Field notes / Homeowner guide
Compare contractor scopes on equal terms
Two proposals can describe the same goal while including very different work. Compare the boundaries, not just the bottom line.

In brief
Ask every bidder to respond to the same written brief and disclose exclusions and assumptions.
01
Create a common scope brief
Describe the spaces, intended changes, known existing conditions and desired finish level. Provide the same plans and photographs to each team. State whether design, engineering, permit coordination, protection and cleanup are expected or still undecided.
If a wall or system has not been investigated, call it unknown rather than presuming it is simple. A clear unknown invites a proposed investigation method.
Ask yourself
- Are all proposals based on the same drawings?
- What work is expressly excluded?
02
Read the line between included and assumed
Compare demolition, disposal, framing, mechanical and electrical work, finishes, site protection and final cleanup separately. Note whether a material is named, carried as a provisional allowance or supplied by the owner.
A proposal that says ‘as needed’ may leave a decision open. Ask what triggers the work, who decides and how a change would be priced. Do not assume a vague line includes every concealed condition.
Ask yourself
- Who supplies each fixture and appliance?
- Who coordinates trades and inspections?
03
Compare the proposed process
Request a sequence of milestones and identify decisions required before each one. Consider the plan for access, occupied spaces and documentation of revisions as part of scope, not as an afterthought.
California's CSLB publishes consumer guidance on home improvement contracts; review the written contract and the governing rules before signing. This guide is a comparison tool, not legal advice.
Ask yourself
- What document records the final scope?
- How will a change be approved before work proceeds?
04
Make differences visible
Build a simple comparison sheet with columns for included, excluded, allowance, owner-supplied and unresolved. Ask for clarification in writing on every row that differs.
A useful decision is not necessarily the shortest or longest proposal. It is the one whose assumptions and responsibilities you can understand before committing.
Ask yourself
- Which missing detail could affect several rooms?
- What must be clarified before comparing proposals?
A scenario to consider
Proposal A includes wall patching after electrical work; Proposal B lists electrical work but excludes finish repairs. Ask both teams to address the same finished condition before comparing them.
Planning scenario
Bring this to your conversation
- Send identical plans and goals to each team
- Mark included, excluded and provisional work
- Identify who orders and stores materials
- Ask how concealed conditions will be handled
- Read the written contract and ask for clarifications
One more question
How do I compare two contractor proposals?
Line them up item by item: what is included, excluded, provided by others or carried as an allowance. A lower total often reflects a narrower scope rather than a better price.
What must a California home improvement contract include?
Business and Professions Code § 7159 sets required contents, including the contractor's license number, a description of the work, the contract price, a payment schedule and required notices.
Can I compare proposals by total alone?
No. A total without aligned scope, allowances and exclusions is not an equivalent comparison.
