Rent & eviction protection

Is 1243-1247 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 1908
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 1908
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-unit multi-family residential building at 1243-1247 Jackson Street in Nob Hill, owned by the Sharon L Wong 2009 Trust, is a three-story structure constructed in 1908. The property has undergone several significant improvements over the past decade, with the most recent being a comprehensive window replacement project in 2022 that installed 20 new wood windows (15 in the front, 5 in the back) meeting latest energy efficiency standards with a U-factor not to exceed 0.30. Between 2021-2022, substantial interior upgrades were completed across all three units, including bathroom renovations, electrical improvements with new recessed lighting, plumbing updates with new fixtures, and the installation of modern bathroom ventilation systems. A notable infrastructure upgrade occurred in 2010 when the electrical service was enhanced from 100-amp to 200-amp with new meters and sub-panels.

The building has undergone regular routine inspections by Housing Inspection Services in 1999, 2001, 2009, and 2016, with all violations from the 2009 inspection being promptly addressed and abated by March 31, 2009. These violations included safety-related issues such as water heater elevation requirements, fire extinguisher installation, and gate self-closing mechanisms, all of which were resolved within three weeks. The property experienced a sanitary sewer vent issue in March 2022, which was promptly addressed, along with recurrent sidewalk cleaning needs noted in 2019-2024, suggesting regular maintenance requirements typical for the neighborhood. The building's recent renovation history demonstrates ongoing maintenance and upgrading of the property, particularly focusing on energy efficiency and modernizing essential systems, while historical compliance issues from 2009 have been fully resolved.

Risk rating

How 1243-1247 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
88thpercentile

Out of 1125 buildings in this neighborhood, 135 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.

Neighborhood (ZIP code)

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

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.
