Full Breakdown
370, part of the Title 24 Improvements chapter that the county Public Works Department (defined in this title as 'the agency') administers for development in the unincorporated area, sets a schedule of required off-street loading spaces tied to a building's gross floor area and use category. For hotels, motels, offices, banks, hospitals and convalescent homes (Category A), no loading space is required up to 10,000 square feet, one small space is required between 10,000 and 50,000 square feet, one small plus one large space between 50,000 and 100,000 square feet, and one additional large space for each additional 100,000 square feet or fraction thereof.
Retail and personal service stores, and industrial, wholesale and storage uses (Category B), start at one small space for buildings between 3,000 and 10,000 square feet, one small plus one large space up to 100,000 square feet, and one additional large space per additional 100,000 square feet. The code fixes dimensions for compliance: a small loading space must measure twelve feet by twenty-five feet, and a large space twelve feet by forty-five feet, so a project cannot satisfy the requirement with an undersized bay. 04, adopted by Ordinance No.
340-B. Developers proposing hotels, retail centers, offices or warehouses in unincorporated communities such as Strawberry, Tamalpais Valley or Kentfield must show the required loading bays on improvement plans submitted to the Public Works Department before permits are approved.
Violations & Fines
Improvement plans that omit the required loading bays, or undersize them below the twelve-by-twenty-five-foot small space or twelve-by-forty-five-foot large space standard, do not conform to Chapter 24.04 and can be rejected or conditioned by the Public Works Department during plan review. Because loading spaces are a development standard rather than a parking violation, enforcement runs through the permit and improvement-plan approval process rather than citations issued after construction.
