Electrical Permit in San Antonio, TX
Permit Summary
Who Can Do the Electrical Work?
Homeowner Eligibility Rules
For permit-required electrical work, San Antonio does not provide a general homeowner electrical-permit path. City residential guidance says homeowners must use licensed trade contractors for new electrical project components, and Chapter 10 states that an electrical-work permit may not be issued to a person who does not hold the license required for that class of work. Permit-exempt tasks remain governed by the specific exemptions in Chapter 10.
Contractor Rules
A State of Texas electrical license is required to perform electrical work in San Antonio, and state-licensed electrical contractors must register with Development Services to receive permits. Registration requires government photo identification, the state contractor and master-license ID cards, and proof of liability insurance. The City no longer issues new Electrical Contractor Licenses but honors existing City-issued licenses. Electrical contractors must maintain the required liability insurance; the City's current contractor page states at least $300,000 bodily-injury liability and $300,000 property-damage liability. Limited maintenance work may be performed under an annual electrical maintenance permit by qualified, City-registered electrical maintenance technicians.
Permit & Plan Review
Electrical Work Covered
Permit-required electrical work includes new and existing residential and commercial electrical installations and alterations, service and meter-related work, panels/load centers, switchgear, transformers, circuits and devices, motors, generators/UPS, distributed generation and storage batteries, temporary wiring, controls or low-voltage systems over 50 volts, Temporary Meter Loop (TML) and Temporary on Permanent Set (TOPS) work, and reconnect work, subject to the code's permit exemptions.
Plan Review Rules
The current Electrical Permit Application requires professional-engineer-sealed electrical drawings and plan review when any equipment is over 600 amps at 250 volts or less or over 400 amps at 250 volts or greater, any system is over 600 volts, or the electrical work area is on more than one floor or exceeds 5,000 square feet. The current FY 2027 fee schedule sets the electrical plan-review fee at $115.
Quick / No-Plan Permit Rules
Electrical trade permits can be submitted through the City's online permitting system or obtained at the One Stop. The electrical application distinguishes scopes that require formal plan review; work that does not meet those triggers can use the ordinary trade-permit path without that electrical plan review. When electrical work is part of a building project, the trade permit must be linked to the parent building permit. Reconnect permits are an exception to the online-only convenience: the City directs applicants to apply for a reconnect permit in person at the One Stop.
Service, Panel & Utility Requirements
Service / Panel Rules
The Electrical Permit Application itemizes service ratings, additional meters, panelboards/load centers, switchgear, transformers, and whether work with CPS Energy is required. Permit fees for commercial and existing-residential work include the $57.50 electrical base fee plus applicable service-rating and equipment charges. A Temporary Meter Loop permit authorizes an electrical panel and temporary meter for construction power. New or changed service and meter work that involves CPS Energy also requires utility coordination and the applicable City inspections.
Service Reconnect Rules
To re-establish utility service, the City may require an electrical safety inspection. The property owner must apply for a reconnect permit in person at the One Stop; after the required inspection is approved, Development Services notifies CPS Energy that the property is safe for utility service. The FY 2027 fee schedule lists a $57.50 reconnect permit base fee, with separate temporary-reconnect fees when applicable.
Low-Voltage Rules
A permit is not required for the portion of wiring and equipment used for telephone, voice, data, cable TV, broadband, and other communications systems that operates at 50 volts nominal or less, provided the system is grounded as required by the NEC. The electrical fee schedule separately lists controls/low-voltage systems over 50 volts as permit-fee items.
Utility Coordination Rules
Coordinate with CPS Energy when the project changes or establishes electric service, meters, temporary construction power, or other work identified as 'Work With CPS.' After final approval of required City inspections, Development Services notifies CPS Energy that the property is safe to energize. Registered electrical contractors may use TML for temporary construction power or TOPS for temporary service before all final inspections; those permits should be linked to the main building permit.
Inspections & Permit Life
Electrical Inspection Stages
Inspection stages depend on the electrical scope. Development Services' electrical inspection program includes project-specific inspections such as concrete-encased electrode, conduit in trench, foundation/slab, rough-in, Work With CPS, TML, TOPS, and final inspections. Chapter 10 requires permitted work to remain accessible and exposed until approved. Inspection requests placed before midnight are scheduled for the next day.
Permit Expiration / Inspection Interval
A permit application is deemed abandoned after 180 days unless it has been pursued in good faith or a permit has been issued; the Building Official may grant written application extensions of up to 90 days each for justifiable cause. An issued permit becomes invalid if authorized work does not commence within 180 days after issuance or if work is suspended or abandoned for 180 days after it begins. The Building Official may grant one or more written permit extensions of up to 180 days each for justifiable cause.
What You Need Before Applying
Requirements
For permit-required electrical work, obtain the Electrical Permit through Development Services before work begins, except for the code's emergency-repair procedure. Electrical permits must be pulled by a properly licensed person or contractor; state-licensed electrical contractors must register with the City. Link trade permits to the parent building permit when the electrical work is part of a permitted building project. Projects that meet the City's electrical plan-review triggers require professional-engineer-sealed electrical drawings and plan review. Permitted work is subject to inspection and must comply with the City's adopted electrical and building-related codes.
Exemptions
Chapter 10 exempts specified electrical work from a permit, including minor repairs or maintenance performed by a licensed electrical contractor; lamp replacement; connecting approved portable equipment to approved permanent receptacles; qualifying refrigeration/HVAC motor, solenoid-valve, or associated-control replacement by a licensed mechanical contractor; telephone, voice, data, cable TV, broadband, and other communications wiring and equipment operating at 50 volts nominal or less; specified City utility work; radio/TV transmission equipment other than its power supply and towers or antennas; and temporary systems used to test or service electrical equipment. Emergency repairs are not a general exemption: the permit application must be submitted by the next business day.
Required Documents
The Electrical Permit Application or BuildSA record requires the project address, property owner, registration holder, contractor/company and state-license information, contact information, occupancy and permit type, work type and work summary, related building-permit number when applicable, service/equipment details, and whether work with CPS Energy is required. Professional-engineer-sealed electrical drawings are required when the project meets an electrical plan-review trigger.
