Commercial Building Inspection Checklist & How to Prep

A commercial building inspection covers a lot more ground than a residential one: hence the need for a checklist, even as the investor. The buildings are larger, the systems are more complex, and the stakes for buyers, investors, and tenants are significantly higher.

Knowing what gets evaluated and how to prepare for the process can make a real difference in how smoothly things go and how useful the final report turns out to be.

This guide covers what a commercial inspection looks at, what clients can do to prepare, and what to expect from the report.

What Does a Commercial Building Inspection Cover?

A commercial inspection is a comprehensive evaluation of the property’s physical condition.

At CFBI, that means examining every major system and structural component, inside and out, using certified inspectors with commercial-specific training. Let’s go over what a thorough inspection addresses.

what's covered in a commercial building inspection

Structural and Foundation

The structural system is evaluated first. Inspectors look for foundation cracks, uneven settling, signs of water intrusion at the base, bowing or bulging walls, and any visible indicators of structural stress.

In Central Florida, sinkhole activity and high water tables are regional factors that get particular attention.

Roof System

The roof is one of the most expensive components to replace on a commercial property and one of the most important to evaluate carefully. Inspectors assess the roofing membrane, drainage systems, penetrations, flashing, and overall condition.

CFBI uses drone technology for roofs that are unsafe or inaccessible to walk, ensuring no area goes unexamined.

Exterior Envelope

This covers the full exterior of the building: walls, windows, doors, caulking, sealants, and any cladding or facade materials. Inspectors look for signs of moisture intrusion, deterioration, poor sealing, and deferred maintenance that could lead to larger problems.

Electrical Systems

Commercial electrical systems are evaluated for code compliance, capacity, panel condition, wiring, grounding, and visible hazards.

Outdated wiring, overloaded panels, and improper installations are common findings in older Central Florida commercial buildings.

Plumbing

Inspectors check supply and drain lines for leaks, corrosion, and proper function. Water pressure is tested, fixtures are operated, and visible pipe conditions are documented.

In Florida’s climate, pipe deterioration from heat and humidity is a consistent issue in buildings that have not had recent plumbing updates.

HVAC Systems

Heating, ventilation, and air conditioning systems are evaluated for condition, age, apparent maintenance history, and operational status. In Central Florida, commercial HVAC systems run hard year-round.

Inspectors check rooftop units, air handlers, ductwork condition, and thermostat function. End-of-life HVAC equipment is one of the most common major capital expenditure findings in commercial reports.

Life Safety Systems

Fire suppression systems, sprinkler heads, alarm panels, emergency lighting, and exit signage are all evaluated during a commercial inspection. These systems are not just a code requirement; they are a liability issue for any buyer or tenant taking on a commercial property.

Interior Components

Walls, ceilings, floors, doors, and interior finishes are inspected for damage, deterioration, moisture staining, and deferred maintenance. Inspectors note cosmetic issues separately from functional or structural concerns so clients can prioritize accordingly.

Parking, Site, and Drainage

The exterior grounds are part of the inspection, too. Parking lot condition, accessible pathways, exterior lighting, landscaping, proximity to the building, and stormwater drainage are all evaluated.

In Florida, drainage issues around commercial properties are a frequent and significant finding given the state’s rainfall patterns and flat terrain.

ADA Accessibility

While CFBI inspectors are not certified ADA compliance specialists, the inspection will flag visible accessibility concerns at entrances, restrooms, ramps, and common areas. These observations can be a useful starting point for a formal ADA compliance review if needed.

How to Prepare for a Commercial Building Inspection

Preparation on your end makes the inspection more efficient and the report more complete. Here is what to have ready before the inspector arrives.

Gather Key Documents

  • Prior inspection reports or repair records for the property
  • Maintenance logs for HVAC, roof, elevators, and other major systems
  • Permits for any recent renovations or additions
  • Utility bills from the past 12 months (helpful context for HVAC efficiency findings)
  • Any environmental reports or Phase I/Phase II assessments that have been completed
  • Existing warranties on roof systems, mechanical equipment, or appliances

Ensure Access to All Areas

This is one of the most important steps. The inspector needs access to every part of the property: the roof, attic spaces, mechanical rooms, electrical panels, crawl spaces, and any locked tenant areas.

Coordinate with current tenants or building managers in advance. Restricted access during an inspection means gaps in the report, and those gaps can create problems later.

Have Utilities Active

All utilities should be on and operational on the day of the inspection. Inspectors need live electricity to test outlets, panels, and lighting. Plumbing needs to be active to check pressure and drainage.

HVAC systems need to be operable to assess function. A property with utilities shut off will result in an incomplete inspection.

Make Mechanical Equipment Accessible

Clear the area around electrical panels, water heaters, HVAC units, and any rooftop access points. Equipment that is blocked or buried behind stored inventory cannot be properly evaluated.

Know the History of the Property

If you are the buyer, ask the seller or listing broker for any known issues, recent repairs, or pending maintenance.

Sellers are not always forthcoming, but disclosed information helps inspectors know where to look more closely and helps you ask better questions after the inspection is complete.

