Initial analysis

The 2-story multi-family residential building at 308-312 25th Ave in the Central Richmond neighborhood is a 1909 structure containing 6 units. The property has undergone several significant improvements in recent years, with the most substantial renovation occurring in 2015 involving a comprehensive kitchen and bathroom remodel in Unit 3, along with electrical upgrades including a new 60-amp sub-panel installation. During the same period, necessary repairs were made to address dry-rotten egress wood stairs in Unit 304, highlighting ongoing maintenance of vital building components. The building experienced notable issues in the early 2000s, particularly in 2004 when a series of violations were recorded related to interior conditions, including mold/mildew problems, water damage, and heating system deficiencies, though these issues were resolved by September 2003. Earlier maintenance records from the 1990s show multiple unit renovations, including bathroom and kitchen improvements in units 308 and 310.

The property has maintained a generally active maintenance schedule, with the most recent building permit activity focused on routine unit upgrades and repairs. Historical violations and complaints from 2004 as well as earlier citations regarding exterior stairway conditions (2008) indicate periods of deferred maintenance, though these issues appear to have been adequately addressed based on subsequent repair work and completed permits. Recent 311 calls primarily relate to external issues such as tree maintenance and street cleaning rather than building-specific problems, suggesting improved overall building conditions in recent years. Three recorded fire-related incidents were primarily for service calls and alarm system malfunctions, with no civilian injuries reported, indicating regular safety system maintenance.

Risk rating

How 308-312 25Th 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Building size

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

12-Month severity forecast
No violation 54.8%
Moderate concern 31.7%
Severe concern 13.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
