Residential vs. Commercial Inspection: Key Differences
Whether you are purchasing a single-family home in New Ulm, a duplex in Mankato, or a commercial building in St. Peter, understanding the type of inspection you need is essential. Residential and commercial inspections serve different purposes, follow different standards, and cover different systems.
Residential Home Inspections
A residential inspection covers single-family homes, condos, townhomes, duplexes, and manufactured homes. These inspections follow the InterNACHI Residential Standards of Practice and evaluate the home as a prospective buyer or current owner would use it.
What a Residential Inspection Covers
- Structure - Foundation, framing, floors, walls, roof structure
- Building envelope - Roofing, siding, windows, doors, insulation
- Mechanical systems - HVAC, plumbing, electrical, water heater
- Interior finishes - Walls, ceilings, floors, stairs, railings
- Safety items - Smoke detectors, CO detectors, GFCI outlets, handrails
- Site conditions - Grading, drainage, driveways, walkways, retaining walls
Property Types We Inspect

- Single-family homes - From historic homes in downtown New Ulm to new construction in Eagle Lake
- Duplexes and multi-family - Investment properties common in Mankato's rental market near MSU
- Condominiums - Unit-specific inspections including shared building components
- Townhomes - Row-house style properties with shared walls

Commercial Property Inspections
A commercial inspection covers retail spaces, office buildings, warehouses, mixed-use properties, restaurants, and multi-unit apartment buildings. These inspections are more complex and evaluate the property from a business operations and investment perspective.
What a Commercial Inspection Covers (Beyond Residential)
- Life safety systems - Fire suppression, emergency exits, ADA compliance, fire alarm systems

- Flat roofing - TPO, EPDM, modified bitumen, ponding water, membrane condition
- Environmental concerns - Asbestos, lead paint, underground storage tanks, Phase I considerations
Duplex and Multi-Family: Where Residential Meets Commercial
Duplexes and small multi-family properties (2-4 units) in Mankato and New Ulm fall into a unique category. They are residential buildings used as investment properties. Our inspection covers:
- Each unit individually (kitchen, bath, bedrooms, living areas)
- Shared systems (roof, foundation, main electrical panel, common plumbing)
- Separate utility metering (important for landlord cost management)
- Fire separation between units (required by code)
- Egress compliance for each unit (bedroom window size and height requirements)
- Rental code compliance considerations
