Initial analysis

The property at 1256 Stanyan Street is a two-story, three-unit multi-family residential building constructed in 1900, currently owned by Raymond Jaihyun Cho. The building has undergone substantial improvements and safety upgrades over recent years, with major projects including the installation of a comprehensive fire sprinkler system and fire alarm monitoring in 2019 ($15,000 total), seismic strengthening in 2018 ($25,000), and various unit remodels and infrastructure upgrades. Recent work has focused on crawl space modifications, with a permit issued in July 2024 for filling underneath the rear pop-out and adding storage, though this has generated at least one recent neighborhood complaint regarding backyard elevation changes.

The building has a history of addressing safety and maintenance issues, with several completed fire safety improvements, including new furnaces, fire alarms, and bathroom renovations. While there were multiple code violations noted between 1996-2009 regarding handrails, fire escape maintenance, and smoke detectors, these were all resolved, and there have been no active violations since. Recent concerns include several open tree maintenance requests from 2024 and ongoing issues with uncovered wires/cables creating tripping hazards, as well as concerns about sidewalk clearance. The most recent major building work, as of late 2024, involves HVAC system upgrades, including new furnace installations with 80% efficiency systems and associated electrical work. The property has maintained compliance with building codes through regular inspections and permit renewals, though there was one investigation in 2019 regarding work beyond permit scope that was ultimately closed as not active.

Risk rating

How 1256 Stanyan 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 526 buildings in this neighborhood, 53 are predicted to be safer.
