Zoning
R-1 LL
Single-Family Large Lot District
The purpose of the single-family residential large lot or R-1LL district is to provide for detached single-family residential development of the hillside lands in Millbrae for relatively low densities commensurate with the natural topography, tree cover, and surface drainage patterns which typify those areas. This district correlates with the very low density residential land use designation of the Millbrae General Plan.
