What the ComSOP Covers: A System-by-System Breakdown
If you're hiring a certified commercial property inspector, you'll hear them refer to the "ComSOP" — the Commercial Standard of Practice published by CCPIA (Certified Commercial Property Inspectors Association). The 2026 ComSOP is the governing document that defines what a commercial property inspection must cover, how findings must be evaluated, and what must be reported.
Understanding what the ComSOP covers helps you know what you're getting when you commission an inspection — and it helps you understand why a properly scoped commercial inspection is a completely different product from a walk-and-talk with a general contractor.
Structural Systems
The structural inspection evaluates the building's load-bearing skeleton: foundation, floor structure, wall framing, and roof structure. The inspector looks for foundation cracking, settling, or heave; moisture intrusion in crawlspaces; evidence of past structural modification; and any condition that suggests the building's load path may be compromised.
Structural findings are documented with photographs and referenced to specific building locations. Where conditions suggest the need for further engineering evaluation, the inspector will note that recommendation in the report.
Roofing
Roofing is consistently the single most common source of significant findings in commercial inspections. Commercial roofs are large, flat or low-slope, and subjected to decades of weathering, ponding water, thermal cycling, and maintenance neglect. The ComSOP requires inspection of the roof covering, all flashing at penetrations and edges, drainage systems (gutters, downspouts, scuppers, internal drains), parapet walls, and any rooftop equipment penetrations.
For large or complex roofs — multi-story buildings, extensive flat roofs — aerial thermography is a powerful supplement to the visual inspection. Infrared imaging can reveal moisture saturation in the roof assembly before it has caused visible damage from below.
Building Envelope
The building envelope is everything that separates the interior from the exterior: exterior cladding, windows, glazing systems, doors and frames, and the sealants and transitions between them. Envelope failures are the primary cause of moisture intrusion in Bay Area commercial buildings.
The inspector evaluates: cladding condition and attachment, window seal integrity, storefront glazing condition, caulking and sealant condition at all transitions, and any visible evidence of water infiltration — staining, efflorescence, rot, or mold growth.
Plumbing Systems
The plumbing inspection covers the building's water supply and distribution systems, fixtures, water heaters, and drain-waste-vent systems. The inspector evaluates pipe materials (copper, galvanized, PVC, cast iron), visible condition, water pressure, and function of fixtures and shutoffs.
Bay Area commercial buildings often have original galvanized steel piping that has reached or exceeded its service life — a condition that's frequently invisible until a pipe fails. Water heaters over 15 years old, inadequate pressure regulation, and outdated plumbing fixtures are common findings. For older buildings, a sewer camera inspection is strongly recommended as an add-on — underground plumbing is invisible to standard visual inspection and can conceal expensive problems.
Electrical Systems
The electrical inspection covers the service entrance, main disconnect, distribution panels, branch circuit wiring, and accessible outlets and switches. Commercial electrical systems range from single-phase 200A residential-grade service (in small office conversions) to three-phase 800A or larger services in industrial buildings.
Common findings include: undersized service for current tenant demands, double-tapped breakers, outdated Federal Pacific or Zinsco panels, aluminum branch wiring in pre-1980s buildings, and inadequate GFCI protection in required locations. The inspector also evaluates exterior and site electrical, including parking lot lighting and any exposed wiring.
HVAC Systems
Heating, ventilation, and air conditioning systems are among the most expensive systems in a commercial building to replace. The ComSOP requires inspection of all heating and cooling equipment, visible ductwork, ventilation fans, thermostats, and controls.
In Bay Area commercial buildings, rooftop package units (RTUs) are the most common cooling system. Inspectors evaluate unit age, condition, refrigerant charge indicators, and filter condition. A 15+ year-old RTU that's still running may have only a few years of useful life remaining — the CapEx schedule must account for this even if the unit hasn't failed yet.
For restaurants and specialized commercial kitchens, HVAC inspection extends to Type I/II kitchen exhaust hood systems and make-up air units — a specialized scope that goes beyond standard HVAC evaluation.
Life Safety Systems
Life safety inspection covers fire suppression systems, fire alarm systems, emergency egress, and exit signage. These systems are non-negotiable in commercial buildings — failures here represent liability and code violations, not just deferred maintenance.
The inspector evaluates: sprinkler coverage (presence and visible condition — not a functioning test), fire alarm panel and detector presence, emergency lighting function, exit sign illumination, egress door hardware (panic devices, proper swing direction, clearances), and corridor and stairway widths. Fire door assemblies — a frequently overlooked item — require annual inspection per NFPA 80 and are evaluated as part of the life safety scope.
Interior Finishes and Common Areas
Interior inspection covers floors, walls, ceilings, restrooms, stairways, and common areas. The inspector is looking primarily for evidence of past or ongoing moisture intrusion — the most significant interior finding — as well as trip hazards, damage from deferred maintenance, and conditions that would require immediate remediation.
Restrooms receive particular attention: fixture condition, ventilation, ADA compliance indicators, and evidence of plumbing leaks. Stairways are evaluated for handrail height and continuity, tread condition, nosing, and head clearance.
Site and Grounds
The site inspection covers parking lots, site drainage, retaining walls, fencing, exterior lighting, and landscaping as it affects the building (root intrusion, overgrown vegetation against cladding). Parking lot condition — paving, striping, drainage, and ADA-compliant stall layout — is often a significant finding in older Bay Area commercial properties.
Proper site drainage is critical in California's climate: winter storms can expose drainage deficiencies that have been building for years. The inspector evaluates grading, surface drainage patterns, area drain conditions, and any evidence of ponding or erosion.
What the ComSOP Doesn't Cover
It's equally important to understand what falls outside the ComSOP's scope:
- Environmental assessment — Phase 1 and Phase 2 ESA are separate specialty services
- Concealed conditions — the inspection is visual; we don't open walls or excavate
- Operating equipment testing — we observe and evaluate, but don't perform load tests
- Elevators and escalators — noted and referenced for specialty evaluation, not operated
- Tenant improvements — the inspection covers base building conditions; TI quality is typically a separate evaluation
Understanding these limitations is part of using an inspection report correctly. The ComSOP defines a thorough baseline — specialty services like aerial thermography, sewer camera inspection, and Phase 1 ESA fill in the gaps for specific risk areas.
Customizing the Scope
One of the most misunderstood aspects of commercial inspection is that the scope is negotiable. The ComSOP defines the minimum — but every engagement can be expanded (adding specialty services) or focused (emphasizing specific systems based on known concerns). When you request a proposal from Primo, part of that conversation is determining what scope is right for your specific property, your timeline, and your due diligence requirements.
