A home addition in Fresno means adding a permitted, attached living space to your existing house: a new bedroom, a larger kitchen, a sunroom, a second story, or a garage conversion tied into the main structure. The total cost in Fresno typically runs $180 to $340 per square foot, so a 400 square foot addition lands between $72,000 and $136,000, and smaller spaces like a bathroom addition usually start around $45,000. Lodgewick ADU Fresno has built additions across the Fresno area since 2010, always with a written price before work begins and the 365-Day Done Right Promise in writing on every project. Russ Delmar leads our Fresno team. Call (559) 354-0579 and a live person answers, day or night.
Most Fresno homeowners call us for one of two reasons: they have outgrown their house, or they have been burned by a contractor who promised one number and delivered another. We solve both problems. Every addition we build starts with a fixed, written price and a defined arrival window. Every crew member is background-checked and uniformed. And every project ends with a written guarantee, not a handshake. That is how we have built additions as a Home Addition Contractor in Fresno in neighborhoods from Sunnyside to Tower District without the price changing at the door.
Here is what matters when you compare home addition contractors in Fresno: get the price in writing before work starts, confirm who is doing the work, and make sure the guarantee says what happens if the work fails. We put all three in the contract. We also answer questions honestly. A second story addition in Fresno, for example, typically requires structural work that a simple bump-out does not, and we will tell you that on the first call rather than after the walls are open.
Sunroom Addition
A Sunroom Addition extends your living space with floor-to-ceiling natural light, usually off the back of the house, and in Fresno it costs between $35,000 and $90,000 depending on size, foundation, and whether you want it heated and cooled. Most Fresno homeowners add a sunroom because they want a bright sitting room, a plant room, or a breakfast nook without the full cost of a conventional room addition. Lodgewick ADU Fresno handles the permit drawings, foundation, framing, windows, and finish work under one written price. We use James Hardie siding when the exterior needs to match the existing house, and we specify Low-E glass so the room stays usable during Fresno’s 100-degree summers instead of turning into a greenhouse.
What Fresno’s climate means for your sunroom
Fresno gets over 100 days of triple-digit heat in a typical year, and a poorly glazed sunroom absorbs that heat all afternoon. We orient the windows for morning light, shade the west wall, and size the HVAC or ductless system to hold a comfortable temperature. If the sunroom connects to the main house without a proper thermal break, you also learn quickly that your central air now has to cool an extra 250 square feet of glass. That is why we pull the addition permit and run the load calculation, not just frame a patio cover and call it a room.
Matched to the existing house
A sunroom should look like the house grew it, not like a greenhouse bolted to the back wall. We match rooflines, stucco texture, casing profiles, and floor heights so the transition feels original. When you stand inside, the ceiling height and window sill lines stay consistent with the rest of the home. That level of finish is part of the written price, not an upgrade added later.
Room Addition Contractor
A Room Addition Contractor builds new living space onto the footprint of your home, and in Fresno a ground-floor room addition typically runs $180 to $280 per square foot, meaning a 300 square foot family room or office lands between $54,000 and $84,000. If you’re in the area, you may also want to consider our Home Addition Contractor in Clovis for nearby projects. Homeowners call Lodgewick ADU Fresno for this when a growing family needs a playroom, a home office, a music room, or a larger dining space and the existing layout has nowhere left to absorb it. We handle the architectural drawings, structural engineering, permit approval with the City of Fresno, and the full build. Because we are the ADU company of the Kingswell family, we also build additions that can later function as an accessory dwelling unit with its own entrance, kitchenette, and bathroom.
When a room addition costs more
Two things move the price on a room addition in Fresno: site conditions and finish level. If your foundation needs piers or the gas and electric panels are already maxed out, the number changes, and we will show you the line item before you sign. Finish level is the other big mover: a room with a $3 per square foot carpet and builder-grade windows costs less than one with a $9 per square foot engineered floor and a custom window package. We price the job to the finish you actually want, not a teaser allowance that gets upgraded later.
The Kingswell way to price a room addition
Most Fresno homeowners who hire us have already sat through a contractor’s vague verbal estimate that somehow grew by 20 percent once the crew showed up. So we do the opposite. We walk the property, take measurements, check the panel and foundation, and write a fixed price that covers the permit, materials, labor, and the guarantee. That price is in your hand before any work starts, and it does not change unless you change the scope. No change orders at the door.
Second Story Addition Contractor
A Second Story Addition Contractor builds upward instead of outward, and in Fresno a second story addition typically runs $250 to $400 per square foot, with a full second story on a 1,000 square foot footprint starting around $250,000 and moving up from there with finish level. This is the right move when your lot is too small to build out, or when you want to preserve the backyard for the kids and the garden. Lodgewick ADU Fresno has completed second story additions across Fresno, including the historic districts where the City’s planning rules care about preserving the street-facing facade. Russ Delmar walks every second story job personally before we price it, because the structural questions solve themselves differently on a 1940s bungalow than on a 1990s tract home.
