Initial analysis

The property at 3679-3685 23rd Street in Noe Valley is a two-story, four-unit multi-family residential building constructed in 1900, currently owned by Caribou LLC. The building has undergone several significant renovations over the past two decades, with the most substantial work occurring in late 2011 when electrical systems were upgraded with a new 200-amp service, rewiring of the second floor, installation of smoke detectors, and plumbing improvements including the relocation of water heaters. This phase of work also included bathroom and kitchen renovations in one unit, completing a $26,000 improvement project. Earlier maintenance records from 2004 show repairs to the rear stairs were completed, and gas houseline extensions were performed in 2007.

The building has undergone regular routine apartment inspections by Housing Inspection Services in 2001, 2009, and 2016, with no violations found during the 2009 and 2016 inspections. A building violation was filed in December 2016 regarding documentation, but this was resolved by January 2017. In recent months (April-October 2024), there has been an unusually high frequency of garbage and debris-related incidents recorded near the property, with eight separate reports of loose garbage, furniture, and yard waste, though all were promptly resolved by city services. An abandoned vehicle complaint from April 2024 was also addressed and resolved through citation and towing. While the garbage-related incidents represent the most significant recent activity associated with the property, these were related to street cleaning rather than direct building maintenance or resident issues.

Risk rating

How 3679-3685 23Rd 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.
