Every price we give is written and locked before work starts, per Haven Standard Clause 1 - no exceptions, no surprises.
Current Offers
Free Second Opinion on Any Written ADU Estimate
Already have a quote from another design-build firm or a standalone architect? We’ll review the full scope, the permit strategy, and the line-item pricing, then tell you where the gaps are. This isn’t a sales pitch disguised as advice - it’s a genuine second look at whether your slab was actually inspected, whether utility tie-ins were priced, and whether the city of Anaheim’s fire separation requirements were addressed.
Valid through December 31, 2026. Mention this offer when you call (657) 366-5740.
365-Day Done Right Promise - Written Guarantee on Every Project
This isn’t a discount; it’s a structural protection most Anaheim ADU builders won’t put in writing. If your finished ADU doesn’t match the permitted drawings, we make it right, and that promise is documented before your project starts. We’ve honored this since 2015 across 900+ ADUs, and the paperwork is part of your contract, not a handshake.
Valid through December 31, 2026. Mention this offer when you call (657) 366-5740.
Documented Photo Record Included on Every Visit - No Charge
Most Anaheim contractors give you a verbal summary or a few phone snapshots. We deliver a dated, documented photo record showing what we found and what we did - foundation conditions, existing electrical panels, sewer lateral locations, the actual condition of your garage slab before conversion. You get evidence, not a feeling. This is standard on every Ellery project, never billed as an add-on.

Written Price Before Any Work Starts - Haven Standard Clause 1
We don’t do “call for a quote.” Every Anaheim ADU project, from a 400-square-foot Junior ADU in the Anaheim Colony Historic District to a full detached unit near the Platinum Triangle, receives a written, line-item price before any work begins. If the scope doesn’t change, the price doesn’t change. No door-side upsells, no “we found an issue” mid-project surprises.

Live Person Answers Calls 24/7 - No Voicemail Queue
ADU questions don’t keep business hours. Whether you’re reviewing plans at 10 PM or your contractor just ghosted you on a Saturday morning, a live person answers at (657) 366-5740. No callback promise that evaporates, no “leave a message and we’ll get back to you Tuesday.” This is how we’ve operated since 2015, and it’s not changing.

One-Contract Design-Build - Designer and Builder Under One Written Agreement
In Anaheim’s ADU market, the classic failure mode is the architect blaming the builder and the builder blaming the architect while you’re stuck with a half-permitted project. Our design-build model puts ADU Design & Permitting, construction, and Site Prep & Utilities under a single contract with a single written price. One point of accountability, one warranty, one phone number.
Valid through December 31, 2026. Mention this offer when you call (657) 366-5740.
How to Redeem

Step 1: Call (657) 366-5740 and mention the offer you want to use. A live person will pick up, day or night.
Step 2: Book your site visit or estimate. For most Anaheim properties, we can walk the lot, assess access for a detached ADU or measure your existing garage for conversion, and identify utility tie-in points in a single visit.
Step 3: Present any relevant paperwork at the time of service - your existing estimate for the Second Opinion, your property survey, or prior permit correspondence with the city of Anaheim. We’ll apply the offer and deliver your written quote under Haven Standard Clause 1.
What These Offers Actually Cover in Anaheim
Anaheim’s ADU market has specific constraints that make generic “specials” misleading. The city allows detached ADUs up to 1,000 square feet on most single-family lots, but setback requirements vary by zoning - R-1, R-1-H, and the specific overlay districts near Disneyland Resort or the Anaheim Canyon area each carry different rules. Garage conversions in older Anaheim neighborhoods like Anaheim Colony or West Anaheim often encounter unpermitted prior work, clay soil expansion, or sewer laterals that don’t meet current code. Our offers are structured around these realities, not around a fantasy project that ignores permitting, soils, or utility capacity.
We’ve specified and coordinated prefab and modular systems from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie within the same single-contract framework. Whether you’re comparing a site-built garage conversion to a Cover unit or trying to understand how a Boxabl module interfaces with Anaheim’s foundation requirements, the written price and photo documentation apply identically. The Haven Standard doesn’t care what system you choose; it cares that you know what you’re paying before you commit.
Our 900+ projects since 2015 include Anaheim properties where the owner-builder exemption seemed appealing until the homeowner realized they’d need to pull their own permits, hire their own inspectors, and assume liability for code compliance. We’re not here to talk you out of that path if you’re genuinely prepared for it. We are here to give you a written comparison so the decision is informed, not improvised.

Call (657) 366-5740 to confirm which offer fits your specific project.
The Haven Standard protections - written price, photo record, Done Right Promise - are already bundled into every project. The Free Second Opinion is a standalone service for homeowners who already have another contractor’s estimate in hand. You don’t “stack” these; you receive them as standard operating procedure.
Call (657) 366-5740 and we’ll clarify what applies to your situation.
We serve 19 cities across Orange County and adjacent areas. Anaheim remains our primary market, and these offers are explicitly structured for Anaheim’s permit timelines, zoning codes, and utility providers (Anaheim Public Utilities for electric, Anaheim Public Works for sewer connection standards). If your property is just outside city limits, call (657) 366-5740 and we’ll confirm applicability.
Call (657) 366-5740 with your address and we’ll verify coverage.
Because we’d have to inflate the base price to make the discount look meaningful, and that’s the opposite of Haven Standard Clause 1. Our value is transparency: you see the actual cost of design, permitting, materials, labor, and project management before you sign. A “20% off” coupon on a mystery price is worse than a written fair price with no discount.
Call (657) 366-5740 for your written estimate - no coupon required.
Every client receives: a written scope of work with line-item pricing, a permit set approved by the city of Anaheim, a dated photo record from every site visit, and the 365-Day Done Right Promise in writing. These are deliverables, not marketing language. You can show them to your lender, your insurance agent, or your real estate attorney.
