Cited law label: 28-118.3.242 associated source record(s)
Scenario vs. completed case: This guide is derived from enforcement allegations in a DOB-ECB dataset; it does not claim a client outcome, dismissal, permit issuance or verified site history. Narrative fields in the export are truncated, so full summonses must be checked before drawing case-specific conclusions.

What this enforcement scenario describes

This scenario concerns illegal cellar dwelling or apartment, associated in the source export with 28-118.3.2. The source data describe allegations—not independently verified findings or completed client projects.

How to evaluate this particular condition

Compare the described cellar rooms and equipment with the legal occupancy record and evaluate egress, light and fire safety implications.

Potential correction approach

Evaluate lawful restoration of approved use or a feasible legalization pathway with an architect and other licensed professionals. The legally appropriate path may differ with permit history, physical site conditions, applicable code edition and the wording of the actual summons.

Evidence to start assembling

Certificate of occupancy, approved plans, restoration photographs and professional documentation. Keep originals, date photographs, and check that the supporting records address every listed condition.

Questions worth resolving before filing

Specific clues in the enforcement descriptions

These are text indicators extracted from the source records for this precise law-and-scenario combination. They show what inspectors mentioned, not whether the allegation was proven or how a property was ultimately corrected.

Severity labels found in this subset: CLASS - 1 (25), CLASS - 2 (17). Severity depends on the actual summons; it cannot be determined from a topic title.

Occupancy and approved-use review for 28-118.3.2

Read the Certificate of Occupancy, approved plans and building records first. The corrective approach may require removing unlawful living arrangements, restoring a legal layout, or testing feasibility of an approved change. Do not assume a permit can legalize an unauthorized unit.

General DOB/OATH resolution pathway

  1. Identify the controlling documents. Locate the actual summons, inspector narrative, cited rule, OATH hearing date and any related DOB orders. The same code label can cover distinct situations.
  2. Address immediate risks. If the condition poses a safety threat or is subject to a stop-work or vacate order, comply with applicable restrictions and obtain appropriate professional assistance promptly.
  3. Select a supportable corrective approach. That may involve stopping a use, repairing or removing unauthorized work, obtaining permits, inspections or professional evaluation. Legalization is not assured.
  4. Separate hearing response from DOB correction. Respond to OATH as required. A payment or hearing outcome does not automatically establish that all DOB correction requirements are satisfied.
  5. Document and certify correction. Where required, submit the Certificate of Correction through DOB NOW: Safety → Violations & Notices of Deficiency, including the proper attestations and applicable evidence. Monitor DOB status after submission.
