Oil Tank Removal, Temporary Out of Service or Abandonment for 1 and 2 Family Homes and Townhouses  (I-07-18)

Per IRC section M2201.7, the building official is responsible for issuing permits and verifying compliance with the requirements for whichever method was chosen under this section – removal, temporary out of service, or abandonment.

The building official is only responsible for compliance with the requirements in the Connecticut State Building Code. As with other peripheral issues under the authority of others, such as an OSHA safety violation, if the building official observes something improper he should bring it to the attention of the authority with jurisdiction over the issue.

This is permitted by Section R802.5 of the Connecticut Amendments.
