Sacramento's Premier Home Remodeling Company
If you’re a Sacramento area homeowner looking to add more living space to your existing property, you may have been thinking about building an ADU. The overall price of an ADU will vary, depending on the size of the building, the type of ADU, the quality of building materials, and the finishes and amenities included. We’ve compiled a quick guide to help explain what an ADU is, why you might decide to build one, and how much it might cost.
Accessory Dwelling Units (ADUs) are living spaces that are separate from your main house that can be used for a variety of purposes. An ADU can be detached (most common) or attached (like a garage conversion). To be considered an ADU, the structure must be insulated, have plumbing and electrical wiring and have a bedroom, and a half or full bathroom. These dwelling units can be used to house family members, utilized as office space or an entertainment room, or even rented out to tenants. California homeowners often choose to build ADUs because they don’t require the purchase of additional land and the extra bedrooms and bathrooms are added to the overall appraised value of their property.
ADUs in Sacramento can cost between $150,000 to $450,000 with an average of $300,000. The total cost depends on the size of the ADU and the quality of building materials and finishes. The prices for ADUs in the Sacramento area are the following:
The price ranges can be affected by a variety of factors, including the following.
Architecture and design can cost between $6,000 to $14,000 depending on the complexity of the design. Custom designed ADUs may cost more than a basic ADU.
Land survey fees can cost between $500 and $1,500 to mark property boundaries and avoid disputes with neighbors.
ADUs between 300 and 749 square feet have a building permit and plan review fee that is up to $1,780. An ADU in Sacramento 749 sq ft and below will cost up to $4,800 in permits and fees.
For Sacramento ADUs 750 to 1200 square feet, the building permit and plan review fees are up to $2,500. ADUs 750 square feet and above are also assessed Park, Flood, Transportation, and School Impact fees between $4,800 and $6,000. The total estimated fees for ADUs this size will be somewhere between $10,000 and $14,200.
| Permit / Fees | 300 to 749 sq ft | 750 to 1,200 sq ft |
|---|---|---|
| Building Permit + Plan Review | Up to $1,780 | Up to $2,500 |
| Fire & Planning Inspections | Included | Included |
| Public Works, Tech, Recycling | Included | Included |
| Park, Flood & Transportation Fees | $0 | $4,800 to $6,000 |
| Estimated Total Fees | Up to $4,800 | $10,000 to $14,200 |
The overall size of the ADU will be a factor in the final cost. Larger floor plans generally cost more than smaller ADUs. An ADU that is smaller than 500 sq ft may cost less but offer less functionality. Larger ADUs offer more flexibility and living space but cost more.
A detached ADU is a separate building on your property which requires plumbing and electrical. Detached ADUs must have the required setback to be compliant with local zoning regulations.
An attached ADU, which is an addition to your home, is typically cheaper than a detached ADU. A finished basement is a type of attached ADU. Garage conversions are generally the least expensive type of ADU.
Ensuring the site has proper drainage, level ground, and foundational support may add to the cost of the ADU.
Adding electrical, plumbing, sewer, and HVAC systems can add thousands to the overall cost of the ADU project. Depending on the city, electrical panel upgrades may be required for construction.
Basic materials like pre-fabricated countertops and cabinets can keep ADU costs to about $200 per square foot, while luxury materials like hardwood flooring and natural stone countertops can bring the price point to $400-500 per sq. ft.

There are multiple, sometimes overlapping reasons why Sacramento homeowners choose to invest in building an ADU.
The extra square footage, bedrooms, and bathrooms in an ADU are added to the overall appraisal value of your home and property. This can raise the resale value of your home. Some homeowners also build an ADU to rent it out to tenants. This can help produce extra monthly income.
Many families build an ADU to house other family members and give them a place to live where they have autonomy. An ADU can also be used as a home office, an entertainment room, or a guest room for visitors or out-of-town family.
Building an ADU in Sacramento is less expensive than in larger cities. Price ranges in San Diego are about 10% higher than in Sacramento, Los Angeles ADUs are about 20% more expensive, and it costs up to 40% more to build an ADU in the San Francisco Bay Area than Sacramento.
