Garages and Detached Structures in Southeast Michigan Homes: What Inspectors Check Before You Park the Car

When buyers walk a property, the garage often gets a quick glance compared to the roof or basement. But in Southeast Michigan, where detached garages, older carriage houses, and converted structures are common — especially in Detroit, Dearborn, Royal Oak, and Ferndale neighborhoods — garages carry their own set of risks. A thorough inspection treats the garage as seriously as any other part of the home.

Why Garages Deserve a Closer Look

Garages take a beating from Michigan weather. Road salt, melting snow, temperature swings, and moisture from parked vehicles all add up over time. Add in the fact that many garages in older neighborhoods were built decades before current safety expectations, and it's easy to see why problems show up more often than people expect.

Structural and Foundation Issues

Detached garages, particularly in older Metro Detroit neighborhoods, often sit on shallow or minimal foundations. Inspectors look for:

• Cracking or heaving in the slab or foundation walls
• Settling that causes doors to bind or gaps to open at the base
• Roof framing sag, especially in garages with additional storage loads above
• Water intrusion at the base of walls where grading slopes toward the structure instead of away

Fire Separation Between House and Garage

For attached garages, the wall and ceiling separating the garage from living space matter more than most homeowners realize. Inspectors check for:

• Gaps, damage, or missing material in the shared wall or ceiling
• Doors between the garage and house that don't self-close properly
• Penetrations from wiring, plumbing, or HVAC that were never properly sealed

These details matter because a garage fire — often starting from a vehicle, stored chemicals, or an electrical issue — can spread into living space far faster without a proper barrier.

Electrical and Garage Door Safety

Garages are also where a lot of DIY electrical work happens. Inspectors commonly flag:

• Outlets without GFCI protection
• Improperly wired lighting or added circuits
• Garage door openers with missing or non-functioning auto-reverse safety sensors
• Worn springs, frayed cables, or damaged rollers on the door itself

Roof, Siding, and Water Management

Detached garages often get less maintenance attention than the main house. Inspectors look at the roof covering, flashing, gutters (if present), and siding condition, along with how water drains around the structure. Standing water next to a garage foundation is a common contributor to long-term settling and interior moisture.

What This Means for Buyers and Sellers

A garage in poor condition doesn't necessarily kill a deal, but it does affect negotiations and future budgeting. Buyers benefit from knowing whether they're looking at cosmetic wear or a structural issue that needs prompt attention. Sellers benefit from addressing obvious problems — a binding door, an unsealed penetration, missing GFCI outlets — before they become sticking points during negotiations.

A Small Part of the Property That Shouldn't Be Skipped

Garages may not be the most exciting part of a home inspection, but they play a real role in safety, structural integrity, and long-term maintenance costs. A licensed inspection covers the garage with the same attention given to the rest of the property, so nothing gets missed simply because it's outside the main living space.
