A commercial property inspection in Maryland can be one of the most important parts of a buyer’s due diligence before purchasing a building.

Commercial properties can contain expensive systems and improvements that may require substantial capital to repair or replace. A roof, HVAC system, parking lot, electrical service or structural problem can materially change the economics of an acquisition.

The purpose of the inspection process is not simply to determine whether a building is “good” or “bad.” It is to help the buyer better understand the physical condition of the property, identify potential problems and estimate future capital requirements.

Commercial Inspection vs. Residential Home Inspection

Commercial property assessment should not automatically be approached like the inspection of a typical house.

Commercial buildings can contain larger and more complex systems, including:

• Multiple HVAC units
• Flat or low-slope roofing systems
• Three-phase electrical service
• Loading docks
• Fire suppression systems
• Elevators
• Commercial kitchens
• Large parking areas
• Industrial equipment
• Specialized plumbing

Depending on the property, the buyer may need a commercial property professional plus specialized contractors, engineers or consultants rather than relying on one general inspection alone.

What Should a Commercial Property Inspection Cover?

The appropriate scope depends on the building, its age, its use and the buyer’s plans.

Major areas that may warrant evaluation include:

• Roof
• Structure
• Foundation
• Exterior walls
• HVAC
• Electrical systems
• Plumbing
• Fire and life-safety systems
• Parking areas
• Drainage
• Loading facilities
• Interior condition
• Accessibility
• Site improvements

1. Roof

The roof can represent one of the largest potential capital expenses in a commercial building.

The buyer should try to understand:

• Roof type
• Approximate age
• Installation date, if available
• Repair history
• Remaining useful life
• Evidence of leaks
• Drainage condition
• Warranty information

For larger buildings, even a seemingly modest roofing problem can become expensive because of the amount of surface area involved.

2. HVAC Systems

Heating, ventilation and air-conditioning systems should receive careful attention, particularly in office, retail, medical and mixed-use properties.

Investigate:

• Number of units
• Approximate age
• Condition
• Maintenance history
• Service records
• Areas served by each unit
• Known repairs
• Replacement expectations

If the property contains numerous rooftop units, replacement costs can become a significant future capital expenditure.

3. Electrical System

Electrical capacity can be particularly important for industrial, manufacturing, restaurant, medical and technology users.

Depending on the property, investigate:

• Available electrical service
• Panel condition
• Distribution systems
• Three-phase power, when required
• Equipment requirements
• Electrical upgrades
• Backup power systems

4. Plumbing

The plumbing system can affect both the physical condition of the building and its suitability for the proposed use.

Potential items include:

• Water supply
• Water pressure
• Drainage
• Sewer connection
• Restrooms
• Water heaters
• Visible leaks
• Pipe condition

Restaurants, medical facilities, salons, daycare facilities and certain industrial users may require plumbing capacity beyond what the existing building provides.

5. Structure and Foundation

Structural concerns deserve specialized attention because repairs can be costly and can affect the building’s usability.

Potential warning signs can include:

• Significant cracking
• Settlement
• Water intrusion
• Damaged structural components
• Uneven floors
• Visible deterioration

If material concerns are identified, a qualified structural engineer may be appropriate.

6. Exterior Walls and Building Envelope

The building envelope separates the interior of the property from outside conditions.

Potential areas to evaluate include:

• Exterior walls
• Windows
• Doors
• Sealants
• Flashing
• Masonry
• Water intrusion
• Insulation-related concerns

Water intrusion can sometimes indicate problems extending beyond the visible interior damage.

7. Parking Lot and Pavement

Parking areas can represent a significant capital expense, particularly for retail centers, office buildings and other properties with large paved areas.

Evaluate:

• Pavement condition
• Cracking
• Potholes
• Drainage
• Striping
• Curbs
• Sidewalks
• Lighting
• Accessible parking areas

The buyer should also determine whether the available parking supports the intended use and applicable requirements.

8. Drainage and Stormwater

Water should move away from buildings and paved areas appropriately.

Potential concerns include:

• Standing water
• Poor grading
• Blocked drains
• Erosion
• Damaged stormwater facilities
• Evidence of repeated flooding

Site drainage problems can affect buildings, parking areas and future development plans.

9. Fire and Life-Safety Systems

Depending on the property, fire and life-safety systems can include:

• Sprinkler systems
• Fire alarms
• Emergency lighting
• Exit signage
• Fire extinguishers
• Emergency exits
• Other suppression or detection systems

The requirements can change depending on building use and occupancy.

10. Loading Docks and Drive-In Doors

For warehouse and industrial properties, loading infrastructure should be evaluated as carefully as the building itself.

Consider:

• Number of dock doors
• Dock condition
• Dock height
• Drive-in doors
• Door dimensions
• Truck court depth
• Trailer circulation
• Loading-area pavement

A building may have sufficient warehouse square footage but still be operationally unsuitable if its loading configuration does not work for the buyer’s vehicles.

11. Warehouse Clear Height

Industrial buyers should verify usable clear height rather than relying only on total building square footage.

