MORE ROOM FOR WHAT COMES NEXT
Make room for the next chapter without leaving your property.
An ADU creates independent space for family, frequent guests, focused work, caregiving, or future rental use where local rules allow.
The right solution should meet today’s need without limiting how the property can work tomorrow.
Create a private home for family, a guest house, a dedicated workspace, or a future income-producing dwelling—planned to stay useful as your household and property needs evolve.
ADU OPTIONS
The right ADU starts with the right fit.
Lot conditions, existing structures, access, utilities, and intended use all influence which ADU approach makes sense. Explore the options below, then begin with a property-specific feasibility review.
START WITH THE PROPERTY
Know what your property can support before you commit.
An ADU is more than a floor plan. Architecture, engineering, utilities, drainage, energy requirements, fire safety, permits, site access, and construction logistics all affect one another. Builtech reviews the property as a complete system before recommending a direction.
Lot + standards
Setbacks, coverage, easements, trees, and protected areas.
Utilities
Site conditions
Access + logistics
DESIGN THROUGH CLOSEOUT
A coordinated path from possibility to closeout.
Each stage has a defined decision, deliverable, and owner responsibility so feasibility, design, permitting, pricing, and construction remain aligned.
01
Feasibility
Review the property, applicable requirements, intended use, early budget, and project constraints.
02
Concept Design
Test placement, layout, access, massing, privacy, materials, and the relationship to the existing property.
03
Engineering + Permits
Coordinate architecture, structure, energy, utilities, fire, and site documents for agency review.
04
Preconstruction
Finalize scope, selections, schedule, budget, site logistics, procurement, and permit conditions.
05
Construction + Inspections
Manage site work, trades, quality control, communication, required inspections, and changes.
06
Closeout
Complete final inspections, punch work, documentation, systems review, and owner handoff.
PROJECT-SPECIFIC BUILDING SYSTEMS
Choose the construction system the project actually needs.
No single building system is right for every ADU. We evaluate structure, site access, energy performance, fire exposure, maintenance, installed cost, and schedule before recommending an approach.
A useful budget starts with a defined project.
Headline price-per-square-foot figures rarely account for site work, utilities, structural conditions, access, finishes, permits, or the selected building system. We budget around the property-specific scope.
ADU FAQ
Questions to answer before design begins.
Clear expectations around cost, approvals, conversion feasibility, rental use, and building performance make early decisions more useful.
How much does an ADU cost?
Can any garage be converted into an ADU?
Can I rent the completed ADU?
Will I need to replace converted garage parking?
Can an ADU be fireproof?
Can a home office become a rental later?
