Our Client Testimonials
The best ability is availability. I originally chose LeCut after interviewing with a few local Referred construction people. My decision was based on, simply looking at the yelp and Google reviews first. Then, Yari, who became our consultant, showed up and spent some time discussing the project with me. We set realistic goals for a timeline. He shared some ideas that the other construction team members did not share. I didn't feel like I was surprised during any point in the process. One of the things that Yari did really well is maintain communication and pretty much a daily basis. There was times when he was proactive, but there was times when he was responsive to my calls. Doing a big construction project has a lot of small intricacies. I felt like the communication was pretty fluid throughout. This was even when Yari was on a family vacation up in Yellowstone. He was proactively communicating with me. Edgar was our foreman and he did an excellent job of showing up every day and working on rhythm. I don't think he took a day off. Overall, I would say very professional between my two point people. The owner of the company, Michael showed up and did a friendly check in when Yari was on vacation. Overall, we are happy with our new kitchen and living room floors. Thank you guys! Keep up the great work...

We finally brought down our master bathroom and started from scratch. The old layout had the toilet right next to the tub which was just weird.

San Jose is a mix of neighborhoods, ranging in space and time, including the old houses of Willow Glen near the historic Winchester Mystery House, up to the thick residential blocks of the Downtown area around Plaza de César Chávez, with the sun-exposed space of South San Jose close to Santana Row. Long summer heat, periods of inland raininess and cooler winter nights are the local climate which can be a challenge to detached structures unless well thought out. Small units are prone to overheating and moisture imbalance particularly when airflow and insulation become thought of as secondary considerations instead of design elements.
We provide Detached ADU Services in San Jose by designing to work under real conditions. Our team does not use mechanical systems only to regulate the heat gain. On moderate levels and humidity, our team molds layouts, building assemblies, and exterior exposure to control heat gain and humidity. The planning of strategic orientation, material layering, and ventilation contribute to ensuring a steady inside environment whether in summer or in winter. This brings about disengaged ADUs that are comfortable in high temperatures and dusty seasons and reliable with long usage.
New Living Unit Building
The development of new living units should be well coordinated in terms of structure, environment and available areas of residential space. Our group starts by analyzing the interaction of the new unit to the primary property and the conditions around them.
Site-Specific Construction Planning
We evaluate the access points, sun exposure and available space to make informed decisions at the beginning of the construction process. The initial planning done at this phase assists in avoiding layout clashes, assists in efficient staging of material and assists in the smooth running of the build.
Performance-Focused Construction Methods
The choice of construction methods is determined to resist the long warm seasons and change of temperature in San Jose. The various insulation, exterior material, and roof assembly are synchronized in order to restrict thermal stress and control effective heat transfer. Such practices promote the sustainability of durability as well as comfortable interiors between seasons.
Organized Construction Management
Construction is controlled and gradual as our group takes care of sequencing, inspections, and quality checks to ensure the construction is steady and in control. The thoroughness of all steps will minimize the occurrence of rework and unreliability of made changes, as well as ensure high quality of assembled products.

- Balanced Space Organization: Spaces within the interiors are designed to accommodate the everyday activities. This enhances usability in small areas. Zoning gives privacy.
- Heat and Airflow Awareness: Layouts are designed in a manner that minimizes heat build up. Where feasible natural ventilation is promoted. There is a balanced state of indoor conditions.
- Long-Term Flexibility: Space is geared to change with time. Layouts facilitate need changes. The plan is designed to be long term.
Considerate extensions are more effective when they are derived through actual usage patterns and place behavior and not presumptions or conventional design approaches.

While San Jose offers many opportunities, some residents are relocating due to the exceptionally high cost of living, particularly housing prices and rent. The city's traffic congestion and long commute times also push people to seek more affordable or spacious areas. For homeowners, property taxes and maintenance costs can be burdensome. However, for those who choose to stay or invest in the area, working with a trusted partner like Lecut Construction can help maximize a property's value through strategic remodeling. Ultimately, the decision to move is personal, balancing career prospects in Silicon Valley against lifestyle and financial priorities.
For properties in San Jose, the maximum size of an attached Accessory Dwelling Unit (ADU) is generally limited to 50% of the existing primary dwelling's square footage, up to a cap of 1,000 square feet. This rule applies to most single-family residential zones. However, if the primary home is smaller, the ADU can still be built up to 800 square feet, provided it meets all setback and height requirements. For a detailed breakdown of these regulations, including specific lot coverage rules and exceptions for larger lots, please refer to our internal article titled Attached ADU Services in San Jose. Lecut Construction recommends always verifying current city codes before finalizing your design.
The impact fee for an Accessory Dwelling Unit (ADU) in San Jose varies based on the square footage of the unit and the specific fee schedule set by the city. As of 2026, fees typically range from a few thousand dollars to over $15,000 for larger units. It is important to note that these fees are separate from building permit costs and can include school, park, and transportation impact fees. For the most accurate and up-to-date figures, homeowners should review the official San Jose fee schedule or consult a professional.
