Why choose this ADU?

The big impact of a smartly designed 1020 sq ft ADU

The Sequoia ADU floor plan delivers the perfect balance of comfort, functionality, and flexibility. At 1,020 square feet, this 3-bedroom, 2-bathroom layout offers significantly more living potential than smaller units, without exceeding ADU size limits in San Diego County.

This ADU offers full-sized living in a smart, space-efficient footprint. With three bedrooms, two bathrooms, and an open-concept layout, the Sequoia comfortably accommodates families, roommates, or extended relatives—all while fitting easily on most San Diego residential lots.

With three private bedrooms and two full bathrooms, the Sequoia can command higher rental rates compared to smaller ADUs. Whether used for long-term tenants or short-term rentals, this layout increases your earning potential and improves ROI—making your ADU a true income-generating asset.

This floor plan is perfect for housing elderly parents, adult children, or live-in caregivers. The separated bedroom layout and dual bathrooms allow for privacy and independence, while keeping loved ones close. It's a cost-effective and compassionate alternative to assisted living or off-site rentals.

The Sequoia adapts to your changing needs. Use the third bedroom as a home office, creative studio, or guest suite today—and convert it back to living space later. This level of flexibility ensures your ADU remains valuable for decades to come.

Adding a 1020 sq ft, 3-bedroom ADU can significantly raise your home's market value. In high-demand areas like San Diego, this type of unit appeals to buyers and renters alike—creating both instant and long-term equity.

Thoughtful design features like a double-vanity bath, open living space, and indoor–outdoor connectivity make daily life in the Sequoia comfortable and functional. The floor plan is intentionally laid out to enhance privacy while maintaining a connected, welcoming atmosphere.

Built around your needs

Custom ADU floor plans or pre-approved?

Designed for your lifestyle

Pre-approved plans may save time, but they’re built for the average homeowner—not for you. Custom ADU floor plans are tailored to your specific needs, whether that means a home office with built-in storage, a private suite for aging parents, or a larger kitchen for entertaining.

Optimized for your property

Every lot is different. With a custom design, we can strategically place windows, doors, and outdoor access to maximize sunlight, privacy, and flow. Custom plans allow for smarter site orientation and better use of space—something pre-approved templates simply can’t match.

Future-proof & ROI

Custom ADUs are built with your long-term goals in mind—from aging in place to future rental income. We consider every detail, from smart home integration to zoning flexibility, so your ADU grows with you.

The total cost for building a Sequoia ADU can vary depending on several key factors, including site conditions, selected finishes, design flexibility, building permit, and permitting costs related to local zoning regulations. In San Diego, typical design-build costs range between $350 and $500 per square foot, placing the total project cost between approximately $357,000 and $510,000.

Our team expertly manages each stage—including helping you factor in construction costs upfront—to ensure efficiency and minimize delays.

In California, there's no explicit statewide limit on the number of bedrooms an ADU can have. However, the practical limit typically depends on local zoning rules, lot size, maximum allowed square footage (commonly capped at 1,200 sq ft for detached ADUs), and building code requirements. Most accessory dwelling units typically have between 1–3 bedrooms due to these size constraints, though in some areas or larger lots, a 4-bedroom ADU could be possible. It's always best to check with your city or county's local planning department to confirm what's allowed for your specific property.

California’s ADU regulations simplify construction: detached ADUs can be up to 1,200 sq ft, with an 800 sq ft minimum guaranteed regardless of bedroom count. Required setbacks are 4 feet for side/rear property lines, with typical height limits between 16-18 feet. Parking isn't required for ADUs near transit, historic districts, or converted structures. Single-family homes can add one ADU and one Junior ADU; multifamily properties can have multiple ADUs. ADUs must include full-sized kitchens and meet building codes, and local approvals must be completed within 60 days. Verify specific local guidelines, as they may vary.

In California, you generally cannot sell an ADU separately from the primary home. Accessory Dwelling Units (ADUs) are intended to remain part of the main property's parcel and typically can't be subdivided or sold independently. However, recent state legislation (such as Assembly Bill 587) has opened possibilities for selling ADUs separately under specific conditions, including certain nonprofit affordable housing developments or qualified tenancy-in-common (TIC) arrangements, but these scenarios are uncommon and subject to strict regulations. For most homeowners, an ADU remains legally tied to the primary property, contributing to overall property value but not eligible to be sold separately. Always check with your local jurisdiction for specific rules regarding subdivision or separate sale of ADUs.
