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 a LAA1 Form:

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