Question 1

How much does it cost to hire a general contractor to manage subcontractors?

Accepted Answer

National baseline, before Portland adjustments: Usually 10–20% of the construction cost (This Old House; Bob Vila; SVN Builder). On a $60,000 project that is $6,000–$12,000. Small or complicated jobs land near the top; large, simple ones near the bottom.

Question 2

What is the difference between a contractor’s fee and markup?

Accepted Answer

The fee is what the contractor keeps for overhead and profit. Markup is how it gets charged in a fixed-price bid: added onto sub prices and materials, often 10–20% in total (Baldwin Builders). In a cost-plus contract the fee is a separate line on top of actual costs.

Question 3

Is cost-plus or fixed price better for me?

Accepted Answer

Fixed price gives you a known total when the drawings are complete. Cost-plus fits remodels with unknowns behind the walls, but you carry the overrun risk. If you choose cost-plus, ask for a fixed fee or a not-to-exceed cap.

Question 4

Can I just pay someone to find good subcontractors?

Accepted Answer

National baseline, before Portland adjustments: Yes. Owner’s representatives and consultants do this for about $75–$300 an hour (Inventure Properties; Terrapin, 2026). We estimate 3–6 hours per trade. You then hire, pay and schedule each trade yourself.

Question 5

Do some contractors charge more than 20%?

Accepted Answer

Some do, especially on small or complicated jobs where the management work doesn’t shrink with the budget. Builders describe cost-plus fees of 15–20% (Baldwin Builders). If a quote is above 20%, ask what it covers.
