804-806 Guerrero St, San Francisco, CA 94110

The property at 804-806 Guerrero Street is a two-unit, two-story multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood and built in 1900, currently owned by the Ark Dick C & Diana J Living trust. The building has undergone several significant maintenance and repair projects in recent years, most notably in 2017 when multiple housing code violations were identified and subsequently addressed, including issues with inadequate heat, window repairs, and problems with an unpermitted porch. These violations triggered a series of permits and corrections, culminating in the removal of an unpermitted porch and related repairs.

The violations from December 2016 included serious issues such as inadequate heating systems, various building deficiencies, fire safety concerns, and the need for smoke detection improvements, all of which were officially abated by September 2019. More recent history shows ongoing maintenance activities and some infrastructure challenges, including a sewage backup incident in October 2022 and sidewalk issues that were resolved. The property has been the subject of multiple 311 calls in the past year, primarily related to street cleaning and parking enforcement issues.

Several planning records indicate previous proposals to modify the rear porch and stairs, though these were withdrawn or marked as closed. The building's maintenance history shows a mix of essential repairs and improvements, with particular attention paid to addressing health and safety concerns that were documented through official complaints and violations in 2016-2019, with no active violations currently on record. The most recent building permit activity from 2019 involved minor siding repairs to non-street facing areas of the building.
