Custom ADU & Detached Guest House Construction
Expanding your living space and property value across the Sierra Foothills.
Whether you are looking to build a detached guest house for family, create a premium rental income property, or expand your home’s footprint with a structural addition, Nevada County Homeworx (CSLB #1137445) is your start-to-finish partner.
As a Class B Licensed General Contractor, we handle the entire lifecycle of your build—navigating local zoning, managing the permitting red tape, and executing the structural construction with absolute precision.
Full-Service ADU Management
Building an Accessory Dwelling Unit (ADU) in our region requires specialized local knowledge. We manage the headaches so you can focus on the results:
Permitting & Compliance: We handle the complex building departments, setback requirements, and Title 24 energy standards in Nevada and Placer Counties.
Site Logistics & Utilities: From foothill grading and site prep to trenching and tying into septic or sewer systems, we manage the critical groundwork.
Integrated Trade Control: We oversee all mechanical, electrical, structural framing, and plumbing phases under a single point of accountability.
High-End Finish Craftsmanship: We bring our signature finish carpentry and design-focused details to your guest house, matching the architectural style of your primary home.
Designed for Foothill Properties
No two lots in Grass Valley, Auburn, or Meadow Vista are the same. We specialize in building for the unique topography, slopes, and fire-safe building codes (WUI compliance) of the Sierra Foothills.
Our Craftsmanship Guarantee: While every structure starts with engineered concrete and timber, our focus is delivering a seamless, stress-free management process from the day we break ground to the final inspection.
Proudly building ADUs and guest homes in Grass Valley, Nevada City, Penn Valley, Auburn, and Meadow Vista.