What a second story does to your existing structure
Adding a floor means the existing walls and foundation now carry twice the load they were built for, and in Fresno that often triggers a structural upgrade, not just a framing package. We check the foundation, the lateral system, and the existing headers before we write the price. If the original house was built with 2×4 walls on a slab, we will tell you what the engineer requires before the permit is pulled, not after demolition starts. That candor saves money and keeps the project honest.
Living through the construction
A second story addition is invasive in a way a ground-floor bump-out is not: the crew has to open walls to tie in the new floor system, run plumbing and electrical up through the existing chase, and sometimes move you out of a portion of the first floor. We sequence the work so the house stays secured and the family keeps a functioning kitchen and one bathroom as long as possible. The written price includes that sequencing plan, and the written guarantee covers the new structure for the full 365-day period.
Garage Addition Contractors
Garage Addition Contractors convert or extend an attached or detached garage into livable space, and in Fresno a garage addition or conversion typically runs $120,000 to $220,000 depending on whether you are finishing the existing shell, extending it, or adding living space above it. This is the most popular path for Fresno homeowners who want an ADU, a media room, or a multi-generational suite without surrendering yard space, and we also serve clients looking for a Madera Home Addition Contractor. Lodgewick ADU Fresno works with the existing foundation and framing where possible, which holds the price down, and we handle the City of Fresno permit path for garage conversions, including the separation and fire-rating requirements that surprise DIYers.
We also build above existing garages. A garage-top second story is a clean way to add a primary suite or two bedrooms while keeping the garage below for cars and storage. That project almost always requires a structural upgrade to the garage walls and slab, and we will show you that cost in the written estimate before you commit. If the garage is detached and you want it to function as a true ADU with its own kitchen and bathroom, we will price it so that it can be rented legally in Fresno, not just used as a guest room.
From garage to legal living space
A garage conversion in Fresno is not a paint-and-carpet job. The City requires insulation, a proper heating and cooling source, egress windows, and in most cases a fire separation from an attached garage. We pull those permits and build to code so the space can be legally counted as living area on a future appraisal and insurance policy. That is the difference between an addition and an expensive storage room with drywall.
Above-garage additions
When you add a second story above the garage, the stairwell becomes the architectural problem to solve. We design the stair so it does not eat the garage entry or the existing living room, and we match the roof to the main house. The result reads as original construction from the street. Most above-garage additions in Fresno take four to seven months from permit to final inspection, and we will give you that timeline in writing with the price.
Bathroom Addition Contractor
A Bathroom Addition Contractor adds a full or half bath to a home that has too few, and in Fresno a full bathroom addition typically runs $45,000 to $80,000 depending on whether plumbing can tie into an existing wet wall or needs new drain lines cut through the slab. The most common trigger in Fresno is a family of four sharing one bathroom, followed by an aging-in-place setup that needs a zero-threshold shower on the ground floor. Lodgewick ADU Fresno handles the plumbing, waterproofing, tile, fixtures, and the permit, and we build the bathroom as a permitted addition so it adds value to the home on a future sale, not just relieves the morning line.
Where the plumbing is makes the price
If your new bathroom sits directly above or beside an existing bathroom or kitchen, the plumbing cost stays low: we tie into the existing drain and vent system and run new supply lines a short distance. If the addition is on the far side of the house, we may need to cut the slab, run new waste lines, and add a cleanout, and that is where the price moves. We will show you the plumbing plan and the line item in the written price, so you know what you are paying for before we cut concrete.
Waterproofing done right
A failed shower pan is one of the most expensive failures in a Fresno home because the water travels through the floor system before you ever see a stain. We waterproof every shower with a full membrane system, flood-test the pan for 24 hours before tile goes in, and document it with photos. The water-proofing is covered under the 365-Day Done Right Promise: if the shower leaks within the guarantee period, we come back and fix it, no invoice.
Bedroom Addition Contractor
A Bedroom Addition Contractor adds a sleeping room that meets the legal definition of a bedroom, and in Fresno a ground-floor bedroom addition typically runs $54,000 to $95,000 for a 300 to 400 square foot room, including the permit, egress, closet, and finish work. Families call Lodgewick ADU Fresno for this when a new baby makes the two-bedroom house feel like a closet, or when an aging parent moves in and needs a ground-floor bedroom with a nearby bathroom. A legal bedroom in Fresno requires an egress window large enough to escape through, a closet, and a heat source, and we build all three to code the first time.
What makes a room a legal bedroom
In Fresno, you cannot call a room a bedroom in a listing or an appraisal without the egress window, the closet, and the heat source. We size the egress window to the City’s minimum opening, which matters in an emergency, not just in a permit review. If the bedroom connects to the main house without a door, it is not a bedroom; it is a bonus room. We will tell you which one you are building before we write the price, because the difference affects the resale value.
