Initial analysis

The 4-unit, 3-story multi-family residential building at 548 26th Avenue in San Francisco's Central Richmond neighborhood, owned by the Katz Revocable Living Trust, has undergone several significant improvements since its construction in 1988. Most notably, in September 2016, the building received a substantial solar energy upgrade with the installation of three separate rooftop PV systems totaling 11.4 kW. The property has maintained active upkeep, including a complete reroofing in 2008 ($7,500), window replacements in 2004, and the conversion of a storage room to an exercise room in 2003, which included comprehensive electrical upgrades and the installation of a full-building sprinkler system.

The building's safety systems have been tested over the years, with some notable instances requiring attention. In May 2018, the property experienced multiple fire safety inspections addressing alarm systems, extinguishers, sprinklers/standpipe systems, and blocked exits, all of which were promptly corrected by June and July 2018. Earlier issues from 2002 regarding combustible storage, egress obstructions, and central alarm system repairs were all resolved by July 2002. The building's fire safety infrastructure appears to be generally reliable, with regular maintenance demonstrated through permit records and prompt resolution of violations. The most recent routine inspection in 2011 and a structural complaint in 2008 were both quickly addressed, indicating responsive management to building maintenance and safety concerns.

Risk rating

How 548 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
76th percentile

Out of 2250 buildings in this neighborhood, 540 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.

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 80.0%
Moderate concern 12.6%
Severe concern 7.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
