Lake Street, SF 94118 1366024 6 units · 3 fl · 1924

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 4430-4432 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.

Built 1924
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 3-story, 6-unit multi-family residential building at 4430-4432 California Street, constructed in 1924 and owned by Doris Wong, has undergone several significant renovations and faced multiple regulatory challenges over the past decade. The most recent major work occurred in 2011, when extensive renovations were completed on the 2nd floor rear unit, including kitchen relocation, bathroom remodeling, and electrical improvements totaling over $52,000. This renovation was part of a series of correctional measures addressing violations from 2010, which included removing illegal windows along property lines, addressing fire safety concerns, and compliance with building codes. The building has experienced periodic routine inspections since 2000, with several violations noted and subsequently resolved, including issues with backflow prevention, fire safety systems, and unauthorized modifications.

More recent concerns have been relatively minor and generally external to the building itself, with 311 reports showing typical urban maintenance issues such as street cleaning, garbage, and graffiti complaints between 2019 and 2025. There was one fire-related incident involving a malfunctioning alarm system, but no injuries were reported. The property has undergone multiple unit renovations over the years, including window replacements in 2009 and various kitchen and bathroom remodels, with proper permits obtained in recent projects including plumbing and electrical work. While there have been several building code violations and complaints, records indicate that these issues have typically been addressed and resolved through appropriate permits and corrections.

Risk rating

How 4430-4432 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
17thpercentile

Out of 660 buildings in this neighborhood, 548 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 size

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
