The permitting differences between Broward, Miami-Dade, and Palm Beach are real, but they are not where owners expect. The Florida Building Code applies statewide, so the structural rules are largely common. What varies is administration: which departments exist, how submittals are filed and tracked, which reviews are consolidated, and how municipalities within each county add their own layer on top.
Key takeaways
- What is actually the same across all three?
The Florida Building Code, product approval requirements, the licensing regime for contractors and engineers, and the state and federal environmental and coastal programs. - What is the high-velocity hurricane zone distinction?
The high-velocity hurricane zone is the single most significant technical difference among Broward, Miami-Dade, and Palm Beach. Miami-Dade and Broward fall within the high-velocity hurricane zone, which imposes more demanding provisions for openings, roofing, and product approval, along with additional documentation. - How does administration differ?
Administration differs across the three South Florida counties in structure and in interface. - Do the municipalities matter more than the counties?
Frequently, yes: a luxury home in a coastal South Florida municipality may face architectural review, additional height and massing rules, stricter landscape and lighting standards, and its own submittal portal, none of which appear in county guidance.
What is actually the same across all three?
The Florida Building Code, product approval requirements, the licensing regime for contractors and engineers, and the state and federal environmental and coastal programs. The permitting differences that matter are administrative and municipal, not structural, which surprises owners who expect three separate rulebooks.

What is the high-velocity hurricane zone distinction?
The high-velocity hurricane zone is the single most significant technical difference among Broward, Miami-Dade, and Palm Beach. Miami-Dade and Broward fall within the high-velocity hurricane zone, which imposes more demanding provisions for openings, roofing, and product approval, along with additional documentation. Palm Beach sits outside it, so the permitting differences there begin with a different product approval landscape.
The practical effect is covered in hurricane-resistant construction.
How does administration differ?
Administration differs across the three South Florida counties in structure and in interface. Each county operates its own building department alongside dozens of municipal departments, and a project may be reviewed entirely by a city, entirely by the county, or by both depending on where it sits. Establishing which applies is the first practical step, and it is where permitting differences most often surprise people.
Departments are at Broward County, Miami-Dade County, and Palm Beach County.
Do the municipalities matter more than the counties?
Frequently, yes: a luxury home in a coastal South Florida municipality may face architectural review, additional height and massing rules, stricter landscape and lighting standards, and its own submittal portal, none of which appear in county guidance. The most consequential permitting differences on a specific project are usually municipal.
The zoning question is covered in navigating the permitting process.
How does floodplain administration vary?
Floodplain administration varies across South Florida in freeboard and in local amendment. The base flood elevation comes from federal mapping, but the additional freeboard a jurisdiction requires above it is a local decision and it differs. Two otherwise identical parcels in different municipalities can require different finished floor elevations, which is among the costliest permitting differences to discover late.
Maps are published through the FEMA Map Service Center, with detail in base flood elevation requirements.
| Aspect | Same everywhere | Varies by jurisdiction |
|---|---|---|
| Building code | Florida Building Code applies statewide | High-velocity hurricane zone provisions |
| Product approvals | Statewide approval system | Which approvals suit the wind zone |
| Licensing | State licensing of contractors and engineers | Local registration requirements |
| Flood elevation | Federal base flood elevation mapping | Local freeboard added above it |
| Design review | No statewide requirement | Municipal and association architectural review |
| Environmental | State and federal programs | County environmental review scope |
Are the environmental reviews different?
For environmental reviews in South Florida the state and federal layers are common, but county environmental programs differ in scope and in how they coordinate with the state. Broward and Miami-Dade both operate substantial environmental review functions, and how a shoreline or dock application moves between county, state, and federal desks is one of the genuine permitting differences between them.
State programs are at Florida DEP and the South Florida Water Management District.
Does one county issue faster than another?
No South Florida county issues permits faster reliably, and treating any of them as inherently fast or slow leads to bad planning. Throughput varies with workload, staffing, and the season, and a well-prepared file moves faster in a busy jurisdiction than a poor file does in a quiet one. Preparation dominates the permitting differences in practice.
The mechanics are explained in why permit delays happen.
What should an owner establish first?
A South Florida owner should establish five things first: which department reviews this parcel, whether the municipality adds architectural or design review, what local freeboard applies, whether the high-velocity hurricane zone provisions apply, and which environmental reviews the shoreline scope triggers. Those five answers define the permitting differences for that specific project.
The checklist belongs in pre-construction planning.
How does Kass Construction & Development work across the three?
By establishing the reviewing bodies before design: Kass Construction & Development, a state-licensed (CGC1529472) boutique luxury builder headquartered in East Fort Lauderdale and led by Mitch Kass, a licensed general contractor and attorney, with 100+ luxury residences delivered by Mitchell Kass and the firms he has led across Broward, Palm Beach, and Miami-Dade, treats the permitting differences as a per-parcel question rather than a per-county rule.