Bedroom plus bath combinations
Many Fresno homeowners pair a bedroom addition with a small en-suite bathroom, which gives the room privacy and makes it function as a primary suite or an in-law setup. That combination typically lands between $100,000 and $150,000, and it changes the plumbing plan, so we price it as one project rather than two. The written price covers both spaces, and the written guarantee covers both spaces for the full year.
Brands We Service
We build with established ADU and addition material systems, and we match the brand to your lot, budget, and timeline rather than pushing one system on every job. Abodu produces a precision-built prefab ADU shell that works well on flat Fresno lots with easy crane access, and we handle the site work, foundation, and finish-out around the Abodu unit. Cover builds panelized, steel-framed units with a clean architectural look, and our crews have assembled them on tighter urban lots in Fresno where the crane schedule is the constraint. Dvele is a higher-end prefab with a health-focused material spec, and we recommend it for homeowners who want a very tight building envelope against Fresno’s summer heat.
James Hardie fiber cement siding goes on most of our ground-up additions and sunrooms because it is the most durable exterior product for the Central Valley’s dry heat and occasional downpour, and it takes paint cleanly. Whether you arrive knowing exactly which brand you want or you want our read on what fits your home, we will build the addition around the right system and put the whole thing in one written price. If you already have a brand in mind, tell us on the call and we will speak to it directly.
Signs You Need a Pro Right Now
- Cracks in the walls or ceilings that are growing. Movement that continues after the summer dry-out suggests a structural problem, and if you add a story or a heavy sunroom on top of a compromised wall, the problem gets transferred into the new work. We check the foundation and wall plane before we write any price.
- Your panel is already maxed out. A home addition with its own bedroom or bathroom needs new circuits, and an old 100-amp panel may not have the capacity. If you are running extension cords in the house you plan to add onto, the electrical work has to happen first, not as a surprise change order.
- The City has flagged an unpermitted room. Fresno homeowners sometimes inherit a “bedroom” that was never permitted. If you are selling, refinancing, or adding onto an unpermitted space, we can help you understand the correction path and build the new addition in a way that does not make the old problem worse.
- Your family has outgrown the house and the rental math does not work. If moving to a bigger Fresno house would cost $150,000 more than staying put, an addition starts to make real financial sense. We will give you an honest number and tell you when the math favors moving instead.
- Water is pooling at the foundation line. Fresno’s dry season hides drainage problems, but the winter rains expose them. If you have standing water at the house line, that condition has to be fixed before an addition goes on that wall or the new space inherits the moisture problem.
Our Process, Step by Step
- 1
Walk-through and written price. We come to your Fresno home, take measurements, check the foundation, panel, and roof, and discuss what you need the space to do. Then we write a fixed price that covers the permits, materials, labor, and the written guarantee. That price is yours before any work starts, and it does not move unless you change the scope.
- 2
Plans and permit. We prepare or coordinate the architectural drawings and structural engineering, submit to the City of Fresno, and manage the permit review. We do not start work on an unpermitted foundation; we build to the code that protects the resale value of your home.
- 3
Pre-construction walk. Before the crew arrives, we walk the job with you and the lead carpenter to mark the addition footprint, confirm the access path, and set the arrival window for every day of the build. The crew shows up in that window, uniformed and background-checked.
- 4
Build and daily clean-up. The Kingswell Way means the job site gets cleaned at the end of every day, not just at the end of the project. We sequence the work to keep your house livable and secure, and we keep you informed when inspections happen.
- 5
Final walk and written guarantee. When the final inspection passes, we walk the addition with you room by room and hand you the written 365-Day Done Right Promise. If anything is not right within the guarantee period, we come back and make it right at no charge. That is the whole point of the guarantee.
How Much Does Home Addition Contractor Cost in Fresno?
A typical home addition in Fresno runs $180 to $340 per square foot, which means a 400 square foot ground-floor addition lands between $72,000 and $136,000. A sunroom addition runs $35,000 to $90,000. A bathroom addition runs $45,000 to $80,000. A second story addition starts around $250,000 for a full floor. A garage conversion or garage addition runs $120,000 to $220,000. These are real Fresno market numbers, not teaser ranges designed to get you on a call.
What moves the price: the condition of your foundation, the distance from the new space to existing plumbing, the finish package you choose, and whether the project needs structural work. A bathroom on the far side of the slab costs more than one beside an existing wet wall. A second story costs more than a ground-floor bump-out because the structure under it has to be upgraded. We show you each line item in the written price, so you see exactly what you are paying for.
How to avoid overpaying: get a written price before work starts, ask what happens if the price changes, and confirm the guarantee in writing. A free estimate from Lodgewick ADU Fresno includes the walkthrough, the measurements, and a fixed written price, plus guidance from our Home Addition Contractor Maintenance Checklist for Fresno Homeowners. You do not need to hire us to get the number, and the number does not change if you do.
