5 rules for unincorporated Lake County, Florida.
Verified from official government sources
Unincorporated Lake County allows one accessory dwelling unit (ADU) per lot in agricultural and residential districts. The ADU may be an apartment or stand-alone building, must be owner-occupied (owner in either unit), and is capped at 1,200 sq ft or 70% of the main home, whichever is greater.
Lake County LDR Sec. 10.01.03
No more than one (1) Principal Dwelling Unit and one (1) Accessory Dwelling Unit Shall be permitted on any Lot of Record. The enclosed living area of the Accessory Dwelling Unit Shall not exceed one thousand two hundred (1,200) square feet or seventy percent (70%) of the air conditioned, enclosed living area of the principal dwelling, whichever is greater.
In unincorporated Lake County, a shed must sit on a lot with a lawful home, stay out of required setbacks and buffers, and (on lots under an acre) not exceed 80% of the home's living area. It cannot be taller than the house or 25 feet.
Lake County LDR Sec. 10.01.01
For lots less than one (1) acre in size, the square footage of an Accessory Structure(s) shall not exceed eighty (80) percent of the main floor square footage of the enclosed living area of the dwelling unit. Cargo and shipping containers shall not be used as Accessory Structure(s) in residential zoning districts.
Lake County's LDR has no stand-alone 'garage conversion' rule. Converting a garage into separate living quarters is treated as creating an Accessory Dwelling Unit — one per lot, owner-occupied, size-capped, and permitted under the Florida Building Code. A conversion into more of the main home simply needs a building permit.
Lake County LDR Sec. 10.01.03(B)(4)
The structure shall be determined to be an Accessory Dwelling Unit: a. A separate utility meter may service the additional living space; b. The additional living space may have a separate address; c. it may be connected to the primary dwelling by a breezeway or walkway; or d. it qualifies as a separate dwelling under the Florida Building Code.
A carport is a residential accessory structure in unincorporated Lake County. It must stay out of required setbacks and buffers and generally go in a side or rear yard unless it matches the home's style. It cannot exceed the house height or 25 feet.
Lake County LDR Sec. 10.01.01
Accessory structures that are buildings shall be located in side and rear yards, unless the accessory building is the same architectural style and the exterior walls and roof are the same material and color as the principal dwelling unit. An Accessory Structure(s) shall not be located in a required Buffer area, Landscape Buffer, wetland buffers or minimum Building Setback area.
Lake County has no dedicated 'tiny home' category. A permanent tiny house is treated as a small single-family dwelling meeting zoning and the Florida Building Code. Living in an RV or trailer is allowed only as temporary construction housing, on 1+ acre lots, with a permit and $5,000 bond.
Lake County LDR Sec. 10.02.02
A single-wide mobile home, travel trailer, or recreational vehicle may be occupied as a temporary residence in agricultural or residential zoning districts for one (1) family on a lot of record or legally created lot that is one (1) acre in area or greater while a permanent residence is being constructed thereon.
