3234-3236 25th St, San Francisco, CA 94110

The property at 3234-3236 25th Street is a two-unit, two-story multi-family residential building constructed in 1925 in San Francisco's Inner Mission neighborhood, currently owned by Marc K Hellerstein. The building's records reveal several significant modifications and compliance issues over the past two decades. In 2006, substantial ground floor modifications were completed, adding two bedrooms, a storage area, and a full bathroom at a cost of $32,000, along with related electrical work including lighting and switch installations.

These modifications became the subject of multiple complaints filed in 2016-2017 regarding unauthorized construction and illegal unit conversion, though these complaints were eventually marked as "Not Active." The property underwent sustainable upgrades in 2015 with the installation of a 5.2 kW solar PV system comprised of 20 roof-mounted panels. More recently, between 2019-2020, there were significant concerns regarding short-term rental activity, with violations documented for unauthorized short-term rentals through Airbnb, including attempts to bypass regulations with new listings. These violations were eventually marked as abated.

In terms of recent neighborhood conditions, there have been numerous service calls in 2024-2025, primarily related to parking enforcement and street cleaning issues, including multiple reports of garbage and debris that were subsequently resolved, though none directly related to building-specific concerns. The building's history reflects a mix of improvements and compliance challenges, particularly regarding unauthorized unit modifications and short-term rental activity, with more recent concerns primarily focused on neighborhood maintenance issues rather than building-specific problems. The property has undergone several substantial modifications and improvements over the years, with most recent activity centered around compliance with short-term rental regulations and general neighborhood maintenance.
