How Much Does It Cost to Build a House as an Owner‑Builder?

from Panelized Prefab Kit Home Building Show · host Landmark Home and Land Company

Episode 76: Thinking about building your own home and wondering what it will really cost? This episode shows you how to get an accurate owner‑builder budget without relying on unreliable “cost per square foot” charts, books, or AI guesses. Steve explains why the only numbers that matter come from real plans priced by real local contractors, and how a detailed, permit‑ready plan set lets subs give serious bids instead of guesses. You’ll learn the difference between hard costs (foundation, windows, roof, materials, labor) and soft costs (plans, engineering, permits), how Landmark’s one‑stop design and engineering package actually reduces change orders and surprises later, and where DIY work truly saves money versus where you’re better off hiring pros (especially for HVAC and other critical systems). Steve also breaks down how owner‑builders can realistically use their own skills plus Landmark’s detailed plans and support to manage subs, control costs, and avoid underestimating key items like windows, foundations, and code‑driven requirements such as egress and tempered glass — turning a vague “I want to build a house” into a confident, funded, line‑item budget.

Transcript: Steve Tuma: You know, we’ve been doing this 32 years — almost 33 years. We’ve seen an amazing amount of things. But every once in a while, you get a curveball. The thing is, we have the resources to get you the answer of how it applies to your particular project on your building site. Interviewer: Hello everyone, and welcome to Episode 76 of the Panelized Prefab Kit Home Building Show. With me today, as he normally is, is the President and Founder of Landmark Home and Land Company, a company which has been helping people build their new homes where they want, exactly as they want, nationwide and around the globe since 1993 — Mr. Steve Tuma. Steve, how’s it going, pal? Steve Tuma: It’s going great again — another day of helping people figure out how to build houses. We’re getting more and more customers that are coming back and doing some duplexes or investment properties. Interviewer: Well that’s good. Steve Tuma: Yeah, which is cool. Some new customers, some that built with us years ago that are like, “Hey, it’s time to do an investment property.” It’s kind of cool. It’s similar in process, and then other times it’s a little different, depending on codes or where they’re building or site conditions. Interviewer: Return customers can never be bad. Steve Tuma: It’s always fun. It’s just kind of cool when you get a call out of nowhere and they say, “Hey Steve, remember me?” I’m like, “Yeah,” reminisce for a while on the houses, and move on to help them with their new projects. Interviewer: Better than you saying, “No, I have no idea who you are.” Steve Tuma: Yeah, no! Interviewer: I thought we’d talk today about a subject that’s on the minds of potential homeowner‑builders — and just about anybody these days, actually — and that’s the question of cost. The cost of living in general is so high these days, but for our purposes I thought we’d talk about the cost of building a home. Can we do that? Steve Tuma: Yeah. Well, it’s kind of interesting because a lot of people want to be an owner‑builder because of the savings. They can do some work so they don’t have to pay for someone else to do it. And then also, that savings — if they have a mortgage — saves considerably on their mortgage and the interest they pay over the life of...
