Rent & eviction protection

Is 347-349 10Th 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

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 property at 347-349 10th Street in San Francisco's South of Market neighborhood is a two-story, Class A historic resource multi-family residential building constructed in 1908, currently owned by Liang Xianhui. The building is undergoing significant proposed changes, with approved permits from December 2022 for a substantial renovation project valued at $1.8 million that includes a 14-foot horizontal addition, vertical extension to add a new 5-bedroom townhouse unit, seismic upgrades, fire sprinklers installation, and egress improvements. This follows earlier permits filed in June 2019 proposing to demolish the existing duplex and replace it with a 5-story multi-family dwelling, though these permits were later withdrawn in favor of the current approved plans.

The building has a mixed maintenance and violation history, with notable events including multiple unauthorized short-term rental violations that were eventually abated, and various maintenance and improvement projects over the years. These include plumbing repairs completed in 2008, electrical upgrades in 2005, and basement modifications for exercise space in 2005. Recent 311 calls from 2024 have primarily related to street-level issues such as garbage, debris, and graffiti, though most of these were resolved without requiring significant action. A notable historical aspect of the building's recent past is a July 2019 fire complaint that was determined to have no merit, and there are no recorded tenant buyouts associated with this address.

Risk rating

How 347-349 10Th 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
65thpercentile

Out of 430 buildings in this neighborhood, 150 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.

Property class: single-family home

Single-family homes (class A) have distinct violation and complaint patterns from multi-family buildings.
