Lower Pacific Heights, SF 94115 0651020 11 units · 2 fl · 1900

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 2159 California 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 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.

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

2159 California Street is a two-story, 11-unit multi-family residential building constructed in 1900, currently owned by Ronald B. Koo. The property has undergone significant recent improvements, with substantial renovation work completed in 2021 including kitchen and bathroom remodels in units 1A, 1B, 2, and 3, as well as the installation of a new laundry room on the third floor, representing a focused effort to modernize the building's amenities. The building went through multiple structural and systems upgrades between 2017-2019, including electrical rewiring, plumbing improvements, and the installation of a 200-amp 3-phase underground service. While the building appears to be currently in good condition, there are historical records of fire safety violations in 2019 related to alarm systems and sprinkler maintenance, both of which were subsequently corrected. The property is classified as Tier 3 in soft-story retrofitting status, indicating that required seismic upgrades have been completed.

The building's history includes several tenant buyouts in 2016 totaling $132,500, suggesting significant turnover in the past. Recent 311 calls from 2020-2023 have primarily concerned street cleaning issues, with no reports indicating building-specific problems. Historical complaints include routine safety inspections in 1996 and 2013, as well as a 2003 plumbing-related issue, all of which have been resolved. The most recent fire alarm complaint in February 2024 was determined to have no merit, indicating ongoing attention to safety systems. The building's permits and improvement records demonstrate consistent maintenance and upgrading of essential systems, though potential residents should be aware of its age and historical context as a 123-year-old structure.

Risk rating

How 2159 California 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
15thpercentile

Out of 670 buildings in this neighborhood, 570 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.

Building age

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