Jackson Layne is a licensed ADU contractor in Los Gatos, helping homeowners plan, permit, and build completely custom ADUs. We handle detached and attached ADUs, garage conversions, and JADUs with one team from early planning through construction.
Getting started
An ADU starts with the property. Before drawings begin, we look at the existing home, lot, access, utilities, grading, trees, zoning, and where a new unit can realistically go.
Whether you're considering a detached backyard ADU, an attached ADU, a garage conversion, or a JADU, the right approach depends on the existing conditions and what you want the new unit to accomplish.
From there, we work through the size and layout, structure, utilities, budget, permit requirements, and construction approach. Resolving those decisions early gives everyone a clearer path from initial planning through permit and construction.
Los Gatos ADU requirements can vary by property, site conditions, and project type. We review those constraints at the beginning and coordinate the appropriate drawings, engineering, permitting, and trade input before construction starts.
Tell us about your property, the ADU you're considering, and where you are in the process. We'll help you understand what's possible and the right next step.
(408) 710-1170Typical Scope
Whether we're building a detached ADU, an attached ADU, or converting an existing space, we approach it as a complete home. Kitchens, bathrooms, cabinetry, appliances, surfaces, lighting, and exterior materials are selected around how the unit will be used and how it should fit the property.
Existing-condition review, fixture relocation, wall adjustments, space planning, structural coordination, and constructability review.
Custom and semi-custom cabinetry, countertops, storage, medicine cabinets, mirrors, and hardware.
Water and drain modifications, fixture rough-ins, lighting, outlets, ventilation, controls, and trade coordination.
Shower layouts, pans, drains, waterproofing systems, niches, benches, curbs, glass preparation, and detailing.
Floor and wall tile, stone slabs, layouts, transitions, grout, trim details, substrates, and finishes.
Faucets, toilets, tubs, shower fixtures, glass, lighting, hardware, trim, paint, accessories, and final installation.

The cost of a custom ADU in Los Gatos can vary depending on utility requirements, the size of the structure, and overall scope, including tile, cabinetry, fixtures, and other final material selections. Use the calculator below to estimate a cost range for your project.
End-to-End Planning
The drawings matter, but so do the decisions behind them. We want the property, scope, utilities, structure, selections, permit path, and budget understood early enough to shape the project before construction begins. Working through those details upfront helps expose cost, schedule, and construction issues while they are still easier to solve.
Our Process
As a Los Gatos ADU builder, Jackson Layne manages the project from early planning through construction. We coordinate the designers, engineers, permits, trades, schedule, and field work so you're not piecing together separate teams on your own.

FAQs
Straight answers to common questions we hear from homeowners planning an ADU project.
The main cost drivers are the existing conditions, layout changes, plumbing relocation, shower assembly, cabinetry, tile, fixtures, and overall finish level. Keeping the layout as-is can reduce complexity. Moving drains, changing walls, building a larger shower, adding custom cabinetry, or using specialty materials can move the cost considerably. We establish a realistic planning range after understanding the existing conditions and what you actually want to change.
