City Utility Maps & Records for Manhattan Projects

Utilities and Infrastructure New York 4 Minutes Read · published February 05, 2026 Flag of New York

For projects in Manhattan, New York you must obtain official utility maps and records early in planning to avoid conflicts with water, sewer, gas, electric and communications infrastructure. This guide explains where to request municipal records, which offices enforce rules, typical permit pathways and practical steps to get maps, locate markings and keep compliant documentation before excavation or building work.

Where to obtain utility maps and records

Key municipal sources for utility and subsurface information for Manhattan projects include the Department of Buildings for building and permit records, the Department of Transportation for street-opening and roadway utility permits, and the Department of Environmental Protection for water and sewer records and maps. Use the city online viewers and permit portals as first sources, then request archived records or FOIL copies if needed.

Ask for the most recent plan set and any addenda when you request records.

Practical steps to obtain records

  • Search online viewers and permit portals first to identify existing permits and drawings.
  • Contact the issuing agency if online records are incomplete; request certified copies or FOIL where necessary.
  • Order utility mark-outs (CALL 811 and private utility locates) before any ground work.
  • Retain PDFs of plan sets, stamped drawings and any as-built notes in the project record.

Penalties & Enforcement

Enforcement of record, permit and street-opening requirements is handled by the relevant issuing agency: DOB enforces building code and permit violations, DOT enforces street-opening and roadway work conditions, and DEP enforces water and sewer connections and tampering rules. Civil penalties, stop-work orders and permit revocations are typical remedies; criminal prosecution may apply for intentional damage to infrastructure.

  • Fine amounts: not specified on the cited pages for generic guidance; see the issuing agency pages for statutory schedules and case-specific fines.[1]
  • Escalation: agencies may issue notices of violation, civil penalties and continuing daily fines or revoke permits; specific escalation ranges are not specified on the cited pages.
  • Non-monetary sanctions: stop-work orders, permit suspension or revocation, corrective orders, mandatory remediation, and civil or criminal referral to courts.
  • Enforcer contacts and complaints: file complaints or request inspections through the agency complaint/contact channels; see agency pages for online reporting and phone numbers.
  • Appeal and review: DOB and DOT provide administrative appeal procedures; time limits for filing appeals vary by agency and case type and are not specified on the cited pages.
  • Defences and discretion: permitted work, emergency repairs, authorized variances or waivers may be available depending on permits and approvals.
If you suspect an unmarked utility, stop work and notify 811 and the agency immediately.

Applications & Forms

Most official applications are submitted through agency portals (DOB NOW, DOT permit portal, DEP requests). Specific form names, fee schedules and submission checklists may vary by permit type and are not always published in a single summary on the cited pages; consult the agency portal for the required forms and fees for your permit type.[1]

How-To

  1. Identify the scope of work and which utilities are likely affected (water, sewer, gas, electric, telecom).
  2. Search DOB, DOT and DEP online viewers and permit records for as-built plans and past permits.[1]
  3. Contact agencies for archived records or FOIL requests if online resources are insufficient.
  4. Apply for required permits (street-opening, building permits) via agency portals and confirm required documentation and fees.
  5. Arrange utility mark-outs through 811 and any private utility locators before excavation.
  6. Keep stamped plans, permit conditions and mark-out records on site throughout construction and at final closeout.
