Dallas Solar
Permit Design.
Oncor Territory.
Building Permit Required — Unlike Houston.

Dallas solar permit drawings and plan sets for City of Dallas and all Dallas County AHJs. Dallas is in Oncor's ERCOT territory — same deregulated market as Houston, but Dallas requires both a building permit and an electrical permit for residential solar. Your customer also needs a solar buyback REP before the system goes live. Free for first-time clients.

Dallas Solar — Two Things That Differ From Houston

Dallas Is in the Same Oncor ERCOT Market as Fort Worth. But Dallas Requires a Building Permit Alongside the Electrical Permit — and Your Customer Still Needs a Solar Buyback REP.

Installers who work both Houston and Dallas sometimes assume Dallas follows Houston's electrical-only permit process. It doesn't. Dallas Building Inspection requires both a building permit and an electrical permit for residential solar. The other constant is ERCOT: Oncor distributes electricity but doesn't buy solar exports. Your customer needs a solar buyback REP enrolled before the system goes live, or every exported kilowatt-hour earns nothing.

Building + Electrical Permit · Dallas Building Inspection
Dallas requires both permits — plan sets must include structural drawings that Houston's electrical-only format doesn't need.
⚠️Building permit required — not electrical only like Houston
⚠️Structural drawings required: roof layout, racking, load path
Dallas Building Inspection: $300–600 typical fee · online portal
3–5 week plan check typical for residential solar
Submit Oncor interconnection simultaneously — don't wait
Oncor + ERCOT REP · Choose Solar Buyback Before Install
Oncor handles interconnection but doesn't set export rates. A solar buyback REP must be active before the system goes live.
⚠️Oncor interconnection: 4–6 weeks · start with permit submission
⚠️Without solar buyback REP, exports earn $0 in ERCOT market
TXU Solar Buyback: retail-match credits in Oncor territory (2026 top option)
Chariot Energy: top-rated overall 2026
Green Mountain Solar Credit 12: non-expiring rollover credits
⚠️ Some Dallas-area addresses are served by Garland Power & Light or Denton Municipal Electric — not Oncor. These are municipal utilities with completely different interconnection processes. We confirm the distribution utility for every Dallas address before building the plan set.
Why Dallas Installers Outsource

Houston Plan Sets Don't Work in Dallas. Suburban AHJ Fragmentation. Municipal Utility Pockets in a Deregulated Market.

📐
Using a Houston-Format Plan Set in Dallas Gets the Building Permit Rejected
Houston's electrical-only permit doesn't require structural drawings — a single-line diagram and basic site plan is sufficient. Dallas Building Inspection requires a full plan set with structural roof layout, racking detail, and load path documentation. Submitting a Houston-format set to Dallas Building Inspection generates an automatic rejection for missing structural content. We know which format each Texas city requires and build accordingly.
🏙️
The DFW Suburb Problem — 15+ Different Building Departments in Dallas County
A Dallas County address doesn't mean Dallas Building Inspection is the AHJ. Plano, Irving, Garland, Richardson, Mesquite, Grand Prairie, Carrollton, and a dozen other cities each have their own building departments and permit requirements. Assuming the Dallas Building Inspection process applies county-wide is one of the most common mistakes Dallas-area installers make when they're new to the market.
Garland Power & Light and Denton Municipal Electric Are Not Oncor
Garland and Denton have their own municipal electric utilities — not Oncor, not in the ERCOT deregulated REP market. Interconnection processes, net metering terms, and export rates are completely different from Oncor territory. An Oncor interconnection application submitted for a Garland Power & Light address gets rejected. We confirm the distribution utility per address before building.

Dallas Solar Market — 2026

Four Things That Define Solar in Dallas.

