Building an ADU doesn't have to be complicated. We understand that adding a new dwelling is a big decision—whether it's for rental income, housing a family member, or a dedicated home office. At Leon Construction, we make the process predictable, efficient, and stress-free.

We offer high-quality construction for all ADU types, including Detached New Construction, Garage Conversions, Junior ADUs (JADUs), and Above-Garage Additions. Our key advantage is speed and compliance: we have a library of pre-approved ADU plans that have already successfully navigated the permitting process across various California zones and city jurisdictions.

Every unit benefits from our core structural expertise, ensuring a safe, durable investment. We deliver the complete solution: from initial site assessment and design through permitting, foundational concrete, structural framing, and final inspection, maximizing your property's value while strictly adhering to all local codes.

The Design-Build approach is the most efficient, streamlined path to project completion. By integrating the design, engineering, and construction phases under a single contract, we become your one point of contact, taking complete responsibility for the entire project outcome.

This integrated system eliminates communication gaps, reduces project timelines, and allows us to provide accurate, transparent cost forecasting early in the process.

Our expertise manages the complexity for you:

Design and Planning: While we often handle engineering with our in-house team, we maintain a strong network of professional partners, including AIA-accredited architects, ensuring the best possible design and compliance.

Structural Integration: Leveraging our deep structural knowledge, we value-engineer and construct the most critical elements (foundations, load-bearing walls) efficiently.

Project Flexibility: We engage at any phase—from pre-construction consulting and permitting all the way through to mid-project takeover or full-scope contracting.

We are specialized structural contractors focused solely on the integrity, safety, and longevity of your build. Our services go far beyond standard framing, providing meticulous execution of the most critical load-bearing systems.

We specialize in building and repairing all primary load-bearing elements from the ground up:

Foundations & Concrete: Footings, concrete slabs, and critical concrete work.

Vertical Systems: Load-bearing walls, columns, beams, and girders.

Roof Systems: Complex roof trusses and rafters.

Lateral Load Resisting Systems (LLRS): Expert construction of shear walls, moment frames, and bracing systems required to resist wind and seismic forces.

We are highly proficient in all aspects of structural connections, including certified Simpson Strong-Tie installation and specialized hardware placement. Whether you need framing repairs, seismic retrofitting, or construction of a new, complex structure, we are the experts engineers and architects trust to build it right, to code, and to last.

Winery construction requires a highly specialized blend of industrial function, premium hospitality design, and structural expertise. We build facilities designed to support your brand, optimize production flow, and deliver an exceptional visitor experience.

Our scope covers the full facility lifecycle, from initial site development and grading to final installation. We specialize in building both the utilitarian and the public-facing areas, including: energy-efficient barrel cellars and storage facilities, structurally complex crush pad and production areas, elegant tasting rooms and commercial kitchens, and precise utility routing and infrastructure necessary for modern winemaking equipment.

We ensure your facility is structurally sound (leveraging our deep expertise in concrete and specialized framing), aesthetically resonant, and perfectly tuned to meet critical operational demands.
