Adding a an ADU to a small house.
Hi, if one was to add a second unit to a small home and convert it to a duplex. Let’s say the addition was 900 square feet. Any estimated range of how much this would cost? Thank you in advance!

Location specific, in California numbers like $250k are tossed about as a ballpark.
Note: SFR + ADU does not a duplex make. Until about a month ago, SFR+ADU was financed identically to a SFR, and duplex was it's own category. Now the rules are a little more lax, SFR, SFR+ADU, and duplex, are 3 distinct categories.
