Home improvement costs in Florida.
Locally calibrated cost data for fifty trades, plus the permit rules, code gotchas, and building conditions that actually matter when you plan a project in Florida.

Cost calibration
Florida costs are right at the national average.
Florida cost data tracks the national baseline, but two state-specific factors swing budgets significantly: hurricane wind requirements add 8-15% to any exterior project, and termite/moisture damage is the #1 unexpected cost driver in older homes. South Florida (Miami-Dade and Broward) runs higher than the state average because of the High Velocity Hurricane Zone (HVHZ) code, which is stricter than the rest of the state.

Permits
Permits in Florida.
Florida enforces the Florida Building Code (FBC) statewide, with stricter provisions in the High Velocity Hurricane Zone (HVHZ) covering Miami-Dade and Broward counties. Permits are pulled at the county or municipality level. Florida licenses contractors through the Department of Business and Professional Regulation (DBPR). Homeowners can act as their own contractor for their primary residence under the owner-builder exemption, but cannot do so to sell or rent within one year.
Where to file: County building department or city building department, depending on jurisdiction. Most major counties (Miami-Dade, Broward, Palm Beach, Orange, Hillsborough) have online permit portals. Small counties may still be in-person. Plan review for new construction in HVHZ counties can take 3-6 weeks.

Code highlights
What catches DIYers in Florida.
Five code rules that show up on inspector reports more than any others. Catch them before demo day.
High Velocity Hurricane Zone (HVHZ) requirements
Miami-Dade and Broward counties enforce the strictest residential code in the country. Windows must be impact-rated or shuttered, garage doors must be wind-rated, roofs need enhanced fastening, and every exterior product needs a Notice of Acceptance (NOA) on file. A non-NOA window in HVHZ is a code violation, not just a preference.
Hurricane straps and roof-to-wall connections
Florida statewide code requires hurricane straps tying rafters/trusses to wall framing. During any re-roof or significant repair, inspectors check these connections. Pre-2002 homes often have undersized straps that must be retrofitted (~$300-$800) before the new roof can pass inspection.
Termite protection (FBC 1816)
New construction and substantial alteration require termite pretreatment with a 5-year warranty and a Form HUD-NPMA-99 termite protection certificate. Replacing wood framing without re-treating creates a permit problem and a real termite risk. Florida has subterranean and Formosan termite populations statewide.
Pool safety barrier rules
Florida Statute 515 requires self-closing, self-latching gates and a 4-foot barrier around any residential swimming pool. Alternative compliance via door alarms or pool alarms is allowed but inspectors verify which method during permit final. Replacing an existing pool fence triggers full compliance review even if the pool is old.
Flood elevation requirements
Substantial improvement (over 50% of structure value) in a FEMA flood zone requires elevating the structure to base flood elevation. This is the #1 surprise in coastal renovations. Verify your flood zone and elevation certificate before scoping any major coastal remodel.
Local building conditions
What changes in Florida.
Florida home improvement costs are shaped by four state-specific factors: hurricane wind, flood exposure, termite pressure, and year-round cooling load. Plan for them and your project comes in on budget.
Wind design speed
120-130 mph (most of state), 170 mph (HVHZ counties)
Roofs, windows, garage doors, screen enclosures all need wind-rated products. NOA-listed products are required in HVHZ. Impact-rated glazing or storm panels are required in wind-borne debris regions (most coastal areas).
Flood zones
FEMA flood zone covers most of state below 50ft elevation
Substantial improvement triggers flood-elevation requirements. Get your elevation certificate before scoping any remodel over $50K. Flood insurance impacts long-term ownership cost separately from project cost.
Termite pressure
Subterranean and Formosan termites statewide; high pressure
Pretreatment and ongoing bond protection are standard practice, not optional. New construction and substantial alteration require certified pretreatment. Budget $400-$1,200 per project for treatment work.
Cooling load and humidity
Design temp 90-95°F + 70% humidity 6+ months of year
AC and dehumidification run year-round. HVAC sizing, ductwork in unconditioned attics, and envelope sealing have outsized cost impact. Mini-split additions for sunrooms are increasingly popular but require dedicated circuits.
Soil and foundations
Sandy soil statewide; sinkhole risk in "Sinkhole Alley" central Florida
Slabs and shallow foundations are standard. Sinkhole insurance is separate from regular homeowners in affected areas. Get a Phase 1 environmental study before any major addition in central Florida.
Salt-air corrosion
Coastal homes within ~1 mile of ocean see accelerated corrosion
Stainless steel fasteners, marine-grade finishes, and corrosion-resistant fixtures cost 15-30% more upfront but last 3-5x longer in coastal conditions. Cheap hardware fails fast.
