Utility-Specific Installation Permits
Each utility—such as water, sewer, electricity, gas, and telecommunications—requires a dedicated permit for installation. These are typically obtained through the local building department or directly from the utility provider, depending on jurisdiction.

• Water and sewer connection permits for tapping into public systems
  
• Electrical and gas permits for transformer installation, service panels, and meters
  
• Telecom conduit and vault permits for fiber or communications infrastructure
  

Encroachment and Right-of-Way Permits
If utility work crosses or affects public roads, sidewalks, or easements, an encroachment permit or right-of-way (ROW) permit is required. These are reviewed by the city or county’s public works or transportation department.

• Applies to trenching, boring, and utility pole placement in public areas
  
• Ensures public safety and restoration of disturbed infrastructure
  
• May require traffic control plans and liability insurance
  

Supporting Plans, Approvals, and Inspections
Permit approval for utility installation often requires submission of engineered utility plans, coordination with service providers, and multiple inspections during and after construction.

• Utility layout drawings must meet code and provider specifications
  
• Erosion control and trench safety measures are commonly required
  
• Final utility inspections are mandatory before activation or certificate of occupancy
