Initial analysis

The 20-unit multi-family residential building at 3466-3476 18th Street in the Inner Mission, built in 1908 and currently owned by the Guerrero V Espinoza Trust, has undergone several significant safety upgrades and faced various maintenance challenges over recent years. Most notably, the building completed a mandatory soft-story retrofit in 2017 (Tier 4) at a cost of $171,360, and is currently undergoing a fire alarm system upgrade to comply with San Francisco Fire Code requirements, with work expected to be completed by the end of 2024. The property has experienced multiple health and safety issues, particularly during a cluster of complaints in late 2016, including heating system failures, fire escape maintenance problems, lead paint concerns, and appliance malfunctions, many of which remain open as of October 2023. While some historical violations have been resolved, including heating system and stair repairs in 2017-2018, recent fire violations from December 2023 regarding sleeping area requirements indicate ongoing compliance challenges.

The building's maintenance history reveals attention to critical systems, with a new domestic hot water boiler installed in 2014, electrical service upgraded to 200 amps in 2011, and various safety-related improvements completed over the years. Recent 311 calls from late 2024 show regular issues with street and sidewalk cleanliness, including reports of debris and graffiti. The property has also been subject to several routine inspections and generated multiple repair orders over the past two decades, addressing issues such as staircase maintenance, window problems, and kitchen ventilation concerns. Notable recent improvements include the 2017 installation of Ufer grounding and a 2024 fire alarm system upgrade, indicating ongoing commitment to building safety and code compliance, though some historical violations from 2016 remain unresolved as of October 2023, particularly related to fire safety systems and lead paint hazards.

Risk rating

How 3466-3476 18Th St'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 2380 buildings in this neighborhood, 2190 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 size

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

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 12.3%
Moderate concern 65.2%
Severe concern 22.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
