Initial analysis

This two-story, four-unit multi-family residential building located at 154 Portola Drive in Twin Peaks was built in 1961 and is currently owned by the Survivor's Trust. The building has a history of significant maintenance and safety issues, most notably in 2003 when multiple fire safety violations were documented, including problems with a clothes dryer, fire extinguisher maintenance, damaged ceilings, stairs, and combustible storage. These violations were all addressed by October 9, 2003. More recent concerns arose in 2015 regarding unauthorized modifications, specifically the installation of skylights over the interior court that were reported to have blocked natural ventilation to kitchens and bathrooms in all four units, leading to violations for work without permits and lack of required ventilation in habitable rooms and bathrooms. This issue was not officially marked as resolved until August 2019, though there was a brief fire complaint in October-November 2015 regarding extinguishers and combustible materials that was addressed promptly.

The building's maintenance record includes a reroofing project from 1991, though the permit for this work has since expired. Recent external concerns have primarily involved issues in the vicinity of the building, including multiple reports of overflowing city garbage cans (2020-2023), graffiti (2022), and illegal parking (2020, 2023). While these issues have been addressed through standard municipal channels, they are generally outside the direct responsibilities of the building's management. A tree maintenance request from April 2021 remains open as of the latest data. The property has undergone routine inspections by Housing Inspection Services, with records showing compliance with correction orders where violations were found, though the duration and complexity of these issues suggest a history of maintenance challenges requiring regular oversight.

Risk rating

How 154 Portola Dr'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
85th percentile

Out of 172 buildings in this neighborhood, 26 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Building age

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

12-Month severity forecast
No violation 58.0%
Moderate concern 24.6%
Severe concern 17.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
