Coliving in the United States: The Zoning Question Decides Everything

Most American zoning codes regulate occupancy through a definition of family. Occupants related by blood, marriage or adoption face no numeric limit; unrelated occupants typically do, commonly capped somewhere between three and six per dwelling unit, with exceptions for licensed boarding houses where the category exists at all.

For coliving that is decisive. A six-bedroom house is a viable product in a city with a six-person unrelated cap and an illegal one across a municipal boundary with a three-person cap, with no difference in the building, the residents or the operating model. This is why two apparently comparable American cities can have completely different coliving markets.

A reform movement is now visibly moving. Colorado's House Bill 24-1007 — signed on 15 April 2024 and effective 1 July 2024 — prohibits local governments from limiting how many people may live together in a single dwelling based on familial relationship. Occupancy limits grounded in demonstrated health and safety standards, such as building and fire code, remain permitted; limits based on who is related to whom do not. Notably, the act binds local governments rather than homeowners' associations, which remain private entities.

Several other states have moved in the same direction and individual cities are revisiting their family definitions independently. Our practical guidance, and this is our judgement rather than a legal opinion: treat the state preemption question as the first filter in US market selection, then check the specific municipality, then check whether an HOA or deed restriction reimposes what the city has removed. Take legal advice on the specific address before you commit capital — occupancy law is local, changes often, and general guidance is not a substitute for it.

The Census Bureau's Housing Vacancy Survey put the national rental vacancy rate at 7.3% in the second quarter of 2026, statistically unchanged from 7.0% a year earlier and effectively identical to the first quarter. The homeowner vacancy rate was 1.2% and the homeownership rate 65.0%, flat year on year.

Median asking rent for vacant rental units was $1,531, down $48 over the quarter. That is a soft but not falling national picture, and national numbers matter less in the US than almost anywhere because the variance between metros is so wide.

The structural demand argument holds regardless: a homeownership rate stuck at 65% with 7.3% rental vacancy describes a large, permanently renting population in a market with enough slack that renters have choices. Choice is what makes product quality and service pay.

The sequence we use runs legal first, demand second, and it is deliberately the opposite of how most operators approach it. Establish whether the state has preempted relationship-based occupancy limits. If not, check the target municipality's unrelated-occupancy cap and whether a boarding house or rooming house licence offers a lawful route above it. Then check covenants and deed restrictions on the specific parcel.

Only after that does demand analysis earn its place: employment concentration, the ratio of median asking rent to a room rate you could realistically charge, in-migration, and how much of the existing shared-housing market is informal roommate arrangements rather than operated product.

Reversing that order is the most common and most expensive American mistake — a signed lease on a building in a three-person-cap jurisdiction is not a market entry, it is a liability with a rent payment attached.
