Initial analysis

The 4-unit, two-story multi-family residential building at 830 Fillmore Street in Alamo Square, owned by Klaus & Rosetta Zimmermann, has a mixed maintenance history since its construction in 1963. Most recently, in 2021, Unit 4 underwent significant improvements including kitchen and bathroom remodeling with electrical updates ($22,000), while Unit 2 received similar updates in 2008 ($4,500) including kitchen and bathroom renovations, along with electrical work. The building has experienced recurring issues with water management, as evidenced by multiple complaints in 2021-2022 regarding flooding in common areas and around the garbage access, and a 2021 complaint about improperly installed washer/dryer causing leaks. A series of violations was documented in October 2018, including problems with lighting in public areas, bathroom and kitchen flooring, mold issues, and fire safety concerns such as unserviced fire extinguishers and fire escape maintenance needs, though these appear to have been addressed through subsequent corrections.

The property's maintenance record shows regular upkeep of essential systems, including reroofing work in 1991 and 2014 (though the 2014 permit expired), and notable electrical improvements. Some historical issues include termite repairs in 1998, handrail installation in 1993, and a 2007 dispute regarding unpermitted remodeling work that was subsequently addressed through proper permitting. More recently, there have been several complaints about parking violations in early 2025, suggesting ongoing challenges with vehicle access to the property. While there were historical concerns about blocked exits noted in fire complaints from 2008 and 2009, these were determined to have no merit. The building's permit and violation history suggests regular maintenance and upgrades, though with periodic instances of water-related issues and building code violations that appear to have been resolved through proper channels.

Risk rating

How 830 Fillmore 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.

Neighborhood percentile
33th percentile

Out of 305 buildings in this neighborhood, 204 are predicted to be safer.
