When it comes to commercial buildings, the structure types often predict the kinds of problems that may show up during an inspection. Whether you’re investing in a retail space, medical office, warehouse, or multifamily complex, understanding common defects by building type helps you prepare for smarter ownership.
Below, we break down key building categories, the most common issues that come with each, and why a detailed commercial inspection matters for long-term value and safety.
Office Buildings
Office buildings range from single-tenant units to high-rise types. These properties tend to rely on centralized systems and shared infrastructure, which can hide problems behind the walls or above the ceiling.
Frequent issues:
- Outdated or undersized HVAC systems
- Leaking or poorly maintained roofs
- Drafty windows or poor insulation
- Aging or overloaded electrical panels
- Water intrusion around mechanical equipment
- Expired or missing fire suppression equipment
Older buildings may also be out of step with current energy efficiency standards or Americans with Disabilities Act (ADA) accessibility requirements, which can become costly to correct if not caught early.
Retail Centers
Retail buildings include strip malls, shopping plazas, big box stores, and stand-alone shops. While they may appear well-maintained from the outside, hidden wear and tear is common.
Watch for:
- Foundation cracking from high foot traffic or nearby construction
- Roof drainage problems that cause leaks in tenant spaces
- DIY wiring or plumbing work from tenant improvements
- Faulty exterior lighting or signage
- Inconsistent maintenance between units
Tenant turnover and varying buildout quality can lead to inconsistencies from unit to unit, making a full-property evaluation essential.
Medical and Dental Offices
Healthcare buildings are designed to meet higher safety, sanitation, and structural standards than typical offices. They also rely on specialized systems that may not be obvious to an untrained eye.
Common defects:
- Corroded or improperly vented plumbing
- Inadequate electrical supply for medical equipment
- Ventilation or filtration systems that don’t meet code
- Poor accessibility for patients or staff
- Water damage or mold in storage and utility areas
Because these facilities serve the public, even small oversights can lead to compliance issues, patient safety concerns, or costly equipment failures.
Industrial and Warehouse Properties
Warehouses, manufacturing spaces, and other industrial buildings prioritize function, but they’re often subject to harsh conditions and heavy use. This creates wear patterns that can go unnoticed without a professional inspection.
Look out for:
- Roof leaks, especially from aging flat roofs
- Damaged concrete slabs or loading docks
- Rust or corrosion on structural steel components
- Poor ventilation or moisture buildup
- Outdated electrical systems are prone to overload
- Pest problems in storage areas
Poor drainage or ventilation can also lead to mold or indoor air quality issues, particularly in older spaces that were not built to current standards.
Multifamily and Mixed-Use Buildings
Multifamily properties and mixed-use developments that combine commercial and residential spaces face a unique set of challenges. From tenant complaints to shared systems, defects here can affect multiple units at once.
Typical concerns:
- Leaks or water damage in shared walls or ceilings
- Failing balconies or stairwells
- Inconsistent plumbing across units
- Fire egress violations or blocked pathways
- Mold and mildew buildup from poor ventilation
- Roof drainage issues that impact common areas
Units may have been remodeled at different times, leading to mismatched materials or undocumented changes. These can cause problems down the line if not flagged early.
Why the Types of Buildings Matter
Each building type comes with its own priorities and pain points. Understanding what those are helps you plan for repairs, budget more accurately, and avoid expensive surprises.
A thorough commercial inspection covers all visible and accessible components of the building, including the roof, structure, mechanical systems, safety features, and site conditions. For investors, property managers, and business owners, it’s a smart step that turns guesswork into strategy.
In Arizona’s climate, it’s especially important to assess HVAC performance, energy efficiency, and signs of sun and water damage. The harsh heat and seasonal rains can wear down roofing, windows, and exterior finishes faster than expected.
When to Schedule a Commercial Inspection
If you’re purchasing, leasing, refinancing, or renovating a commercial property, schedule an inspection as early as possible. This gives you time to review the report, negotiate repairs, and make informed decisions.

Frequently Asked Questions
Do you check for code violations?
We inspect for safety and functionality, and we flag anything that appears out of compliance. However, some code-related issues may need further evaluation from your local authority or a licensed contractor.
How long does a commercial inspection take?
It depends on the building’s size, layout, and systems. Smaller spaces may take a few hours, while larger or more complex buildings could take a full day or longer.
Can you inspect tenant spaces, too?
Yes. We inspect all accessible areas, including tenant buildouts, common areas, rooftops, and mechanical rooms. If you manage or lease space to others, it’s important to evaluate each unit where possible.
Do you inspect apartment complexes or condos?
Yes. Multifamily inspections are a key part of our commercial services. We evaluate individual units (as accessible) along with shared systems and structures.
Final Thoughts
Types of commercial buildings vary in structure, design, and risk. Whether it’s a warehouse with slab damage or an office with outdated fire protection, these defects can cost thousands if left unchecked.
By understanding the common issues tied to each building type, you’ll be better equipped to ask the right questions, plan smarter repairs, and protect your investment.
