Managing Change Orders on Your Houston Custom Home

What Is a Change Order

A change order is a written modification to the original construction contract that adds, removes, or alters work scope, adjusts the contract price, or changes the project schedule. Every change order should be in writing and signed by both the owner and the builder before work proceeds.

Change orders are not inherently bad. They are the correct mechanism for handling legitimate changes and unforeseen conditions. The problem arises when they are numerous, undocumented, or driven by incomplete design rather than genuine owner decisions.

The Three Sources of Change Orders

Nearly all change orders on Houston custom homes fall into three categories:

• Owner-initiated scope changes: adding square footage, changing the floor plan after framing, upgrading to a material not in the original selections, adding structural features like cantilevered stairs or a roof terrace.
• Unforeseen field conditions: buried utilities, rock encountered during excavation, poor soil conditions not captured in the geotech report, hidden deterioration in adjacent structures during additions.
• Incomplete drawings: when construction starts before engineering or details are finished, field decisions fill the gap. Each field decision is effectively an undocumented change order that eventually gets priced.

How Change Orders Are Priced in Houston

Reputable Houston builders price change orders at actual cost plus a markup for overhead and profit, typically 15–25%. The markup is disclosed in the contract. Some builders cap change order markup; some do not. Read the change order clause before you sign the original contract.

Change orders for structural modifications are the most expensive because they involve engineering fees, possible permit revisions, and labor to undo and redo completed work. A floor plan change after framing that looks small can trigger $30,000–$80,000 in change order costs when engineering revision, framing demo and rebuild, and permit amendment are included.

Change orders for finish upgrades are more predictable: the price difference between the allowance item and the selected item, plus the builder markup. If a tile allowance was $12 per square foot installed and you select a $28 per square foot tile, the change order is roughly $16 × square footage × 1.20.

How to Minimize Change Orders

The most effective strategy is completing all design decisions before breaking ground. This means signed architectural drawings, structural engineering complete, MEP coordination done, and every finish selection made with a specific product, model, and color — not an allowance — before the permit is submitted.

Second, build a realistic contingency budget (8–12% of construction) specifically for change orders, and treat it as real money. Owners who budget for change orders make calmer decisions when they occur.

Third, resist the temptation to make design changes during construction. Walk the framing carefully before drywall and confirm every dimension, window location, door swing, and outlet placement. Changes caught at framing cost far less than changes discovered after drywall.
