Introducing Our Latest ADU Project in Los Angeles
Apr 15
Legalizing an unpermitted ADU in California doesn’t have to be complicated.
In most cases, the process involves reviewing the existing unit, preparing as-built drawings, identifying code issues, submitting permit plans, and completing any required corrections.
California AB 2533 may help homeowners legalize certain unpermitted ADUs and JADUs built before January 1, 2020, while focusing primarily on correcting health and safety issues. It also limits permit denials and encourages homeowners to come forward without penalties.
Process typically includes:
✨ Reviewing the existing ADU or the existing structure
✨ Preparing as-built drawings
✨ Identifying code issues
✨ Creating permit plans
✨ Submitting to the city for approval

Sharing our success story for a 1,199 SF custom detached ADU in Santa Clara.
This project was designed for high-value, flexible living and involved some real design challenges: lot constraints, setback requirements, and a rear property easement.
The Goal
Create a spacious second unit for rental income or long-term family use, while preserving the privacy and character of the existing home.
The Challenge
Maximize buildable area, maintain independent living, navigate a rear easement, and meet all required clearances from property lines.
How We Solved It
We strategically placed the ADU to work around easement and setback constraints, relocated fencing to maintain required clearances, and reconfigured the patio for better privacy and curb appeal, all while staying fully aligned with zoning requirements for a smooth permitting path.
The Result
A fully independent, permit-ready living space with 1,199 sq. ft. of optimized design, featuring:
✅ Soaring 16-ft vaulted ceilings in the living area
✅ A dedicated laundry and utility room
✅ A front porch that enhances curb appeal
The final design improved privacy between the two homes while positioning the property for long-term added value.
This is where great ADU projects begin: smart design, careful code navigation, and a team that knows how to turn constraints into opportunities.
