Frequently Asked Questions
Everything you need to know about building an ADU in Santa Barbara.
Most single-family lots in Santa Barbara qualify for at least one ADU. We confirm setbacks, access, utilities, parking, and any coastal or hillside reviews in a fast feasibility check — so you know exactly what's possible before investing further.
Timelines vary by scope and location. We map the permit path up front, submit complete plans, and manage reviews so approvals move smoothly. Most permits are processed within 60 to 120 days depending on complexity and coastal review requirements.
Detached guest cottages, attached ADUs, garage conversions, and above-garage suites. Each is designed to local standards and your specific goals — whether that's hosting family, generating rental income, or adding long-term home value.
In most cases, yes — with certain local rules in place. We advise on current requirements and design every ADU for quiet comfort, privacy, and durability so it's rental-ready from day one.
We plan electrical, water, sewer, gas, and trenching — and coordinate any required panel or service upgrades. All utility work is mapped during the feasibility phase to avoid mid-project surprises.
Most projects begin four to eight weeks after design and permits are complete. We place supplier holds during design so the schedule is clear and materials are secured before demo begins.
