Initial analysis

The property at 1235-1237 Jackson Street is a two-unit, two-story multi-family residential building located in San Francisco's Nob Hill neighborhood. Built in 1908 and classified as a Flats & Duplex building, it is currently owned by Jackson Street Trust. The building has undergone several significant maintenance and safety upgrades over the years, with the most recent being a comprehensive electrical system upgrade completed in April 2024 that included replacing fuses with circuit breakers and installing a new panel. This followed earlier improvements such as reroofing work in 2006 (costing $13,860) and historical records indicating various maintenance efforts including a stairway installation in 1991.

Recent incidents of concern include a construction noise complaint in March 2023, which was filed through the 311 system, and multiple reports of abandoned furniture and electronics on the street in mid-2024. There was also a documented issue with a damaged side sewer vent cover in April 2023, which was resolved through coordination with nearby property management. The building's safety systems experienced a smoke detector malfunction, though no injuries were reported. The property has a relatively low number of serious complaints on record, with most 311 calls relating to street cleanliness and parking enforcement issues in the vicinity rather than direct building concerns. While these various issues and improvements suggest active property management, prospective tenants should note the building's age and the typical maintenance requirements associated with historic structures.

Risk rating

How 1235-1237 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 1125 buildings in this neighborhood, 202 are predicted to be safer.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Neighborhood (ZIP code)
