Most single-family lots in California qualify for an ADU under state law. We'll evaluate your property's zoning and setback requirements during our initial consultation.

In San Diego County, detached ADUs can be up to 1,200 sq ft. Junior ADUs (JADUs) are capped at 500 sq ft and must be within the existing home. We design ADU floor plans across the full range — from compact 500 sq ft studios to 1,200 sq ft two-bedroom units — and can show you what fits your specific lot.

A detached ADU is a separate structure on your lot — a backyard cottage or converted garage. An attached ADU shares a wall with your main home, like a converted garage or a new addition. Both require the same permit-ready drawings and building department approval. We design both types throughout San Diego County.
