Low-Voltage Electrical Permits for Commercial Remodels in Los Angeles

Do you need an electrical permit for low-voltage wiring during a commercial remodel in Los Angeles? In many cases, yes—but the requirement depends on the type of low-voltage circuit, its voltage and power characteristics, and the specific work being performed.
The Los Angeles Department of Building and Safety (LADBS) states that an electrical permit is required for electrical work and provides specific requirements for certain low-voltage installations. LADBS also identifies fire alarm systems as complicated electrical systems that generally require electrical plan check, subject to specific exceptions.
For commercial property owners, general contractors, developers, property managers, and business owners, understanding the permitting requirements before starting a remodel can help prevent construction delays, inspection problems, and unexpected rework.
Cyber Shield Security works with customers on fire alarm and security projects throughout Los Angeles and surrounding communities.

Quick Answer: Do Low-Voltage Systems Need an Electrical Permit in Los Angeles?
Some low-voltage installations require an electrical permit, while others may be exempt depending on the specific system and installation.
LADBS states that a permit may be required when low-voltage work involves certain communication or Class 2 signaling circuits over 30 volts, circuits under 30 volts exceeding 100 VA, certain amplifier circuits, or circuits operating over 15 volts that control, generate, transmit, transform, or utilize more than 25 watts or VA.
The important point is that “low voltage” does not automatically mean “no permit required.”
The exact requirements should be determined based on the equipment, circuit, scope of work, and applicable Los Angeles requirements.
What Is a Low-Voltage Electrical System?
Low-voltage systems generally use electrical circuits that operate at lower voltage than typical building power systems.
Commercial buildings can contain many different low-voltage systems, including:
Fire alarm systems
Security alarm systems
Access control
CCTV and video surveillance
Data and communication systems
Intercom systems
Audio systems
Public address systems
Building automation controls
Certain signaling systems
However, these systems are not all treated identically for permitting purposes.
The type of equipment, circuit characteristics, installation method, and applicable code requirements determine whether a permit or plan review is necessary.
Why Permits Matter During a Commercial Remodel
A commercial remodel can involve multiple trades working simultaneously.
For example, a project may include:
New walls
New ceilings
Electrical upgrades
Lighting
HVAC modifications
Network cabling
Security cameras
Access control
Fire alarm modifications
Emergency systems
LADBS states that a permit is required for private-property construction, alteration, or repair work on buildings within the City of Los Angeles.
This means low-voltage work should not simply be added to a remodel schedule without first determining whether the particular installation requires permitting or plan review.
Fire Alarm Systems Are Different From Ordinary Low-Voltage Cabling
This is one of the most important points for commercial property owners.
A fire alarm system may use relatively low-voltage wiring, but that does not mean it should
automatically be treated like ordinary communication or data cabling.
LADBS specifically identifies Fire Alarm systems as complicated electrical systems that generally require Electrical Plan Check. The City lists certain exceptions, including additions of strobe power supplies and attached devices connected to an existing fire control unit, certain central-station monitoring systems and dialers, and additions of fire-warning devices connected to an existing programmable fire-warning system.
Therefore, a contractor should evaluate the actual fire alarm scope before assuming that the work qualifies for an exemption.
When Is a Low-Voltage Permit Required?
Communication and Class 2 Signaling Circuits
LADBS's published guidance states that a permit is required for certain communication circuits or Class 2 signaling circuits, including circuits over 30 volts or circuits under 30 volts but exceeding 100 VA.
The actual circuit characteristics matter.
Higher-Power Low-Voltage Circuits
LADBS also identifies certain circuits operating over 15 volts that control, generate, transmit, transform, or utilize more than 25 watts or VA as requiring a permit.
This is why simply calling a system “low voltage” is not enough to determine whether a permit is necessary.
Fire Alarm Systems
Fire alarm systems receive additional scrutiny because they are life-safety systems.
LADBS generally classifies fire alarm installations as complicated electrical systems requiring electrical plan check, subject to specified exceptions.
Do Security Cameras Need a Permit in Los Angeles?
The answer depends on the specific installation.
A basic camera installation may involve different requirements from a fire alarm system. However, commercial remodels can introduce additional electrical work, power supplies, raceways, or other components that may change the permitting requirements.
Property owners should have the actual scope evaluated rather than assuming that all CCTV installations are either permitted or exempt.
For a commercial project, the question should be:
What exactly is being installed, how is it powered, and what electrical work is being performed?
