You are allowed to put one attached or detached ADU on single-family property in Temple City, as well as one JADU.

Multifamily property owners in Temple City may convert existing uninhabitable space into at least one attached ADU, and additional ADUs not to exceed a maximum number equal to 25% of the existing units. Ergo:

  • From 8 to 11 units up to 2 ADUs
  • From 12 to 15 units up to 3 ADUs

ADU Temple City – Size & Building Constraints

A detached studio ADU can be up to 600 square feet, while a detached one-bedroom ADU can be up to 850 square feet, and a detached two-bedroom ADU can be up to 1,000 square feet.

An attached ADU in Temple City can be up to 800 square feet, or 50% of the square footage of the primary dwelling unit, whichever is smaller.

An ADU in Temple City can usually be built to a maximum height of 16 feet.

The maximum height requirement of 16 feet effectively prohibits you from building a two-story ADU in Temple City.

Two-story ADUs are not allowed in Temple City, so you cannot have two ADUs stacked one on top of another with one on each story of a two-story structure.

Since only one ADU is allowed on single-family property in Temple City, you cannot have two ADUs attached to one another in one structure. Detached structures containing multiple ADUs may be permitted on multifamily property.

No, a JADU is defined as an ADU converted from existing space within the main structure of the primary dwelling unit. As such, it cannot be attached to an ADU.

Generally roof decks would be permitted on an ADU, but must meet the height restrictions for the zone. Roof decks cannot encroach into the required setbacks. As a rule of thumb, railings and access staircases above 42″ need to be included in height calculations.

An ADU must match or harmonize with the exterior of the main dwelling unit, including color palette, roof pitch, architectural style, and other aesthetic characteristics.

Temple City may require a soils report for ADU permitting to make sure the soil can support the new structure, especially if the ADU will be located on a hillside, an area with significant grading, or if there are special foundation requirements.

Sufficient green space and permeable surface must be maintained on the property. City regulations do not specify specific percentages and must be approved on a case-by-case basis in the planning stage.

Plans are submitted to the Temple City Building and Safety Division, which checks the plans for compliance with building codes, safety codes, and structural integrity. Turnaround times can vary, but the process takes an average of two weeks.

Parking for Temple City ADU

One new parking spot is typically required to be added to the lot per new ADU. However, exemptions may apply if:

 

  • The ADU was built into an existing structure.
  • The property is located within a historic district.
  • The property is located within ½ mile walking distance of a public transportation stop.
  • The property is located within one block of an established vehicle share stop.
  • Off-street parking permits are required but not offered to ADU occupants.

If a parking space must be added, it can be included on the driveway or any setback areas, and it may be configured as tandem parking.
