What Our Clients Say
We are very pleased with our new 1200 sq ft ADU that Dan and his team have built for us. Dan was always very quick to respond whenever we had questions, and his staff’s flexibility on any changes and/or issues that came up were addressed in a timely manner.
DLC built an 800 sq ft addition to our home. It included a bedroom, a hall bathroom, and a large master suite with a luxurious bathroom and custom walk- in closet. It came out beautiful, exactly how we wanted it, and in a very efficient timeline.
We found DLC on Instagram and exceeded every expectation. Dan and his team delivered a truly custom, designer-level build. His engineering background showed in every recommendation. Communication was clear, timelines and costs were accurate, and the final result was outstanding. Highly recommended.
Dan and his team converted our 1940 garage into a beautiful ADU after previously renovating our bathroom and pantry. Their bid was competitive, the craftsmanship excellent, and they consistently go above and beyond. After many renovations with other contractors, they are among the very best.

Common Questions About Our Services
An ADU (Accessory Dwelling Unit) is a second living space on your property—often called a
granny flat, casita, in-law unit, or pool house. To qualify as an ADU, the space must include:
- A functioning kitchen
- A bedroom with a closet
- A full bathroom with a toilet and shower
In California, ADUs can be up to 1,200 sq ft and may be attached or detached. ADUs have
exploded in popularity because new laws made them easier to build, and they’re a smart way to
add space, increase home value, and create long-term flexibility.
Here are all the reasons our clients have chosen to build ADUs, with typical Sacramento costs:
- Expand your family ($150k to $400k for new build or conversion).
- Take care of aging family members ($105k to $300k garage conversion).
- Increase your home's value (up to 20-30% ROI via equity boost).
- Have an extra space for visiting friends and family ($250k to $500k detached).
- Have a healthy rental income stream ($1,800 to $2,000/mo).
- Utilize your detached garage for more than just storage ($105k to $300k conversion).
A home addition is a construction project that adds new square footage to your existing home. This can include a new bedroom, expanded living room, larger kitchen, primary suite, or even a second story. A well-designed addition should match your home’s style and feel like it was always part of the original layout.
Here are the biggest tips we’ve learned from successful addition projects:
- Plan the layout first — square footage matters, but flow matters more.
- Match the roofline and exterior finishes — this is what makes an addition look
seamless. - Keep plumbing efficient — bathrooms and laundry additions cost more when utilities have to move far.
- Decide your finish level early — cabinets, tile, flooring, and fixtures shift the budget fast.
- Expect permits + inspections — build time is only part of the timeline.
The smoothest projects are the ones where decisions are made early and the scope stays clear.
Yes—many homeowners treat a garage conversion as a type of home addition because it adds usable living space to the home. The difference is that the slab and structure often already exist, which can reduce build time and cost. D. Loesch Construction can help you compare a garage conversion addition vs a traditional addition based on your layout, budget, and goals.
An ADU garage conversion transforms your underused garage into a fully functional living space—perfect for rental income, multigenerational living, or expanding your lifestyle
without moving. It’s often the most cost-effective way to build an ADU because the slab and structure often already exist.
In many cases, yes. The biggest factors are the condition of the slab and framing, ceiling height, and whether the space can meet current building code and energy requirements. A garage conversion contractor like D. Loesch Construction can evaluate your garage and confirm what’s realistic.
Yes—garage conversions are often one of the best ROI-friendly ways to create a rental-ready ADU. Rental income depends on layout, privacy, parking, finish level, and the local rental market.
