Cost to Create a Duplex from a Single family
I am looking to possibly create a duplex from an existing single family home. I am wondering if anyone has done something similar and would be willing to share some costs.
I know that there needs to be some specifics to this before providing any type of costs but was hopeing someone could share some ballpark numbers.
I am looking for a legit build from a licensed GC that would be fully permitted.
The following are some specifics about what I would be looking for.
- 1500-2000sf existing split into 2 units that would be 750sf each (say 2 bedroom units) AND SHOULD APPRAISE FOR ABOUT $100K ONCE THE DUPLEX IS COMPLETE
- Demising wall added
- the location is 2 stories so I would need 2 sets of steps on the interior of unit.
- additional kitchen added for other unit
- bathroom added
I know this is extremely general and will be difficult to throw a number at but if I can get some ballpark figures from the BP community, I would really appreciate it.

@Shaun Palmer you may want to ask your zoning/permitting office before trying this. Otherwise, you may actually decrease the value of the property. I think for the cost of doing it right, you could just go buy a duplex.
