Initial analysis

The two-unit residential building at 34 Castro Street, located in the Buena Vista Park neighborhood, is a two-story flats and duplex structure built in 1906 and currently owned by Louise Swig. The property has undergone several significant improvements over the years, with the most recent major works including a plumbing upgrade in 2013 involving the replacement of approximately 25 feet of waste pipes, and multiple instances of graffiti requiring attention between 2022 and 2024. Historical records show substantial renovations in 2007, including a kitchen remodel with new cabinets, sink, faucet, lighting, and repainting, along with electrical improvements to the lighting system, and reroofing work that same year. Notably, there was a serious roofing issue reported in November 2002 that resulted in water damage affecting the first floor ceiling in a bar area, though this issue was promptly resolved within four days.

Earlier renovation attempts are documented from 1990, including expired permits for kitchen and bathroom remodeling and construction of rear yard masonry fences, though these permits were later renewed. The property has experienced recurring issues with graffiti in recent years, with four documented incidents between 2023 and 2024, and there have been occasional reports of encampments and parking violations in the vicinity, which were resolved by authorities. A damaged tree incident was reported and resolved in January 2020. While the building's maintenance history shows regular upkeep through various permits and repairs, the pattern of graffiti incidents in recent years and the notable roof leak incident from 2002 are the most significant points of concern in the building's record.

Risk rating

How 34 Castro 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.
