ADU Builder Folsom
From home renovations and additions to new construction and commercial projects, Empire Builders brings design, craftsmanship, and project management together under one roof.
Put More of Your Folsom Property to Work
An ADU can solve a very specific housing problem: you need more space, but moving into a larger home doesn’t make sense. Folsom homeowners may be looking for a private space for aging parents, a little independence for adult children, or a long-term rental unit. With ADU construction from Empire Builders, detached units, attached ADUs, and garage conversions can be built around the existing property and how you plan to use it. Call (916) 237-1478 to schedule a no-obligation consultation.

Our Process
01
Determine the ADU Approach
First, we need to know what you're working with. A detached ADU, attached unit, and garage conversion each come with different construction considerations. We'll look at the property and discuss how you want to use the finished space.
02
Establish What's Required
The existing garage, foundation, utilities, available space, and relationship to the main house all affect the project. We'll identify the construction requirements and determine what needs to be addressed before the scope is finalized.
03
Set the Scope and Price
We'll work through the size, layout, materials, finishes, utility work, and other construction details that make up the project. A detailed estimate gives you a clearer idea of the ADU cost before you commit to construction.
04
Get the Project Ready
Plans, permits, inspections, material orders, and other preconstruction requirements are handled before the work starts. Folsom properties can also have specific requirements depending on their location, including additional review in a historic district.
05
Construct the Unit
Construction moves through the work required for the particular ADU. That may include foundation work, framing, roofing, siding, windows, insulation, plumbing, electrical, HVAC, flooring, cabinetry, and finish installation. Your project manager coordinates the trades as the unit takes shape.
06
Inspection and Closeout
Required inspections are completed as the project progresses, followed by the final inspection and a walkthrough of the finished unit. We'll take care of the remaining punch-list details before closing out the project.

Frequently Asked Questions
What types of ADUs can I build in Folsom?
Folsom homeowners may consider detached ADUs, attached ADUs, junior ADUs, and garage conversions, depending on the property and applicable requirements. The existing home, lot, available space, utilities, access, and intended use all factor into which option makes sense.
Can I convert my existing garage into an ADU?
Potentially, yes. A garage conversion can turn an existing garage into additional living space without building an entirely new structure. The existing foundation, framing, ceiling height, utilities, insulation, openings, and other conditions all need to be evaluated before deciding what the conversion will require.
How much does an ADU cost in Folsom?
Size, square footage, site conditions, foundation requirements, utility connections, materials, interior finishes, permits, and whether you’re converting existing space or building new can all affect the final price. We provide detailed estimates based on the actual project rather than promising an arbitrary price per square foot.
Can I use my ADU as a rental?
A long-term rental unit is one reason homeowners choose to build an ADU. Folsom rental demand, the property’s location, the unit’s size and finishes, and local rental conditions can all affect its potential as an income-producing space. If rental income is part of your plan, it’s worth considering that intended use while the project is being planned.
What permits are required for an ADU in Folsom?
ADU construction requires a building permit and must meet applicable California and local requirements. Depending on the property, requirements can involve setbacks, height, parking, utilities, fire safety, and other development standards. Properties in a historic district may also be subject to additional design review or requirements, so the specific property needs to be evaluated before construction begins.
Can an ADU increase my property value?
An ADU adds usable living space and can provide another potential benefit through rental income or housing for family members. The effect on property value varies by home, neighborhood, unit quality, and the local market, so an ADU should be evaluated as a property improvement rather than treated as a guaranteed return.
Can you build an ADU on a single-family home property?
In many cases, yes. The property and existing home still need to meet applicable requirements, and the available ADU options can vary based on the lot, existing structure, utilities, parking, and local regulations. Looking at the property first gives us a much better idea of what’s possible.
