Initial analysis

The three-unit multi-family residential building at 607-609 Frederick Street, owned by Erik David and Seema Lindskog, has undergone several significant renovations since its construction in 1904. Most notably, in recent years, there have been multiple updates to the building's infrastructure and amenities, including the installation of washer/dryer units and related plumbing and electrical work between 2022 and 2023, and basement improvements involving sheetrock installation and electrical work in 2021. However, the property has experienced some regulatory and safety concerns, particularly in 2019-2020, when multiple housing violations were recorded, including issues with water damage, mold, flammable storage, damaged windows, and electrical systems. These violations, though all marked as "Not Active" after February 20, 2020, suggest past maintenance challenges.

The building's recent history shows ongoing attention to infrastructure improvements, with several completed permits for plumbing and electrical work in 2022 and 2023. There were also some unauthorized construction activities reported in mid-2021 regarding basement work, which resulted in complaints to building inspectors. The property management has maintained relatively consistent records of addressing violations and completing necessary repairs, though some issues have recurred, such as reports of peeling paint and window problems. Recent concerns from 2023-2025 include a rodent/insect infestation reported in November 2023 and several graffiti incidents near the property, though these are primarily external to the main building. The building has a history of various improvements dating back to 1988, including termite repairs, horizontal additions, and multiple kitchen and bathroom remodels. The most recent major building system upgrades include water heater installation and electrical system improvements in 2022-2023, indicating ongoing efforts to modernize the building's facilities.

Risk rating

How 607-609 Frederick 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.
