Contact Sunstone ADU Builders – Free ADU Estimate in Aliso Viejo
Ready to talk about your ADU? Call us at (855) 949-1913 and you’ll reach a live coordinator who connects you with our local Aliso Viejo team. We’ll answer your questions, walk through your property goals, and schedule a no-pressure assessment at your convenience. No hard sell, no obligation. Just straight answers from people who’ve built ADUs across Orange County since 2011.
What Happens When You Call
Step 1: You call (855) 949-1913. A live coordinator answers during business hours and asks a few quick questions about your property, your timeline, and what you’re hoping to build. You won’t sit through a long phone tree or get bounced between departments.
Step 2: We schedule your free on-site assessment. One of our ADU specialists visits your Aliso Viejo home to measure setbacks, check utility access, and talk through what’s actually feasible on your lot. This is where we get into the real details: zoning, drainage, access for equipment, and the smartest placement for your unit.
Step 3: You receive a written line-item estimate. Within a few days, you’ll have a detailed proposal with transparent pricing, a clear scope of work, and a realistic construction timeline. No vague allowances. No “we’ll figure it out later” pricing. Every line item is spelled out so you can compare and plan.
Step 4: We build your ADU and keep you informed. Once you approve the estimate, our crew handles permits, inspections, and construction. You’ll get regular progress updates, and we don’t disappear between milestones. Questions come up? You call the same number and we answer.
Why Aliso Viejo Homeowners Call Us First
- Local ADU expertise since 2011. We’ve worked through Aliso Viejo’s specific setback requirements, hillside lot challenges, and HOA review processes. When a plan reviewer asks about drainage on a sloped lot near Wood Canyon, we already know the answer.
- Licensed and insured, every pro on the job. Everyone working under the Sunstone name is required to hold the license and insurance California mandates for their trade. We verify credentials before a single crew member steps onto your property.
- Fixed pricing with no hidden fees. The estimate you approve is the price you pay. Change orders only happen if you request a change. We don’t surprise homeowners with “unforeseen conditions” line items after excavation starts.
- A workmanship warranty you can actually use. We stand behind our builds and respond when something needs attention. If an issue comes up after you move a tenant in, you call us and we address it. That’s how we’ve earned repeat referrals across South Orange County.
Our Service Area Around Aliso Viejo
We build ADUs throughout South Orange County, including Laguna Woods, Laguna Hills, Laguna Beach, Mission Viejo, Ladera Ranch, Lake Forest, San Joaquin Hills, Coto De Caza, Rancho Santa Margarita, Irvine, and Foothill Ranch. Each area has its own planning quirks, and we’ve navigated most of them. If you live just outside these cities, call anyway. We’ll let you know within minutes whether we can help.
Frequently Asked Questions – Booking & Estimates
Yes. Your on-site assessment and written line-item estimate cost you nothing. We treat it as our chance to earn your business, not a billable consultation. Call (855) 949-1913 and we’ll schedule it at a time that works for you.
We schedule assessments Monday through Friday between 7:00 AM and 7:00 PM, and Sundays during the same hours. Most Aliso Viejo homeowners get an appointment within the same week they call. Tell us what works and we’ll make it happen.
No. Our standard hours include Sunday availability and evenings until 7:00 PM Monday through Friday, and there’s no surcharge for booking during those windows. The price you see on the estimate is based on the work itself, not the day of the week.
Helpful items include your property address, the approximate size of ADU you’re considering, and a rough sense of your timeline. Don’t have all that? Call anyway. We’ll guide you through the conversation and fill in the gaps during the on-site visit.
We accept standard payment methods including checks, bank transfers, and major credit cards. Payment schedules are tied to project milestones, so you’re never paying far ahead of work completed. We walk through the schedule on your written estimate so there are no surprises.
