Straight answers to the questions Fresno homeowners ask us most about accessory dwelling units. If you don't see your question here, call (559) 785-0627 and we'll talk it through.
Pricing & Cost FAQs
A detached ADU in Fresno typically runs between $180,000 and $350,000, while garage conversions usually land between $90,000 and $160,000. Your final number depends on square footage, site prep, utility work, and finish level. Fresno's flat lots help keep foundation costs predictable, but older neighborhoods like the Tower District often have outdated electrical panels that add to the budget. We put every price in writing before any work starts, so you know your exact number before signing anything. Call (559) 785-0627 for a free written estimate on your specific property.
A garage conversion is almost always the least expensive ADU in Fresno, because the structure, foundation, and roof already exist. You're paying for insulation, drywall, electrical, plumbing, and finishes rather than starting from bare dirt. In neighborhoods like Sunnyside and McLane, attached garage conversions save even more by sharing walls and utility runs with the main house. Junction boxes and panel upgrades are the most common surprise cost in older Fresno homes. We'll walk your property and give you a written price before any work begins.
No. Every Sutton ADU Fresno project gets a written, line-item price before any work starts, and we don't issue change orders unless you request a change yourself. Fresno's soil is generally stable, which reduces the surprise foundation costs you'd see in other California markets. What we quote is what you pay. If something unexpected does appear during construction, we sit down with you first, explain the issue in plain language, and get your written approval before spending another dollar. Call (559) 785-0627 if you want to see how we structure our estimates.
Fresno's permit fees are published by the city, and we include them as a line item in your written estimate rather than burying them in a lump sum. The city charges based on project valuation, and school impact fees and sewer connection fees often apply. In newer developments north of Herndon, utility connection fees can be lower because stub-outs already exist. In older areas like the Tower District, sewer lateral replacements sometimes add cost. We don't mark up permit fees. What the city charges is what we pass through, itemized on your estimate.
ADU permit fees in Fresno typically fall between $4,000 and $9,000 depending on project size and valuation, not including school impact fees. The city's published fee schedule covers plan check, building inspection, and utility reviews. We pull every permit for your project and handle the corrections process ourselves, so you don't chase paperwork. The exact number depends on whether you're doing a garage conversion, an attached addition, or a detached new build. Call (559) 785-0627 and we'll give you a real-world estimate based on the scope.
Service & Process FAQs
The process runs: site visit and feasibility check, design and engineering, permit submission, construction, and final inspection. In Fresno, you'll also need to confirm your lot's zoning allows an ADU (most single-family zones do under state law) and check for any HOA restrictions in neighborhoods like Woodward Lake. Once permits are approved, a detached ADU typically takes 6 to 12 months from groundbreaking to final inspection; garage conversions run faster at 3 to 6 months. We handle every step, including the permit submittal to the City of Fresno.
A detached ADU in Fresno generally takes 6 to 12 months once construction begins, while a garage conversion usually finishes in 3 to 6 months. The wider range on new builds reflects variables like utility trenching, weather delays in December and January, and the city's inspection scheduling. Plan check and permit approval happen before construction and typically add 6 to 12 weeks. During your free estimate, we'll give you a clear timeline based on your lot, your scope, and the current permit queue. Call (559) 785-0627 to get started.
Most single-family residential lots in Fresno qualify for at least one ADU under California state law, but setbacks, lot size, and utility access vary by neighborhood. A narrow lot in the Tower District has different constraints than a half-acre property in Clovis or Sanger. We walk your property during the free estimate, check the parcel against city requirements, and tell you honestly whether an attached, detached, or conversion ADU fits best. If your lot won't support your preferred plan, we'll say so plainly rather than forcing a bad fit.
Yes. We pull every building permit for your ADU project and manage the entire plan check process with the City of Fresno. That includes submitting the plans, responding to plan checker comments, scheduling inspections, and walking the final with the inspector. You don't file anything yourself. Fresno's plan check can be detail-heavy on items like fire sprinkler exemptions and energy compliance, and we know what the reviewers look for. Call (559) 785-0627 and we'll explain the permit path for your specific project.
Yes, garage conversions are one of the most common ADU projects we do across Fresno. A conversion works best when the existing slab and framing are sound, which is why we inspect before quoting. In central Fresno neighborhoods like Huntington Boulevard, detached garages from the 1940s and 1950s sometimes need structural upgrades, while newer garages in places like Harlan Ranch and Woodward Park convert cleanly. Your converted garage becomes a fully independent living space with its own kitchen, bath, and private entrance. We provide a written line-item price before any work starts.
We build both detached ADUs and garage conversions in Fresno, and we'll tell you which makes more sense for your lot and budget. A detached ADU gives you a brand-new structure with your choice of layout and finishes, while a conversion uses what's already there. Lots with generous rear yards in places like Fig Garden and Old Fig often suit a detached unit, while smaller parcels in the Tower District may work better as a conversion or attached addition. During the free estimate, we'll show you the cost and timeline for both options.
Brands & Parts FAQs
We're familiar with prefab ADU manufacturers including Abodu, Cover, and Dvele, and we can discuss whether a prefab approach fits your Fresno property. Prefab units can shorten on-site construction time, but site work, foundation, and utility connections still happen locally, and those costs don't disappear. Some Fresno lots have access constraints that make a factory-built module hard to deliver, which is something we check early. If you're weighing prefab against stick-built, we'll walk you through the real comparison for your specific site. Call (559) 785-0627 to talk it through.
