Initial analysis

The building at 3109-3115 22nd Street is a three-story, 11-unit multi-family residential property located in the Inner Mission, owned by Montalvo Olinda and constructed in 1900. The property has undergone several significant structural and safety improvements in recent years, most notably completing mandatory soft-story retrofits in 2017 at a cost of $75,000 to comply with seismic safety requirements. Other major maintenance work has included reroofing in 2017 ($11,000), and the installation of a drinking fountain and ice machine water line in 2010. The building has experienced recurring maintenance issues, with multiple housing complaints filed in 2023 regarding building safety and maintenance requirements, including concerns about fire safety compliance, appliance maintenance, and carpet conditions. Historical records show previous violations from 2004 related to mold/mildew, gas utility safety, and a broken window pane, though these were abated within two months. The property had various permits for improvements throughout the 1980s and 1990s, including the installation of steel butterfly stairs and multiple electric sign permits, though some of these permits expired.

Recent 311 calls from 2024 primarily relate to street cleaning issues, including reports of abandoned mattresses and other debris, with a noise complaint related to entertainment reported and resolved in May 2024. The building's most recent planning records indicate approved modifications for ADA compatibility requirements and ABC referrals for alcoholic beverage licensing. While the 2023 housing complaints were marked as "Not Active," there have been several findings related to building safety requirements. The property's fire safety record shows two complaints, one in 2024 and another in 2007, both determined to have "No Merit." The building is classified under Tier 4 for soft-story retrofitting, with work completed and a Certificate of Final Completion issued.

Risk rating

How 3109-3115 22Nd 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.
