Initial analysis

The multi-family residential building at 821-823 Jackson St is a 3-story, 5-unit apartment building located in Nob Hill, constructed in 1912 and currently owned by Jackson Cchca Llc. The building has undergone several significant renovations and improvements over the past decade, including a major accessibility upgrade in 2014 (costing $275,600) that included work on the first floor and basement, installation of accessible toilets and stairways, front entry modifications for accessibility compliance, and new HVAC and lighting. In 2018, gas meters were relocated at a cost of $20,000, with the work completed in 2020. The building has had multiple fire code violations in recent years, with the most recent being a sleeping area requirement violation issued in November 2023; however, most previous violations were abated, including multiple fire code violations in 2021 and 2020, and a blocked exits violation in 2018.

The property has experienced several maintenance and habitability issues in the past, particularly in early 2012, when multiple complaints were filed regarding mold, water damage, and plumbing problems, though these were subsequently abated. More recent concerns include two active "no heat" complaints filed in February 2012 that remain unresolved as of now. The building underwent various system upgrades and maintenance work between 2014-2020, including electrical improvements, plumbing work, and seismic upgrades. Recent 311 calls related to the property, primarily from late 2024, have mostly concerned garbage and debris on the street, while there was one water leak complaint in August 2024 that was resolved. The building had several fire-related incidents recorded in the past decade, though most were false alarms with no civilian injuries reported. The property's maintenance record shows an ongoing pattern of addressing both general upkeep and specific code compliance issues, particularly concerning fire safety systems and accessibility requirements.

Risk rating

How 821-823 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

Model explanation

What's driving this score

Number of units

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast

Moderate concern 19.3%
Severe concern 38.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
