About this catalog

What does this building code catalog cover?

The catalog organizes MeltPlan adoption records by model code publication and links to state-level adoption details, effective dates, amendment types, and official references where available.

Does a statewide record prove that a code applies to every project?

No. Local amendments, home-rule jurisdictions, project type, occupancy, and enforcement dates can change which requirements apply. Confirm the final code set with the authority having jurisdiction.

How should zero-record codebook pages be interpreted?

A zero means the current MeltPlan dataset has no active statewide adoption record under that code identifier. It does not prove that no local jurisdiction uses or references the publication.
