Do I need a permit for retaining wall construction in Oakdale?
Oakdale does not issue residential building permits. Oakdale opted out of Tennessee's state residential building codes and enforcement by a two-thirds vote of its legislative body, so no residential building permit is required. Owners can still ask the State Fire Marshal's Office for a voluntary permit and inspection, and electrical, zoning, and septic permits may still apply.
The requirements below come from Tennessee rules and describe the standard the work must still meet. They are not a statement that Oakdale will issue you a permit.
It depends. Whether retaining wall construction needs a permit in Oakdale comes down to the details of your project.
Tennessee's state residential permit covers new homes and additions of 30 square feet or more of interior space. Its definition of construction excludes excavation and site preparation, so the state program does not permit retaining walls. Where your city or county enforces its own code, its height limits and engineering rules apply. Walls that hold up a driveway, slope, or building often need an engineered design. The State Fire Marshal notes that a state building permit is not grading or fill approval or a flood plain determination, so ask your local office about grading, drainage, and flood rules.
