So, you’re thinking about building an ADU in Sacramento. Maybe it’s for your mother-in-law (because it’s time to keep her close, just not too close.), or maybe you’re interested in a stand-alone studio or home office to supercharge your productivity. Here’s the deal: building an ADU isn’t cheap, but it’s also one of the smartest investments you can make. No two ADUs are alike, and factors like size, materials, and whether you’re converting an existing space like a garage or basement or starting fresh, all come into play.

Plus, we’ve worked with clients across every budget and vision to make their dream spaces a reality.
We’re here to break down the numbers, sprinkle in some humor, and give you the inside scoop on what it really takes to build an ADU in Sacramento. Spoiler alert: it’s worth it. Let’s get into the details!
ADU stands for Accessory (or Auxillary) Dwelling Unit, a fancy way of saying “small home on your property.” These are fully functional living spaces with a kitchen, bathroom, and sleeping area. They’re designed to share the same lot as your primary residence and come in three main flavors.
Why are ADUs all the rage in Sacramento? Because they’re a game-changer.
The cost to build an ADU in Sacramento typically ranges from $160,000 to $500,000+. You’re looking at smaller units with standard finishes at the lower end, while larger or more luxurious ADUs push toward the top of the range.
The larger the unit, the higher the cost, thanks to increased material and labor needs. Smaller units under 500 square feet are more affordable but may limit functionality, while larger ADUs can cost more upfront but offer greater flexibility and ROI.
A detached ADU often costs more than an attached ADU because it’s essentially a stand-alone structure with its own foundation and utilities. Attached ADUs can share existing walls and systems, which cuts down on expenses. Garage conversions are typically the most budget-friendly option since the structure is already there.
The materials you choose can swing your budget wildly. Standard finishes like prefab countertops and basic cabinetry will save you money, while custom cabinets and high-end tile can push your price tag up.
A simple, boxy ADU is easier—and cheaper—to build. But if you’re dreaming of vaulted ceilings, custom windows, or intricate rooflines, be prepared to shell out more. Complexity drives both material costs and labor hours.
Running utilities to the ADU is another significant cost factor. Extending plumbing, electrical, and HVAC systems can add thousands to your budget, especially if your property requires upgrades to handle the increased load.
In Sacramento, ADU construction requires navigating local zoning laws and obtaining permits. The ADU permit cost in Sacramento County can run into the thousands, depending on the size and scope of your project. Add inspections and compliance costs to the mix, and it’s easy to see how regulations impact your overall budget.
In Sacramento, where housing demand is high, ADUs can provide a significant return on investment.
Not every return is financial. An ADU can improve your quality of life in countless ways. Here are a few top ways adding an ADU can change how you live.
ADUs are a hot commodity in California, thanks to recent legislation encouraging their construction. Sacramento’s housing crunch makes ADUs an especially smart investment, as more buyers prioritize homes with flexible living options. By building an ADU now, you’re not just keeping up with the trend; you’re ahead of the curve.
The average cost of an ADU in Sacramento falls between $250,000 and $400,000, depending on size and materials. This range typically includes mid-range finishes and standard layouts.
Labor and materials are the largest expenses. Complex designs, high-end finishes, and utility upgrades can also drive up costs. For detached ADUs, new foundations and standalone systems like HVAC often account for a significant portion of the budget.
Sacramento County requires permits for all ADU projects, along with compliance with zoning laws, setbacks, and size limits. Detached ADUs are often limited to 1,200 square feet, and parking requirements may apply depending on your location.
