Initial analysis

The three-story, 8-unit apartment building at 700 31st Avenue in the Central Richmond neighborhood, owned by the Robin Nancy Won Revocable Trust, was constructed in 1928 and has undergone numerous maintenance and safety upgrades over the years. Most recently, in August 2024, the building received significant fire safety improvements with the installation of additional notification appliances throughout all units' sleeping areas, completing compliance upgrades to the fire alarm system. The building has experienced recurring maintenance issues related to its exterior elements, with multiple addresses to dry rot repairs, window replacements, and facade improvements. Notable recent exterior work includes the 2022 renovation of the south facade involving window trim waterproofing and stucco molding upgrades, and a 2016 project to replace south-side windows with historically accurate wooden units.

The building's safety systems have been a continuing focus, with multiple fire system upgrades including a 2021 control panel replacement and smoke detector installation, though it's worth noting that the current fire alarm system operates without supervision as there is no sprinkler system installed. Various building violations were addressed and abated in 2001 related to fire safety requirements, including egress obstruction, fire escape maintenance, and fire proofing materials, suggesting that the building has a history of addressing safety compliance issues. Recent 311 calls from 2024 primarily concern sidewalk maintenance issues related to tree root lifting, indicating some ongoing infrastructure challenges around the building's perimeter. The property has experienced several fire alarm activations, though these have consistently been determined to be either false alarms or due to system malfunctions, with no recorded civilian injuries from these incidents.

Risk rating

How 700 31St 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
7th percentile

Out of 2250 buildings in this neighborhood, 2092 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 40.5%
Moderate concern 44.1%
Severe concern 15.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
