ADU rules in Winter Park

3 sources

These are the primary sources for accessory dwelling unit regulations in Winter Park: the city's own zoning code, planning department pages, and permit guides. Start here before talking to anyone: the rules below are what your permit reviewer will apply.

Rules at a glance

Detached (backyard) ADU

Conditional

True detached ADUs (garage apartments or accessory cottages that can be rented and separately metered) are allowed only on designated historic landmarks or resources, or on properties in a designated historic district, and only if the Historic Preservation Board determines them to be conforming uses; historic designation must be completed before a building permit is issued. On ordinary lots, detached guesthouses or garage apartments up to 1,000 sq ft are permitted accessory uses but may not have a kitchen or cooking facilities, separate utility meters, or be rented, so they are not true dwelling units.

Code of Ordinances Sec. 58-469(3); Sec. 58-71(10)

Attached or internal ADU

Not allowed

The code's only ADU pathway, Sec. 58-469(3), covers garage apartments and accessory cottages, which are accessory buildings; conversion of existing garage space is expressly prohibited (an existing garage may only be enlarged to accommodate the apartment). Neither Sec. 58-469 nor the general zoning provisions in Sec. 58-71 authorize an attached or interior accessory dwelling within the principal residence.

Code of Ordinances Sec. 58-469(3)(d); Sec. 58-71(10)

Maximum size

Historic-property ADUs: the code states it is desirable that garage apartments or accessory cottages not exceed 750 sq ft of living area; the Historic Preservation Board may reduce or enlarge that limit based on property size or configuration, but never above a hard cap of 1,000 sq ft. Ordinary (non-rentable, kitchenless) guesthouses or garage apartments: 1,000 sq ft of floor area maximum.

The 750 sq ft figure is a stated target, not a fixed limit; only the 1,000 sq ft cap is absolute.

Code of Ordinances Sec. 58-469(3)(c); Sec. 58-71(10)

Owner occupancy

Not required

Neither Sec. 58-469(3) (historic-property ADUs, which expressly contemplate tenants) nor Sec. 58-71(10) contains an owner-occupancy requirement. Sec. 58-71(10) does tie ordinary guesthouse occupancy to guests, domestic service employees, or members of the family occupying the main building, which is an occupancy restriction but not an owner-occupancy mandate.

Code of Ordinances Sec. 58-469(3)(e); Sec. 58-71(10)

Extra parking

Yes, for historic-property ADUs: tenants must be provided on-site parking space(s) behind the front setback of the principal residence; every required space must be independently accessible without moving another vehicle, and all vehicles must park on site so no regular daytime or overnight parking occurs on city streets. Generally, residential projects of two units or less require two off-street spaces per dwelling unit.

Separate electric meters and utility connections are contingent on meeting the ADU parking requirements; violation of the historic-ADU parking terms can trigger code compliance enforcement (Sec. 58-469(3)(e)).

Code of Ordinances Sec. 58-469(3)(d)-(e); Sec. 58-86(b)(20)

Approval process

Conditional use

Not a standard conditional use permit: a rentable ADU requires Historic Preservation Board approval through the historic preservation certificate of review process, and is available only after the property completes individual landmark, resource, or historic district designation. The HPB determines the garage apartment or accessory cottage to be a conforming use and sets its setbacks. Ordinary non-rentable guesthouses are permitted accessory uses under Sec. 58-71(10).

Code of Ordinances Sec. 58-469(3), (3)(a)-(b)

Rental restrictions

Rental is allowed only for HPB-approved garage apartments or accessory cottages on historic-designated properties; Sec. 58-469(3)(e) expressly contemplates tenants, subject to the on-site parking conditions. Everywhere else, guesthouses and garage apartments may not be rented, let, or hired out for occupancy, whether compensation is paid directly or indirectly, and may not have kitchens or separate utility meters.

The code sections read this session do not state a minimum lease term for historic-property ADU tenants.

Code of Ordinances Sec. 58-469(3)(d)-(e); Sec. 58-71(10); Sec. 58-95

The fine print: 5 caveats that can change the picture

Ordinary residential lots cannot have a true ADU: guesthouses and garage apartments outside the historic program are limited to 1,000 sq ft and may not have kitchens or cooking facilities, separate utility meters, or be rented (Sec. 58-71(10)), and may only house guests, domestic service employees, or members of the family occupying the main building.
The rentable-ADU pathway requires completed historic designation (individual landmark, resource, or location in a designated historic district) before any building permit or approval is issued (Sec. 58-469(3)(a)).
Conversion of existing garage space into the apartment is prohibited; an existing garage may only be enlarged in height or ground area to accommodate a garage apartment (Sec. 58-469(3)(d)).
A guesthouse or garage apartment may not be built for occupancy before the main building is completed (Sec. 58-71(9)).
HPB sets building setbacks case by case, but no garage apartment or accessory cottage may be closer than five feet to a rear or side lot line unless such a setback already exists, and none may be in a required front setback (Sec. 58-469(3)(b)).

Summarized from Winter Park's ordinance text, read July 2026; every row links the code section it came from. Rules often vary by zone and lot, so treat this as orientation, not a permit determination, and confirm with the planning department before you commit to a design.

ADU regulations

Florida statewide law also applies

Florida sets baseline ADU rights at the state level. Where local rules are stricter than state law allows, state law usually wins, so both are worth reading.
