Initial analysis

The property at 1877-1879 Chestnut Street is a two-unit, two-story multi-family residential building with a significant maintenance history, built in 1924 and currently owned by the Mary J Caraker Living Trust. Over the years, the building has undergone several major maintenance and improvement projects, including multiple roofing works in 1991 (two permits totaling $11,600), foundation reinforcement in 1990, and an interior kitchen remodel in 2004 which included electrical upgrades comprising installation of lights, switches, receptacles, circuits, and a panel. Earlier structural improvements included stair repairs in 1993. The most recent building maintenance occurred in 2013, with another roofing project for which permits were issued.

The property has been the subject of several complaints and service requests over the years, with the most notable being a housing inspection inquiry in 2015 regarding proper permits for rental units, though this complaint was marked as not active. Recent years have seen recurring issues with street cleanliness and waste management, including multiple reports of garbage, debris, and receptacle placement on public property between 2018 and 2024. The building has also experienced periodic problems with vehicles blocking driveways, with six documented complaints between 2018 and 2024, though enforcement officers were often unable to locate the offending vehicles. The most recent service requests involve garbage and debris issues in 2024, which have been resolved according to city records. The property's historical permit record shows regular maintenance activity, particularly regarding the roof, which has been addressed approximately every decade since the 1990s.

Risk rating

How 1877-1879 Chestnut 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.
