Initial analysis

The 6-unit, 2-story multi-family residential building at 418 25th Ave in Central Richmond, owned by S Lew Family LLC and constructed in 1962, has undergone several significant upgrades to enhance safety and comply with current regulations. Most recently, in March 2023, the building received a fire alarm system upgrade costing $15,600 to meet San Francisco Fire Code requirements, followed by a related electrical panel upgrade project in December 2024 that involves replacing seven electrical panels from Federal Pacific to Square D panels. The building previously completed important safety improvements including a soft-story seismic retrofit in 2016 (Tier 3, cost $40,000) and an earlier fire alarm system modification in 2023 that included installing low-frequency sounders in sleeping areas to meet fire code requirements.

The building's safety record shows minimal violations, with only four fire-related and gas shutoff tool issues documented in 2001, all of which were promptly abated within one month. Recent complaints have been resolved, including a routine housing inspection in late 2001 and a construction-related noise complaint in December 2024 that was addressed within a week. There were also two street cleaning issues in January 2021, which were promptly resolved by Recology. The most recent fire alarm system complaint from November 2024 was marked as "Condition Corrected," indicating responsive management of safety concerns. Overall, the building's maintenance record demonstrates consistent attention to safety upgrades and prompt resolution of issues as they arise, with no active violations or pending complaints.

Risk rating

How 418 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, 1575 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

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.

12-Month severity forecast
No violation 79.8%
Moderate concern 14.2%
Severe concern 6.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
