Existing Businesses

Interior Improvements

If you plan to make physical improvements to the inside of your existing business (i.e. add partition walls, restrooms, electrical connection, etc), you may need to secure a permit first. Contact the Building Division at 314-385-3300 to determine if a permit is required. Depending on the extent of the proposed improvements, approvals from outside agencies such as the Northeast Fire Protection District or St. Louis County may also be required.

Exterior Improvements

If you plan to make physical improvements to the outside of your existing business, you may need to secure design review approval and/or permits first. Contact the Planning Division for the level of design review that may be required.

Depending on the extent of the proposed changes, one of the following levels of design review will apply:

  • Administrative Staff review (very minor alterations only)
  • Architectural Review Board Subcommittee review (minor alterations)
  • Architectural Review Board review (major alterations)

Also contact the Building Division to determine if a Building Permit (PDF) is required for the exterior improvements.
