Initial analysis

110 Portola Drive is a 7-unit, 3-story multi-family residential building constructed in 1976 and currently owned by the Larkin Family Trust. The property has undergone several significant improvements over the past decade, most notably completing a seismic soft-story retrofit in 2015 as required for Tier 3 buildings, with work valued at $18,000. In 2018-2019, the building received substantial exterior upgrades including new James Hardie 7" lap siding ($18,000) and window replacements on the front and north side ($15,000). The building's maintenance record shows regular attention to structural and safety requirements, with a gas fireplace inspection completed in 2023.

The building experienced multiple fire and sanitation-related violations in 2003, including issues with egress obstructions, handrails, and combustible storage, though all were abated by November 2003. More recent building complaints have been minimal, with the last routine housing inspection occurring in 2011. The property has had occasional exterior maintenance issues as documented in 311 calls, including reports of graffiti and loose garbage on the sidewalk, though these have been documented as resolved. Two emergency incidents were recorded at the address, one related to a carbon monoxide detector activation (which was a false alarm) and another emergency medical incident, neither resulting in civilian injuries.

Risk rating

How 110 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
52th percentile

Out of 172 buildings in this neighborhood, 83 are predicted to be safer.
