Level 1

An Option 1 inspection is the recommended option when an evaluation of the system for continued service is needed and the conditions of use are not changing. This could include:

  • Routine or annual evaluations of the venting system
  • An appliance connected to the system is being replaced with a similar appliance
  • During chimney cleaning or sweeping

An Option 1 inspection is limited to readily accessible portions of the system, and accessible portions of the appliance(s) and the chimney connection.

The inspector will check the readily accessible portions of chimney, its enclosing structure, and the flue.

An Option 1 inspection includes verification that the flue is not blocked or significantly restricted.

Level 2

An Option 2 inspection is more detailed and thorough than an Option 1 and is the recommended inspection when conditions of use for the appliance or venting system are changing, or when an Option 1 inspection reveals the need for a more detailed inspection. Several instances where an Option 2 inspection is specifically recommended include:

  • Replacement of an appliance with one of dissimilar type, input rating or efficiency
  • Prior to a flue relining
  • Upon sale or transfer of the property
  • After an event likely to have caused damage to the chimney, such as a chimney fire or sudden occurrence event

While the Option 2 inspection is a rather thorough inspection and requires access to many areas of the building, it does not require removal of permanent parts of the building, such as siding, chase covers or coverings.

An Option 2 inspection includes all of the requirements of an Option 1 inspection as well as the following:

  • Inspection of accessible areas of attics, basements, and crawlspaces
  • Accessible areas of the chimney exterior and interior
  • Accessible portions of the appliance and chimney connection
  • Video scanning, or other thorough inspection, of the flue interior
  • Evaluation of the flue lining to determine that its material and sizing is appropriate the appliances being served
  • Proper clearance to combustibles in the accessible areas listed above
  • Proper construction and condition of the chimney system in the accessible areas listed above

Level 3

An Option 3 inspection is the most detailed of all of the inspection types. It includes inspection of concealed areas of the building. However, examination of concealed areas will be limited to areas reasonably suspected of hazards that cannot be evaluated otherwise.

An Option 3 inspection includes all areas covered in an Option 1 and Option 2 inspection, and inspection of concealed areas to investigate known or suspected problems. In as much as certain portions of an Option 3 inspection require destructive action to the building, the inspector will discuss these areas with the building owner prior to the inspection.
