McAllen, Texas homeowners who plan rooftop or ground-mounted solar must follow city building and electrical permit rules, coordinate with McAllen Public Utilities for interconnection, and meet inspections before operating systems. This guide explains which permits to apply for, who enforces the rules, common violations, and practical steps to get approved and connected.

What permits apply

Most residential photovoltaic (PV) installations require a building permit and an electrical permit; larger installations may need site or zoning review. Confirm permit types with Development Services before purchasing equipment.[2]

Check permit triggers with the city early to avoid delays.

Step-by-step overview

  • Obtain a preliminary plan showing array location, roof attachments, and single-line electrical diagram.
  • Apply for a building permit and electrical permit from Development Services; include manufacturer specs and installer license where required.[2]
  • Schedule required inspections (roof/structural, electrical) with the city after installation.
  • Coordinate interconnection and any net-metering or meter exchange with McAllen Public Utilities; submit MPU interconnection requests as required.[3]
  • Obtain final approval or certificate of occupancy/electrical approval before placing equipment into service.

Penalties & Enforcement

Enforcement of building, electrical, and zoning violations is handled by the City of McAllen Development Services (Building Inspections) and McAllen Public Utilities for electric interconnection issues. The municipal code sets the enforcement framework; specific fines for solar permit violations are not specified on the cited municipal code page and may be set by separate fee schedules or administrative orders.[1]