Bldg + Elec
Two Permits Required — Not One Like Houston
Dallas requires both a building permit and electrical permit for residential solar — a key difference from Houston's electrical-only process. Plan sets must include structural drawings: roof layout, racking configuration, and attachment load path. Dallas Building Inspection reviews both simultaneously. Submit the Oncor interconnection application on the same day you submit permits — interconnection is the long pole at 4 to 6 weeks.
TXU
TXU Solar Buyback — Retail-Match Credits in Oncor Territory
TXU Solar Buyback 12 and 24 offer retail-match export credits in Oncor territory — the closest thing to traditional 1-to-1 net metering available in the Dallas market. Chariot Energy is the top-rated overall in 2026. Green Mountain Solar Credit 12 offers non-expiring credits that roll forward indefinitely. Help every Dallas customer compare options at PowerToChoose.org before signing the install contract.
NCTCOG
North Central Texas COG — Regional Code Standard for DFW
The North Central Texas Council of Governments coordinates building and electrical code adoption for the DFW metroplex. NEC 2020 is the current working standard. NCTCOG is actively preparing NEC 2026 adoption with regional amendments — Dallas and Fort Worth are likely to transition on a similar timeline. Verify the current code with Dallas Building Inspection for any project submitted after Q3 2026.
Hail Zone
North Texas Hail and Wind — Module and Structural Specs Matter
North Texas sits in one of the most active large-hail corridors in the US. Dallas regularly sees hail events above 1.5 inches. Module selection matters here — IEC 61215 impact resistance and manufacturer hail ratings are meaningful in customer conversations. Structural calcs must account for North Texas ASCE 7 wind values including potential tornado uplift for commercial ground-mount installations in open terrain.

FAQ

Questions Dallas Installers Ask Us

Yes — Dallas requires both a building permit and a separate electrical permit for residential solar installations. This is different from Houston, which requires only an electrical permit for residential systems under 50kW. Plan sets for Dallas must include structural drawings showing roof layout, racking configuration, and load path — not just the electrical single-line diagram. Dallas Building Inspection reviews both permits. Typical plan check: 3 to 5 weeks for residential solar.
Oncor Electric Delivery owns and operates the distribution grid serving Dallas and most of DFW. Oncor is a regulated utility — it delivers power but doesn't sell electricity or set solar export rates. In the ERCOT deregulated market, your customer chooses their own Retail Electric Provider for electricity supply and solar buyback. Oncor handles all interconnection applications for Dallas solar regardless of which REP the customer uses. Oncor interconnection: 4 to 6 weeks.
Dallas is in Oncor's ERCOT territory. TXU Solar Buyback 12/24 offers retail-match export credits in Oncor territory — the closest to traditional 1-to-1 net metering available in Dallas. Chariot Energy is the top-rated overall in 2026. Green Mountain Solar Credit 12 offers non-expiring rollover credits. Customers should compare all available plans at PowerToChoose.org and choose a solar buyback REP before the system goes live — without one, all exports earn $0.
No — Garland has its own municipal electric utility, Garland Power & Light, which is separate from Oncor. Garland P&L is not in the ERCOT deregulated REP market. Solar interconnection in Garland goes through Garland P&L, not Oncor, and the export credit structure is completely different. Denton Municipal Electric is similarly separate. We confirm the distribution utility for every DFW address before building — a Dallas County address could be Oncor, Garland P&L, or Denton Municipal.
Dallas uses NEC 2020 as the working electrical standard, consistent with the NCTCOG regional standard for DFW. NCTCOG is actively preparing NEC 2026 adoption with regional amendments — verify the current code with Dallas Building Inspection for any project submitted after Q3 2026.
All of them — City of Dallas, Dallas County, Plano, Irving, Garland, Richardson, Mesquite, Grand Prairie, Carrollton, Farmers Branch, Rowlett, Frisco, McKinney, Allen, and all DFW cities. Each suburb has its own building department. Garland and Denton addresses route to municipal utilities, not Oncor. We confirm AHJ and utility per address before building.
Most Dallas residential plan sets ship in 24 to 48 hours. Battery permit plans same day. Commercial projects: 3 to 5 business days. Rush available on request.
