Rent & eviction protection

Is 4506-4508 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 1924
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.

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 located at 4506-4508 California Street, owned by Paul K Wong, has undergone significant transformation since its construction in 1924. The most substantial renovation occurred in 2014, when the property underwent a comprehensive interior remodel including horizontal additions at the sides and rear, installation of a roof deck over a new fourth level, and the addition of a four-story elevator. This $750,000 project aimed to enhance living space across both units, with work completed at both ground/second levels (lower unit) and third/fourth levels (upper unit).

In addition to the major 2014 renovation, the building has seen various maintenance and compliance activities. In 2005, the rear exterior stairs were replaced, and in 1995, stucco repairs were performed on the front facade. A notable incident occurred in early 2019, when a complaint was filed regarding a potentially unauthorized third dwelling unit in the two-unit building, with concerns about short-term rental activity, though this complaint was marked as "Not Active." The property has experienced typical urban neighborhood challenges, as evidenced by several 311 calls between 2018-2022 related to street cleaning, parking enforcement, and illegal postings, though these issues appear to be street-related rather than building-specific.

Risk rating

How 4506-4508 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
71stpercentile

Out of 660 buildings in this neighborhood, 191 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
