Q: What is the difference between an Alteration Type-I Application and an Alteration Type-II Application?

A: An Alteration Type-I Application is required when there is a change to the Certificate of Occupancy of a building, due to an interior conversion of the building or a space within a building, or due to a building addition. Most commonly, an Alteration Type-I Application will be used to change the Maximum Number of Persons for a space, to change the Occupancy or Use Group of a space, and/or to change the Description of a space.

An Alteration Type-II Application may be used when there is no change to the Certificate of Occupancy due to the proposed alterations, such as with an interior fitout or an apartment alteration. When an Alteration Type-II is filed under Directive-14 (such is the case 99% of the time), the Applicant or other NYS Registered PE/RA may signoff the application with a Directive-14 Final Inspection. An Alteration Type-II, Directive-14 Application must include the statement "No Change to Use, Egress, or Occupancy under this Application" on the Title Sheet.
