Initial analysis

The 4-unit, 2-story multi-family residential building at 703-709 18th Avenue in the Central Richmond neighborhood, owned by the Sang T Henninger Trust, was constructed in 1922 and has undergone several significant maintenance and safety-related improvements over the years. Most notably, the building received both reroofing work in 2010 (cost: $14,000) and foundation work in 1990, along with the installation of new decking on rear stairs in 1996 and stair safety improvements in 2004. The property has experienced recurring fire safety compliance issues, particularly in September 2002 when multiple violations were recorded regarding fire extinguisher maintenance and fire escape ladder functionality, though all were promptly abated by September 30, 2002. A routine inspection in 2010 also noted the need for self-closing devices at exterior doors, which was subsequently addressed.

More recent history of the property shows no building-specific violations or complaints since 2010, though there have been various municipal service calls in the vicinity between 2016 and 2024. These include responses to parking issues, maintenance work on catch basins, and handling of graffiti on nearby signs. The most recent building-related service call was in December 2023 for catch basin maintenance, which was resolved. Regular maintenance and prompt response to violations suggest active management of the property, though prospective tenants should note the age of the building (101 years old) and its history of requiring various safety-related improvements over the years.

Risk rating

How 703-709 18Th 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, 1822 are predicted to be safer.

Model explanation

What's driving this score

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.

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 63.7%
Moderate concern 21.0%
Severe concern 15.3%
