When should we involve a builder?

Early. Engaging your Custom Home Builder Gilroy during schematic design aligns budget, methods, and lead times before drawings harden.

Do you handle permits and inspections?

Yes—our GC team coordinates permitting, inspections, and closeout documentation for Gilroy New Construction, remodels, and ADUs.

What impacts a Gilroy Kitchen Remodel timeline?

Cabinet and appliance lead times. We front-load selections to protect schedule and sequence trades efficiently.

Are ADUs feasible on my lot?

Often, yes. As an ADU builder in Gilroy, we assess setbacks, utilities, access, and parking to confirm a clear path before design finalization.

Bathroom Remodel Gilroy

A bathroom should feel like a personal spa while performing like a utility space—and our Bathroom Remodel Gilroy services deliver exactly that. At De Mattei Construction, we rethink bathroom layouts to maximize comfort and efficiency, upgrade waterproofing and ventilation systems for long-term durability, and specify premium materials that are both beautiful and built to last.

ADU Builder in Gilroy

Need more space for family, a private home office, or a source of rental income? As a leading ADU Builder in Gilroy, De Mattei Construction specializes in designing and building Accessory Dwelling Units that are both functional and beautiful. We have in-depth knowledge of California ADU regulations and Gilroy’s local permitting requirements, ensuring a smooth and efficient approval process. From compact studio cottages to spacious two-bedroom backyard units, we create ADUs that maximize available square footage while complementing the style of your main home. Our services include zoning and feasibility studies, permit management, and thoughtfully designed layouts with ample storage and natural light. By using durable, low-maintenance materials and efficient construction methods, we deliver ADUs that are built to last, easy to maintain, and tailored to your needs.

Detached vs. Attached ADUs in Gilroy

When planning an ADU in Gilroy, one of the first decisions is whether to build a detached unit or an attached addition to your primary home. Both offer unique benefits, and at De Mattei Construction, we help you determine the best fit based on your property, lifestyle, and goals.

Detached ADUs (also called backyard cottages or granny flats) are stand-alone units built separately from your main house. They offer the greatest privacy and flexibility, making them ideal for rental income, guest housing, or multigenerational living. Detached ADUs often feature full kitchens, baths, and living areas, creating truly independent homes.

Attached ADUs share at least one wall with the primary residence but function as a separate living space, often with their own private entrance. These units are well-suited for homeowners looking to maximize square footage while keeping construction more cost-effective. With thoughtful design, attached ADUs provide independence for family members while maintaining close connection to the main household.

Whether you choose a detached backyard home or an attached suite, our Gilroy ADU builders manage zoning, permitting, design, and construction to ensure your new space is efficient, durable, and seamlessly integrated into your property.
