Contact Ellery ADU Studio Chino Hills - Free ADU Estimate in Chino Hills
Call us at (951) 456-4467 to schedule your free ADU estimate in Chino Hills. When you reach our live coordinator, you’ll get a real person who listens to what you’re planning, checks availability for an on-site assessment, and books a time that works for your schedule. There’s no hard sell, no deposit required to get on the calendar, and we’ll often have a slot within the same week.
What Happens When You Call
Step 1: We answer and listen. Our coordinator picks up during business hours, takes down your address in Chino Hills, and asks what you’re considering - a garage conversion, a backyard cottage, or an attached addition. You’ll know in two minutes whether we’re the right fit.
Step 2: We schedule your on-site assessment. Nadia Ellery or a senior estimator visits your property, measures the buildable area, checks setback lines against Chino Hills’ current ADU ordinance, and photographs the existing conditions. This visit is free and carries no obligation.
Step 3: You receive a written, line-item estimate. Within 48 hours, we email a fixed-price proposal that separates design, permit fees, site work, and construction. Clause 1 of the Haven Standard says the price is flat - no change orders unless you change the scope.
Step 4: We permit, build, and document. Once you approve, we produce the architectural set, pull permits through San Bernardino County, and build to the drawings. Every phase gets photo documentation under Haven Standard Clause 4, and you receive the full record at final walkthrough.
Why Chino Hills Homeowners Call Us First
- We know the local terrain. Chino Hills’ hillside lots, fire zone requirements, and varying soil conditions mean an ADU plan that works on Butterfield Ranch Road won’t work on Soquel Canyon Parkway. We’ve assessed properties across every neighborhood in Chino Hills and know which corners of the city trigger geotechnical review.
- Every pro is properly credentialed. Under Haven Standard Clause 3, every designer, drafter, and tradesman working under our name is required to hold the license and insurance California requires for their role. We verify it before they step on your property, and their license numbers appear in your contract.
- The price you see is the price you pay. Haven Standard Clause 1 requires a flat, written price before anyone starts. No “allowances” that balloon, no ” unforeseen conditions” surcharges buried in fine print. If we missed something in our assessment, we absorb it.
- We guarantee the workmanship. Our build warranty covers structural defects and systems failures for the period specified in your written contract. Haven Standard Clause 5 means no surprises - if we installed it, we stand behind it.

For neighboring cities, our response times are: Chino and Diamond Bar within a week; Yorba Linda, Anaheim, and Corona within 7-10 days; Pomona, Eastvale, Montclair, Ontario, Rowland Heights, and Upland within two weeks.

Frequently Asked Questions - Booking & Estimates
Yes. The on-site assessment and written proposal cost nothing, and you’re under no obligation to hire us. We believe you can’t make a six-figure decision without knowing the real number, so we put it in writing before you commit. Call (951) 456-4467 to schedule yours.
We typically book on-site assessments in Chino Hills within 3-5 business days of your call. During peak spring and summer seasons, that may stretch to a week. The coordinator will offer specific slots when you call - no vague “we’ll get back to you.” Call (951) 456-4467 to check this week’s availability.
No. Our assessment fee structure does not change based on day or time. However, our operating hours are Monday through Friday 7:00 AM to 7:00 PM, and Sunday 7:00 AM to 7:00 PM. We are closed Saturday. Evening assessments can sometimes be accommodated within these hours - ask the coordinator when you call.
Your property address, a rough idea of the ADU type you’re considering (detached, attached, or garage conversion), and any known constraints - easements, slope, or HOA rules. If you have a survey or recent plot plan, mention it. The more we know upfront, the more precise your estimate window will be. Call (951) 456-4467 when you’re ready.
We accept personal check, bank transfer, and major credit cards. For ADU projects, payment is structured in draws tied to permit milestones and construction phases - never a large upfront deposit. The exact schedule appears in your written contract under Clause 1. Call (951) 456-4467 and we’ll walk through typical payment timing for a project your size.
