How do I know if I need a jurisdictional inspection?

Most states, counties or cities require periodic inspections of commercial boilers or pressure vessels. The law or regulations may also require a certificate that attests the equipment complies with these requirements. If you answer “yes” to any of the following questions, you may need an inspection:

  • Do you have any heating or process boilers at your location?
  • Do you have any large (200,000 Btuh) water heaters?
  • Do you have any pressure vessels at your location, such as commercial air tanks and hot water tanks?
  • Do you have any air conditioning/refrigeration at your location? (This does not include household refrigerators/freezers or window air conditioners.)
