Initial analysis

The property at 3879-3881 18th Street is a two-unit, two-story multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood, owned by Stephen & Dinah Tao Living Trust. Built in 1907, this flats/duplex structure has undergone several significant modifications and experienced various maintenance issues over the years. The building's most recent major concern involved a sewage back-up discharge from the side sewer vent in November 2024, which was promptly resolved by the Public Utilities Commission. In 2014, there were safety concerns regarding an unsafe rear yard fence with a 15-foot drop that was addressed that same year. The building has a history of structural and maintenance issues, including a significant wall crack in 2008 that required reinforcement work costing $2,000 to address a violation notice, and multiple violations in 2004 relating to plumbing and electrical repairs that were resolved within a month. The property underwent a significant conversion in 1993 to revert from 4 units back to 2 units, during which time a stove was removed and door modifications were made. More recently, there has been a pattern of garbage and debris management issues in the vicinity, with multiple Recology street cleaning calls recorded between 2024 and 2023, including reports of abandoned furniture and electronics. While the building has experienced various maintenance challenges over the years, there have been no recorded fire incidents directly affecting the structure, and no civilian injuries have been reported.

Risk rating

How 3879-3881 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
67th percentile

Out of 1278 buildings in this neighborhood, 422 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.

Neighborhood location

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

Building age

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 70.8%
Moderate concern 16.0%
Severe concern 13.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
