How to Manage Change Orders Without Getting Scammed (2026)
Change orders are where 70% of project disputes originate. These seven rules turn them from a scam vector into a normal project-management tool.
Step 1: Put every change in writing BEFORE the work is done — no exceptions
Verbal change orders are unenforceable in California small-claims court and routinely weaponized in disputes. Every change must be documented in writing, signed by both parties, BEFORE any work proceeds. The contract's change-order clause should require this. If it doesn't, amend it before signing.
Step 2: Require itemized cost breakdown: labor + materials + markup
A legitimate change order shows: labor hours × rate, material cost, equipment rental if any, markup (typically 10-20% of direct cost). A change order with just a lump-sum price is a red flag — ask for the breakdown. Cost transparency is the single most effective anti-scam measure.
Step 3: Document the schedule impact in days, not weeks
Every change order must state the schedule impact: 'Adds 3 business days to framing' or 'No schedule impact.' Vague 'minor delay' language is unenforceable. Specific day counts let you hold the GC to the aggregate completion date.
Step 4: Track cumulative change-order total against contract price
Maintain a running spreadsheet: original contract price, change orders 1..N by date and amount, cumulative total. When cumulative changes exceed 10% of contract price, pause and re-evaluate scope. When they exceed 20%, the project is usually heading for a major overrun and may need re-scoping.
Step 5: Reject change orders that could have been anticipated at the bid stage
Change orders for 'unforeseen' conditions are legitimate — asbestos discovered during demo, rotted subfloor behind cabinets, incorrect meter capacity. Change orders for items the GC should have anticipated (permits, inspection fees, standard materials) are hidden in the original bid's exclusions list and should be absorbed by the GC. Learn to distinguish.
Step 6: Maintain the right to get a competing quote for large change orders
If a change order exceeds $10K, reserve the right in the contract to get a competing quote from a different licensed contractor. This is rarely exercised but its existence keeps the GC's change-order pricing honest. Contract language: 'Change orders over $10K may be bid competitively at owner's discretion.'
Step 7: Use dispute resolution — written demand, then mediation, then arbitration or court
If a change order is contested: first, send a written demand letter citing the original contract. Second, offer mediation (California has free CSLB mediation for license-holders). Third, file in small-claims court (CA limit $10K for individuals) or binding arbitration if contract requires. CSLB's arbitration program handles disputes under $25K.

Who is Baily?
Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.
He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.
That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.
Baily was a businessman before he was a scientist. That’s our vibe too.
