Definitions for "Granny flat"
A freestanding, single-unit (usually single-story) apartment building located behind the main house in a residential area. It is permitted in areas with adopted neighborhood plans that specifically allow them. It is also conditionally permitted in zoning districts SF-3 and SF-5 if the lot is larger than 7,000 square feet. In areas that do not meet these criteria, a variance is required for construction.
See the In-Law Unit entry.
Slang term for a separate unit in a house or above the garage, which in the past may have been occupied by an elderly relative.
