Rent & eviction protection

Is 1270 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 1914
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 7-unit, 3-story multi-family residential building at 1270 California Street in Nob Hill, owned by Jennifer Tong, has undergone several significant safety and infrastructure improvements since its construction in 1914. Most notably, the building completed a comprehensive fire alarm system upgrade in 2023-2024, including the installation of low-frequency sounders in all sleeping areas to comply with current fire safety codes, with the work totaling over $38,000. The building successfully completed its mandatory soft-story retrofit in 2014 (Classified as Tier 3) at a cost of $65,000, addressing seismic safety requirements. Other major improvements include a window replacement project in 2012 ($20,000) improving energy efficiency and safety compliance, and a reroofing project in 2007 ($17,800).

The building has had multiple routine inspections and one health and safety inspection in 2010, which identified several violations that were subsequently resolved, including issues with fire escape maintenance, self-closing doors, and smoke enclosure systems. While these violations were addressed, they indicate historical concerns with the building's safety systems. More recent building activity has focused on upgrading safety systems rather than addressing major structural issues. The property experienced a tenant buyout involving 4 tenants in March 2016. Recent 311 calls (from 2019-2024) primarily concern street cleaning and parking issues on or near the property, rather than building-specific problems.

Risk rating

How 1270 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
29thpercentile

Out of 1125 buildings in this neighborhood, 799 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.

Neighborhood location

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