Change Orders: How They Work, What They Cost, and How to Keep Them Rare
A change order is any signed modification to the contracted scope — and on a well-run remodel, every single one is documented and priced before the work happens, never after. The myth is that change orders are how contractors pad the bill. On honest projects they're how *you* stay in control: the paper trail that turns "while we're at it" and "we found something" into decisions you made with numbers in front of you. Here's the whole mechanism, from 20+ years running changes across 130+ LA projects.
The three species of change order
1. Owner-requested changes. You decide mid-build to move a wall, upgrade the slab, add the pot filler. Entirely legitimate — it's your house — and entirely optional. These price at real cost plus schedule impact, and the discipline is making the decision with both numbers visible.
2. Discovered conditions. The wall opens and there's knob-and-tube wiring, galvanized plumbing, subfloor rot, or a previous owner's non-code framing. Not optional — code and safety require addressing what's found. This is exactly why our quotes on older LA stock carry a discovered-conditions reserve: the money is pre-approved, so the discovery becomes a documented draw against the reserve instead of a mid-project ambush.
3. Jurisdiction-driven changes. LADBS plan-check corrections, an inspector's field interpretation, HPOZ board conditions on your window spec. Rarer, but real in LA's overlay zones — and they're nobody's fault, which is exactly why the process for pricing them fairly has to exist before they happen.
Knowing which species you're looking at tells you how to respond: type 1 is a choice, type 2 is a reserve draw, type 3 is a compliance cost. A builder who blurs the three categories is negotiating, not documenting.
The paper trail that protects both sides
Our process — and what you should demand from anyone:
Written description of the change: what's being added, removed, or modified, specific enough to point at.
Price, itemized — labor, materials, and any subcontractor cost, in the same line-item format as the original quote so you can sanity-check it against the numbers you already vetted.
Schedule impact, stated in days or weeks — even when it's zero, it's stated. Per our timeline guide: every change adds days-to-weeks, and seeing that cost up front changes half of the "small" requests.
Your signature before work proceeds. This is the line that matters. Work that starts before pricing is agreed converts your leverage into their leverage — you're approving retroactively under schedule pressure.
A running change-order log — numbered, dated, with a live revised contract total. On a months-long project, memory is not a system; the log means the final invoice can't contain surprises because you watched the total move in real time.
California's contractor law backs this up: home-improvement contract changes are supposed to be written and signed. Verbal change agreements are unenforceable ambiguity that hurts whichever side remembers differently.
Why change-order pricing looks higher than bid pricing
A fair question clients ask: "why does adding this now cost more than if it had been in the original bid?" Three honest reasons — and one dishonest one to watch for:
Sequencing loss. Work added mid-stream interrupts planned trade sequencing. The electrician who was done comes back for a second mobilization; the drywall patch happens after paint instead of before. Out-of-sequence work genuinely costs more than the same work planned.
Small-quantity pricing. The original tile order shipped at quantity; the change adds a partial box at single-unit pricing plus delivery.
Compressed decisions. Mid-build changes often need expedited materials — the 15% rush premium our timeline guide mentions for cabinet expedites applies broadly.
The dishonest version: lowball bidders who priced the original scope at a loss and make margin on captive-audience change orders. The tell is a pattern — every discovered condition priced like a hostage negotiation. Protection: the discovered-conditions reserve up front, itemized change pricing you can compare to original line items, and honestly, choosing the transparent bid in the first place (our pricing-transparency guide covers the bid-comparison method).
How to keep change orders rare (the real goal)
The best change order is the one that never exists because the decision happened during design:
Lock design before permit, resist relitigating after. Per our timeline guide, every revision after cabinets are ordered costs 2–6 weeks. The design phase is cheap to change; construction is expensive to change. Spend the extra week deciding.
Walk the design in the space. Blue tape on the floor where the island lands, painter's-tape outlines at outlet heights. A remarkable share of mid-build changes are things that were visible on paper but only felt real in person — feel them before demo.
Pre-decide the discoverables. On pre-1960s LA stock, we scope the site visit assuming galvanized supply and dated wiring behind the walls we'll open, and price the likely-case into the base quote or the reserve. Fewer surprises left to discover.
Batch your wishes. If mid-build inspiration strikes, collect it — we review the batch at the next scheduled decision point and price it together, instead of bleeding sequencing on serial one-offs.
Accept the freebie boundary. Moving one outlet before drywall: often genuinely free, and we say so. The instinct to extrapolate ("that was free, so this should be too") is where goodwill goes to die. Free is free when it's actually free; the log keeps everyone honest either way.
Frequently asked questions
- Am I obligated to accept a change order?
- Owner-requested ones — obviously optional. Discovered-condition changes are only "optional" in the sense that code compliance isn't: exposed knob-and-tube must be addressed once found. What you're never obligated to accept is unpriced work — everything can wait for the written number, and legitimate builders never start change work before signature.
- What's a normal amount of change orders on a remodel?
- On projects with real design phases and discovered-conditions reserves: a handful, mostly small, largely reserve draws on older homes. A project generating change orders weekly signals a rushed design phase or a lowball original bid. The total matters less than the pattern — documented, priced-before-work changes are health; retroactive pricing is disease.
- How fast do change orders get priced?
- Simple ones (fixture swap, added outlet circuit): a day or two. Ones needing subcontractor quotes or structural input: up to a week. The discipline cuts both ways — we won't rush a number to keep schedule pressure on your signature, and the affected work pauses rather than proceeding unpriced.
- Do change orders change my payment schedule?
- They adjust the contract total, and payments continue tracking completed work — California's progress-payment principle doesn't change (see our payment-terms guide). What to refuse: large upfront payment demands attached to change orders. The change order prices the work; payment follows performance, same as the base contract.
- What happens if we disagree about whether something is a change or was included?
- The original scope document settles it — which is the real argument for line-item quotes over lump sums (our pricing-transparency guide). Where scope language is genuinely ambiguous, we've found the honest resolution is splitting the difference and tightening the language going forward. Chronic scope disputes are a contractor-selection symptom, not a construction inevitability.
