South Pasadena, California Zoning Map

The DTSP covers 122 acres along the city's main commercial corridors and is the primary entitlement vehicle for mixed-use, multifamily, and commercial development in South Pasadena. Specific plan districts typically carry their own development standards - density, height, parking, and design guidelines - that differ from the base zoning. The downtown's Metro Gold Line station makes transit-oriented development possible, and the plan generally supports ground-floor retail with residential above.

AM (Altos De Monterey) at 276 acres covers a hillside residential neighborhood with its own set of development standards tailored to sloped terrain, larger lots, and the character of that specific area. It effectively functions as an estate-to-low-density hillside zone. Projects in AM should account for potential grading restrictions, slope stability requirements, and the neighborhood's design review expectations, which may differ from standard RS regulations.

Residential High Density (RH, 170 acres) and Residential Medium Density (RM, 218 acres) together offer about 388 acres of multifamily-eligible zoning - a meaningful portion of the city given its small overall footprint. These districts are distributed throughout the city and are the most viable locations for apartment or condominium development. State ADU law and density bonus programs apply citywide and can incrementally expand capacity on qualifying parcels.

South Pasadena has one of the more active historic preservation programs among small San Gabriel Valley cities. The city maintains a list of historic landmarks and is home to neighborhoods with potential historic district status. Alterations, demolitions, or new construction near designated structures may require a Certificate of Appropriateness or trigger CEQA historic resource analysis. Investors acquiring older buildings should budget for a historic resource assessment early in due diligence.

Industrial and heavy commercial uses are almost entirely absent from South Pasadena's zoning map. The Business Park (BP) zone at just 18 acres is the closest the city comes to an employment-industrial district, and it is oriented toward low-impact office and light industrial rather than manufacturing or logistics. Anyone considering an industrial or major commercial program should expect limited site availability and a community that prioritizes residential character over employment intensification.
