Adding a room or a full second story in Dinuba means dealing with older framing, outdated wiring, and flat-lot drainage before the first wall goes up. That’s the honest truth, and it’s exactly where our crews do their best work. We coordinate scheduling and dispatch from the Fresno, Central Valley office, and our local teams know Dinuba’s neighborhoods, its building department, and the code triggers that catch homeowners off guard. If you want a written price before any work starts, call (559) 354-0579. We’ll walk the property, open the walls when needed, and tell you what the job actually costs.
Why Lodgewick ADU Fresno Is Dinuba’s Preferred Home Addition Contractor Company

Most Dinuba homeowners we meet have been burned once before. A contractor gave a low verbal number, then the price changed at the door. Or a crew never showed, and the permit sat unopened for months. Our answer to that is boring but specific: a written price before work begins, every time. The same goes for the 365-Day Done Right Promise, which states in writing that if the work isn’t right, we come back and make it right, no charge, within the guarantee period. Russ Delmar set that standard from day one, and every crew that works in Dinuba answers to it.
We know that adding a bedroom onto a 1960s home along Alta Avenue is not the same job as adding one onto a newer house near Dinuba High School. The older the home, the more likely we’re going to find cloth-wrapped wiring, a shallow slab, or framing that never met current lateral load standards. That’s not a problem, but it has to be priced. We inspect first, write allowances into the contract, and get every change approved in writing before we touch it.
When Dinuba homeowners call us, a live person answers. Not a voicemail loop, not a chatbot. Someone who can pull up your file, get a crew scheduled, and answer a straight question about your guarantee, 24 hours a day. That matters when you’ve been waiting three weeks for a callback from another company.
Bathroom Addition Contractor in Dinuba
A Bathroom Addition Contractor in Dinuba is someone who knows the difference between adding a bathroom inside a conditioned footprint versus extending the house on a new slab. For most Dinuba lots under 7,500 sq ft, the smartest move is carving a full bath and laundry space out of an existing bedroom or hall closet footprint, then tying the wet wall into the current plumbing stack. The other path is a true bump-out, where we pour a perimeter foundation, match the roofline, and run new drain and vent lines under the slab. Both work in Dinuba, and both have very different cost profiles.
Full Bath With Tub and Tile
A full bathroom addition inside the existing footprint in Dinuba typically runs $38,000 – $58,000. That number includes demo, a new subfloor in most 1950s-to-1970s homes, shower or tub plumbing, a 3-inch drain run, tile to the ceiling around the wet wall, a properly vented exhaust fan, and all required electrical. If the addition is a bump-out, the range moves to $55,000 – $85,000 because we’re pouring foundation, framing exterior walls, and sheathing and roofing the new volume before any finish work starts.
Three-Quarter Bath With Shower Only
When Dinuba homeowners want a fast second bathroom for a growing household, a three-quarter bath with a walk-in shower and low-profile pan usually lands between $28,000 and $42,000 inside the existing footprint. On a concrete slab, we break out only the area needed for the p-trap and shower drain, which keeps the demo contained. We also check the water pressure coming off the main line, because many older Dinuba homes have a half-inch service that can’t supply two showers at once without a pressure-boosting addition.
Bedroom Addition Contractor in Dinuba

