A borrower in Michigan called me last spring and said, "I want to subdivide." Ten minutes later it turned out he wanted to split 20 acres into four parcels. That is not a subdivision in Michigan. It is a land division, and it is a lot faster.

The words sound the same, but the process, the cost, and the timeline are very different. Here is how to tell them apart.

What is the difference between a land split and a subdivision?

A land split divides a parcel into a few lots with a simple approval. A subdivision creates more lots through a full plat review.

A land split, also called a lot split, land division, or partition, cuts one parcel into a small number of new parcels. It usually needs a survey and an application, not a full plat. A subdivision creates more lots, needs a plat drawn by a surveyor, and goes through a longer county review, sometimes with new roads.

Every state and county sets its own rules, so the line between the two moves. The only way to know is to read the local ordinance or call the planning office.

What is a land division in Michigan?

A Michigan land division is a split done under the Land Division Act, without a plat, as long as you stay within the number of divisions the law allows.

Michigan's Land Division Act lets owners divide a parent parcel into a limited number of new parcels without platting. Each new parcel still has to meet local zoning for size and width, and the local government must approve it. Go over the allowed number of parcels and you need a full plat under the Act.

The number of divisions is based on the size of the parent parcel. Under the old rule, the first 10 acres allowed up to 4 parcels. Once you go over the allowed number, the split has to meet the Act's platting requirements.

What changed in Michigan's Land Division Act in 2025?

Public Act 58 of 2025 raises the default for the first 10 acres from 4 parcels to 10, starting March 24, 2027.

Under PA 58 of 2025, the first 10 acres of a parent parcel can be divided into up to 10 parcels, up from 4. The new statewide default starts March 24, 2027. Since March 24, 2026, cities, villages, and townships can pass their own ordinances allowing more divisions sooner. Rules for larger parcels mostly stayed the same.

Sources: Mika Meyers and Van Buren County. Honigman notes the rules for parcels over 10 acres and for further splits after 10 years did not change.

For land investors, this is a big deal. More parcels on the same acreage without a plat means more lots to sell, sooner. But every parcel still has to meet local zoning, legal access, and septic rules. Check with the township before you buy, since some have already passed their own ordinance.

What do other states call a land split?

Lot split, minor subdivision, short plat, partition, or land division, depending on the state and county.

The name changes from place to place. Many counties call a small split a minor subdivision. Washington calls it a short plat. Oregon calls a split into two or three parcels a partition. Michigan calls it a land division. The idea is the same: a few lots, a simpler approval, and no full subdivision review.

More on the county side in minor vs. major subdivision, and the state rules for ten states in subdivision rules by state.

Takeaway: ask the county what a small split is called there, how many lots it allows, and who approves it.

Is a land split or a subdivision better for a land investor?

For most investors, a split. It is faster, cheaper, and usually fits inside a 2 year loan.

A split on an existing road can often be approved in weeks, with no road to build and no planning commission. A full subdivision can take months and cost a lot more. Unless the numbers only work with many lots, I would start with the split. You can always split again later if the rules allow.

See how long plat approval and recording take for timelines.

Can I get a loan on land I plan to split?

Yes. We lend on land you plan to split or subdivide, up to 80% of price if the split records at closing.

Our subdivide loan pays up to 80% of the purchase price if the split or plat records at closing and every lot passes perc with a conventional system. If it records later, we lend 65% at closing and 15% more when it records. The loan stays at or under 65% of our value.

We need at least 2 acres per loan, legal access, and business purpose. Full terms are on the subdivision loan page, and our Michigan land loans page covers that state.
