Key ADU Restrictions in Kissimmee
These are the rules that most often catch homeowners by surprise. Read them carefully before engaging an architect.
- Kissimmee's tourism corridor and residential zones have different STR rules — confirm your parcel's zone before designing for vacation rental
- Osceola County requires separate STR license for vacation rental use — this is in addition to city building permits
- Flood zone compliance required for parcels near lakes and wetlands — significant portions of Kissimmee are in FEMA flood zones
Common Mistakes to Avoid in Kissimmee
- Assuming Disney-area STR is automatically permitted — many Kissimmee residential zones prohibit commercial vacation rental use
- HOA restrictions in most Kissimmee master-planned communities prohibit STR even when city/county allows it
- Flood zone designation can require elevated ADU construction — check FEMA map before finalizing design
Eligible Zones in Kissimmee

Kissimmee ADU — Frequently Asked Questions
These are the questions we hear most often from Kissimmee homeowners. If yours isn't here, our ADU Zoning Experts can answer it directly.
Can I run a short-term vacation rental out of a Kissimmee ADU near Disney?
Yes, if your property is outside an HOA that prohibits it. Kissimmee and Osceola County have one of Florida's most active STR markets due to proximity to Disney World, Universal, and other theme parks. You need Osceola County STR registration, a Tourist Development Tax (TDT) collection agreement, and a City of Kissimmee Business Tax Receipt. STR income near Disney can run $80–$200/night.
Is my address in the City of Kissimmee or Osceola County unincorporated?
This is critical — City of Kissimmee and Osceola County unincorporated areas have separate permit processes and zoning codes. Look up your parcel at the Osceola County Property Appraiser website (pa.osceola.fl.us) — the jurisdiction field will show 'City of Kissimmee' or 'Unincorporated Osceola.' Unincorporated parcels apply through the Osceola County Growth Management department.
What are the most common ADU zones in Kissimmee?
The most common residential zone in Kissimmee is R-1A (Single-Family Residential). R-2, R-3, and RP (Residential Planned) zones also permit ADUs. Properties in Planned Unit Developments (PUDs) need to check their specific PUD ordinance for ADU provisions. Call Kissimmee Building at (407) 518-2100 to confirm your zone's ADU eligibility before designing.
Is Kissimmee in the Hurricane Wind Borne Debris Region?
Kissimmee is in Central Florida, inland from the coast. While not in the HVHZ, Kissimmee is in the Wind Borne Debris Region per Florida Building Code (FBC) for properties in higher wind speed zones. This requires impact-resistant windows and doors or approved storm shutters in new construction. Costs are lower than coastal HVHZ markets but higher than some inland areas.
What is the land availability situation for ADUs in Kissimmee?
Kissimmee has a mix of older single-family neighborhoods (many with large lots suitable for detached ADUs) and newer master-planned subdivisions (often with smaller lots and HOA restrictions). The older neighborhoods near Downtown Kissimmee and along US-192 generally have larger lots and no HOA. These areas are ideal for detached ADU construction and offer good access to the tourism employment corridor.
