If you want to replace existing business signs with new signs, a Sign Copy Change Permit (PDF) is required by City Hall. This applies if the existing signs were legally installed with permits and the new signs comply with the City’s Sign Code (PDF), the Sign Copy Change Permit can be issued over the counter.
Banners are typically prohibited signs in Normandy, except that banners may be permitted at the opening of a new business or for promotional events with prior approval of a Banner Permit from City Hall. Banners may only be approved for a total period not exceeding 30 days if the business is new and does not have an existing business identification sign; or not to exceed 10 days within any 90-day period for temporary promotional events. Banners cannot exceed twice the allowable sign area for building attached signs permitted for the business frontage.
Other prohibited signs include:
Balloons or other gas-filled figures
Posters attached to utility poles, trees, fences, etc.
Portable signs such as sandwich boards or A-frame signs except:
Temporary real estate open house signs
Flags (other than those of the United States of America and the State of Missouri)
