Limited Alteration Applications


The Limited Alteration Application (LAA) is used for plumbing work, fire suppression piping replacement and repairs, and oil burner installations that do not include construction work. Generally, with the exception of some minor new installations, LAA work is restricted to repair and/or replacement of existing equipment and does not require a Professional Engineer (P.E.) or a Registered Architect (R.A.).

The following Skilled Trades may submit an LAA filing in DOB NOW: Build:

  • Licensed Master Plumbers
  • Licensed Master Fire Suppression Piping Contractors
  • Licensed Oil Burner Installers.

Licensed Master Plumbers can use the LAA1 Form to install minor plumbing work for repairs and replacement appliances.


New Installation Guidelines


Replacement Installation Guidelines

On occasions when a licensee cannot file a LAA, but has to respond to an emergency or hazardous condition, the Contractor may file an Emergency Work Notification (EWN) in DOB NOW: Build. When emergency work is necessary, Licensed Master Plumbers, Licensed Master Fire Suppression Piping Contractors, and Licensed Oil Burner Installers may file an EWN and perform the work prior to filing a Limited Alteration Application.

Emergency work includes

  • Repairs to address an emergency or hazardous condition that needs immediate attention
  • Restoration of gas for cooking purposes in 9 or more residential dwelling units
  • Restoration of heat and hot water
  • Maintain sanitary conditions
  • Restore fire suppression systems to proper working conditions

Licensed Contractors seeking to perform minor plumbing and oil burner installations/repairs or sprinkler and standpipe work can obtain a LAA if the job meets the criteria as a Category 1 or Category 2 limited alteration.

NOTE: Only one category and one work type can be filed per LAA.

With the implementation of the 2014 Code revision the LAA1 now includes:

Category 1 – Limited to an estimated cost of $35,000 per licensee within a 12 month period.
Category 2 – No estimated cost limitation or time period restriction.
