Why Tustin Homeowners Choose Holloway ADU Builders for ADU
We’ve been building accessory dwelling units across Orange County since 2016. Homeowners in Tustin, North Tustin, Irvine, Santa Ana, and the surrounding neighborhoods keep coming back to us for one reason above all: we treat an ADU like the major investment it is, not a quick flip. That means fixed pricing in writing before work starts, a real warranty, and a team that knows how Tustin’s planning department and HOA overlays actually work. If you’re comparing ADU builders, we welcome the comparison.
6 Reasons We’re Tustin’s Top ADU Company
A Decade of Local ADU Experience
Holloway ADU Builders has been building in Tustin since 2016. That’s ten years of navigating Orange County setbacks, utility easements, and school district impact fees. We know which lots in the Tustin Legacy area qualify for detached units and which older parcels near Old Town need a little more patience. That kind of local knowledge isn’t something you can buy on day one.
A Strong Local Reputation
Our past clients in Tustin and nearby cities have taken the time to leave us strong reviews across Google and the major home services platforms. We don’t need to shout about it because we’d rather you read what your neighbors said themselves. When a homeowner in North Tustin tells a friend in Villa Park that we showed up on time and held our price, that’s the only marketing that matters.
Licensed and Insured, the Right Way
We carry the California contractor’s license and insurance coverage required for residential ADU construction. Every professional working under the Holloway name is required to hold the license and insurance their state requires. We pull permits on every project, and we don’t consider a job done until the final inspection passes. You’re welcome to verify our credentials before you sign anything.
Real Brand Expertise: Cover, Dvele, and More
We’ve built with prefab and panelized systems from Cover and Dvele, which means we can talk honestly about what those products do well and where they don’t fit. Some Orange County lots are perfect for a panelized build that goes up in weeks. Others need a custom stick-built approach. We’ll give you a straight answer about which route makes sense for your property, your budget, and your timeline in Tustin.
Transparent, Fixed Pricing
Every estimate we provide is free, written, and line-itemed. The price we quote is the price you pay unless you change the scope of work. No vague allowances, no mid-project change orders that surprise you. When you compare ADU builders in Tustin, ask everyone one question: will this number hold? Ours does.
A Warranty We Put in Writing
We stand behind our ADU construction with a workmanship warranty, spelled out in the contract before work begins. If something we built fails because of how we built it, we’ll make it right. That’s not a sales line. It’s a commitment we’ve been keeping for Tustin homeowners since 2016.

When you hire Holloway ADU Builders, here’s what you get. Free estimates with detailed, written, line-by-line pricing. A fixed contract with no surprise change orders unless you request a scope change yourself. Permits pulled and inspections passed before we call the job complete. A workmanship warranty in writing. And a live coordinator who answers your calls during business hours and connects you with the local team working on your property. If something isn’t right, we want to hear about it immediately, not after the fact. Our hours in Tustin are Monday through Friday 7 AM to 7 PM and Sunday 7 AM to 7 PM. We are closed Saturdays.
