Grafton, WI — Mobile Home Park Investments

Grafton is a historic village in Ozaukee County, situated on the Milwaukee River about 20 miles north of downtown Milwaukee. With a population of approximately 12,000 and a character that blends small-town heritage with Milwaukee metro economic connectivity, Grafton occupies a distinct niche in the southeastern Wisconsin manufactured housing market.

This guide covers mobile home park investing in Grafton, Wisconsin — examining demographics, employment anchors, lot rent data, zoning, infrastructure, and how Grafton connects to the broader Milwaukee MSA investment thesis.

Grafton Market Overview

Grafton sits within Ozaukee County — one of the Milwaukee metro’s wealthiest counties and historically among the state’s highest-income communities. The village’s position on the Milwaukee River has shaped a charming downtown core, while its US-43/I-43 access connects residents efficiently to Milwaukee employment centers to the south and Sheboygan to the north.

The population of roughly 12,000 includes a mix of long-term Ozaukee County residents, Milwaukee commuters who value suburban space, and blue-collar workers employed in Grafton’s own manufacturing base. Median household income in Grafton exceeds $75,000, and single-family home prices have risen sharply — with many homes now listing above $300,000 — creating meaningful demand for affordable housing alternatives.

Why Grafton for Manufactured Housing Investment

Grafton’s appeal for mobile home park investors stems from its status as an affordable housing island within one of Wisconsin’s most expensive counties. Ozaukee County’s overall wealth means the conventional housing market prices out a significant portion of the local workforce — service workers, manufacturing employees, and young families who earn solid incomes but cannot accumulate the down payments or afford the monthly costs of conventional homeownership.

Manufactured housing communities in and near Grafton serve this demographic with dignity and stability. Long-term residents in Grafton-area parks tend to be owner-occupiers of their homes who rent the land — a profile that supports low turnover and consistent rent payments. The Wisconsin mobile home park investing guide provides state-level context for this market type.

Local Lot Rent Data and Trends

Lot rents in Grafton and the northern Milwaukee metro area range from approximately $355 to $440 per month as of 2025. The northern suburbs — Grafton, Port Washington, Cedarburg — command slightly lower lot rents than the Milwaukee County core markets, reflecting lower overall cost structures while still benefiting from metro employment access.

Ozaukee County parks have seen lot rent growth averaging 3–5% annually over the past five years, with occupancy typically at or near 95–100% in established communities. The limited supply of manufactured housing in this high-income county creates structural demand that supports long-term rent growth.

Zoning and Permitting Landscape

Grafton operates under Village of Grafton zoning regulations, with manufactured housing communities requiring appropriate zoning district classification or conditional use permits. Ozaukee County also maintains county-level zoning for unincorporated areas, and investors should clarify jurisdictional authority for any specific parcel.

The regulatory environment in Grafton and Ozaukee County broadly is cautious about new manufactured housing development, given the county’s predominantly high-income, single-family residential character. This caution protects existing parks from supply competition and reinforces the scarcity premium attached to well-located manufactured housing communities.

Infrastructure: City Water and Sewer

Grafton is fully served by village-operated municipal water and sanitary sewer systems. The water utility draws from the Milwaukee River watershed, with treatment facilities meeting state and federal standards. Sanitary sewer connects to the Milwaukee Metropolitan Sewerage District regional infrastructure.

City water and sewer connectivity is a significant operational advantage for mobile home park investors. Parks in Grafton connected to village utilities avoid the risk of well system failures, septic compliance issues, and the capital expense of private utility upgrades — all of which can erode returns in rural markets.

Proximity to Milwaukee MSA Employment Centers

Grafton’s position 20 miles north of Milwaukee via I-43 places residents within 25–35 minutes of Milwaukee’s major employment hubs, including the downtown business district, the I-94 industrial corridor, and the hospital and healthcare systems concentrated in Milwaukee’s northern suburbs. Local Grafton employers include Chart Industries and the Sigma-Aldrich distribution operations, providing on-site employment that reduces commute burdens for park residents.

To the south, Menomonee Falls and Brookfield add additional employment depth within the commute shed of Grafton-based residents.

Q: How does Grafton compare to Milwaukee County markets for park acquisition?
