Contact Guest House ADU Builders – Free ADU Estimate in Westminster
Talk to a real person about your ADU project by calling (833) 863-7015 today. When you call, you’ll speak with a live coordinator who connects you with our Westminster team, not a labyrinth of voicemail menus. We’ll answer your questions about design, permits, timelines, and cost, and if it makes sense, we’ll schedule a free on-site assessment with no obligation and no pressure.
What Happens When You Call
We’ve kept the process straightforward because we know calling a builder for the first time feels like a big step. Here’s exactly what to expect.
Step 1: You call (833) 863-7015. A live coordinator answers during our office hours, Monday through Friday 7:00 AM to 7:00 PM and Sunday 7:00 AM to 7:00 PM. You’ll describe your property and what you have in mind, whether that’s a detached backyard unit, a garage conversion, or something you haven’t fully figured out yet.
Step 2: We schedule a free assessment. We’ll find a time that works for you and send someone from our Westminster team to walk your property, check setbacks, access, utility locations, and the specific conditions that affect ADU feasibility in your neighborhood. This visit usually takes under an hour.
Step 3: You receive a written estimate. Within a few days of the site visit, we’ll deliver a detailed, line-item written estimate so you can see exactly where every dollar goes. No vague ballpark figures, no surprise change orders later, and a fixed price you can plan around.
Step 4: We build your ADU. Once you approve the estimate and permits are pulled, our crew handles the construction from start to finish. We coordinate inspections, keep the site clean, and don’t consider the job done until you’ve walked through the finished unit with us and signed off.
Why Westminster Homeowners Call Us First
- We know Westminster’s ADU rules from years of local work. Our company has been building in Southern California since 2011, which means we’ve navigated the city’s planning process, setback requirements, and permit flow enough times to anticipate issues before they delay your project. This saves you real time and real money compared to a builder who has to learn Westminster’s process on your dime.
- Every pro working under our name is required to hold the license and insurance their state requires. We don’t ask you to take our word for it, we make sure the people on your property are properly credentialed before they ever set foot on site. That’s a requirement, not a talking point.
- Fixed pricing with no hidden fees and no change orders. The estimate we give you is the price you pay, unless you decide to change the scope yourself. We put every line item in writing specifically so you never get a surprise invoice after the work starts.
- Workmanship warranty on the finished ADU. We stand behind what we build. After the final inspection passes and you have your certificate of occupancy, our relationship doesn’t end. If something isn’t right, we want to know about it and we’ll make it right.

Frequently Asked Questions – Booking & Estimates
Yes. The on-site assessment and written estimate are completely free whether you hire us or not. You’ll get a detailed line-item document you can keep and compare against other builders, and we won’t pressure you to commit on the spot. Call (833) 863-7015 to schedule yours.
We work within our office hours of Monday through Friday 7:00 AM to 7:00 PM and Sunday 7:00 AM to 7:00 PM, and we’ll schedule your free assessment for the earliest available slot that fits your calendar. The exact timing depends on how many assessments are already booked, but we’ll give you a confirmed time when you call.
No. Our rates are the same regardless of which day we’re on your property, and our office hours already include Sunday. You won’t see a weekend surcharge or an after-hours fee on your estimate.
Not much. It helps if you know your property’s lot size, the approximate location where you’re thinking about the ADU, and whether you have a garage or existing structure you might want to convert. If you don’t have those details handy, don’t worry. That’s exactly what the free site assessment is for. Call (833) 863-7015 and we’ll walk you through it.
We accept standard payment methods including check, bank transfer, and major credit cards. We’ll go over the payment schedule with you before any work begins so you know exactly when each payment is due and what it covers. For a specific quote for your Westminster property, call (833) 863-7015.
