1. The evidence submitted establishes that all the work claimed to have been done was as a coordinated
project and was satisfactorily completed; and
2. Each item of work was either an “improvement” or an ordinary repair and maintenance that was done in
connection with, and as a necessary component, of an allowable IAI. Even such coordinated projects are
best supported by itemized proof and the absence of such itemization, may result in additional scrutiny
or denial. When proof is not adequate in DHCR’s view, such IAI increase may be denied in its entirety
or the difference between the claimed cost and the substantiated cost will be disallowed depending on
the result of DHCR’s review of the documentation.
VI. USEFUL LIFE
An owner who receives an increase for an IAI is not entitled to a further increase based upon the installation
of similar equipment or furniture within the useful life of such equipment or furniture. Unlike major capital
improvements, which have a useful life schedule, DHCR’s determination of whether an IAI’s useful life has
been met will be based on the facts of each case.
Where the useful life of an IAI is at issue and the installation was completed during a vacancy or included on
a vacancy lease, DHCR may require the owner to submit documentation to prove that the useful life of the old
equipment or furniture had been exhausted.
VII. IDENTITY OF INTEREST/COMMON OWNERSHIP
Costs for an IAI paid to a person or organization sharing common ownership or an identity of interest with the

owner or managing agent will be disallowed.
