What does pre-war mean on this NYC landlord page?

The filter includes landlords whose portfolios are mostly buildings put up before 1947. It describes the age of buildings in a landlord’s portfolio, not the condition of any particular apartment.

Does every building in a listed landlord’s portfolio predate 1947?

No. The filter is based on a portfolio that is mostly made up of buildings constructed before 1947. A landlord may also have buildings from other periods.

How can I check whether a specific NYC building is tied to a landlord here?

Look for the address in the landlord’s portfolio and compare it with building records. Confirm the ownership or management relationship before relying on it in your rental decision.

Does a pre-war listing tell me whether an apartment is in good condition?

No. The filter refers to the age of buildings in a landlord’s portfolio, not the condition of an individual apartment. Review records and information about the specific property, and inspect the unit before signing.

Can this page show how a landlord handles maintenance in pre-war buildings?

Openigloo records can give you information to review about landlords and their buildings, but the pre-war filter itself does not measure maintenance. Look for property-specific records and renter accounts when assessing maintenance history.

Why might a landlord on this page also have newer buildings?

The filter applies when most of a landlord’s portfolio consists of buildings put up before 1947. It does not require every building in the portfolio to meet that definition.

Landlords with pre-war buildings in NYC

241,661 landlords with pre-war buildings in NYC appear in Openigloo's records, each with a portfolio and an open-data history. Use this list to identify owners and managers whose portfolios are mostly made up of buildings constructed before 1947. That can help you focus your research on the people responsible for older properties and check whether a specific building is part of their portfolio.

Compare building records and renter experiences for the property you are considering, rather than relying on a landlord’s overall history alone. The pre-war label describes the age of buildings in a portfolio; it does not confirm the condition of a particular apartment or predict how a manager will handle future issues. Verify details that matter to your lease directly.
