Costs
What if the biggest factor in the cost to build an adu in sacramento isn’t the unit itself, but what your property needs before construction can begin? A detached ADU may cost around $200,000 to $350,000, while a garage conversion may fall around $75,000 to $140,000. Treat these as starting ranges, not estimates for a specific property.

You're likely feeling the weight of this investment while trying to decode California's latest 2026 housing mandates. It's a high-stakes choice that affects your daily privacy and your property’s long-term resale value.
Check your property and see what's possible.
