1. The Surge in California ADU Construction
Accessory Dwelling Units (ADUs) have revolutionized residential development in California. Under Title 24 building standards, navigating solar compliance is essential for obtaining city building permits and avoiding final inspection rejections.
2. When is Solar Mandatory on a California ADU?
Under CEC Title 24 standards, all newly constructed detached ADUs require dedicated solar systems. Attached ADUs and conversions of existing permitted spaces (such as interior garage conversions) are exempt unless major structural roof expansions occur.
3. Fast-Track Plan Checks with AD Solar
AD Solar works directly with general contractors and architects to provide PE-stamped electrical diagrams, structural roof attachment calculations, and Title 24 compliance certificates in 24 to 48 hours.
