Initial analysis

The 6-unit, 2-story multi-family residential building at 3945 20th Street in the Eureka Valley/Dolores Heights neighborhood, owned by Orest & Irene Wesely Tr, has undergone several significant improvements over the past decades. Most recently, in 2023, the building received an upgrade to its fire alarm system, including the installation of new components to meet current safety codes, with a similar permit issued in November 2023 for additional fire safety improvements. The building completed its mandatory seismic retrofit in 2017, achieving compliance with San Francisco's seismic safety requirements as a Tier 3 soft-story building. Earlier renovations included substantial work on Unit #4 in 2009 (approximately $26,000), involving kitchen and bathroom upgrades, electrical improvements, and plumbing work. The building has a documented history of proper maintenance and safety compliance, including a significant fire repair project in 2005 ($45,000) addressing electrical, plumbing, and structural issues, and earlier improvements such as reroofing in 1995 and various code compliance updates in 1986.

The property's maintenance record shows regular attention to safety and habitability standards, with routine housing inspections conducted in 1999, 2004, 2010, and 2014, with no violations noted in 2010. While there have been several 311 calls regarding the property in recent years, these primarily relate to external issues such as parking enforcement, sidewalk cleanliness, and street lighting concerns, rather than building-specific problems. The building's recent fire safety upgrades and completed seismic retrofit demonstrate ongoing commitment to maintaining safety standards, though prospective tenants should be aware of the property's vintage (1960 construction) and its history of a significant fire repair in 2005. The property has maintained an active status in terms of addressing both routine maintenance and mandatory safety requirements, with particular attention paid to fire safety improvements and seismic retrofit compliance.

Risk rating

How 3945 20Th 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.

Model explanation

What's driving this score

Number of units

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 58.5%
Moderate concern 19.7%
Severe concern 21.8%
