Buying Land in Ottawa County, Michigan

Real growth, concentrated around Holland and Grand Haven

Ottawa County is genuinely one of Michigan's fastest-growing counties, not just a reputation -- its population grew roughly 4% between 2020 and 2025, adding more than 11,500 residents and holding its position as the state's 7th-largest county, with growth reported as the 10th-fastest of any Michigan county over that period. The growth isn't evenly spread: Jamestown Charter Township, Grand Haven Charter Township, Allendale Township, and the City/Township of Holland (Holland itself straddles the Ottawa/Allegan county line) have posted some of the county's largest year-over-year gains. For a land buyer, that growth is exactly what's driving both the demand side of this market and the resource strain described below -- and a real, documented loss of farmland (more than 14,000 acres in five years by recent reporting), which the county has responded to with an active Purchase of Development Rights program that pays farmland owners for a permanent conservation easement on their land. See our dedicated conservation-easements page for Ottawa County for how that program works for a seller, and what it means if a parcel you're evaluating already carries one.

Zoning: handled city-by-city and township-by-township

Ottawa County does not appear to administer a countywide zoning ordinance of its own; instead, each city and township runs its own -- Holland Charter Township and Grand Haven Charter Township are two of many examples, each with a separately adopted zoning ordinance and map. The county's own Department of Strategic Impact plays a coordinating role by encouraging municipalities to adopt standardized land-use map titles and colors, which makes comparing zoning across the county easier to read, but that's a cartographic convenience, not a single legal zoning code. Confirm the specific city or township for any candidate parcel and go directly to that jurisdiction's own zoning ordinance.

A real, documented groundwater limit for private wells

Despite bordering Lake Michigan, Ottawa County has a genuine, well-documented groundwater problem that directly affects any buyer planning to rely on a private well. The county's deep bedrock aquifer has shown declining water levels and, in places, rising salinity, first surfacing publicly in the mid-2000s when residents of an Allendale Township subdivision reported dry faucets and farmers found themselves irrigating with salty well water. The issue was significant enough that Ottawa County formed what the Citizens Research Council of Michigan describes as the state's first county-level Groundwater Board -- a standing body that meets regularly on groundwater recharge, legislative land-use issues, and protection planning.

The practical, on-the-ground result: some townships have already restricted new groundwater-dependent development directly. Blendon Township has stopped approving new subdivision development that would rely on new wells, and Allendale Township bars new housing developments from using groundwater at all, instead requiring connection to municipal water sourced from Lake Michigan. See our dedicated well-water page for Ottawa County for what this means when evaluating a specific rural parcel here -- this is genuinely one of the most consequential, county-specific due-diligence issues in this entire research batch.

Lake Michigan shoreline: Critical Dune Areas add an EGLE permit layer

For land along or near Ottawa County's Lake Michigan shoreline, an additional state permitting layer applies on top of local zoning: Michigan designated roughly 74,000 acres along 265 miles of Great Lakes coastline as Critical Dune Areas in 1989 under NREPA Part 353, and Ottawa County's dunes (in the Holland and Grand Haven areas) are part of that program. Within a designated Critical Dune Area, construction, driveways, septic system installation, and even vegetation/contour changes generally require a separate EGLE permit -- worth confirming early for any shoreline-adjacent parcel here, since it can add real time and cost beyond whatever the local zoning ordinance already requires.

Septic: a real estate transfer evaluation requirement since 1984

Separate from the groundwater situation above, Ottawa County has required a septic and well evaluation before a property can be sold since 1984 -- one of an estimated 30 to 35 of Michigan's 83 counties with any point-of-sale septic requirement, and a genuinely long-standing rule rather than a recent addition. See our dedicated septic-systems page for Ottawa County for what the Real Estate Transfer Evaluation actually checks and how to build it into a closing timeline.
