Explore the feel of the bedrooms, living space, kitchen, and bathrooms in this furnished concept. The catalog planning footprint is 25 × 30 ft; the illustration is not to scale. Final room geometry and architecture are developed after setbacks, access, utilities, structure, privacy, and owner priorities are confirmed.

Model area: 750 sq ft
Planning footprint: 25 × 30 ft

Furnished planning concept — not to scale or for construction. The model area and planning footprint shown are catalog targets. Final room geometry, doors, windows, furnishings, and dimensions are confirmed through property-specific design and professional review.

Buildable rectangle

Confirm that the property can support the 25 × 30 ft building footprint after applicable setbacks, easements, lot coverage, separation, and site constraints are reviewed.

Construction access

Verify delivery, staging, excavation, concrete, framing, and equipment access before treating the concept price as project-specific.

Utilities

Locate and evaluate electrical service, sewer, water, gas or electrification strategy, and any utility upgrades or trenching required for the proposed placement.

Local approval path

Confirm the jurisdiction, current ADU standards, submittal requirements, agency review path, and any property-specific fire, drainage, tree, geologic, or survey requirements.

Property qualification

Use the actual address before choosing the final model.

Specifications & selections

Know the model. Define the details.

Flex 750 is a starting point for your project. The catalog defines its planning size and room counts; the specifications below show what is resolved with your property and written proposal.

Structure: Steel-frame design direction. Member sizes, connections and lateral design require project-specific engineering.
Foundation: Foundation type and dimensions are selected after site and soil review.
Roof & exterior: The gallery shows the architectural direction. Roofing, cladding, colors and opening schedules are selected during design.
Kitchen: Cabinet layout, countertops, appliance models and allowances are established in the written scope.
Bathrooms: Fixture models, tile, waterproofing and accessibility choices are confirmed with the final layout.
Interior finishes: Flooring, paint, doors, trim and hardware selections are documented before construction pricing is finalized.
Heating, cooling & hot water: Equipment type, capacity and location require energy design and utility review.
Electrical, water & sewer: Connection locations, service capacity, trenching and upgrade requirements are property-specific.
Laundry & storage: Location, appliance clearances and storage requirements are resolved with the room plan.
Height & ceiling dimensions: Not established by the catalog footprint; confirmed in the architectural elevations and sections.

Budget transparency

What the planning budget covers.

These allowances use the same ADU California Inc. calculator as the total above. They assume standard finishes and steel framing, with no address, site-condition adders or utility upgrades selected. They are not a fixed-price inclusion list.

Building constructionSteel framing and standard-finish assumptions in the planning calculator.: $288,500 – $387,000
Site-work allowanceBaseline allowance; no slope, demolition or tight-access adjustments selected.: $14,500 – $19,500
Design & engineering allowancePlanning allowance, not a professional-services quote.: $26,000 – $35,000
Permit & agency fee allowanceNo city selected. Confirm actual charges with the responsible agencies.: $20,000 – $27,000
Contingency allowanceA planning reserve; not a guarantee against cost changes.: $35,000 – $47,000
Utility upgradesNo upgrade allowance selected. This does not mean connections or upgrades are free.: Not assessed
Total preliminary project range: $384,000 – $515,500

Resolve before approving your proposal

Utility connections and upgrades, demolition, grading, drainage, retaining walls, access, fire requirements, solar, surveys, specialty reports, landscaping, decks, furniture, financing costs and owner-selected upgrades must be reviewed separately. Your signed scope identifies actual inclusions, exclusions and allowances.

Before you choose

Questions about Flex 750.

Will this model fit my backyard?

Start with the 25 × 30 ft planning footprint. The property review must also account for setbacks, easements, building separation, access, utilities and other site constraints. The footprint alone does not establish eligibility.

Can I change the layout or finishes?

Discuss your room arrangement, window orientation, kitchen, bathroom and finish preferences during design. Changes can affect the footprint, engineering, cost and approval path.

Are the pictures and layout construction drawings?

No. Images illustrate a design direction and the schematic is for planning discussions. Construction requires coordinated project-specific documents and approvals.

Is the displayed budget a turnkey quote?

No. It is a preliminary calculator range with the assumptions and allowances shown above. A written proposal follows property, scope, utility and design review.

What should I send to get started?

Provide the property address, intended use, preferred model and any existing survey, site plan or utility information. You can begin even if those documents are not yet available.

Property-specific next step

Test the 25 × 30 ft footprint before choosing the final scope.

The result is preliminary and must be verified against source data, local rules, site conditions, and professional review.
