Rent & eviction protection

Is 6337-6343 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.

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 1910
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 property at 6337-6343 California Street is a two-story multi-family residential building located in the Central Richmond neighborhood, containing four units and constructed in 1910. The building has undergone several significant renovations over the years, with the most recent notable work in 2016 including kitchen cabinet installations and electrical updates. A concerning pattern of water-related issues has emerged in recent years, with multiple water leak complaints documented in 2024, including incidents that required responses from both the Water and Public Works departments. This follows a previous water leakage problem reported in all four garages in 2018, suggesting persistent moisture management challenges. The building underwent major improvements in the late 2000s, including substantial exterior work in 2008 to address water leaks and interior renovations in 2007 that included kitchen and bathroom remodels. Historical records show the building received a vertical extension in 1987 and underwent underpinning work in 1999 due to adjacent construction. Several permits for various improvements and repairs have been properly completed, though there was at least one complaint in 2016 regarding construction allegedly conducted without proper permits. Recent municipal service calls have primarily addressed maintenance and compliance matters, including street cleaning and waste management issues in the surrounding area, though these do not directly reflect on the building's condition. The property management has generally completed required repairs and improvements as per permit requirements, but the recurring water-related issues noted in recent years may indicate an ongoing maintenance challenge.

Risk rating

How 6337-6343 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
25thpercentile

Out of 2250 buildings in this neighborhood, 1688 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

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.
