Garages in Southeast Michigan Homes: The Overlooked Inspection Point

When buyers walk through a home in Wayne, Oakland, or Macomb County, most of the attention goes to the kitchen, bathrooms, basement, and roof. The garage is often treated as an afterthought — a place to park the car and store the lawnmower. But garages, especially in older Metro Detroit neighborhoods, come with their own set of inspection concerns that can affect safety, insurance, and resale value.

Attached Garages and Fire Separation

One of the most important things an inspector checks on an attached garage is the separation between the garage and the living space. This barrier is designed to slow the spread of fire and keep exhaust fumes from entering the home. Common issues we find in Southeast Michigan homes include:

• Gaps or damage in the drywall between the garage and adjoining rooms
• Missing or improperly rated doors between the garage and house
• Openings around pipes, wiring, or ductwork that were never sealed

These are rarely dramatic findings, but they matter — both for safety and because they're commonly flagged in inspection reports, which can lead to negotiation during a sale.

Detached and Alley Garages: A Detroit Staple

Many older Detroit-area neighborhoods were built with detached garages, often accessed from a rear alley. These structures were frequently built decades ago and have aged very differently than the main house. Common issues include:

• Settling or cracked slabs, especially where alley pavement has heaved or deteriorated
• Deteriorated wood framing near the roofline or door track
• Outdated electrical wiring feeding the garage, sometimes not properly grounded
• Roofs well past their service life, particularly on garages that haven't been touched in 20+ years

Because detached garages are a separate structure, they're sometimes overlooked by sellers who focus improvement dollars on the house itself. That makes them a common source of surprises during a purchase inspection.

Garage Doors and Openers

Garage door safety features are a quick but important check. Inspectors look at:

• Auto-reverse function when the door meets resistance
• Photo-eye sensors near the floor, which are often missing or misaligned on older setups
• Manual release mechanisms and general door balance

These are inexpensive to fix but are worth confirming before closing, especially in homes where the door and opener may not have been serviced in years.

Water Intrusion and Slab Condition

Garage floors take a beating from Michigan winters — road salt, snowmelt, and freeze-thaw cycles all contribute to cracking and surface deterioration. Inspectors also look for signs of water entering along the base of the walls, which can point to grading issues outside or a garage floor that sits below the surrounding grade.

Why It's Worth a Second Look

A garage may not be the centerpiece of a home sale, but it's part of the property and part of the inspection. Whether it's an attached two-car garage in the suburbs or a classic detached alley garage in Detroit proper, these spaces age on their own timeline and deserve the same attention as the rest of the home.

If you're buying, selling, or simply maintaining a home in Southeast Michigan, a full inspection that includes the garage can help you understand exactly what you're dealing with — before it becomes a surprise.
