Safety Harbor FAQ
Do I need a permit for a small landscape retaining wall?
Short decorative walls under a few feet may be exempt, but check with the Building Division first. Anything taller or holding back significant soil typically requires a permit.
Can I put a fence on top of my retaining wall?
Yes, but the combined height of the wall plus fence is generally counted against the maximum fence height for that yard under Safety Harbor's Land Development Code.
St. Petersburg FAQ
Do I need a permit for a retaining wall in St. Petersburg?
Walls retaining over 4 feet of fill, or any wall with a surcharge load, require a permit and engineered plans. Smaller decorative walls usually do not need a permit.
Can a retaining wall affect my fence height?
Yes, the city measures combined fence and wall height from natural or finished grade for purposes of Section 16.40.040, so a tall wall plus a fence can exceed the 6-foot limit.
