Sarasota County ADU — Frequently Asked Questions
The most common questions from Sarasota County homeowners about ADU rules, permits, and costs.
How do I know if my Sarasota address is in the City or in Sarasota County?
This is the most important question for Sarasota ADU planning. Look up your parcel at the Sarasota County Property Appraiser (sc-pa.com) — the jurisdiction field will show 'City of Sarasota' or 'Sarasota County.' The City of Sarasota is a relatively compact urban area. Most beach communities (Siesta Key, Venice, Osprey) are outside the city. The rules are fundamentally different — city allows STR (7-day min), county bans STR under 30 days.
How big can an ADU be in the City of Sarasota?
The City of Sarasota caps an accessory dwelling unit at 650 sq ft, up to 24 feet tall, and it must sit at least 6 feet behind the primary home (Zoning Code §VII-602). An older 500 sq ft figure that circulated was an outdated Sarasota County number and does not reflect the current city rule. Florida has no statewide ADU size law — SB 184 (2025) and SB 48 (2026) both died — so the city ordinance controls. Confirm the current requirement with City Development Services at (941) 263-6858 before designing.
Who are the typical tenants for a Sarasota ADU rental?
Sarasota has an unusually diverse and high-earning tenant base: arts sector professionals (Sarasota Opera, Florida Studio Theatre, The Ringling), Sarasota Memorial Hospital and physician practice employees, financial professionals (several wealth management firms have Florida offices in Sarasota), retirees relocating to the area on long-term leases, and seasonal snowbirds (November–April). This drives rental income of $1,800–$3,200/month for well-finished ADUs.
What is the Vacation Rental Certificate in the City of Sarasota?
The City of Sarasota requires a Vacation Rental Certificate for any rental of less than 30 days. The certificate requires an inspection, proof of owner or manager contact information, and an annual renewal fee ($300–$500). Once certified, you can operate STR on Airbnb and VRBO in the city. The 7-day minimum stay applies. Note: Sarasota County (unincorporated) does not offer this — STR under 30 days is banned in the county.
Is Sarasota County's owner-occupancy requirement strictly enforced?
Yes. Sarasota County's owner-occupancy requirement for ADUs in unincorporated areas is an active zoning condition, not just a suggestion. A non-owner-occupant who builds an ADU in unincorporated Sarasota County may be unable to legally rent the primary residence if they leave. This restriction makes county properties significantly less investor-friendly than City of Sarasota properties. Confirm jurisdiction before purchasing a property intended for ADU investment.
