70 Seal Rock Dr, San Francisco, CA 94121

The two-unit residential building at 70 Seal Rock Drive in San Francisco's Outer Richmond district, owned by Ninfa Maria D'silva Tr, is a two-story flats and duplex structure built in 1947. The property has undergone significant maintenance work in recent years, including a $15,000 re-roofing project completed in 2021 and substantial repairs to address dry rot damage around the garage door and front, which involved re-stuccoing and covered approximately 500 square feet at a cost of $21,000.

More recent infrastructure improvements include a complete sewer replacement in June 2020. The building's maintenance history shows attention to structural integrity, though there was one building complaint filed in April 2021 regarding work performed without a permit by Lone Mountain Homes, Inc., though this complaint is currently listed as not active.

The property has experienced some quality-of-life issues in the surrounding area, as evidenced by multiple 311 calls in 2023 and 2024, primarily related to parking enforcement matters and periodic noise complaints. These external issues appear to be unrelated to the building's condition or maintenance. Notably, the property underwent facade improvements including stucco replacement in 2018, and there was a tenant buyout recorded at an adjacent address (44 Seal Rock Drive) for two tenants in July 2018, though this is not directly related to the subject building.
