Clarksville has no chapter devoted to retaining walls. The zoning ordinance exempts them from the corner sight-triangle height limit, the drainage chapter exempts their excavation from grading permits, and structural review runs through the adopted building code.
A full-text sweep of the Clarksville code and zoning ordinance turns up retaining walls in only two operative places. Zoning Ordinance Sec. 4.1.1 caps vision-impeding fences, walls, structures and vegetation in the corner sight triangle at three and one-half feet, then carves out retaining walls from that limit. City Code Sec. 12-304 exempts finish grading or excavation below finished grade for retaining walls, swimming pools and cemeteries from the grading permit that otherwise attaches to land disturbing activity. Structural requirements come from the 2018 International Building Code and 2018 International Residential Code adopted at Sec. 4-201 and Sec. 4-801. The city publishes no separate wall height threshold in ordinance form.
Building without a required permit is enforced by Building and Codes under the adopted codes, which set a fifty dollar civil fine with each day a separate offense.
