About Cozy ADU
Cozy ADU is a full-service ADU contractor serving the Greater Sacramento area in Northern California. They handle the entire process of adding an accessory dwelling unit or other accessory structures to residential properties — from planning and permitting through to construction. Their service area includes Folsom, Auburn, Roseville, Rocklin, Elk Grove, Placerville, and surrounding communities.
The company positions itself as a turnkey solution, meaning clients hand off the project after key decisions are made and Cozy ADU manages the rest. Their team has a background in residential construction spanning several decades.
What Cozy ADU Builds
As an experienced ADU builder, Cozy ADU works on a range of accessory structures, including:
- Detached accessory dwelling units
- Attached accessory dwelling units
- Garage conversions — both attached and detached
- Backyard offices
- Guest houses and in-law suites
- Tiny homes
- Hobby rooms
As a garage conversion contractor, Cozy ADU can convert an existing permitted garage structure into a livable ADU, provided it meets local county building requirements. They also construct new detached units from the ground up, functioning as a detached ADU builder for clients who want a standalone structure on their property.
Cozy ADU offers floor plan options at different sizes. One example is a 600 sq/ft single-bedroom, single-bathroom layout on a 20' x 30' footprint. Another option is a two-bedroom, one-bathroom layout at 748 sq/ft on a 49' x 16' footprint, featuring high ceilings and an open-concept living area. Both plans are designed to maximize usable space within a compact footprint.
All ADU builds come with a standard set of features, and clients can customize their project to suit their needs and budget. Customizable elements include:
- Cabinet styles and hardware finishes
- Countertop materials (quartz, granite, butcher block)
- Appliance packages and finishes
- Shower and bathroom configurations
- Flooring options including luxury vinyl plank, tile, and carpet
- Interior wall textures and paint
- Lighting and ceiling fans
- Mini-split AC and heating systems
- Exterior siding options including Hardie board, board and batten, and stucco
- Roofing, windows, and exterior doors
- Water heater options including tankless gas and electric heat pump
ADU Planning and Costs
Cozy ADU emphasizes transparent pricing and helps clients understand what to expect when budgeting for an ADU project. Costs vary depending on the scope of the build, local permit fees, and utility hookup requirements. Some key considerations they outline include:
- Impact fees: In Sacramento County, ADUs under 750 sq/ft typically incur no impact fees. Units between 750 and 1,200 sq/ft are subject to proportionate fees based on square footage.
- Size limits: In Sacramento County, attached ADUs are generally limited to 500 sq/ft plus 150 sq/ft for ingress/egress. Detached ADUs can be up to 1,200 sq/ft. Local codes vary by jurisdiction.
- Solar panels: Most newly constructed ADUs are required to include solar panels, though some counties waive this requirement if the primary residence already has solar.
- Rental income: A completed ADU can be rented to long-term tenants (31 days or more), making it a potential source of ongoing rental income and a way to build equity.
Beyond rental income, homeowners often build ADUs to house aging parents, adult children, or simply to add a dedicated backyard office or hobby space. Cozy ADU works with clients to navigate permitting efficiently and avoid unnecessary costs throughout the process.
Their process begins with a free on-site consultation and feasibility assessment, after which they develop a plan tailored to the property and the client's goals. They work exclusively with skilled tradespeople and manage the project from start to finish, delivering a unit that is tenant-ready upon completion.