What to Expect from the Report

CFBI provides a detailed written report with photographic documentation of all findings. The report is organized to help clients distinguish between immediate concerns, deferred maintenance items, and items to monitor over time.

For commercial clients, the report also highlights potential major capital expenditures. A roof that has two years of useful life left is a very different financial picture than one that was replaced five years ago, and the report is structured to make those distinctions clear.

Optional add-ons are available depending on the scope of the transaction:

  • Mold testing: Florida’s humidity and frequent moisture intrusion make mold a relevant concern in many commercial buildings, particularly in older properties or those with known water damage history.
  • Termite and wood-destroying insect inspections: A common add-on for commercial properties with wood-framed components or significant landscaping close to the structure.
  • Thermal imaging: Included in every CFBI inspection at no additional cost. Infrared scans help detect hidden moisture, electrical hotspots, and insulation gaps that are not visible to the naked eye.
  • Drone roof inspection: Also included where applicable. Useful for large flat commercial roofs, multi-story buildings, and any structure where walking on the roof is not safe or practical.
  • Property Condition Assessment (PCA): A more formal evaluation that follows ASTM E2018 standards, commonly required by lenders, investors, and institutional buyers as part of the due diligence process.

Related Questions

How is a commercial inspection different from a residential one?
Commercial inspections are more complex in scope, duration, and required expertise. They cover larger structures, varied building types, specialized systems like fire suppression and commercial HVAC, and often involve code considerations specific to commercial occupancy.

How long does a commercial inspection take?
It depends on the size and complexity of the property. Smaller commercial buildings may be completed in a few hours. Larger or multi-building properties can take a full day or longer, with additional time needed for report preparation. CFBI provides a customized scope and timeline with every commercial quote.

What happens if major issues are found?
The inspection report gives buyers documented, professional findings to use in negotiations. Options typically include requesting repairs before closing, negotiating a price reduction, asking for a credit at closing, or, in some cases, walking away from the transaction. The report itself is the leverage.

Do commercial properties in Central Florida have region-specific concerns?
Yes. Florida’s climate and geography create a consistent set of commercial inspection findings that inspectors in other regions rarely see as frequently.

These include sinkhole risk, high water table effects on foundations and drainage, aggressive HVAC wear from year-round heavy use, accelerated roof membrane deterioration from UV exposure and heat, and elevated humidity driving mold and moisture issues in buildings with any envelope deficiencies.

Conclusion

A commercial building inspection is one of the most important steps in any commercial real estate transaction. It protects buyers from costly surprises, gives investors and tenants a clear picture of what they are taking on, and provides the documentation needed to negotiate from a position of knowledge.

CFBI has provided commercial building inspections across Central Florida since 1988. Our certified inspectors bring commercial-specific training, advanced technology including thermal imaging and drone assessment, and a detailed reporting process designed to give clients exactly what they need to move forward with confidence.

Common Signs of Radon That Require Action Now

Radon is an invisible, odorless gas that can enter a home without any obvious warning. Many Central Florida homeowners do not realize the signs are there until a radon test reveals its presence.

While radon is more common in certain parts of the country, pockets of elevated levels exist throughout Florida. This means every home has the potential for radon exposure, no matter its age, style, or location.

Because radon cannot be seen, smelled, or tasted, the signs are not always clear. Still, there are patterns and conditions that increase risk. This guide explains the most common signs that your home may have elevated radon levels, what homeowners should watch for, and when it is time to schedule radon testing.

Why Radon Testing Matters in Central Florida

Many homeowners assume Florida is not a radon-prone state, but this is not true. According to the Florida Department of Health, one in five Florida homes tested shows elevated radon levels. This includes homes with slab foundations, crawlspaces, and even newer construction.

Central Florida’s soil and geology allow radon to collect under homes, especially in areas with:

  • Sandy soil
  • Deep foundations
  • Poor ventilation under the slab
  • Cracks or gaps around plumbing or utilities
  • High humidity keeps air movement low

Because radon has no smell or taste, the only way to confirm levels is through testing. Recognizing the conditions that increase risk helps homeowners decide when to act.

The Most Common Signs of Radon Exposure in a Home

Radon itself does not create visible stains or odors. Instead, signs appear through a combination of building conditions, indoor air quality complaints, and the home’s foundation or soil contact.

Here are the most important indicators to watch for.

1. Air That Feels Stale or Heavy in Lower Levels

Radon collects in the lowest part of a home because it enters through the soil. In Central Florida, many homes built on slabs still have areas where air becomes stagnant.

A stale or heavy feeling in:

  • Bedrooms
  • Laundry rooms
  • Hallways
  • Storage spaces
  • Finished or unfinished ground-level rooms

can indicate poor air circulation, which increases the chance that radon is accumulating.

Radon rises naturally, but homes with closed-up windows, long cooling seasons, and limited airflow can trap more of it inside.

2. Cracks in the Foundation or Slab

Cracks in concrete slabs or block walls create easy pathways for soil gases. These cracks do not cause radon, but they make it easier for radon to enter.

