How Kissimmee Handles Accessory Structures: A Practical Guide

Kissimmee maintains 83 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

LDC §14-6-2 allows one ADU per lot (attached or detached) if the lot meets minimum zoning-district lot size. Detached ADUs require 1.5x the minimum lot size. Living area: 500-800 sq ft or 40% of the primary structure, whichever is less. The principal structure must be owner-occupied with a valid homestead exemption.

Key details: Code Section: LDC §14-6-2. Max Per Lot: 1 ADU. Detached Lot Size: 1.5x district min. Min Living Area: 500 sq ft. Max Living Area: 800 sq ft or 40% of primary.

Zoning violation: Sec. 1-22(b)(12) — $250. Illegal ADU operation triggers code-board fines up to $250/day first violation, $500/day repeat. Failure of homestead requirement can trigger abatement.

Shed Rules

Sheds are accessory structures governed by LDC §14-6-1. Florida Building Code exempts one-story detached accessory structures under 200 sq ft from the building permit requirement, but Kissimmee zoning rules on setback (typically 5 ft side/rear) and lot coverage still apply.

Key details: Code Section: LDC §14-6-1. FBC Permit Exempt: Under 200 sq ft. Zoning Review: Always required. Side/Rear Setback: 5 ft typical. Habitable Use: Prohibited (becomes ADU).

Construction without zoning review: Sec. 1-22(b)(12) — $250. Construction without building permit (over 200 sq ft): Sec. 1-22(b)(2) — $100. Habitable use of a shed violates §14-6-2 ADU standards.

Garage Conversions

Converting a garage into livable space requires building permit review and likely triggers ADU rules under LDC §14-6-2. Off-street parking requirements under §14-7-22 must still be met after conversion — typically requiring a replacement driveway parking space.

Key details: Code Section: Sec. 9-115, LDC §14-6-2. Permit Required: Yes (all elements). Parking Replacement: Required. ADU Classification: If separate kitchen + entry. Max ADU Size: 800 sq ft / 40% of primary.

Sec. 1-22(b)(2) — $100 construction without permit. Sec. 1-22(b)(12) — $250 zoning violation. Habitability violations: Code Enforcement Board $250/$500 day. Building Official can issue order to abate (remove conversion) or bring into compliance.

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.