Do Access Control Systems Need a Permit?
Access control systems can involve:
Door hardware
Card readers
Keypads
Electric locks
Power supplies
Request-to-exit devices
Control panels
Low-voltage wiring
Whether a permit is required depends on the particular installation and applicable requirements.
If the installation involves electrical work beyond a simple low-voltage signaling circuit, the permitting analysis may be different.
When access control is being installed as part of a larger commercial remodel, it is better to determine the permit requirements before the walls and ceilings are closed.
Does a Fire Alarm Modification Require a Permit?
It can.
A modification to an existing fire alarm system should be evaluated based on the scope of work.
Examples include:
Adding smoke detectors
Adding horn/strobes
Relocating devices
Adding a notification appliance
Adding sprinkler monitoring
Replacing a fire alarm panel
Expanding an existing system
Modifying circuits
Adding power supplies
Some limited fire-warning modifications may fall under exceptions identified by LADBS, while other projects require electrical plan check and permitting.
The safest approach is to determine the exact scope before starting work.
Do Commercial Remodels Require Fire Alarm Plan Review?
Some commercial remodels require fire/life-safety review.
LAFD states that its Fire Life Safety Plan Review team reviews new construction, changes of use, and remodeling projects involving buildings and structures containing applicable State Fire Marshal occupancies. Fire/life-safety systems such as fire alarm systems are included in the review process.
LAFD Fire Development Services is responsible for plan reviews, permit approvals, and field inspections related to fire and life-safety requirements for applicable projects.
This is particularly important for commercial remodels involving:
Multifamily buildings
Hospitals and healthcare facilities
Educational facilities
High-rise buildings
Public assembly occupancies
Certain institutional occupancies
Other regulated commercial occupancies
LADBS vs. LAFD: What Is the Difference?
Property owners often become confused because more than one City department may be involved.
LADBS
The Los Angeles Department of Building and Safety handles building and electrical permitting, plan review, inspections, and related construction services.
LADBS states that electrical permits are required for electrical work and provides specific plan-check requirements for complicated electrical systems, including fire alarm systems.
LAFD
The Los Angeles Fire Department handles applicable fire and life-safety plan reviews and inspections.
LAFD's Fire Life Safety Plan Review covers fire/life-safety systems, including fire alarm systems.
For applicable projects, the two agencies may therefore have different but related responsibilities.
How Does the Permit Process Work for a Commercial Remodel?
The exact process depends on the project, but a typical project can follow these steps.
Step 1: Define the Scope
Determine exactly what will be installed or modified.
For example:
New fire alarm system
Fire alarm expansion
CCTV installation
Access control
Data cabling
Security alarm
Intercom
Other low-voltage systems
Step 2: Determine the Jurisdiction
Confirm that the property is actually within the City of Los Angeles.
This is particularly important for properties in areas such as:
Burbank
Pasadena
Arcadia
Santa Monica
Beverly Hills
West Hollywood
These jurisdictions may have their own building and fire authorities.
Step 3: Determine Permit Requirements
Evaluate the actual electrical characteristics and scope.
Do not rely solely on the phrase “low voltage.”
Step 4: Prepare Plans
If plan review is required, prepare drawings and supporting documentation that accurately describe the proposed installation.
Step 5: Submit Through the Appropriate Process
LADBS provides ePlanLA, its electronic plan-review system, for submitting plans and construction documents electronically.
LAFD also provides its FIMS customer portal for submitting permit applications, uploading plans, tracking permit applications, and requesting inspections.
Step 6: Address Corrections
If the reviewing agency identifies deficiencies, corrections must be addressed before the project can proceed to the applicable approval stage.
Step 7: Obtain the Required Permit
Once applicable plan reviews and clearances are completed, the appropriate permit can be issued.
Step 8: Perform the Installation
The installation should follow the approved scope and applicable requirements.
Step 9: Schedule Required Inspections
Applicable projects may require inspections by the appropriate authority.
Can You Start Low-Voltage Work Before Getting a Permit?
Do not assume that you can.
The answer depends on the specific work and whether a permit is required.
For fire alarm work requiring electrical plan approval, LADBS documentation states that electrical permits for fire alarm system conduits are not issued until the fire warning system plans are submitted and checked, and that work should not be performed on the fire alarm system until the plans are approved and the electrical permit is obtained.
