ADU services · California
The right service starts with the project you actually need.
Start with the property and project type, then add design, engineering, permitting, and construction coordination in the order the project requires.
Preliminary online guidance comes first. Final scope, feasibility, price, schedule, and approvals remain property- and contract-specific.
One coordinated service path
From a useful first answer to a finished, inspected home.
01
Understand the property
Available records, geometry, constraints, and verification needs.
02
Define the right project
ADU type, model direction, scope, priorities, and early assumptions.
03
Coordinate delivery
Design, engineering, approvals, site work, construction, and closeout.
Choose the starting scope
Start with the kind of project—not a list of construction trades.
The cards below open the actual service details. Site preparation, utilities, foundation, framing, finishes, and project management are then scoped inside the selected project rather than sold as disconnected steps.
02
Connected addition
Attached ADU
A secondary living space connected to the primary home and coordinated with its structure and utilities.
View service details03
Existing footprint
Garage Conversion
Reuse an existing garage after structure, foundation, egress, utilities, and local requirements are confirmed.

Inside the primary home
Junior ADU (JADU)
Plan a compact unit within the primary home under current property-specific and jurisdiction requirements.
View service details05
Expand living space
Home Addition
Expand the primary home through property-specific design, engineering, utilities, approvals, and construction scope.

Professional project path
ADU Design and Permitting
Coordinate property-specific design, required engineering, documents, applications, responses, and approvals.
View service detailsWork with a constrained site
Options that respond to existing structures, limited yard area, or a specific placement opportunity.
Design around a homeowner goal
Start with who the space is for and how it should support the property over time.
Choose a design direction
Explore a product or finish direction before project-specific adaptation and engineering.
Improve the existing home
Renovation and addition scopes that can stand alone or be coordinated with a larger property project.
Service descriptions are starting points. Property records, local requirements, existing conditions, professional design, engineering, utility review, and the signed scope determine what is actually included.
One coordinated delivery path
Clear responsibility at each decision point.
“End to end” should not mean an unexplained bundle. Each phase needs a purpose, visible outputs, unresolved items, and a decision before the project moves forward.
- 01
Property and scope
What can the site support, and what are we trying to create?
- Preliminary property and record review
- Project type or model direction
- Visible unknowns and professional-review needs
Decision gate: Choose whether to continue, change direction, or request deeper feasibility work. - 02
Design and approvals
What must be documented and confirmed before construction?
- Architecture and engineering coordination
- Permit documents and agency responses
- Selections, assumptions, revisions, and exclusions
Decision gate: Approve the coordinated scope and documents before downstream work is released. - 03
Construction and closeout
How does the approved project become a finished home?
- Site, foundation, frame, enclosure, and interiors
- Utilities, inspections, corrections, and quality checks
- Completion records and project handoff
Decision gate: Complete required inspections and accept the documented finished scope.
The exact contracted scope varies by project. Preliminary online results do not replace a survey, licensed design, engineering, agency approval, trade proposals, or construction documents.
Recommended starting point
I need to know what my property may support.
Start with an address, review the available records and map, make corrections, and test a preliminary model footprint before committing to a service scope.
I need to compare ADU models
Review defined footprints, layouts, images, and model details before testing one on a property.
I need an early planning range
Use explicit baseline assumptions to explore a preliminary project range—not a bid or contract price.
I need to understand the full process
