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