CBC 11B-233.3.4.2 triggers accessibility requirements when a residential kitchen or bath is substantially altered. I cannot find any code definition of "substantially altered".
The IEBC has Alterations level 1, 2, and 3, but none of those related chapters were adopted in California.
IEBC has a definition of "substantial improvement", that can include "alteration", but I don't see a clear definition of "substantial alteration".
Specific example: I have clients who want to do a "refresh" rehab of existing publicly-funded apartments. this typically involves replacing all kitchen cabinets in-kind, replacing existing toilets with low-flow toilets, and replacing worn-out fiberglass tubs / surrounds and sinks. This is all done due to significant wear and tear. In one sense it is maintenance, a type of glorified "repair". But if the existing kitchen or bath clearances do not meet 11B/ADA, they don't want the refresh to compel structural alterations.
"11B-233.3.4.2 Alterations to individual residential
dwelling units. In public housing facilities with individual
residential dwelling units, where a bathroom or a
kitchen is substantially altered, and at least one other
room is altered, the requirements of Section 11B233.3.1
shall apply to the altered residential dwelling
units until the total number of residential dwelling units
complies with the minimum number required by Sections
11B-233.3.1.1, 11B-233.3.1.2, and 11B-233.3.1.3."
