Contact Ellery ADU Studio Huntington Beach - Free ADU Estimate in Huntington Beach
Call (562) 263-3350 to schedule your free ADU estimate in Huntington Beach. When you reach us, you’ll speak with a live coordinator who connects you directly with our local team. There’s no hard sell, no pressure to decide on the spot, and no fee for the assessment. We’ll ask about your property, your goals, and what you’ve already learned about ADUs, then we’ll find a time that works for your schedule.
What Happens When You Call
Step 1: We answer and listen. A live coordinator picks up, takes your information, and connects you with a local ADU specialist who knows Huntington Beach zoning. We’ll ask about your lot size, your existing structure, and whether you’ve checked your city’s preliminary zoning. That first call usually takes ten to fifteen minutes.
Step 2: We schedule a site assessment. We visit your property in Huntington Beach to measure setbacks, check utility access, and photograph conditions that affect design. You’ll get a real arrival window, a named specialist, and a text when we’re on the way. That’s Haven Standard Clause 2.
Step 3: You receive a written estimate. Within three business days of the assessment, we deliver a line-item quote: design fees, permit costs, construction scope, and project timeline. The price is flat. The scope is fixed. That’s Haven Standard Clause 1: Have it in writing before anyone starts.
Step 4: We build to the drawings. Once you approve, we handle the permit set, submit to Huntington Beach planning, and build under a single contract with one point of responsibility. No designer blaming the builder, no builder blaming the designer. Photos and readings at every phase. That’s Haven Standard Clause 4.
Why Huntington Beach Homeowners Call Us First

- We’re local to Huntington Beach. Our team lives and works in the same ZIP codes we build in. We know the difference between R-1 and R-2 zoning in this city, and we’ve navigated Huntington Beach’s specific utility connection requirements more times than we can count.
- Every pro working under our name is required to hold the license and insurance California requires. We verify it before they step on your property, and we keep license numbers on file. Haven Standard Clause 3 means verified crews, not just promised ones.
- Our pricing is flat and written. The estimate you sign is the price you pay. No door upsells, no “while we’re in here” additions, no change orders unless you change the scope yourself. Haven Standard Clause 5: no surprises.
- We leave evidence on every job. Photos of what we found, readings we took, conditions we documented. You get the file. That’s Haven Standard Clause 4, and it’s how we prove we built what we said we’d build.
Our Service Area Around Huntington Beach
We design and build ADUs throughout Huntington Beach and the surrounding communities. Most of our assessments happen within a day or two for properties in Fountain Valley, Westminster, Seal Beach, Costa Mesa, and Garden Grove. For Midway City, Stanton, Santa Ana, Los Alamitos, Rossmoor, and Cypress, we typically schedule within the same week. If you’re near these areas and don’t see your city listed, call anyway. We’ve taken on projects in unincorporated pockets of Orange County that most builders won’t touch, and we’ll tell you honestly whether your property fits our model.

We’ll walk you through it. Call (562) 263-3350 when you’re ready.
