Initial analysis

The three-story, 9-unit multi-family residential building at 405 27th Avenue in the Central Richmond neighborhood has been in operation since 1922 and is currently owned by Elvin P & Barbara L Juri Re. The building has undergone several significant safety system upgrades in recent years, most notably a major fire alarm system upgrade in 2023 costing $36,869 to comply with current fire code requirements, with both building and electrical permits issued and completed for this work. The property has a history of fire safety maintenance challenges, with multiple fire-related complaints, including issues with alarm systems and extinguishers reported regularly between 2016 and 2024, though all have been marked as "Condition Corrected" upon follow-up inspections.

The building experienced a cluster of fire safety violations in October 2004, including problems with fire escape ladders, combustible storage, door security, and smoke enclosure doors, all of which were abated by November 2004. Additional safety-related improvements have been documented, including plumbing work completed in 2017 for building sewer and trap systems, and a street space permit issued in 2017. Recent 311 calls related to the property and its immediate vicinity (2022-2024) have primarily concerned external issues such as sidewalk defects, graffiti on public infrastructure, and parking violations, rather than building safety concerns. The most recent building-related maintenance issues involve sidewalk damage and tree root problems, though these are external to the building structure itself.

Risk rating

How 405 27Th 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
4th percentile

Out of 2250 buildings in this neighborhood, 2160 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 30.4%
Moderate concern 48.3%
Severe concern 21.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
