A sale doesn't end the tenancy
The Berkeley Rent Board is blunt about it: a sale, a foreclosure or any other change in ownership isn't a just cause for eviction. In most cases the terms of the tenancy, rent included, carry straight over to the new owner. That holds whether the buyer is a family who wants to live there or an investor.
What a buyer is really pricing is the tenancy you hand over: which rules cover the unit, whether its Rent Board record is clean, and what it would cost to get the house back if they ever wanted to live there.
Fully covered or partially covered?
Most Berkeley rentals sit in one of two groups, and which one changes what the house is worth to a buyer.
- Fully covered units have rent control, good-cause eviction and interest on security deposits. That's most units in multi-family buildings built before June 1980, single-family homes where the current tenancy began before 1996, and single-family homes with five or more rooms rented on separate leases.
- Partially covered units have no rent ceiling, but good-cause eviction and the deposit interest rules still apply. That's most single-family homes and condos, plus new construction with a certificate of occupancy issued after 1980.
You can look the unit up in the Rent Board's online Rent Registry or call its Registration Unit at (510) 981-7368, ext. 2.
Clean up the registration before you sell
This is where sellers lose money at closing without seeing it coming. Most Berkeley rentals have to be registered, with a fee every year. The 2026–27 fee was due July 2, 2026, and the ordinance adds a 100% penalty to late payments.
Those debts don't stay behind when you sell. The Rent Board says new owners are responsible for the prior owner's unpaid registration fees and penalties, so a buyer who checks will want the balance paid in escrow or taken off the price. Paying it before you list is simpler.
Measure BB, which Berkeley voters passed in November 2024, tightened this further. Owners of partially covered units now have to report a new tenancy to the Rent Board within 15 days of its start, and the Board can fine owners who let registration lapse.
Showings and estoppels
State law lets you go in to show the house to buyers, but you have to give the tenant written notice, with 24 hours presumed reasonable, and come during normal business hours (Civil Code §1954). The tenant doesn't have to be home.
The Rent Board also suggests tenant estoppels: a short signed statement from the tenant confirming the rent, the deposit, any open repair requests and any side agreements, with the lease attached. Buyers lean on them, and they keep surprises out of escrow.
If the buyer wants to move in
A buyer who plans to live there has to follow Berkeley's owner move-in rules, which cover single-family homes and condos too. With the 2026 figures:
- The owner has to hold at least 50% of the property, move in within three months, and then live there for 36 months straight.
- A tenant household that has lived there at least a year gets a relocation payment of $19,413, deposited with the Rent Board within 10 days of the notice. Low-income, elderly or disabled tenants, households with children under 18, and tenancies that started before January 1, 1999 can be owed another $6,471.
- A household with minor children can't be evicted this way if the notice runs out while the Berkeley school year is in session.
- The tenant keeps the right to move back in whenever the owner moves out, with no time limit.
That cost and that wait are a big part of why a rented Berkeley house usually sells for less than the same house empty, and why plenty of buyers of occupied houses simply keep the tenant.
Buyouts and the Ellis Act
Some owners offer the tenant a voluntary buyout before selling. Others take the whole property off the rental market under the state Ellis Act, which in Berkeley comes with its own notice periods and payments. The Rent Board recommends talking to them or a landlord-tenant attorney before you make an offer to the tenant or send any notice.
Selling it with the tenant in place
A cash buyer can buy the house occupied. That means one walkthrough instead of weeks of showings, the lease taken over at closing, and the tenancy handled by the new owner afterwards under Berkeley's rules. To get a solid offer, have these ready:
- The signed lease, or the agreed terms written down if it was a handshake deal
- What the tenant pays now, how big the deposit is, and whether they're behind
- The unit's Rent Registry record and a receipt for this year's registration fee
- Copies of any notices either side has served, plus repair requests still open
