ADU Specials in Riverside, CA
If you’re pricing an ADU or home addition in Riverside, call Benson ADU Riverside at (831) 231-0809 before you commit to anything. We run seasonal offers for one reason: a well-timed project beats a rushed one, and we’d rather see that savings go into better finishes than into hurry. Every special below comes with the same written price promise as our full-price work. No bait. No fine-print gotchas. Just honest numbers on paper before you spend a dime.
Current Offers

Free Written Estimate + Site Visit for Any ADU or Addition
We’ll walk your Riverside property, measure the setback, check utility access, and hand you a written price before we leave. This covers everything from a detached ADU in the backyard to a garage conversion or a room addition off the kitchen. No verbal ballparks that drift later, just a line-item number you can hold us to.
Valid through March 31, 2027. Mention this offer when you call (831) 231-0809.
First-Time Customer Courtesy: Free Design Consultation with Troy
Sit down with Troy Eastman, our Owner and Project Lead, and get straight answers about what your ADU will actually cost in Riverside’s current market. He’ll walk you through prefab options from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, and Tuff Shed, plus site-built approaches with James Hardie cladding. You’ll leave knowing your real budget, not a sales pitch.
Valid through March 31, 2027. Mention this offer when you call (831) 231-0809.
Seasonal Tune-Up: Free Permit-Ready Drawing Review
Already have plans from another contractor or a prefab company? Bring them in and we’ll review them against Riverside’s current ADU requirements before you pay filing fees. We’ll flag anything that could stall your permit or add cost later. This is a second set of expert eyes, free of charge, for a limited window each season.
Valid through March 31, 2027. Mention this offer when you call (831) 231-0809.
Senior & Military Courtesy: Complimentary Site Feasibility Walk
If you’re a senior or active/retired military in Riverside, we’ll visit your property and assess whether an ADU, JADU, or room addition fits your lot at no cost. You’ll get plain-language answers about setbacks, utility runs, and what your specific neighborhood typically allows. Just mention it when you call, and we’ll set it up.

The 365-Day Done Right Promise: Extended Care Check-In
Every Benson ADU Riverside project already carries a written guarantee for a full year after completion, but through this offer we’ll schedule a proactive check-in visit before your year is up. We’ll inspect the work, answer questions, and address anything that isn’t right, at no charge. That’s not a coupon so much as how we’ve always done business, written down where you can see it.
Valid through March 31, 2027. Mention this offer when you call (831) 231-0809.
Free Second Visit on Any Covered Repair
If a repair we performed fails during the covered period, the second visit is free. Period. It’s part of our written guarantee on every project, and it’s in the paperwork you sign before work starts. Riverside homeowners tell us they didn’t believe it until they needed it, and then we showed up and made it right.
Valid through March 31, 2027. Mention this offer when you call (831) 231-0809.
