AfterFast, Reliable Home Additions & ADU Across Reedley
Adding square footage to a Reedley home usually runs $45,000 to $130,000 for a room addition, while a fully permitted detached ADU lands between $90,000 and $220,000. Those numbers reflect what we actually see signed in this market, not a national average pulled from somewhere else. If you’re on a lot near Reedley High School, off East Manning Avenue, or tucked into the older streets west of G Street, the numbers shift with your foundation, your setback requirements, and whether the clay under your slab has been moving for fifty years. Call (877) 610-1318 and we’ll walk the property and put real numbers on paper.
Why Reedley Homeowners Choose Barrett & Sons Construction
Tom Barrett started this company in 1998, and the reason we keep getting calls from Reedley is simple: the owner’s name is on the truck, the owner’s sons run the crews, and the owner answers when something needs fixing. That matters more here than in a big metro, because Reedley is the kind of town where you’ll run into your contractor at the Save Mart on G Street and you’ll want to be able to look him in the eye.
Most of our Reedley customers are between 50 and 70, and a good number of them have already been through a bad experience with a national outfit that quoted one number on the phone and handed over a different bill when the job was done. Our Home Additions & ADU work doesn’t go that way. Every scope, every allowance, every change order gets written down before a nail moves. The permit inspector works for you, not for me, which is exactly why I like him on the job. And the 90-Day Done Right Promise is written on every contract: if it’s not done right, Tom comes back. One call.
We’re based out of the Fresno area and our crews serve Reedley locally, so scheduling doesn’t mean waiting on a crew from two counties over.
Our Home Additions & ADU Services in Reedley
ADU Design & Permitting
Reedley has its own rules on accessory dwelling units, and the City’s planning counter on G Street expects a complete package: site plan, structural calcs, Title 24 energy compliance, and soils work for that shrink-swell clay. We handle the design and the permit package together, because a plan that ignores the clay under the slab is a plan the city desks should bounce. We pull permits and get inspections signed on every eligible job.
Garage Conversion ADU
A garage conversion in the older neighborhoods off Manning Avenue - think the bungalows from the 1920s through 1960s - usually costs $30,000 to $80,000 depending on whether we’re rewiring, pouring a new slab section, or reframing a roof that’s been cooking under 105-degree summers for decades. These older garages were never insulated for living space, so we spec the envelope carefully. This is one of the fastest ways to add a rentable unit on a lot that already has a structure city staff can see from the street.
New Detached ADU
A new detached ADU in Reedley runs $90,000 to $220,000, and the wildcard is always the ground underneath. The heavy clay under most residential lots here shrinks and swells between dry summers and wet winters, which is why local foundation work means deeper perimeter beams and pre-wetting the subgrade before any slab pour. A contractor who doesn’t know Reedley’s clay will pour a slab that heaves by the third season. We know the clay.
Junior ADU & Interior Conversion
A junior ADU built inside your existing footprint - a converted den, a closed-off attached garage bay, a basement if the house has one - is the least expensive way to add a legal second unit in Reedley, and it typically falls in the $45,000 to $90,000 range with a kitchenette and separate entry. Interior conversions move faster through permitting than new construction, and for a lot of Reedley homeowners who want housing for an aging parent, that speed is the whole point.

Brands We Stand Behind on Reedley Jobs
We order materials you can look up. For bathroom and wet-area work inside ADUs and additions, that means Schluter waterproofing systems, Sterling fixtures, and Grohe rough-ins when the budget allows. For roofing over a new second-story addition or a sunroom, we install GAF systems with the warranties that go with them. Stocking local parts for these brands keeps turnaround tight when a Reedley job needs a change mid-stream, and it means you’re never stuck waiting on a truck from three states away.
Common Home Additions & ADU Problems We See in Reedley Homes
- Clay heave under post-tension slabs. The soil under Reedley expands when wet and contracts when dry, and slabs that weren’t engineered for that movement crack and lift. Foundation-adjacent additions need a soils review before plans are drawn, not after the footing is dug.
- Tule fog delays and inspection bottlenecks. Winter ground fog can sit over Reedley for weeks and stop exterior work cold. We sequence framing and concrete pours around that reality, which is why we recommend starting exterior-heavy work in spring or fall.
- Older bungalows with no room for modern systems. The wood-frame homes along the older residential core predate modern electrical and insulation codes. You can’t add a 400-square-foot ADU onto a 60-amp panel, so we plan the service upgrade into the budget from day one.
- Post-tension slab surprises in newer tracts. The newer subdivisions on Reedley’s edges were built fast over expansive clay, and tendons are often mapped poorly or not at all. Cutting into a slab without locating every tendon is the kind of mistake that turns a $50,000 addition into a $90,000 one, so we locate first and cut second.
Pricing for Home Additions & ADU in Reedley, CA
Here’s what we tell people at the kitchen table, because vague pricing doesn’t help anyone. A room addition in Reedley runs $45,000 to $130,000, and the spread depends on whether you’re adding a single bedroom with a bump-out or a full primary suite with plumbing. A garage conversion ADU lands between $30,000 and $80,000. A new detached ADU is $90,000 to $220,000, and a junior ADU or interior conversion usually falls between $45,000 and $90,000. The ground under your lot changes these numbers more than any factor we can control, because Reedley’s clay doesn’t negotiate. Every quote we give is free, written, and line-itemed, and any change that comes later arrives as a written change order before work happens.

We schedule Reedley projects around the tule fog season and the summer heat, which means the smartest start windows are spring and fall. Planning and permitting usually take longer than construction itself, and we can give you a realistic timeline once we see the lot and the city submittal package requirements. Call (877) 610-1318 and we’ll put dates on a calendar, not just promises in an email.
Yes, we work across all of Reedley’s 93654 zip code, including the neighborhoods near Reedley College, the older bungalows off Manning Avenue, and the newer tracts on the city’s edges. Wherever your lot sits, the same clay and the same fog apply, so local knowledge travels with the crew.
Only if you change the scope, and even then, nothing changes without a written change order. The allowance that isn’t on paper is a surprise waiting for a date, which is why every scope and allowance is written before we start, and every change arrives as a signed document before work proceeds. That’s the whole job, done the Barrett way.
Yes, the 90-Day Done Right Promise is written on every construction and remodeling contract we sign in Reedley, including full ADU builds and garage conversions. If something isn’t right inside that window, one call brings Tom back to make it right.
