Initial analysis

The 20-unit, three-story apartment building at 420 29th Avenue in San Francisco's Central Richmond neighborhood was constructed in 2011 and is currently owned by St Peters Supportive Housing. The building has experienced several significant fire safety issues over recent years, with the most recent violations occurring in December 2024 regarding alarm system maintenance, and December 2023 concerning sleeping area requirements, both of which have since been abated. The building's fire safety systems were initially installed during construction in 2010-2011, including a fire alarm system, fire sprinklers throughout all floors, and evacuation maps on each floor. However, there have been recurring issues with the alarm systems, as evidenced by a violation recorded in February 2017, which was corrected.

The building's mechanical systems have undergone various improvements, including the installation of two hot water boilers in 2018 (though initially installed without proper permits), two new Lochinvar boilers in 2013, and radiant heating for the entire building in 2011. Additional sustainable features were incorporated during construction, including six solar water collectors on the roof and a 360-gallon storage tank in the basement mechanical room. The building experienced a construction-related complaint in 2010 regarding an unexpected height difference between the north and south sides, though this was quickly abated within one day.

Risk rating

How 420 29Th 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, 2228 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.

Construction type: wood frame

Wood-frame construction (type D) is the most common SF residential type and has specific maintenance risks.

12-Month severity forecast
No violation 17.3%
Moderate concern 73.4%
Severe concern 9.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
