Of all the frustrations HOA boards encounter during exterior construction projects, few generate more tension — or more heated conversations — than an unexpected change order landing on the table mid-project.
The project was bid at $180,000. The board approved it. The contract was signed. Work began. And now, six weeks in, the contractor is presenting a change order for $22,000 in additional work that wasn't in the original scope.
Is it legitimate? Is it avoidable? Should the board approve it, push back, or refuse it entirely?
The answers depend on what the change order is for, what the original contract said, and how well the board managed the scope and contracting process before work began. Understanding change orders — what they are, why they happen, and which ones are genuinely unavoidable versus which ones reflect a poorly written contract or a contractor with loose bidding practices — is one of the most practical things an HOA board can do to protect the association's budget and its relationship with its contractor.
What Is a Change Order?
A change order is a formal written amendment to a construction contract that modifies the original scope of work, adjusts the contract price, or changes the project schedule — or some combination of all three.
Change orders are a normal and legitimate part of construction. Construction projects — particularly exterior rehabilitation work on aging multifamily buildings — inevitably encounter conditions that could not be fully anticipated before work began. A change order is the formal mechanism for addressing those conditions: documenting what additional work is needed, what it will cost, and how both parties agree to handle it.
The problem is not that change orders exist. The problem is when they are used as a substitute for thorough upfront scoping, when they reflect conditions that a more thorough pre-construction assessment would have identified, or when they are presented in a way that gives the board little practical ability to push back — because work has already started and stopping would cause more disruption and cost than approving the change.
Why Change Orders Happen: The Legitimate and the Avoidable
Not all change orders are created equal. Understanding the difference between legitimate and avoidable change orders is the foundation of effective change order management.
Legitimate Change Orders: Genuinely Unforeseen Conditions
Some change orders reflect conditions that are genuinely impossible to fully anticipate before construction begins — and these are legitimate. The most common in exterior construction on California multifamily properties include:
Hidden structural damage. Waterproofing membrane replacement, balcony decking removal, stucco repair, and fascia replacement all involve opening up surfaces that conceal what's beneath them. A balcony deck that shows surface deterioration may reveal rotted framing, corroded connections, or compromised ledger boards once the deck surface is removed. A stucco repair area may reveal failed weather-resistant barrier or deteriorated sheathing that wasn't visible before the stucco was cut.
These conditions are genuinely concealed before construction begins and constitute legitimate change order territory — provided the original contract included clear language about how concealed conditions would be handled and how additional work would be priced.
Scope expansion at board direction. Sometimes the board itself initiates a change order — deciding mid-project to add a building to the scope, expand the caulking replacement to additional locations, or address a condition that was identified during construction but wasn't in the original scope. These board-initiated changes are straightforward and legitimate.
Code compliance requirements discovered during permitting. On projects that require permits, the permitting process occasionally identifies code compliance requirements that affect the scope — a drainage requirement, an accessibility upgrade, or a seismic compliance detail that wasn't part of the original design. These are legitimate change orders driven by regulatory requirements outside the contractor's or board's control.
Avoidable Change Orders: Scope and Contract Failures
Many change orders — perhaps the majority in HOA exterior construction — are not genuinely unforeseeable. They reflect failures in the pre-construction process that allowed conditions or scope items to remain undefined until they surfaced during construction. These are avoidable with the right preparation.
Inadequate pre-construction assessment. A contractor who bids a project based on a visual inspection from the ground, without getting close to surfaces or investigating conditions that show obvious signs of underlying damage, is setting up a change order situation. A thorough pre-construction condition assessment — including close-up inspection of balcony surfaces, fascia, window conditions, and stucco — identifies the conditions that will become change orders if not addressed upfront.
Vague scope of work language. A contract that says "repair stucco as needed" without defining the unit price for repairs, the method for measuring quantities, or the process for approving additional repair scope is a contract that will generate change orders. The ambiguity in the scope creates an opening for the contractor to expand the scope during construction in ways the board didn't anticipate — and a dispute about whether the expanded scope was reasonable.
Missing allowances for concealed conditions. A well-written contract for exterior rehabilitation work includes allowances for concealed conditions — unit prices for wood replacement, waterproofing repair, stucco repair, and other work that is likely to be needed but can't be fully quantified before surfaces are opened. When these allowances are missing from the contract, every concealed condition that is discovered becomes a separately negotiated change order — with the board in a weak position because the work has already started.
Scope items the contractor excluded without disclosure. A low bidder who wins the contract by excluding items that other contractors included — but doesn't make those exclusions explicit in the proposal — creates change orders for the excluded items when they inevitably need to be addressed. This is one of the most problematic change order scenarios because the board may not realize what was excluded until construction is underway.
The High-Pressure Change Order: Recognizing the Pattern
The most difficult change order situation boards face is one where the contractor presents a significant change order at a point in the project where approving it feels like the only practical option.
The pattern looks like this: work has begun, surfaces have been opened up, the community is partially disrupted — scaffolding is up, buildings have been pressure washed, residents are aware the project is underway. The contractor presents a change order for $15,000, $25,000, or more, citing conditions discovered during work. Refusing the change order or terminating the contract at this point would leave the project incomplete, require the board to find a new contractor mid-stream, and likely cost more than approving the change.
This dynamic — sometimes called "bid low, change order high" — is not unique to construction, but it is particularly effective in the HOA context where boards are volunteers managing a complex project alongside their regular lives and responsibilities.
The defense against this pattern is not to assume bad faith from every contractor. It is to structure the contract and the scope in a way that minimizes the conditions under which it can occur.
