20 Common Budget-Busting Construction Change Orders That Occur During Additions, Remodels, and New Construction

The New Avenue online project management system is reviewing hundreds of projects at any given time. We track all of the change orders submitted by contractors in these projects.

This post highlights the 20 most common change orders. These are changes that may be called "surprises" on your project. Often, they shouldn't be surprises at all. You should be planning on these changes.

You can review this checklist and check if your project budget includes them. Do this, and you can be prepared to review any bid. You can make sure the full scope of work is included in the price you are quoted.

First, a note on what a change order is.

"Change Order" is a term used in the construction industry, and it's something that many owners are completely unaware of. One of the unfortunate facts of many remodels, ADUs, and Custom Homes is blown budgets. One cause of this is that unscrupulous contractors use change orders in a strategic and deceitful way to offer low bids. They then make your project a miserable experience as they introduce additional hidden costs. Some (but certainly not all) contractors make all of their profit off of these change orders. This is true for projects ranging from small $10,000 projects to billion-dollar bridges. 

The good news is that many contractors have noble motivations. They became contractors because they want to build beautiful homes, and they want you to be happy. Even a perfect project can have 20+ change orders that you willingly choose to make. In fact, you can have 20 or more change orders and still complete the work on budget. Use this list to improve your next remodeling experience.

Here is the list of top 20 change orders. This list is from all of the projects reviewed, not just one. The average of 8% increase from the original construction bid to the final completed project cost is split evenly between discretionary and non-discretionary changes.

Discretionary Change Orders

In our review, 13 of the 20 most expensive change orders were "discretionary."  Discretionary change orders are changes the customer asked for that were not part of the original bid. It is an add that the customer requested after construction started. They often pop up as a project is progressing on budget. If the customer has a little reserve money socked away, they may decide to add something nice or upgrade to more expensive materials for example. We always recommend you talk to your design team before making changes to the design. It is easier and cheaper to make the changes on paper before making changes in the field.

1) Add a new window to the home. Since windows were being added in the addition, it made sense to add a bay window to the existing living room at the same time. Amount: $5,684

2) Upgrade window quality to Marvin windows and Velux skylights. Amount: $4,086

3) Landscaping:  Install a screened-in trash area and stone flatwork in the yard. Amount: $3,393

4) Add a gas line to a backyard cottage to upgrade from electric stove to gas:  $3,000 (Note, California is phasing out the use of gas in new residential projects. And for sustainability reasons, we recommend going all electric, with induction cooktops and solar panels whenever possible.)

5) Change siding from Hardi board to natural cedar siding. Amount: $2,325

6) Add tile to main home entry stoop. Amount: $1,880

7) Add crown molding to living room and kitchen. Amount: $1,761

8) Add a skylight in an ADU loft. Amount: $1,487

9) Additional tile wainscoting in bathroom and tile nook in shower. Amount: $1,050

10) Change from stained concrete floor to tile floor throughout 610-square-foot space. Amount: $1,050

11) Add false wood beams to living room. Amount: $996

12) Addition of extra lighting fixtures throughout house. Amount: $835

13) Provide and install 8'x4' fence and lattice made of redwood for trash cans. Amount: $771

Non-Discretionary Change Orders

These change orders (numbers 14 through 20) were "non-discretionary." These are the unpleasant changes. These changes are difficult to manage because sometimes the cause is beyond the owner's or builder's control. A building inspector may exercise their authority and request something that is not in the plan or the budget. Other times, a designer, engineer, or contractor overlooked something. Again, in a complex project this is common and a little leeway is fair. But if this happens too often, it becomes a real question of competence.

14)  Foundation improvement: Excavate an additional two feet for foundation improvements and fill with compacted gravel and additional concrete. Amount: $6,042

15) Fire proofing of laundry room. Amount: $2,151

16) New water line from the street to the main home in order to increase capacity for fire sprinklers. Amount: $5,505

17) Add fire sprinklers due to new building code requirements. Amount: $4,360

18) Replace electrical panel in main home with a new 200-amp service, including a wire from the street, new panel, and all breakers. Amount: $3,272

19) Soils report required for foundation work: Amount: $4,000 for the engineer and $10,000 or more for the foundation work.

20) Survey after the foundation forms are set: Some owners try to avoid getting a survey for $3,000–$5,000 to save money. This is not recommended. We always request a suervey be performed before construction begins. If there is no survey and the inspector shows up and requests a letter from a surveyor, you will just pay the surveyor later for the same work. If the foundation is off by a few inches (or your home is not where you thought it was, which happens a lot), then you'll have to pay to move the foundation forms which can add thousands of dollars. Amount: $1,000 and up in unnecessary costs.

 

A well-run project should stay within 10% of the bid, and we start each project with the goal of having zero change orders.
