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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
48th percentile

Out of 23 buildings in this neighborhood, 12 are predicted to be safer.

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.

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.

12-Month severity forecast
No violation 52.6%
Moderate concern 33.5%
Severe concern 13.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
