Fire Alarm Plan Check in Los Angeles: Common Reasons Plans Get Rejected
Getting a fire alarm system approved in Los Angeles involves more than preparing drawings and submitting them for review. Fire alarm plans must provide enough information for the reviewing authorities to determine whether the proposed system meets applicable fire, electrical, building, and life-safety requirements.
For projects in the City of Los Angeles, fire alarm plans may be reviewed through the Los Angeles Department of Building and Safety (LADBS) and the Los Angeles Fire Department (LAFD), depending on the project and scope of work. LAFD's Fire Life Safety Plan Review specifically includes fire alarm and other fire/life-safety systems.
A plan may receive correction comments when information is missing, inconsistent, incomplete, or does not demonstrate compliance with applicable requirements.
For property owners, apartment owners, property managers, general contractors, developers, and business owners, understanding common fire alarm plan-check problems can help prevent unnecessary delays.
Cyber Shield Security works with customers throughout Los Angeles and surrounding communities on fire alarm and security projects.
Quick Answer: Why Do Fire Alarm Plans Get Rejected in Los Angeles?
Fire alarm plans are commonly returned for corrections when they contain incomplete drawings, missing calculations or equipment information, incorrect device locations, inadequate circuit information, missing approvals, or details that do not demonstrate compliance with applicable requirements.
LADBS maintains electrical plan-check correction information, and its published electrical correction list includes fire-warning-system requirements involving Fire Department approval, approved power sources, circuits, listed equipment, wiring methods, circuit separation, and equipment catalog information.
A plan-check correction does not necessarily mean the entire project is rejected permanently. In many cases, the plans are corrected and resubmitted for additional review.
What Is a Fire Alarm Plan Check?
A fire alarm plan check is the review of submitted drawings and supporting information to determine whether the proposed fire alarm system complies with applicable requirements.
LAFD explains that one of the primary functions of its plan check process is to review plans submitted for permits and prepare correction notices when necessary.
Depending on the project, the plans may show:
Fire alarm control panel
Smoke detectors
Heat detectors
Manual pull stations
Horns and strobes
Duct smoke detectors
Notification appliances
Annunciators
Fire sprinkler monitoring
Waterflow switches
Tamper switches
Power supplies
Batteries
Circuits
Wiring
Equipment specifications
Other system components
The purpose is to show how the proposed fire alarm system will work and how it will be installed.
Common Reasons Fire Alarm Plans Get Rejected or Returned for Corrections
1. Incomplete Fire Alarm Drawings
One of the most basic problems is an incomplete plan.
A reviewer needs enough information to understand the proposed system, including where devices will be installed and how they connect to the system.
Problems may include:
Missing floor plans
Missing device locations
Missing fire alarm control panel
Missing notification appliances
Missing circuit information
Missing system details
Incomplete room or area identification
Inconsistent drawings
A plan that does not clearly communicate the complete system can generate correction comments.
2. Fire Alarm Device Locations Are Missing or Incorrect
Device placement is an important part of fire alarm design.
Plans may receive corrections when they do not adequately identify required devices or when device locations do not correspond with the building layout and applicable requirements.
Examples include:
Smoke detectors
Heat detectors
Manual pull stations
Horns
Strobes
Duct detectors
Notification appliances
The plan should accurately represent the proposed installation.
3. Missing Fire Alarm Calculations
Fire alarm systems may require supporting calculations to demonstrate that the system has adequate capacity.
Depending on the project, documentation may address:
Battery capacity
Voltage drop
Notification appliance loading
Power supply capacity
Circuit loading
Standby requirements
Missing or incomplete calculations can result in plan-review corrections.
4. Missing Equipment Information or Catalog Cut Sheets
LADBS's published electrical correction list specifically calls for catalog cut sheets showing electrical ratings for equipment such as the fire alarm control panel (FACP), power expanders, annunciators, and devices.
This information helps reviewers verify that the proposed equipment is appropriate for the design.
A plan submission can encounter problems when:
Equipment information is missing
Model numbers are unclear
Equipment specifications are incomplete
Drawings and cut sheets do not match
Proposed equipment changes between documents
5. Fire Alarm Equipment Is Not Properly Identified
Fire alarm plans should clearly identify the equipment being proposed.
For example, the drawings should not simply show a generic symbol without enough information to determine what equipment is being installed.
The reviewer may need to know:
Manufacturer
Model
Device type
Electrical characteristics
Compatibility
Listing or approval information
LADBS's electrical correction guidance states that fire-warning equipment must be listed by a city-recognized testing laboratory and approved by the State Fire Marshal.
6. The Power Supply Is Not Adequately Addressed
Fire alarm systems require an appropriate power source.
LADBS's published correction list states that the fire-warning system must be supplied from an approved source.
Plans can therefore receive corrections when the power arrangement is unclear or does not adequately demonstrate compliance.
Supporting information may include:
Primary power
Dedicated circuits
Secondary power
Batteries
Power supplies
Circuit protection
7. Circuit Information Is Incomplete
Fire alarm plans should clearly show how system components are connected.
LADBS's correction list includes requirements concerning the branch circuit supplying the fire-warning system.
Potential issues include:
Unclear circuit identification
Missing circuit information
Incorrect power source
Inadequate circuit documentation
Inconsistencies between the drawings and electrical plans
8. Fire Alarm Wiring Is Not Properly Identified
Fire alarm wiring methods are another area that can generate corrections.
LADBS's published electrical correction list states that fire-warning system conductors are to be installed in metal raceways unless specifically approved for exposed installation.
The plans should clearly communicate the proposed wiring method rather than leaving the installation method unclear.
