What Is Plan Check?

Last reviewed: September 2026

Plan check is the review a building department runs on construction drawings and calculations before it issues a permit. In much of the western United States, especially California, that permit review is called plan check. Elsewhere the same gate is usually called plan review.

Who runs it
The authority having jurisdiction, through a plans examiner
Also called
Plan review, outside much of the western United States
What is reviewed
Drawings, calculations, and the reports the intake checklist names
Output
A numbered correction letter or marked PDF
Clears when
Responses are accepted on backcheck

Internal QA/QC and constructability review

Definition

Plan check

A plans examiner reads the set against the adopted building, fire, energy, and accessibility codes, plus local amendments, and writes numbered corrections the design team must answer. The permit is not issued until those comments are cleared or accepted with conditions. Plan check is an authority-having-jurisdiction process. The architect's internal drawing review, and a contractor's constructability review, are different passes on the same sheets.

In depth

Why the name shows up on the invoice

California cities, and many jurisdictions that copied their fee schedule, print plan check on the intake receipt, the correction letter, and the resubmittal stamp. A national team that files the same set in another state may see plan review on the portal. The work is still the permit gate.

Using one name in the fee proposal and the other in the comment log makes it hard to tell which comments are the city's and which belong to the owner's consultant. Pick the word the jurisdiction uses, and keep the city's letter in its own file.

What the examiner is actually testing

The examiner is not coordinating the model and is not pricing the job. The review tests whether the documents show a building that can be permitted under the adopted code: occupancy, construction type, egress, fire ratings, accessibility, energy, and the structural and MEP criteria local amendments call out.

A missing site plan, unsealed calculations, or a sheet index that does not match the uploaded files are ordinary first-cycle comments. Those are completeness items. They burn a cycle before anyone reads a stair width.

Comments, response, and backcheck

The city returns a comment letter or a marked set. Each item has a number. The design team answers in writing, revises the affected sheets, and clouds the change. A reply that only says see revised sheet, without saying what changed, usually comes back unanswered.

Backcheck is the examiner's next look. It is aimed at the open comments. A revision that creates a new code problem can still draw a new comment. Deferred items, such as sprinklers or a curtain wall, stay open only if the approved path says they may be submitted later.

Fees, extra cycles, and a set that is not ready

Plan-check fees are often due at intake and sit beside the building permit fee, not inside it. Additional cycles may be billed by the hour or as a percentage of the original fee. The intake checklist is the contract for what must be in the first package.

A set that is still in design development will spend those cycles on missing information. Owners who want a permit date should file a set the examiner can review, with calculations, energy forms, and a response method the portal accepts.

The permit set has to match the approval

Keep the comment letter, the written response, and the revised sheets together. The contractor who builds from a PDF that is not the revision the city stamped is building a delta that was never permitted.

Title each response with the comment number, the sheet, and the action: revised, clarified, or exception requested. That line is what the backcheck reads. The cloud on the sheet should point at the same change.

Examples

Plan check on a real project

  • 01

    A Los Angeles plan checker returns 40 corrections on egress and the energy forms, and the architect answers them on a numbered log before the second cycle.

  • 02

    A Seattle intake reviewer rejects the package because the structural calculations are not sealed, before a plans examiner is assigned.

  • 03

    A resubmittal clouds only the toilet-room dimensions the comment named, and the backcheck clears that item.

FAQ

Frequently asked questions

They are the same permit gate under two names. Plan check is the term used by many western U.S. building departments, especially in California. Plan review is the broader term, and the one ICC documents tend to use. Read the city's own checklist for the name and the required forms.

A plans examiner at the authority having jurisdiction, or a contract reviewer the city has deputized. The architect of record prepares the response. The examiner does not design the fix.

Two or three cycles is common on a straightforward commercial set that was complete at intake. Incomplete packages, deferred items, and discretionary planning conditions add cycles. The fee schedule often prices the later ones separately.

No. The city checks the set against adopted codes. The architect's QA/QC checks coordination, firm standards, and whether the documents say what the design intends. Both can mark the same sheet for different reasons.
