Lindenhurst Window Well Covers & Basement Windows
Lake Linden, the 31-acre lake in the middle of Lindenhurst, has no natural inlet. It is fed by storm pipes draining residential land — which is a fairly literal description of how water moves through this village. Sand Lake, partly in the village and partly in Lake Villa Township, sits along Route 132 and runs about 101 acres.
Lindenhurst incorporated in 1957 and built out steadily after that: 37% of its housing went up between 1970 and 1989, another 45% between 1990 and 2009, and the median home dates to 1989. Roughly 82% of the stock sits inside that 1970-to-2009 window — full-depth basements with steel wells now twenty to fifty years old.
A lake fed by storm pipes
Lake Linden runs about 31 acres with a mean depth under five feet, sits in the North Mill Creek sub-basin of the Des Plaines River watershed, and outlets over a dam toward Hastings Lake. Its shoreline has been almost entirely residential since the early 1960s. Sand Lake is bigger and deeper — around 101 acres, up to 32 feet — with roughly 86% of its shoreline developed.
What that adds up to is a village where the storm system and the lakes are effectively the same system. In July 2017, parts of Lake County took more than seven inches of rain in 24 hours; about 3,500 residents reported flood damage countywide and more than 375,000 sandbags went out.
Lindenhurst is a certified community under the Lake County Watershed Development Ordinance, which means the village enforces those stormwater rules itself rather than handing them to the county. Practically, that means your questions have a local answer — Village Hall, not a county office.
Permits and egress in Lindenhurst
Lindenhurst moved to the 2018 International Residential Code effective January 1, 2025, replacing the 2012 edition it had been running on. Permits issued before that date still fall under the old code. The village notes the change also lines it up with Lake County and the Lake Villa Fire Protection District, which provide its inspection services.
The permit rule here is a clean line, and it is the one that catches people. Replacing a window at the same size does not require a permit. Replacing a window at a new size does — and so does a finished basement. Cutting an egress opening is by definition a new size, so it needs one.
Building & Engineering is at 2301 E. Sand Lake Road; the number is (847) 356-8252. We did not find Lindenhurst-specific amendments to the egress or window well rules, so the 2018 IRC governs as written — but the village's amendment section is not published in full online, so confirm with them before you order materials.
