Home inspection in Big Lake.

What we see in Big Lake homes.

Big Lake was called Humboldt until 1867, and a railroad station built in 1871 shipped ice cut from its lakes to Twin Cities iceboxes. The town then became a summer vacation destination with cabins, and later an exurb whose residents commute to the metro. The population grew from 6,063 in 2000 to 10,060 in 2010 and reached 11,686 in 2020. The city lies along the Elk River, and a channel on its north side connects Big Lake to Mitchell Lake, so lakeshore lots and 2000s subdivisions sit side by side.

That history sets two kinds of inspection. Older lake cabins that became year-round houses may have been added onto, with crawlspaces, uneven insulation, older wiring and plumbing that was never meant for winter. Subdivision houses from the boom years get a close look at attic ventilation, grading that has settled, flashing and mechanical systems. Near the shore, sump pumps, drainage and any retaining walls deserve attention. Sherburne County is EPA Radon Zone 1, and MDH recommends every Minnesota home be tested.
