Additions & ADU FAQs

An ADU (Accessory Dwelling Unit) is a secondary living space on your property — such as a converted garage, a basement unit, or a detached structure. We design and build ADUs and home additions, handling the project from concept through construction. Feasibility depends on your lot and local zoning, which we review with you early on.

Additions and ADUs vary widely based on square footage, foundation and structural work, and finishes. Because they involve new construction, we put together a detailed, itemized estimate after reviewing your property and goals in a free consultation.
