Short answer: remodel bids are only comparable when they price the same scope, the same allowances, the same permit path and the same exclusions. Before comparing totals: send every bidder one written scope sheet; ask them to price your allowance amounts rather than their own; ask each to list what is excluded and who handles the permit; then put the bids side by side in a leveling table and add back anything a bidder left out. CSLB recommends getting at least three bids and checking references and licenses (CSLB). Its contract guide Terms of Agreement advises describing materials in detail, by brand, model, color and quantity, which is also what makes bids comparable.

Why quotes differ so much
A homeowner who finished a kitchen on budget wrote that quotes 'wildly varied'. They kept collecting quotes, avoided major construction, and declined extras such as pendant lights that several contractors wanted to add. In a Bay Area garage-conversion thread, an owner reported per-square-foot estimates that varied widely between contractors. These are individual accounts, not market data, and the figures in the worked example below are invented for comparison, not Bay Area price estimates. The underlying reasons for spread are consistent, though:
- Different scope: one bid includes drywall repair, painting and a new subfloor; another assumes they won't be needed.
- Different allowances: a bid with a low tile allowance can look cheaper but may leave too little for the products you intend to choose.
- Different permit assumptions: one bidder priced plans, permit fees and inspection-driven items; another did not.
- Different risk pricing: fixed-price bidders add contingency for unknowns; others exclude unknowns and bill them later.
- Different business models: company size, overhead, insurance, workload and how much the contractor wants the job.
Step 1: write one scope sheet
A one- to three-page document that every bidder receives:
- Demolition and protection: what is removed, how occupied areas are protected, debris removal.
- Layout: same or changed; a dimensioned sketch if changed.
- Structure: any wall removal, and who provides engineering.
- Plumbing: fixture count and locations, and whether lines are moved.
- Electrical: new circuits, lighting, receptacles, panel capacity check.
- Ventilation: range hood or bath fan, ducted to the exterior.
- Finishes: cabinets, countertops, tile, flooring, paint, with your selections or allowance amounts.
- Permit: who applies, whether plans are needed, and who pays fees.
- Schedule: preferred start and any fixed constraints.
Step 2: fix the allowances
Tell every bidder the allowance amount for each unselected category, for example tile at a stated dollar figure, material only, and ask them to use your number. This removes an avoidable source of difference. See allowances and price changes.
Step 3: ask the same questions of everyone
| Question | Why it matters |
|---|---|
| What is excluded? | Exclusions are where low bids become high final costs |
| Who handles plans, permit and inspections, and is that priced? | Permit work and required upgrades vary by jurisdiction |
| How are hidden conditions priced: unit prices, T&M with a cap? | Determines your exposure after demolition |
| Who will be on site, and which trades are subcontracted? | Affects quality control; a subcontractor list must be available on request where subs are used |
| What does the payment schedule look like? | Must respect the down payment cap and track completed work |
| What warranty is offered, in writing? | Compare substance, not slogans |
| What is the realistic start date and duration? | A low bid with a start date months away may not suit you |
Step 4: level the bids, a worked example
Hypothetical bids, for method only. The figures are illustrative, not cost guidance.
| Item | Bid A | Bid B | Bid C |
|---|---|---|---|
| Total as submitted | $62,000 | $48,000 | $71,000 |
| Tile allowance used | Owner's figure | Lower than owner's figure (+$1,500 to match) | Owner's figure |
| Permit and plans | Included | Excluded (owner estimate +$3,000) | Included |
| Drywall repair and paint | Included | Excluded (+$2,500 estimate) | Included |
| Hidden-condition pricing | Unit prices listed | 'T&M at our rates', no cap | Contingency built in, unit prices for structure |
| Leveled total (before unknowns) | $62,000 | $55,000 | $71,000 |
After leveling, B is still lowest, but by less, and it carries uncapped exposure on hidden conditions. C is highest but includes a contingency that A and B leave to change orders. The decision now turns on substance: references, license and insurance status, the payment schedule, how each handles unknowns, and who you trust to communicate. Ask B to cap its T&M exposure and to price the excluded items. If it declines, that tells you something too.
Step 5: check the bidder, not just the bid
- License: active, correct classification, name matching the bid, on the CSLB lookup. Look at the workers' compensation status and bond history too.
- References: recent, similar projects. Visit one if you can.
- Insurance statements: the contract must disclose commercial general liability and workers' compensation status (BPC § 7159). Ask for the insurer's contact details to verify.
- Contract draft: ask for a sample contract with the bid. Missing statutory notices are a warning sign. See our contract checklist.
Red flags in bids
- A single line total with no breakdown or scope description
- Deposit requests above $1,000 or 10% of the price, whichever is less, absent the specific blanket bond exception
- 'Permit not needed' for work that clearly involves plumbing, electrical or structural changes, without checking
- Pressure to sign quickly, or a discount that expires today
- Vague allowances such as 'tile: TBD'
- No license number on the bid
Edge cases
- Only one bidder is available for a specialty scope or a tight schedule. Ask for an itemized breakdown and compare its line items with published local permit requirements and your own allowance research.
- A design-build firm prices as the design develops. Compare its design fee and early estimate against a designer-led route. See designer vs design-build.
- Bidders push upgrades. Keep your scope sheet as the base bid and ask for upgrades as separately priced alternates.
Bay Area applicability
Bid differences often trace back to permit assumptions, and permit requirements combine state codes with local amendments and procedures. Building departments apply the 2025 California codes, effective 1 January 2026, through their own submittal and inspection practices. Some cities also attach requirements to remodel permits. Pleasanton's kitchen handout, for example, describes replacing noncompliant plumbing fixtures before final approval where the applicable existing-building rules require it. Ask each bidder which permit-triggered items they included for your specific city.

Questions that come up next
How many bids should I get for a remodel?
CSLB recommends at least three, together with license checks and references. More bids help only if each prices the same scope, allowances and permit path.
Why are my kitchen remodel quotes so different?
Usually because the bids are not pricing the same job: different scope, allowances, permit assumptions, exclusions and approaches to hidden conditions. Leveling the bids reveals the real differences.
Should I take the lowest bid?
Only after leveling. Add back excluded items and allowance shortfalls, and consider how hidden conditions are priced, license and insurance status, references and the payment schedule.
What should a remodel bid include?
A scope description, materials or allowances with amounts, exclusions, permit responsibility, a payment schedule within California's down payment limit, an estimated schedule, and the contractor's license number.
