Hello

I am in the process of finding a builder for a duplex construction in jefferson park area in Denver. Duplex is 5000 sqft and perhaps basement of 1000 sqft. So far, 3 Builders have quoted 12-14% of the cost to build as their fee (+supervision fee ). Two builders have quoted a flat fee of 80-100k for the project (+supervision fee).

I am leaning towards flat fee builders. Tpically, what is the builder fee for this size project?

Thank you 

Interested to learn more on this!......Bump

everybody has to make money. whether it is a % of total job or flat fee, a contractor is gonna make their money. It is standard practice to charge 10-20% of total job for profit and overhead.
