Your Lease Doesn't End Because the Building Changed Hands
A lease is a binding contract, and selling the property doesn't cancel it. The new owner takes the property subject to your lease and has to honor its terms for the rest of your lease period — the rent amount, the end date, maintenance obligations, and everything else you agreed to. This is a basic principle of property law, not something that depends on the new owner agreeing to it.
What Happens to Your Security Deposit
When ownership changes, the outgoing landlord generally has to either transfer your deposit, minus any lawful deductions already made, to the new owner, or return it directly to you — doing one of the two relieves them of further responsibility for it. California's deposit statute spells this out directly: on a sale, the landlord must transfer the remaining deposit to the successor and notify the tenant of the transfer, or return it to the tenant, and a successor who doesn't comply can be held jointly liable with the seller for repaying it (Cal. Civ. Code § 1950.5(i), (k)). Other states handle the mechanics differently, though the underlying idea is the same: your deposit doesn't just disappear because the building changed hands. If you're not told where your deposit went, follow up in writing and ask.
What Can Change, and What Can't
The lease terms themselves can't change without your agreement, but plenty of administrative details can: where you send rent, who handles maintenance requests, the property manager, and building policies that aren't part of your lease. California requires an owner or successor owner to disclose who's authorized to manage the property and where to send rent within 15 days of taking over, and bars evicting a tenant for unpaid rent that accrued while the new owner was out of compliance with that disclosure (Cal. Civ. Code § 1962). Even where a similar rule isn't on the books in your state, get this information in writing before you send your next rent payment to a new party you haven't verified.
Month-to-Month Tenancies Are More Exposed
If you're renting month-to-month rather than under a fixed lease, a new owner has more flexibility than they would with a fixed-term tenant. They generally still have to honor the current terms and give you proper advance notice before making changes — including ending the tenancy — the same as any landlord would, but a month-to-month arrangement gives less protection against a new owner who wants to reposition the building or raise rents, since there's no locked-in end date standing between you and a properly noticed change.
A Concrete Example
Say you're eight months into a 12-month lease at $1,400 a month when the building sells. The new owner can't tell you your rent is now $1,700 starting next month, can't shorten your lease term, and can't change your maintenance responsibilities — all of that carries over exactly as you signed it, for the remaining four months. What the new owner can do is take over collecting your rent, handling repair requests, and eventually deciding whether to offer you a renewal at a different rate once your current term actually ends. The distinction that matters is between changing your existing agreement, which they generally can't do, and controlling what happens after it expires, which they generally can.
Steps to Take When You Learn of a Sale
Keep a copy of your signed lease somewhere you can access it independent of the building's files. Request written confirmation of the new owner's or manager's contact information and where rent should go, and don't just start paying a new party because someone told you to over the phone. If your deposit isn't accounted for within a reasonable time, ask for it in writing, citing your original deposit receipt if you have one.
If Something Looks Off
A sale is also a common moment for problems to slip through — a deposit that never gets transferred, a lease term someone claims doesn't apply anymore, or a new party asking you to sign something you never agreed to as a condition of "updating" your file. You're not obligated to sign a new lease, a new deposit agreement, or anything else just because ownership changed; your existing lease keeps governing until its own term ends unless you voluntarily agree to something different. If a new owner or manager pressures you to sign quickly, ask for time to read it and compare it against your original lease before you do. Honestkey can review your original lease so you have a clear record of what was actually agreed to, independent of who currently owns the building.
