What If Plan Check Returns Title 24 Corrections on a House?

The mismatch corrections

The most common comment is not about the design at all. The window schedule on the drawings lists sizes or performance values the calculations were not run on; the mechanical schedule names different equipment; an assembly changed after the forms were issued. Two documents in the same submittal describe different buildings, and the plan checker is pointing at the gap. Reissuing the compliance set against the current drawings clears it.

The correction that is specific to existing houses

Where a report relied on assumptions about the existing construction, a plan checker may ask what those assumptions were based on. This is a fair question and it has a real answer: either the existing condition was established and can be stated, or code default assumptions for the vintage of the house were used, which is a legitimate route.

Occasionally the checker's own knowledge of local building stock conflicts with the default, and the resolution is to verify the actual condition — opening up a small area, or confirming from a previous permit record — rather than to argue the assumption.

The corrections that need a decision

A smaller number are real: the design as drawn does not meet the requirement. On houses this is usually glazing, either its performance or its area against the addition cap. Here the response is a choice rather than a resubmittal — better glazing, less of it, more insulation, or better equipment. Those cost very different amounts, which is why the options are worth setting out before one is picked.

What to send

The correction letter in full rather than summarised, because comments are numbered and answering the exact comment is what clears it, and the drawing set as it now stands. Revisions are unlimited until the project complies, so however many rounds of comments come back, each one is covered.
