Rent & eviction protection

Is 836-840 Waller 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 1962
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 1962
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 836-840 Waller Street is a 15-unit, 3-story multi-family residential building constructed in 1962, currently owned by Kong Siuling. The building has undergone several significant maintenance and improvement projects over the past two decades, with the most recent being a complete electrical system upgrade in 2024, including the replacement and relocation of the main meter and panel for all 15 units. In 2015-2016, the building underwent various structural and safety improvements, including the replacement of wood railings with metal railings and termite-related repairs. The building has experienced recurring issues with unpermitted construction work and dust mitigation, most notably in 2014 and 2015, though these complaints were eventually resolved. Fire safety systems have required periodic attention, with sprinkler system issues noted and corrected in both 2021 and 2017.

Recent inspections and violations from September 2023 required the building to submit various compliance affidavits, which were abated by October 2023. The property has maintained an active maintenance schedule, with regular updates to individual units including kitchen and bathroom remodels in units #4 and #12 in 2009, and various plumbing and electrical upgrades throughout the building. External maintenance has included addressing graffiti issues, with documented cases in 2022-2023, and there have been several street cleaning requests in 2023. The building's history shows consistent attention to maintenance and upgrades, with particular focus on compliance with safety regulations and system modernization, though there have been occasional lapses in permit requirements that resulted in formal complaints.

Risk rating

How 836-840 Waller 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
6thpercentile

Out of 351 buildings in this neighborhood, 330 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.
