ADU Construction in La Palma

Affordable entry into a well-maintained OC community with strong neighborhood character, low crime rates and family-friendly atmosphere driving steady rental demand, proximity to major freeways and employment centers, and a straightforward city permitting process suited to the small-city scale.

La Palma is one of Orange County's smallest and most tightly knit communities — just 1.8 square miles with approximately 15,000 residents. Despite its compact size, the city maintains an exceptional quality of life with well-kept neighborhoods, Central Park as the community's green heart, the La Palma Community Center, and a strong volunteer-driven civic culture. The residential character is predominantly single-family homes built in the 1960s and 1970s on lots typically ranging from 5,000 to 7,000 sqft. La Palma's location in northwest Orange County provides convenient access to the 5 and 91 freeways, placing residents within a short commute of Anaheim, Buena Park, and Cerritos employment centers. The city's quiet streets, low crime rates, and community-oriented atmosphere make it a hidden gem for families seeking an affordable OC foothold.

Zoning & requirements

Setbacks
4-foot minimum from rear and side property lines for new detached ADUs. Conversions of existing structures are exempt from setback requirements.
Height
Up to 16 feet for single-story detached ADUs. Up to 25 feet for two-story ADUs per state law (AB 1332) in qualifying residential zones.
Parking
One parking space per ADU may be required. Exempt if within 0.5 miles of public transit, within one block of a car-share vehicle, or if the ADU is a conversion of existing space.
Lot Size
5,000–7,000 sqft typical residential lots. La Palma's uniform grid layout means most lots have consistent dimensions and predictable buildable areas. No minimum lot size required by state law to build an ADU.
Owner Occupancy
No owner-occupancy requirement for ADUs (made permanent by AB 976 in 2025).
Additional Notes
La Palma's compact lot sizes favor efficient ADU designs — garage conversions and smaller detached units (500–750 sqft) are popular choices. ADUs under 750 sqft are exempt from impact fees, making this size range particularly cost-effective in La Palma.

How to permit your ADU in La Palma

01

Verify lot & zoning

Confirm your property's zoning designation and lot dimensions with the Community Development Department. La Palma's consistent residential grid makes most properties straightforward to evaluate. Check for any easements or utility restrictions.

02

Design your ADU

Create architectural plans including site plan, floor plan, elevations, structural, mechanical, electrical, and plumbing. La Palma's 5,000–7,000 sqft lots work well for compact detached ADUs (500–750 sqft) or garage conversions. Include Title 24 energy compliance documentation.

03

Submit to Community Development

Submit your complete plan set to the Community Development Department. La Palma's smaller staff means you often work directly with senior planners — take advantage of this accessibility to address questions early in the process.

04

Plan check review

The city reviews plans for compliance with building codes and ADU regulations. State law mandates a 60-day maximum review period for compliant ADU applications.

05

Build & inspect

Once permitted, begin construction with your licensed contractor. Schedule required inspections at each milestone — foundation, framing, rough MEP, insulation, and final.

06

Final inspection & occupancy

Request final inspection from the Building Division. Once passed, receive your Certificate of Occupancy. Your ADU is now legal to rent or occupy in La Palma's consistently strong rental market.
