Maximizing Property Value in the San Francisco Bay Area: Navigating the New Landscape of ADU Development with AB 1033 and Government Code 65852.2

For San Francisco and Bay Area property owners, California's housing law updates, particularly Government Code 65852.2 and Assembly Bill 1033 (AB 1033), have significantly enhanced the appeal and value of Accessory Dwelling Units (ADUs). These legislative updates not only make ADU construction a more attractive investment due to potential rental income and increased property value, but also streamline the process and introduce the possibility of selling ADUs as independent condominiums.

Innovation in Investment: Explore San Francisco's Breakthrough in Commercial to Residential Adaptive Reuse

San Francisco's urban development is entering a new era with transformative amendments to the Planning Code, offering innovative investment opportunities in office-to-residential conversions. As a leading architecture, civil, and structural engineering company, we are excited to explore the implications of San Francisco's Commercial to Residential Adaptive Reuse and Downtown Economic Revitalization Ordinance, enacted on July 5, 2023. This legislation unlocks the adaptive reuse of commercial spaces for residential living, a significant step in real estate development.

Seismic and Soft-Story Retrofit in San Francisco

San Francisco is part of a larger effort to increase seismic safety in California, with the state legislature introducing a new law in 2019 that requires all soft-story buildings to be retrofitted by 2030.

Known for its beautiful views, vibrant culture, and unique architecture. However, the city is also prone to seismic activity, making it essential that residents take the necessary steps to protect their homes and businesses from potential earthquakes. One of the most effective ways to do this is through seismic and soft-story retrofits.
