An encroachment permit authorizes work within the public right-of-way (ROW) — the portion of the street, sidewalk, and roadside area owned and maintained by the municipality or state. Any activity that disturbs, occupies, or modifies the public ROW requires an encroachment permit. This includes utility connections, driveway construction, frontage improvements, tree removal, temporary construction access, and even placing a dumpster in the street.

What Requires an Encroachment Permit

  • Utility connections — connecting the on-site storm drain, sewer lateral, or water service to the public main in the street
  • Driveway approaches — constructing or modifying the concrete driveway approach between the curb and the property line
  • Frontage improvements — constructing or reconstructing sidewalk, curb and gutter, street paving, or streetlights along the project frontage
  • Street cuts — cutting into the street pavement for any purpose (utility installation, repair, potholing)
  • Temporary closures — closing a lane, sidewalk, or parking space for construction access, crane operations, or material staging
  • Landscaping in the ROW — planting street trees, installing irrigation, or modifying the planting strip between the sidewalk and the curb
  • Signage or structures in the ROW — A-frame signs, outdoor dining platforms, awnings that extend over the sidewalk (in some jurisdictions)

The Permit Process

  1. Application — submit the encroachment permit application to the public works or engineering department, typically with a plan showing the work, the limits of disturbance, and the traffic control plan (if applicable).
  2. Plan review — the public works engineer reviews the proposed work for compliance with the municipal standard specifications and details. Typical review time: 2 to 4 weeks.
  3. Fee payment — encroachment permit fees include a plan review fee, an inspection fee, and sometimes a pavement restoration deposit. Fees vary from $500 for a simple utility connection to $5,000+ for major frontage improvements. Some jurisdictions charge a per-square-foot fee for pavement cuts.
  4. Insurance — the permittee (typically the contractor) must provide proof of liability insurance, often with the municipality named as an additional insured. Minimum coverage is typically $1,000,000 per occurrence.
  5. Permit issuance — once approved, the permit authorizes the work for a specified duration (typically 30 to 90 days). Extensions may be available for additional fee.
  6. Inspection — the public works inspector visits the site during and after the work to verify compliance. Failed inspections require corrective work and re-inspection.
  7. Restoration — the permittee must restore the ROW to its original condition (or better). For street cuts, this typically means a full-width pavement grind and overlay (T-cut) or a trench patch per the municipality's pavement restoration standard. Some jurisdictions require a permanent patch within 30 days of the temporary patch. The pavement restoration deposit is refunded after the permanent restoration passes inspection.

Traffic Control

Any work that affects vehicle or pedestrian traffic in the ROW requires a traffic control plan. The plan must comply with the Manual on Uniform Traffic Control Devices (MUTCD) and the municipality's traffic control standards. Requirements include:

  • Advance warning signs (ROAD WORK AHEAD, LANE CLOSURE AHEAD)
  • Channelizing devices (cones, delineators, barricades) to guide traffic around the work zone
  • Flaggers at lane closures if traffic cannot be safely self-guided
  • Pedestrian detour routes if the sidewalk is closed
  • Compliance with permitted work hours (many jurisdictions restrict ROW work to 8 AM to 5 PM on weekdays)

The traffic control plan is usually prepared by the contractor and submitted with the encroachment permit application. For major work (full street closures, multi-day lane closures on arterials), the municipality may require a traffic management plan reviewed by the traffic engineering division, which adds 2 to 4 weeks to the approval timeline.

Coordination with the Improvement Plans

For most development projects, the frontage improvements and utility connections are shown on the improvement plans (the civil engineering drawings for public improvements). The improvement plans are reviewed and approved by the public works department as part of the building or grading permit process. The encroachment permit for the actual construction work is issued separately, after the improvement plans are approved.

Do not assume that approved improvement plans equal an approved encroachment permit. They are separate documents with separate approvals. Apply for the encroachment permit as soon as the improvement plans are approved, so that the permit is in hand when the contractor is ready to work in the ROW.

Common Problems

  • Working without a permit. This triggers a stop-work order, a penalty fee (typically double the normal permit fee), and potentially a code enforcement case. Never work in the ROW without a permit.
  • Insufficient pavement restoration. A trench patch that sinks or cracks within the maintenance period (typically 1 to 2 years) must be repaired at the permittee's expense. The pavement restoration deposit is held as security for this.
  • Traffic control violations. OSHA, the municipality, and law enforcement all have jurisdiction over work zone safety. Fines for traffic control violations range from $500 to $10,000+.
