Basement Remodeling in West Allis, WI

West Allis Basement Remodeling for Prewar and Postwar Homes
Allis-Chalmers opened an enormous plant here in 1902, and the industrial suburb of West Allis took shape around it. Houses filled in block by block for the next half century. By the 1990 Census, the median home in the city dated to 1951. Basements from those years were often built for furnaces, laundry and storage rather than living space.
That history shapes our work here. A lot of projects are basement renovations of rooms someone finished long ago. Others start with waterproofing and only then move on to a family room. Adding a basement bathroom is another popular way to get more out of a compact older house.
How West Allis Handles Basement Permits
The city’s municipal code fee schedule sets out separate permit types for one- and two-family homes. An alteration needs a building permit and plan review. Electrical, plumbing and HVAC work each carry a permit of their own. For a quick check on a specific project, the city keeps a Do I Need a Permit? page and an online application portal. On our jobs, we file the applications and coordinate inspections with the city.
An Older Housing Stock With Real Quirks
West Allis’s 1996–2000 Consolidated Plan, using 1990 Census figures, found 48.8% of homes were built before 1950. It put 93.5% before 1980. Among owner-occupied homes, 40.2% predated 1940, well above the regional share. Older lower levels can bring low beams, uneven floors and wiring added piece by piece over the years. Before we design anything, we measure head height, look closely at the walls and note what needs updating.
What the August 2025 Storm Taught West Allis
West Allis took a preliminary 8.94 inches of rain on August 9–10, 2025, according to the Wisconsin State Climatology Office. State Fair Park closed as water ponded across the grounds. MMSD reports that a clogged trash rack at McCarty Park overtopped and flooded basements downstream. For eligible homes in its service area, MMSD’s Pipe Check program offers incentives to disconnect foundation drains and reroute sump discharge. We deal with drainage first, so new finishes never sit on top of an unsolved water problem.

West Allis Basement FAQs
Can a basement in an older West Allis house be finished?
Most can, but it depends on head height, moisture and wall condition. City planning data shows nearly half of West Allis homes were built before 1950. We check those details during our visit and explain what’s realistic.
What permits does a West Allis basement remodel need?
The city’s fee schedule lists a building permit and plan review for alterations to one- and two-family homes. Electrical, plumbing and HVAC work each need a separate permit. We apply for the ones your project requires.
Did the August 2025 flooding reach West Allis basements?
Yes. MMSD reported that a clogged trash rack at McCarty Park overtopped and flooded basements downstream. The city logged a preliminary 8.94 inches of rain. If your basement took on water, we look at drainage before any remodeling starts.
Is there help paying to keep clear water out of my West Allis sewer lateral?
MMSD’s Pipe Check program offers incentives for one- and two-family homes in its service area. It covers work like foundation drain disconnection and sump discharge rerouting. Payments go to MMSD-approved contractors, so contact one of them to confirm eligibility.
