ADU Builders in Jurupa Valley, Eastvale & the Inland Empire

ADUs, garage conversions and room additions, with foundations, framing and the permit and inspection sequence considered together.

Detached ADUs

A detached accessory dwelling unit creates living space in a separate building. Start by describing how the space should function and how it relates to the existing home. The location, ground conditions and construction access need review before the building scope can be defined. We build detached units, garage conversions and attached additions, so we can help you compare approaches for your lot.

Treat the structure and the work around it as one planning conversation. Foundation details, framing and access for deliveries affect one another. Photos of the proposed area and any existing drawings help us identify questions that should be resolved before an estimate becomes a construction agreement.

Garage Conversions

A garage conversion starts with the building already on the property. Its slab, footings, walls and roof need review against the proposed residential use. Older additions and garage conversions can have undersized or missing footings. Existing concrete should be verified before new loads are assigned to it.

Tell us what you know about the garage, including earlier alterations and available permit records. A conversion may involve structural openings, deteriorated framing and interior work as well as a new layout. The estimate should distinguish the existing structure from the repairs and changes shown in the plans.

Attached ADUs and Room Additions

An attached ADU involves connections to the existing home. Room additions are also part of our building services, but an extra bedroom or family room is not automatically a separate dwelling. Describe the intended use first so the plans and construction scope address the right project.

Our addition work includes foundation connections, framing and roof tie-ins. Existing conditions are checked before the connection is defined. Weather protection and the separation between occupied rooms and construction should be discussed when the household will remain on the property.

Foundations and Concrete

Footings and slabs support everything above them. Our work includes new footings, foundation connections and concrete work, with structural details determined by engineered plans and verified site conditions. Review the proposed building area together with nearby paving and drainage rather than treating the slab as an isolated item.

Framing

Framing work includes beams, headers, shear walls and hold-downs installed to the engineered details. Structural openings require a load path to the foundation. Sheathing, weather barriers, windows and roofing protect the structure before interior finishes proceed. See our room additions and framing services for more about our building work.

Utility Coordination

Confirm the ADU-specific utility coordination scope with us before contracting. Bring available information about existing connections and any design work already completed. Responsibilities for utility applications, service changes and trade work are set for each property and written into the contract.

Permits and Plans Coordination

Our building services include plan submittal, permitting and the inspection sequence as part of the contract for work that requires them. Drawings should be coordinated with conditions verified on site. Identify missing design or engineering information early, and agree who supplies it. Approval rests with the reviewing authority, and construction must follow the approved scope.

Construction Management

Construction sequencing connects site preparation, foundations, framing, rough work and finishes. Inspection hold points need to be respected before work is covered. Discuss access, material deliveries, protection of existing improvements and communication about changes when defining the contract. The final walk and punch list close out the agreed work.

Our ADU Process

  1. Share your address, intended use, photos and available plans.
  2. Review existing conditions, access and the proposed building approach.
  3. Coordinate the required plans, permit responsibilities and construction scope.
  4. Sequence structural work, rough work and required inspections.
  5. Complete finishes, walk the work and address the punch list.

ADU Questions

What is an ADU in California?

An accessory dwelling unit is a separate living unit on a residential property, with its own living, sleeping, cooking and bathroom facilities. Whether a proposed space qualifies and can be approved depends on the property and the applicable review.

How does a garage conversion differ from a detached ADU?

A garage conversion adapts an existing structure. A detached ADU is a separate building. Existing foundations, framing, access and the proposed layout need review before choosing an approach; an existing garage is not automatically ready for residential use.

Do you coordinate permits and plans?

Yes. Our building services include plan submittal, permitting and inspection coordination for work that requires them. Bring any drawings you have so we can discuss the information still needed and define responsibilities in the contract.

What are the typical ADU construction steps?

Start with the intended use and site conditions, review the plans and permit path, define the construction scope, then sequence foundation work, framing, rough work, inspections and finishes according to the approved plans.

Which cities do you serve for ADU projects?

We serve Jurupa Valley, Eastvale, Corona, Norco and Riverside, along with the Inland Empire. Send the project address to discuss the proposed work.
