Code: LAA (official acronym)
Description: means (Limited Alteration Application). It is a DOB filing for small, limited work on some building systems, not for major construction.
Practical Meaning: A filing used for limited repair or replacement work on certain existing systems, such as plumbing, fire suppression piping, or oil burner installations.
Where You May See It: On DOB filings, contractor paperwork, permit records, or violation correction documents.
Why It Matters: If your home has plumbing or similar system work, an LAA may be the correct DOB filing for the contractor to use so the work is legal and can be signed off properly.
