UNDERSTANDING ESTIMATES & CONTRACT TYPES
Updated: Apr 6
For many homeowners, reviewing a construction estimate can feel overwhelming. Numbers, line items, and unfamiliar terminology often make it difficult to know what is truly included, and what isn’t.
A well-prepared estimate should do more than outline costs. It should provide clarity, set expectations, and establish trust from the outset. Understanding a few key components, such as allowances, exclusions, and contingencies, can make the difference between a smooth project and one filled with surprises.
Allowances: Planning for the Unknown
Allowances are placeholders for items that have not yet been fully selected at the time the estimate is prepared. These are typically finish items such as flooring, cabinetry, appliances, lighting, etc.
Rather than delaying the project until every decision is finalized, allowances provide a way to move forward while maintaining flexibility.
However, not all allowances are created equal. A low allowance may make an estimate appear more competitive, but can lead to increased costs later when final selections are made.
A well-structured estimate uses realistic allowances aligned with your expectations, helping ensure that the budget reflects the level of finish you intend to achieve.
Allowances are typically included in the estimate as a defined budget for specific items or finishes. Once selections are finalized, the actual cost is reconciled against that allowance. If the selected items come in below the allowance, the difference is credited back to the owner. If selections exceed the allowance, the additional cost is processed through a formal change order. This approach maintains flexibility during the early stages while ensuring the project budget remains accurate and transparent as decisions are made.
Exclusions: What is Not Included
Exclusions are just as important as what is included. These outline the scope items that are intentionally left out of the estimate.
Common exclusions may include:
Items that the owner has requested to purchase or complete on their own
Landscaping (if only the actual home structure is being priced)
Unforeseen site conditions
Winter conditions, or costs dealing with snow removal, heating and tenting of the structure, etc. It's hard to predict what a winter will look like and some contractors and owners prefer to handle this on an as-needed basis.
Clear exclusions protect both the homeowner and the builder by defining boundaries upfront. Without them, assumptions can lead to misalignment, delays, and unexpected costs.
A transparent builder will always make exclusions visible and easy to understand, not hidden in fine print.
Contingencies: Preparing for the Unexpected
Even with careful planning, construction projects can encounter unforeseen conditions—especially in remodels or complex builds.
Contingencies are funds set aside to address these unknowns without disrupting the entire project. This might include:
Hidden structural issues
Material price fluctuations (yearly price increases from suppliers, tariffs, etc.)
Design adjustments during construction
Rather than being seen as an added cost, contingencies should be viewed as a tool for maintaining momentum and control when the unexpected arises.
Hard Bid vs. Cost-Plus: Understanding the Contract Structure
The structure of a contract plays a significant role in how a project is managed and how costs are controlled.
A Hard-Bid (or Fixed Price) provides a defined cost based on a clearly established scope. This approach offers predictability, as the total investment is determined upfront. To account for unknowns, builders often carry a degree of built-in protection within the estimate, ensuring the project can move forward without disruption if conditions vary.
A Cost-Plus approach is based on actual project costs, fully shared with the owner, plus a clearly defined management fee (overhead and profit, or OH&P). Fees may vary depending on project scope, size, and complexity, but should always be transparent and outlined in the contract. This model provides greater flexibility and transparency, particularly when selections and details are still evolving. With a trusted and aligned builder, it also enables more efficient allocation of resources, ensuring funds are directed where they create the most value.
Both approaches are valid and widely used across the industry. Builders typically operate within a model that aligns with their process and the type of projects they deliver. The right choice depends on the level of clarity in the project, your preference for flexibility versus predictability, and the level of trust and alignment with your builder.
