Backyard Cottage Florida
Zoning, Permits & Rental Income
Florida calls them detached ADUs. Same permits, same zoning rules — and potentially $950–$2,000/month in rental income. Here’s everything you need to know.
What Florida Calls a Backyard Cottage
Florida zoning codes call backyard cottages Detached Accessory Dwelling Units (Detached ADUs). They’re standalone structures — separate from your primary home — with their own entrance, kitchen, bathroom, and sleeping area.
Under Florida SB 184 (2025), every municipality must allow detached ADUs by right in single-family residential zones. No city can ban backyard cottages outright — but each sets its own size limits, setback requirements, and design standards.
HOA restriction: Florida’s ADU laws do not override HOA deed restrictions. If your CC&Rs prohibit accessory structures or secondary dwellings, you cannot build a backyard cottage regardless of state law. Review your CC&Rs before spending anything on design or permits.
Best Florida Cities for a Backyard Cottage Rental
Two factors drive backyard cottage returns: rental rate and STR permissibility. Cities with the highest combined score:
STR currently unregulated + Space Coast aerospace workforce demand. $22K–$35K/yr gross STR or $1,100–$1,500/mo long-term.
STR explicitly allowed + FSU/FAMU/state government demand. Strong year-round occupancy, 1,200 sq ft max.
High long-term rents ($1,300–$1,700/mo) despite 30-day STR min. Tourism + tech + UCF demand.
Dense university market, free pre-approved city plans cut design cost, steady year-round demand.
Snowbird + Gulf Coast lifestyle market. Verify STR status — historically open but evolving.

How to Permit a Backyard Cottage in Florida
Verify zoning and jurisdiction
Use your city's GIS map to confirm your zoning district and that you're within city limits (not unincorporated county). Zoning determines your minimum lot size, setbacks, and whether a detached ADU is permitted by right.
Check HOA CC&Rs
Before spending anything on plans, review your HOA deed restrictions for language about accessory structures or secondary dwellings. City permits cannot override private HOA covenants.
Confirm setbacks and lot coverage
Call your city's planning department with your address. Ask for your setback requirements for a detached dwelling, your maximum lot coverage percentage, and the maximum ADU size in your district.
Hire a Florida-licensed designer
All Florida municipalities require construction drawings signed and sealed by a Florida-licensed architect or Professional Engineer. Exception: Gainesville offers free pre-approved ADU plan sets.
Submit building permit application
Submit through your city's online permit portal with: current property survey, sealed construction drawings, site plan with setback dimensions, energy compliance calculations (RESCHECK), and contractor license.
Record Notice of Commencement
Required by Florida law before construction begins. Record with your county Clerk of Courts and post a certified copy on-site throughout construction.
Inspections and Certificate of Occupancy
Schedule required inspections at each construction phase. After passing the final inspection, your city issues a Certificate of Occupancy — the cottage is now a legal dwelling unit.
Short-Term Rental Compliance for Backyard Cottages
Even in cities where STRs are permitted or unregulated locally, Florida state requirements always apply:

Frequently Asked Questions
Can I build a backyard cottage in Florida?
Yes. Florida SB 184 (2025) requires all municipalities to allow detached ADUs (backyard cottages) by right in single-family residential zones. Your lot must meet the minimum size for your zoning district and have enough room to fit the cottage within required setbacks. HOA deed restrictions can still prohibit backyard cottages — check your CC&Rs before spending on design.
What is a backyard cottage called in Florida zoning law?
Florida zoning codes call backyard cottages "Detached Accessory Dwelling Units" (Detached ADUs) or simply "Accessory Dwelling Units." Some cities use other terms: Melbourne calls them "Second Dwelling Units," some counties call them "Guest Cottages." Regardless of the name, the rules are the same: a self-contained unit on the same lot as the primary home, with its own entrance, kitchen, bathroom, and sleeping area.
How big can a backyard cottage be in Florida?
Florida SB 184 (2025) prohibits municipalities from setting ADU size limits below 1,000 sq ft. But cities can set their own caps: Tallahassee allows 1,200 sq ft, most cities fall between 800–1,000 sq ft, Fort Lauderdale caps at 600 sq ft and Palm Bay at 800 sq ft or 50% of the primary home. Your cottage must also be smaller than the primary dwelling in most jurisdictions.
Can I rent my backyard cottage on Airbnb in Florida?
It depends on the city. Tallahassee and Melbourne currently allow short-term rentals from a backyard cottage. Orlando, St. Petersburg, Fort Lauderdale, and Daytona Beach require a minimum 30-day rental or longer. West Palm Beach requires 6 months + 1 day minimum. Regardless of local rules, all STR operators in Florida need a DBPR Vacation Rental Dwelling license and must collect Florida 6% sales tax plus the applicable county Tourist Development Tax.
How much does it cost to build a backyard cottage in Florida?
A detached backyard cottage in Florida typically costs $120,000–$280,000 for a new 400–800 sq ft standalone unit. Costs are higher in South Florida (HVHZ wind load requirements add $10,000–$25,000) and lower in North Florida. Budget additionally for: Florida-licensed architect ($3,000–$8,000+), county impact fees ($3,000–$8,000+), utility connections, and site preparation. Cape Coral properties may face utility connection assessments of $10,000–$30,000+ for unassessed parcels.
What are the setbacks for a backyard cottage in Florida?
Setbacks vary by city and zoning district. A detached backyard cottage that qualifies as a full ADU typically must meet principal structure setbacks — not the looser accessory structure setbacks. Typical Florida residential setbacks: 20–25 ft front, 5–10 ft side, 7.5–20 ft rear (varies significantly by district). For example, Palm Bay requires approximately 10 ft rear and 6 ft side for accessory structures. Always verify your exact setbacks with your city's planning department before designing.
How much rental income can a backyard cottage earn in Florida?
A backyard cottage in Florida typically rents for $950–$2,000/month long-term depending on market, size, and condition. Short-term rental income (where allowed) runs $22,000–$45,000/year gross for a well-managed 1-bedroom unit in high-demand markets. Tampa Bay, Orlando, and Miami command the highest long-term rents. Space Coast cities (Melbourne, Palm Bay) offer strong aerospace workforce demand with low vacancy. University markets (Gainesville, Tallahassee) offer dense year-round demand.
