Temple City, California Zoning Map

With R1 (Low Density Residential) covering 1,442 acres and California state ADU law mandating by-right ADU and junior ADU eligibility on all single-family lots, the most accessible housing production strategy in Temple City is ADU development on existing R1 parcels. SB-9 lot-splitting also applies to qualifying R1 lots, allowing a parcel to be divided into two and each half to support a duplex - potentially yielding up to four units on what was a single-family lot. Both tools require no discretionary approval when state law standards are met.

The CSP (Crossroads Specific Plan) covers about 56 acres and is the city's primary vehicle for higher-intensity mixed-use and commercial development along the Rosemead Boulevard and Las Tunas Drive corridors. The specific plan sets its own design, density, and use standards that may permit residential above commercial at higher densities than the base MU zones. Developers interested in mixed-use infill should obtain the CSP document and compare its standards to the adjacent MU-L and MU-M zones to identify the highest-and-best-use configuration for a given parcel.

Temple City's R2 (Medium Density Residential, 231 acres) and R3 (High Density Residential, 122 acres) districts are the primary locations for apartment and small multifamily development. The city's building controls include density limits, FAR, setbacks, and height standards that govern what can be built, but specific numerical thresholds are not available from zoning data alone. Developers should request the R2 and R3 development standards directly from the community development department for accurate unit-count underwriting.

The MU-L (Mixed Use Low, 19 acres) and MU-M (Mixed Use Medium, 23 acres) zones were established to comply with state housing element requirements and allow a combination of residential and commercial uses, with MU-M permitting higher residential intensity. These zones are typically located along commercial arterials where the city wants to encourage transit-adjacent housing. Ground-floor retail with upper-floor apartments is the intended format; the MU-M zone is particularly relevant for housing developers seeking above-corridor density.

Temple City has only a single Industrial (I) zone covering approximately 30 acres, reflecting the city's predominantly residential and commercial character. The limited industrial land means that light manufacturing, contractor yards, or warehouse uses are highly constrained by competition for available sites. Investors in industrial product should note that this scale of industrial zoning is unlikely to support large-format logistics or distribution facilities, but may be suitable for small-bay business park product or creative office conversions.
