Initial analysis

The 21-unit, three-story multi-family residential building at 1840-1842 Jefferson St in the Marina neighborhood, built in 1927 and currently under Survivor's Trust ownership, has undergone significant renovations in recent years. Between 2020 and 2024, ten units (101, 103, 104, 106, 204, 205, 206, and 305) have received comprehensive kitchen and bathroom remodels, including cabinet, sink, faucet, tile, and electrical work, with costs ranging from $18,000 to $60,000 per unit. A new hot water boiler was installed in June 2023, replacing the old unit with serial number 9090926 following a 2015 violation for improper permit status. The building has also experienced several fire safety concerns, with open violations for sleeping area requirements as of October 2024, though most previous fire-related issues from 2018-2023 have been marked as corrected or determined to have no merit.

Recent maintenance and operational activities include multiple plumbing and electrical upgrades, with the most recent work completed in Unit 306 in July 2024. Historical records show regular inspection activity, including routine housing inspections and responses to various complaints. Notable past violations from 2007 included issues with gas shutoff tools and instructional diagrams, though these were resolved by April 2007. There was one significant complaint in 2019 regarding unauthorized remodeling work in Unit 205 and six other units, which was addressed by June 2021. The property has generated several recent 311 calls (2024) primarily related to parking and street cleaning issues, with notably fewer internal building complaints in recent years. The building's documented history shows ongoing maintenance and upgrading of individual units, though recent open violations related to sleeping area requirements warrant attention, pending their resolution.

Risk rating

How 1840-1842 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

Out of 988 buildings in this neighborhood, 948 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 13.5%
Moderate concern 78.6%
Severe concern 7.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
