A retail or restaurant building inspection in San Diego is a visual, non-invasive look at the structure, roof, electrical, plumbing, mechanical and accessibility features of a commercial space – documenting used-condition and deferred maintenance so a buyer or tenant understands what they are taking on. It is not a code-compliance sign-off or a permit history search, but it gives you a grounded picture before you sign.
Why retail and restaurant spaces inspect differently
Most San Diego retail and food-service buildings have been worked over by a string of past tenants. Each one added a counter here, a wall there, a new electrical sub-panel, a mop sink, a grease line – often without pulling permits, and almost never removing the previous tenant’s leftovers. By the time you walk a space, you are looking at layers of tenant improvements stacked on top of each other.
That history matters because the building you are buying or leasing is rarely the building the original architect drew. A general commercial inspection helps you see the current physical condition honestly: what works, what is worn out, what was clearly modified, and where you will want a licensed specialist or your design team to dig deeper before money changes hands.
Tenant improvements: what you are really inheriting
Tenant improvements (TIs) are the single biggest variable in a retail or restaurant deal. A previous restaurant build-out can look like a gift – hood already installed, floor drains in place, walk-in cooler still standing – or it can be a liability you pay to demolish.
During a walkthrough we document the visible condition of partition walls, drop ceilings, flooring, storefront glass, roll-up doors and built-in fixtures. We note obvious signs of unpermitted-looking work: a sub-panel feeding a kitchen with no apparent disconnect, plumbing that drains uphill, framing that was clearly added after the original construction. We cannot tell you what was permitted – that is a question for the City or County building department and your own records request – but we can flag what looks like later, lower-quality work so you can investigate.
If the space is being delivered “as-is” or in “vanilla shell” condition, the inspection becomes your baseline. It is far cheaper to know about a sagging roof structure or a failing storefront before you commit to a five- or ten-year lease and a six-figure build-out.
Used condition is the default, not the exception
Commercial tenants run equipment hard. Floors take pallet jacks and dollies, restrooms see heavy public use, HVAC runs ten-plus hours a day. Expect to see scuffed finishes, patched drywall, mismatched lighting and tired fixtures. The inspection’s job is to separate cosmetic wear from the items that actually cost real money – structure, roof, major systems and water intrusion.
Kitchen and grease systems context
Restaurant kitchens introduce systems you simply do not see in a typical office or retail space, and several of them fall outside a general inspector’s visual scope. Here is how we handle them.
- Grease interceptors and grease lines. We can visually confirm a grease interceptor is present and look for obvious leaks or overflow staining. We cannot certify capacity, confirm it meets current code sizing, or tell you it has been pumped and serviced – that is a question for the City’s industrial wastewater program and a licensed plumber.
- Floor drains and sanitary plumbing. Kitchen floors are full of drains that may or may not still flow. We check what we can run water to, but blockages and grease-clogged branch lines often hide downstream. If the building is older or the kitchen has sat unused, a sewer scope camera add-on is the only way to actually see the condition of the lines.
- Walk-in coolers and freezers. We look at the box, panels, door seals and visible refrigeration lines. Compressor performance, refrigerant charge and temperature pull-down are mechanical questions for a refrigeration technician.
- Gas piping. We note visible gas lines and connections to cooking equipment, but pressure testing and appliance certification belong to a licensed plumbing or mechanical contractor.
HVAC, kitchen hoods and Type I exhaust
Rooftop packaged HVAC units (RTUs) are the workhorses of San Diego retail. We operate them through normal controls where it is safe to do so, check for obvious age and corrosion, and note units that are clearly past their service life or short-cycling. We do not open sealed refrigerant circuits or perform load calculations – if a deal hinges on remaining equipment life, have an HVAC contractor evaluate and service each unit.
Commercial kitchen exhaust is its own world. A Type I hood with its grease ducting, make-up air and fire-suppression system is a specialist scope, not a general inspection item. We will note that a hood exists and look for obvious problems, but the suppression system, duct cleaning certification and exhaust fan must be evaluated and tagged by qualified fire-protection and hood-service companies. Treat any restaurant deal as requiring those specialists in parallel with your building inspection.
Roof penetrations and rooftop loads
Retail and restaurant roofs – usually low-slope membrane over the sales floor and kitchen – take a beating from everything bolted to them. Every RTU, exhaust fan, grease duct, refrigeration line set and plumbing vent is a penetration, and every penetration is a potential leak. Old or abandoned curbs from removed equipment are a classic source of water intrusion above a kitchen.
We assess the visible roof surface, flashings, drains and the condition of penetrations and curbs where safe access allows. Greasy buildup near hood exhaust fans is common and degrades the membrane over time. Because the roof is so often the most expensive surprise in a commercial deal, many buyers also order a dedicated commercial roof inspection and budget for ongoing care once they take ownership.
ADA and accessibility
Accessibility is one of the highest-exposure items in California retail and food service, and it deserves a clear caveat. A general inspector can point out obvious accessibility concerns – a missing van-accessible parking stall, steep entry thresholds, restrooms that look too tight for clearances, missing grab bars. We are not Certified Access Specialists (CASp), and an inspection report is not an ADA or California accessibility compliance audit.
Given how often public-accommodation businesses face accessibility claims in San Diego County, a formal CASp survey is worth serious consideration on any retail or restaurant purchase. Use our visual notes as a heads-up, not a clearance.
Where a building inspection fits in your due diligence
For most retail and restaurant deals, a focused commercial building inspection is the right starting point. If you are buying the property itself – or financing a larger asset – a broader property condition assessment rolls the building condition together with expected repair costs and remaining useful life of major systems, which lenders and partners often want to see.
Either way, the building inspection is one input among several. Pair it with the specialists called out above – pest, fire-protection, hood service, refrigeration, CASp – and with your own permit and records research, and you walk into the deal with eyes open.
