Short-Term Rental Rules in Princeton

Princeton's short-term rental ordinance does more than add paperwork. It limits short-term rentals to your own principal residence, which changes whether buying a Princeton property to rent on a nightly basis works at all. If that was part of your plan, read this before you make an offer.

The rule that matters most

Only an owner, or a long-term lessee with a tenancy of at least six months, whose principal residence is the property may operate a short-term rental. Princeton defines principal residence as the address where you spend the majority of your non-working time, that is most clearly the center of your domestic life, and that appears on your driver's license or state ID.

Read plainly: you can rent out part or all of the home you actually live in. You cannot buy a second Princeton property purely to run as a nightly rental. Anyone modeling a Princeton purchase on short-term rental income needs to square that first, because it is the difference between a viable plan and one that ends at the permit desk.

What counts as a short-term rental

The lease of a dwelling unit, or part of one, for a term of less than 30 days. A month-to-month or longer tenancy is ordinary rental housing and is regulated separately. The 30-day line is what pulls you into this ordinance.

You need the permit before you advertise, not before the first guest arrives. Listing the property is itself the regulated act.

If you were already operating

Properties that are not a principal residence but were already running as short-term rentals get a transition window: up to 36 months from the ordinance's effective date, but only if the operator applied within 30 days of that date and the property had been actively used as a short-term rental in the prior 180 days.

That window is finite and it does not reset. If you are buying a property whose seller advertises existing short-term rental income, the relevant questions are whether that permission exists at all, how much of the 36 months is left, and whether it transfers to you. Do not assume the income continues. The ordinance is #2025-20, and your attorney should confirm the status in writing during attorney review.

Fees, inspection and what the application asks for

Registration and inspection cost $200 initially and $100 to renew each year. Permits are administered by Princeton's Office of Rental Housing Inspections and run for one year, so this is an annual obligation rather than a one-time filing. Applications are handled through the municipality's online portal, which opened January 5, 2026. Inspections must be done with the applicant present and typically take 15 to 30 minutes per unit. If your property already holds a valid rental certificate, you generally will not need a fresh inspection until that certificate expires.

The application asks for more than a name and address: owner or lessee contact details, a description of the property with a floor plan, proof that it is your principal residence (state ID, the last two years of tax returns with redactions, and three months of bank statements), a contact person reachable 24 hours a day, and proof of liability insurance of at least $500,000 for property damage and personal injury. A placard showing the maximum permitted occupancy must be posted.

Budget for the insurance line in particular. A standard homeowner's policy often will not cover nightly rental activity, and discovering that after a claim is the expensive way to learn it.

What non-compliance costs

Fines run up to $1,250 per day, and each day a violation continues counts as a separate violation. The town can also revoke the permit, and the ordinance allows for community service or imprisonment. Enforcement is not theoretical: Princeton has engaged a third-party vendor to identify unregistered short-term rentals, so an unpermitted listing is discoverable from the listing itself.

Because the penalty accrues daily, the gap between "I will get to it" and a real number closes quickly.

What this means if you are buying

For most buyers, nothing. If you are buying a home to live in and might rent a room or the whole house occasionally while you travel, you are the operator the ordinance contemplates. Register, insure, renew annually and it is a manageable cost.

For investors, the principal-residence rule is the whole story, and it is worth deciding early whether your return depends on nightly income or on ordinary long-term tenancy, which Princeton regulates separately and far more simply. Neighboring towns set their own rules, so a plan that fails in Princeton may work a few miles away. That is a conversation worth having before you are under contract rather than during attorney review.

Figures and requirements above are from the Municipality of Princeton's published short-term rental guidance and Ordinance #2025-20, as of September 2026. Municipal rules change. Confirm current fees, deadlines and your own property's status with Princeton's Office of Rental Housing Inspections, and treat this as general information rather than legal advice.