Common entry points include:

  • Hairline cracks across the slab
  • Cracks in block walls
  • Gaps around pipes
  • Openings around sump wells or utility penetrations

Florida’s soil shifts during rainy and dry seasons. As the ground expands and contracts, new cracks can form, giving radon more pathways inside.

3. High Humidity Levels That Make the Home Feel Damp

Radon enters from the soil, and Florida’s climate keeps moisture levels high. When a home feels damp for long periods, it often means the air is not moving well. Poor circulation allows radon to collect in the lowest parts of the home.

High humidity does not prove radon is present, but it often appears in homes with elevated levels because of:

  • Long cooling seasons
  • Reduced ventilation
  • Slab contact with moist soil
  • Indoor air that stays trapped for long periods

The EPA notes that radon levels can rise in homes that are sealed tightly or cooled for long periods without fresh airflow.

4. Lingering Odors or Stuffy Rooms

While radon itself has no smell, rooms with poor airflow often develop odors that linger. If certain rooms always feel stuffy or take a long time to air out, it may indicate that the air is not moving well enough to prevent radon from building up.

You might notice:

  • Musty or stale smells
  • Air that feels “closed off” even after cleaning
  • Rooms that become uncomfortable more quickly

Stuffy rooms do not confirm radon, but they signal airflow problems that increase risk.

5. Soil Contact Around the Home That Looks Damp All Year

Damp or wet soil around the exterior of a home can increase the chance that radon collects below the slab. Central Florida’s rainy seasons, sprinkler systems, and high groundwater all contribute to saturated soil.

Signs to watch for include:

  • Standing water near the foundation
  • Soil that stays damp long after rain
  • Landscaping that slopes toward the home
  • High water tables

Wet soil does not cause radon, but it allows gases to stay trapped close to the foundation, making it easier for radon to seep inside.

6. Long Periods With Windows Closed

Florida’s heat, storms, and humidity mean many homeowners keep windows closed almost all year. When indoor air does not circulate, radon has fewer ways to escape.

This is especially important in homes that:

  • Rely on air conditioning most months
  • Have tight seals around windows and doors
  • Are newer and built to be more energy efficient

Energy-efficient homes are great for comfort and cooling costs, but they often allow radon levels to rise more easily without regular testing.

Why Is Radon a Health Concern?

Radon is the second leading cause of lung cancer in the United States, according to the EPA.

Long-term exposure increases risk because radon particles can be inhaled into the lungs.

Children may be more sensitive to radon because their breathing rates are higher relative to their body size.

The health effects of radon come from long-term exposure, not short-term contact. This is why regular testing is important, especially during the times of year when windows stay closed, and air is less likely to move freely.

How Do Radon Levels Change Throughout the Year?

Radon levels can rise or fall depending on several seasonal factors. Many Central Florida homes experience changes due to:

  • Rainy seasons and storm moisture
  • High water tables
  • Temperature swings
  • HVAC usage patterns
  • Soil pressure changes

The EPA also notes that radon levels often spike during cooler months when homes stay closed. In Central Florida, similar increases can happen during hot summer months when air conditioners run all day.

How Does Radon Enter a Home?

Radon moves from the soil into homes through the path of least resistance. Common entry points include:

  • Foundation cracks
  • Open block walls
  • Gaps around plumbing or electrical
  • Sump pump openings
  • Crawlspaces or low-lying areas

Once inside, radon becomes trapped without proper ventilation. Because radon is a gas, it can move through even very small gaps.

What Homeowners Should Do if These Signs Are Present

If you notice any conditions on this list, the next step is simple: schedule a radon test. Testing is the only way to confirm the presence or level of radon inside a home.

Homeowners should consider testing when:

  • Buying or selling a home
  • Moving into a home built on a slab
  • Renovating or opening sealed areas
  • Living in a home with little airflow
  • Noticing persistent humidity or moisture issues
  • It has been more than two years since the last test

Radon testing is fast, affordable, and one of the most helpful steps homeowners can take to ensure a safe indoor environment.

Other Related Questions

Do Florida homes with slabs still need radon testing?
Yes. Even homes without basements can have elevated radon levels because the gas moves directly through the soil and slab.

Can radon get into newer energy-efficient homes?
Yes. Tighter construction often traps indoor air for longer periods, which can allow radon to accumulate more easily.

Is radon only a concern in older homes?
No. Radon can affect homes of any age, and newer homes can sometimes experience higher levels due to improved air sealing.

Should I test for radon before buying a home in Central Florida?
Many buyers do. Radon testing provides peace of mind and helps you understand the indoor air quality before closing.

When to Call a Professional

Call a qualified inspector when you want accurate testing and clear results. Testing is recommended when:

  • Buying or selling a home
  • Noticing poor airflow or humidity issues
  • Living in a home with slab-on-grade construction
  • It has been two or more years since the last test
  • You want to confirm the current indoor air quality
  • You live in an area known for elevated radon levels

Professionals use accurate testing equipment and provide clear results, so you know whether additional steps are needed to make the home safer.

Conclusion

Radon is a silent indoor air quality concern that can affect any home in Central Florida. While the signs are not always obvious, certain conditions and patterns make elevated radon levels more likely. Recognizing these risk factors and scheduling a radon test can help protect your home and your family.
