Garages in Southeast Michigan Homes: What Inspectors Check Before an Overlooked Space Becomes an Expensive Surprise

When buyers walk a home in Wayne, Oakland, or Macomb County, most of their attention goes to the kitchen, bathrooms, basement, and roof. The garage often gets a quick glance and little else. But garages in Southeast Michigan carry their own set of issues, especially in older neighborhoods where detached garages were built decades ago and attached garages weren't always constructed with today's safety standards in mind. A thorough inspection treats the garage as a real part of the structure, not an afterthought.

Pre Closing Inspection evaluates garages as part of every residential inspection across Metro Detroit, looking at structure, safety systems, and water management the same way we would for any other part of the home.

Why Garages Deserve a Closer Look

Detroit-area housing stock includes a huge number of older detached garages, many dating back to the 1940s through 1960s. These structures have often settled, shifted, or been patched together over the years. Attached garages bring a different concern: the connection between the garage and the living space needs proper fire separation, since a garage fire or carbon monoxide buildup can spread into the home if that barrier has been compromised.

Structural Condition

• Foundation and slab: Cracking, heaving, or settlement is common in older detached garages, especially those built on shallow footings.
• Roof and framing: Sagging rooflines, deteriorated trusses, and water staining point to long-term moisture intrusion.
• Siding and trim: Wood-framed detached garages are prone to rot at the base, particularly where grading slopes toward the structure.

Fire Separation and Safety

• Walls and ceiling between garage and living space: Gaps, missing drywall, or improper materials reduce the barrier that slows fire and fume spread.
• Self-closing doors: The door between an attached garage and the house should close and latch on its own.
• Penetrations: Wiring, plumbing, or ductwork passing through the shared wall should be properly sealed.

Electrical and Garage Door Systems

• Outlets and lighting: Garages should have properly protected circuits, especially near any water source or workspace.
• Garage door operation: Inspectors check the automatic opener's safety reverse function, cable condition, and spring balance.
• Panel access: Many older homes route electrical panels through the garage, so clear access and proper labeling matter.

Drainage and Water Intrusion

Detached garages in particular tend to sit at grade without the same waterproofing attention given to a home's foundation. Inspectors look at how water moves around the structure, whether gutters (if present) direct water away, and whether the slab shows signs of chronic moisture.

What This Means for Buyers and Owners

A garage with significant structural or fire-separation issues can be a meaningful repair cost, and it's one area that's easy to underestimate during a quick walkthrough. Whether you're buying a home with a detached garage from the 1950s or an attached two-car garage built more recently, having it evaluated as part of a full inspection gives you a clearer picture of what you're taking on, well before closing day arrives.
