Solar Panel Permit Requirements in Texas (2025)

Do You Need a Permit for Solar Panels in Texas?

Most Texas homeowners need at least two permits: a building permit for structural load and roof attachment, and an electrical permit for wiring, the inverter, and meter connections. Both are issued by your local city or county building department, not a state agency. Texas has no statewide solar permit form or unified fee schedule.

In addition to local permits, you must obtain utility interconnection approval from your Transmission and Distribution Utility (TDU) before your system can legally be energized. The permitting and interconnection processes run in parallel, and both must be complete before operation.

Key points:

• HOA restrictions are limited. Texas Property Code § 202.010 prohibits homeowners associations from banning solar panels. They can regulate placement and aesthetics within limits but cannot deny installation.
• Your contractor pulls the permit. A licensed electrical contractor usually pulls the permit. Some jurisdictions allow homeowners to pull their own permits under owner-builder rules, but all inspections must still be passed.
• The timeline is 4 to 12 weeks. Plan for 4 to 12 weeks from permit application to energization, depending on your jurisdiction, utility, and system size.

The interconnection framework for distributed generation customers is governed by Texas Utilities Code § 39.916. HOA solar access rights fall under Texas Property Code § 202.010.

State vs. Local Permit Authority in Texas

Texas delegates building and electrical permitting authority to local governments. No state agency issues residential solar permits, and no standardized fee schedule applies statewide. The rules in Austin differ from those in Houston or an unincorporated area of Parker County.

Incorporated Cities

If you live inside city limits, your city's building department issues both the building and electrical permits. Cities set their own fee schedules, review timelines, and inspection requirements. Cities with municipally owned utilities, such as Austin (Austin Energy) and San Antonio (CPS Energy), may add solar program review steps on top of standard building department permits.

Unincorporated County Areas

Some Texas counties do not require building permits for residential construction. However, counties with extraterritorial jurisdiction (ETJ) zones adjacent to cities may apply city rules or have their own requirements. If you are in an unincorporated area, contact your county development office to confirm permit requirements. Even if no local building permit is needed, the utility interconnection application is still mandatory.

What the State Does Control

The Public Utility Commission of Texas (PUCT) has rulemaking authority over interconnection standards for distributed generation under Texas Utilities Code Chapter 39. PUCT Substantive Rule 25.211 governs the interconnection of on-site distributed generation and sets baseline requirements that TDUs must follow. Local permits are outside PUCT's scope, but interconnection is not.

HB 3905 (89R), relating to the interconnection of distributed generation, was referred to the House State Affairs Committee in March 2025. If enacted, it could alter the interconnection process. As of publication, it has not passed. Consult the Texas Legislature Online for current status.

Building Permit vs. Electrical Permit: The Difference

Some cities issue these as a combined solar permit. Others require separate applications and inspections.

Permit Types, Fees, and Timelines by Major Texas Jurisdiction

The table below reflects general information. Fee schedules change. Verify current numbers directly with the relevant department before signing a contract.

The City of Houston generally does not require a building permit for this work, but an electrical permit from the Bureau of Permits is required. Confirm the current solar-specific rule with the Houston Bureau of Permits, as interpretations can shift.

How Fees Are Calculated

Texas jurisdictions use two common methods:

• Per-watt basis: A flat rate multiplied by the system's rated output in watts.
• Per-project-value basis: A percentage of the declared project value or a tiered fee table based on construction valuation.

Ask your building department which method applies and request the current fee schedule.

Inspection Checkpoints

Most Texas cities require at minimum:

• Rough-in electrical inspection (before conduit and wiring are covered)
• Final electrical inspection
• Final building inspection (racking and roof penetrations)
• Some utilities require a witness inspection or meter upgrade inspection before issuing Permission to Operate.

Expedited Review and Permit Validity

Several Texas cities offer over-the-counter or same-day permit approval for smaller residential systems, typically those under 10 kW. Ask about expedited review when you submit. Permits are typically valid for 180 days from issuance, meaning work must begin within that window. Confirm the validity period with your local department.

Contractor Licensing Requirements for Solar Installers in Texas

Electrical Licensing Under TDLR

All electrical work on a solar installation must be performed by a licensed electrician or electrical contractor under Texas Occupations Code Chapter 1305. The Texas Department of Licensing and Regulation (TDLR) administers the electricians licensing program under 16 TAC Chapter 73.

In most jurisdictions, a Master Electrician license is required to pull an electrical permit. A Journeyman Electrician can perform the work under a Master Electrician's supervision, but the Master Electrician is the responsible party.

Verify any electrician's license at the TDLR license lookup tool: tdlr.texas.gov.

New in 2025: Residential Solar Retailer Registration (SB 1036)

SB 1036 (89R), the Residential Solar Retailer Regulatory Act, creates a new occupational registration for companies that sell residential solar systems. This registration is administered by TDLR and is separate from the electrical contractor license. The bill authorizes fees and penalties for unregistered solar retailers.

As of publication, SB 1036's effective date and TDLR's rules for the program have not been confirmed. The bill's latest action date was June 25, 2025. Verify the current status and whether TDLR has published rules before assuming the registration is in effect.

Once rules are promulgated, you should ask any solar sales company for their TDLR Residential Solar Retailer registration number before signing a contract. Until then, verify at minimum that the company's electrician holds a valid TDLR Master Electrician license.

