Initial analysis

The 7-unit, 2-story multi-family residential building at 4645 Balboa Street in the Outer Richmond neighborhood, owned by the Navarro Family Living Trust, was constructed in 1957 and has undergone several significant renovations and faced various safety inspections over the years. Most notably, the building completed its mandatory soft-story retrofit in 2024 (with a cost of $90,000 completed in 2017) after initially being cited in 2021 for non-compliance with San Francisco's earthquake safety requirements. The property has a documented history of addressing various building code requirements, including a 2010 correction of unauthorized modifications in Unit #1, repairs to dry rot in the garage in 2004, and bathroom improvements in 1993. Multiple routine inspections have revealed recurring safety concerns, particularly regarding fire safety - including issues with fire escape access and fire extinguisher maintenance - though these violations have generally been abated promptly, with most being addressed within a few months of citation.

Recent maintenance issues have primarily involved the building's utility systems, with multiple sewage backup incidents reported through 311 calls in 2024, as well as some parking enforcement matters noted in the vicinity. A tenant buyout was recorded at 710 48th Avenue in January 2021, involving two tenants and totaling $11,785. The building's most recent routine inspection in 2014 prompted several violations regarding ventilation, building permits, and safety equipment, all of which were subsequently addressed. While the property has had its share of violations and maintenance issues, many were addressed through proper permits and timely corrections, with the recent completion of the soft-story retrofit program bringing the building into compliance with current seismic safety requirements.

Risk rating

How 4645 Balboa 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

Out of 1040 buildings in this neighborhood, 1019 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 32.8%
Moderate concern 25.8%
Severe concern 41.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
