Permit Design.
Same Oncor as Dallas.
Different AHJ. Confirm Before You Build.
Fort Worth solar permit drawings and plan sets for City of Fort Worth and all Tarrant County AHJs. Fort Worth is in the same Oncor ERCOT territory as Dallas — but Tarrant County has over 20 separate building departments. A Fort Worth mailing address could route to half a dozen different AHJs. We confirm before we draw a line. Free for first-time clients.

The Fort Worth AHJ Problem
A Fort Worth Mailing Address Is Not the Same as Fort Worth Building Department Jurisdiction. Tarrant County Has Over 20 Separate Building Authorities.
Fort Worth is the fifth-largest city in Texas — but a large portion of what people call "Fort Worth" is actually inside smaller incorporated cities and unincorporated Tarrant County, each with its own building department, permit process, and fee schedule. The Oncor utility is consistent across all of them. The AHJ is not. We confirm the jurisdiction for every Fort Worth area address before building the plan set.
City of Fort Worth Development Services — Incorporated FTW Addresses Only
City of Fort Worth Development Services handles permits for addresses within Fort Worth city limits. Building + electrical permit required. Plan sets need structural drawings, not just electrical.
✅Fort Worth Development Services ePlans portal
✅$300–650 typical residential solar fee
✅3–5 week plan check for standard residential
⚠️Fort Worth mailing address ≠ Fort Worth AHJ automatically
Tarrant County + Suburban Cities — Everything Outside Fort Worth City Limits
Arlington, Mansfield, Hurst, Euless, Bedford, North Richland Hills, Colleyville, Grapevine, Southlake, Keller, and Tarrant County unincorporated each have their own building departments.
⚠️Each suburb = separate building dept, portal, fee schedule
⚠️Tarrant County handles unincorporated addresses outside city limits
✅All serve Oncor for distribution — same interconnection process
✅All use NEC 2020 under NCTCOG regional standard
⚠️ A Fort Worth mailing address does not determine the AHJ. An address can have a Fort Worth ZIP code and mailing address but fall inside Keller, Saginaw, Watauga, or unincorporated Tarrant County — each a different building department with different permit requirements and timelines. We pull the jurisdiction map for every Fort Worth area address before building.
Why Fort Worth Installers Outsource
Wrong AHJ on the Cover Sheet. Dallas-Format Plan Sets for Fort Worth Suburbs. REP Not Selected Before Install.
Submitting a Plan Set to the Wrong Building Department Wastes Weeks
Installers unfamiliar with Tarrant County sometimes submit Fort Worth Development Services applications for addresses that are actually in Keller, Saginaw, or unincorporated county. The application gets rejected — not reviewed, not flagged, just rejected — because the AHJ has no jurisdiction over that address. Resubmitting to the correct jurisdiction restarts the clock. We confirm jurisdiction before we draw the first line.
Oncor Territory Is Consistent — But the REP Selection Requirement Is Often Skipped
All Tarrant County solar connects through Oncor — the same as Dallas. Oncor handles interconnection but doesn’t set solar export rates. Customers need a solar buyback REP active before the system goes live. Fort Worth installers who don’t walk customers through REP selection leave them exporting for $0 until they realize the error and switch plans. TXU Solar Buyback, Chariot Energy, and Green Mountain Solar Credit 12 are the leading options.
Fort Worth Suburban Permit Timelines Vary Widely — Some Suburbs Are Faster Than Fort Worth Proper
City of Fort Worth plan check for residential solar runs 3 to 5 weeks. Several Tarrant County suburbs — including Colleyville, Southlake, and Keller — have faster residential review, sometimes as short as 10 business days. Knowing which suburb is the AHJ isn’t just about avoiding rejection — it can mean a faster project timeline than if the application goes to Fort Worth proper by default.

