Pennsylvania is the state-adopted case east of the Rockies: the Uniform Construction Code incorporates the 2021 IWUIC, effective 2026-01-01, and fourteen exact product paths from its Classes 1–3 are documented here. What applies to your house starts from a statewide wildfire book, not a local option.
What the book cannot decide from Harrisburg — the official map, your assigned class, your project's scope, and the final confirmation — is exactly the list at what we can't tell you yet.
The plant file matches the code file in weight: 879 records documented across USDA half-zones 5b through 8a, with 204 flagged invasive or noxious. Living here balances the page.
What applies in Pennsylvania
Pennsylvania’s Uniform Construction Code incorporates the 2021 IWUIC, effective 1 January 2026. Fourteen exact product-semantic paths from Classes 1–3 are normalized here; the official map, assigned class, project scope, and building-official confirmation still decide what applies.
State distribution, native range, invasive status, hardiness, and fire evidence answer different questions. None is a planting approval. The list itself is on Grow — this page carries the aggregates.
For Pennsylvania Firewise committees, fire districts, and HOA architectural
committees. The frame stays current as the evidence does, so it does not
go stale the way a copied PDF does. Free to use with the attribution line
