Augrented Insights

Initial analysis

The three-unit, three-story multi-family residential building at 1452-1456 Jackson Street in Nob Hill, owned by Yun Ming & Lena Chuey Hung, was constructed in 1908 and has undergone several significant maintenance and improvement projects over the years. Most notably, a complete reroofing project was undertaken in 2010 at a cost of $5,500. The building has experienced multiple maintenance issues that required attention, particularly concerning plumbing systems, with several reports of sewage backup problems between 2018 and 2021. A significant building complaint was filed in July 2023 regarding peeling paint and weather protection issues, which were documented as not active in July 2024, and there have been recurring concerns about lead paint hazards.

The property has a history of compliance inspections and violations, most notably in 2000 when multiple violations were recorded regarding fire safety, gas meter instructions, interior paint conditions, and lead paint hazards, though these were all abated by December 2000. There was also an investigation in 2006 regarding an allegedly illegal basement unit (1452A), which raised safety concerns due to barred windows, though this violation was eventually resolved. The building underwent various permitted improvements in 2009, including bathroom remodeling and electrical work, particularly in the basement storage area. Multiple street space permits were issued in 2008-2009, suggesting ongoing exterior or public space-related improvements. The property's maintenance record shows regular upkeep through various permits and responses to complaints, though the recent paint and weather protection issues reported in 2023 suggest some ongoing maintenance challenges. The building's overall history indicates active management, with most violations addressed through appropriate permits and inspections, though the recurrence of plumbing issues and recent paint concerns may indicate areas needing continued attention.

Risk rating

How 1452-1456 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

41th percentile

Out of 1125 buildings in this neighborhood, 664 are predicted to be safer.

Neighborhood location

Neighborhood (ZIP code)

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

12-Month severity forecast

No violation 37.5%

Moderate concern 31.4%

Severe concern 31.1%

Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
