A studio ADU maximizes livability on compact Corona lots by optimizing daylight, storage, and convertible furniture layouts. We tune plumbing walls and sound control to simplify construction and cut waste, and we can outline financing options that match rent projections.

For investors building an ADU for long-term holds or short-term use, our builder network delivers reliable pricing.

Cottage ADU

A cottage ADU brings a classic porch, gables, and a warm interior to your Corona property, delivering an accessory dwelling unit that feels like part of your yard.

Thoughtful built-ins, durable siding, and energy-smart assemblies keep construction smooth and maintenance low.

If you're comparing layouts for future resale, rental housing, or multigenerational living, our team will share recent ADU builds and local comps to guide your choice.

2 Bedroom ADU

A 2 bedroom ADU is ideal for families and shared living in Corona, offering two real bedrooms, a full kitchen, and generous storage. We refine stacking, plumbing runs, and spans to keep construction efficient while creating privacy between rooms.

Ask our team about financing pathways, including construction financing bundled with permanent loans, so your budget aligns with projected rents.

A 3 bedroom ADU can dramatically expand multigenerational living in Corona while meeting space needs for work, study, and care.

We right-size living and dining to maintain flow and then coordinate structural, mechanical, and fire-rating details that support home construction quality in a compact footprint. With careful cost control and schedule planning, your accessory dwelling unit stays on track from slab to keys.

Garage ADU

A garage ADU transforms underused space into a high-performing residence in Corona, whether you convert an attached garage or build over a detached footprint.

We verify structural capacity, setbacks, and fire separation and then prepare details that make construction straightforward for your contractor and builder. During plan check, we coordinate any requested changes so the permit stays on track.

Junior ADU

A junior ADU is a compact solution carved from your existing home in Corona, perfect for caregivers, students, or supplemental income with minimal footprint. We plan efficient kitchens, shared bath access, and sound control to simplify construction and keep costs predictable.

If you need help comparing financing options or rent scenarios, we'll model payback and cash flow alongside permits and timelines.

Our Proven Process

Our proven process for building an ADU starts with a free site evaluation, feasibility study, and transparent pricing. Then, we develop your scope and schedule, finalize selections, and kick off pre-construction with engineering, energy, and submittals.

Because our roots are in custom homes, we bring disciplined budgeting and field management to ADUs, delivering a new ADU with fewer surprises and cleaner handoffs between design and trades.

We keep city stakeholders informed, including neighbors, inspectors, and lenders, so construction stays smooth from first dig to final clean.

Plan Review and Compliance

We align your plans with local building codes, fire separation, egress, and parking rules at the outset to reduce back-and-forth.

Our pre-review catches common issues in setbacks, height, and lot coverage, while our coordinators track submittal status and inspection milestones across all phases of construction.

Budgeting and Funding

Budget clarity matters. We outline multiple financing paths, from HELOCs and cash-out refinancing to accessory dwelling unit project loans so you can compare payments, reserves, and contingencies.

For qualifying clients, we coordinate with lenders to keep draw schedules aligned with construction progress.
