Pre-approved plans
County pre-approved designs, designed and built by one coordinated team.
LA County maintains a catalog of pre-approved home designs that have already cleared zoning and code review — homeowners who choose one generally need only site-specific review. ROAM Design Studio LLC is preparing a family of Altadena designs for submission to the county's pre-approval program, and ROAM Builders Inc. can build them under a separate construction agreement. Two companies. One coordinated team.
How the county program works
- Designs in the county catalog are reviewed once, up front, against zoning, building codes, and the Altadena Community Standards District.
- When you choose a catalog plan for your lot, the county reviews only the site-specific items — placement, utilities, site conditions — rather than the full design.
- Pre-approved plans cannot be customized; changes move a project back into the general review process. The right fit matters more than with a custom design.
What ROAM is bringing to the catalog
Designs that fit Altadena's character — drawn with Chapter 7A fire-hardening built in, sized against realistic insurance-proceeds budgets, engineered by licensed engineers, and reviewed for buildability by the team that will build them. Each design we submit will be published here with its county status clearly marked; nothing on this page will be called "pre-approved" until the county's approval actually exists.
