Builder Fee, Margin & Pricing Transparency for Charlotte Custom Homes

Builder pricing models are the most opaque part of custom home building, and the opacity is intentional in much of the industry. Families typically learn how their builder makes money only after the contract is signed — and frequently only after a dispute. This page explains the actual pricing landscape in Charlotte luxury custom building so families can ask the right questions during interviews.

Three pricing models dominate the Charlotte luxury market: fixed price (also called lump sum or stipulated sum), cost-plus with a percentage fee, and cost-plus with a fixed management fee. Each one creates different incentives for the builder. None of them is inherently bad; the question is whether the model fits the family's risk tolerance and whether the contract reflects the model honestly.

Our Approach

Fixed price means the builder commits to a total contract amount before construction begins. The builder absorbs cost overruns; the family absorbs the cost of any change orders. Fixed price requires complete plans and complete selections at contract signing — without them, the builder must build hidden contingency into the price (typically 8-15%) to protect against unknowns. The family pays for that contingency whether or not it is consumed.

Cost-plus with a percentage fee means the family pays the actual cost of construction plus a builder fee calculated as a percentage of cost (commonly 15-25%). The builder has no exposure to cost overruns; the family carries them. The percentage structure also creates a structural conflict of interest — every cost increase increases the builder's fee. Many families prefer to avoid this model for that reason alone.

Cost-plus with a fixed management fee means the family pays actual construction cost plus a flat builder fee that does not vary with project cost. The builder's compensation is fixed at engagement; cost overruns transfer to the family but the builder has no incentive to inflate scope. This model requires high mutual trust and benefits from open-book accounting.

Design Collaboration

Peters Custom Homes operates on a transparent fixed-price model with a documented contingency line item. Our base price reflects the actual cost of construction (trade subcontracts, materials, permits, insurance, project management) plus a stated builder margin. The contingency is shown on its own line and unused contingency is returned to the family at closeout. This is non-standard in the Charlotte market and exists because we believe pricing transparency is part of a luxury client experience.

Our typical builder margin runs 18-22% of project cost depending on project complexity, geographic distance, and scope. We disclose the margin during the contract conversation rather than at signature. Families who want a deeper open-book conversation can request line-item supplier and trade documentation; we provide it.

Change orders are priced at the same margin as the original contract, not at a higher 'gotcha' rate. Several Charlotte builders quietly mark up change orders at 30-50% on the assumption that families have low leverage mid-build. We do not, and we will put that policy in writing in the contract.

Construction & Craftsmanship

What we recommend families ask during builder interviews: (1) Which pricing model do you use, and why; (2) What is your builder fee or margin as a percentage of project cost; (3) Is your fee disclosed before contract signature; (4) How are change orders priced relative to the original contract; (5) How is unused contingency handled at closeout. The answers will quickly separate transparent firms from opaque ones.

Builders who refuse to disclose margin pre-contract are not necessarily dishonest, but they are operating in a tradition that families increasingly find unacceptable in the luxury tier. The trend across the industry is toward disclosure, and we are happy to be at the front of that trend.
