FLORIDA ADU · RENTAL ECONOMICS · 2026

What can you earn renting an ADU in Florida?

A Tooly rents for $1,200–$1,800 a month across Florida's major metros. On a $85,000 unit, that's a 16–31% gross yield — multiples of what most rental properties produce. Here's the math, the variability, and the realistic returns by city.

Florida ADU rent ranges (2026).

The numbers below reflect typical long-term lease rents for a furnished 1-bedroom unit similar in size to a Tooly. Short-term (Airbnb) rates are higher but more variable and increasingly restricted by city ordinance.

THE FULL ROI MATH

What you actually take home.

Gross yield is the easy number. Net cash flow is the one that matters. Here's the full stack on a $105,000 all-in Tooly build in Tampa (rent: $1,500/mo) financed at 8.5% HELOC over 20 years:

Gross monthly rent+$1,500
Vacancy reserve (~5%)−$75
Property tax (~$1,200/yr)−$100
Insurance addition−$60
Maintenance reserve−$75
Mortgage / HELOC payment ($105k, 8.5%, 20yr)−$911
Net monthly cash flow+$279

Plus appreciation on the property itself, plus principal paydown on the loan (~$370/mo in year one). The cash-on-cash return is modest in the early years; the wealth-building return (equity built per dollar invested) is significantly higher.

In a market where the ADU is paid in cash:

Gross monthly rent+$1,500
Total monthly costs (taxes, insurance, maintenance, vacancy)−$310
Net monthly cash flow+$1,190
Annual net$14,280
Cash-on-cash return on $105k~13.6%
SHORT-TERM RENTAL

The Airbnb question.

Furnished short-term rentals (Airbnb, Vrbo) typically command 50–100% more revenue than long-term leases — but with more vacancy, more management, and increasingly restrictive city rules. Many Florida municipalities have tightened short-term rental ordinances since 2023.

Our recommendation: model the deal on long-term rental rates. Treat short-term upside as bonus, not the base case. The economics still work either way.

FAQ

Common ADU rental questions.

Can my city stop me from renting out the ADU?

Most Florida jurisdictions permit long-term rentals (12+ month leases) in ADUs. Short-term (under 30-day) rentals are sometimes restricted. Some cities (notably Miami) have owner-occupancy rules — you must live in either the primary house or the ADU, but you can rent the other. Full rules here.

Do I need a business license?

For a long-term lease, usually no — you're a residential landlord under Florida statute. For short-term rental, yes — you'll need a Florida DBPR vacation rental license and likely a city/county registration.

How does an ADU affect my property taxes?

Yes, it raises assessed value and therefore property tax. Typical assessment increase: 60–80% of the build cost. Your homestead exemption still applies to the primary residence; the ADU and its land allocation can be assessed at full market rate.

What about hurricane insurance?

Tooly's concrete-and-steel construction qualifies for the best wind-mitigation discount tier in Florida. Adding an insured ADU typically raises annual home insurance by $600–$1,000 — accounted for in the math above.