How to Protect Your HOA From Unexpected Change OrdersInvest in a Thorough Pre-Construction Assessment
The single most effective way to reduce unexpected change orders is to know as much as possible about the actual condition of the property before the contract is signed — not after work begins.
A professional condition assessment that gets close to surfaces, investigates areas showing signs of deterioration, and documents conditions with photographs gives both the board and the contractor a realistic picture of what the project involves. Conditions that are identified in the assessment can be addressed in the scope — either by including them directly or by establishing allowances for the likely quantities of additional work.
A condition assessment is not free — but it is almost always less expensive than the change orders it prevents.
Require Detailed Scope of Work with Explicit Exclusions
As we've covered in previous posts, a detailed written scope of work is your primary protection against scope disputes. For change order prevention specifically, the scope should include:
Unit prices for concealed condition work. For work that is likely to be needed but can't be fully quantified upfront — wood replacement, waterproofing repair, stucco repair beyond the areas identified in the assessment — require contractors to include unit prices in their proposals. Unit prices agreed to before construction begins are far less contentious than prices negotiated after conditions are discovered.
Explicit exclusion lists. Require every bidding contractor to list what is not included in their proposed price. A contractor who explicitly excludes stucco repair beyond a specified quantity, or who excludes structural repairs if balcony framing is found to be damaged, has disclosed that exclusion before the contract was signed. The board can evaluate whether the exclusion is acceptable or whether the scope needs to be revised.
Allowances for concealed conditions. Include a defined allowance — a dollar amount or a unit quantity — for concealed condition work that is likely based on the condition assessment. When the allowance is exceeded, a formal change order process is triggered. When it is not fully used, the unused portion reduces the final contract price.
Establish a Clear Change Order Process in the Contract
The contract should define exactly how change orders will be handled — before they arise. Key provisions include:
Written authorization required. No additional work should proceed without written board authorization. A contractor who performs work beyond the contract scope without written approval and then presents a change order for it is in a legally weak position — and the board should know this going into the project.
Pricing method defined upfront. The contract should specify how change order work will be priced — at agreed unit prices, at time and materials with a specified markup, or at negotiated lump sum. Leaving the pricing method undefined creates disputes when change orders arise.
Board contact for change order authorization. Designate a specific board member — or the property manager — as the authorized contact for change order approvals. This prevents situations where a contractor gets verbal approval from a well-meaning board member who didn't have authority to commit the association to additional expenditure.
Threshold for board versus management approval. For HOA communities managed by a professional management company, the contract should specify which change orders can be approved by the property manager and which require full board authorization. Many associations set a threshold — changes under a certain dollar amount can be approved by the manager, larger changes require board action.
Review Change Orders Carefully Before Approving
When a change order is presented, the board's response should be deliberate — not reflexive approval or reflexive refusal.
Verify the condition. Before approving a change order for concealed damage, have the contractor show you the condition. Photographs, a site visit by a board member or the property manager, or a review by an independent consultant gives the board a factual basis for evaluating whether the additional work is genuinely necessary and whether the proposed cost is reasonable.
Check the unit prices. If the contract included unit prices for concealed condition work, confirm that the change order is priced at those agreed rates — not at a different rate the contractor is now proposing.
Assess whether the condition was foreseeable. If the additional work relates to a condition that a more thorough pre-construction assessment would likely have identified, that is worth noting — both for the current change order negotiation and for future contractor selection decisions.
Get a second opinion on significant changes. For change orders exceeding a material dollar threshold — many boards set this at $5,000 to $10,000 — consider having the proposed additional scope and pricing reviewed by an independent contractor or construction consultant before approving. The cost of a second opinion is often less than the savings from negotiating a more reasonable change order price.
Document Everything
Every change order — approved or rejected — should be documented in writing. Approved change orders should be signed by both parties before additional work proceeds. Rejected change orders should be confirmed in writing with a brief explanation of the board's reasoning.
This documentation protects the board in the event of a dispute after the project is complete — about what was authorized, what was paid for, and what remains the contractor's responsibility under the original contract.
What Legitimate Change Order Management Looks Like
A contractor with well-developed change order practices will:
- Present change orders in writing with a clear description of the condition requiring additional work, the proposed scope of the additional work, the proposed price, and the impact on the project schedule
- Photograph the condition before proceeding with additional work, so the board can verify what was found
- Price additional work at the unit rates agreed to in the original contract wherever applicable
- Seek written authorization before proceeding — not after
- Provide a running change order log so the board always knows the current approved contract value versus the original contract price
A contractor who presents verbal change orders, proceeds without authorization, prices additional work at rates higher than the agreed contract unit prices, or resists documentation of change orders is a contractor whose change order practices warrant scrutiny.
The Whitestone Approach to Change Orders
At Whitestone Industries, we build our proposals to minimize the conditions that generate unexpected change orders. We conduct thorough pre-construction assessments, include unit prices for concealed condition work in our contracts, list our exclusions explicitly, and establish clear change order processes with every client before work begins.
When conditions arise during construction that require a change order, we document the condition with photographs, present the change order in writing before proceeding, and price the additional work at the rates agreed to in the original contract. We don't present change orders as surprises — we present them as documented findings with a proposed solution and a transparent price.
We believe that a board that fully understands the change order process going into a project is a board that can manage the project confidently from start to finish — and that the trust built through a transparent, well-documented project is the foundation of a long-term contractor relationship.
If your community is preparing for a major exterior project and you want to understand how to structure the contract and scope to minimize change order exposure, we'd welcome the conversation.
