Before You Sign: What to Check in a Custom Home Contract
When you're building a custom home, there's a great deal to review before construction begins.
Plans, specifications, finishes, budgets, and timelines all need to come together before work gets underway.
One document ties many of those decisions together: the construction contract.
Before signing, it's worth looking beyond the overall price and taking a closer look at what the agreement actually says.
Who is responsible for what? What exactly is included? How are payments handled? What happens if the schedule changes or something unexpected affects the project?
A well-structured contract gives both the homeowner and builder a clear reference point for the work ahead. Taking the time to understand those details before signing can help establish clearer expectations from the start.
What Should I Look for in a Custom Home Construction Contract?
At the heart of a construction contract are four basic questions:
● Who are the parties involved?
● What exactly are they building?
● How much will it cost?
● When will it be completed?
These questions provide the foundation for the agreement.
The contract should clearly identify the parties, describe the project, establish how the cost will be determined, and set expectations for when construction will begin and when it is expected to be completed.
Everything else in the agreement should help clarify those basic expectations.
If an important part of the project is difficult to understand or doesn't have a clear answer, it's worth addressing before signing.
How Do I Compare Fixed-Price and Cost-Plus Contracts?
One of the most important things for a homeowner to understand is how the construction price is structured.
A fixed-price contract generally establishes an agreed construction price for a defined scope of work, subject to the terms, allowances, exclusions, and changes described in the agreement.
A cost-plus contract generally involves paying the builder for the project's actual costs, plus an agreed fee or markup. The final cost can therefore change as actual project costs are incurred.
Neither structure can be evaluated properly by looking at the contract label alone.
Before signing, understand:
● What is included in the construction price
● What is excluded
● How allowances are handled
● What builder fee or markup applies
● How changes are priced
● How unexpected costs are handled
● How the construction budget is tracked
● What costs can change during construction
● What documentation the homeowner receives
The important question is not simply whether a contract is fixed-price or cost-plus. It is how clearly the agreement defines the scope, costs, responsibilities, and process for changes.
Homeowners should also have their own legal counsel review the contract before signing.
Does the Contract Match the Latest Plans and Specifications?
The contract should reflect the home you have actually agreed to build.
Before signing, check that the agreement references the most current construction drawings, written specifications, and detailed scope of work.
These documents establish what is included in the project, including materials, finishes, and the quality standards expected for the work.
This is particularly important in a custom home, where plans and selections can evolve throughout the design process.
The contract should be based on the current information rather than an earlier version of the project.
If something in the agreement is inconsistent with the current plans or specifications, address it before signing.
What Should Be Included in the Scope of Work?
A clear scope of work helps both the homeowner and builder understand exactly what is included in the project.
Before signing, review:
● Construction drawings
● Written specifications
● Materials and finishes
● Allowances
● Site work
● Permitting responsibilities
● Contractor responsibilities
● Project management
● Construction supervision
● Items specifically excluded from the contract
The more clearly the scope is defined, the easier it is to understand the contract price and identify changes later.
This is particularly important when comparing proposals from different builders. Two proposals may have different prices because their scopes, allowances, specifications, or exclusions are different.

How Are Payments Handled in a Custom Home Contract?
The contract should make the payment structure clear before construction begins.
Many custom home projects use draw requests, which are payment requests submitted as construction progresses. Depending on the project, payments may be based on specific milestones or made monthly.
One important detail to understand is what triggers a payment.
Homeowners should understand:
● What work must be completed before a payment is requested
● How each draw is documented
● Who reviews the draw
● How long the homeowner has to process payment
● Whether payments are tied to specific construction milestones
● How payments relate to the overall construction budget
Understanding the payment process ahead of time can make it easier to track both construction progress and project spending.
How Does the Contract Handle Delays?
Cost is only one part of the agreement. The contract should also establish expectations around time.
Review the stated start and completion dates and look closely at how the agreement handles delays.
Construction delays can have different causes, including:
● Late homeowner decisions
● Contractor scheduling issues
● Weather
● Supply chain issues
● Permitting
● Changes to the project
● Other circumstances outside the original schedule
The contract should explain what happens in these situations and whether additional time or cost applies.
Not every delay carries the same responsibility. A homeowner decision that comes in late is different from a scheduling problem, which is different again from a hurricane or permitting delay.
