Practical, Permitted, and Professionally Built

Detached Garages and Sheds of California

More Than Just Storage

Garages and Sheds Designed for California Living

We don’t just drop prefab sheds or cookie-cutter garages into your yard. Every structure is measured, framed, and finished based on your exact goals—whether that’s a secure storage shed, a two-car garage, or a climate-controlled workshop. Our team understands California zoning rules and local HOA considerations. That means your build won’t just look good—it’ll meet all necessary standards. We’ll walk you through size options, roofing types, materials, and finishes that suit your location.

Customized to Fit Your Property

We Build to Match Function, Style & Space

Detached structures need to do more than just stand up—they need to blend in and perform. We match each build to your property lines, design style, and future use. That might mean extra-wide doors, integrated storage lofts, or added outlets for tools and equipment. Whatever you need, we build it right.

From Simple Sheds to Fully Finished Garages

We Handle the Full Project Start to Finish

Every project starts with a site assessment and consultation to determine the best structure for your goals. From there, we handle design, materials, permits, and construction. Our crews are licensed, insured, and experienced in framing, roofing, siding, and trim. Whether you need a prefab shell installed or a full custom build from the ground up, we make it easy. All of our detached garages and sheds come with warranty-backed craftsmanship and long-term reliability.

Quality Materials, Expert Construction

Built for Strength, Function, and Curb Appeal

We use durable materials and trusted construction methods to ensure your detached garage or shed holds up year after year. Pressure-treated lumber, concrete slabs with rebar, galvanized hardware, and impact-rated roofing are just a few of the standards we build into every project. Our experienced crews handle framing, sheathing, doors, trim, and final inspection—so you can trust that your structure isn’t just good-looking, it’s safe and sound.

From Backyard Sheds to Full-Sized Garages

Versatile Builds for Any Use Case

Not every client needs the same structure—and that’s exactly why we offer flexibility in size, design, and function. We build single-car garages, two-bay detached units, tall structures for RVs and boats, and compact garden sheds with shelving and electrical. Need attic storage, windows, or HVAC hookups? We can do that. Whether it’s for tools, toys, or trucks, we tailor every build to fit your exact needs, budget, and lot configuration.
