Initial analysis

The property at 522-524 34th Avenue in San Francisco's Outer Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1924, currently owned by Golden State Property LLC. The building has undergone several significant renovations and faced multiple infrastructure challenges in recent years. Most notably, issues with heating and electrical systems have been recurring problems, with violations for inadequate heating documented in 2019 and continuing electrical issues reported in 2020-2023. A significant complaint filed in September 2023 cited concerns about a garage conversion with ventilation issues and plumbing complications, while earlier complaints from 2020-2021 documented electrical power outages affecting multiple units. The building underwent several improvements, including a roof replacement in 2017, a first-floor unit legalization project in 2019 (cost: $80,000), and kitchen/bathroom remodels in 2022, which included extensive electrical updates.

The property has a history of maintenance challenges requiring city intervention, including an active electrical violation related to the fuse panel as of 2020, though some earlier heating violations were eventually resolved. The building's systems have been updated in recent years, with a new gas furnace installed in 2019 and significant electrical work completed in late 2024 to address a notice of violation. Historical records indicate earlier unauthorized unit conversions and modifications, including an illegal in-law unit and unpermitted kitchen conversion in 2018, though these issues were addressed through the legalization process completed in 2019. The property has also experienced plumbing challenges, including a sewage backup incident in 2021, and several sidewalk maintenance issues resulting in emergency repairs. These combined records suggest ongoing efforts to improve building systems and comply with regulatory requirements, though infrastructure challenges have persisted as a notable pattern.

Risk rating

How 522-524 34Th 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.
