There is no statewide solar permit in Texas. Every city sets its own submittal requirements, review process, fees, and inspection standards, which means a company installing across DFW, Houston, and San Antonio is really running dozens of different permitting processes at once. This guide covers what's consistent statewide — the legal deadlines, the code baseline, who's allowed to do the work — and how to manage what isn't.
Who actually issues solar permits in Texas
The authority having jurisdiction (AHJ) is almost always the city where the home sits. Cities run their own building departments, their own portals, and their own plan review. Outside city limits, most Texas counties don't require building permits for residential work at all — but that doesn't mean nothing applies. State law still sets the electrical code for unpermitted areas, and the utility still requires a compliant installation before it will interconnect you (more on that in our interconnection guide).
The practical consequence: your submittal package is not one package. Dallas wants structural analysis that Houston may not ask for. One city takes uploads through its portal; the next still wants email. Requirements also change without much announcement, which is why the teams that scale keep a living requirements database per AHJ instead of relying on what worked last quarter.
What state law does standardize
Three things are consistent everywhere in Texas:
The permit clock. Texas Local Government Code §214.904 requires a municipality to grant or deny a building permit application within 45 days. Recent legislation strengthened the consequences — including a third-party plan review path when cities miss deadlines. The details matter enough that we wrote a separate breakdown: The 45-Day Rule.
The electrical code floor. The Texas Department of Licensing and Regulation (TDLR) adopted the 2023 National Electrical Code as the state's minimum standard, effective September 1, 2023. Cities can amend it and adopt on their own schedules, so the working edition varies by metro — several large Texas cities were still reviewing to earlier editions well after the state adoption. Where no permit is required (most unincorporated areas), the state-adopted code is what applies on the day work begins.
Who can do the work. Texas has no solar-specific contractor license. The electrical work runs under TDLR's electrician program: a licensed electrical contractor (TECL) with a master electrician of record, and licensed electricians on the crew. Separately, as of the 2025 legislative session, residential solar retailers and salespeople must register with TDLR — enforcement begins September 1, 2026.

The process, end to end
- Site survey and design. Capture the main panel, service size, roof structure, and meter location accurately the first time — bad survey data is the number-one upstream cause of permit rejections.
- Plan set. Site plan, one-line diagram, equipment spec sheets, structural detail where required, placards and labeling per code. Match the plan set to this AHJ's checklist, not a generic one.
- Submittal. Through the AHJ's portal, counter, or email. Log the submittal date — the statutory clock starts here.
- Plan review. The AHJ approves, or issues comments. Every comment cycle typically costs one to three weeks of calendar time, which is why first-pass approval is the single highest-leverage metric in a permitting operation.
- Permit issuance and installation.
- Inspection. Usually a single final for residential PV; some AHJs want a rough-in or a separate electrical inspection. Our inspection checklist covers the items Texas inspectors flag most.
- Utility interconnection. A separate process with the utility — the permit and the interconnection application run in parallel but have independent clocks. The job isn't done until Permission to Operate.
Where projects actually lose time
Not usually in the AHJ's queue. The quiet killers are handoffs: a plan set waiting three days for internal review, a correction notice sitting unread in a portal inbox, an approved permit nobody scheduled an inspection against. Cities measure their review time; almost nobody measures their own response time to corrections. Teams handle this with tight process — daily portal sweeps, owner-per-stage accountability — or with software built for it. TexPTO exists because spreadsheets stop working somewhere around the third city and the thirtieth open permit: it tracks every job's stage, deadline, and requirement set per AHJ so nothing sits.
FAQ
Do I need a permit for solar in Texas? Inside city limits, almost always — commonly an electrical permit, often a building permit too, depending on the city. Outside city limits, usually no permit, but state electrical code and utility requirements still apply.
How much do solar permits cost in Texas? Commonly a few hundred dollars for residential systems, varying by city and system scope.
How long does solar permitting take in Texas? State law caps municipal review at 45 days; many cities are much faster. Your total timeline depends more on first-pass approval than on the city's speed.
Is Texas a good state for solar permitting? Compared to heavily regulated states, yes — no state-level solar permit, a statutory review deadline, and no permits at all in most unincorporated areas. The difficulty is fragmentation, not strictness.