Yes, James Hardie fiber cement siding is one of the exterior options we offer on ADU projects in Fresno. It holds up well through the Central Valley's hot, dry summers and the rainy winter months without warping or fading the way some cheaper sidings do. Many Fresno homeowners choose it because it stands up to the valley's temperature swings and needs less repainting over time. It's not the only option we offer, but it's one we're comfortable recommending. Your written estimate will line out the exterior finish choices and their costs.
A turnkey ADU means you hand us the project and we hand you back a finished, move-in-ready living space. That includes design, engineering, permits, site work, foundation, framing, electrical, plumbing, HVAC, drywall, paint, flooring, cabinetry, fixtures, and final inspection. In Fresno, we also handle the utility connections with the city, which can trip up DIY builds. The only things you buy yourself are furniture and personal items. Our written estimate spells out every line item so there's no ambiguity about who's responsible for what.
Licensing & Insurance FAQs
Yes. Every pro working under the Sutton ADU Fresno name is required to hold the license and insurance the state requires for their trade. The Threshold Standard means each technician is background-checked and identity-verified before they ever step onto your property. You'll get the name and photo of your technician before the visit, and they'll show a photo ID badge at your door, every time. We don't ask you to take our word for it; we prove who's coming before they arrive. Call (559) 785-0627 and we'll walk you through it.
The Threshold Standard is the set of requirements every Sutton ADU location agrees to meet on every job. It means every technician is background-checked and identity-verified; you receive the tech's name and photo before the visit; the tech shows a photo ID badge at the door; they arrive in a clean, marked uniform; and your price is in writing before any work starts. The standard exists for homeowners who don't want to open their door to a stranger. If anyone arrives who you were not told to expect, that visit is on us and we make it right.
Because we tell you exactly who is coming to your home before they arrive, and we prove it at the door. You get the name and photo of your technician ahead of time, and they show a photo ID badge when they show up. Every price is written down before any work begins, so there's no verbal estimate that drifts upward. Sutton ADU Builders is the ADU company of the Threshold Group family, and this Fresno location is independently owned and operated by people who live and work here. That's a different experience than hiring an unknown crew off a listing site.
Emergency & Response FAQs
We're not a 24/7 emergency service, and we won't pretend to be. Our hours are Monday through Friday from 7:00 AM to 7:00 PM and Sunday from 7:00 AM to 7:00 PM, closed Saturday. If you have an urgent issue with an existing ADU, such as water intrusion or a failed electrical circuit, call us during those hours and we'll get a qualified person out to assess the situation. For active gas leaks or downed power lines, contact PG&E or 911 immediately. For everything else, call (559) 785-0627.
We schedule free property walkthroughs during our normal business hours, Monday through Friday from 7:00 AM to 7:00 PM and Sunday from 7:00 AM to 7:00 PM. When you call (559) 785-0627, a live coordinator will get you on the schedule at a time that works for you. We cover Fresno and the surrounding communities including Clovis, Madera, Reedley, Fowler, Visalia, Firebaugh, Tulare, Sanger, Selma, Kerman, and Kingsburg. The walkthrough takes about an hour and gives us what we need to build your written estimate.
First, protect what's inside: move valuables away from the water and place a bucket or tarp to catch the drip. Then call us during business hours at (559) 785-0627 and we'll assess the situation. Fresno's heaviest rains typically hit between December and February, and water intrusion during those months needs prompt attention to prevent drywall and insulation damage. We'll send a qualified pro to identify the source of the leak and give you a written price for the repair before any work starts. Don't climb onto a wet roof yourself.
Warranty & Guarantees FAQs
Every ADU project we complete is covered by Threshold Verified, which is the guarantee that the people who worked on your home were background-checked, identity-verified, photo-badged, and sent to you by name and photo before the visit. If anyone arrives who you were not told to expect, that visit is on us and we make it right. Workmanship details are spelled out in your written contract before any work starts, so there's no guessing later about what's covered. Call (559) 785-0627 and we'll walk you through the paperwork line by line.
Yes, we stand behind our work, and that's written into your contract before construction begins. Sutton ADU Fresno operates under the Threshold Verified promise, which means you knew who was coming to your property, you saw their ID at the door, and your price was in writing before a single day of work happened. If something comes up after your project is complete, call us at (559) 785-0627 and we'll send a qualified person out to look at it. We want your ADU to work for you long after the final inspection.
It's a real promise with specific terms, not a slogan. The Threshold Standard requires every technician to be background-checked and identity-verified before they step onto your property. You receive their name and photo before the visit, they show a photo ID badge at the door, they arrive in a clean, marked uniform, and your price is in writing before any work starts. If someone shows up who you weren't told to expect, that visit is on us. Call (559) 785-0627 and we'll show you exactly what it covers on paper.
Call us. We'd rather hear about a problem early than find out you've been stewing on it for six months. The Threshold Standard means we put your price in writing before any work starts, so there's a documented baseline for what was agreed. If something doesn't look right, we'll send a qualified pro out to assess it and give you a straight answer, not a runaround. Sutton ADU Fresno is an independently owned local business, and our reputation in Fresno depends on making things right. Call (559) 785-0627.
