Initial analysis

The property at 405-423 Locust Street is a 3-story, 6-unit multi-family residential building with 3 ground-floor commercial units, constructed in 1908 in the Presidio Heights neighborhood. The building has undergone significant improvements over the past two decades, most notably completing mandatory soft-story retrofits for both residential and commercial portions in 2017 at a cost of $90,000, demonstrating compliance with seismic safety requirements. Recent renovations include multiple bathroom remodels (2010-2012), electrical system upgrades (including a 400-amp underground conversion in 2003), and the resolution of past building violations related to unauthorized unit conversions and commercial use of residential spaces in 2003-2009.

The property has experienced recurring maintenance issues in recent years, particularly concerning tree-related damage to sidewalks (with two open cases in late 2023), while multiple 311 calls in 2023-2024 have reported issues with garbage management and street cleaning. There were also some mechanical equipment noise complaints in late 2023. The building's fire alarm system has had three false alarms recorded, though no injuries were reported in any incidents. The most recent building inspections and permits suggest active management of the property and attention to infrastructure maintenance, with the soft-story retrofit completion being a significant safety upgrade.

Risk rating

How 405-423 Locust 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 181 buildings in this neighborhood, 170 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.

Building size

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

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.

12-Month severity forecast
No violation 30.2%
Moderate concern 45.0%
Severe concern 24.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
