Initial analysis

The 6-unit multi-family residential building at 3327-3337 23rd Street in the Inner Mission, owned by J & N International Enterprises, has a concerning record of maintenance issues and resident complaints spanning several years. Most notably, in May 2018, the building faced multiple violations related to interior conditions, including problems with toilets, floor coverings, walls, windows, and general dilapidation, along with a rodent infestation, all of which were abated by October 2018. The property, constructed in 1900, has shown recurring maintenance challenges, with significant complaints and violations emerging regularly between 2018 and 2024. These include a series of building condition complaints in 2020 related to disrepair, graffiti, and unsanctioned construction, as well as a 2024 complaint about hazardous electrical wiring tied to scaffolding. Recent complaints in the latter part of 2024 primarily concerned garbage and debris in the vicinity of the property, with multiple reports recorded between October and November 2024.

The building's permit history shows limited activity, with only two permits on record: a street space and sidewalk repair permit from 2009 and a completed permit from 1982. The property has experienced various habitability issues over the years, including insufficient heat (2018), problematic bathroom ventilation, improperly installed toilet, and maintenance concerns such as broken mirrors, lifted floors, and old carpets. The most recent identified concern, filed in August 2024, involved a potentially hazardous electrical condition, though this complaint has been transferred to another department for further review. The building's documented history suggests ongoing challenges with maintenance and resident conditions, though many of the most serious violations from 2018 were officially abated.

Risk rating

How 3327-3337 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.
