Florida's Stalled ADU Bill: What the Permit Data Says Now

The Reform That Almost Happened

Florida came within one House vote of making accessory dwelling units legal everywhere. Senate Bill 48 sailed through the Senate 38–0 in early 2026, proposing to mandate by-right ADU approval in every single-family zone across the state. No public hearings. No neighborhood veto power. Just code compliance and a standard review.

Then it stalled on the final day of session over a single provision: whether cities could ban ADU listings on Airbnb. The Senate said yes, the House said no, and rather than hold up the broader housing package, lawmakers dropped ADUs entirely.

But here's what didn't change: Florida homeowners are building ADUs — granny flats, carriage houses, garage conversions — at a steady and growing clip. We pulled five years of permit data to see where the action is, who's approving fast, and where projects sit in limbo for months. If you're bidding ADU work or selling into this market, this baseline matters.

What the Five-Year Trend Shows

Florida ADU addresses climbed 68% from 2021 to 2025. That's not just a legislative tailwind or a coastal hot market — it's real, recurring permit activity spread across dozens of jurisdictions.

Annual ADU Address Totals:

• 2021: 1,256
• 2022: 1,386 (+10%)
• 2023: 2,078 (+50%)
• 2024: 1,769 (−15%)
• 2025: 2,113 (+19%)

The 2023 spike traces directly to Hurricane Ian rebuilding in Southwest Florida. Cape Coral and Fort Myers accounted for a disproportionate share of that volume, and when you see a 50% year-over-year jump, it's not organic demand alone — it's disaster recovery layered on top.

The 2024 dip reflects broader Florida construction cooling: higher insurance premiums, slower migration, absorption of 2022–23 supply. Then Hurricane Milton hit in October 2024, and the same Gulf Coast markets that were still rebuilding from Ian took another hit. The 2025 recovery to a new all-time high says the underlying trend held.

What you're seeing is a baseline before statewide reform kicks in. ADU volume has been running 1,300 to 2,100 addresses per year, and it's climbing.

Where the Volume Is

Cape Coral is not just the leader — it's nearly half the state. Over five years, it logged 3,433 ADU addresses. That's 40% of statewide volume in our dataset from one jurisdiction.

But the rest of the map is more interesting than the Cape Coral headline.

Top ADU Markets (2021–2025):

• Cape Coral: 3,433
• Pinellas Park: 619
• New Smyrna Beach: 498
• Largo: 406
• Hillsborough County: 363
• Walton County: 266
• Sanibel: 218
• Melbourne: 211

New Smyrna Beach doesn't get enough attention. It's posted 90 to 130 addresses every year, quietly and consistently, in a market that rarely makes housing headlines. Largo jumped in 2024 and held strong in 2025, suggesting the market is opening up. Pinellas Park remains the Tampa Bay area's steadiest ADU performer.

Hillsborough County, the jurisdiction that includes unincorporated areas around Tampa, added 363 addresses over five years. Tampa itself contributed another 104. Combined, that's nearly 470 ADU addresses in the Tampa metro — one of the most active regions in the state outside of Cape Coral.

For contractors and suppliers: if you're chasing ADU work, these are the jurisdictions with proof of concept. Pinellas Park and Hillsborough move permits. New Smyrna Beach has durable demand. Largo is accelerating.

The Approval Time Gap That Reform Would Close

This is where the case for SB 48 goes from abstract policy to concrete dollars.

Median approval times across Florida jurisdictions range from 2 days to 347 days. That's not a typo. Escambia County can turn an ADU permit in 48 hours. St. Petersburg takes nearly a year.

Fastest Approvals:

• Escambia County: 2 days
• DeSoto County: 8 days
• Winter Park: 10 days
• Longwood: 13 days
• Pinellas Park: 14 days
• Walton County: 16 days

Slowest Approvals:

• St. Petersburg: 347 days
• Seminole County: 250 days
• Surfside: 93 days
• Maitland: 70 days
• Pembroke Pines: 57 days

Pinellas Park and Walton County show what a functional pipeline looks like: fast approvals and solid volume. St. Petersburg shows the opposite — a structural bottleneck in a relatively active market.