The more clearly these situations are addressed in the contract, the easier it is to understand what happens when the original timeline changes.
What Happens When Something Unexpected Changes?
Some of the most useful parts of a construction contract address circumstances that may never happen.
A custom home project can be affected by permitting delays, changes to building codes, labor shortages, or major weather events such as hurricanes.
These situations can introduce additional time, costs, or decisions that were not part of the original plan.
Before signing, look at how the contract addresses these possibilities.
Ask:
● What happens if permitting takes longer than expected?
● What happens if building requirements change?
● How are code changes handled?
● What happens if labor shortages affect the schedule?
● How are unexpected costs addressed?
● How are additional days added to the schedule?
● Who is responsible for making and approving changes?
Having the process established in advance can reduce uncertainty if circumstances change during construction.
How Are Change Orders Handled?
Changes are common during a custom home project, so homeowners should understand the change-order process before construction begins.
The contract should explain how changes are:
● Requested
● Documented
● Priced
● Approved
● Added to the scope
● Reflected in the budget
● Reflected in the schedule
A change should not simply become an unexpected cost at the end of the project.
Homeowners should understand how the builder communicates the cost and schedule impact of a proposed change before approving it.
Who Carries the Risk When the Project Changes?
Some contract provisions determine how financial responsibility is handled when a project does not proceed exactly as planned.
Liquidated damages are one example. These provisions can establish an agreed amount associated with certain delays, but their application can depend on the specific circumstances and contract language.
Another approach is fixed General Conditions.
At Landmark Custom Homes, certain General Conditions costs, such as trash removal, site utilities, and project manager and superintendent salaries, may be fixed upfront. If the project takes longer than expected, Landmark absorbs those additional costs rather than passing them on to the homeowner.
For homeowners, the takeaway is simple: don't just review the total contract price. Understand how the agreement handles costs and responsibility when circumstances change.
What Are Common Red Flags in a Custom Home Contract?
Some contract language deserves a closer look before you sign.
Common issues to question include:
● A vague scope of work that leaves important parts of the project unclear
● Change-order language that does not explain how changes are documented or priced
● An undefined completion timeline
● Fees that are not clearly identified
● Allowances that are not explained
● Exclusions that are difficult to understand
● Responsibilities that are not clearly assigned
If something important is unclear in writing, ask questions before construction begins rather than trying to resolve the issue later.
How Should I Verify the Builder Before Signing?
The contract is only one part of evaluating a builder.
Before signing, homeowners should also review the builder's:
● Relevant experience
● Completed projects
● Client references
● Construction team
● Supervision structure
● Communication process
● Proposal and scope
● Licensing and insurance information
In Florida, homeowners should verify the builder's licensing and understand who is legally responsible for the construction work.
Because contract and licensing requirements can have legal implications, homeowners should consult their own attorney and appropriate state or local authorities when reviewing these matters.
What Questions Should I Ask Before Signing a Custom Home Contract?
Before signing, you should be able to answer questions such as:
● What exactly is included in the contract?
● What is excluded?
● Which plans and specifications control the agreement?
● How is the construction price determined?
● Is the contract fixed-price, cost-plus, or another structure?
● How are allowances calculated and handled?
● How are payments and draws handled?
● How are change orders documented and approved?
● What happens if the project is delayed?
● What happens if permitting or code requirements change?
● Who is responsible for additional costs?
● Who supervises the construction?
● How is the budget tracked?
● What happens if the scope changes?
● What warranty responsibilities are included?
If you still have questions about the scope, payment structure, timeline, responsibilities, or what happens when unexpected circumstances arise, raise them before signing.
A contract does not eliminate every uncertainty in custom home building. It establishes how the homeowner and builder agree to handle the project when those uncertainties arise.
A Construction Contract Should Create Clarity
A well-structured construction contract helps establish clear expectations around scope, costs, payments, timelines, responsibilities, and changes before construction begins.
The goal is not simply to have a document that everyone signs.
The goal is to have a clear agreement that both the homeowner and builder understand before work begins.
At Landmark Custom Homes, we believe those details are an important part of keeping a custom home project organized and reducing misunderstandings along the way.
For homeowners planning a luxury custom home in South Florida, understanding the agreement before you sign is one more way to begin the project with clarity.
Important: A construction contract is a legal document. Homeowners should consult their own legal counsel before signing.
