What Happens When Plans Change Mid-Build
A change order is a formal modification to the original construction contract. It documents any change to the scope of work, materials, design, or timeline after the contract has been signed and work has begun. Change orders are a normal part of construction. But they need to be handled properly, or they can wreck your budget and your schedule.
Why Change Orders Happen
Some change orders are the homeowner's choice. You see the framing go up and realize you want a bigger window in the living room. Or you visit the tile showroom and decide to upgrade from the ceramic you originally picked to a porcelain that costs twice as much. Those are voluntary changes.
Other change orders are unavoidable. The building inspector requires additional structural reinforcement that was not in the original plan. The soil conditions are different from what the survey showed. A material you specified is discontinued and the replacement costs more. Those are things nobody could have predicted.
Either way, the process should be the same: document the change, agree on the cost and timeline impact, and sign off before the work happens.
How Change Order Pricing Works
A legitimate change order should include:
- A description of the change in clear, specific language
- The cost impact, broken down into materials, labor, and any subcontractor charges
- The timeline impact, meaning how many days or weeks the change adds to the project
- Both signatures from the homeowner and the contractor before work proceeds
Pricing for change orders typically includes the actual cost of materials and labor plus a markup, usually 15 to 25%, to cover the contractor's overhead and profit on the additional work. This markup is standard and should be stated in your original contract.
How Change Orders Affect Your Timeline
Every change order has a ripple effect. Adding a window means reframing part of the wall, which means the electrician needs to reroute wiring, which pushes back insulation and drywall. What sounds like a small change can add a week or more to your build timeline.
The bigger changes, like expanding a room or relocating plumbing, can add weeks. And if a change requires a permit revision, add the county's review time on top of that.
How to Minimize Change Orders
You can't eliminate them entirely. But you can keep them to a minimum:
- Make all design decisions during pre-construction. Pick your finishes, your fixtures, your layout, and your materials before the first shovel hits the dirt. The more decisions you make on paper, the fewer you make on the job site.
- Review your plans thoroughly. Walk through the floor plan, study the elevations, and make sure you understand every detail before you sign off on construction drawings.
- Budget for a contingency. Set aside 10 to 15% above your contract price to cover unexpected costs. This way, an unavoidable change order doesn't blow up your finances.
- Communicate with your contractor. If you are thinking about a change, bring it up as early as possible. A change discussed during framing costs a fraction of what it costs during the finish phase.
Your Rights as a Homeowner
In Florida, no work should be done on a change order until both parties have agreed in writing to the cost and scope. If a contractor does additional work without your written approval and then tries to bill you for it, you have legal ground to dispute that charge.
Keep copies of every change order, every email, and every text message related to changes on your project. Documentation protects you.
The Bottom Line
Change orders are part of construction. The goal is not to avoid them completely but to minimize them through good planning and handle them properly when they do come up. A good contractor will walk you through every change order honestly, explain the cost and timeline impact, and never proceed without your approval.
At J&N StructureWorks, every change order is documented, priced transparently, and signed by the client before any additional work begins. That is the right way to do it.
