Initial analysis

The three-story multi-family residential building at 519-521 Valencia Street in the Inner Mission, owned by Rsr Valencia Properties Llc, was constructed in 1906 and contains 3 units with ground-floor commercial space. The building has experienced several significant electrical and safety issues over the past two decades, most notably a serious electrical problem reported in 2016 where ungrounded circuits/outlets caused smoking and melting when powered devices were connected. Earlier electrical concerns included improperly supported lighting installed in 2008, though this was subsequently corrected. The property has undergone various maintenance and improvement projects, including back wooden stair repairs in 2001, installation of new outside lights in 2008, and multiple sidewalk permits in 2007 and 2012.

Of particular note, the building faced multiple fire safety complaints related to "Shared Spaces" in September 2021 that resulted in violations being issued, though some were marked as duplicate complaints. The property has also been subject to recurring maintenance issues in the vicinity, as evidenced by numerous 311 calls in early 2025 reporting sidewalk conditions including graffiti and debris, though these were generally resolved promptly. While the building's structural and electrical maintenance history shows some recurring issues, many have been addressed through permits and completed work. The property has experienced periodic challenges related to its mixed-use nature, with historical records showing transitions between different commercial uses, including a coffee shop/cafe installation in 1995.

Risk rating

How 519-521 Valencia 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.
