OUR MISSION STATEMENT
Creating thoughtfully designed living spaces that blend innovation with quality, delivering tailored solutions that inspire comfort and set new benchmarks in design excellence.
Who We Are
ADU Design Studio creates accessory dwelling units and custom homes around your property, needs and style. We work with clients online, from early ideas through developed plans and architectural construction documents.
Plans, design & project support
Choose an existing ADU model with an SD or DD package, consultation and a preliminary property test fit. For bespoke ADUs and single-family homes, we develop your design in separately commissioned phases. We also offer consultant, permit and construction-phase coordination.

A studio plan. Or a design of your own.
We help you choose and adapt an existing ADU model, or develop a custom ADU or single-family home around your property. Consultation is part of each purchased package or commissioned design phase.

Request a project proposal →How phase pricing works
SD explores the idea, DD resolves the design and CD develops the architectural drawing set for permit review and construction. Listed fees are for each phase, not a combined full-project price. Your proposal states the deliverables, consultation time, revisions and total fee before work begins.
Custom SD and DD each include two consolidated revision rounds on the agreed scheme. DD includes two review meetings. Site studies use supplied information; construction documents require verified site information. Complex sites, conversions, two-story projects and multiple units receive a project-specific quote. Engineering, surveys, energy compliance, consultants and agency fees are separately scoped. Permit approval is not guaranteed.
Coordination, when you need it
Project & construction support
Starting from $150 / hour
Additional coordination and construction-phase support with an agreed scope and time cap.
City permit coordination
Starting from $2,000
Help organize consultant inputs and the permit process. Scope and fees are agreed in advance.
Consultation and coordination already included in a purchased package or commissioned phase are not charged twice.
