Rent & eviction protection

Is 4162-4164 26Th 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 1900

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 1900
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 4162-4164 26th Street in Noe Valley is a four-story, three-unit multi-family residential building constructed in 1900, currently owned by Tony Szeto and Annie T F Kong. The building underwent significant safety and infrastructure upgrades between 2016-2018, including the installation of a comprehensive fire sprinkler system throughout the building with 62 sprinklers, electrical system upgrades with 200-amp service and four meters, and the installation of new furnaces for all units. However, there are several notable concerns in the building's history. Most significantly, there are active violations from 2012 related to unauthorized excavation work in the crawl space and issues with a rear porch structure, which were referred to Code Enforcement Division. There were also multiple complaints in 2017 regarding unauthorized removal of property boundaries and fencing, and a 2013 complaint about potentially unsafe excavation work. The building's basement conversion and additional construction work has been the subject of various permits and planning records, including attempts to legalize basement unit conversion.

Recent maintenance and safety checks have shown improvements, with the 2022-2023 period showing primarily routine parking enforcement matters, though there was a fire complaint in 2022 regarding weeds and grass that was corrected by March 2023. Street space permits were issued multiple times between 2016-2018, suggesting some exterior work or temporary usage changes. The building's systems were significantly modernized during the 2016-2018 period, with improvements to plumbing, electrical, and fire safety systems, though some permits from this period are noted as expired. The property's recent history (post-2018) has been relatively stable, with no major new compliance issues reported, though there remains some uncertainty regarding the final status of the 2012 excavation violations, as they appear as active cases in the records.

Risk rating

How 4162-4164 26Th 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
24thpercentile

Out of 1879 buildings in this neighborhood, 1428 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 floors

Building height affects maintenance complexity and is one of the size signals the model uses.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Building size

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