Your plans came back with corrections. Again.

The job is sitting. The client is calling. And the list from the city is mostly things that could have been caught before it was ever submitted. This is a two-minute X-ray of your set, scored against 35 checks a California residential plan reviewer actually runs.

Why this exists

A correction cycle costs more than the correction.

Most items on a plan-check correction letter take minutes to fix. What they cost is the round trip: back to the designer, back in the queue, back to the client to explain the delay. The fix is cheap. The cycle is not.

Where most sets are

Drawn to look right. Submitted. Then reviewed by someone whose whole job is finding what is missing, using a checklist you have never seen.

Where you want to be

The set is run against that checklist before it goes in, by someone who has read correction letters from the same counters, and the gaps are closed while it is still cheap.

The honest question

What have you already tried that did not work? Most builders tell us the answer is "I asked the designer to double-check it." That is not a checklist. That is a hope.

The X-ray

Twelve questions about the set you are about to submit.

Answer honestly. Nobody sees this but you. "Not sure" is a real answer and it is scored as real exposure, because a set nobody can vouch for is a set nobody has checked.

The next step

Get the same 35-check review run on your actual drawings.

The X-ray above is a self-report. It tells you where you are probably exposed. It cannot see your set. A real review reads the sheets, finds what is actually there, and hands you the corrections in the order a plan checker will raise them.

What the free X-ray gives you
  • Your readiness score
  • Which check families you are exposed on
  • The severity of each exposure
What a real review gives you
  • Every finding, sheet by sheet, with the code section
  • The exact note or detail that closes it
  • What this specific city has commented on before
  • A resubmittal-ready set, not a list

Your answers above are attached so the reply is about your project, not a brochure. One reply from a person. No list, no sequence, no sharing your details.

Where the checks come from

Not a generic checklist. A rulebook built from real correction letters.

Every question above is derived from a written rule with a severity, a risk weight and a measured fix time. The rulebook is the firm's own, last revised 2026-08-03, and it grows every time a city raises something we had not already recorded.

What these numbers are, and what they are not

  • The 35 checks are real and written down. You are welcome to ask what any one of them says.
  • The risk weight on each check is our declared judgement from reviewing sets and reading correction letters. It is not a published municipal statistic, and this page will never dress it up as one.
  • The rework minutes are our own measured drafting time to close each item. Your drafter may be faster or slower.
  • The 15 recorded corrections are from real projects only. Our own test fixtures generate correction records too, and they are excluded from this figure. A number that counts a firm's practice runs as experience is not a number.
  • This X-ray does not predict your city's review timeline. Nobody can, and anyone who puts a number on it is guessing.

If a claim on this page cannot be traced to a rule in that book, it does not belong here. That is the same standard the drawings are held to.
