Initial analysis

The two-unit residential building at 511-513 Green Street in Telegraph Hill, owned by Wong Yan Lai Kuen Revoc Liv, was constructed in 1916 and includes both flat and store components. The property has undergone several significant improvements over the years, with the most recent work being the installation of a handicap door opener completed in May 2024 and a reroofing project completed in 2021 at a cost of $15,880. The building has experienced recurring fire safety issues, with violations for blocked exits and sprinkler system concerns in April 2023, and previous violations related to alarm systems and combustible materials dating back to 2015 and 2022 respectively. A notable complaint filed in May 2023 alleged multiple code violations including an illegal dwelling in the basement, unauthorized food service, and unauthorized alcohol sales, with the status currently listed as not active but marked as "Pending Closure" in planning records.

The property has a history of accessibility improvements, including work completed in 2019 to comply with Ordinance 51-16, which involved installing a power door operator, signage, and replacing door hardware. Multiple fire safety inspections have been conducted over the years, with violations for sprinkler system maintenance, alarm system upkeep, and door hardware concerns, though most have been abated. Recent 311 calls from 2024 indicate ongoing issues with the immediate vicinity of the building, particularly regarding sidewalk cleanliness and waste management, with multiple reports of garbage, debris, and human waste being documented and subsequently resolved. The building's maintenance history shows regular attention to infrastructure needs, including earlier renovations in the 1980s for kitchen and bathroom remodeling, though more recent inspections have revealed various safety compliance issues that have required correction.

Risk rating

How 511-513 Green 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.
