ADU rules in Kissimmee

One ADU, attached or detached, may be developed per lot, provided the lot complies with the minimum lot size for the zoning district. A detached ADU requires a lot with 1.5 times the minimum required lot size. The Chapter 14-2 definition covers an attached or detached extension to an existing or proposed single family structure.

One ADU (attached or detached) per lot; an attached ADU needs only the district minimum lot size, not the 1.5x lot required for detached units. Permitted by right (P) in the AC, RE, RA-1 through RA-4, RB-1 and RB-2 districts per Table 4-1 (AC is P/C: new ADUs there are conditional).

An ADU shall have a minimum living area of 500 square feet and a maximum living area of 800 square feet or 40 percent of the gross floor area of the principal structure/dwelling at time of application, whichever is less. The 500 sq ft floor is unusual: units smaller than 500 sq ft of living area do not qualify.

The principal structure shall be owner-occupied and shall maintain a valid homestead exemption. Kissimmee enforces owner occupancy through the Florida homestead exemption, which is only available on an owner's permanent residence.

Sec. 14-6-2.B requires off-street parking per Sec. 14-7-22 in addition to the parking required for the primary structure. Table 7-2 sets the ADU ratio at 1 space per unit; single family dwellings require 2 spaces per unit.

Table 4-1 lists accessory dwelling units as a permitted use (P) in the RE, RA-1, RA-2, RA-3, RA-4, RB-1 and RB-2 residential districts, subject to the Sec. 14-6-2 standards; the AC district is P/C (existing pre-annexation units deemed permitted, new units require conditional use approval). Also permitted in the RPB nonresidential district (Table 4-2) and in the T3, T4-R and T4-O downtown transect zones (Table 5-1).

Sec. 14-6-2 is silent on renting the ADU: no short-term rental limit, lease minimum or tenant restriction appears in the section, and a full-code search for accessory dwelling language found no ADU-specific rental rules. The owner occupancy and homestead exemption requirement for the principal structure is the only occupancy control.
