Detached backyard cottages, attached units and garage-conversion ADUs — your lot’s zoning checked first, then designed, permitted and built by one licensed team.
We typically reply the same business day.
Right Image Inc (Right Image Builders) is a licensed and insured Florida general contractor (CGC1539321) based in Oviedo, building accessory dwelling units (ADUs) across Orlando, Seminole and Orange County — detached cottages, attached units and garage conversions. We check what your city or county allows on your lot before design starts, then handle engineering, permits and construction under one contract.
ADU Construction in Greater Orlando, FL — planning ranges (updated October 2026): ADU / garage conversion $50,000 – $180,000. Permits run through your city or county building department. Ranges are planning figures, not a quote — every project is priced after a site visit.
Accessory dwelling units are decided by zoning before they are decided by design. Each city and county around Orlando sets its own rules — where an ADU may go, how big it can be, whether the owner must live on the property, whether it may be rented and how much parking it needs. The section below summarises each jurisdiction with the code section we read.
We check the rules for your parcel, confirm setbacks with a survey, and only then design: a detached cottage, an attached unit with its own entrance, or a garage conversion. Then we handle the engineering, permits, utility connections and construction under one contract.
A separate cottage with its own kitchen, bath and entrance — foundation, framing or block, roof and utilities built to the Florida Building Code and your local ADU rules.
A unit built onto the house with its own entrance, kitchen and bath, where your jurisdiction allows an attached accessory unit.
An attached or detached garage turned into a self-contained unit: leveled floor, insulation, door infill, windows, kitchen and bath.
Lot and zoning check, survey, plans, structural engineering, energy calculations and permits — plus HOA or architectural review where it applies.
What each city and county allows, summarised from the code section we read. Rules change — we confirm them for your parcel before design.
Oviedo allows one accessory dwelling unit per lot, attached or detached, in its single-family, agricultural and downtown-neighborhood districts with a zoning permit and a building permit — no public hearing. The ADU must have its own entrance, kitchen and full bathroom, match the main house, sit no closer to the street than the house, and can't be sold separately.
Permit authority: City of Oviedo Building Services
Winter Springs allows an attached or detached ADU only through a conditional-use approval: a community workshop, a Planning & Zoning Board recommendation and a City Commission decision, with notice to neighbors within 150 feet. The owner must live in the main house or the ADU, it may be leased only for residential use and can't be sold separately, and HOA covenants that prohibit ADUs block approval.
Permit authority: City of Winter Springs Building Division
Unincorporated Seminole County — including Chuluota, Geneva and Black Hammock addresses outside city limits — allows one ADU per single-family lot: by right in A-3, A-5 and A-10, and with the Planning Manager's administrative approval in the R-1 districts, RC-1, A-1 and single-family PD lots, with no public hearing. The owner must live in one of the units, leases must run at least 30 days, and the ADU can't be sold separately.
Permit authority: Seminole County Building Division
Casselberry has not adopted an ADU ordinance. City staff conditions on recent accessory-structure approvals state that an accessory structure may not be used as a dwelling unit until the city adopts one, so a separate rentable unit isn't available today. An attached in-law suite without a full kitchen, permitted as a room addition, is the usual alternative.

Longwood's development code treats accessory dwelling units, including mother-in-law suites, as accessory structures that must meet the setbacks and site standards of their district. One ADU in 2024 went through a conditional use permit before the City Commission, so we confirm the approval path and the size limit with the city for your lot before design.

Lake Mary has no ADU use. A guest house or garage apartment is permitted only in the A-1 and R-CE districts, for family members of the main household or their non-paying guests — it can't be rented. It is sized as a share of the main house, keeps unity of title and needs one off-street space on the same driveway. The R-1 and R-2 districts allow only customary accessory uses.

Sanford allows one accessory dwelling unit inside the main house or one separate accessory residential structure on the lot. Either may be occupied only by the owner, a relative of the owner-occupant, or a caretaker employed on the premises. They're approved administratively in SR-1AA, SR-1A and SR-1 (with a published notice of approval) and by conditional use at a Planning and Zoning Commission hearing in other districts.

Altamonte Springs does not permit ADUs, granny flats or garage apartments by right anywhere in the city. A guest house without kitchen facilities is permitted in the R-1AAA, R-1AA and R-1A districts, one per home; a guest house with cooking facilities needs a conditional use approved by the Planning Board after a public hearing. The R-1 districts don't allow guest houses.

The City of Orlando allows one ADU per lot — attached, detached, above a garage or as a garage conversion — in all R and MXD districts and in O-1 and O-2, subject to minimum lot size. It is a permitted use, with appearance review alongside the building permit. Long-term rental is allowed and there is no owner-occupancy rule, but both units stay under one owner, and the ADU needs its own electric and water meters and a full kitchen.
Permit authority: City of Orlando Permitting Services
Unincorporated Orange County allows an attached or detached ADU only on homestead property: the main home and the ADU must stay under one owner, who must live in one of them, and the certificate of occupancy is held until the parcel qualifies as homestead. Long-term rental is allowed; rentals of 180 days or less are prohibited. The county's Ready Set Orange program offers free pre-reviewed ADU floor plans.

Winter Park doesn't allow a rentable ADU. Guesthouses and garage apartments of up to 1,000 sq ft are permitted only to house guests, domestic staff or family members of the main house, with no kitchen or cooking facilities, no separate utility meters and no rental of any kind, and they can't be occupied before the main house is finished.
Permit authority: City of Winter Park Building & Permitting Services
Maitland permits a 'cottage residence' by right in its RSF-1, RSF-2, RSF-3 and RSF-D single-family districts and several others, but outside RSF-D it may not be rented or used as a separate dwelling unit, except by people who provide services only to that property. It has no separate utility meter, a deed restriction is recorded first in RSF-1, -2 and -3, and the occupant needs one dedicated parking space.

Winter Garden made an ADU a permitted accessory use in 2026 (Ordinance 26-17) on a homesteaded lot with one single-family home, across its single-family districts, residential PUDs and the Historic Downtown overlay. One ADU per lot, the owner must live in the main house, and the ADU needs a full kitchen and bath. Standard residential leases are allowed; rentals under 30 days are not, and the ADU can't be sold separately.
Permit authority: City of Winter Garden Building Division
Kissimmee's land development code allows one accessory dwelling unit per lot that meets the district's minimum lot size. The ADU must be 500 to 800 sq ft and no more than 40% of the main house, the main house must be owner-occupied with a homestead exemption, and a detached ADU needs a lot 1.5 times the district minimum. Whether your district needs a conditional-use review, we confirm with the city first.

St. Cloud lists accessory dwelling units as a permitted use in its single-family districts (R-E, R-1, R-1A and R-1B) under LDC Sec. 3.14.30, and ADUs are a standard building-permit type with the city. The size, occupancy and parking standards sit in Sec. 3.14.30, which the city was revising in 2026 (Ordinance 2026-17), so we confirm the current standards for your lot before design.

Unincorporated Osceola County lists an 'accessory living unit / guest home' as a permitted accessory use in single-family districts such as RS-1 and E-2. Its size, rental and siting standards are in LDC Sec. 3.6.1.A, which we confirm for your lot. In Celebration, the community's design guidelines and architectural review also govern any new structure, so that review comes first.
