null and void if construction does not begin within (6) six months of the date they are issued.
  • A Building Permit conveys no right to occupy any street, alley or sidewalk or any part thereof, either temporarily or permanently. Encroachment on Public Property that is not specifically permitted under the Building Code must be approved by the jurisdiction. The issuance of a building permit does not release the applicant from the conditions of any applicable subdivision restrictions.
  • The disposal of demolition waste is regulated by the Department of Natural Resources under chapter 260 RSMo. Such waste in types and quantities established by the department shall be taken to a demolition landfill for disposal.
