Limited Alteration Application (LAA)

 

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 a LAA1 Form:

  • 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.

The LAA must be signed and sealed by the Licensed Contractor, and include all applicable filing fees, at the time the application is submitted.

LAA1: can be filed in person or by mail to:

New York City Department of Buildings
Limited Alteration Application/Permit Renewal Unit
280 Broadway, 5th Floor
New York, NY 10007
9:00 am to 4:00 pm (M - F)

OR

Through the NYC Development Hub & Electronic Filing System

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). 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 (LAA1).
