Access Control Permit Requirements in San Antonio, Texas

Quick Answer: Access control system installations in San Antonio typically do not require a building permit when operating at 50 volts or less. However, contractors must hold a Texas DPS Private Security Bureau Class D (Electronic Access Control Device Company) or Class B (Security Contractor) license. If the installation involves connections to fire alarm systems or requires structural modifications, additional permits may apply.

When Is a Permit Required?

San Antonio follows a practical approach to low voltage work permitting:

Permit Exemptions (Low Voltage)

Per the San Antonio Code of Ordinances, the following are generally exempt from electrical permits:

• Installation of wiring and equipment operating at 50 volts nominal or less
• Telephone, voice, data, and communication systems
• Cable TV and broadband installations
• Standalone access control systems that don't interface with fire alarm or life safety systems

Important: Even exempt work must comply with NEC Article 250 and Chapter 8 grounding requirements. Exemption from permits does not authorize work that violates code.

When Permits ARE Required

You will need permits for access control projects that include:

• Integration with fire alarm systems (requires fire alarm permit)
• Electric strike or magnetic lock installations that affect fire-rated doors
• Structural modifications (wall penetrations, door frame alterations)
• Power supply installations over 50 volts
• Projects in city facilities or critical infrastructure

Contractor Licensing Requirements

While building permits may not always be required, contractor licensing is mandatory for all access control work in Texas.

Texas DPS Private Security Bureau License

The Texas Department of Public Safety Private Security Bureau regulates access control contractors. You need one of these licenses:

Class D – Electronic Access Control Device Company

Required if your company installs or maintains electronic access control devices. This is the minimum license needed for access control-only work.

Class B – Security Contractor Company

A broader license that includes authorization for:

• Alarm systems
• Electronic access control
• CCTV/surveillance
• Locksmith services
• Guard services

Most low voltage contractors choose the Class B license as it covers multiple service categories.

For comprehensive information on Texas low voltage contractor licensing, see our Texas Low Voltage License Guide.

Company Representative Requirements

Every licensed company must have a designated Company Representative who:

• Has two consecutive years of verifiable full-time work experience in access control
• Passes a written examination (50 questions, 70% to pass)
• Oversees regulatory compliance for the company

Exams are administered in Austin, Houston, and Irving. The test covers Texas Occupations Code Chapter 1702 and Texas Administrative Code Chapter 35.

Individual Installer Requirements

Technicians who install access control devices must:

• Register as an Electronic Access Control Device Installer with DPS
• Pass an examination covering access control subject matter
• Complete 8 hours of continuing education each renewal period (7 hours technical + 1 hour ethics)

Application Process

Residential vs. Commercial Projects

Residential Access Control

• Typically exempt from building permits (under 50V)
• Common systems: smart locks, video doorbells, keypad entry
• Still requires state licensing to install for compensation
• Homeowner self-installation is permitted for their own property

Commercial Access Control

• Usually exempt from building permits if standalone low voltage
• More complex projects often interface with fire alarm and must be permitted
• Must comply with ADA accessibility requirements
• Fire-rated door modifications require careful coordination with fire marshal
• High-security facilities may have additional requirements

Code Compliance Considerations

Fire Door Integration

When installing access control on fire-rated doors, you must ensure:

• Magnetic locks release upon fire alarm activation
• Exit devices comply with egress requirements
• Door closer operation isn't compromised
• Coordination with fire alarm contractor if required

ADA Compliance

Commercial access control must meet accessibility standards:

• Card readers and keypads at proper mounting height (48" max)
• Door opening force within limits
• Automatic door operators when required
• Visual and audible feedback for users with disabilities

NEC Requirements

Even when permits aren't required, follow:

• NEC Article 250 – Grounding requirements
• NEC Chapter 8 – Communication systems
• Proper cable support and routing
• Separation from power conductors

Pro Tips from the Field

Document Everything: Even when permits aren't required, maintain thorough documentation. This protects you if questions arise later and helps with future service calls.

Verify Fire Door Ratings: Before installing any access control on a door, check if it's fire-rated. Modifying fire doors without proper consideration can create liability issues and code violations.

Coordinate with Other Trades: Access control often touches electrical, fire alarm, and even structural work. Communicate with other contractors to avoid conflicts and ensure proper integration.

Stay Current on Licensing: Texas DPS doesn't send renewal reminders. Set your own calendar alerts 60-90 days before expiration to complete continuing education and renew on time.

Get It In Writing: When building management says "no permit needed," get written confirmation. Requirements can vary by property, especially in commercial buildings with strict documentation requirements.
