Development units per acre

[Ricky Armstead]

Hello BP I'm looking at possibly doing my first development. I been sitting here trying to calculate how many multi-family units can I put on the lot. I can’t seem to figure the math needed for this.

The Lot size I’m looking to purchase is:
0.20 acres
8,712 square feet

City Building Density Codes:
* Twelve dwelling units per acre and mixed use structures with commercial uses on the first floor.
* Eight multifamily dwelling units per acre.
* Eight single-family dwelling units per acre.

I believe an acre of land is 43,560 square feet? BP how would I figure this equation?

Lol should have paid more attention in math class.