What are the permitting differences across the three counties, element by element?
The permitting differences between Broward, Miami-Dade and Palm Beach are clearest in a side-by-side comparison of the elements that affect a luxury home, and the table below is that comparison.
| Element | Broward | Miami-Dade | Palm Beach |
|---|---|---|---|
| Building code | Florida Building Code with the high-velocity hurricane zone provisions | Florida Building Code with the high-velocity hurricane zone provisions; county product control program | Florida Building Code standard wind provisions with local amendments |
| Product approvals for openings and roofing | Florida product approvals tested for the HVHZ, or Miami-Dade Notices of Acceptance | Miami-Dade Notices of Acceptance commonly required | Florida product approvals |
| Who issues the building permit | Municipalities for incorporated areas; county for unincorporated | Municipalities and the county’s building department for unincorporated areas | Municipalities and the county for unincorporated areas |
| Floodplain administration | Municipal floodplain administrators; county policy on seawall cap elevations | Municipal and county floodplain administrators; county freeboard rules in unincorporated areas | Municipal floodplain administrators; coastal municipalities with their own freeboard |
| Environmental and shoreline review | County Environmental Engineering and Permitting Division license for work at or below mean high water | County Division of Environmental Resources Management Class I permits for coastal work | County Environmental Resources Management review with municipal permits |
| State and federal layers | Florida DEP submerged lands and CCCL; Army Corps for navigable waters | Same | Same, with CCCL interaction along the barrier islands |
| Design and historic review | Municipal boards in some cities | Municipal boards; historic districts in several cities | Municipal architectural review common in coastal towns |
| Portals and tracking | Varies by municipality | County online system plus municipal systems | County online system plus municipal systems |
The code is published by the Florida Building Commission, flood zones by FEMA, and state environmental programs by the Florida Department of Environmental Protection with regional water rules from the South Florida Water Management District. The structural consequences of the HVHZ are explained in hurricane-resistant construction and building codes across Palm Beach, Broward and Miami-Dade.
What should an owner establish first on a parcel in any of the three counties?
The permitting differences matter less than the five facts an owner should establish for a specific parcel, and the sequence below produces them before design money is spent.
- Which department reviews this parcel: the municipality or the county, and which portal and checklist it uses.
- Whether the parcel lies in the high-velocity hurricane zone, which decides the product approvals and the structural design.
- The flood zone, base flood elevation and the local freeboard for that municipality, which set the finished floor; see base flood elevation requirements and luxury living in VE zones.
- Whether any shoreline, submerged land or CCCL review applies, and which county environmental agency leads it.
- Whether design review, historic review or a homeowners association approval sits in front of the building permit.
- The municipality’s current review times and comment-cycle norms, which set the calendar in the South Florida custom home permitting timeline.
- Any county or municipal seawall cap elevation minimums, which shape the site plan on waterfront lots.
How does a builder work across the three counties without losing time?
The permitting differences are manageable for a builder that keeps a current map of each jurisdiction, and the practices below are what make a tri-county practice run on one standard.
- A jurisdiction file for every municipality: contacts, portal, checklist, review times, local amendments and quirks, updated after every project.
- Product specifications written to the strictest standard, so a window package approved for Miami-Dade works anywhere in the region.
- Survey and flood documentation ordered to the most demanding reviewer’s format.
- Shoreline applications opened first in every county, since the state and federal layers are common and slow, per permit delays on South Florida luxury homes.
- A pre-application meeting wherever the municipality offers one, before schematic design.
- One person owning each file with weekly status, as described in navigating South Florida’s permitting process.
- Preparation folded into pre-construction planning so the differences are known before they can cost time.
Kass Construction & Development builds across Broward, Palm Beach and Miami-Dade and treats each municipality as its own jurisdiction with its own file, so the permitting differences are planned rather than discovered.
Frequently Asked Questions
What are the main permitting differences between the three counties?
Administration rather than code: which department reviews the parcel, what the municipality adds, local freeboard, whether high-velocity hurricane zone provisions apply, and how environmental review is coordinated.
Is the building code different?
No. The Florida Building Code applies statewide. The high-velocity hurricane zone provisions apply in Miami-Dade and Broward but not Palm Beach.
Does the city or the county review my project?
Where the parcel sits decides it. It may be the city, the county, or both, and establishing this is the first practical step in any project.
Why do finished floor elevations differ?
Base flood elevation is federal, but the freeboard added above it is a local decision and varies by jurisdiction, so identical parcels can require different elevations.
Which county is fastest?
None reliably. Throughput varies with workload and season, and a well-prepared file outperforms a poor one in any jurisdiction.
Do municipalities add much?
Often more than the county does: architectural review, height and massing rules, landscape and lighting standards, and separate portals.
What should I confirm first?
The reviewing department, any municipal design review, local freeboard, whether the high-velocity zone applies, and which environmental reviews your shoreline scope triggers.
