ADU Plans in Alhambra
Alhambra is one of the most active cities in the San Gabriel Valley for residential development and ADU construction. We’ve completed a significant number of projects in Alhambra — from detached ADUs to full home remodels — and have a deep understanding of the city’s building department, plan check process, and local code requirements.
Why Alhambra Clients Work With Us
Alhambra’s residential lots range from compact urban parcels to larger properties with substantial ADU potential. We evaluate each site during our initial consultation and design solutions that maximize value while meeting all applicable codes and setback requirements.
With over 1,500 residential and commercial projects completed across Los Angeles County in the last decade, we bring a depth of experience that most firms can’t match. We don’t just know the California building code — we know how Alhambra’s building department applies it.
Alhambra’s building department processes a high volume of ADU applications and expects thorough, well-organized submittals.
