Initial analysis

The 147-unit multi-family residential building at 50 Rizal Street, owned by San Lorenzo Ruiz Center Inc. and constructed in 1979, has experienced several significant safety and maintenance issues over recent years, with the most pressing concerns centering around its fire safety systems. As of November 2023, there is an open violation regarding sleeping area requirements that needs to be addressed. Recent fire safety improvements are underway, with a permit filed in June 2024 to install additional notification devices, including 288 low-frequency sounders in all units' potential sleeping areas, as well as new remote power supplies to comply with fire code requirements.

The building has a documented history of maintenance challenges, particularly from 2018-2020, when multiple violations were issued regarding building systems and safety features. These included issues with smoke alarms, carbon monoxide detectors, stairs, heating, ventilation, and security features, though many of these have since been resolved. The structure underwent significant systems upgrades in recent years, including the replacement of its boiler systems in 2018 and 2015, a comprehensive fire alarm system upgrade in 2014, and exterior repairs such as reroofing in 2012. Historical records show earlier improvements were made in 1987 to bring the building into compliance with certain standards, though some permits from that period expired without completion.

Risk rating

How 50 Rizal 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.

Neighborhood percentile

Out of 23 buildings in this neighborhood, 13 are predicted to be safer.

Model explanation

What's driving this score

Number of units

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

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.

Property class (A15)

The assessor's property-class code, which correlates with building type and the violation rates the model expects.

12-Month severity forecast
No violation 61.1%
Moderate concern 31.7%
Severe concern 7.3%
