Before You Hire a Single Contractor, Read This.
Most San Diego homeowners overpay by $30,000–$50,000 on their construction project — not because they're careless, but because they didn't know what to look for. This free guide shows you the 7 most common traps contractors use to pad their bids, and exactly how to protect yourself before you sign anything.

Getting a building permit approved is a win. But the moment that permit hits public record, your phone starts ringing. Contractors, lead gen services, referral programs, everyone wants a piece of your project.
The problem isn't that all contractors are dishonest. The problem is that you can't tell the difference between a transparent builder and one who buries $30,000 in fees until you're three months in and you've already signed.
The traps aren't obvious. They're buried in line items labeled "allowances," "site conditions," and "project management." They're left out of the initial bid entirely, then delivered as change orders once you're locked in.
This guide exists because homeowners deserve to walk into that first conversation knowing exactly what to look for.
The "Impact Fee Shock" — A single 50 sq ft design mistake that can trigger a $10,000+ city fee. Page 2 shows you how to catch it before permits are finalized.
The Missing Trenching Trap — How a $15,000 utility bill appears in month one after you're no longer able to walk away. It's left out of bids on purpose.
The Middleman Markup — Why you may be paying a 20–40% premium to a General Contractor who isn't swinging a hammer. And what the alternative looks like.
The "Allowance" Game — How artificially low line items turn into massive change orders mid-build. The red flag is hiding in plain sight on every bad bid.
The Equipment Rental Padding — How daily rental fees quietly inflate your invoice by $8,000–$15,000 on a standard ADU or addition.
The 5 Questions That Expose Everything — Ask these before you receive a single bid and you'll know within 10 minutes whether a contractor is worth your time.

BuilderMatch SD is a private matching service for San Diego homeowners and developers who've pulled a building permit. We've built this guide - and this service - because we've seen what happens when homeowners walk into contractor negotiations unprepared.
We're not a contractor. We're not a lead gen platform. We connect permit holders with vetted, local wood-frame builders from our private network, completely free to you. We only earn a referral fee from the builder, and only after you hire them.
This guide is something we give to every permit holder we work with. Whether you use our matching service or not, we want you to be protected.
