Initial analysis

The two-unit residential building at 10-12 30th Street in Bernal Heights, owned by Annamaria Flamburis, has undergone several significant maintenance and improvement projects since its construction in 1908. Most notably, the property experienced water-related issues in 2019 when a toilet supply line rupture in the upper unit resulted in water damage, requiring repairs to both units' bathrooms and kitchens at a cost of $10,000. That same year, the building received comprehensive upgrades including window replacements (21 windows, with 9 street-visible wood sash units), kitchen cabinet installations, and electrical rewiring in the bathroom and kitchen. The building has seen consistent maintenance of its core systems, including a roof replacement in 2017 ($21,300), partial foundation work in 2015 ($8,500) involving replacement of footings and posts, moisture remediation in the yard/patio/basement areas, and HVAC improvements with the installation of gas-efficient furnaces in 2019.

The building's maintenance history shows attention to both structural and comfort improvements, though there have been some concerns worth noting. A significant complaint was filed in March 2016 regarding overgrown weeds and pest issues that reportedly affected neighboring properties, though this complaint is no longer active. The property has experienced plumbing challenges, with a sewer line issue reported in 2001 that took several years to resolve. More recently, there was a sewer-related incident on the property in December 2022, which was resolved by PUC Sewer Operations. The building's systems upgrades include multiple window replacements (2014 and 2019), kitchen renovations, and various electrical improvements. While there have been several 311 calls regarding the property's vicinity (mostly related to street cleaning and parking), these are typical for urban environments and not necessarily indicative of building-specific issues.

Risk rating

How 10-12 30Th 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.
