Initial analysis

The 228-230 Linden Street property is a two-unit, two-story multi-family residential building constructed in 1908, currently owned by John G Pelka. The building has undergone several significant maintenance and improvement projects over the years, with the most substantial work occurring between 2007-2009, including a comprehensive lower unit renovation featuring kitchen and bathroom remodeling, electrical rewiring, and plumbing updates. In 2007-2008, the property underwent important structural work involving underpinning and tieback installations, likely in response to adjacent construction activity, with proper permits obtained and completed. More recently, the building has experienced some maintenance issues in early 2025, with multiple reports of garbage and debris (including Christmas trees) on the property, though these were promptly addressed by Recology. There have been several fire department responses to the building, primarily related to false alarms and minor issues such as trash fires and water problems, with no civilian injuries reported in any incidents.

The property's permit history demonstrates regular maintenance and improvements over time, with all major permitted work successfully completed. Recent activity in January 2025 has primarily focused on external issues rather than interior building conditions, with encampment-related reports being the only significant ongoing concern. The building's location in Hayes Valley continues to be impacted by urban challenges, as evidenced by the recent 311 calls, though these appear to be more related to street conditions than building-specific issues. The property has maintained compliance with necessary permits and inspections for major work performed, and historical records show proper documentation of all significant modifications and repairs.

Risk rating

How 228-230 Linden 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.
