Initial analysis

The four-story apartment building at 2455 Jackson St in Pacific Heights, built in 1900, is a 5-unit multi-family residential property currently under ownership of the Nancy E. Ryti Spousal Irrevocable Trust. The building's recent history is marked by significant structural and safety concerns, particularly regarding unauthorized construction work. In 2018, multiple complaints were filed about unauthorized roof work, resulting in Notice of Violations (NOVs) and subsequent investigations revealing unpermitted roof reframing, skylights, and deck modifications. This issue remains a significant concern, with recent complaints in 2024 about debris and damaged neighboring property. The building underwent mandatory soft-story retrofit work in 2014 (classified as Tier 3, with work completed and CFC issued), and several seismic retrofit attempts between 2015-2018, though there have been compliance issues as indicated by multiple filed permits and expired permits between 2018-2019.

The property has faced recurring issues with vacancy, as evidenced by multiple "vacant building" complaints between 2020-2024, and recent fire safety violations. In September 2024, violations were noted regarding blocked exits and storage in pathways, though these were subsequently corrected. Historical records show a pattern of maintenance and safety concerns, including earlier fire code violations in 2006 related to combustible materials and blocked exits. Infrastructure improvements documented in permits show efforts to address various building systems, including plumbing work in 2010-2011, electrical upgrades in 2004-2005, and multiple roof and interior repairs. The property has also experienced periodic issues with neighboring buildings, particularly concerning debris management and safety concerns during construction work, with some incidents resulting in damage to adjacent properties. Parking enforcement records from late 2024 show recurring issues with blocked driveways near the property, suggesting ongoing access challenges in the vicinity.

Risk rating

How 2455 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

Out of 963 buildings in this neighborhood, 905 are predicted to be safer.
