Construction of dwellings or any remodeling or additions to existing dwellings shall have a floor area ratio (FAR) which limits the maximum building area to 55 percent of the lot. The floor area ratio calculation shall also include the square footage of patios, garages and other accessory structures present on the lot. For these purposes, an “accessory structure” is defined as any structure which rises four or more feet above finished grade. (Ord. 3153 § 2 (Exh. A), 2010; Ord. 2559 § 5, 1993; Ord. 2144 § 4, 1986).