For builders, the math is simple. A 14-day approval in Pinellas Park versus a 347-day approval in St. Pete changes your carrying cost, your pipeline, and your ability to bid competitively. That 174x gap is exactly what by-right ADU approval would eliminate.

What ADU Types Are Getting Built

Not all ADUs are the same project. Florida permits span a range of configurations:

• Detached ADUs: standalone structures in the backyard, typically 400–1,200 square feet
• Attached ADUs: additions to the main house with separate entrances
• Garage conversions: the most cost-effective path, often $60,000–$150,000 all-in
• Junior ADUs (JADUs): carved out of existing interior space, usually under 500 square feet

Garage conversions dominate the affordable end. Detached ADUs run $150–$300 per square foot depending on finish level. A well-executed one-bedroom ADU in Tampa Bay rents for $1,200–$1,800 per month, which pencils for many homeowners over a multi-year hold.

But not every ADU is an income play. A large share are built for family use: aging parents, adult children, multigenerational living. AARP backed SB 48 specifically because granny flats solve a housing need that has nothing to do with rental yield.

What Reform Would Mean for Homeowners

Right now, whether you can build an ADU in Florida depends entirely on local zoning. Some jurisdictions allow it. Many don't. Some require public hearings. Some impose owner-occupancy mandates that disqualify second-home owners or investors.

SB 48 would have removed those barriers statewide. If your plans meet code, you get a standard review. No discretionary approval. No neighborhood meeting. No homestead exemption risk.

For homeowners who want to build but can't under current local rules, that's the ballgame. The bill didn't pass, but the demand didn't go anywhere. If similar legislation returns in 2027 — and it's widely expected to — this baseline becomes the before snapshot.

What Reform Would Mean for Contractors

From a builder's perspective, statewide by-right approval would shift the geographic distribution of ADU work. Right now, volume is concentrated in a handful of permissive jurisdictions. Reform would open up every single-family zone in Florida.

That doesn't mean demand materializes overnight in every market. Construction costs don't drop just because zoning changes. The economics still need to work. But in high-demand markets where housing is already constrained — think Jacksonville, Orlando, Tampa, Miami suburbs — removing the zoning barrier is enough to unlock projects that are penciling but stuck in approval.

For contractors who already work in Pinellas Park, Largo, or New Smyrna Beach: you have proof of concept. For contractors in slower-approval markets like St. Pete or Seminole County: reform would compress your permit timelines and let you move more projects per year.

For suppliers: ADU construction uses the same product mix as small residential builds. Framing, windows, HVAC, electrical, plumbing. If Florida ADU volume doubles post-reform, that's real incremental demand in established neighborhoods, not just greenfield subdivisions.

The Short-Term Rental Fight That Killed the Bill

SB 48 didn't die because lawmakers opposed ADUs. It died because the Senate wanted to let cities ban short-term ADU rentals and the House refused to include that provision.

The irony: both sides agree ADUs should be easier to build. The fight was over whether a homeowner who builds one can list it on Airbnb. That's a real policy question in Florida, where short-term rental regulation is contentious, but it's not an ADU question.

The bill will return. The 38–0 Senate vote makes that clear. This isn't a partisan issue. It's a housing supply issue, and Florida's rental market pressure isn't easing.

What Happens Next

Florida ADU permit activity is running at 1,300 to 2,100 addresses per year, and the trend is upward. A handful of jurisdictions are doing most of the work. Approval times vary by 174x depending on where you pull the permit. Statewide reform would compress that gap and broaden the map.

SB 48 stalled, but the legislative momentum is real. Similar bills are expected in the 2027 session. When reform does pass, the permit data we're tracking now becomes the baseline you'll measure against.

For contractors, this is the moment to get familiar with which jurisdictions move permits and which don't. For suppliers, it's time to map where ADU activity is clustered and where it's likely to expand. For homeowners, it's worth watching whether the 2027 session delivers what the 2026 session didn't.
