Initial analysis

The three-story, six-unit multi-family residential building at 1639-1643 Fulton Street, owned by Raul Arriaza, was constructed in 1904 and has undergone several significant improvements over the past decade. Most notably, the building completed its mandatory Soft Story retrofit in 2021 under Tier 3 compliance, which included seismic upgrades valued at $48,000 completed in 2017. Recent maintenance work includes dry rot repairs to the fire stairwell in the backyard (October 2023, $3,000) and a comprehensive kitchen remodel in Apartment B in 2021 ($12,000) that included new appliances and electrical upgrades. The property has addressed various structural issues over the years, including garage dry rot repairs in 2011.

The building's recent history shows an active response to maintenance and safety requirements, though there was a period of non-compliance with the Soft Story retrofit program in 2019 that required notification and abatement through 2021. While the building's internal systems have received attention, the surrounding area has experienced ongoing issues with street cleanliness and abandoned items, as evidenced by multiple 311 calls throughout 2024 regarding garbage, debris, and parking violations. These exterior issues, though not directly related to building safety or maintenance, may impact resident experience in the immediate vicinity. The building's documented history shows regular maintenance and adherence to safety requirements following the initial compliance issues in 2019, with no recorded fire incidents affecting the building structure or residents.

Risk rating

How 1639-1643 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
27th percentile

Out of 797 buildings in this neighborhood, 582 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Number of units

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

Building age

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

12-Month severity forecast
No violation 58.7%
Moderate concern 30.6%
Severe concern 10.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
