Calculate the cost of building an accessory dwelling unit
BEGINWhat type of unit to build?
Studio, 400 ft², garage conversion
Studio, 400 ft², detached new construction
1 bedroom, 600 ft², detached new construction
2 bedroom, 750 ft², detached new construction
3 bedroom, 900 ft², detached new construction
3 bedroom, 1200 ft², detached new construction
Include separate water and gas?
If you plan to rent out your ADU, you may want the utilities on separate meters, so your tenant's utility bills will be separate from yours.
NEXTIs home located on hillside?
Construction on slopes or hillside requires additional design and site prep work, like grading the surface or providing additional support for the structure. be separate from yours.

We estimate that your project will cost with a likely range of
Below is a detailed breakdown of this estimate. You can change the ADU details to see how the estimate changes.
