Initial analysis

The property at 1052-1054 Jamestown Avenue is a 3-story, 2-unit multi-family residential building located in Bayview Heights, constructed in 1925 and currently owned by Zhou Jianle. The building has a documented history of violations and compliance issues, most notably regarding an illegal basement dwelling unit. A series of violations were first documented in 2010, leading to enforcement actions through 2013, including concerns about unauthorized plumbing, electrical work, and lack of proper egress. The illegal unit was subsequently removed in 2015 at a cost of $30,000, though this work has continued to be a focus of regulatory attention. Most notably, as of January 2024, there is an active complaint regarding incomplete work related to a new rear door and deck, suggesting the scope of previously approved work (PA201709219269) has been exceeded.

The building has undergone several significant improvements and required repairs over the years. In 2017-2018, major renovations were completed including the addition of a media room, den, gym room, and half bathroom, along with the installation of new plumbing and electrical systems (work valued at $80,000). There have been multiple building systems upgrades, including a new water heater and furnace installation. The property has experienced various maintenance issues documented through housing complaints, including problems with heating, water damage, and plumbing systems between 2010 and 2013. Recent records (2024) show numerous parking enforcement actions in the vicinity of the property, with multiple citations issued for parking violations between November 2024 and January 2025, though these are external to the building's condition or safety concerns. Additionally, there have been three fire-related complaints on record (2006, 2010, 2017), though none resulted in documented violations despite varying closure dates.

Risk rating

How 1052-1054 Jamestown 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.
