Augrented Insights Report

The property at 1726-1730 Polk Street is a two-story multi-family residential building with retail space, dating from 1920 and located in San Francisco's Nob Hill neighborhood. Owned by the Oshiro & Wirattigowit Trust, this building has undergone several significant maintenance and improvement works over the years. Most recently, in April 2024, a $34,000 re-roofing project was completed, following bathroom remodeling in 1996, electrical upgrades in 2005, and various plumbing improvements including sewer line work in 2013 and sink installation in 2012.

The building experienced fire-related issues in 1986 when repairs were done following fire damage in the restaurant, and multiple fire violations were recorded in 2007-2008 related to safety equipment and combustible storage, though these were subsequently closed. Recent concerns include a plumbing complaint from June 2023 regarding liquid discharge affecting neighboring properties, and two instances of graffiti reported in September 2023 (one being potentially offensive). The property has experienced multiple fire alarm activations over the years, usually determined to be unintentional, with one contained cooking fire incident recorded.

Several 311 calls have been made regarding the property's surroundings in 2023-2024, including reports of sidewalk defects and waste issues, though many were resolved without finding any violations. The building's commercial component appears to be active, with ABC and DPH restaurant referrals approved for 1730 Polk Street. While the property has a history of various maintenance and compliance issues, the majority have been addressed and resolved, with no recent violations recorded since 2021.
