Yes. CrossBeam Permits drafts plan check corrections letters for city and county building and planning departments, on the agency’s own letterhead and in its format, and staff approve every item before anything reaches an applicant.

## What goes into the draft letter?

CrossBeam Permits reads the full plan set, sheet by sheet, and checks it against the state building code and the agency’s adopted local amendments, and on the planning side against the zoning code and objective standards. Each finding names the code section it rests on and the sheet where the evidence is. A finding that cannot point to both is flagged for a person to look at instead of being stated as a correction.

## Does the letter look like our department’s letter?

The draft letter uses the agency’s letterhead, numbering, phrasing and format, so applicants receive the department’s letter, not a software report. Staff can promote, demote, edit or dismiss any item before signing. Nothing reaches an applicant without staff approval.

## What happens when plans come back?

When plans come back, CrossBeam Permits checks the new set against the prior letter item by item and reports which items appear resolved and which do not. It also flags changes elsewhere in the set that were not part of the response, so the reviewer does not start the review over from scratch.

## Who decides what the letter says?

Agency staff do, on every item. CrossBeam Permits drafts; it does not issue permits, approve plans or make binding determinations. The [AI FactSheet](https://www.crossbeam-permits.com/ai-factsheet) explains human oversight, data handling and security in the GovAI Coalition format.

| Stage | What CrossBeam Permits drafts | Who decides |
| --- | --- | --- |
| Applicant pre-check (optional, agency-offered) | A list of likely corrections, each tied to a sheet and a code section | The applicant decides what to fix; the agency still reviews every submittal |
| Intake screening | What is required, what is present, what is missing, and a draft notice to the applicant | Permit technician or planner |
| Building and planning plan check | Findings tied to the governing code section and the plan sheet | Plan reviewer or planner |
| Corrections letter | A letter on the agency’s letterhead, in the agency’s format and wording | Plan reviewer signs |
| Backcheck | Item-by-item check of the resubmittal against the prior letter, plus changes elsewhere in the set | Plan reviewer |
| Staff and public questions | Answers grounded in state code and local rules | Staff choose where it is offered |
