Gauntlet Construction: ADU Builder and Design-Build Firm in Roseville, CA
Gauntlet Construction is a family-owned, licensed general contractor based in Roseville, CA, serving the greater Sacramento area including Loomis and surrounding Placer County communities. With over 15 years of experience, they provide residential construction, ADU building, renovation, and commercial construction services across the region.
The company was founded by Tanner Reynolds, who began working in residential construction at age 15. That hands-on background continues to shape how Gauntlet Construction approaches each project — with attention to structural integrity, code compliance, and consistent workmanship. Reynolds remains personally involved in projects to ensure each phase meets the company's standards.
Gauntlet Construction operates with a dedicated in-house crew and established trade professionals, including experienced carpenters, skilled tradesmen, and licensed subcontractors. They do not rely on temporary labor, and every professional on their team is expected to maintain professional jobsite standards on every build.
ADU Construction Services
As an experienced ADU contractor and accessory dwelling unit builder, Gauntlet Construction offers a range of ADU construction options designed to work within existing property configurations and local zoning requirements. Their ADU services include:
- Detached ADU construction — standalone backyard units built to integrate with the primary residence while maximizing usable space and long-term property value
- Attached ADU construction — additions that connect directly to the existing home structure, requiring careful integration with existing foundations, framing, and mechanical systems
- Garage conversion contractor services — converting existing garages into livable ADU spaces, one of the more cost-effective ways to expand a property's footprint
- JADU contractor services — Junior Accessory Dwelling Units built within the existing structure of a home
- Prefab and modular ADU installation — for homeowners seeking faster project timelines, Gauntlet Construction offers turnkey prefab and modular ADU solutions
Each ADU project involves zoning verification, building code compliance, structural engineering coordination, and utility infrastructure management. For detached ADU builds specifically, this includes foundation planning and full utility coordination to ensure the unit meets zoning standards while remaining architecturally compatible with the primary residence.
For attached ADU projects in Roseville, the team also coordinates with HOA architectural guidelines and CC&R provisions where applicable, integrating municipal building regulations and subdivision governance standards into a single construction plan.
Gauntlet Construction operates as a fully integrated ADU design-build firm, centralizing planning, budgeting, permitting, and construction management under one team. This approach is intended to provide scope clarity, cost control, and inspection readiness throughout the project.

- Multi-family, duplex, and townhouse development