Starting work before the required permit or approval can result in:
Rework
Delays
Inspection problems
Additional labor
Changes to installed wiring
Project scheduling issues
What Happens If Low-Voltage Work Is Installed Without a Required Permit?
If work requiring a permit is performed without obtaining the required permit, the project can encounter problems during inspection or later permitting.
Potential consequences may include:
Corrective work
Additional inspections
Delays
Documentation requirements
Additional costs
LADBS emphasizes that construction, alteration, and repair work within the City of Los Angeles must comply with local requirements and that its services include plan review, permitting, inspection, and enforcement.
For commercial projects, addressing permit requirements before installation is generally much easier than correcting unauthorized work afterward.
How Much Do Fire Alarm and Low-Voltage Permits Cost?
There is no single price for every project.
Permit and plan-review fees depend on the type and scope of work.
For applicable fire/life-safety plan reviews, LAFD's current fee schedule, effective January 5, 2026, lists Fire/Life Safety Plan Review at the greater of 0.111% of project valuation or $1,137. Inspection and re-inspection services are listed at $379 per hour.
These are government fees and do not represent the total cost of a fire alarm or low-voltage project.
Contractor costs may include:
Site assessment
Engineering or design
Plan preparation
Permit coordination
Equipment
Wiring
Installation
Programming
Testing
Inspection support
Troubleshooting
The actual project price should be determined after reviewing the property's scope and existing conditions.
What Documents May Be Needed?
The required documentation depends on the project.
For a commercial remodel, information may include:
Property address
Existing floor plans
Proposed floor plans
Electrical plans
Fire alarm plans
Equipment specifications
Device schedules
Circuit information
System calculations
Existing system information
Equipment cut sheets
Scope of work
Applicable permit applications
For fire/life-safety projects, additional documentation may be required by the reviewing authority.
Common Low-Voltage Permit Mistakes
Assuming "Low Voltage" Means "No Permit"
This is one of the most common misconceptions.
LADBS specifically identifies circumstances where low-voltage installations require a permit.
Treating Fire Alarm Like Data Cabling
Fire alarm systems are life-safety systems and receive specific treatment under LADBS and LAFD processes.
Starting Installation Too Early
Beginning installation before required approvals can create expensive rework.
Not Checking the Jurisdiction
A property near Los Angeles may actually fall under another city's permitting authority.
Failing to Coordinate With the General Contractor
Low-voltage work often runs through ceilings, walls, doors, and electrical rooms.
Poor coordination can result in:
Conflicting trades
Blocked pathways
Damaged cabling
Relocated devices
Schedule delays
Commercial Remodels and Fire Alarm Coordination
Fire alarm work should be coordinated early with the overall construction schedule.
For example, a ceiling remodel may affect:
Smoke detector locations
Notification appliance locations
Sprinkler monitoring
Duct detectors
Fire alarm wiring
Access to existing devices
Moving walls can also change the coverage requirements or device locations.
This is why fire alarm planning should happen before construction reaches the stage where walls and ceilings are closed.
Low-Voltage Permits for Apartment Building Remodels
Apartment owners and property managers should pay particular attention to fire alarm modifications during renovations.
Projects may involve:
Common areas
Corridors
Stairwells
Parking areas
Tenant spaces
Electrical rooms
Fire alarm systems
Access control
Security cameras
A remodel that appears to be primarily architectural can still affect life-safety and low-voltage systems.
Low-Voltage Permits for Offices and Commercial Buildings
Office remodels commonly include:
New partitions
New ceilings
Security cameras
Access control
Data cabling
Fire alarm modifications
Emergency systems
The low-voltage scope should be reviewed alongside the architectural and electrical scope rather than treated as an afterthought.
Low-Voltage Permits for Retail and Restaurants
Retail and restaurant remodels can involve significant coordination because of:
Occupancy changes
New walls
Ceiling changes
Kitchen equipment
Fire protection systems
Security systems
Emergency lighting
Fire alarm devices
LAFD states that its Fire Development Services reviews new construction, change-of-use, and remodeling projects for applicable occupancies and fire/life-safety systems.
Low-Voltage Permits for Medical and Healthcare Facilities
Healthcare projects require particular attention because they can involve complex electrical and life-safety requirements.
LADBS specifically identifies healthcare facilities within the scope of Article 517 of the California Electrical Code among projects requiring electrical plan approval before a permit is issued.
If a healthcare facility is being remodeled, the electrical and fire/life-safety requirements should be evaluated before construction begins.
