Is AI plan review legal?

Who makes the plan review decision when AI is used?

The agency does. The building code gives the building official the duty to examine construction documents and approve or reject them, and agencies carry out that duty with their own staff or with consultants they engage. CrossBeam Permits does not change who holds that authority.

• CrossBeam Permits produces a draft: findings, a draft corrections letter, a completeness notice.
• A plan reviewer or permit technician at the agency reads each item and decides to keep, edit, promote, demote or dismiss it.
• Nothing reaches an applicant as an agency decision until staff approve it.
• CrossBeam Permits does not issue permits, approve plans or make binding determinations.

Agencies using CrossBeam Permits say the same in their own documents. The City of Laguna Beach staff report states: “Every AI-generated review will continue to be evaluated by qualified City staff before comments are issued.” Laguna Beach staff report, August 4, 2026. The City of Buena Park’s program page says its pre-check is advisory, that City plan check staff still review all plans, and that the Building Official makes the final permit decisions.

How does CrossBeam Permits show its work?

Every finding cites two things: the code section it rests on, and the plan sheet and location that are the evidence. A reviewer can open the code section and the sheet and check the finding directly instead of trusting the software. If CrossBeam Permits cannot ground a finding in both, it does not state it as a correction. It flags the item for a person to look at.

Which code does it cite?

The code the agency has adopted: the state building code as the floor, plus the agency’s adopted local amendments, and for planning review, the agency’s zoning code and objective standards. The rules are built from published law, so each requirement traces to a public source. The AI FactSheet describes how code updates are tracked and reviewed before they take effect.

Does using AI change our records obligations?

CrossBeam Permits can treat prompts, inputs and outputs for an agency’s work as records the agency may need to retain and produce, with retention set by the agency. Whether and how public records law applies is for your agency’s counsel and records officer to decide.

What about our agency’s AI policy?

Many agencies now have AI policies that require meaningful human oversight, staff review of AI-generated content, and disclosure. CrossBeam Permits publishes an AI FactSheet in the GovAI Coalition format and will complete the agency’s own AI questionnaire. CrossBeam Permits can add an AI-assistance disclosure to generated work product in wording the agency approves.

What should we ask our counsel?

• Does our municipal code or building code adoption ordinance say anything about who may examine construction documents, and does staff review of AI drafts fit it?
• Does our AI policy require disclosure on corrections letters or applicant-facing reports?
• How should AI prompts, inputs and outputs be retained under our records schedule?
• If we offer an applicant pre-check, how should we describe its advisory status to the public?
