Best ADU Builders in FloridaFlorida's Most Comprehensive ADU Builder Directory — 2026
Before you hire anyone: confirm your address qualifies. Then choose from Florida's top-vetted ADU contractors — organized by region, project type, and budget.
Who are the best ADU builders in Florida?
Florida's best ADU builders in 2026 are Mesocore (statewide modular specialist, HVHZ-capable), TEK Construction Group (Central FL, 50+ completed ADUs), Goshen Tiny Homes (compact custom units, Orlando area), Mint Builders LLC (luxury custom ADUs), and W. Robbins Construction (budget-friendly, Orange County Ready Set Orange program). Before contacting any builder, use ADU Florida Info to confirm your parcel's zoning eligibility — Florida's rules vary significantly by city and county.
Check your specific parcel before contacting builders
Florida ADU eligibility is parcel-specific — not just city or county. Some zones prohibit ADUs entirely; others require minimum lot sizes, owner occupancy, or cap ADU size as a percentage of the primary structure. Hiring a builder before confirming eligibility wastes design fees and deposit money. Check your address free in 30 seconds →

Best Garage Conversion
Local GC with ADU permit history
Garage conversions are the most affordable ADU type ($40K–$80K) but vary enormously by contractor quality. Always verify permit history before hiring.
What to Look for in a Florida ADU Contractor
Florida DBPR license and local permit history
Any ADU contractor must hold a current Florida DBPR Certified General Contractor or Residential Contractor license. More importantly: verify they have pulled permits in your specific city or county — not just somewhere in Florida. ADU permit requirements differ significantly between, say, Tampa and Hillsborough County unincorporated, or City of Orlando and Orange County.
Verifiable ADU completions — not just GC experience
Ask for 3–5 addresses of ADUs they have completed in your jurisdiction within the past 18 months. Look up permit status on your county's public portal to confirm the permits were issued and received a Certificate of Occupancy. A builder who cannot produce this has not done as many ADUs as they claim.
Fixed-price contracts in writing
In Florida's volatile construction market, fixed-price contracts protect you from material cost escalation mid-project. Cost-plus contracts can balloon 20–40% above initial estimates. Get a fixed-price contract in writing before paying any deposit. TEK Construction Group and Mesocore both offer fixed-price contracts.
Knowledge of city vs. county jurisdiction
Many Florida addresses fall under county unincorporated jurisdiction, not city jurisdiction — and the two often have different ADU rules, setback requirements, and permit offices. A builder who does not immediately know which jurisdiction governs your parcel has not worked in your area extensively. This single question screens out inexperienced contractors faster than anything else.
HVHZ compliance for South Florida projects
South Florida addresses in Miami-Dade and Broward counties fall under High Velocity Hurricane Zone (HVHZ) requirements — the strictest building code in the continental US. Any contractor building there must be experienced with HVHZ specifications. Mesocore explicitly engineers for HVHZ; verify this requirement with any contractor before signing in South Florida.
Frequently Asked Questions
Who are the best ADU builders in Florida?
Florida's best ADU builders in 2026 include Mesocore (statewide modular specialist), TEK Construction Group (Central Florida, 50+ completed ADUs), Goshen Tiny Homes (compact custom units), Mint Builders LLC (luxury custom ADUs), and W. Robbins Construction (budget-friendly, Orange County Ready Set Orange program). Before contacting any builder, confirm your parcel's zoning eligibility at ADU Florida Info — rules vary significantly by city and county.
How much does an ADU cost to build in Florida?
ADU construction in Florida costs $100–$200 per square foot in 2026. A standard 600 sq ft detached ADU runs $130,000–$260,000 all-in (construction, permits, impact fees, utility connections, site work). Garage conversions cost $40,000–$80,000. Modular ADUs (Mesocore) run $90,000–$180,000 installed. Impact fees and utility connection costs vary widely — Cape Coral adds $10,000–$30,000 in utility assessments alone.
Do I need to check zoning before hiring an ADU builder in Florida?
Yes — this is the most important step before contacting any builder. Florida ADU eligibility depends on your specific parcel's zoning district. Some zones prohibit ADUs entirely; others require minimum lot sizes, owner occupancy, or cap ADU size relative to the primary structure. Use ADU Florida Info to verify your address in 30 seconds before spending any money.
Which Florida cities are best for ADU investment?
Tallahassee is currently Florida's most ADU-friendly city after a 2024 reform allowing 1,200 sq ft ADUs by-right citywide with STR permitted. Gainesville offers a free pre-approved plans program. St. Petersburg allows parking waivers near transit corridors. West Palm Beach is most restrictive — ADUs limited to SF14 zoning only. Orlando and Tampa have the largest established builder markets.
Can I rent out my ADU in Florida?
Yes — Florida law (SB-48, 2023) prohibits local governments from banning ADU rentals statewide. Long-term rentals (12+ months) are allowed in all Florida cities. Short-term rentals (Airbnb/VRBO) are regulated at city level — Tallahassee and Gainesville permit them; Daytona Beach prohibits ADU STRs. Most cities are in a grey zone. Verify your specific city's STR ordinance before building with rental income as the investment thesis.
What is the best modular ADU builder in Florida?
Mesocore is Florida's leading modular ADU builder in 2026. They build permanent, hurricane-engineered units with HVHZ compliance, offer turnkey Design → Permit → Build service with permit-ready plan sets, and install completed units significantly faster than stick-frame construction. Their units qualify as permanent structures for appraisal purposes.
What is Florida SB-48 and how does it affect ADU builders?
Florida SB-48 (2023) is the statewide ADU preemption law. It prohibits local governments from banning ADUs on single-family lots, banning ADU rentals, or requiring owner occupancy as a condition of permitting an ADU. This dramatically expanded where ADUs are legal in Florida. However, SB-48 does not override local zoning districts — cities can still require specific zoning classifications, minimum lot sizes, and setbacks. See our full SB-48 guide for details.
