Free Second Opinion on Any Written ADU Estimate
Already have a quote for a garage conversion, detached ADU, or JADU in Rialto? Bring us that written estimate and we’ll review every line item against current San Bernardino County permit fees, typical Rialto foundation conditions, and the actual scope shown on the drawings. We’ll flag what’s missing, what’s inflated, and what the city will likely redline at plan check. No obligation to hire us afterward.
Valid through December 31, 2026. Mention this offer when you call (951) 476-1467.
365-Day Done Right Promise - Written at Contract, Not at Close-Out
Every Rialto ADU project we take includes this in writing before the first shovel hits dirt: if the finished unit isn’t built to the permitted drawings, we make it right. That’s not a handshake. It’s Haven Standard Clause 7, signed by Nadia Ellery, and it stays in force a full year past final inspection. Most competitors bury this language or limit it to 30 days.
Valid through December 31, 2026. Mention this offer when you call (951) 476-1467.
Documented Photo Record Included on Every Site Visit
We don’t send summary emails about how your Rialto ADU build “felt” that day. Our crews document what they found and what they did with dated, geotagged photos uploaded to your project folder. Rebar placement before the pour, existing slab thickness at your garage conversion, trench depth for sewer lateral work - you see it, not hear about it. Included at no extra charge on every visit, not just the final walkthrough.

Written Price Before Any Work Starts - Haven Standard Clause 1
This isn’t a discount. It’s the foundation of how we operate. Every Rialto homeowner receives a line-item written quote before any design hours, permit submissions, or construction begins. The words “call for a quote” do not appear on our site or in our office because they don’t appear in our process. Your price is fixed at signing under Clause 5 (No Surprises) - no door-side upsells, no scope creep when the drywall’s open.

Live Person Answers 24/7 - No Voicemail Queue
Call (951) 476-1467 at 10 PM on a Sunday with a question about your Rialto garage conversion permit status, and a live person picks up. Not a callback promise that doesn’t materialize. Not an overseas answering service reading a script. This is how we handle the anxiety that comes with a five-figure project - by being reachable when you’re actually worried about it.

One-Contract Design-Build - No Designer-Builder Finger-Pointing
Book your Rialto ADU under our single contract covering design, permitting, and construction. When the as-built framing doesn’t match the structural drawings, we don’t point at the architect. When the city requests a soils report for your Muscoy-adjacent lot with questionable fill, we handle the revision in-house. One written price, one point of accountability, one phone number: (951) 476-1467.

Step 1: Call and mention the offer. Dial (951) 476-1467, tell us which special caught your attention, and we’ll note it on your project file before we schedule.
Step 2: Book your site visit or estimate. We’ll walk your Rialto property, assess existing conditions - slab depth, setback measurements, utility access - and start building your line-item quote.
Step 3: Present at signing. Your offer language gets attached to your written contract under the applicable Haven Standard clause. No surprises, no “I forgot to mention it” at the door.
Before
AfterWhat These Offers Actually Cover in Rialto
Rialto sits on a mix of alluvial fan deposits and compacted fill that varies block by block. We’ve designed and permitted ADUs here since 2015, and we’ve learned that “standard” foundation details from a Santa Monica architect often fail Rialto plan check. Our specials reflect that local knowledge. The free second opinion catches out-of-town contractors who don’t know San Bernardino County’s fire separation requirements for garage conversions. The photo record documents your existing 4-inch slab versus the 6-inch the city may require for a detached unit. The written price accounts for actual Rialto permit fees, not Los Angeles estimates with a shrug.
We’re not discounting our work because we cut corners. We’re making our standard process visible so you can compare it honestly against competitors who bury their terms. Nadia Ellery has overseen 900+ ADUs from drawings through final inspection, and every one started with the same document: a written price, a clear scope, and a signature.
Frequently Asked Questions
Yes. The Haven Standard clauses stack. Your project gets the written price guarantee, the photo record, the Done Right Promise, and the single-contract accountability all together. Call (951) 476-1467 and we’ll walk through how each clause applies to your specific garage conversion or detached ADU.
No. Bring us any written estimate from any contractor for any ADU service in Rialto. We’ll review it. If our assessment is that the quote is fair and complete, we’ll tell you that too. The offer exists because too many Rialto homeowners sign contracts with missing permit fees or undefined utility connection scopes.
Any project contracted before December 31, 2026, locks in these terms for its full duration. The “valid through” date governs when you sign, not when we pour the foundation. Rialto’s permit timeline typically runs 4-6 months for a garage conversion and 8-12 months for a detached ADU, so most projects cross a calendar boundary. Your contract language stays fixed.
Yes. We specify and coordinate Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie systems under the same single contract and the same written warranty. If the module placement doesn’t match the approved site plan, or if the factory connection details differ from what Rialto building inspection signed off on, we make it right. The promise doesn’t distinguish between stick-built and prefab - the permitted drawings govern either way.
