When You Need a Permit

Most structural changes, work affecting egress, major plumbing or electrical alterations, and conversions of dwelling units require permits under New York City rules. Smaller cosmetic work may be exempt but check project scope against the Department of Buildings guidance before starting work.

  • Submit plans and documents that clearly show scope, materials, and licensed professionals involved.
  • Confirm design professionals (architect or engineer) sign and seal required filings when structural or code compliance issues are present.
  • Schedule required inspections after permit issuance; do not start covered work before approval.
Always verify permit type early to avoid stop-work orders or penalties.

Typical Timeline Considerations

Review timelines vary with permit type, plan complexity, and backlog at the Department of Buildings. Expedited reviews may be available for specific filings or using DOB NOW services; check the official portal for current processing notes.[2]

  • Pre-application research and document collection: days to weeks, depending on complexity.
  • Plan review: variable; check DOB NOW for processing status and possible corrections.
  • Inspections after permit issue: scheduled per inspector availability.