Four Things That Define Solar in Fort Worth.
20+ AHJs
Tarrant County Jurisdiction Fragmentation — AHJ Confirmation Is Non-Negotiable
Fort Worth proper, Arlington, Mansfield, Hurst, Euless, Bedford, North Richland Hills, Colleyville, Grapevine, Southlake, Keller, Saginaw, Watauga, and Tarrant County unincorporated all have separate building authorities. Every address needs an AHJ lookup before the plan set format is determined. We do this on every Fort Worth project — not after the plan set is rejected, before.
Oncor
Same Distribution Utility as Dallas — Consistent Interconnection Across All Tarrant County
Oncor serves all of Tarrant County for electricity distribution. Interconnection applications go to Oncor regardless of which Tarrant County city is the AHJ. ERCOT REP solar buyback applies across all of Oncor territory. TXU Solar Buyback retail-match, Chariot Energy, and Green Mountain Solar Credit 12 are the leading solar buyback plans. Every customer needs a solar buyback REP enrolled before the system goes live.
Hail Zone
North Texas Hail Corridor — Module Specs Matter for Fort Worth Customers
Fort Worth sits in one of the most active large-hail zones in the US — the same corridor as Dallas. Annual hail events above 1 inch are common; events above 2 inches happen multiple times per decade. IEC 61215 module impact ratings and manufacturer hail certifications are meaningful here. Structural calcs also account for higher wind speeds, particularly in open terrain areas west of Fort Worth.
Suburbs
Southlake, Colleyville, Keller — High-Value Suburbs with Strong Solar + Battery Demand
Fort Worth’s northeast suburbs — Southlake, Colleyville, Keller — are among the highest-income markets in Texas. Large lots, high utility bills, and strong environmental motivation drive solar and battery attachment. Southlake and Colleyville regularly permit residential solar in under 2 weeks.

FAQ
Questions Fort Worth Installers Ask Us
More than 20 — each incorporated Tarrant County city has its own building department; Tarrant County Building Division handles unincorporated addresses. City of Fort Worth is the largest, but Arlington, Mansfield, Hurst, Euless, Bedford, North Richland Hills, Colleyville, Grapevine, Southlake, Keller, Saginaw, and Watauga all have separate building authorities. A Fort Worth mailing address or ZIP code does not determine the AHJ. We look up the jurisdiction for every address before building the plan set.
Yes — all of Tarrant County is in Oncor Electric Delivery territory. Oncor handles all solar interconnection applications regardless of which city is the AHJ. The ERCOT deregulated market applies across all of Tarrant County: customers choose their Retail Electric Provider for solar buyback. Oncor interconnection typically takes 4 to 6 weeks. Submit the Oncor application simultaneously with the building permit to avoid adding weeks to the project timeline.
Fort Worth is in Oncor’s ERCOT territory — same REP market as Dallas. TXU Solar Buyback offers retail-match export credits in Oncor territory in 2026. Chariot Energy is the top-rated overall. Green Mountain Solar Credit 12 offers non-expiring rollover credits. Compare all plans at PowerToChoose.org. REP enrollment must be active before the system goes live — without a solar buyback plan, all exports earn $0.
City of Fort Worth requires both a building permit and an electrical permit for residential solar — same structure as Dallas, not Houston’s electrical-only process. Plan sets must include structural drawings: roof layout, racking detail, and load calculations. Fort Worth suburbs follow the same building + electrical structure under their own building departments.
Fort Worth uses NEC 2020 under the NCTCOG regional standard, consistent with Dallas and the DFW metroplex. NEC 2026 adoption with NCTCOG amendments is being prepared — verify the current code with Fort Worth Development Services for any project submitted after Q3 2026.
All of them — City of Fort Worth, Tarrant County, Arlington, Mansfield, Southlake, Colleyville, Keller, Hurst, Euless, Bedford, North Richland Hills, Grapevine, Saginaw, Watauga, Benbrook, Crowley, and Burleson. Also Weatherford in Parker County, which borders Tarrant to the west. We confirm the AHJ per address for every project.
Most Fort Worth 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.
