New Berlin home improvement: painting, roofing and remodeling for a postwar suburb
New Berlin's population grew fivefold between 1950 and 1970, and half its homes were built in 1978 or earlier. That puts much of the city inside Wisconsin's lead-paint cutoff, at the age when roofs, siding, windows and kitchens come up for replacement.

A suburb built fast after the war
New Berlin became a city in 1959, and the Encyclopedia of Milwaukee records its population rising from 5,334 in 1950 to 26,901 in 1970. The Census Bureau's 2020–2024 estimates put the median home at 1978 and the share built before 1980 at 52.5%. Only 4.0% predate 1940, so this is not an old-house city in the Milwaukee sense. It is a city where a large share of houses date from the 1950s through the 1970s and are now 50 to 70 years old.
Two things follow from that. First, a house built before 1978 may carry lead paint under its later coats, and Wisconsin regulates paid work that disturbs it: exterior scraping on a 1960s house crosses the 20 sq ft outdoor threshold quickly, and any window replacement counts regardless of size. Second, those houses predate Wisconsin's Uniform Dwelling Code, which covers homes started on or after June 1, 1980, so alterations to them follow the city's own requirements rather than the state code by default.
The newer half of New Berlin, built from the 1980s on, raises different questions: roofs, siding and windows that may still be original. Those are dwelling-code houses, so a re-roof follows the state's two-layer limit and, on low-slope roofs over heated space, its ice-dam protection rule.
What homeowners in New Berlin most often need
Lead-safe exterior painting
On New Berlin's pre-1978 houses, exterior painting is mostly prep: washing, scraping, spot-priming bare wood and feathering edges so the new coat doesn't telegraph old failures. That scraping falls under Wisconsin's lead-safe rules, which set containment, restricted methods and cleanup. Ask any painter for the DHS lead company and renovator certificates before you sign.
Exterior PaintingWindows from the 1960s and 1970s
Windows of that age often leak air and stick in their frames. ENERGY STAR windows for Wisconsin's Northern zone must now reach a U-factor of 0.22 or lower. Because any window replacement on a pre-1978 home is regulated lead work, and because New Berlin's permit list does not address windows, settle both questions before a window and door project starts.
Windows & DoorsKitchens with a permit built in
New Berlin's permit table marks a kitchen remodel as needing building, electrical and plumbing permits, and the city charges double fees when work starts before the permit is issued. Build the permit into the schedule of any kitchen remodel, and expect a 1970s kitchen to reveal older wiring and plumbing once the cabinets come out.
Kitchen RemodelingCounting layers before re-roofing
A roof replacement on a 1960s or 1970s house starts with how many layers are already there. Under Wisconsin's dwelling code a roof with two layers cannot be covered again; for older houses, confirm the city's rule. Tear-off also lets the deck be checked and ice-and-water membrane go down at the eaves, where ice dams do their damage.
RoofingNew Berlin permits: what the city says, and what it leaves open
New Berlin's permit table is clear about interior work. A kitchen remodel needs building, electrical and plumbing permits, and "Additions & Alterations (Interior or Exterior)" need a permit. The city warns of "double fees charged for starting work before a permit is issued." Applications are made at City Hall rather than online, and inspections are handled by SafeBuilt, LLC, which the city has partnered with for inspection services.
Exterior replacement is less clear. The permit list and the code sections reviewed for this page do not say whether re-roofing, re-siding or window replacement needs a permit. The city's fee schedule does carry a $55.00 residential line for "Reroofing, residing and trim," but that schedule has no effective date printed on it. Call the inspection office at 262-797-2445 before an exterior project and ask directly.
Homeowners doing their own work have a limit as well: the homeowner privilege does not extend to remodeling over 1,500 sq ft. The southeast Wisconsin permit guide compares New Berlin with other communities in Waukesha County.

Prospect, Calhoun and the Muskego line
Two older place names, Prospect and Calhoun, survive inside the city; both are part of the City of New Berlin for permits. New Berlin shares its southern boundary with Muskego, and the two cities' histories are tied: Muskego incorporated in 1964 after a dispute over land annexed to New Berlin.
Questions from New Berlin
Do I need a permit to replace my roof in New Berlin?
The city's published permit list doesn't say. Its fee schedule lists a $55.00 residential fee for "reroofing, residing and trim," which suggests a permit exists, but the schedule is undated. Call New Berlin's inspection office at 262-797-2445 before work starts; starting without a required permit means double fees.
Is my New Berlin house affected by lead-paint rules?
If it was built before 1978, paid work that disturbs paint beyond small thresholds, or replaces any window, falls under Wisconsin's lead-safe renovation rule. With a median build year of 1978, roughly half of New Berlin's homes are in that range. The lead-safe renovation guide explains what a compliant job looks like.
Who inspects remodeling work in New Berlin?
SafeBuilt, LLC, under contract with the city. The permits themselves are applied for at New Berlin City Hall.
