19.28.010 Purpose.¶
The purpose of this chapter is to establish the land uses that may be allowed within the duplex and multifamily residential zones established by Chapter 19.12 (Zones Established—Boundaries and Zoning Map), determine the type of zoning permit (if any) required for each use, and provide objective design development standards for design, site layout, and building size. These requirements constitute “objective standards” under current State housing law, including but not limited to Government Code Sections 65913.4, 655589.5, and 756852.21* , to provide clear development standards that allow for nondiscretionary, streamlined review processes.
The duplex and multifamily zones are intended to promote and encourage the establishment and maintenance of a suitable environment for family living in areas appropriate by location and character for single-family, two-family, and multifamily dwellings. (Ord. 2025-10 § 8, 2025.)
*** Code reviser’s note:** Per the City of Belvedere, the correct Government Code Sections are 655832(h) and (i).

A. Incentives for Affordable Housing and Lot Consolidation in the R-3 Zone. The following standards shall apply to a development project in the R-3 zone that (1) consolidates parcels so that the development site acreage is one-half acre or greater and (2) creates three or more new units, with twenty percent of the new units affordable to households making less than eighty percent of the area median income:
Lot Area/Unit. The maximum allowable density (i.e., minimum lot area/unit) shall be calculated over the total combined area of contiguous parcels equal to or greater than one-half acre under common ownership.
Density. The minimum allowable density on the consolidated site shall be twenty units per net acre and the maximum allowable density shall be twenty-eight units per net acre.
Off-Street Parking. Only one parking space and one-half common parking space is required per unit.
Usable open space: one hundred fifty square feet of private open space and one hundred fifty square feet of public open space if the development site is within one thousand linear feet of an existing park.
Maximum lot coverage: forty-five percent.

If this is determined to be technically infeasible by a licensed engineer, ground-level utility boxes and equipment may be located in the front setback but shall be screened from all direct sight lines from public sidewalks by a physical enclosure and/or shrubs that can be expected to grow to the same height as the box or equipment.
D. Exterior Finish Materials. Allowable exterior building materials are set forth below. Materials not allowed include vinyl and aluminum products, including those intended to simulate wood, and rough sawn wood. Concrete block is not allowed, unless concealed by allowable materials listed below.

E. Windows.
Window Type. Operable windows shall be limited to double-hung, awning, sliding, or casement type windows.
Operable Windows. Rooms with exterior windows shall include one or more operable windows, except where exclusive use of fixed windows is needed to mitigate excessive noise or air quality impacts.

Roof-mounted mechanical equipment shall be entirely recessed within a sloped roof, or surrounded on all sides by a parapet wall with a top edge as high as the topmost point of the equipment. The following are exempt from the limitations of this subsection: solar panels and equipment required by fire departments and other public agencies. (Ord. 2025-10 § 8, 2025.)
19.28.060 Landscape design.¶
A. Landscaped Setbacks. Setback areas shall be planted areas, except for areas necessary for pedestrian access, parking and vehicular access, and where utilities preclude landscaping.
