Rent & eviction protection

Is 6217-6219 California 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 1909
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.

Built 1909
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 6217-6219 California Street in San Francisco's Central Richmond neighborhood is a two-story flats and duplex structure built in 1909, currently owned by Connie Y Ng and Almen Kwo. The property has undergone several significant infrastructure improvements over the years, with the most recent being a complete sewer pipe replacement in May 2018 and earlier work including an electrical upgrade to 150-amp service completed in 2009. The building previously experienced multiple sewer-related issues between 2015 and 2018, with seven documented sewage backup incidents through PUC Sewer Operations, though these appear to have been resolved through proper attention to the system. Other notable improvements include a reroofing project from 2005 (now expired) and the installation of fourteen aluminum windows in 1984.

The property's maintenance history shows regular attention to infrastructure needs, though some recent surface issues have been documented through 311 calls, including instances of glass hazards (2021), an overflowing city garbage can (2020), and sidewalk parking violations (2023). Of particular note is the building's age and corresponding plumbing history; while the recent sewer pipe replacement in 2018 represents a significant upgrade, the previous pattern of sewage backup incidents suggests this system required particular attention. The building's overall permit and maintenance history indicates a pattern of addressing major systems (electrical, plumbing, roofing) as needed, though some permits are now inactive or expired. The property appears to have experienced typical urban maintenance challenges associated with its location, particularly concerning street-level issues that have been addressed through city services.

Risk rating

How 6217-6219 California 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
39thpercentile

Out of 2250 buildings in this neighborhood, 1372 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
