ADU rules in Clermont, FL — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
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.
Under LDR Sec. 10.01.03, an ADU is a self-contained dwelling with its own entrance, kitchen and bath sharing the lot with a single-family home. No more than one principal dwelling plus one ADU is allowed per lot of record. Before a permit issues, the owner must record a covenant keeping both units in common ownership and limiting occupancy to the owner. The enclosed living area may not exceed 1,200 sq ft or 70% of the principal home's air-conditioned area, whichever is greater. On lots under one acre the ADU must match the main home's architectural style. The two units must share a common driveway, and impact fees apply. Inside cities like Clermont or Leesburg, city rules govern.
Building a non-compliant ADU or renting it in violation of the recorded owner-occupancy covenant is an LDR violation enforced through Chapter 8 (Code Enforcement Special Master); general penalties reach $500 or 60 days jail per Sec. 1-6.
