Custom ADU Builder Stockton
Compare custom scope, site constraints, model options, finish level, construction sequence, and written pricing before selecting a build approach.

We look at your property, goals and local requirements to understand what may be possible.
Consider ADU models and design options tailored to your property and lifestyle.
Develop the design, coordinate permits and prepare for construction around a defined scope.
Property reviews are preliminary. Site feasibility, permitting and final scope require property-specific verification.
Full-service ADU construction
Start with a custom ADU builder or ADU contractor in Stockton, then coordinate design, architecture, engineering, permits, budgeting, construction, inspections, and handoff around the property.
Compare custom scope, site constraints, model options, finish level, construction sequence, and written pricing before selecting a build approach.
Coordinate construction scope, subcontractors, schedule, inspections, site logistics, and closeout around a clearly defined permitted set.
A coordinated design-build workflow keeps property review, design, engineering, permitting, budgeting, procurement, and construction aligned.
Develop the floor plan, exterior direction, material selections, functionality, and site fit before committing to engineering and construction.
Architectural planning can address layout, massing, code constraints, site relationships, and permit drawings where an appropriately licensed professional is required.
Engineering coordination can cover structural, foundation, utility, civil, energy, and other disciplines required by the property and permitting authority.

Official local guidance| Topic | Local guidance |
|---|---|
| City plan eligibility | The City’s preapproved plans cannot be used in FEMA Special Flood Hazard Areas. This restriction concerns the plan program, not a blanket prohibition on ADUs. |
| Energy design | Stockton’s three City designs are all-electric; gas service is not part of those plans. |
| Site review | Planning approval and a site plan showing setbacks and easements remain necessary. |
Selected local requirements, not a complete zoning determination. Confirm the current rules for your address with the responsible agency.
The City drawings are free. Request an itemized building and planning fee estimate plus applicable utility and school charges; free drawings do not mean a free permit.
Stockton ADU application resourcesChoose the custom ADU/JADU checklist BLDG-0103 or the preapproved-plan checklist BLDG-0079. Vendor plans also require authorization from the plan owner and the applicable energy documents.
