Rent & eviction protection

Is 71-73 Bernard St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built before 1979
Built 1933

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The two-unit residential building at 71-73 Bernard Street in Nob Hill, owned by Cheung Family Trust, is a two-story flats and duplex structure built in 1933. The property has experienced several significant events, most notably a vehicular accident in March 2019 when a car collided with the front of the building, causing damage to the west side front wall approximately 6 feet wide by 10 feet tall, with both stucco façade and structural components affected. This incident required repair work that was completed by August 2019, with associated costs of $9,500. The building underwent exterior improvements in 2017 with the installation of vinyl siding on the back of the house, costing $16,567. More recently, essential infrastructure work was completed in May 2024 with the replacement of the house trap and approximately 20 feet of sewer line.

The property has experienced various maintenance and infrastructure issues over the years, including a sewage backup incident in February 2021 and three consecutive months of sidewalk cleaning necessitated by waste removal from September to November 2019. The building has undergone several other improvements, including aluminum window installation in 1985 (permit expired) and multiple street cleaning requests in early 2020. Two fire incidents have been recorded: one involving building fire with unintentional ignition (date unspecified) and another detector activation with no fire (also unspecified), neither resulting in civilian injuries. Recently, in late 2023 and early 2025, there have been administrative matters related to rent board services and encampment removal, respectively, though these do not directly pertain to the building's condition or safety.

Risk rating

How 71-73 Bernard St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
97thpercentile

Out of 1125 buildings in this neighborhood, 34 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
