Initial analysis

The three-story, five-unit multi-family residential building at 1106-1110 18th Street in Potrero Hill, owned by Zev Laderman and constructed in 1912, has undergone significant improvements and maintenance over the past several decades. Most notably, the building completed its mandatory seismic retrofit in 2014 with a $20,000 investment, achieving compliance with San Francisco Building Code requirements through the installation of new shear walls, anchor bolts, and holdowns, with the work officially classified as Tier 3 with Certificate of Final Completion (CFC) issued. The building has maintained regular upkeep, including a $15,000 kitchen and bathroom renovation project in 2002, though some earlier permits from 1999 for bathroom/kitchen remodeling and reroofing, as well as several street space permits in the early 2000s, have expired.

The building's safety systems underwent a comprehensive upgrade following a routine inspection in 2007, which identified issues with fire extinguishers and the central alarm system - all of which were promptly resolved by January 2008. Recent building activity has primarily involved external street-related matters, with the most notable recent issues being encampments reported near the property in 2024 and utility excavation work in August 2024, though these incidents were primarily public space concerns rather than building-related issues. The property has maintained a generally positive compliance record since its 2007 violations, with no active building code violations on record. Recent municipal service requests have mostly been related to street conditions and public space maintenance rather than building-specific issues, with the most recent interface with city services occurring in 2024 regarding encampments and utility matters.

Risk rating

How 1106-1110 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.
