Change Orders Explained: Costs, Causes & How to Avoid Them

Few phrases make renovating homeowners tense up like "we'll need a change order." Yet change orders are neither scams nor failures — they are the formal mechanism by which a construction contract adapts to new information or new decisions. Understanding how change orders work, what they genuinely cost, and how to minimize them is one of the most valuable pieces of budgeting knowledge a Florida homeowner can have.

What a Change Order Is

A change order is a written amendment to your construction contract that documents a change in scope, price, or schedule — signed by both parties before the changed work proceeds. A proper one specifies:

1. Exactly what work is being added, removed, or altered
2. The cost impact, itemized
3. The schedule impact, in days
4. Signatures from both homeowner and contractor

If a contractor performs changed work on a handshake, both sides are exposed. Insist on paper — a professional licensed general contractor will insist right along with you.

The Three Causes of Change Orders

1. Homeowner-driven changes

The most common cause. You see the space opened up and want the doorway widened; you fall for a different tile mid-project. These are legitimate choices — they simply carry costs, and often schedule impacts, that deserve clear documentation.

2. Unforeseen conditions

Demolition reveals what estimates could not: rotted framing, corroded cast-iron drains under the slab, unpermitted past work that must be corrected under the Florida Building Code. In South Florida's older housing stock, humidity and termites make hidden damage a routine discovery. This is what your contingency budget exists for.

3. Design gaps

When drawings and specifications are incomplete or contradictory, someone must fill the gap — and that becomes a change order. This cause is the most avoidable, and it is where contractor selection matters most.

What Change Orders Really Cost

Changed work is priced less favorably than contracted work, for structural reasons: it interrupts sequencing, may require remobilizing trades, can trigger new permits or inspections, and often involves rush materials. Typical Florida experience:

A well-run project might see change orders total 5–10% of contract value. Poorly planned projects can see 25% or more.

How to Minimize Change Orders

• Finalize selections before construction starts. Every tile, fixture, and finish chosen up front is a change order that can never happen.
• Invest in complete design documents. Vague drawings are invitations to disputes.
• Walk the design in detail — many firms can model spaces so you experience the layout before it is framed.
• Carry a contingency for true unknowns, especially in older homes.
• Choose a design-build firm where architect and builder are the same team. When design, engineering, and construction live under one roof, design-gap change orders largely disappear.

Projects with well-defined scope — whether a kitchen remodel or a full home renovation — consistently finish closer to their original number.

Reading a Change Order Before You Sign

Treat every change order like the small contract it is. Confirm the description matches what you discussed, the price is itemized rather than a lump sum, and the schedule impact is stated in days — silence on schedule is how "one small change" quietly adds three weeks. Ask how the change interacts with permits: some alterations require revised drawings or new inspections, and that cost belongs in the document, not in a later surprise. Five minutes of careful reading protects both your budget and the relationship.

When a Change Order Is Good News

Not every change order is a problem. Sometimes opening a wall reveals the opportunity to fix an issue properly — replace a corroding pipe while it is exposed, add blocking for future grab bars, upgrade insulation. Paying once, while access is open, is far cheaper than paying twice later. The measure of a good contractor is not zero change orders; it is honest, documented, fairly priced ones.
