General Detroit Inspection Questions
Do I really need an inspection on a rehab property in Detroit?
Yes. Especially on a rehab. Renovated Detroit homes sometimes have permitted, well-executed work. They also sometimes have cosmetic updates covering deferred structural or system issues. Fresh paint and new kitchen cabinets don't tell you anything about the electrical panel, the condition of the drain lines, or whether the basement gets water. An inspector who can distinguish quality renovation work from a lipstick-over-problems situation is worth every penny.
How long does a Detroit home inspection take?
Expect 3-4 hours for a typical Detroit bungalow or Foursquare. Larger homes, homes with complex systems, or homes with significant deferred maintenance can run 4-5 hours. Older homes with original systems require more time because the inspector is evaluating components they don't see in newer construction. Don't book anything after the inspection that you can't reschedule.
What should I look for when hiring an inspector in Detroit?
Michigan requires home inspector licensing through LARA. Verify the license is current. Beyond that, ask specifically about their experience with pre-1950 construction. Ask if they've inspected homes in the specific neighborhood you're buying in. Detroit Craftsman bungalows, Indian Village Colonials, and Boston-Edison Tudors each have characteristic issues. An inspector who's seen hundreds of them will catch things an inspector used to suburban new construction might miss.
Many experienced Detroit inspectors are InterNACHI or ASHI members. Both organizations provide inspector databases with verified credentials.
Lead Paint and Hazardous Materials
Is there lead paint in Detroit homes?
Yes. If a home was built before 1978, assume lead paint is present somewhere in the building. In Detroit, that covers nearly every home in historic neighborhoods. This isn't unique to Detroit, but the age and concentration of older housing stock makes it a near-universal finding here. A standard home inspection identifies deteriorating paint and high-risk surfaces. Full XRF lead testing requires a certified lead inspector.
The EPA's lead-safe work practices apply to any renovation work on pre-1978 homes. Factor this into renovation budgets.
Should I get a lead inspection in addition to the home inspection?
If you have children under 6, yes. The standard home inspection doesn't test for lead; it identifies visible conditions that could pose risk. A certified lead inspector or risk assessor can test paint, dust, and soil. Detroit has a history of lead exposure issues, and the City has resources through the Detroit Health Department for buyers concerned about lead risk.
What about asbestos?
Asbestos was used in a wide range of building materials through the 1970s: pipe insulation, floor tiles, ceiling tiles, siding, roofing materials, and duct insulation. In Detroit's older housing stock, you'll encounter it in some form in many homes. Standard inspections don't test for asbestos, but inspectors note suspect materials. If you see pipe wrap that looks like corrugated gray tape or 9-inch floor tiles from the 1950s-60s, those are common asbestos-containing materials. Testing through an environmental firm runs $200-400. Undisturbed asbestos in good condition is typically managed in place rather than removed.
Electrical and Structural Questions
My inspector found knob-and-tube wiring. How big a deal is this?
Knob-and-tube (K&T) wiring is very common in Detroit homes from the 1920s-40s. By itself, K&T in good condition isn't necessarily an emergency, but there are real concerns. It lacks a ground wire, which limits what you can do with modern appliances and GFCI protection. It cannot be covered by insulation without risk. And decades of amateur modifications may have introduced splices and connections that create hazards.
Insurance companies are increasingly reluctant to cover homes with active K&T wiring. Full rewiring in a Detroit bungalow typically costs $8,000-14,000. Larger homes or homes with more complex situations run higher. This is a budget item worth factoring into your offer price.
What's wrong with a 60-amp electrical panel?
A 60-amp panel was sufficient for the electrical loads of a 1940s home. Modern households with multiple appliances, air conditioning, EV chargers, and modern lighting use significantly more power. A 60-amp panel limits what you can run simultaneously and typically can't support modern circuit requirements. Upgrading to 100-amp or 200-amp service costs $1,500-3,500 depending on whether the service entrance needs to be updated as well.
What foundation issues are common in Detroit?
Detroit's older homes have a range of foundation types: poured concrete, concrete block, brick, and stone rubble foundations all appear in early 20th century construction. Settlement cracks in poured concrete are common. Efflorescence (white salt deposits) on block or brick foundations indicates past water infiltration. Mortar deterioration in older brick or stone foundations is routine maintenance.
Serious concerns are different: diagonal stair-step cracks in block foundations can indicate active soil movement, horizontal cracks in block walls indicate lateral pressure from soil, and soft or crumbling mortar in older foundations may indicate structural deterioration. When in doubt, ask your inspector whether they'd recommend a structural engineer for a second opinion. A structural evaluation runs $400-600 and answers questions a home inspector can't.
Water and Basement Questions
How common is basement flooding in Detroit?
Very common. Detroit operates a combined sewer system that handles both stormwater and sanitary sewage in the same pipes. During heavy rain events, the system can surcharge, forcing sewage back up through floor drains into basements. This is distinct from groundwater seepage, though both happen.
Ask your inspector specifically about the sewer backup protection in the home. A floor drain backflow preventer or overhead sewer conversion significantly reduces sewer backup risk. Evidence of past flooding includes water staining on walls, efflorescence, paint peeling at the base of walls, and modifications to the drain system. The Great Lakes Water Authority has information about basement backup protection programs.
The inspector found water staining in the basement. Should I walk away?
Not necessarily. Most Detroit basements have experienced some water at some point. What matters is the source, frequency, and whether it's been addressed. A single episode of sewer backup that left a stain 10 years ago is different from active seepage through the foundation walls every spring.
Ask your inspector to characterize the finding: is this active, periodic, or historical? Ask whether there's evidence of recent water (efflorescence, fresh staining, odor) versus old staining in a dry environment. Then factor the remediation cost into your offer. Waterproofing systems in Detroit basements typically cost $5,000-15,000 depending on scope.
Should I get a radon test?
Yes. Michigan's southern Lower Peninsula has significant radon-prone areas, and Wayne County (Detroit) falls within that zone. The Michigan EGLE radon program provides maps and resources for residents. Radon testing costs $100-150 as an add-on to your home inspection. If results come back above 4 pCi/L (the EPA action level), mitigation runs $800-1,500. It's one of the higher-value add-on tests given the health significance and low cost of mitigation.
