Initial analysis

The property at 3340-3342 18th Street is a two-story, four-unit multi-family residential building constructed in 1912, currently owned by the Berkeley-Storch Family Revocable Trust. The building has undergone several significant structural and system upgrades in recent years, including a voluntary structural upgrade in 2020 with the installation of a new steel frame at the front wall ($40,000), and a comprehensive electrical system upgrade in 2017 that replaced the main service from 100amp to 200amp with five meters and panels. The property has seen commercial space conversion work, including the transformation of a garage into commercial space with accessible facilities in 2014-2015, and the installation of new HVAC and lighting systems.

The building's history includes a notable incident in 2013 regarding an unauthorized basement unit, which was subsequently removed through permits showing the removal of kitchen and bathroom fixtures. This followed earlier concerns from 1998-2001 about various maintenance issues including plumbing problems, broken fixtures, and safety concerns that were eventually resolved. More recently, in 2020, there was a fire code violation related to sprinkler/standpipe systems that was promptly addressed. The property has maintained an active record of maintenance and upgrades, with the most recent work being primarily related to building systems and structural improvements. While there have been multiple 311 calls in the surrounding area regarding street conditions and parking issues, these are typical urban concerns and not specifically related to the building's maintenance or safety. The building's permit history shows regular maintenance and upgrading of systems, including plumbing, electrical, and structural elements, indicating active property management.

Risk rating

How 3340-3342 18Th 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.
