Rent & eviction protection

Is 159 Clara 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 1906
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 1906
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 3-unit, 2-story multi-family residential building at 159 Clara St, owned by the Woo Family Trust 1990, has a documented history of maintenance and safety concerns dating back to its 1906 construction. Most recently, in September 2024, multiple repairs were undertaken, including replacement of the front wooden gate and stairs railing, as well as repairs to wooden steps, suggesting ongoing maintenance of access infrastructure. However, a building complaint was filed in August 2024 regarding unpermitted work and early morning construction activity in the rear building, which was addressed by September 2024. More seriously, between 2023-2024, the building experienced multiple fire code violations, including issues with the sprinkler/standpipe systems, for which violations were issued in July 2024, and multiple violations in May 2023 regarding fire extinguishers, electrical conditions, and general permit requirements. The building has also faced structural concerns, with a February 2020 complaint reporting leaning structure and unsafe living conditions, though this complaint's current status is not indicated. A series of 311 calls in early 2025 primarily relate to external encampments and garbage issues in the surrounding area, rather than directly involving the building itself.

The property's maintenance history shows attention to stairway safety, with repairs documented in 2002, 2024, and ongoing work as of September 2024. The building has experienced some basic safety incidents requiring fire department response, though none resulted in civilian injuries. Notably, there have been no recorded fire incidents involving actual fires, with most responses relating to false alarms, elevator rescues, and system checks. The property has maintained an active permit record, with recent work being conducted under proper permits, though the August 2024 complaint suggests potential concerns about strict compliance with permit requirements. The building's geographic location appears to face external challenges as evidenced by the numerous 311 calls regarding encampments and street cleaning needs in the vicinity during 2025, though these external issues do not directly reflect on the building's internal conditions or management.

Risk rating

How 159 Clara 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
47thpercentile

Out of 23 buildings in this neighborhood, 12 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Building age

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

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.
