ADU Specials in Riverside, CA
If you’re planning a detached ADU, room addition, or home addition in Riverside, call Sutton ADU Riverside at (831) 217-6083 before you commit to any builder. We run a small number of standing offers each season, and the honest framing is this: the most valuable thing we offer is the written price before any work starts, not a flashy discount. That written price is the real special. But yes, we also have a few courtesies worth knowing about, and they’re all listed below.
Current Offers
Free Written Estimate and Site Visit
Every Riverside homeowner receives a free, no-obligation site visit and a written line-item price before any work begins. This is the Threshold Standard, and it applies to every project from a 400-square-foot studio ADU to a full room addition. No range, no ballpark, no verbal assurance. You get the number on paper before you sign anything.
Valid through March 31, 2027. Mention this offer when you call (831) 217-6083.
Free Second Visit on Any Failed Element Within One Year
The 365-Day Done Right Promise already covers defects in workmanship for one full calendar year from project completion. If any element of the build fails in that window, we return for a free second visit, no haggling and no fee. This is a named, written guarantee stamped on every project, not a verbal assurance.
Valid through March 31, 2027. Mention this offer when you call (831) 217-6083.
Senior and Military Courtesy
Riverside homeowners 65 and older, active-duty military, and veterans qualify for a courtesy applied to project management fees on any ADU, room addition, or home addition. Bring it up when you call, and Miles will make sure it’s reflected in your written estimate. It’s a small thank-you that doesn’t get buried in line items.
Valid through March 31, 2027. Mention this offer when you call (831) 217-6083.
First-Time Customer ADU Planning Session
If you haven’t worked with Sutton ADU Riverside before, your first planning session is free and unhurried. We’ll review your lot, setbacks (the required gap between your new structure and the property line), and which prefab line fits: Abodu, Cover, Dvele, Mighty Buildings, Boxabl, or Plant Prefab. You’ll leave with a clear sense of what’s buildable and what it will cost.
Valid through March 31, 2027. Mention this offer when you call (831) 217-6083.
Tuff Shed Conversion Assessment
Already have a Tuff Shed on your Riverside lot and wondering if it can become a permitted ADU? We’ll assess the structure and tell you honestly whether a conversion pencils out against a new build. If it doesn’t, we’ll say so. The assessment is free, and the written price for conversion work follows the same rule as everything else: it’s on paper before you commit.
Valid through March 31, 2027. Mention this offer when you call (831) 217-6083.
James Hardie Cladding Upgrade Review
Considering a room addition and want the exterior to match your existing Hardie cladding system? We’ll review the match, material availability, and installation cost at no charge and fold it into your written estimate. This offer applies to additions in Riverside, and it’s worth asking about if you’re particular about curb continuity.
Valid through March 31, 2027. Mention this offer when you call (831) 217-6083.
How to Redeem
Redeeming any of these offers takes three steps and no special codes. Call (831) 217-6083 and mention the offer by name. A live person answers every call, every day, and will note it on your file. Then we schedule the site visit or planning session at a time that works for you. When your technician arrives, confirm the offer at the door. Every field person is background-checked, identity-verified, uniformed, and photo-badged, and their name and photo are sent to you before arrival, so you’ll know exactly who you’re expecting.
Why We Run Offers This Way
Sutton ADU Riverside started in 2006 as part of the Threshold Group family of home-service companies, and we’ve always operated under the same Threshold Verified standards. The written price comes before work starts, on every project, no exceptions. The 365-Day Done Right Promise covers workmanship for a full year. Those two things are worth more than any percentage-off coupon, because they protect you from the surprise invoices and silent scope creep that plague this industry. The offers above are courtesies for specific Riverside homeowners, not gimmicks. If you’re weighing a detached ADU in Wood Streets, a room addition in Canyon Crest, or a garage conversion near UC Riverside, call us and ask for the written price. That’s the number that matters.
What These Offers Don’t Cover
Some things should be said plainly. ADU construction in Riverside involves permits, site work, and utilities, and those costs are not discounted or waived by any offer on this page. The city’s ADU permit fees, school district fees, and utility connection charges are set by agencies, not by us. What we control is our workmanship, our responsiveness, and our willingness to give you an honest written number before you commit. Those are the guarantees, and they’re not seasonal.
Call for a Written Price
The most useful next step is a free site visit and a written estimate. Call (831) 217-6083, mention any offer that applies to you, and we’ll schedule the visit. If you have questions about ADU size limits, setback rules, or which prefab line fits your lot and budget, ask. We’ll answer plainly, including when a number is higher than it needs to be.
