Initial analysis

The 5-unit, 2-story multi-family residential building at 1491 8th Avenue in the Inner Sunset, owned by Zhou & Zheng Family Trust, was constructed in 1972 and has undergone several significant maintenance and compliance events over its history. Most recently, the building underwent a reroofing project completed in 2020 at a cost of $16,000. The property faced multiple compliance issues regarding the Soft Story Retrofit Program, with violations filed in 2014 and 2017 for not submitting required documentation, though these were subsequently resolved. A concerning plumbing and fire safety issue was documented in 2013, noting unauthorized gas line installations penetrating fire-rated walls, though this was abated by March 2017.

The building has a history of various violations and complaints, particularly in the early 2000s. A 2002 routine inspection revealed multiple fire safety concerns, including the storage of combustible materials in the garage and uncharged fire extinguishers, though these were resolved by May 2002. In 2011-2012, the property underwent unpermitted bathroom and kitchen remodeling work that raised safety concerns, including inadequate ventilation and dust control during countertop work in enclosed common areas. Security issues were noted in 2011 with reports of an insecure front door and vehicle vandalism. The building's maintenance record shows regular attention to major systems, including reroofing work in 1997 and 2020. Recent 311 calls from 2024 indicate ongoing parking challenges in the area, with multiple complaints about driveway blocking and sidewalk parking, though these are external to the building itself. The property has received routine housing inspections over the years, including records from 1999, 2002, 2010, and 2011, which have all been marked as resolved. Two planning records indicate the legalization of the 5th unit and variances granted for density, usable open space, and lot coverage issues.

Risk rating

How 1491 8Th 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
