ADU Plans in Long Beach
Long Beach is the second-largest city in LA County with its own comprehensive building code, zoning ordinance, and plan check process. It functions almost as independently as the City of LA, and designers who treat it like a smaller suburb get their plans rejected. We’ve completed projects throughout Long Beach – from Belmont Heights to Bixby Knolls to the East Side – and understand the city’s specific requirements.
Why Long Beach Clients Work With Us
Long Beach has been particularly proactive about ADU development, and their building department has streamlined the process for well-prepared applications. We deliver construction document packages that address Long Beach’s specific checklist items, local amendments, and energy compliance requirements.
With 1,500+ projects completed across Los Angeles County since 2015, we bring a depth of experience that most firms can’t match. We don’t just know the California building code – we know how Long Beach’s building department applies it.
Long Beach operates its own comprehensive building code and plan check process – independent from LA County – with specific local amendments and procedures.
