Homestead FAQ
Do I need a permit to regrade my Homestead property?
Significant grading, fill placement, and drainage modifications require permits. Minor landscaping adjustments may be exempt. Contact the Building Department at (305) 224-4400.
Can I add fill to raise my Homestead lot?
Fill placement requires approval and clean, compatible material. Adding fill does not change your flood zone designation — you need a FEMA LOMA for that.
My neighbor's runoff floods my Homestead property. What can I do?
Unpermitted drainage modifications that redirect water to neighboring properties are code violations. File a complaint with Code Compliance at (305) 224-4800. You may also have civil remedies.
Miami FAQ
Why is drainage so important in Miami?
Miami's extremely low elevation, high water table (often 3-5 feet below surface), and limestone geology create unique drainage challenges. Proper drainage design is essential for all development.
Do I need a permit to fill or grade my lot?
If your property is in a flood zone, you need a Floodplain Development Permit. All development requiring building permits must include drainage plans showing compliance with city standards.
