Boiler inspection
Boiler inspections are set by state boiler law, not a national code. A commissioned inspector, from the state or from your boiler's insurer, examines the boiler and its safety devices, and the state issues a certificate of operation once fees are paid.
How often depends on the boiler. In Texas, power boilers are inspected every year, heating boilers every two years and hot water supply boilers every three. Florida inspects only boilers in places of public assembly.

What the code asks for
- Applies when
- A steam or hot water boiler in a commercial building, where state boiler law applies.
- What the pro does
- A commissioned boiler inspector examines the boiler and its safety devices (and inside, where the type allows) and reports to the state.
- Who may do it
- An inspector commissioned by the state, employed by the state or by the boiler's insurance company.
- Your own checks
- Keep the certificate of operation posted and the boiler room clear.
- No filing step
- There is no national code. The state boiler law sets intervals and which boilers are exempt, so use the state entry. Texas and Florida are shown below as examples and differ (Florida inspects only boilers in public assembly buildings).

NFPA sells its codes rather than publishing them, so these are fire and health authorities quoting the code. They are national code, not rules for that city or state.
| Case | How often |
|---|---|
| Power and high pressure boilers (typical state rule) | Every year |
| Heating boilers (Texas and Florida use 24 months) | Every 2 years |
| Hot water supply boilers (Texas: 36 months; Florida: 24 months) | Every 3 years |
What it costs to miss
- Texas charges a late inspection fee of $25 a day for the first 30 days, then $50, then $100, to both the owner and the inspection agency.
