Initial analysis

The 7-unit, 3-story apartment building at 988 Union Street in Russian Hill, owned by the Survivors of Manling Har H Koo, was constructed in 1976 and has undergone several significant safety-related improvements over the years. Most notably, the building completed a mandatory soft-story retrofit in 2016-2017 (classified as Tier 3), which included engineering revisions valued at $75,000 to improve seismic safety. The building has maintained regular safety inspections, with records showing routine housing inspections in 1996, 2000, 2005, and 2007, during which some issues related to smoke detectors and emergency exits were identified in 2005 but were promptly addressed the same day.

Past improvements include reroofing work in 2008 (costing $15,000) and historical records from 1984 indicate the installation of a fire escape system and code compliance upgrades. The property has experienced minimal fire-related incidents, with only false alarms and a CO detector malfunction reported between 2007 and 2008, all of which resulted in no civilian injuries. Recent municipal service calls from 2023-2024 have primarily centered around street cleaning issues, including reports of garbage, human/animal waste, and hazardous materials on adjacent public spaces, as well as some parking enforcement matters. While these exterior maintenance issues have been consistently resolved, they primarily affect the surrounding area rather than the building itself. The most recent building permit activity was in 2017, suggesting no major structural modifications have occurred in recent years, while a July 2024 water leak incident was reported but not yet scheduled for repair at that time.

Risk rating

How 988 Union 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
25th percentile

Out of 1133 buildings in this neighborhood, 850 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.

Number of units

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

Building size

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

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 28.7%
Moderate concern 28.3%
Severe concern 43.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
