City of Dallas Solar Permit Guide
In the City of Dallas you pull building permits before installing rooftop solar, then separately request interconnection from Oncor. Here’s the city side of it.

Permits you’ll need
A building permit and an electrical permit for a flush-mounted or tilt-up PV system. (Solar water heaters also require mechanical and plumbing permits.)
How to submit
Apply through DallasNow, the City of Dallas online permitting portal — or in person at the Oak Cliff Municipal Center, 320 E. Jefferson Blvd., Room 118 — (214) 948-4480. Dallas also requires you to register as a building contractor to pull the permit, and plan sheets must meet the city’s size/legibility standards (minimum 11"×17").
Fees & timeline
Permit fees scale with the system’s valuation; confirm current amounts with Development Services when you apply.
Worth knowing
Notable difference from Houston: Dallas requires your solar construction plans to be reviewed and sealed by a licensed professional engineer (per the Dallas Residential/Building Code). Budget for that PE stamp.
Outside city limits
In unincorporated Dallas County — or another metro city like Garland, Irving, Mesquite, or Plano — you permit through that jurisdiction instead; each sets its own process.
