Our Client Testimonials
We needed our kitchen updated before hosting family for the holidays, and LeCut Construction delivered right on schedule. The initial bid was transparent with zero hidden fees added along the way. They knocked out the tile backsplash, custom cabinetry, and island installation in under three weeks. Having a clear daily timeline made working from home during construction surprisingly easy.
Lecut built our outdoor kitchen in Saratoga just in time for our family reunion. No hidden fees, great work, and completely hassle-free.
We needed a ground-floor room addition in Almaden Valley for my aging mother. Lecut gave us a clear, itemized quote upfront with no surprise fees. The project manager kept us informed every morning, and the new space passed city inspection on the very first try.
With kids growing up, we desperately needed a playroom, so we booked Lecut for a garage conversion in Willow Glen. They started three days after our initial call, kept to the exact quote without hidden costs, and wrapped up early.
Lecut replaced our worn hardwoods in Los Gatos in two days for the exact upfront price quoted.
Building a detached ADU in Cupertino was seamless with Lecut handling all permits and construction. Their strict schedule meant I had a tenant paying rent two weeks earlier than projected.
Booking our kitchen remodeling consultation online took under two minutes. The crew showed up at 8 AM sharp in Sunnyvale, stuck to the itemized estimate down to the penny, and finished the installation ahead of deadline.
Adding a second story addition to our Santa Clara home felt risky until we signed with Lecut. They locked in our contract price before breaking ground, eliminating cost overruns. Their crew worked efficiently, completing structural framing ahead of schedule while keeping the job site spotless.
How We Take An ADU From Plan To Construction
Look At The Property First
Before deciding on the size or layout, we look at the space available on your lot. Access, existing structures, and the location of utilities can all affect where an ADU will fit.
Work Out The Design
We discuss how you intend to use the unit, then plan the rooms around those needs. A rental unit may call for a different arrangement from a small home for a parent or adult child.
Prepare For The Building Work
The design needs to account for local requirements, site conditions, and the practical details of construction. These items should be addressed before work moves ahead.
Build And Review The Details
Once the project is ready to proceed, construction follows the agreed scope and plans. We pay attention to the fit of materials, fixtures, and other finishing details before the work is complete.
More Living Space Without Leaving Your Home
Moving isn’t always the right answer once a house starts feeling crowded. An adult child might need a place of their own. An older parent might want to live close by without sharing a roof. A growing household might just need another room and bathroom. Sometimes the extra space you’re after can get built right where you already live.
LeCut Construction provides accessory dwelling unit services in San Jose for homeowners looking to make better use of their property. The first question is how the new unit will fit into everyday life. Who will live there? Will they need a separate entrance? How much privacy should there be between the main house and the new space?
These answers affect the ADU design and planning from the start. We consider the property’s existing conditions alongside your plans for the additional space.
What Could An ADU Add To Your Property?
Any family keeps changing over time, so do their needs too. That’s quite common; many homeowners often consider an ADU for reasons such as:
- Giving parents or adult children a more independent place to live
- Creating a separate home for long-term guests
- Making room for rental use, subject to applicable requirements
- Adding a living area without changing the main house as much
- Making better use of an underused section of the property

Which Type Of Accessory Dwelling Unit Fits Your Property?
Your lot and what you actually plan to use the unit for go a long way toward narrowing down the right ADU type. A detached unit stands apart from the main house, giving each household genuinely more separation, but it needs enough usable outdoor space and a practical way in and out. An attached ADU shares a wall with the home, which can work well on properties where a fully separate structure just doesn’t fit. A garage conversion takes yet another route, reworking something that’s already there, though its existing condition and layout limit what’s actually possible.
If a detached ADU in San Jose is what you’re weighing, look past the floor plan itself. Think about how people will actually come and go, which direction the windows face, and how much outdoor space is left once construction wraps up.
What Needs Checking Before You Build?
Not every part of a lot is fit for building on. A narrow yard, sloped ground, mature trees, utility lines, or tight equipment access can all shape the design long before anyone breaks ground.
Local zoning and building requirements factor in heavily too. Setbacks, size limits, and permit requirements can all influence what’s actually possible on your property. Checking these details early keeps a design from moving too far along before a real problem shows up.
Solid site planning and zoning review takes the property as it genuinely stands, rather than trying to force some preferred layout onto a space that just won’t accommodate it. These early checks set a realistic direction for the whole project and give you a much clearer sense of what the work actually involves.
How Do You Make A Small ADU Feel Comfortable?
A small ADU works a lot better once its layout stops wasting space. The kitchen needs real counter space to function. The bathroom needs enough room to actually move around in. Everyday items need somewhere to go besides the floor or the counter.
Windows bring natural light into the living space, while solid ventilation keeps moisture and stale air from becoming a problem. Privacy deserves real thought too. Worth considering the sightlines from the main house, nearby outdoor seating, and exactly where the unit’s entrance sits.
You don’t need expensive finishes tucked into every corner. A practical layout, sensible storage, and durable, low-maintenance construction usually do more for livability in a compact unit than anything decorative ever could.
How Should You Plan For Future Use?
An ADU might house a parent today and serve a totally different purpose a few years down the road. Worth thinking through before the layout gets locked in. Does the unit need its own entrance? Extra storage? Room for a full kitchen, or enough independence for someone to genuinely live on their own in it?
Rental use might be on the table too, depending on local requirements. In that case, privacy and everyday convenience matter even more than usual. The entrance, windows, and outdoor areas all need to work for whoever’s living there, without creating constant disruption for the main household.
Why Work With Us For ADU Construction?
LeCut Construction handles design-build work, construction, project management, and other home improvements under one roof. That background supports a connected process from the earliest planning straight through the actual building phase. As an ADU contractor in San Jose, we think through intended use, site conditions, and finishing details, not just the structure itself in isolation.
Whether you’re planning space for a family member or considering a separate unit for rental income, the design needs to genuinely suit both the property and the people who’ll actually live there. A well-planned addition should feel like a real, useful part of your home, not something dropped into the backyard as an afterthought.

People Also Ask
The cheapest option for an Accessory Dwelling Unit (ADU) is typically a prefabricated or "prefab" unit, often referred to as a modular or panelized system. These are built off-site in a factory, which reduces labor costs and construction time compared to a fully custom, stick-built ADU. A studio or one-bedroom layout with a simple, open floor plan will also keep costs down. For homeowners in San Jose, Santa Clara, and Sunnyvale, it is essential to factor in local permit fees and site preparation. At LeCut Construction, we recommend comparing prefab kits with a small, detached garage conversion, as this can sometimes be the most budget-friendly path for your property.
For homeowners in San Jose, Santa Clara, and Sunnyvale, developing Accessory Dwelling Unit plans requires careful consideration of local zoning laws and building codes. A well-designed ADU plan should prioritize efficient use of space, natural light, and privacy for both the main house and the new unit. It is essential to work with an architect or designer familiar with California's specific ADU regulations, including setback requirements and parking exemptions. LeCut Construction recommends starting with a site analysis to determine the best location for your unit, whether attached, detached, or a garage conversion.
