Electricians in McKinney

Texas law makes TDLR adopt each new edition of the National Electrical Code, published every three years. The 2026 NEC took effect statewide on September 1, 2026, with a limited exception to the GFCI rule for certain outdoor outlets; the 2023 edition applied before that. Cities may require inspections and adopt local amendments, and work inside city limits must follow local ordinances. Ask the electrician which code edition their quote assumes, whether the City of McKinney has local amendments that touch the job, and for the permit number.

A city may not charge a state-licensed electrician a registration fee, but it can still collect building permit fees, and it may not make a state licensee sit a local exam.

HomeGuide's February 2026 national figures: $50 to $130 an hour, a $100 to $200 service call covering the first hour, $150 to $600 for small jobs and $2,000 to $10,000 or more for large projects. Replacing a panel with a 200-amp panel runs $1,400 to $2,800 including labor. If you are adding an AC condenser or EV charger, ask whether the quote includes panel work.

• Search TDLR's License Data Search for both the person and the electrical contractor. Licenses renew every year.
• Look at the truck. Contractors must show the business name and TDLR license number on both sides of every vehicle, in letters at least two inches high.
• Ask for insurance. Electrical contractors must carry liability cover of at least $300,000 per occurrence and $600,000 aggregate, and either carry workers' compensation or file a notice of no coverage with TDI.
• Know the levels. A contractor must be, or employ, a Master Electrician. A journeyman has at least 8,000 hours of training; a master at least 12,000 hours plus two years as a journeyman.

Texas licensing law doesn't cover an owner's work on the home they live in where a city ordinance doesn't specifically regulate it, so check the city's permit rules before you start. Attaching an appliance power cord, though, takes a TDLR Residential Appliance Installer license unless it was installed at the factory. TDLR takes complaints through its online process.

Oncor lists McKinney among the cities it serves; check your bill to confirm your address. In Oncor areas the customer is responsible for trees along the service line from the pole to the house; Oncor says to request a temporary disconnect, which carries a charge, before that work.
