Biggest Remodeling Mistakes: Choosing a Contractor Based on the Lowest Bid

Quick Summary / Key Takeaways

• The "Total" Trap: A low total often masks missing categories like debris removal, permits, or finishing details.  

• 2026 Regulatory Shift: New California laws (SB 440) now regulate how change orders are handled—protecting you from "bait and switch" pricing.  

• Hidden Cost Drivers: Low bidders often use the "Hope Method," ignoring 2026 material tariff spikes and labor shortages until the project is underway.

• The Retention Cap: As of January 1, 2026, SB 61 caps retention at 5% for most private projects, preventing contractors from holding too much of your cash.  

• Leadership vs. Lump Sum: PMS Remodeling’s "Open-Book" model removes the incentive for contractors to cut corners to protect their margins.

In the 20+ years we’ve served the Chico community, we’ve seen one mistake repeat more than any other: a homeowner chooses a contractor because their number was the lowest.

It’s an understandable impulse. Remodeling is a major investment, and saving $10,000 or $20,000 on paper feels like a win. However, in the 2026 construction market, a bid that is significantly lower than the rest isn't a "deal"—it’s a risk.

Here is why choosing a contractor lowest bid mistakes Chico can derail your home and your finances.

1. The Anatomy of a "Low-Ball" Bid

When a bid comes in 15% to 30% lower than competitors, it usually isn't because that contractor found a "secret" supplier. It’s usually due to one of three things:

• The Vague Scope: The bid says "Renovate Kitchen." It doesn't mention the Chico building permit fee transparency, the cost of moving gas lines, or the Level 5 drywall finish you requested.

• The "Hope Method": The contractor is using old pricing, ignoring the material tariff impact on construction 2026. When the steel or lumber arrives at a higher price, they will stop work until you pay the difference.

2. New 2026 Laws You Need to Know

California has introduced new protections to combat predatory bidding. If you are comparing bids, look for these compliance markers:

SB 440: The Change Order Law

Starting in 2026, California SB 440 change order laws require a strict framework. Contractors must respond to change order claims within 30 days. Low bidders often rely on "Change Order Creep" to make their profit. Under the new law, disputed changes must go to non-binding mediation, which can stall your project for weeks if the bid wasn't accurate to begin with.  

SB 61: The 5% Retention Cap

Previously, it was common to hold 10% of the payment until the end. Now, SB 61 caps this at 5%. A low-bidder with poor cash flow will struggle with this cap, potentially leading to them abandoning the job when they run out of "front-loaded" cash.  

3. How to Compare Bids (The Right Way)

Don't just look at the bottom line. Create a "bid leveling" sheet.

• Are permits included? (The City of Chico fees aren't optional).

• Who pays for debris? (Dumpster fees in Butte County are rising).

• What are the "Allowances"? If one bid gives you $5,000 for appliances and another gives you $15,000, the first bid isn't "cheaper" it's just unrealistic.

Frequently Asked Questions

Why is the lowest remodeling bid a bad idea?

The lowest bid often indicates a "Hope Method" estimate that ignores 2026 material volatility, lacks proper insurance, or intentionally excludes essential tasks like permit management and site cleanup. These hidden costs of low remodeling bids usually surface as expensive change orders later.  

What are the new California contractor laws for 2026?

Two major updates are SB 440, which mandates 30-day responses and mediation for change order disputes, and SB 61, which caps "retention" (money withheld until completion) at 5% for private residential projects.

How do I know if a contractor's bid is too low?

If one bid is more than 15% lower than two other reputable quotes, it’s a red flag. Check for a vague scope of work, missing license numbers, or "allowances" for materials that are significantly below current Chico retail prices.

What should be included in a fixed-price remodel bid?

A professional bid should include a detailed scope of work, specific material specifications, permit responsibilities, a clear timeline, insurance verification, and a breakdown of "allowances" for items like tile and fixtures.

Can I fire a contractor for constant change orders?

Yes, but it depends on your contract. Under SB 440, there is now a clearer legal path to resolve these disputes. This is why having a detailed "Project Leadership" agreement is safer than a vague "Lump Sum" contract.
