How Kissimmee Handles Accessory Structures: A Practical Guide
Kissimmee maintains 112 local ordinances across all categories, and 3 of those deal specifically with accessory structures. Here is a breakdown of what the city actually requires, what is prohibited, and where Kissimmee falls on the strict-to-permissive spectrum compared to other cities.
ADU Rules
Kissimmee allows one accessory dwelling unit per lot in most residential zoning districts, but the principal home must be owner-occupied with a homestead exemption, and the ADU is capped at 800 square feet.
Key details: Max ADUs per lot: 1 (attached or detached). Living area: 500-800 sq ft. Occupancy rule: Owner-occupied + homestead. Detached ADU lot size: 1.5x district minimum.
An ADU built without following these standards is illegal; the code requires it be brought into compliance with the section or abated: there is no grandfathering for unauthorized units.
Shed & Carport Rules
Sheds and other accessory structures in Kissimmee must sit at least six feet from the rear property line, meet side-yard setbacks, and stay under half the size of the main house under the Land Development Code.
Key details: Governing section: LDC § 14-6-1. Rear setback minimum: 6 feet from property line. Size limit vs. main house: Under 50% of square footage. Taller sheds (12ft+): Must meet full building setback.
A shed built inside the required rear or side setback, or one that exceeds 50 percent of the house's square footage, is a code violation the building division can order relocated, resized, or removed.
ADU Owner Occupancy
Kissimmee only allows an accessory dwelling unit where the main house is owner-occupied and holds a valid homestead exemption, so an owner who doesn't live on the property can't add a legal ADU.
Key details: Governing section: LDC § 14-6-2.C. Requirement: Owner-occupied with homestead exemption. Effect: Bars investor-only rental ADUs. Non-compliant ADUs: Subject to abatement.
An ADU built or occupied on a property where the owner doesn't live and hold homestead status is illegal under § 14-6-2.C and, per the same section, must be brought into compliance or abated.
Compared to other cities, Kissimmee takes a harder line on adu owner occupancy. The enforcement and penalty structure reflects that.
The Bottom Line
Kissimmee's accessory structures rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Kissimmee is broadly strict or permissive.
All of the above reflects Kissimmee's municipal code as of our last review. If you need specifics on fines, exemptions, or filing requirements, the detailed ordinance pages linked above have the full breakdown.
