501-511 Cortland Ave, San Francisco, CA 94110

The two-story multi-family residential building at 501-511 Cortland Ave in Bernal Heights, owned by Richard J Modolo, was constructed in 1913 and contains 6 units. The property has undergone several significant maintenance and improvement projects over the past two decades. Most recently, in 2024, the building received a complete reroofing at a cost of $35,250, demonstrating ongoing maintenance of the property's essential systems.

In 2019, Unit 1 underwent substantial renovations including a kitchen remodel with electrical upgrades and smoke detector installation, though this work initially generated a building complaint about unpermitted construction. Other notable improvements include a 2005 electrical upgrade to 200a 240v main service with 7 meters, and in 2017, approximately 80 linear feet of siding was replaced on the building's left side due to dry rot. The building's maintenance history shows regular attention to structural and safety issues, with multiple sidewalk repairs documented in 2002 and 2005 permits.

The property has undergone routine housing inspections in 1999, 2007, 2011, and 2013, with most inspections showing no significant violations. A heat-related complaint was filed and resolved in 2000. Recent years have seen increased activity in the area immediately surrounding the building, with multiple 311 calls between December 2024 and January 2025 regarding various local issues including garbage, graffiti, and parking concerns. However, these external matters appear to be more related to the neighborhood environment rather than the building's internal conditions.
