1614-1616 Laguna St, San Francisco, CA 94109

The property at 1596 Post Street in Lower Pacific Heights is a two-story mixed-use building constructed in 1960, currently owned by Hosoda Living Trust and containing two residential units. The building is undergoing significant proposed changes, with a filed permit in June 2024 for a 2,132 square-foot third-floor addition that would increase the structure's height from 27'3" to 38'8", including three new bedrooms, two new bathrooms, and a garage expansion.

This proposal also includes remodeling of existing spaces, notably converting the second floor from 2,375 square feet into a four-bedroom unit with increased bathroom facilities. The building's maintenance history shows regular upkeep, with major work including window replacements in 2012 (16 windows), reroofing projects in 1989 and 2008, and historical uses including a ground-floor produce business in 1987. Recent environmental challenges are evident from multiple 311 calls between September 2024 and January 2025, primarily relating to encampments and garbage issues in the vicinity, particularly affecting street and sidewalk conditions.

While these incidents do not directly impact building safety, they reflect current neighborhood conditions. The building's fire incident history shows two alarm activations - one due to malfunction and another false alarm, with no civilian injuries reported. The proposed third-floor addition, which is currently under review, represents the most significant change to the building's structure in decades, potentially adding substantial new residential capacity to the property.
