Initial analysis

The 9-unit, 3-story apartment building at 600 24th Avenue in the Central Richmond neighborhood, owned by Jiangs Property LLC, was constructed in 1927 and has undergone several significant renovations and faced various maintenance challenges over the years. The property completed its mandatory soft-story seismic retrofit in 2016, achieving Tier 3 compliance, and has had multiple unit improvements, including attempted addition of a 10th unit in 2016 (permit ultimately cancelled), window replacements (2005), and several repairs to address dry rot issues in various locations. The building has undergone multiple routine safety inspections between 1999 and 2014, revealing various maintenance issues that required attention, including security concerns with doors and stairs (2013), lighting problems in common areas (2015), and multiple fire safety inspections between 2016-2021 showing recurring concerns with alarm systems and extinguishers, though all were eventually marked as "Condition Corrected." A significant cluster of violations was recorded in 2002 related to various interior conditions, including water damage, lead paint concerns, and building maintenance issues, all of which were abated by 2005. The property has seen regular maintenance and improvements over the years, including plumbing and electrical upgrades, though it had some historically persistent issues with fire safety equipment as evidenced by multiple violations between 2006-2021. Recent 311 calls from 2024 suggest ongoing challenges with debris management and parking enforcement in the vicinity of the building, while a single tenant buyout of $22,000 was recorded in late 2015.

Risk rating

How 600 24Th 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
2th percentile

Out of 2250 buildings in this neighborhood, 2205 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 29.6%
Moderate concern 48.3%
Severe concern 22.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
