Initial analysis

The 6-unit multi-family residential building at 400-412 27th Avenue in the Central Richmond neighborhood was constructed in 1980 and is currently managed by Survivors Trust The. The property has undergone several significant repairs and maintenance work over the years, with the most recent being a complete reroofing project in 2021 costing $13,000, and a sewer line and house trap replacement in 2014 (though this permit has since expired). The building experienced notable issues in 2010 when multiple violations were documented in Unit #2, including black mold in the kitchen and hallway, water damage through ceiling fixtures and windows, deteriorated waterproofing, and problems with hardwood flooring at the fire escape access window. These violations were ultimately abated by June 2010. In 2001, the building faced several fire safety violations, including egress obstructions, problems with the central alarm system, and issues with combustible storage, all of which were resolved by October 2001.

The property has demonstrated regular upkeep through various maintenance work, including sidewalk repairs (2003) and more recent garbage and debris management as evidenced by multiple 311 calls in 2023-2024. The most recent service calls have primarily been for street cleaning in the surrounding area, including reports of abandoned furniture and glass, which were promptly addressed by city services. Historical records show an interesting note from 1992 regarding a Planning Application for an apartment building with commercial space, 4 units, and 3 stories, though this appears to be an earlier configuration different from the current 6-unit structure. Similar to many urban settings, there have been periodic issues with street cleanliness around the property, as indicated by multiple 311 calls for garbage, debris, and waste removal in the past two years.

Risk rating

How 400-412 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

Out of 2250 buildings in this neighborhood, 1822 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.

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.

12-Month severity forecast
No violation 61.2%
Moderate concern 28.7%
Severe concern 10.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