A Bedroom Addition Contractor in Dinuba needs to know what the city will actually sign off on, especially when the lot is small and the existing home was built before current energy and seismic codes. We’ve added ground-floor bedrooms to 1950s ranches near the southeast side, tied into existing hallways, and brought the entire home’s panel and smoke-detector layout up to code as part of the permit. Dinuba homeowners often ask us for a multigenerational setup: a ground-floor bedroom with a nearby accessible bathroom. That’s a common, sensible addition here, and it’s one we price with all the upgrades listed in writing.
Ground-Floor Bedroom With Bath Access
A ground-floor bedroom addition in Dinuba typically runs $52,000 – $78,000 when it includes a reach-in closet, two egress windows, and a connecting or adjacent full bath. We plan the door swing and circulation space so the bedroom works for an elderly parent or a returning adult child without ever feeling like a conversion. If the exterior wall we’re tying into carries the roof load from a hip or gable above, we add a properly sized header and shear panel, and that cost is already in the written price.
Second Bedroom Above a Garage
Adding a bedroom above an existing garage in Dinuba starts around $78,000 and can reach $120,000 depending on whether we’re reinforcing the garage walls to carry a second story. On the east side of town, many pre-1980 garages have single-story 2×4 walls with no hold-down hardware. Current code requires us to sheath and strap those walls, often add new footings at the door opening, and run a second-floor load path before any framing goes up. It’s a bigger job than it looks, and we’d rather tell you that in the estimate than after the inspector visits.
Trusted Brands We Service in Dinuba
We work with prefab and panelized manufacturers like Abodu and Cover when a Dinuba homeowner wants a modular addition set in less time than a stick-built job. These units arrive with factory-built wall panels and engineered bracing, which can shorten site framing by several weeks on flat valley lots. For exterior cladding and trim, we typically specify James Hardie siding because it holds up to Dinuba’s hot, dry summers without warping, and it handles the occasional winter tule fog without rotting or swelling like wood. We can quote either path, prefab or site-built, in the same written estimate.
Common Home Addition Contractor Problems We See in Dinuba Homes
- Hidden aluminum wiring. Once we open a 1960s Dinuba wall, we often find cloth-wrapped aluminum branch wiring that no longer meets code. We write a repair allowance into the contract, and we don’t let a homeowner discover it after drywall is down.
- Seismic retrofits on old garage slabs. Dinuba inspectors routinely require hold-downs, anchor bolts, and shear panels before a garage-to-addition conversion passes because of nearby Sierra foothills fault lines. Skipping that step means tearing out finished work later.
- Flat-lot drainage. Most of Dinuba is dead flat, and a rare heavy rain will find the low corner of a new addition if we don’t slope the grade and add a perimeter drain line. We address drainage before the sill plate goes down.
- Undersized electrical panels. Many older Dinuba homes still run on a 100-amp panel. Adding a bedroom, bathroom, or second story usually forces a 200-amp service upgrade, and we price that as a named line item rather than a surprise.
Pricing for Home Addition Contractor in Dinuba, CA
A bathroom addition in Dinuba typically runs $28,000 – $85,000 depending on footprint and finish level. A ground-floor bedroom with bath access lands between $52,000 and $78,000. A bedroom above a garage runs $78,000 – $120,000 once seismic and structural work is included. Sunroom and bump-out additions on smaller Dinuba lots usually fall between $45,000 and $95,000. What moves the number most is what we find when the walls are open: old wiring, a slab without rebar, drainage corrections, or a service panel that needs upgrading. We inspect first, write those items as named allowances, and get your written approval before any additional work begins. Call (559) 354-0579 for a free estimate and a written line-item price.

FAQs About Home Addition Contractor in Dinuba
Dinuba requires a seismic retrofit before allowing most pre-1980 detached garages to be converted, which means adding hold-down hardware, anchor bolts, and shear panels to resist lateral movement from nearby Sierra foothills fault lines. You’ll also need a service panel upgrade if the garage runs on a subpanel fed from the main house. Call (559) 354-0579 and we’ll walk the garage and list exactly what the permit will trigger, in writing.
We write a repair allowance into the contract before work begins, and when our crew finds rot in the sill plate or termite damage in floor joists, we photograph it and give you a written price to repair it before we proceed. Nothing gets fixed without your approval in writing. That’s the Kingswell Way, and it’s the reason a Dinuba homeowner never sees a change order they didn’t authorize.
Yes, and most of the Dinuba lots we work on are under 7,500 sq ft. The key is staying within the setback lines and keeping the addition’s footprint tight against the existing house. A ground-floor bedroom with an adjacent or connecting bath typically fits on a side yard of 12 to 18 feet without needing a variance. Call (559) 354-0579 for a free lot walk and a written price.
Dinuba’s summer heat and winter tule fog mean your new addition should have R-19 wall insulation at minimum, R-30 or better in the attic, a properly sized ductless mini-split or tie-in to your existing HVAC, and an exhaust strategy for moisture that collects during fog season. We also spec low-e glazing on any west-facing windows, because the late-afternoon sun over Kings River country will overheat an underprepared room by August. Call (559) 354-0579 and we’ll quote the full energy package.
Yes, you need a structural permit, and Dinuba will also require a plan check for the second-floor load path and seismic hardware before you can begin. A second-story bedroom above a garage is not a simple remodel. We handle the full permit process, from drawings to inspection, and we will not let a homeowner skip it, because the risk of a failed inspection and torn-out work is too high.
