Initial analysis

The three-story multi-family residential building at 1448-1450 Jefferson Street in the Marina district, built in 1935, contains 2 units and is currently owned by Thomas G Zimmerman Survivor. The building's maintenance history shows several significant structural work permits from the early 1990s, including roof replacement, driveway slab work, and stucco repairs, though these permits have since expired. A street space permit was issued in 2009 with a minimal cost of $1. Currently, there have been no major building safety or maintenance issues reported since the 1991 structural work.

The property has experienced typical urban maintenance incidents over the past few years, with the most recent being a 2023 mailing request related to rent board fees and an overflowing city garbage can in July 2023. Other noteworthy incidents include a damaged tree in October 2020, resolved street lighting issues in 2021 and 2017, and various parking-related matters including a sidewalk parking complaint in December 2019 and parking enforcement requests in 2020 and 2021. The building's location has required typical municipal services such as tree maintenance, street cleaning, and temporary moving sign requests, with most cases being resolved through normal city processes. While there have been various maintenance and service requests in the vicinity, none appear to directly impact the building's habitability or safety, and there's no record of any building-specific complaints or violations in recent years.

Risk rating

How 1448-1450 Jefferson 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.
