Gilbert wrote a window exemption into its own code rather than borrowing a generic repair clause, and the wording is narrower than it looks. The test is same style window, same opening, egress maintained. Style is the word to watch, because swapping a single-hung for a casement changes it even when the opening is untouched, and Gilbert also runs two code cycles behind its larger neighbors.

Item 13 of Gilbert's amended R105.2 exempts "window replacement with same style window in same opening. Egress requirements must be maintained." That's purpose-built language, and it's cleaner than the "repair in kind" phrasing most jurisdictions borrow from the commercial code.
Style is the word to watch. It's a narrower test than "in kind". Swapping a single-hung for a casement changes the style even when the opening is untouched, and so, arguably, does a change in grid pattern.
Gilbert is a town rather than a city, and its technical codes run the 2018 IBC and 2018 IRC. Neighboring Mesa and Chandler are on the 2024 family. A local amendment to IBC 2406.4.5 also requires all glazing in bathrooms to meet safety glazing, with no exception.
Gilbert's exemption turns on style rather than on the looser in-kind test, so the first question is about the window type.
Not if the exemption fits. Item 13 of Gilbert's amended R105.2 exempts window replacement with the same style window in the same opening, with egress requirements maintained. It is purpose-built language rather than the in-kind phrasing most jurisdictions borrow from the commercial code.
Narrower than in kind. Swapping a single-hung for a casement changes the style even when the opening is untouched, and a change in grid pattern arguably does too. Confirm with the building department before ordering if the type is changing.
The 2018 IBC and 2018 IRC. Neighboring Mesa and Chandler are on the 2024 family, so guidance written for either of those does not describe Gilbert.
Yes. A local amendment to IBC 2406.4.5 requires all glazing in bathrooms to meet safety glazing, with no exception.
Yes. The exemption is conditioned on egress being maintained, so a bedroom window that loses clear opening to a thicker frame can fail even on a same-style swap.