9. Fire Alarm Circuits Are Not Properly Separated
Fire alarm circuits may have separation requirements from other electrical circuits.
LADBS's correction guidance states that power-limited fire alarm circuit conductors or cables are to be run separately from other circuits except where specifically permitted.
A plan that does not clearly address circuit separation may receive correction comments.
10. The Fire Department Approval Is Missing
For applicable projects, coordination with LAFD is an important part of the process.
LADBS's electrical correction list states that the fire-warning system must be approved by the Fire Department before approval of the final plans.
LAFD also specifically provides Fire Life Safety Plan Review for applicable projects involving fire alarm systems.
This is one reason it is important to determine the required review path before submitting the plans.
11. Plans and Specifications Do Not Match
A common practical problem is inconsistency between different project documents.
For example:
The floor plan shows one device model
The equipment schedule shows another
The catalog cut sheet shows a third
The circuit diagram uses different equipment
The panel schedule does not match the drawings
Even if each individual document looks reasonable, inconsistencies can create questions during review.
A coordinated submission is easier to review.
12. Existing Conditions Are Not Properly Addressed
Fire alarm modifications to existing buildings can be more complicated than new construction.
The designer or contractor may need to understand the existing:
Fire alarm control panel
Wiring
Detectors
Notification appliances
Power supplies
Sprinkler monitoring
Duct detectors
Monitoring equipment
If the proposed plans do not accurately address the existing system, corrections or field issues may occur later.
Fire Alarm Plans for Existing Buildings
Existing-building projects deserve particular attention.
A property owner may want to:
Replace an old fire alarm panel
Add smoke detectors
Add strobes
Modify notification appliances
Add sprinkler monitoring
Expand an existing system
Replace outdated equipment
However, the existing system may not be compatible with the proposed equipment.
Before preparing final plans, a contractor should evaluate the existing system and determine what can realistically be reused.
Fire Alarm Plan Check for New Construction
New construction can involve a different set of coordination challenges.
Fire alarm plans may need to coordinate with:
Architectural drawings
Electrical plans
HVAC
Fire sprinklers
Emergency power
Ceiling plans
Mechanical systems
Other low-voltage systems
Starting the fire alarm design late in the construction process can create conflicts with other trades.
What Happens When LAFD Finds Corrections?
When a plan review identifies deficiencies, correction comments may be issued.
LAFD describes correction notices as part of its plan-check function.
The general process is:
Plans are submitted.
The reviewing agency evaluates the plans.
Corrections are identified if necessary.
The designer or contractor reviews the comments.
Plans are revised.
Corrected plans are resubmitted.
The reviewing agency performs another review.
Once requirements are satisfied, the plan can proceed toward approval.
The number of review cycles depends on the project and the corrections involved.
Does a Plan Correction Mean the Fire Alarm Project Is Denied?
No.
A plan being returned for corrections is different from permanently denying a project.
Correction comments generally identify issues that need to be addressed before approval.
The goal is to resolve the comments and demonstrate that the proposed system complies with the applicable requirements.
LAFD's plan-review process specifically includes the preparation of correction notices as part of its review function.
How to Reduce Fire Alarm Plan-Check Corrections
Start With a Complete Site Evaluation
For an existing property, understand what is already installed before designing the replacement or modification.
Coordinate the Drawings
Make sure architectural, electrical, fire alarm, and related drawings agree.
Verify Equipment
Confirm that equipment shown on the plans matches the proposed equipment documentation.
Include Required Calculations
Do not wait until a reviewer requests calculations if they are applicable to the project.
Clearly Show Wiring
Provide enough information to communicate the proposed wiring methods and circuits.
Address Power Requirements
Clearly identify the system's power sources and supporting information.
Review Before Submission
A detailed internal quality-control review can identify inconsistencies before the plans reach the reviewing agency.
Respond to Corrections Carefully
When corrections are issued, address each comment rather than making unrelated changes that can create additional questions.
Who Can Prepare Fire Alarm Plans in Los Angeles?
Fire alarm plans should be prepared and signed by the appropriately qualified professional or contractor for the project.
LADBS documentation for certain separately submitted fire alarm plans states that the fire alarm plan must bear the stamp, signature, and date of a California registered professional Electrical Engineer or a licensed C-10 contractor responsible for the design and content of the plan.
The exact requirements can depend on the project and applicable approval pathway.
Property owners should confirm the appropriate design and licensing requirements before hiring someone to prepare the plans.
Do Fire Alarm Plans Need LADBS and LAFD Approval?
Potentially, yes.
The exact process depends on the project.
LADBS handles applicable building and electrical plan-check and permitting functions, while
LAFD reviews applicable fire and life-safety systems. LAFD's plan-review system specifically identifies Fire Alarm Plan Review as a review type.
For a particular project, the applicable agencies and submission requirements should be confirmed before work begins.
Can You Install a Fire Alarm System Before the Plans Are Approved?
For projects requiring plan approval, property owners should not begin applicable fire alarm work before the required approvals and permits are obtained.
LADBS documentation states that fire alarm plans must be submitted and checked before the applicable electrical permit is issued 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 too early can result in:
Rework
Device relocation
Wiring changes
Inspection problems
Construction delays
Additional labor costs
How Much Does Fire Alarm Plan Review Cost in Los Angeles?
Government fees vary according to the project and applicable service.
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.
LAFD also lists an expedited plan-review service with additional fees.
These are government fees and do not represent the total cost of a fire alarm project. Contractor costs for design, equipment, installation, programming, testing, monitoring, and inspection support are separate.
