ADU Specials in Fresno, CA
If you’re weighing the cost of an ADU, a home addition, or a room addition in Fresno, call Benson ADU Fresno at (559) 206-2363 before you commit to anyone. We run straightforward seasonal offers because planning a build is already complicated enough without wondering whether you left money on the table. What we won’t do is dress up a vague discount and call it a deal. Every offer below is tied to the way we already work: a written price before any work starts, brand-name materials you can research yourself, and a 365-day guarantee that’s actually on paper.
Current Offers

Free Written Price Quote for Any ADU, Home Addition, or Room Addition
Every project gets a written line-item price before any work starts. That’s not a limited-time gimmick at Benson ADU Fresno, but for a limited window we’re making the site visit that produces that quote completely free, with no obligation and no follow-up pressure. You’ll see exactly what you’re paying for: setbacks, permitting line items, foundation scope, finishes, and the ADU brand you chose.
Valid through March 31, 2027. Mention this offer when you call (559) 206-2363.
365-Day Done Right Promise: Free Second Visit If Any Covered Repair Fails
Our standard guarantee already runs a full year, in writing, stamped on every project. If something we built or installed isn’t right within 365 days, we come back and make it right, and if a covered repair fails, that second visit is free. This offer is our way of reminding Fresno homeowners that a written guarantee should be the rule, not the upsell.
Valid through March 31, 2027. Mention this offer when you call (559) 206-2363.
Prefab ADU Brand Comparison Session, Free
If you’re torn between an Abodu unit, a Dvele build, a Boxabl, Cover, Mighty Buildings, Plant Prefab, or a Tuff Shed studio, we’ll walk you through the trade-offs in plain English. Prefab panel means the walls arrive pre-built in sections; site-built means we frame everything on your lot. You’ll get honest pros, cons, and pricing by brand, not a sales pitch for whichever one we’d rather build.
Valid through March 31, 2027. Mention this offer when you call (559) 206-2363.
James Hardie Cladding Upgrade Consultation, Free
Asked for cladding that survives a Fresno summer without fading or warping by year three and James Hardie fiber cement is the answer we keep giving. If you’re planning an ADU or addition, we’ll review your cladding options with you at no cost, including the real difference between HardiePlank lap siding and HardiePanel vertical siding, which matters when you’re matching the main house.
Valid through March 31, 2027. Mention this offer when you call (559) 206-2363.
Senior and Military Courtesy: $0 Site Consultation
Older homeowners in Fresno and active or retired military families get the same written-price process everyone else does, but we waive the site consultation fee entirely. No proof of anything beyond a quick mention when you call. This isn’t a discount on construction quality or materials, it’s a courtesy on the planning stage where we’d rather earn the work honestly.
Valid through March 31, 2027. Mention this offer when you call (559) 206-2363.
Start-to-Permit Planning Package, Free With Signed Build Agreement
Fresno homeowners who sign a build agreement during this window get our full planning package included at no charge: site measurements, setback verification (that’s the minimum distance your ADU must sit from property lines), a draft floor plan, and permit application preparation. We’ll still pull permits properly and won’t touch a shovel until they’re approved.
Valid through March 31, 2027. Mention this offer when you call (559) 206-2363.
How to Redeem
Three steps and you’re done. First, call (559) 206-2363 and tell whichever live person answers which offer you’re calling about. Second, book your site visit, we’ll confirm a written arrival window and a background-checked, uniformed technician will show up as scheduled. Third, present the offer at the time of service, and if you’re redeeming one, bring it up again before you sign anything so we can put it on the written price.
Why These Offers Exist
Troy Eastman, Owner at Benson ADU Fresno, will tell you the same thing he tells every homeowner on a first call: a good ADU deal is one where you know the price before you commit, the warranty is in writing, and the person on your property is who they said they were. Troy has been around long enough to know that Fresno’s summer heat punishes cheap cladding and that a vague verbal estimate always, always grows. The offers above exist because the work itself is the same work we’d do at full price, done right the first time, with a 365-day promise behind it. That’s the deal worth taking.
Frequently Asked Questions About ADU Pricing in Fresno
Most ADU builds in Fresno land between $180,000 and $320,000 depending on size, site work, finishes, and whether you choose a prefab unit like a Boxabl or Cover versus a site-built structure. A detached one-bedroom ADU with a kitchenette and bath tends to start around $190,000; a larger two-bedroom unit with upgraded cladding runs higher. These are ballpark figures, not quotes. Call (559) 206-2363 and we’ll give you a written price for your exact lot and scope.
Not if you work with us. Every Benson ADU Fresno project gets a written price before any work starts, and that price is what you pay unless you choose to add scope yourself. Written means on paper, not a verbal estimate that shifts later. That’s the whole point of how Troy Eastman runs this company.
Yes. We handle permit applications and won’t begin construction until permits are approved. ADUs in Fresno must meet setback requirements, which is the minimum distance between your new structure and your property lines, and that number varies by parcel. We measure, verify, and submit the paperwork correctly the first time.
Prefab panel projects from brands like Abodu and Mighty Buildings can be weathertight in weeks rather than months, while site-built additions take longer because framing, electrical, and finishing happen incrementally on your lot. Your written quote will include a realistic schedule for your specific build, and we don’t pad timelines to look good later.
Sometimes, but not always. A prefab ADU from Dvele or Plant Prefab can save money on framing labor, but site work, foundation, utility connections, and permits cost the same either way. A Tuff Shed studio conversion starts at a lower price point but includes fewer finished systems than a fully permitted ADU. We’ll show you the real numbers by brand before you decide.
