Blanco Home Additions & ADU: The Fresno Owner’s Guide
Blanco home additions and ADU construction in Fresno typically run $45,000 to $130,000 for an addition and $90,000 to $220,000 for a freestanding ADU, depending on square footage, site conditions, and finish level. We assess the structural tie-in, foundation approach, and utility rough-in before we put a single number in front of you. Most Fresno homeowners discover they need this work when their family outgrows the floor plan but the lot still has room, or when a failed DIY garage conversion reveals just how unforgiving Fresno’s hardpan soil can be under a slab that wasn’t engineered for living space.
This page is for the owner who already knows they need more square footage and wants straight answers on compatibility, cost, and what the process actually looks like from permit to final inspection. Bradford Remodeling Co Fresno is an independent contractor and is not affiliated with the Blanco brand. What we bring to a Blanco-named project is the same thing we bring to every job in Fresno: a written price, a defined scope, and a one-year guarantee in your hand when the work is done.
Which Blanco Projects This Applies To
“Blanco” is not a line of construction materials we stock on a shelf the way a Blanco sink or faucet gets pulled from inventory. In Fresno, Blanco appears most often as the name on the existing home’s kitchen or bath fixtures when a homeowner starts planning an addition or ADU around those same finishes. That matters because the addition has to integrate with the existing home’s plumbing rough-ins, drain locations, and fixture spacing, not just match the color of the countertops.
When we scope a home addition or ADU for a Fresno home with Blanco fixtures, the compatibility question is not about the brand name. It’s about whether the existing drain and supply lines, vent stack, and water-heater capacity can carry the added load. Blanco kitchen faucets and sinks run standard US rough-in dimensions, so a new ADU kitchen can be plumbed to accept Blanco fixtures without custom work. The gotcha is flow rate: some Blanco pull-down faucets run 1.8 GPM, which works on a standard supply line, but a second kitchen or wet bar may require upsizing the supply branch if the existing line is 1/2-inch and already feeding two bathrooms. We check that before the walls close.
The aftermarket conversation for Blanco is simple: we don’t install off-brand Blanco knockoffs. If you want Blanco fixtures in the new space, we order genuine Blanco through our supplier network and give you the model number on the written estimate. If you want to save money, we’ll spec Kohler or Moen equivalents, tell you exactly what changes, and put that in writing too. The estimate says what we build, and we build what the estimate says.
Styles & brands we work with
Signs Your Blanco Home Additions & ADU Project Is Failing
- Foundation settling at the tie-in joint. Fresno’s expansive clay soil moves with moisture, and an addition slab poured without proper compaction or a proper tie-in key will show a hairline crack at the joint within two seasons. We see it most often on older Fresno additions in the Tower District where the original home was pier-and-beam and the addition got a slab.
- Utility rough-ins that don’t match the existing home. If the previous contractor tied the new drain line with the wrong slope or used mismatched pipe, you’ll get slow drains in the addition or gurgling from the Blanco sink when the washing machine discharges. That’s a rough-in error, not a fixture problem.
- Roof tie-in leaks at the valley. A poorly flashed addition roof leaks where it meets the main house, and in Fresno’s winter rain months that shows up as staining on the ceiling of the new room. The fix is re-flashing and often partial reroofing, not caulk.
- No permit on file. If the addition or ADU was built without a Fresno building permit, you’ll discover it when you try to sell, refinance, or insure the property. That firesale addition costs more to legalize than it saved to build.
- Drywall cracking at the new wall corners. When an addition settles independently from the original structure because the contractor skipped the proper seismic tie, the new interior corners crack within the first year. The crack runs diagonal from the corner, not along the tape line.

AfterReplacement Cost & What’s Included
A home addition in Fresno runs $45,000 to $130,000 installed. That range covers everything from a modest 300-square-foot bedroom bump-out with a stucco exterior match to a 700-square-foot great room addition with a bathroom, kitchenette, and custom ceiling details. The number moves based on three things: foundation type (slab on grade is cheapest, raised floor with crawl space pushes the price up), utility distance (running a new drain line 80 feet to the sewer lateral costs real money), and finish level (paint-grade trim versus custom cabinetry).
An ADU runs $90,000 to $220,000 in Fresno. Detached units cost more than garage conversions because they need their own foundation, roof, and utility trenching. A garage conversion typically comes in between $30,000 and $80,000, depending on whether the existing slab passes inspection and how much electrical and plumbing work the space needs.
Every Bradford Remodeling Co Fresno quote includes the written price for permits, demolition, structural work, plumbing and electrical rough-in, drywall, paint, and the documented finishes listed in the estimate. No number moves at the door. When the job closes, you get a signed written guarantee: if the work fails within 365 days, we come back and make it right at no charge. That’s the 365-Day Done Right Promise, and it’s been the standard since we started operating under The Garrison Standard.
DIY or Call Us?
You can do the planning homework yourself in Fresno. Check your lot’s zoning and setback requirements through the City of Fresno Planning Division. Walk your property line and mark where the addition or ADU would sit relative to existing power lines and the sewer lateral. Measure the interior space you want to add and compare it against the $150 to $400 per square foot typical range so you know if your budget and your plan are in the same room.
What you should not do yourself is any structural work: foundation excavation, framing a tie-in to the existing roofline, running a new gas line, or moving a load-bearing wall. Those failures don’t show up as a crooked tile line. They show up as a sagging ridge beam, a propane smell, or a wall that moves when the wind blows. Curtis Lane has spent over two decades in Central California doing that work right, and his crew knows what the Fresno building inspector looks for before drywall goes up. If you’re pricing this project, call (559) 785-2712. The estimate is free, and it tells you exactly what we’ll build and what it costs.
FAQs
A typical Fresno home addition takes 3 to 6 months from permit submittal to final inspection, and a detached ADU runs 4 to 9 months depending on utility trenching and foundation work. The single biggest schedule variable in Fresno is the permit review queue, which is why we pull permits the same week the contract is signed, not the week we’re done with framing. Call (559) 785-2712 and Curtis can give you a realistic timeline for your specific project after one site walk.
We repair additions and ADUs when the structure is sound and the problem is localized: a failing roof tie-in, a settling corner, an undersized beam, a plumbing rough-in that never drained right. What we won’t do is patch over a foundation that was never engineered for living space in Fresno’s soil, or drywall over a permit problem and call it finished. Bring us the issue and we’ll tell you straight whether it’s a repair or a rebuild. Call (559) 785-2712 for that assessment.
Yes, we pull every permit the job requires, in our name, before work starts. That includes the building permit, electrical, plumbing, mechanical, and the encroachment permit if we’re trenching to the street. The price of permits is a line item on the written estimate, not a surprise at the end. If an ADU or addition was built previously without a permit, we can help you legalize it, but that process has its own cost and schedule in Fresno.
We order and manage all materials through our supplier accounts, which include documented brands like KraftMaid, Cambria, Silestone, Kohler, Moen, GAF, James Hardie, and Therma-Tru. If the project calls for Blanco fixtures to match the existing home, we order genuine Blanco through our supply network and the model number goes on the written estimate. You never chase a delivery or a backorder. That’s our job.
Most Fresno home additions land between $150 and $400 per square foot depending on foundation work, utility runs, and finish level, which puts the total project range at $45,000 to $130,000. A simple bump-out with stucco exterior and paint-grade trim sits at the low end; a kitchen or bathroom addition that requires new drain lines and high-end porcelain sits at the top. Call (559) 785-2712 and we’ll price yours from a site visit, not a formula.
