Yes. We manage the entire permitting and plan-check process, including coordination with architects, engineers, and local jurisdictions. Our projects are planned permit-first to avoid delays and redesigns.
Every project is unique. Costs depend on size, site conditions, utility access, finish level, and jurisdiction requirements. We provide realistic pricing after evaluating your property, not ballpark numbers that change later.
Timelines vary by scope and city approvals. Most ADUs take 6–10 months, while custom homes typically range 12–18 months. We establish realistic schedules upfront and keep clients informed throughout the build.
Initial consultations are used to evaluate feasibility, scope, and next steps. This allows us to determine whether your project is a good fit and provide accurate guidance moving forward.
You communicate directly with your builder. No layers, no sales handoffs. We believe clear, consistent communication is critical to a successful project.
The first step is scheduling a consultation so we can review your property, goals, and city requirements. From there, we outline feasibility, budget expectations, and the next steps toward construction.
