Learn when Fire Marshal review may affect a commercial permit in Fairfax County, including life safety, occupancy inspections, fire systems, and opening delays.
8/27/20265 min read
If you’re planning a commercial project in Fairfax County, the building permit is not always the only review that matters.
For many commercial spaces, Fire Marshal review can also affect the project.
This may involve life safety, exits, fire protection systems, commercial kitchen hoods, occupancy inspections, emergency lighting, and how the space is used.
For business owners, contractors, and tenants, this is important because Fire Marshal-related items can affect approval, inspections, and opening timelines.
_____________________________________________________________________________________________________
What Is Fire Marshal Review?
Fire Marshal review focuses on fire safety and life safety requirements.
For commercial projects, this may include:
exits
occupant load
emergency lighting
exit signs
fire-rated walls
fire alarms
sprinkler systems
commercial kitchen hoods
fire suppression systems
storage hazards
occupancy inspections
The goal is to make sure the space can be used safely and that fire-related requirements are addressed before occupancy.

When Fire Marshal Review May Be Needed
Fire Marshal review may come up for commercial projects such as:
restaurant build-outs
office build-outs
warehouse build-outs
tenant build-outs
change of use projects
assembly spaces
commercial kitchen projects
spaces with fire alarms or sprinklers
spaces requiring occupancy inspections
projects involving special fire safety conditions
Not every project has the same requirements.
A small office alteration may be simpler than a restaurant, warehouse, or assembly space. But fire safety should still be considered early.

Fire Marshal Review and Occupancy
For commercial spaces, Fire Marshal review can connect to occupancy approval.
A business may need to complete inspections or approvals before opening.
This can matter when:
a new tenant moves in
the use of the space changes
a tenant build-out is completed
a commercial space opens to the public
fire safety systems are involved
a Non-Residential Use Permit is required
If you want to understand the occupancy side more clearly, see what a Certificate of Occupancy is in Fairfax County.
_____________________________________________________________________________________________________
Occupancy Inspections
An occupancy inspection may be required before or after a business occupies a space.
This can depend on the type of business, the use group, the project scope, and Fire Marshal requirements.
The inspection may look at whether the space is ready for safe use.
Items that may be reviewed include:
exits
exit signs
emergency lighting
fire extinguishers
fire alarm systems
sprinkler systems
commercial kitchen systems
storage conditions
access paths
occupancy-related fire safety items
This is why occupancy and Fire Marshal items should not be left until the last minute.
_____________________________________________________________________________________________________
Fire Marshal Review and Tenant Build-Outs
Tenant build-outs often change how a commercial space is laid out.
That can affect fire safety.
A tenant build-out may involve:
new walls
new rooms
revised exits
new lighting
new occupancy layout
revised storage areas
new equipment
fire alarm or sprinkler coordination
If the floor plan changes, the fire safety review may need to confirm that the new layout still works.
If you’re planning a tenant project, see whether you need a permit for a commercial tenant build-out in Fairfax County.

Fire Marshal Review and Restaurants
Restaurant projects often involve more Fire Marshal coordination than basic commercial spaces.
This may include:
commercial kitchen hoods
fire suppression systems
cooking equipment
exit paths
occupant load
emergency lighting
exit signs
seating layout
storage areas
fire extinguishers
If the restaurant has cooking equipment that requires a hood or fire suppression system, coordination becomes even more important.
If your project includes kitchen hood work, see commercial kitchen hood permit requirements in Fairfax County.

Fire Marshal Review and Office Build-Outs
Office build-outs can also involve Fire Marshal-related review.
This may include:
exit access paths
door swings
emergency lighting
exit signs
fire alarm coordination
sprinkler coordination
occupant load
furniture layouts
conference rooms
open office areas
Even if the office work seems simple, layout changes can affect exits and life safety.
If you’re planning office work, see whether you need a permit for an office build-out in Fairfax County.
_____________________________________________________________________________________________________
Fire Marshal Review and Warehouse Spaces
Warehouse spaces can create different fire safety questions.
The review may involve:
storage layout
high-piled storage, if applicable
exit paths
occupant areas
warehouse offices
equipment areas
fire extinguishers
sprinkler systems
fire department access
occupancy inspection requirements
A warehouse may look simple because it has open space, but fire safety review can still be important depending on storage, use, and layout.
If you’re planning warehouse work, see whether you need a permit for a warehouse build-out in Fairfax County.
_____________________________________________________________________________________________________
Fire Alarm and Sprinkler Coordination
Some commercial projects may involve fire alarm or sprinkler work.
This can happen when:
walls are added
ceilings are changed
tenant layouts are revised
occupancy changes
sprinkler coverage is affected
fire alarm devices need relocation
a new system is required
If these systems are involved, the drawings should be coordinated early.
Fire protection systems should not be treated as separate from the main design. They can affect ceilings, walls, equipment locations, and inspections.
_____________________________________________________________________________________________________
Emergency Lighting and Exit Signs
Emergency lighting and exit signs are common review items in commercial spaces.
They help people find exits during emergencies or power outages.
The drawings may need to coordinate:
exit sign locations
emergency light locations
electrical plans
life safety plans
exit paths
door locations
If the life safety plan shows one route but the electrical drawings do not support it, review comments may follow.
_____________________________________________________________________________________________________
Change of Use and Fire Marshal Review
Change of use projects can trigger Fire Marshal questions.
For example:
an office becomes a restaurant
a warehouse adds customer-facing areas
a retail space becomes an assembly space
a storage space becomes a business use
a tenant changes the way the space is occupied
A different use can affect occupant load, exits, fire protection systems, storage conditions, and inspections.
If your business is changing how a space will be used, see whether you need a permit for a change of use in Fairfax County.
