4347 17th St, San Francisco, CA 94114

The property at 4347 17th Street in Corona Heights is a two-unit, two-story multi-family residential building constructed in 1902, currently owned by Richard B. and Maria E. Mazer.

The building has undergone recent maintenance with a $12,000 reroofing project completed in March 2024. The property has experienced recurring issues with graffiti, including an offensive incident reported in January 2024 and a non-offensive case in December 2023. There has been significant recent activity regarding street cleanup, with multiple reports of abandoned garbage and debris between July and November 2024, including furniture, appliances, and yard waste. A blocked sidewalk incident involving construction materials was reported in October 2024, though this was resolved promptly.

Several significant planning applications have been filed for the property, all related to a proposed conversion of the two existing units into a single-family residence, with plans to construct a new unit on top of the existing garage. These proposals, submitted by Andy Forrest, were either withdrawn or marked as informational, suggesting they did not proceed to approval. A building complaint was logged in 2016 regarding incorrect signage and an expired no stopping sign, though this case is now marked as not active. The property's historical permit records include the recent roofing work, which represents one of the few building improvements in recent years.
