Read the Exclusions Page First

Most people read a bid from the front: the total, then the line items, then the fine print if there's time. I'd flip that. The exclusions page tells you what the bid costs by telling you what it doesn't cover, and it's usually the fastest way to understand what a number really means.

What a complete bid should include makes the case for having exclusions in one place. This piece is about what to do once you have them.

What's commonly excluded

Exclusions tend to fall into a few groups. None of these is unusual to see on a custom home bid, and seeing them excluded isn't a red flag. It just means the cost lives somewhere else, and you need to know where.

Site and utilities. Rock excavation, imported fill, retaining walls beyond a set height, utility runs past a set distance, tap fees, well and septic.

Permits and fees. Building permit, plan review, impact fees, HOA design review fees and deposits.

Outside the house. Landscaping, irrigation, hardscape, driveway paving, snowmelt, fencing.

Inside, but not "construction." Window coverings, appliances, furniture, art lighting, low-voltage and audio-visual, security systems.

Insurance and conditions. Builder's risk insurance, winter conditions, temporary heat beyond a set period.

Reasonable exclusions vs. ones worth a question

An exclusion is reasonable when the item truly isn't part of the builder's work, or when its cost can't be known yet. Tap fees are set by the utility, so a builder may leave them for you to pay directly. Rock can't be priced until someone digs.

An exclusion is worth a question when it's something every other builder included, or something the house can't be finished without. If two bids include the driveway and the third excludes it, the third bid isn't necessarily low. It may just be organized differently. But you can't compare it until you price the driveway.

Also watch for exclusions that quietly undo part of the scope. "Excludes final grading" on a sloped lot, or "excludes ice and water shield beyond code minimum" in snow country, can change what you're actually getting.

Finding all of them

Exclusions don't always live on the exclusions page. They hide in line-item notes ("excludes hardware"), in the footer of a trade section, in the cover letter, and in assumptions ("assumes no rock"). An assumption is an exclusion in disguise: if it turns out to be wrong, the cost isn't in the price.

Before you compare bids, go through each one page by page and pull every exclusion and assumption onto one list. It takes an evening. It's the most useful evening you'll spend on bids.

Price the gaps yourself

Once you have the list, decide three things for each item: is it needed at all, who's covering it, and roughly what it costs. Get a quote where you can, or a reasonable range. Then add those numbers to the bid before you compare.

Here's what that can look like. Illustrative numbers.

Item	Bid A	Bid B
Bid total	$1,180,000	$1,215,000
Driveway (excluded in A)	+$30,000	included
Builder's risk insurance (excluded in A)	+$6,000	included
Window coverings (excluded in both)	+$18,000	+$18,000
Adjusted for exclusions	$1,234,000	$1,233,000

A $35,000 gap became a $1,000 gap. That doesn't make the bids equal, because allowances and assumptions still need the same treatment. But now the comparison is about the same house.

Items excluded from every bid don't change the comparison, but they still belong in your budget. Window coverings, appliances, and landscaping are real money whether a builder carries them or not. The all-in budget is where they go.

Questions worth asking

• Is every exclusion listed in one place, or are some in line-item notes and assumptions?
• For each exclusion, who do you expect to cover it, and do you have a rough number?
• Which assumptions, if wrong, would change the price, and how would that be billed?
• Is there anything excluded here that you'd normally include on a house like this?
• Can the exclusions list be attached to the contract as written?
