AHJ Radar watches the fire, building, elevator, boiler, pool and workplace rules that govern your property, from federal to city, and tells you what changed, when it's due, and who reviewed it, before the inspector does. Built for chief engineers, directors of engineering, property managers and risk teams.
Year built, stories, use and distance to the coast decide which laws reach this address. Nothing else is needed.
Each sweep that finds something material posts a bulletin here. Members open the full brief.

Nobody teaches this on the job. Start with the inspector list above, then open what you need: the editions ahead, a decoder for any citation, the claims people repeat, and who to call.
Model codes move on three-year cycles. "Expected" years follow the publisher's cycle and are not adoption dates; each state adopts on its own schedule, usually one to three years after publication. Adopted dates on this page are verified per state above.
Common citations for hotels and large buildings. Paraphrased; the inspector's report and the code text govern. Not legal advice.
Thirty claims we hear most. Each answer names the rule that decides it. When a claim is "depends," it says what it depends on.
One address, every authority that can cite it, and a record of who saw what. Cancel anytime. Public pages stay free.

The authority having jurisdiction: the fire marshal, the building official, the state licensing board, the county inspector, or a federal agency. Any organization with legal power to enforce a code against your building. Most buildings answer to several at once.
Usually both. Most states adopt a statewide building code and fire code; counties and cities enforce them and can add stricter local rules, such as Miami-Dade's recertification, New York City's facade cycles or Los Angeles' retrofit ordinances. Where they differ, the stricter requirement governs. Model codes are republished every three years and each state adopts a new edition on its own schedule, so the edition in force is a state-by-state fact.
It depends on the state. Elevators are licensed by a state agency (a licensing department, a labor department or the fire marshal) or, in a few large cities, by the city itself. Boilers are certified by a state boiler program or by insurance-company inspectors it authorizes; a handful of states have no statewide program and leave it to cities. Every state page on this site names the office.
November 20, 2026 for substances (labels, written program, training) and May 19, 2028 for mixtures, per 91 FR 1695. It applies to every employer in every state, including state-plan states, which enforce it through their own agency.
OSHA penalties run up to $16,550 per serious violation and per day for failure to abate, and $165,514 per willful or repeated violation, at the 2026 amounts. State elevator and boiler programs typically fine per day of operation after a notice, plus reinspection fees, and an expired certificate can shut the equipment down. The fine is rarely the largest cost; the shutdown and the insurer's questions are.
No. It reports what changed, when it takes effect, and where it touches your building, with the source document and the name of the person who reviewed it. Applicability is confirmed with your AHJ or counsel.
