Frequently asked questions — Miami-Dade County, Florida
What is an NOA and why does Miami-Dade require it?
A Notice of Acceptance (NOA) is Miami-Dade County's product approval certification - stricter than the statewide FL Product Approval. Windows, doors, and roofing materials must be tested to Miami-Dade's HVHZ standards. Products sold nationally at Home Depot or Lowes are typically NOT NOA approved. Search the Miami-Dade product approval database before purchasing materials.
Can the same contractor pull all my permits?
A general contractor can pull the building permit but trades (electrical, plumbing, HVAC) must be pulled by licensed trade contractors in their specialty. In Miami-Dade, the trade contractor must be registered with the county in addition to holding a state DBPR license.
How does the Substantial Improvement rule work in Miami-Dade?
If repairs or renovations exceed 50% of the structure's pre-damage value, the entire building must be brought into full current code compliance - including elevating if in a flood zone. This is critical for properties damaged by hurricanes. Miami-Dade enforces this strictly and tracks cumulative improvements over a rolling period.
Does my homeowner insurance change after a new roof?
Significantly. A new roof with a wind mitigation inspection report can reduce Miami-Dade homeowner insurance premiums by 20-50%. In the current Florida insurance crisis, this can mean thousands of dollars per year in savings. Always schedule a wind mitigation inspection immediately after roof completion.
