Initial analysis

The 8-unit, 2-story multi-family residential building at 740 Anza Street, owned by Charles Y L Wong Bypass Trust, was constructed in 1959 in the Lone Mountain neighborhood. The property has undergone several significant safety upgrades in recent years, most notably a comprehensive fire alarm system upgrade completed in 2023 costing $27,400 to comply with San Francisco Fire Code requirements, including the installation of low-frequency sounders in sleeping areas and updating all devices to meet modern standards. The building completed its mandatory soft-story retrofit in 2016 as a Tier 3 building, demonstrating compliance with seismic safety requirements. Historical records show other maintenance work including window replacements in 2002 and reroofing in 1995.

The building has faced several safety and maintenance challenges in the past, most notably during a 2014 routine housing inspection which identified multiple issues including unsafe stair riser openings, guardrail problems, and missing handrails, though these were subsequently addressed. A 2004 inspection also revealed various fire safety concerns, including the need to recharge fire extinguishers and address smoke detector issues, which were all abated within a month. The property has experienced periodic graffiti incidents between 2009 and 2024, though these have generally been addressed promptly. Recent electrical permits filed in January 2024 suggest ongoing commitment to maintaining and upgrading building systems, though the status of some construction permits from early 2024 is currently listed as "filed".

Risk rating

How 740 Anza 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 519 buildings in this neighborhood, 483 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 48.2%
Moderate concern 41.3%
Severe concern 10.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
