Initial analysis

The 5-unit residential building at 87-93 Lupine Avenue, owned by the Ng Family Trust, is a two-story apartment building constructed in 1950 in the Jordan Park/Laurel Heights neighborhood. The property has undergone several significant renovations, with the most substantial work occurring in 2017 when three units (301, 504, and 501) received bathroom and kitchen remodels with electrical and plumbing updates, each with a permitted cost of $35,000. Other notable improvements include a 2014 bathroom renovation in one unit valued at $13,400, reroofing work completed in 1999, and code compliance upgrades in 1986.

The building has experienced some safety-related issues in the past, particularly during a 2004 routine inspection that identified concerns with wooden stairs, smoke detectors, and emergency exits, which were subsequently addressed by June 2004. A 2011 fire safety violation regarding combustible storage or sprinkler requirements was also resolved. More recent concerns have centered around outside conditions, with multiple 311 calls in 2024 reporting issues such as garbage and debris, though these were not directly related to the building's internal conditions. The property has had several fire alarm activations, all of which were determined to be unintentional with no injuries reported, including six smoke detector activations and one incident involving an overheated motor. While there was one fire complaint in 2011, it was found to have no merit. The building's recent history (2023-2024) shows more focus on external cleanliness and encampment-related issues in the vicinity rather than internal structural or safety concerns, with the most recent building-related permits expiring in 2017 for plumbing and electrical work.

Risk rating

How 87-93 Lupine Ave'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

Out of 272 buildings in this neighborhood, 171 are predicted to be safer.
