How Many Students Can Legally Share a House

Before you sign a lease with four friends, check one thing almost nobody checks: your city’s cap on how many unrelated adults may share one home. It is set by the zoning ordinance, not by the number of bedrooms — and in some college towns a rented house may legally hold only one or two people, whatever the listing advertises. We read the ordinance for 34 college towns and quoted each one.

Every figure below is quoted from the city’s own code or a city-published document, with the section named. Where we could not read the ordinance, we say so rather than guess — one town is still listed that way on purpose.

A rented house may hold only one or two unrelated adults

The strictest tier, and the one that catches students out. In several of these towns the cap is lower for a rental than for a house the owner lives in.

Three, four or five unrelated adults

Still a real limit, and still lower than the bedroom count on plenty of student houses.

No limit on unrelated adults

In these towns the cap was repealed, struck down, or never written. That is worth knowing too — it means a five-bedroom house can legally hold five students.

Check this one locally — we still cannot read the regulations

One town where we will not print a number. Three others sat in this section until we opened their codes in a real browser instead of a fetcher — Akron, New Brunswick and Oxford have all moved up into the lists above. This one has not. Ring the town and ask.

The law here is moving, and not all of it in the same direction

This is not a settled area, which is exactly why a listing site will never tell you the answer. Four patterns are worth understanding before you rely on anything you read.

Some states have taken the power away. Washington barred its cities from limiting the number of unrelated people in a household, which is why both Washington towns on this page now have no cap. If you are renting in a state that has done this, the number in an old city document is not the law.

Some state courts struck the caps down. New Jersey’s Supreme Court did it in 1979, holding that counting unrelated individuals cannot survive constitutional review. New York’s courts did much the same to flat caps in the 1980s — which is why Buffalo’s ordinance carries that “functional and factual family equivalent” escape clause. It is there to keep the rule alive.

And some states expressly allow them. Virginia’s code specifically authorizes enforcing occupancy limits on single-family dwellings. Pennsylvania’s courts have upheld a three-unrelated-persons definition applied to student rentals. In those states the number on the page is the number.

One city proves occupancy by counting cars. Oxford, Mississippi sets out how it establishes a violation: “Prima facie proof of occupancy of a dwelling unit by more than three unrelated persons is established… if it is shown that the same four or more vehicles with registration to persons having different surnames or addresses were parked overnight at the dwelling unit a majority of nights in any 14-day period.” Oxford also makes it a violation for an “owner, occupant, or lessee” to permit over-occupancy — so there, unlike in most towns here, the tenant is personally on the hook. Memphis reaches housemates too, through a clause covering anyone who “knowingly assisted” in the violation.

And one state sets the floor rather than removing it. Utah bars its cities from setting a single-family limit below three where a state university sits inside the city, and below four everywhere else. Salt Lake City is capped at three because the University of Utah is within its boundary — a statute written so that university towns can be stricter than the rest of the state, which is the opposite of what Washington did.

There is a neat irony in the New Jersey line of cases. The 1990 decision that set the standard for what counts as a “family” was Borough of Glassboro v. Vallorosi — and the household in question was ten students from the college that is now Rowan. The court held they were a family. Glassboro appears on this page today with no numeric cap at all.

And one state has just written a ban aimed at college towns specifically. A Texas statute in force since 1 September 2025 bars a city from limiting how many people may occupy a home based on age, familial status, occupation, relationship status or degree of relation — but only in a home-rule city of under 250,000 people that hosts or adjoins a campus of more than 20,000 students. It is the most narrowly aimed law of its kind we have found: it describes college towns and nothing else. What survives is a floor-area test, roughly one occupant per sleeping room of at least 70 square feet with more space required for each additional person — the same shape of rule Ypsilanti already writes voluntarily. Two provisions give it teeth. A city may not require a broker or agent to hand over a lease in order to count the unrelated occupants, and an owner or tenant may sue over a violation, with attorney’s fees mandatory if they win.

And one city has moved the other way. Detroit’s limit of two unrelated adults was among the strictest of any large American city. In September 2025 the city enacted an amendment raising it to four. Every other movement on this page runs toward repeal, by statute or by court — Detroit is the one place that chose to relax its own rule while keeping it.

Michigan deserves one more sentence, because five towns here are in it. In 1984 the Michigan Supreme Court struck down a township ordinance limiting unrelated occupants, on state constitutional grounds, in Charter Township of Delta v. Dinolfo. That case concerned a township, its reach over home-rule cities is contested, and we have found no decision applying it to Kalamazoo or Detroit. These ordinances are on the books and cities do enforce them. But it belongs beside the New Jersey and New York cases as a reason not to treat a printed number as the last word.

Seven places are still publishing rules that are not the law

This is the part worth being careful about, because the stale page is usually easier to find than the current code.

None of these is a trap laid for anyone — cities are slow to retire old pages. But it means the sentence you find first may be years out of date, in either direction. Check the code section itself, and check whether it has been repealed.

They do get fixed, though, and sometimes quickly. When we read College Station’s housing pages in September 2026, one of them was still publishing the four-person rule the city had repealed a year earlier, complete with the penalties and a presumption drawn from how many cars were parked outside overnight. Within the week that page was gone. That is the argument for checking the date on whatever you are reading — and for reading the code rather than the guide to it.

How to check your own address in ten minutes

  1. Find the zoning district for the exact address. Most of these cities publish a parcel or zoning lookup where you type an address and get the district back. The cap often depends on the district, and sometimes on nothing else.
  2. Read the definition of “family” or “household” in the zoning code, not the occupancy section of the property-maintenance code. Those are two different rules: one counts relationships, the other counts square feet and bedrooms. You have to satisfy both.
  3. Check whether the owner lives there. In Kalamazoo, Mount Pleasant and Harrisonburg the answer changes the number.
  4. Check the rental license or certificate. Several of these cities publish a search where you can confirm a rental is registered and current. An expired certificate is a problem that lands on the tenant.
  5. Ask the planning office directly if anything is ambiguous, and ask before you sign rather than after. A lease for more people than the zoning allows is the landlord’s problem legally and your problem practically.

One thing this page deliberately does not do is tell you whether your particular group would qualify as a “family” under a functional test. Several of these ordinances have one, and they turn on stability and permanence — Kalamazoo’s expressly excludes groups whose living arrangement is “of a transitory or seasonal nature”. No one can tell you in advance how a city will apply that to a nine-month lease. Anyone who gives you a confident answer is guessing.

Where these figures come from

Every number above was read from a city ordinance, a city-published PDF, or a city web page, in September 2026. Where a city publishes its code only through a viewer that serves no text, we say the figure is unverified rather than reproduce one from a secondary source. Court decisions are named so you can look them up yourself.

Zoning changes, and it has been changing quickly in this particular corner of the law. Treat this page as a starting point and the city’s own current code as the authority. If you find something here that is out of date, tell us and we will fix it.
