1. Property Records Identify Ownership and Recording Issues
Property listings may omit information that affects ownership and transfer rights. Before signing, buyers should compare recorded property documents with the seller's representations and transaction paperwork. Public records provide useful information, but they do not replace a title examination.
Verify Ownership and Recorded Documents through ACRIS
The Automated City Register Information System (ACRIS) provides online access to deeds, mortgages, and other recorded documents dating back to 1966.
Buyers should compare the recorded owner's name, property description, and borough-block-lot identification with the purchase agreement. Older documents require a separate records-library search.
Discrepancies may require further investigation before closing.
Identify Mortgages, Liens, and Recording Problems
Outstanding mortgages and recorded liens may complicate property transfers. New York Real Property Law § 291 addresses priority between competing conveyances, including circumstances where a qualifying subsequent purchaser acts in good faith, gives value, and records first.
A title examination can help identify relevant encumbrances, ownership transfers, and recorded satisfactions. Buyers can also review land title recording requirements to understand potential recording disputes.
Recognize the Limits of Public Ownership Records
ACRIS does not establish marketable title or identify every ownership restriction. Cooperative apartments generally involve corporate shares and a proprietary lease rather than a deed to an individual unit.
Cooperative buyers should examine the share documents, proprietary lease, and applicable corporate restrictions before proceeding.
2. Building Records Show Approved Uses and Outstanding Issues
A property's physical layout does not necessarily reflect its legally approved occupancy. Department of Buildings (DOB) records provide information about permits, violations, and authorized uses. Zoning and landmark restrictions may impose additional requirements on proposed alterations.
Compare the Certificate of Occupancy with Actual Use
A Certificate of Occupancy (CO) identifies a building's approved use and occupancy. Buyers should compare the certificate with the property's actual layout and advertised number of dwelling units.
Buildings constructed before 1938 may be exempt from the CO requirement unless later alterations changed their use, egress, or occupancy. For an exempt building, a Letter of No Objection may confirm lawful use.
The absence of a CO alone does not establish an illegal occupancy.
Review Permits, Complaints, and Open Violations
The Buildings Information System (BIS) and DOB NOW Public Portal contain different portions of a building's permit and enforcement history. BIS also contains complaints and certain violations unavailable in DOB NOW.
A permit application does not establish completed, approved work, and a complaint does not necessarily prove a violation. Owners should verify outstanding violations, required corrections, and completed approvals.
Examine Zoning and Landmark Restrictions
The NYC Zoning Resolution governs permitted land uses and development. A proposed use may satisfy zoning requirements but still require DOB permits or occupancy approval.
Buildings within designated historic districts may also require Landmarks Preservation Commission approval for certain exterior work. Owners should review applicable land use and zoning requirements before starting construction.
3. Record Discrepancies Call for Document-Specific Responses
Discrepancies involving ownership, occupancy, or building compliance may affect contractual obligations and property use. Available remedies depend on the defect, applicable law, and transaction documents. A recorded violation does not automatically establish a right to terminate a contract or recover damages.
Address Property Problems before Closing
Buyers should compare title reports, building records, and inspection findings with the purchase agreement.
Undisclosed mortgages, ownership discrepancies, or unauthorized alterations may require corrective documents, further investigation, or negotiations before closing.
Contractual contingencies and cure provisions affect the available options. Discovering a defect does not automatically authorize cancellation without financial consequences.
Confirm Rental Status and Lawful Occupancy
Tenants should compare a rental unit's advertised use with available occupancy records. HPD Online provides housing complaints, violations, and property registration information.
Rent regulation requires separate verification. Tenants may request apartment rent registration histories from New York State Homes and Community Renewal.
These histories reflect owner-reported information and may not conclusively determine rent stabilization coverage. A landlord's market-rate designation is also not conclusive.
Additional information appears under New York tenant rights.
Preserve Documents That Explain the Discrepancy
Parties should retain records that establish ownership, building conditions, and representations made during the transaction.
Relevant documents include:
- Deeds, mortgages, and title reports.
- Occupancy certificates and permit histories.
- Building complaints, violations, and inspection records.
- Purchase agreements, leases, emails, and photographs.
Preserve original documents when possible and record when each item was obtained. These materials may help establish what the parties knew when a disagreement arose.
4. Property Disputes Follow Different Filing Paths
Building violations, housing maintenance complaints, ownership disputes, and landlord-tenant proceedings involve different authorities. The appropriate process depends on the legal issue and requested remedy. Administrative complaints and court actions also have different procedural requirements.
Building and Housing Complaints Involve Different Agencies
The NYC Department of Buildings investigates suspected illegal conversions, unauthorized construction, and certain occupancy violations. Complaints may be submitted through NYC 311.
The Department of Housing Preservation and Development (HPD) addresses housing maintenance conditions and related enforcement matters.
Agency enforcement does not automatically resolve contractual claims or disputes over possession. Those matters may require separate legal proceedings.
Identify the Proper Kings County Court
Kings County Housing Court, located at 141 Livingston Street, handles landlord-tenant proceedings and certain housing-related claims.
Kings County Supreme Court, Civil Term, located at 360 Adams Street, may hear ownership, title, and other real property disputes requiring relief outside the authority of lower courts.
The appropriate court depends on the claims and requested remedies. Filing, service, and procedural deadlines must be evaluated separately.
Additional options are discussed under real estate dispute resolution.
Distinguish Local Property Rules from Federal Protections
New York law generally governs deed recording and property ownership, while NYC regulations address building occupancy, zoning, and local enforcement.
The federal Fair Housing Act separately prohibits specified forms of discrimination in covered residential sales, rentals, and related housing activities.
These legal frameworks address different issues. Affected parties should identify the applicable requirements, responsible authority, supporting records, and available filing procedure before pursuing a claim.
