For Bay Area contractors, ADU builders and designers
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
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.
Drawn to look right. Submitted. Then reviewed by someone whose whole job is finding what is missing, using a checklist you have never seen.
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.
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
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.
Covering 26 of our 35 review checks. Your score appears as you answer.

The next step
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.
Where the checks come from
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.
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.
