TL;DR
The International Residential Code is the consolidated model code for one- and two-family dwellings and townhouses up to three stories, bundling structural, plumbing, mechanical, electrical, and energy provisions in one book so a house can be permitted without juggling separate codes. Its prescriptive tables, joist spans, deck ledger fastening, stair geometry, footing depths, are the rules inspectors quote on residential jobs.
What it means
The International Residential Code is the consolidated model code for one- and two-family dwellings and townhouses up to three stories, bundling structural, plumbing, mechanical, electrical, and energy provisions in one book so a house can be permitted without juggling separate codes. Its prescriptive tables, joist spans, deck ledger fastening, stair geometry, footing depths, are the rules inspectors quote on residential jobs. States adopt specific editions with amendments, and its Appendix deck provisions and braced-wall rules shape most contractor disputes over what code actually requires.
