Initial analysis

The 12-unit, 3-story apartment building at 1850 Fulton Street in the Lone Mountain neighborhood, built in 1917 and currently owned by Tony Lee Revoc Tr, has undergone several significant safety and maintenance upgrades over the past decade. Most notably, recent improvements include a comprehensive fire alarm system upgrade completed in August 2024 ($29,044) to enhance safety compliance, and reroofing work completed in July 2024 ($20,000). The building successfully addressed its soft-story seismic retrofit requirements, achieving compliance with a $50,000 retrofit of the ground floor garage completed in 2014.

The property has a history of addressing maintenance and safety issues, including multiple fire safety concerns that were corrected promptly between 2007 and 2019, such as fire escape access, combustible materials, and alarm system maintenance. Several electrical and structural improvements were made in the early 2000s, including beam replacements and foundation work. More recent issues documented include a 2015 inspection of a damaged pipe at the rear of the building and various electrical concerns in 2012, though these were subsequently resolved. The building's most recent permits demonstrate ongoing commitment to maintenance and safety improvements, particularly regarding fire safety systems. Historical violations from 2002 related to heating, ceiling damage, and moisture issues were all abated by May 2002, and there have been no similar recurring violations since then.

Risk rating

How 1850 Fulton 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
5th percentile

Out of 519 buildings in this neighborhood, 493 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 19.5%
Moderate concern 35.6%
Severe concern 44.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
