What happened
Buena Park launched Plan PreCheck, a city-funded pilot built by CrossBeam. Applicants upload plans and usually receive a corrections list within an hour, citing state building codes and local rules and checking records such as seismic hazard maps. It is free, voluntary, needs no account and allows three re-checks. Plan check now averages three rounds; the city's goal is one. Applicants resolving over half the flagged items get a FastPass for priority review. Reports are advisory; staff review every plan and the Building Official decides. Plans are not stored after pre-check.
Why it matters
A concrete applicant-facing design, with an advisory label, an incentive for using it, and no data retention, that cities can compare with staff-side permitting AI already in the archive.
Evidence and measured results
City press release with stated baseline (three rounds) and target (one); no results yet. Classed as vendor-claim because results and capabilities are asserted by the city and its vendor.
Limitations and uncertainty
No accuracy, usage or cost data; one-round goal is a target.

- Process for FastPass verification
- Vendor terms on data handling
- Constraints
- California code amendments
- Vendor-specific accuracy
- No retention limits audit stated
- Security
- Confirm deletion of plans after pre-check and restrict vendor use of uploaded plans.
- Proof of value
- Backtest on past submittals versus staff correction letters
- Track false flags reported by applicants
- Verify deletion practices

Implementation considerations
Lighthouse Advisory interpretation across the operating dimensions a public-sector buyer must settle before this evidence becomes a design. Each note answers the question under its heading for this specific source.
Architecture and integration
What must connect, and where does the AI sit in the workflow?
Applicant-side pre-check sits before the city's permitting system; integration is limited to the FastPass certificate, reducing integration risk.
Governance
Who approves, reviews and stays accountable for outcomes?
Labelling output advisory and keeping the Building Official as final authority separates AI advice from regulatory decisions.
Security and privacy
What data, permissions and controls need testing?
Plans and reports are not stored after pre-check; users confirm rights to share plans.
Accessibility and workforce
Who is affected, and what skills or accommodations follow?
Aims to shift plan checker time from routine omissions to complex review.
Procurement
What should contracts, pricing and exit terms secure?
City pays the vendor so the service is free to applicants; cost and contract terms not disclosed.
Operating model
Which teams own the service once it runs?
FastPass creates a priority lane tied to pre-check use.
