Who We Are
Our company focuses on residential architectural plans and permitting exclusively on ADUs, garage conversions, additions, and legalization of unpermitted work. This focused approach allows us to move faster, produce clearer drawings, and anticipate what each city will require during review.
Our team includes architectural designers, engineering strategists, energy specialists, and permit coordinators who work together under one roof. You do not have to coordinate multiple vendors or wonder who is responsible at each step.
Our role is to deliver complete, code ready plans and guide your project through city approval with as few delays as possible.
What Makes CPA Different
A Single Team for Plans and Permits
Architectural drawings, engineering coordination, Title 24 energy reports, green code documents, and full permit management are all handled by us. This keeps your project organized and moving.
Type V Prescriptive Engineering
Our approach helps avoid unnecessary structural engineering whenever possible. This saves time and often saves thousands of dollars for clients.
Fast and Predictable
We understand how Southern California cities think. Our plans are prepared to minimize corrections and keep your project progressing.
Unlimited Corrections
If the city asks for changes within your approved concept, we handle every correction without charging additional fees.
Trusted by Contractors and Architects
Many contractors rely on us as their plans and permitting department. Architectural firms partner with us to manage submittals and corrections so they can focus on design.
Clear and Transparent
Clients appreciate that we explain everything in simple terms, never hide fees, and keep communication open at every step.
