811 Guerrero St, San Francisco, CA 94110

Located in San Francisco's Eureka Valley/Dolores Heights neighborhood, 811 Guerrero Street is a two-unit, two-story multi-family residential building constructed in 1900 and currently owned by the Trent R Dunphy Revocable Trust. The building underwent significant structural work in 1996-1997, including excavation of the basement crawl space and construction of a new foundation, along with shearwall and other revisions.

More recent improvements were made in 2010, when both exterior plywood sheathing was replaced and a new roof was installed, with the total cost of these improvements amounting to over $18,000. The property has experienced several maintenance and safety issues in the past few years, with the most notable being a sunken and damaged utility vault cover in 2022 that affected the sidewalk area. While there was one recorded case of work being done without proper permits (which was subsequently abated), this violation was not linked to any specific developer.

The building is currently dealing with some parking-related challenges, as evidenced by multiple complaints about blocked driveways and illegal parking between 2022 and 2024. The most recent incident of concern was reported in December 2024, involving glass debris on the property grounds. The property's maintenance history shows regular upkeep, particularly focusing on structural elements like the foundation and roofing systems, though there have been periodic issues with the surrounding public infrastructure such as sidewalks and street access.
