Our Services

ADU solutions designed for San Diego properties and homeowners.

Detached ADU Planning

A detached unit offers maximum independence and works well on larger San Diego lots. We design footprints, parking, and utility access to match your property layout and neighborhood character. Homeowners in areas like La Jolla and Coronado often choose detached units for rental income or family housing.

Our designs maximize usable space while respecting setbacks and local design guidelines.

Attached & Junior ADU Design

Attached unit adding living space to existing structure.

Attached and junior ADUs share a wall or are smaller permitted units. Perfect for smaller lots or tight neighborhoods in San Diego. We handle shared utilities, fire separation, and entryway design to meet code and fit your home's aesthetic.

These options are popular in urban neighborhoods where lot size is limited but homeowner interest in rental or family housing is high.

Garage & Attic Conversions

Existing structures offer cost savings. We plan garage-to-ADU conversions and attic space development with structural review, egress windows, and proper ceiling height. San Diego's mild climate makes these conversions practical and efficient.

Perfect for homeowners seeking an affordable path to adding rental or guest space without new foundation work.

Why It Matters

A well-designed ADU solves multiple goals at once—from housing family members to generating rental income. Planning matters most.

Right-Sized Design Saves Money & Time

Poor planning leads to rework, code violations, and permit delays. Our designs anticipate San Diego's review process and local code specifics, reducing surprises and keeping your project moving forward logically.

Code Compliance Built Into Every Design

San Diego ADU rules cover parking, setbacks, height limits, and guest occupancy. We embed compliance into design so your plans pass city review without revision. A compliant design is faster and less stressful to build.

Property Value & Flexible Living

An ADU increases property appeal and long-term value. Whether you rent it, house a family member, or hold it for future flexibility, a solid design serves you for decades. San Diego's housing demand makes ADUs a smart investment.

Serving San Diego and Surrounding Areas

We know San Diego's neighborhoods, zoning patterns, and permit process inside out.

Local Knowledge & Neighborhood Expertise

Every San Diego neighborhood has different rules. Downtown and Midtown lot sizes differ from North County and Coastal communities. We tailor designs to your specific zone and neighborhood character—whether it's Mid-City, Ocean Beach, or Scripps Ranch.

From permit strategy to design refinement, we leverage 20+ years of San Diego construction and planning experience to position your ADU for approval and smooth building.

Frequently Asked Questions

Common questions about ADU design and planning in San Diego.

What types of ADUs can we build on a typical San Diego lot?

Detached, attached, junior, and conversion ADUs are all possible depending on your lot size, zoning, and setback rules. We assess your property and recommend the best fit for your goals and budget.

Do I need a separate meter and utilities for an ADU in San Diego?

Most ADUs require separate utility meters and infrastructure. Our design plans include water, sewer, electrical, and gas routing to meet code and simplify future operation and billing.

How do San Diego parking requirements affect my ADU design?

Parking rules vary by location and lot size. We ensure your design meets San Diego's parking code—whether that's one space, tandem parking, or an exemption for transit-friendly areas.

What permits do I need for an ADU in San Diego?

Building permits from the City of San Diego are required. Our designs and documentation are tailored to expedite the review and approval process with all necessary detail.

Can we design an ADU for a lot in a historic district or with HOA rules?

Yes. Historic districts and HOAs add design constraints. We incorporate architectural guidelines and homeowner association rules into our planning to ensure your ADU passes both approvals and aesthetics review.

How detailed are the designs you provide for planning?

Our planning-phase designs include site plans, floor plans, elevations, and code notes sufficient for city review and contractor bidding. We can also prepare detailed construction documents later as needed.
