Rent & eviction protection

Is 1234-1240 Jackson 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 1911
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.

15+ years since occupancy
Built 1911
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

This three-story, six-unit multi-family residential building located at 1234-1240 Jackson Street in the Nob Hill neighborhood was constructed in 1911 and is currently owned by the Kim Oi Chan Gin Trust. The property has undergone several significant improvements over the past two decades, most notably completing a mandatory soft-story retrofit in 2017 at a cost of $80,000 to enhance seismic safety. The building has maintained compliance with housing inspections, with routine inspections occurring in 2000, 2003, 2008, and 2016, showing generally proactive management oversight. Historical records indicate a series of electrical upgrades in 2003-2004 to address violations, including the installation of new lighting, switches, and receptacles throughout the building and basement areas, as well as addressing plumbing and fire safety concerns.

The property has experienced various maintenance and regulatory challenges, particularly during the early 2000s, including a cluster of building code violations in 2000 related to fire safety, plumbing, electrical systems, and stairs that were all addressed and abated by September 2003. A significant interior remodeling project occurred in 2003 involving the removal of kitchen and bathroom fixtures, and previous exterior work included stucco replacement in 2000. More recent history shows relatively few major issues, with recent 311 calls in 2023-2024 primarily concerning external matters such as sidewalk graffiti, noise complaints, and parking issues. The building's fire safety systems appear to be in order, with only one minor CO detector activation incident reported (due to malfunction, with no injuries). While there are some open 311 calls from 2023-2024 regarding sidewalk graffiti and noise, these do not directly reflect on the building's condition or management.

Risk rating

How 1234-1240 Jackson 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
45thpercentile

Out of 1125 buildings in this neighborhood, 619 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.

Number of units

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.
