3946-3948 26th St, San Francisco, CA 94131

The property at 3946-3948 26th St in Noe Valley is a two-story, four-unit multi-family residential building constructed in 1900, currently under the ownership of Bertram Family Trust B. The building has undergone significant recent renovations, particularly in 2022-2024, with multiple permits showing extensive work on the rear building including kitchen and bathroom remodels, electrical upgrades, and window replacements. Most notably, there are two active complaints regarding unauthorized work and permit violations from 2022-2023, including interior reconfigurations beyond permitted scope, unauthorized addition of half bath, improper wall construction, and unpermitted vinyl window installations.

The property has a history of compliance issues, including multiple violations in 2004-2005 related to building safety and fire requirements, though these were abated. Previous improvements include a 200-amp service upgrade in 2012, insulation work in 2013, and various unit-specific upgrades including window replacements and heating system installations. Recent activity has also generated multiple parking enforcement calls in 2024, though these are external to the building's condition.

The building's documented history reveals typical maintenance and upgrading patterns for a property of its age, with previous concerns about window functionality in 1994, mold issues in 2010, and various routine inspections. The most recent renovation activity has generated significant scrutiny from regulatory authorities, with two active violations as of 2024 related to unauthorized construction work. Multiple permits filed between 2022 and 2024 suggest ongoing improvements to the property, though some have been withdrawn or marked as "filed" rather than "issued." The property has received recent attention from both building inspectors and regulatory enforcement, indicating active monitoring of compliance issues. The most significant current concerns appear to center around ongoing permit compliance issues as of 2023, with allegations of continued work beyond approved permits and failure to properly address previous violations.
