Initial analysis

The 21-unit apartment building at 848-852 Jackson Street in Nob Hill, built in 1926 and owned by Chung Family Trust, has a significant history of building safety and maintenance issues, particularly regarding its fire safety systems. Most recently, in November 2023, a violation was issued concerning sleeping area requirements that remains open. The building has undergone several fire system upgrades, including a 2017 fire system replacement project costing $4,500 to install new control panels and pull stations, though this work was required to comply with San Francisco Fire Code requirements by 2021. There have been multiple fire safety-related violations and complaints, including issues with sprinkler systems in 2019 (abated), alarm systems in 2017 (duplicate complaint), and blocked exits in 2018 (condition corrected).

The building has undergone regular routine inspections by Housing Inspection Services, with the most recent occurring in 2018, which revealed issues including bathroom mold and ventilation problems that were eventually addressed. Historical records show various maintenance work including a complete reroofing in 1998, electrical system upgrades in 2003, and various fire safety related repairs such as the installation of new sprinkler heads in 2004. The property has also experienced periodic water-related issues, such as a 2018 complaint regarding bathroom ventilation and mold. The Nob Hill neighborhood around the building is currently experiencing some parking enforcement issues, as evidenced by multiple illegal parking reports in recent months, though these are external to the building's maintenance and safety concerns.

Risk rating

How 848-852 Jackson 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
4th percentile

Out of 1125 buildings in this neighborhood, 1080 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 9.6%
Moderate concern 55.0%
Severe concern 35.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
