Adding square footage lets the tool compute true cost per square foot for each bid — the number that makes different-sized proposals comparable. Everything runs in your browser; nothing is saved or sent.
Your bids, compared
Questions to take back to each contractor
Generated from each bid's unmarked categories. Firm written answers — ideally priced — are what turn different bids into one honest comparison.
This compares only what you enter. A missing checkmark means the item wasn't marked as included — verify it in the actual proposal, because "assumed included" is how budgets grow. A bid that includes everything isn't automatically the best one; it may simply be the most complete, which is its own kind of good sign. For what each line means, see our bid-comparison guide and contractor red-flags checklist.
The nine scope categories are the ones most often excluded from ADU construction proposals — the same list in our bid-comparison guide and soft-costs guide, drawn from how ADU bids are actually written. This tool doesn't estimate prices or judge fairness; it structures your own numbers so scope gaps become visible. It isn't a bid, an appraisal, or a recommendation of any contractor — the licensed contractor you choose is responsible for their own scope and pricing.