Clear height can affect:

• Racking
• Storage capacity
• Material handling
• Equipment
• Future tenant demand

Column spacing and building depth can also materially affect warehouse functionality.

12. Elevators

If the property contains elevators, buyers should investigate available maintenance and inspection information.

Elevator repairs and modernization can represent significant capital costs in multi-story buildings.

Maryland’s Division of Labor and Industry administers elevator safety inspection and certification requirements. The state also administers safety programs for certain boilers and pressure vessels used in commercial establishments.

13. Boilers and Mechanical Equipment

Some commercial properties contain boilers, chillers or other centralized mechanical systems.

Buyers may need to determine:

• Equipment age
• Maintenance history
• Inspection records
• Operating condition
• Remaining useful life
• Potential replacement cost

14. Interior Condition

Interior improvements may not be structural, but they can still affect the capital required after closing.

Evaluate:

• Flooring
• Ceilings
• Walls
• Doors
• Restrooms
• Lighting
• Office buildout
• Common areas

A dated interior may be physically functional but still require substantial renovation for the buyer’s intended use.

15. Accessibility

Accessibility should be evaluated in relation to the property and proposed use.

Potential areas include:

• Accessible parking
• Routes into the building
• Entrances
• Restrooms
• Elevators
• Interior circulation

Qualified professionals should be consulted regarding applicable accessibility requirements and potential improvements.

16. Signs of Water Intrusion

Look for evidence that water has entered the building.

Possible indicators include:

• Ceiling stains
• Wall discoloration
• Damaged drywall
• Musty odors
• Standing water
• Visible deterioration

The visible damage may not identify the actual source, so further investigation may be necessary.

17. Environmental Conditions

A physical building inspection and an environmental site assessment serve different purposes.

Environmental investigation may be especially important for properties with current or historical uses involving:

• Gas stations
• Automotive repair
• Dry cleaners
• Manufacturing
• Fuel storage
• Chemicals
• Industrial operations

The Maryland Department of the Environment maintains programs dealing with brownfields and contaminated properties and recognizes Phase I and Phase II environmental site assessments within its Voluntary Cleanup Program.

Phase I vs. Phase II Environmental Assessment

A Phase I Environmental Site Assessment generally investigates the property’s historical and current environmental conditions through records, site observations and other research.

If concerns warrant additional investigation, a Phase II Environmental Site Assessment may involve sampling and testing.

Maryland’s Department of the Environment notes that, within its Voluntary Cleanup Program, Phase II investigation may be unnecessary when the Department concludes from the Phase I and other information that recognized environmental conditions are absent.

18. Review Maintenance Records

Physical inspection becomes more useful when combined with documentation.

Ask whether available records include:

• Roof repairs
• HVAC service records
• Equipment warranties
• Elevator records
• Fire system inspections
• Plumbing repairs
• Electrical work
• Capital improvements

Maintenance history can help a buyer understand how the property has been managed and identify systems approaching replacement.

19. Review Permits and Property Records

When appropriate, investigate available government records relating to construction and alterations.

Questions may include:

• Were major additions permitted?
• Were significant renovations permitted?
• Does the existing use have appropriate occupancy approval?
• Are there unresolved code issues?
• Will the buyer’s proposed use require new approvals?

The appropriate records and procedures depend on the Maryland county or municipality where the property is located.

20. Estimate Deferred Maintenance

Finding a problem is only the beginning. The buyer should try to understand its financial impact.

Potential deferred-maintenance items can include:

• Roof replacement
• HVAC replacement
• Parking lot resurfacing
• Exterior repairs
• Elevator modernization
• Plumbing repairs
• Electrical upgrades
• Fire-system improvements

Inspection Findings Can Affect the Deal

What happens after an inspection depends on the purchase agreement, negotiations and circumstances.

Depending on the transaction and contractual rights, inspection findings may cause a buyer to consider:

• Proceeding without changes
• Requesting additional information
• Obtaining specialist evaluations
• Seeking repair estimates
• Negotiating transaction terms
• Reevaluating the investment
• Exercising contractual rights when applicable

Who Might Be Involved in a Commercial Property Inspection?

Depending on the size and complexity of the property, the due diligence team may include:

• Commercial property assessment professional
• Structural engineer
• Roofing contractor or consultant
• HVAC contractor
• Electrician
• Plumber
• Environmental professional
• Civil engineer
• Fire protection professional
• Elevator specialist
• Other specialized professionals

Not every transaction requires every specialist. The scope should reflect the property and the risks identified during due diligence.

Commercial Property Inspection Checklist

Inspection vs. Full Commercial Due Diligence

The physical inspection is only one component of commercial real estate due diligence.

A buyer may also need to investigate:

• Zoning
• Title
• Survey
• Environmental conditions
• Existing leases
• Rent roll
• Operating expenses
• Property taxes
• Insurance
• Financing
• Legal documents

Factor Repairs Into Your Investment Analysis

For an income-producing property, anticipated repairs and capital expenditures can affect investment returns.

A property may appear attractive based on current Net Operating Income, but the economics can change if major capital expenditures are required shortly after acquisition.
