A. In LR and MR zones, the minimum required separation between structures containing floor area is 5 feet except that, if the structures are separated by a driveway or parking aisle, the minimum required separation between structures containing floor area is 2 feet greater than the required width of the driveway or parking aisle or 24 feet, whichever is less. If the structures are separated by a driveway or parking aisle, projections that enclose floor area may extend a maximum of 3 feet into the required separation if they are at least 8 feet above finished grade. B. Architectural features such as cornices, eaves, gutters, roofs, fireplaces, chimneys, and other forms of weather protection may project into required separations a maximum of 2 feet. Unenclosed structures allowed in side setbacks are allowed in the minimum separation. Garden windows, bay windows, covered porches and patios, balconies, and enclosed structures are not allowed in the required separation. Detached structures that are up to 10 feet in height and used exclusively for bike parking are allowed in required separations. (Ord. 127376 , § 39, 2025.)
