Architect-Led Design and Streamlined ADU Planning

Every accessory dwelling unit is planned by licensed architects who know local neighborhoods and city standards.

As a dedicated ADU builder, we integrate feasibility, code research, and budgeting early so a homeowner can build an ADU with confidence.

Our approach pairs thoughtful space planning with durable materials and craftsmanship to enhance comfort and usability, creating ADUs that add flexible living space and long-term value.

Whether you're pursuing rental income, multigenerational housing, or a guest suite, we tailor each scope for your property and goals.

Our process includes site analysis, schematic options, and detailed scope definition that reduce surprises during ADU construction.

By aligning design intent and construction details at the outset, we help each homeowner streamline decisions, avoid scope creep, and protect property value while keeping timelines realistic and transparent.

Santa Ana ADU Permitting and Approval Expertise

Our team guides each ADU project through local regulations and City of Santa Ana plan checks with complete plan sets, faster approvals, and a network of licensed construction partners.

Planning an ADU in Santa Ana means understanding the residential zone, utility clearances, and ministerial permit timelines.

We prepare permit-ready drawings, Title 24 energy compliance, and precise responses to plan check comments so your accessory dwelling unit moves smoothly from submittal to approval.

For a Santa Ana ADU on a typical single-family zone, we verify setbacks, lot coverage, egress paths, and fire separation early. For multi-family sites, we analyze how many ADUs are allowed and where conversion opportunities are feasible within the applicable zone.

If your goal is to build an ADU for a family member or to generate rental income, we present smart options that fit your budget and speed while keeping quality at the forefront.

The result is a seamless path from concept to keys with clear communication, schedule checkpoints, and milestone-based billing tailored to your ADU project and permit strategy.

ADU Design in Santa Ana

With LADU's ADU Design Services, you'll get architect-led plans tailored to local lot sizes and styles, from Spanish Revival to cottage and modern.

Our flat-fee process covers site study, code checks, and multiple schematic layouts for detached ADUs and garage conversions.

We create permit-ready drawings that speed submittal and set your build up for success. Start with ADU design in Santa Ana to build an ADU that fits your property, delivers durable craftsmanship, and adds comfortable living space.

From compact studio ADU design to cottage ADU design with pitched roofs and porch details, we refine layouts to maximize storage, light, and privacy.

If a detached ADU is right for your lot and zone, we calibrate window placement, massing, and finishes to complement your main residence.

For a garage conversion, we evaluate structural conditions, foundation capacity, and utilities while planning efficient kitchens and baths that meet energy and ventilation standards.

We also offer custom ADU concepts with aging-in-place features, work-from-home alcoves, and sound isolation. At the end of design, you'll have coordinated drawings, specifications, and selections that reduce revisions during ADU construction and help secure a faster permit.

ADU Building Permits in Santa Ana

Our ADU Building Permit Services manage the full permit path with the City of Santa Ana, including forms, plan sets, Title 24, and responses to plan check comments.

Santa Ana offers streamlined review, parking relief near transit, and no owner-occupancy for ADUs permitted 2020–2025. Our permit team reduces back-and-forth hassles and keeps your schedule moving so construction can start sooner.

We coordinate utility notes, structural sheets, and any required corrections so the permit is issued quickly. When applicable, we help with addressing, school fee worksheets, and contractor-of-record coordination before permit issuance.

We also advise on permitting unpermitted ADUs where eligible, outlining what upgrades, inspections, or conversions are required to bring a unit into compliance.

Whether your site is in a single-family zone or a multi-family zone, we clarify parking exemptions near transit corridors and confirm setbacks, height, and fire rating requirements.

By preparing a comprehensive response to each permit comment, we minimize resubmittals and keep your ADU construction start date on track.

ADU Construction in Santa Ana

LADU's ADU Construction Services partner with licensed ADU construction teams for detached ADUs, two-story ADUs and garage conversions. You receive a coordinated handoff from design to build, clear bids, and site oversight focused on quality.

We align finishes with common local styles and deliver to the highest standards with a smooth, seamless process. Plan your ADU construction in Santa Ana with an architect-led team that reduces change orders and missteps.

Our construction services include detailed scopes, critical path schedules, and quality benchmarks that keep your ADU construction project moving.

For Spanish Revival properties, we blend stucco, clay tile, and arch details for cohesive curb appeal; for mid-century or cottage homes, we fine-tune siding profiles, window proportions, and trim so the new unit feels intentional.

Whether you're building a new backyard unit or opting for a garage conversion, we coordinate framing, MEP trades, and finish sequencing to prevent rework.

If an existing structure is not suitable for conversion, we can build a new permitted accessory structure with better insulation and layout. Throughout construction, our architects remain engaged to protect design intent, craftsmanship, and durability.
