Initial analysis

1900 Jefferson Street is a three-story, 15-unit multi-family residential building constructed in 1930 and currently owned by North Point Investments LLC. The property has undergone extensive renovations since 2020, including the controversial addition of five ADUs in the garage area, which generated multiple tenant complaints regarding construction noise and work beyond permitted scope. Between 2019-2022, significant upgrades were made to individual units (202, 203, 301, etc.), including complete rewiring, plumbing updates, and reconfigurations of interior spaces to convert units from one-bedroom to larger configurations. The building has a history of permit compliance issues, particularly during 2020 when several complaints were filed about unpermitted work and construction during health orders. Notably, there was a violation for operating an unpermitted boiler in July 2019, though this was resolved within a month.

Recent improvements include roof work completed in 2020 and various unit upgrades involving electrical, plumbing, and interior remodeling. The building has experienced multiple fire alarm activations, though all were determined to be false alarms or system malfunctions with no injuries reported. The property has an active maintenance history with numerous permits issued for various improvements, indicating ongoing investment in building maintenance and upgrades. Recent 311 calls (2023-2024) primarily concern external issues such as tree maintenance and sidewalk conditions, though these are not directly related to building performance.

Risk rating

How 1900 Jefferson 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 988 buildings in this neighborhood, 939 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 13.3%
Moderate concern 74.8%
Severe concern 11.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
