45 Costa St, San Francisco, CA 94110

The two-unit residential building at 45 Costa Street in Bernal Heights, owned by Jose Almanza, is a 1906 flats/duplex structure that has undergone several significant improvements and faced some regulatory challenges. Most recently, the property has been involved in solar panel installations, with three permits issued between 2022 and 2024 for a 6.12 kW system comprising 17 modules.

However, an active complaint from January 2022 remains regarding unauthorized installation of solar equipment. The building has seen various infrastructure improvements, including a water main replacement in 2013, gutter repairs in 2007 to address drainage issues, and multiple renovation projects in 2006 that required permits following a stop-work order for unpermitted remodeling. Historical records show the property had a roof replacement in 1995 and various building violations, though most have been resolved.

These included a complaint about improper gutter installation affecting neighboring property in 2007, and several fire code violations (including combustible vegetation issues) at nearby addresses in 2006 and 2018 that were abated. Recent activity around the property includes multiple municipal service requests between 2023-2025 regarding street cleaning, garbage removal, and infrastructure maintenance, as well as a tree-related issue. While the building has maintained basic compliance with major systems and received numerous system upgrades (including a planned service upgrade for solar), the active permit violation regarding solar panel installation suggests some ongoing regulatory issues.
