Initial analysis

The property at 2601-2603 18th Street is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood, constructed in 1904. The building has undergone several significant improvements over the past two decades, with the most substantial renovation occurring in 2019, including a $40,000 kitchen remodel, electrical upgrades with new meters and panels, and plumbing work comprising bathroom updates. Earlier maintenance included a complete reroofing project in 2006 ($10,000) and essential plumbing work in 2009 involving replacement of the house trap and mainline sections.

The building has experienced multiple fire alarm incidents between 2007-2017, though all were determined to be false alarms or system malfunctions, with no injuries reported. Historical fire safety issues included a combustible storage violation in 2007, a fire escape condition that required correction in 2017, and an alarm system violation in 2009 - all of which were subsequently resolved. More recent concerns have primarily involved environmental issues, with multiple 311 calls between November 2024 and January 2025 reporting sidewalk debris, garbage, and a sewage discharge incident in December 2024 - these were generally addressed by city services. A December 2024 incident related to a tripping hazard was investigated and abated.

Risk rating

How 2601-2603 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, 500 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.

Building age

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

12-Month severity forecast
No violation 66.4%
Moderate concern 26.0%
Severe concern 7.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
