How much does it cost to build an ADU in Sacramento in 2025?

If you’re thinking about building an Accessory Dwelling Unit (ADU) in Sacramento, one of the first questions you’ll have is: How much will it cost?

At Result Construction, we believe in transparency. Costs depend on size, design, and finishes, but here’s what you can expect in 2025.

Average Cost of an ADU in Sacramento

• Garage Conversion ADU: $90,000 – $120,000

• One-Bedroom Detached ADU (400–600 sq. ft.): $140,000 – $180,000

• Larger Detached ADU (700–1,200 sq. ft.): $190,000 – $300,000+

What Factors Affect the Price?

1. Size & Layout – Bigger units naturally cost more.

2. Type of Construction – Garage conversions are less expensive than new detached ADUs.

3. Finishes & Upgrades – Luxury flooring, upgraded appliances, and custom designs increase costs.

4. Permitting Fees – Sacramento permit fees vary but are factored into our estimates.

Example: A $150,000 ADU

A 500-square-foot detached ADU with one bedroom, kitchen, and bathroom typically costs around $150,000.

• With financing support from our partner brokers, monthly payments could be as low as $1,200–$1,400.

• Renting the unit could generate $1,800–$2,200/month, making it a profitable investment.
