Initial analysis

The 8-unit, 2-story multi-family residential building at 558 26th Avenue in the Central Richmond neighborhood, owned by Darren Wai Dong & Amy Lanyi, was constructed in 1964 and has experienced several notable events over its history. The building has had two significant fire alarm system issues in recent years, with the most recent complaint in July 2024 being corrected within 12 days, and a similar incident in July 2006 that was resolved promptly. A central alarm system violation was documented and resolved between 2000-2001, and there was an issue with insufficient hot water reported in March 1998, which was quickly addressed within two days. The building underwent reroofing work in 1998, although this permit is now listed as expired.

In terms of maintenance and environmental concerns, there have been multiple reports of garbage and debris in the vicinity of the building, with several cases of abandoned furniture and loose garbage documented between 2020-2024. Most recently, there were four consecutive reports of garbage issues in late 2024, though these were primarily related to street cleaning matters rather than building maintenance. The property has had three fire-related service calls for lock-out situations, smoke detector malfunctions, and invalid assistance, none of which resulted in civilian injuries. The building's documented history shows a pattern of fire alarm system maintenance needs and occasional hot water issues, while the exterior environment has experienced recurring challenges with street cleaning and debris management.

Risk rating

How 558 26Th 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 2250 buildings in this neighborhood, 1935 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Building size

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

12-Month severity forecast
No violation 61.1%
Moderate concern 23.4%
Severe concern 15.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
