Multifamily and Duplex Properties for Sale in Berkeley: Zoning and Rent Rules

What multifamily in Berkeley looks like

Berkeley has some of the oldest and most regulated rental housing in California. Brown-shingle and Victorian houses split into flats fill North and South Berkeley. Stucco "dingbat" apartments from the 1950s and 1960s, many with parking under the building, line the flats near campus and downtown. Newer mixed-use buildings rise downtown and along the avenues. Student demand from UC Berkeley drives the Southside, where group living and rooms rented separately are common. Most buildings built before mid-1980 are under full rent control, so the rent roll matters more than almost anywhere. For financing, see financing 2-4 unit properties and apartment building loans.

Where the zoning allows it

Residential districts are in Chapter 23.202. The table summarizes district figures from the GoCodebook overview; confirm against the code tables.

Middle housing. The city’s middle housing page says the City Council adopted new rules in July 2025, effective November 1, 2025. They allow two to six units, from duplexes to courtyard apartments, in R-1, R-2, R-2A and MU-R outside the high fire hazard areas of the hills. Projects that meet objective standards get a ministerial certificate within 30 days, with no appeal to the Zoning Adjustments Board or Council. The standards cap height at 35 feet with no exceptions and lot coverage at 60%, and require front and rear setbacks totaling at least 20 feet, with at least 5 feet in each. The city’s announcement says fees run 50% to 75% below the old permits. Demolished units must be replaced one for one, and existing tenants have rights to comparable units. See our SB 9 lot split guide and ADU investment guide.

Rent rules: local rent stabilization

Berkeley’s Rent Stabilization and Eviction for Good Cause Ordinance (Chapter 13.76) is run by the Rent Board.

• Coverage. The Board’s registration page says fully covered units include most multifamily units built before June 1980, single-family homes with tenancies from before 1996, and houses with five or more rooms rented separately. Partially covered units, including newer buildings, most single-family homes and most condos, are exempt from rent ceilings but remain under good cause and deposit interest rules.
• Annual General Adjustment. The AGA is 65% of the Bay Area CPI change, capped at 5%, and takes effect each January 1. The Board set the 2027 AGA at 2.5%. The Attorney General’s chart lists 1% for 2026 and notes that no increase is allowed in a tenancy’s first two years. The AGA is barred if registration fees are unpaid, deposit interest is owed or serious code problems exist. Unused AGAs can be banked.
• Good cause. Section 13.76.130 lists 11 grounds for ending a tenancy, and copies of notices must be filed with the Rent Board within 10 days.
• Owner move-in. Relocation is $15,000 for households with at least a one-year tenancy, plus $5,000 for low-income, senior (60+), disabled or child households or tenancies from before 1999. Both figures rise with CPI each January 1, and the standard amount goes into city escrow within 10 days of notice. Tenants 60 or older or disabled with five or more years in place are generally protected from owner move-in. So are families with a minor child during the school year.

Partially covered units may fall under the state cap. For Alameda County that is 8.8% for increases from August 1, 2026. See our AB 1482 guide and just cause eviction guide.

Berkeley rental property rules

• Registration. Most units must be registered with the Rent Registry. FY 2026–27 fees were due July 2, 2026, and the ordinance adds a 100% penalty for late payment.
• Withdrawals. Withdrawing units under the Ellis Act requires 120 days’ notice, or one year for tenants 62 or older or disabled with a year of tenancy, according to the GoCodebook rental summary.
• Buyouts. Buyout offers on controlled units need a written disclosure, and tenants have 30 days to rescind; Chapter 13.79 covers buyout agreements.
• Short-term rentals are regulated under Chapter 23.314.

Soft-story retrofits and older buildings

Berkeley’s soft-story ordinance, Chapter 19.39, makes retrofits mandatory for wood-frame buildings of five or more units with weak ground floors such as tuck-under parking or storefronts. Owners must hire an engineer to evaluate the building and then retrofit to the adopted standard. The findings note that a 1996 survey counted nearly 400 such buildings and that buildings put up after January 1, 1978 are treated as meeting acceptable standards. Before buying a pre-1978 apartment building over parking, get the city’s compliance record. See our seismic retrofit guide and SB 721 balcony inspections.

Underwriting a Berkeley multifamily purchase

1. Get the Rent Board record for every unit: coverage, registered rent ceiling, banked AGAs and fee status.
2. Model increases at the AGA (2.5% for 2027), not market rent, for fully covered units.
3. Price owner move-in or Ellis exposure using the CPI-adjusted relocation amounts and protected-tenant rules.
4. Check soft-story compliance for five-plus unit buildings with open ground floors.
5. For a lot in R-1, R-2, R-2A or MU-R, test middle housing potential against the 35 ft, 60% coverage and setback standards.
6. Get estoppel certificates and add the city transfer tax ($15 per $1,000 to $1.7 million, $25 above, per the County Clerk-Recorder) to our rental property analysis.
