Waukesha County, Wisconsin Eviction Risk: Low

Waukesha County scores 2.8/10 (Low) on the eviction-risk index, making it one of the more landlord-friendly counties in Wisconsin eviction laws. That figure is the average across 29 cities, and it reflects a county where renter share is modest at 25.1%, poverty sits at just 5.5%, and average rent runs $1,408 per month with a rent-burden rate of 27.2%. For investors comparing markets across the state, Waukesha County sits at rank 45 of 72 Wisconsin eviction laws counties, meaning 44 counties carry more risk and only 27 are more landlord-friendly, placing it squarely in the middle third rather than the low-stress extreme.

The intra-county range tells a more nuanced story. Individual city scores run from 2.6 at the low end to 4.2 at the high end, a spread of 1.6 points that is wide enough to matter when choosing a submarket. Landlords who treat Waukesha County as a monolithic block will miss meaningful differences in tenant stability and legal exposure from one municipality to the next.

The cities inside Waukesha County

The highest-risk municipality in the county is Eagle, scoring 4.2/10, followed by Oconomowoc at 3.8/10 (population 19,080) and Wales at 3.7/10. Brookfield (3.6/10, population 41,273) and Sussex (3.6/10, population 12,066) round out the upper-risk tier. These are not distressed communities by typical measures, but their scores reflect structural factors that raise the probability of eviction filings relative to the county average.

At the other end, Muskego scores 2.9/10 (population 25,406), Pewaukee comes in at 3.1/10, and both New Berlin and Menomonee Falls sit at 3.2/10. The county seat, Waukesha, matches the county average exactly at 2.8/10 across a population of 71,233. Risk is genuinely hyper-local here: a landlord operating in Muskego eviction risk faces materially different conditions than one a few miles away in Oconomowoc eviction risk, even though both fall within the same county boundaries.

State-level laws that apply here

Wisconsin state law under Wis. Stat. § 704 (Landlord and Tenant) governs every tenancy in Waukesha County. For non-payment of rent, landlords must serve a 5-day notice before proceeding; lease violations carry a 14-day cure notice; and ending a tenancy without cause requires 30 days. Wisconsin eviction laws does not require just cause for non-renewal, and the state preempts any local rent-control ordinance, so landlords face no rent caps here. The Wisconsin eviction laws eviction process, from notice through a lockout on an uncontested case, typically takes 21 to 45 days; a contested matter can extend to 45 to 120 days. Court filing fees run $95 to $175, sheriff lockout fees add $50 to $150, and attorney fees commonly range from $500 to $3,000, making Wisconsin eviction costs a real budget line for any landlord who needs to pursue a removal.

On the tenant side, Wisconsin eviction laws's retaliation statute (Wis. Stat. § 704.45) and habitability rules (Wis. Stat. § 704.07) set standard obligations, but source-of-income is not a protected class under state law. Landlords should also note that the state requires at least 12 hours advance notice before entry.

With a county-wide poverty rate of just 5.5% and a renter share of 25.1%, the tenant pool across Waukesha County skews stable, though the city grid above shows that conditions vary enough between Eagle, Oconomowoc eviction risk, and the lower-risk suburbs that submarket selection remains worth the diligence.