Owner-Builder Exemption

Texas law allows homeowners to pull their own permits in some jurisdictions without a contractor license. However, you must still pass all required inspections, and some cities restrict owner-builder permits for electrical work. If you plan to self-install, confirm with your local building department whether the owner-builder exemption applies to solar electrical work.

Interconnection and Net Metering: Utility Approval Process

The Two-Track Process

Getting your system energized requires completing two separate processes:

1. Local building permit and inspections (city or county)
2. Utility interconnection application (your TDU)

Both must be complete before your system can legally operate. Start the interconnection application at the same time you submit your permit application.

Who to Apply To in Deregulated ERCOT Areas

In the ERCOT deregulated market, you submit your interconnection application to your TDU, not your retail electric provider (REP). Your REP sells you electricity; your TDU owns the wires. The major residential TDUs are:

• Oncor Electric Delivery (Dallas-Fort Worth area)
• CenterPoint Energy (Houston area)
• AEP Texas (West and South Texas)
• Texas-New Mexico Power (TNMP) (portions of North and West Texas)

El Paso Electric operates outside ERCOT and handles its own interconnection process.

What You Need to Submit

Standard interconnection application documents include:

• Single-line electrical diagram
• Equipment specification sheets (inverter, panels, racking)
• Copy of your local building permit (some TDUs require permit approval before they will approve interconnection)

Consult your TDU's distributed generation interconnection application requirements.

Interconnection Timeline

For residential systems at or under 10 kW, TDU interconnection review typically runs 10 to 30 business days after a complete application is submitted. Incomplete applications restart the clock. Confirm current timelines directly with your TDU.

Net Metering and Buyback Rates

Texas does not mandate net metering statewide. Credit rates for excess solar generation vary by utility:

• Austin Energy uses a Value of Solar (VOS) tariff, which sets a per-kWh credit rate. Consult Austin Energy for the current VOS rate.
• CPS Energy and other utilities offer avoided-cost buyback rates, which are typically lower than the retail rate.
• In deregulated areas, your REP may offer a buyback plan, but rates and terms vary. Confirm your REP's buyback rate before finalizing your system design.

HB 3905 (89R) proposes changes to distributed generation interconnection rules. As of March 2025, it was referred to the House State Affairs Committee and had not passed. Verify its final status before relying on any changes it would make to PUCT Substantive Rule 25.211 or Texas Utilities Code § 39.916.

What Changed Recently: 2024–2025 Texas Solar Legislation

The 89th Texas Legislature (2025 session) produced several bills affecting residential solar. Bills in committee are not law. Verify final status at capitol.texas.gov or openstates.org before acting on any of these.

SB 1036 (89R) — Residential Solar Retailer Regulatory Act

Creates a new TDLR registration for companies selling residential solar. Authorizes fees and penalties for unregistered retailers. Latest action was recorded June 25, 2025. For the effective date and TDLR rulemaking timeline, consult TDLR at tdlr.texas.gov. Once rules are final, homeowners should verify contractor registration status before signing a contract.

HB 3905 (89R) — Distributed Generation Interconnection Reform

Would modify interconnection rules for distributed generation customers under PUCT authority. Referred to House State Affairs as of March 28, 2025. Not yet law.

HB 4363 (89R) — Battery Energy Storage Facilities

Addresses permitting and fees for battery energy storage facilities. Relevant if you are adding battery storage. Referred to House State Affairs as of April 2, 2025. Not yet law.

HJR 157 (89R) — Proposed Constitutional Amendment for On-Site Generation Property Tax Exemption

Would authorize the legislature to exempt from property tax the appraised value increase from an on-site generation system. Referred to House Ways and Means as of March 24, 2025. A constitutional amendment requires legislative passage and voter approval. It has not cleared committee.

Existing Property Tax Exemption: Texas Tax Code § 11.27

Texas already exempts the added home value from a solar or wind energy device from property tax appraisal under Texas Tax Code § 11.27. This exemption applies to rooftop residential solar and is currently in effect. The protections of § 11.27 do not depend on HJR 157 passing.

SB 1478 (89R) — Solar Facilities on Leased Property

Addresses removal of solar and wind facilities on leased property. Referred to Senate Business and Commerce as of March 6, 2025. Relevant for solar leases. Not yet law.

Next Steps and Who to Contact in Texas

Step 1: Contact your local city or county building department to confirm current permit requirements and fee schedules before you sign a contract.

Step 2: Verify your solar installer holds a valid TDLR Master Electrician license at tdlr.texas.gov. Once SB 1036 rules are final, also verify the company's Residential Solar Retailer registration.

Step 3: Submit your TDU interconnection application as early as possible. Ask your TDU what they need to start their review.

Step 4: Confirm your REP's solar buyback or net metering rate in writing before your system design is finalized.

Step 5: After passing final inspection, obtain your Permission to Operate (PTO) letter from your TDU before energizing the system. Operating without PTO can result in disconnection and may void your interconnection agreement.

Key Contacts

HOA Disputes

If your HOA attempts to block your solar installation, Texas Property Code § 202.010 limits that authority. HOAs cannot prohibit solar panels, though they may regulate placement. If your HOA is unresponsive to the statute, file a complaint with the Texas Attorney General's Consumer Protection Division.
