Home Inspection Checklist for Minnesota Buyers

If you are buying a home in New Ulm, Mankato, St. Peter, or anywhere in southern Minnesota, a professional home inspection is your best protection against hidden problems. Here is exactly what a thorough inspection covers and what Minnesota-specific issues you should know about.

The Complete Minnesota Home Inspection Checklist

Exterior Inspection

Foundation visible surfaces - Cracks, displacement, water staining, efflorescence
Grading and drainage - Does water flow away from the foundation? Minnesota's spring snowmelt makes this critical
Siding and trim - Damage, rot, gaps, caulking condition
Windows and doors - Seal integrity, operation, condensation between panes
Decks, porches, patios - Structural integrity, railing height and spacing, ledger board attachment
Driveway and walkways - Frost heave damage, trip hazards, settlement near foundation
Garage - Structure, overhead door operation, fire separation from living space, auto-reverse safety

Roof Inspection

Shingle condition - Age, curling, granule loss, storm damage
Flashing - Around chimneys, vents, skylights, and wall intersections
Gutters and downspouts - Condition, slope, extensions directing water away
Ventilation - Ridge vents, soffit vents, adequate attic airflow (prevents ice dams)
Ice dam evidence - Staining on fascia, damaged shingles at eaves, interior water damage at exterior walls

Structural Systems

Foundation walls - Horizontal and vertical cracking patterns, bowing, step cracks in block
Floor system - Joists, beams, posts, sill plates for damage, rot, or insect activity
Load-bearing walls - Evidence of structural modifications without proper support
Basement/crawl space - Moisture, standing water, sump pump operation, vapor barriers

Plumbing

Water supply pipes - Material (copper, PEX, galvanized, polybutylene), condition, leaks
Drain and waste pipes - Material, slope, condition, signs of past backups
Water heater - Age, capacity, safety devices (TPR valve, expansion tank), venting
Fixtures - Function, leaks, water pressure at each fixture
Main water shut-off - Location and operation
Sewer line condition - We recommend a sewer scope inspection for homes over 20 years old

Electrical

Service panel - Capacity (100A, 150A, 200A), condition, brand (Federal Pacific and Zinsco are known hazards)
Branch circuits - Proper wire sizing, connections, overcurrent protection
GFCI protection - Required in bathrooms, kitchens, garages, exteriors, unfinished basements
AFCI protection - Required in bedrooms and living areas in newer construction
Smoke and CO detectors - Minnesota requires CO detectors within 10 feet of every sleeping room
Grounding and bonding - Proper system grounding, gas pipe bonding

HVAC

Furnace - Age, BTU output, condition, heat exchanger integrity, combustion air supply
Air conditioning - Age, capacity, refrigerant line condition, temperature differential
Ductwork - Condition, connections, insulation, air leakage
Thermostat - Operation and programming
Humidifier - Common in MN homes, checked for operation and water damage

Attic and Insulation

Insulation depth - Minnesota Energy Code requires R-49 in attics for new construction
Vapor barrier - Proper placement on the warm side
Ventilation - Balanced intake (soffit) and exhaust (ridge/roof vents)
Bath fan venting - Must vent to exterior, not into attic (common Minnesota violation)
Signs of ice dam damage - Water staining, mold, damaged sheathing at eaves

Minnesota-Specific Issues Your Inspector Should Check

Radon

Minnesota is a Zone 1 high-radon state. Brown County (New Ulm), Blue Earth County (Mankato), and Nicollet County (St. Peter) all have elevated radon risk. We recommend radon testing with every home purchase in southern Minnesota.

Well Water (Rural Properties)

If the home uses a private well, testing for coliform bacteria, nitrates, and water hardness is important. Southern Minnesota's agricultural land use means nitrate contamination is a real concern in some areas.

Septic Systems (Rural Properties)

Homes outside city limits typically have septic systems. Minnesota requires a compliant septic system for property transfer in most counties. Ask about the system type, age, and last pumping date.

Questions to Ask Your Home Inspector

How many inspections have you performed?
Do you carry Errors & Omissions insurance?
What does your inspection cover that others might not?
Do you offer thermal imaging?
How quickly will I receive my report?
Can I attend the inspection?
