Home inspections in Davison, from the City of Flags to Potter Lake
We cover Davison from our Grand Blanc office: the City of Davison, the City of Flags, on its 1.98 square miles around M-15 and Davison Road; Davison Township, which surrounds it and runs out to Potter Lake and Hasler Lake on the Lapeer County line; and Richfield Township to the north, with Richfield Center and the Holloway Reservoir, all in ZIP 48423. The city is compact older streets from its village days, the township is 1960s and 1970s subdivisions plus the 1990s to 2020s ones that followed, and Richfield is acreage, lake lots and manufactured homes, on county water in the districts and wells beyond them, so the add-ons that matter most here are a radon test, a water test on every well, a well and septic inspection outside the water districts, and a sewer scope on the city's older streets.
Every inspection is done by a certified inspector and the digital report is in your inbox the same day. Thermal imaging of the heating, cooling, plumbing and electrical systems and of any area showing signs of water intrusion is included in every home inspection, along with a drone view of the roof when the weather allows and a sump pump test. We test; we never repair or remediate, so nothing in the report is a sales pitch. A home inspection starts at $425; the final price depends on the size and age of the home, which is why the instant quote asks for the address.
0%
of homes in the City of Davison were built before 1980, and the median house dates from 1968; Davison Township's median is 1981 (Census ACS 2020 to 2024). Lead paint and asbestos flooring, siding and insulation were still in use. We test for both.
0%
of Davison radon tests came back above the EPA fix-it level of 4 pCi/L (13 of 101 in ZIP 48423 on EGLE's map), above the county's 9%. Test anyway; the only way to know is to test.
0%
of Richfield Township's homes are manufactured homes, against 6.2% in Davison Township and 2.7% in the city (Census ACS 2020 to 2024). Piers, tie-downs and the underbelly get checked, with the crawlspace robot where an inspector cannot fit.
What buyers run into in Davison
A 1968 median in the city, a 1981 median in the township
The median home in the City of Davison was built in 1968 and 85% of the city's homes went up before 1980; Davison Township's median is 1981 with 49% pre-1980 and 25% built in 2000 or later, and Richfield Township's is 1987 with 30% built in 2000 or later (Census ACS 2020 to 2024). Davison was a village from 1889 and a city from 1938, so the streets around the M-15 and Davison Road core carry the oldest stock; the township nearly tripled between 1960 and 1980, and those ranches and split-levels get checked for solid aluminum branch wiring (1965 to 1973) and the panel brands that fail. Lead paint was legal until 1978 and asbestos was still common in flooring, siding, insulation and ceiling texture into the 1980s, so anything of that age gets a lead test (from $100) and, if you plan to pull up floors or siding, asbestos sampling (from $300, with or without a home inspection): flooring installers, including Home Depot's, will not pull up pre-1980 vinyl or linoleum without an asbestos test (Home Depot's own installation guidance says so), so we sample flooring, siding and insulation and send it to an accredited lab. We recommend a sewer scope (from $150) on any home built before 1980, any home that has been a rental, and any lot with mature trees near the sewer line, because roots are what break clay and cast iron pipe.
Three water systems, and the county's arsenic hot spot
The City of Davison runs its own wells: groundwater for about 5,000 people, in compliance with federal standards in the April to June 2024 data, with arsenic detected at 2.17 parts per billion (the limit is 10) and hardness around 170 parts per million, so expect scale in the water heater. We could not pull the city's lead service line inventory, so we look at the line where it enters the house. Davison Township and Richfield Township homes on public water get Lake Huron water treated by the Genesee County Drain Commissioner through the Karegnondi pipeline. Outside the water districts the house is on a private well, and Richfield Township is the county's arsenic hot spot, with wells found significantly over the 10 parts per billion limit; the fix is reverse osmosis or municipal water. The Genesee County Health Department says naturally occurring arsenic runs through the county's groundwater, so a private well here gets our water test (from $175), which covers arsenic along with coliform bacteria, nitrates, nitrites and lead.
Radon
Michigan EGLE (the Department of Environment, Great Lakes, and Energy) says about 1 in 4 homes in Michigan tests above the EPA action level of 4 pCi/L. Davison runs above the county: 13 of the 101 tests in ZIP 48423 on that map came back above that level, 13% against 9% for Genesee County. A 48-hour radon test starts at $200 when added to a home inspection and runs during the inspection.
Septic outside the districts, three lakes, Kearsley Creek, and Richfield's manufactured homes
County sewer serves Davison Township's districts and Richfield's; outside them the house is on a septic field. Genesee County has no county-wide time-of-sale rule for wells and septic systems and Davison has no point-of-sale inspection that we know of, so the buyer's inspection is the only look the house gets before closing. The well and septic package starts at $500 when added to a home inspection, or the well alone from $275 and the septic alone from $300. Potter Lake, Hasler Lake and the Holloway Reservoir on the Flint River are the lake lots here, and docks and seawalls on inland lakes are permitted through EGLE. A seawall inspection is $150 when added to the home inspection. Kearsley Creek near Davison carried a flood warning on April 4, 2026, so a creek-side lot gets a look at flood zone, grading and basement walls. Manufactured homes are 14.5% of Richfield Township's housing (Census ACS 2020 to 2024). Where a crawlspace or the underbelly of a manufactured home is too tight or too wet to enter we send in our crawlspace robot (an Uplink Robotics inspection crawler; the maker says only 22 have been sold in Michigan, and three of them are ours) so it gets photographed instead of skipped. Our mold inspection (from $275) is done by an IAC2-certified inspector: thermal imaging and moisture meters to find the source, spore-trap air samples and surface samples, and accredited lab results that name the species. The EPA's rule of thumb is that anything that stays wet longer than 24 to 48 hours will usually grow mold, and a finished basement hides exactly that.
Services and starting prices in Davison
Prices are starting points. Add-on services (radon, well and septic, water, mold, sewer scope, termite, lead, pool and spa) are priced as shown when added to a home inspection; booked on their own they are quoted separately. Asbestos sampling starts at $300 with or without a home inspection. Thermal imaging of the heating, cooling, plumbing, electrical and water-intrusion areas is part of every home inspection; the energy-efficiency scan of windows, doors and insulation is the add-on. The final price depends on the size and age of the home, and the instant quote gives you a firm number before you book. Commercial building inspections are quoted by the building.
