How to read a new home construction proposal: allowances, exclusions and change orders

Learn how to read and compare a new home construction proposal: what allowances really cover, which exclusions to question and how change orders should work.

A new home construction proposal is more than a total at the bottom of the page. Two proposals for the same drawings can differ by a wide margin simply because they include different work, assume different finishes or leave different items out. This guide shows how to read the scope, allowances, exclusions and change-order terms so you compare like with like.

Read the proposal next to your drawings and your selection list. Every question you ask now is cheaper than a surprise during construction.

Confirm what the proposal is based on

The first page to check is not the price. It is the list of documents the proposal was priced from. Look for the drawing set name and date, the structural drawings, the soils report and any specifications or selection sheets.

If two contractors priced different revisions of your plans, their numbers are not comparable. Ask each one to confirm the same set, or to list the differences they assumed.

Also check the proposal type. A budget estimate built on concept drawings is useful for planning but will carry many assumptions. A detailed proposal on permit-ready drawings should have far fewer.

Read the scope trade by trade

A clear proposal breaks the work into parts you can recognize: site work and demolition, grading, foundation, framing, roofing, windows and doors, exterior finishes, plumbing, electrical, HVAC, insulation, drywall, cabinets, flooring, tile, painting and final cleanup.

Be wary of single-line items such as "complete construction per plans." They make it hard to see what was actually priced. Ask how the following are handled, because they are often where proposals differ:

Utility connections and any fees paid to utility providers
Permit fees, plan check fees and inspections
Soils-related work such as over-excavation or special foundation elements
Temporary facilities: fencing, toilets, power, water and dumpsters
Landscaping, hardscape, driveways and fences
Appliances, window coverings and low-voltage systems
Final cleaning and protection of finished work

Understand allowances before you rely on them

An allowance is a placeholder amount for something not yet selected, such as tile, plumbing fixtures, lighting or cabinets. It lets the project be priced before every decision is made.

The risk is that allowances look like savings on paper. If a proposal carries a low tile allowance and you select a more expensive tile, the difference becomes an added cost later. When comparing proposals, line up the allowances side by side and ask whether each one realistically matches the level of finish you want.

For each allowance, ask three questions. Does the amount cover material only, or material and installation? Does it include tax and delivery? What happens to unused money if you choose something less expensive?

Name the finish, not just the quality level

Descriptions such as "premium flooring" or "custom cabinetry" can mean very different things to different people. Where you have already chosen products, list them in the proposal by product type, size, finish and quantity.

Where a selection is not ready, the proposal should say it is an allowance and give the amount. A mix of named products and clear allowances is normal. Vague quality words with no amount behind them are not.

Question the exclusions list

Exclusions tell you what the contractor did not price. They are not a warning sign on their own; every honest proposal has them. The concern is an exclusion you did not expect.

Read the list slowly and mark anything that your project clearly needs. Common exclusions include utility company charges, special inspections, soils testing, engineering revisions, rock excavation, hazardous material removal, landscaping and appliances. If an excluded item is necessary, ask who will provide it and add it to your budget.

When comparing two proposals, move each exclusion from one onto the other as a cost you will carry. That is often what makes a lower total less attractive.

Know how change orders will work

Changes happen on almost every custom home, whether from your own decisions, hidden conditions or plan check comments. What matters is that the process is written down before work begins.

Look for a change-order clause that says changes are documented in writing, priced before the work is done and signed by you before they proceed. Ask how pricing is calculated for added work and how schedule impacts are shown. Also ask whether pricing for changes includes overhead and markup, so there are no surprises later.

A simple rule protects everyone: no verbal changes. If a change is not on a signed change order, it is not approved.

Check the payment schedule and assumptions about time

The payment schedule should follow progress on site. Payments tied to completed stages, such as foundation, framing, rough-in inspections and drywall, are easier to track than payments tied to dates alone. Check the deposit terms and what is due at completion.

Also read what the proposal assumes about time. Does it state a working schedule or a duration estimate, and what could change it? Weather, plan check comments, utility work and late selections can all move dates. A proposal that explains its assumptions is more useful than one that simply names a finish date.

Finally, look for insurance, license and permit responsibilities. The proposal should say who pulls permits, who schedules inspections and which licensed contractor is responsible for the work.

What we need from you to review it

If you want a construction-side read of a proposal, or a proposal of our own on the same basis, send your current drawings with their revision dates, your soils report, any selection list and the proposals you are comparing.

Frequently asked questions

What is an allowance in a construction contract?

An allowance is a set amount included in the price for an item you have not selected yet, such as tile, lighting or plumbing fixtures. If your final selection costs more, you usually pay the difference; if it costs less, the contract should say how the savings are handled. Always confirm whether an allowance covers material only or installation as well.

Why are two new home bids so different for the same plans?

Most gaps come from scope, not efficiency. One bid may include site work, utility connections or landscaping that the other excludes, or carry higher allowances for finishes. Line up the scope, allowances and exclusions of each proposal side by side, and add the excluded items to the lower bid before deciding which is actually less expensive.

Should I accept verbal changes during construction?

It is safer not to. Ask for every change to be written up with a description, a price and any schedule effect, then signed by you before the work proceeds. That record protects both sides, keeps the budget visible and avoids disputes at the end of the project about what was agreed and when.
