653-655 Fell St, San Francisco, CA 94102

The two-unit residential building at 653-655 Fell Street in Hayes Valley, built in 1880, has undergone significant recent improvements under the ownership of Redwood Property Investors. Most notably, in 2023-2024, there have been substantial safety upgrades including the installation of a dedicated fire alarm system with sprinkler supervision ($6,500), new fire sprinkler systems throughout the ground floor ADU unit, and comprehensive electrical upgrades with a 200-amp main service panel installation.

The property has also undergone extensive interior remodeling, including the renovation of six bathrooms and installation of new HVAC systems with two forced air furnaces, kitchen hoods, and bathroom fans. The building's recent history includes some periods of regulatory scrutiny and complaint activity, particularly in 2019 when multiple building permit applications were suspended per Planning Department request, and a 2021 complaint about unpermitted construction work. However, these issues appear to have been resolved, with the most recent violation from 2019 being abated in October 2024.

The property has maintained active compliance with fire safety requirements, with continuous updates to fire alarm and sprinkler systems. Recent work has primarily focused on preservation and safety improvements, including facade changes, landscaping, and clarification of sleeping areas, as documented in multiple recent building permits. The building's structure consists of two stories, containing modernized units that have received extensive system updates and aesthetic improvements, maintaining its historical character while enhancing safety and functionality.
