Code: LPC (government agency)
Description: This is a New York City agency (Landmarks Preservation Commission) that protects landmark buildings and historic districts and must approve many changes before work starts.
Practical Meaning: If your building is a landmark or in a historic district, this agency must approve many exterior changes, and sometimes interior work, before you start. Doing work without this approval can lead to violations, fines, and being forced to undo or redo the work correctly.
Where You May See It: You may see this name on DOB letters or permits when a project also needs landmark approval, on violation notices about unauthorized work on landmark buildings, or in city records and title reports that mention landmark status. You may also see it on Portico (the landmark permit system), on city websites explaining historic districts, or in emails from architects and expediters.
Why It Matters: If you ignore this agency when your property is landmarked, you may face daily penalties, enforcement cases, and delays in DOB permits until the landmark issue is fixed. Banks, buyers, and insurance companies may ask about landmark status and open landmark violations, so unresolved issues can affect refinancing, resale, and project timelines.
