Types of Building Inspections

Permit holders must schedule inspections at various times during construction. Inspections are made to verify compliance with the adopted building codes.

Many items, such as a plumbing ground rough or an electrical service, are looked at on an individual basis by city building inspectors. Other inspections, such as electrical wall and ceiling, are made when areas of buildings are about to be covered.

Required inspections

Permits require each element be inspected prior to being covered and when all elements are completed. Permitted projects differ greatly; it is impossible to establish a pre-determined list of inspections.


Abbreviation - Inspection Type
CRI - Commercial Rough-in
A general rough-in type of inspection of electrical wiring, plumbing systems, mechanical work and structural items. Most common use of this inspection type is with apartments; however, it could be used on other commercial work.
DFT - Draftstop
Draftstop inspection of components designed to restrict the movement of air within open spaces of concealed areas of buildings such as crawl spaces, attics and floor/ceiling assemblies.
ECI - Electrical ceiling
This inspection involves the inspection of all items located in a ceiling. The components within the ceiling assembly can be covered once this inspection is approved.
EGT - Electrical generator
This inspection involves the operational testing of an on-sight emergency generator.
EPB - Electrical pool bonding
This inspection involves bonding of metallic parts such as rebar, ladders, and niche lighting.
EPW - Electrical pump wiring
Inspection of the pump and associated wiring, typically for a sewage ejection system for a private sewage disposal system. Note this inspection is performed by a building inspector and the rest of the disposal system (sewage laterals, placement of the tank, final inspection etc.) is inspected by the city's Community Services section.
ERR - Electrical residential rough-in
Inspection of electrical wiring before concealment. This is inspection type is only used when electrical work is the only code item to look at.
ESB - Electrical spa bonding
This inspection involves bonding of all metallic parts for a Spa/hot tub.
ESL - Electrical slab-inside
The inspection of conduit and boxes that are being place in an concrete slab (floor) located within the building structure.
ESV - Electrical service
The inspection of an electrical service. Upon approval of the inspection, clearance of the service is automatically forwarded to the power company.
EUG - Electrical underground
The inspection of conduit being run under ground.
EWI - Electrical wall
This is a rough-in inspection of wiring and other electrical components located within a wall.
FAT - Fire alarm test
The complete testing of an alarm system within a building, i.e. smoke detectors, pull stations. Typically this inspection is scheduled in conjunction with a final inspection or just prior to a final inspection.
FFF - Fire protection, fireline flush
Inspection of the flushing of the underground fire suppression lines to insure proper debris removal prior to connecting to the inside building standpipes or sprinkler system. The installer will flush the system to the satisfaction of the inspector at the required rate of 10' per second according to NFPA standards.
FGI - Fuel gas-inside
Inspection of all interior gas line piping and the venting of gas fired appliances. Part of the inspection includes a pressure test. After city approval is made the city will contact the proper utility company and authorize a meter.
FGO - Fuel gas-outside
The inspection of privately owned, exterior underground gas line piping. Part of the inspection includes a pressure test.
FHD - Fire protection, hood and duct system test
Inspection of the hood and duct system and testing of the proper operation of all associated mechanical equipment. The test is performed by the installer in accordance with the manufacturers requirements, the code requirements and in view of the inspector. The test may include electrical functioning, fuel shut off, dispersal of test gasses through the piping system etc•
FHI - Fire protection, hydrostatic inside sprinkler lines
Inspection of the inside wet fire suppression system lines and the witnessing of a 200 psi. hydrostatic pressure test for a minimum of two hours. All sprinkler heads should be in place and cut sheets of special heads should be on site, i.e. quick response, extended coverage etc. The same designation is used to schedule inspections on a "dry" system but the testing is with 40 psi. air pressure for a 24 hour period.
FHO - Fire protection, visual
The visual inspection of a wet or dry fire protection system. No type of test is performed.
FHT - Fire protection, halon test
The inspection and witnessing of the halon system and test. This is performed by the installer and witnessed by the inspector in conformance with the manufacturer's recommendations and code requirements.
FIN - Final
The general inspection of all completed work prior to the issuance of an occupancy permit or a certificate of compliance. This inspection is a prerequisite for a temporary certificate of occupancy.
FLH - Fire line-hydro test
The hydrostatic testing of a fire line.
FLV - Fire line-visual
The visual inspection of piping materials, thrust protection and installation of a fire line. No hydrostatic test is performed with this inspection type.
FOF - Fire protection, outside fire line
Inspection of the piping materials, thrust protection, and installation prior to being covered and the witnessing of the 2-hour minimum of 200 psi. hydrostatic pressure test for fire lines serving a building or private fire hydrants. The piping is allowed to be "shaded" or weighted down to prevent movement during the test but all pipe joints shall be left exposed for the duration of the test. Visual inspections of "minor" sections of the fire line may be approved for burial where it is critical for site work and approved by the field inspector.
FPL - Fireplace
Inspection of the masonry firebox, hearth support, and flue lining prior to the finished face being installed. Prefabricated fireplaces and their flue systems are inspected as part of the rough-in inspection for residential projects. See "RRI" inspection.
FPT - Fire protection fire pump
Inspection entails the complete performance testing of a fire pump. Test includes the flowing of standpipes.
FRC - Fire resistive ceiling
Inspection of either a floor/ceiling assembly or a roof/ceiling assembly required to have a fire rating. Among other things the inspector will look at the nail or screw pattern.
FSF - Fire protection, standpipe flow test
Inspection to witness the flowing of the standpipes to verify the proper rate of the flow and pressure as required by the Building code for the particular building involved. The test is performed by the installer and witnessed by the building inspector and Fire Department personnel. Standpipes are to be installed during construction on buildings requiring them at the time the height of the building becomes 40' above the lowest level of fire department vehicular access.
FST - Firestop
Inspection of the firestopping materials installation prior to being covered. Often on commercial projects the methods to be used are specified by the architect. It is important to make certain that materials being used are part of a UL or other approved testing laboratory system and are being installed according to the "listing" of the product and system. Firestopping on most residential projects are performed as part of the "RRI" inspection.
FTG - Footing
Inspection of the forms, trenches and all reinforcing steel prior to concrete being poured. Footings for "deck" only structures are not inspected by the city but must be installed per the code and to a minimum depth of 36" below finished grade to be below frost level. Footings, piers and grade beams on commercial projects are not inspected by the city when it is required to have an approved third party inspection agency performing this function. Contact the plans examiner on the particular project to register that special inspections will be performed and by whom.
FUG - Fuel-underground electrical
Involves the inspection of conduit(s) within a fuel dispensing area which would typically be classified as a class 1, division 1 area.
FWL - Fire resistive wall
Inspection of fire rated assemblies including rated walls, ceilings, columns, floors etc. for proper materials and installation. If the assembly is to use drywall materials the inspection must be made before mudding and taping. If multiple layers are involved each layer must be inspected prior to proceeding to additional layers or application of finish materials being applied.
MCI - Mechanical, ceiling inspection
The inspection of duct work, plenums and associated mechanical equipment located in a ceiling.
MDT - Mechanical-duct detector test
Involves the performance testing of the smoke detector(s) located within the air handling unit.
