Initial analysis

The three-story, 12-unit multi-family residential building at 571 33rd Avenue in the Outer Richmond, owned by Louie Paul Y & Maria N 1991, was constructed in 1960 and has undergone several significant safety upgrades over the past decade. Most recently, in October 2023, a reroofing project was completed at a cost of $21,800. The building's fire safety systems have received particular attention, with the fire alarm system upgraded in 2022 to comply with San Francisco Fire Code requirements, and the main fire control panel replaced in 2018. These improvements were accompanied by the installation of low-frequency sounders in sleeping areas in 2021 to meet updated fire safety standards.

The building has experienced recurring issues with its fire safety systems, as evidenced by multiple fire violations and complaints between 2023 and 2020 related to alarm systems and extinguishers. Historical records from 2002 show a cluster of violations including problems with fire escape doors, fire escape ladders, and various other safety concerns, though these were all abated. The property has also had some interior maintenance issues over the years, including mold problems (2009, 2004), water leaks (2003), and a heating system complaint (2011), all of which were resolved. More recent concerns have been limited to routine maintenance and external issues, with several 311 calls regarding parking violations and sidewalk access between 2019 and 2024. The building's management has generally responded to and resolved complaints in a timely manner, with most violations being abated within months of being issued.

Risk rating

How 571 33Rd 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 1040 buildings in this neighborhood, 998 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 27.7%
Moderate concern 55.0%
Severe concern 17.4%
