Our Planning-First Approach to San Diego ADUs

Every Honeycomb ADU begins with curiosity and precise planning, because more time spent ironing out the details means fewer surprises in build, and a finished space that truly feels like you.

Frequently Asked Questions About Building an ADU in the San Diego Area

How long does it take to design and build an ADU?

We spend extra time planning, so construction is smooth. On average, 3–5 months for design and permitting, and 5–7 months to build, depending on site complexity, material selections, and municipality review timelines.

Can you help me figure out if my property is eligible for an ADU?

Yes. Every project begins with a feasibility review where we evaluate your lot size, zoning, and utility access to confirm what’s possible before moving into design.

Can you design an ADU that matches my main home’s architecture?

Absolutely. Creating artful homages to your original architecture is part of the fun. Our design team studies your home’s proportions, materials, and character so the ADU feels like it’s always been part of your property.

Can you design an ADU for aging parents or accessibility needs?

Yes. We specialize in aging-in-place design. We happily include zero-threshold entries, wider doorways, accessible baths, and thoughtful circulation in your ADU design from the start.

Can an ADU include a full kitchen and laundry?

Yes. Detached ADUs can include complete kitchens and laundry, while JADUs (Junior ADUs) have partial or efficiency kitchens. Our team designs both.
