ADU Planning and Design in San Diego

Build an ADU with a plan set that fits your home in San Diego. We tailor layouts to Spanish Revival streets, coastal conditions, and Transit Priority Areas while balancing privacy, natural lighting, and backyard access.

Comprehensive Design and Permit Coordination

Fixed design pricing includes site study, floor plans, elevations, engineering coordination, and permit submittal.

Our process accounts for stormwater, wildfire zones, and solar-ready roof configurations so your accessory dwelling unit is designed to pass review the first time.

If you plan to remodel the main house at the same time, we phase drawings to keep the permit path clear and avoid conflicts between scopes.

For a homeowner looking to build an ADU as a rental, guest suite, or multi-generational space, we align room sizes, kitchen and bath layouts, and storage so the ADU lives larger than its square footage.

From custom ADU finishes to durable materials for long-term tenants, we match design goals to budgets and timelines.

If you are looking to build an ADU this year, we can map your ADU project from early feasibility to construction start, including energy compliance, utility upgrades, and any necessary permit clearances.

What Sets Us Apart

• Site-specific layouts for narrow lots, alley access, and backyard privacy
• Styles to match local homes, including Spanish, cottage, and modern infill
• Plans set up for ministerial review and faster approvals
• Solar-ready roof planning and Title 24 coordination

Our detail-first approach ensures ADUs integrate seamlessly with your home in San Diego while meeting zoning, parking, and utility criteria.

We focus on window placement, entries, and landscaping to create privacy between the main residence and the ADU, and we coordinate grading, drainage, and structural details to streamline the permit.

For a San Diego ADU near transit or coastal zones, we review special overlays so your ADU construction aligns with state law and local guidelines on day one.

ADU Services Offered in San Diego

ADU Design

From concept plans to permit-ready documents, our ADU Design Services organize the right information for reviewers and the field, including accurate dimensions, elevations, sections, and energy notes.

Our team listens to how you live and uses that to shape room sizes, storage, and natural light strategies so the ADU works for day-to-day life.

ADU Building Permits

LADU's ADU Building Permit Services keep your project on track. We assemble complete submittals, respond to plan check comments, and track the permit status to keep your ADU project moving.

This includes utility sign-offs, Title 24, structural coordination, and any corrections that arise during review.

Permitting Unpermitted ADUs

If you have an existing space built without approvals, our Permitting Unpermitted ADUs Services can help.

We document conditions, prepare as-built drawings, and create a compliance plan to legalize the unit. Our contractor network can help address required upgrades so the final inspection is successful.

ADU Construction

We hand off clear, constructible plans to vetted construction partners and remain available for field coordination so your ADU construction runs smoothly.

From foundation details to finishes, our ADU Construction Services make sure the builder has exactly what they need to deliver quality results.

Spanish Style ADU

For Spanish-style ADUs, we design stucco forms, clay tile roofs, arches, and wrought-iron accents that complement historic Spanish Revival streetscapes in San Diego.

Proportions, trim, and landscape details are tuned so the accessory dwelling unit looks authentic and is neighbor friendly.

Studio ADU

For small footprints, we craft multi-functional layouts that include Murphy beds, built-in storage, and efficient kitchens so studio ADUs feel open, bright, and livable. We optimize window placement for privacy and daylight on tight lots.

Cottage ADU

If you prefer a traditional cottage-style ADU, we can shape gables, lap siding, and porch details that blend with older neighborhoods and create curb appeal. Inside, we plan cozy, flexible rooms that work for guests or long-term tenants.

2 Bedroom ADU

Families often choose 2 bedroom ADUs for flexibility. We configure closets, laundry, and baths efficiently so circulation is simple and the unit feels spacious. This option is ideal for extended family or a high-demand rental.

3 Bedroom ADU

When you need more space, a 3 bedroom ADU can boost rental income and accommodate multi-generational living. We refine structural spans and energy measures so larger ADUs still meet budgets and timelines.

Garage ADU

An ADU garage conversion is a cost-savvy way to add housing. We assess foundations, clearances, and utilities early to streamline the permit and minimize surprises during construction.

Junior ADU

A JADU carved from your existing home can be a fast path to rental income. We coordinate fire separation, egress, and kitchenette standards to meet code while keeping costs controlled.

Why a Detached ADU Is Typically the Best Choice

A stand-alone backyard unit offers the most privacy between the main house and the ADU. We situate the building to maximize sun, shade, and open space while balancing setbacks, height, and utility runs.
