Never tell your builder your budget. Hire an architect first, have the architect draw a complete set of plans, and then ask at least three builders to bid on those same plans. That order is how you find out what your home really costs, and it protects your money. In the video above I walk through why. I lost my own home in the Eaton fire, and since then I have helped rebuild $65 million worth of homes in my hometown of Altadena.

This guide is for Altadena homeowners who are about to make that first call to a builder. It covers the biggest mistake new homeowners make when they rebuild, and the order of hires that avoids it. It is the same playbook informed wealthy homeowners use to spend less and put the difference into the house.

Why should you never tell your builder your budget?

Builders usually open with one question: "So, what's your budget?" It sounds harmless, which is why most people answer it. But nobody walks into a car dealership, announces they have $40,000, and then asks how much the car costs. Your first conversation with a builder works the same way. If you tell him your number, you will overpay on your build, the same way that car buyer would.

Why do three builders give you three different prices?

The price you hear depends on what the builder is pricing. Suppose you tell three builders you want a 2,000 square foot home. All three can give you completely honest numbers, and those numbers can still be hundreds of thousands of dollars apart. They are not pricing the same home. Without a complete set of plans, which are the detailed drawings that show exactly what will be built, there is no house to price yet. It is only an idea, and every builder has his own. Once an architect defines your home with complete plans, the builders will still give you different numbers, but now the differences mean something, because everyone is pricing the same house.

What is design-build, and why is it risky after a fire?

I have sat with a lot of fire-impacted families here in Altadena, and I understand the pull. You have been through a lot, you have a budget to rebuild, and your first instinct is to find a builder right away. A builder here usually means a general contractor, the company that manages the construction and hires the trades. But the safest way home is not calling a general contractor first.

Most large construction projects have the same three people: a builder, an engineer and an architect. The architect designs the home and draws the plans. The engineer does the math that makes those plans safe to build. When the builder is the first person you hire, he brings in the architect and the engineers as part of his team. They design the whole house together, and he hands you one price for all of it. That is called design-build.

A typical design-build sale has four steps:

  • He asks about the home you want and your budget. You say 2,000 square feet, three bedrooms, two baths, under $900,000.
  • He comes back with $700,000. He calls it a ROM, short for rough order of magnitude, which means a ballpark figure.
  • You are thrilled to be way under budget, so you skip the fine details and sign.
  • Months later, the plans and engineering are done, and the builder can finally work out what your house really costs. It is $850,000, maybe $900,000, maybe a little more. That is just about the budget you first told him.

Nobody has to lie for this to happen. The early number was a ballpark, and the real number could only come once the plans were finished. The problem is that you will never know if your house would have cost less.

Why is it so hard to get a second quote from your builder?

A second quote is a price from a different builder for the same job. By the time the plans are done, you have spent months designing with your builder and paid for the drawings. He knows the plans inside and out, you have made hundreds of decisions together, and you like these guys. Asking for another price feels foolish. Walking away does not feel like getting a second quote. It feels like breaking up with someone who has done nothing wrong.

That is the real cost of the ballpark figure. It did something a ballpark figure should never do: it locked you in with a builder months before you knew the actual price. Treat a rough number as a guess, not a price.

Design-build vs design-bid-build: what changes if you hire an architect first?

In design-build, the builder's team designs the house and gives you one price. In design-bid-build, you use the same three people in a different order. You hire the architect first, and the architect works directly for you. Over about six months, the architect drafts the plans, sends the math off to the engineer, and hands you the blueprint for the exact home you want.

Now you can take those blueprints to three different builders and ask each for a bid, which is a builder's written price to build those plans. The builders compete against each other. These are competitive bids for a home rebuild, and you can only get them once complete plans exist. The bids may still come in wildly different, but that now works for you, because all three builders priced the exact same plans. You can see who is padding their numbers, who charges more for what, and who is bidding low on purpose just to win the contract. Even if the bid you pick comes out at $835,000, you know without a doubt that no one took advantage of you.

Is hiring the architect first enough to protect your budget?

Not by itself. The best example I have is about selling a house, not building one. A friend of mine had a neighbor whose own real estate agent stabbed her in the back. After the closing, the buyer's agent pulled up, and my friend asked him how the deal went. He was thrilled. He said, "I've worked with that listing agent for 10 years. I just asked him what the lowest price the seller would actually take, and he told me."

The listing agent, who works for the seller, gave away all of her leverage. The buyer might easily have paid tens of thousands of dollars more, and the seller had no idea. She thought the world of her agent. To her, it was the biggest sale of her life. To the agent, it was just another transaction, and the two agents had dealt this way for years. You scratch my back, I'll scratch yours.

The moral applies to a rebuild. If you hire the builder first, so much trust builds up inside his team that you will believe they have your best interest at heart. If you hire the architect first, you can ask for a referral and then add three other builders you find on your own. That mix gets you the best competitive bid.

What should you do before you talk to a builder about money?

The order of your hires is what protects you. This is the sequence that protects your Altadena rebuild:

  • Do not tell any builder your budget.
  • Hire an architect first. The architect works directly for you.
  • Let the architect finish a complete set of plans.
  • Ask the architect for a builder referral, then find three other builders on your own.
  • Give all of them the same plans and ask for bids.
  • Compare the bids, and look for who is padding, who charges more for what, and who is bidding low just to win.

The builder's question, "So, what's your budget?", will come. Now you know not to answer it. You will probably do this just once in your life, while everyone you are about to depend on does it every single day. That experience gap is real. But you do not need to know more than the professionals. You only need to know the process that protects you.
