Initial analysis

310 Holladay Ave is a 3-story multi-family residential building constructed in 1908, located in San Francisco's Bernal Heights neighborhood. The property has undergone several significant improvements in recent years, most notably the installation of new solar systems in late 2023, with two separate permits issued for solar panel installations including batteries (5.135 kW and 1.92 kW systems). Prior to this, in September 2022, the building received a complete reroofing project valued at $31,880. The building's maintenance record shows a historical plumbing issue from 2004 involving sewage leakage that was promptly addressed within two months.

The property has experienced some recent environmental and infrastructure challenges, particularly in early 2025, with multiple reports of garbage and debris on the street, including incidents involving shopping carts and loose waste, though most were resolved quickly. There was also a water leak issue involving a fire hydrant in January 2025 that required service attention. In 2021, there was a fire safety concern related to sprinkler/standpipe systems, which was resolved within two months. While there have been multiple fire violation citations in 2024 related to nearby properties (29 Patterson St and 30 Loomis St), these were not directly associated with 310 Holladay Ave and were all subsequently abated.

Risk rating

How 310-312 Holladay 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.

Neighborhood percentile

Out of 1276 buildings in this neighborhood, 447 are predicted to be safer.
