AI summary

The three-unit, three-story mixed-use building at 3438-3442 Mission Street in Bernal Heights, owned by Geronima S Belen-bautista L, has a complex history dating back to its 1900 construction. Most recently, in August 2024, a permit was filed for an accessible entry installation. The property has undergone significant plumbing work, including a sewer lateral replacement in 2021 and house trap installation in 2013, though there have been recurring sewer issues, with complaints in 2021 about leaks affecting neighboring properties. The building's history includes multiple safety and maintenance concerns, particularly between 2016-2019, when violations regarding lead paint hazards, window insulation damage, and a potentially illegal unit were documented. Several fire safety violations were recorded in 2009, including obstructed fire escapes and missing fire extinguishers, though these were subsequently addressed.

The property's commercial space has seen various modifications, including a 2013 change of use from limited restaurant to full restaurant, and substantial improvements in 2004 including kitchen equipment updates and electrical system upgrades. Historical records show earlier significant work from the 1980s and 1990s, including fire escape installation, emergency repairs, and foundation work. Recent maintenance issues have included basement flooding and water heater problems in 2016, though some of these were addressed through subsequent repairs. The building has experienced recurring sewer-related concerns, as evidenced by multiple 311 calls in 2023-2024 regarding sewage issues. While many historical violations have been resolved, the pattern of plumbing and infrastructure challenges suggests ongoing maintenance needs.

Risk rating

How 3438-3442 Mission 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.
