Initial analysis

The 14-unit, three-story multi-family residential building at 410 44th Avenue in San Francisco's Outer Richmond neighborhood, owned by Thomas & Betty Ong Szeto Re, has undergone several significant safety and maintenance upgrades since its construction in 1964. Most notably, recent improvements include a comprehensive fire alarm system upgrade completed in 2023 at a cost of nearly $49,800 to comply with current fire codes, and a $28,000 re-roofing project completed in October 2024. The building has demonstrated a commitment to seismic safety, having completed a mandatory soft-story seismic upgrade in 2015 at a cost of $85,000. Historical maintenance records show attention to various building systems, including window replacements and stucco repairs in 2012.

The building has experienced periodic fire safety issues, particularly between 2005 and 2018, with multiple complaints and violations related to fire alarm systems, extinguishers, and sprinkler/standpipe systems, though most were promptly corrected or found to have no merit. A significant cluster of violations in 2006-2001 included issues with self-closing doors, combustible storage, egress obstructions, and fire extinguisher maintenance, all of which were subsequently resolved. The most recent fire complaint indicating blocked exits in late 2021 was closed with "No Merit." Building inspection records show regular routine inspections, with the last known complaint in 2018 regarding unpermitted construction work. The property has maintained active compliance with housing inspections and has completed all required seismic retrofitting as part of San Francisco's mandatory program for Tier 3 buildings. Recent 311 calls have primarily involved external issues such as garbage, debris, and parking concerns, with no direct impact on resident safety or building systems.

Risk rating

How 410 44Th 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
4th 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 30.4%
Moderate concern 50.7%
Severe concern 18.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
