LA County eCheck for Faster Home Approvals

LA County is partnering with Archistar to launch the new eCheck AI Pilot, a cutting-edge tool that reviews building plans for compliance with zoning and building rules using artificial intelligence.

Visit to view a dashboard with the number of registered users, the number of submitted plans, and the number of plans submitted for each of the three review types – building code essentials, like-for-like rebuild, and non-like-for-like rebuild.

If your single-family home was impacted by the Eaton Fire or the Palisades Fire and is located in a single-family (R-1) residential zone in the unincorporated Altadena or Sunset Mesa communities, you are invited to join as an Early Adopter.

How to participate in LA County eCheck

  • Sign up for a free account at
  • Look up your property address
  • Upload your architectural drawings in PDF format
  • Indicate whether your rebuild project is “Like-for-Like” or “Non Like-for-Like”
  • Receive your report from eCheck.
  • During the pilot phase, results may take up to 10 business days but may be delivered faster.
  • Review the report. Revise your plans and re-upload, if needed.
  • Download the final report and include it in your County Disaster Recovery Permit – Rebuild Project application.
