Rent & eviction protection

Is 27-29 Stone 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 1965
2 or more units

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.

15+ years since occupancy
Built 1965
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 three-story multi-family residential building at 27-29 Stone Street in Nob Hill, owned by Sung Kai-min E & Sung Conni, consists of two units and was constructed in 1965. The property has undergone significant renovations in 2019, with Unit #27 receiving a $40,000 rehabilitation of the kitchen and bathroom, along with washer and dryer installations, and Unit #29 undergoing an $80,000 transformation including the addition of a bedroom and bathroom on the fourth floor, bathroom rehabilitations, washer and dryer installations, and sliding door replacements. Both units received comprehensive updates to their electrical systems and plumbing infrastructure, including new electrical fixtures such as lights, switches, and smoke detectors in Unit #29, and heating system repairs in November 2019. The building's maintenance history shows attention to structural needs, with re-roofing work initiated in 2017, while records from 2023-2024 indicate ongoing challenges with street-level debris and illegal parking issues in the vicinity.

The property's maintenance and improvement record demonstrates substantial investment in unit modernization and infrastructure maintenance, particularly during 2019 when most major works were completed. A recent planning application for Unit #29 was approved for window and door modifications on the fourth floor, maintaining the building's character while updating its features. While there have been some quality-of-life complaints in the surrounding area, such as noise during garbage collection and instances of abandoned debris, these appear to be primarily street-level issues rather than building-specific concerns. The building's permits and maintenance records suggest regular upkeep and modernization efforts by the owners, with no reported safety violations or structural issues in recent years, and all major renovation permits have been properly completed.

Risk rating

How 27-29 Stone 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
98thpercentile

Out of 1125 buildings in this neighborhood, 22 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
