In New York City, the apartment is only half of what you are buying. A full-floor residence on Fifth Avenue or a penthouse in a new Tribeca condominium sits inside a building whose condition, finances and legal history will shape your costs and your daily life for years. Brokers will show you the views. The building’s record is something you have to look up, and in New York most of it is public.
Experienced buyers and their attorneys increasingly read that record before making an offer rather than after a contract arrives. City data is spread across several agencies, but tools such as Weverit gather the main housing and building records for any address in one place, which makes a first review a matter of minutes. Here is what to look for and what to ask.
The façade: a five-year inspection cycle
Under the Department of Buildings’ Façade Inspection & Safety Program, often called Local Law 11, buildings taller than six stories must have their exterior walls inspected every five years by a qualified professional, with a report filed with the DOB. Each façade is classified as Safe, Safe With a Repair and Maintenance Program (SWARMP), or Unsafe.
An “Unsafe” classification requires immediate public protection, often a sidewalk shed, which must stay in place until the DOB approves the required follow-up filing. A SWARMP classification means repairs must be completed by the deadline stated in the report. Either way, façade work can be a significant capital expense. A prewar building with ornate masonry may face very different costs than a newer glass tower of similar height.
Ask: the most recent façade classification and filing date, and whether any required work is planned and budgeted.
Local Law 97: emissions limits and penalties
Most buildings over 25,000 square feet are subject to carbon emissions limits under Local Law 97. For buildings that exceed their limit, the annual penalty is calculated by multiplying the emissions above the limit by $268 per metric ton of carbon dioxide equivalent. The limits tighten in later compliance periods.
For a buyer, this is a budgeting question. A building that relies on older heating systems may face penalties, a costly retrofit, or both. Either can affect the building’s operating budget, reserves or future assessments, depending on its finances and governing documents.
Ask: whether the building filed its annual emissions report, whether it was within its limit, and what compliance plan the board or management has adopted.
Gas piping: a four-year inspection requirement
Under Local Law 152, most buildings with gas piping must have it inspected periodically, generally every four years, by a licensed master plumber, with certification filed with the DOB. If an inspection finds unsafe conditions, they have to be corrected, and depending on the findings that can involve shutting off gas service while repairs are made.
Ask: the date of the last inspection and whether any conditions were found and corrected.
Housing complaints and violations: look for the pattern
For residential buildings with three or more apartments, the Department of Housing Preservation and Development (HPD) keeps two separate kinds of records. A complaint is a report that a problem exists. A violation is a condition the city has formally cited. Violations come in three classes: A (non-hazardous), B (hazardous) and C (immediately hazardous).
A handful of minor violations in a large building means little on its own. What experienced buyers look for is a pattern: heat and hot water complaints every winter, recurring leaks, or Class C violations left open for months. A recurring pattern can reveal more about maintenance and management than another amenity on the listing.
Building permits and DOB records
The Department of Buildings tracks permits, complaints and enforcement actions. An open permit does not, by itself, prove that work is dangerous or even still underway. What matters is its status, whether the work was ever signed off, and whether related complaints or violations exist. Stop-work orders or repeated complaints about unpermitted work deserve a clear explanation from the managing agent. If you plan a major renovation, a building with a clean permit history is worth noticing.
Recorded documents: ACRIS
The city’s property records system, ACRIS, lets you search recorded documents such as deeds and mortgages. For a condominium unit, it can help trace the ownership chain and identify liens formally recorded against the property. It is a document registry, not a complete or live debt report, and co-op ownership, which is held through shares rather than deeds, works differently. In a new development, recorded sales can give a rough sense of how many units have closed, but they are no substitute for asking the sponsor and reviewing the offering plan.
311: the building’s day-to-day life
311 complaints capture what inspections often don’t: noise, heat outages, construction at odd hours, sanitation. Read them as a timeline. A spike during one long renovation tells a different story than a steady run of heat complaints every January.
Reading the record, not just the listing
None of these signals is disqualifying on its own. Older buildings have histories, and well-run ones deal with issues openly. The point is to start negotiations knowing what the board and managing agent already know, so your attorney’s questions are sharper and potential assessments are part of your math rather than a surprise later.
For readers new to New York’s systems, this primer on the difference between HPD and DOB violations is a useful place to start before reading any building’s record.
