A home addition in Dallas typically costs between $90,000 and $250,000 depending on square footage, foundation work, and whether you’re adding a ground-floor room, a second story, or a sunroom. Most Home Addition Contractor in Dallas projects take 8 to 16 weeks from permit approval to final inspection. If you’ve been burned before by a contractor who changed the price at the door or never showed up, you’re not alone – and that’s exactly why Lodgewick ADU Dallas puts a written price in your hands before a single nail is driven.
Russ Delmar leads our Dallas team, and he’s spent more than a decade building additions, garage conversions, and ADUs across North Texas. We operate under The Kingswell Guarantee: a written price first, a real arrival window, a clean job site, and a written guarantee on every project.

Lodgewick ADU Builders is the ADU company of the Kingswell family. A lodge, if you think about it, is a small house on a larger property. That’s what an addition or ADU is: more livable space on a lot you already own. We match that space to your lot, your budget, and your timeline – and we put every commitment in writing before work begins.
Sunroom Addition
A Sunroom Addition extends your living space with a glass-walled room designed to capture natural light while shielding you from Dallas heat. When a full foundation-and-framing addition feels like too much square footage or too much budget, a sunroom gives you a bright, usable room at a lower entry point. Lodgewick ADU Dallas builds sunrooms that handle Texas summers with low-E glass, proper roof insulation, and ceiling fans sized for the room’s volume.
In Dallas, a sunroom addition typically runs $40,000 to $90,000 depending on glass package, roofing, and whether you need new HVAC runs. We’ll give you a written price before work starts – no surprises when the crew arrives.
Pre-Fab Sunroom Systems
We work with brands like Tuff Shed and prefab panel systems to keep your sunroom cost down without cutting corners on insulation. A prefab sunroom can cut 3 to 4 weeks off your build timeline compared to stick framing.
Dallas Climate Considerations
Dallas summers push 100 degrees for weeks at a time. We specify glass coatings and roof vents that keep a west-facing sunroom from turning into a greenhouse by 3 p.m., which matters if you’re adding the room on the side of the house that catches afternoon sun in Lakewood or Preston Hollow.
Room Addition Contractor
A Room Addition Contractor builds out new ground-floor living space: a den, a home office, a playroom, or a dining room extension done as a proper foundation-and-framing project. When your Dallas home feels like it’s shrinking but moving isn’t on the table, a room addition gives you the square footage you need without giving up your school district or your commute. Lodgewick ADU Dallas handles everything from foundation pour to roof tie-in to final paint.
A ground-floor room addition in Dallas runs $60,000 to $120,000 for a 200-to-400-square-foot space, depending on whether you’re adding a bathroom, what the foundation requires, and how much HVAC and electrical work is involved. We write the price down before any work starts.
Foundation Work in North Texas
Dallas sits on expansive clay soil that shifts with moisture. That’s not a problem if your addition’s foundation is designed for it – we specify piers and beams that match what your existing slab is doing, so you don’t end up with a crack at the seam five years later.
Matching Existing Architecture
If your house is a 1970s ranch in Richardson or a newer build in Murphy, a Home Addition Contractor - Duncanville would tell you the roofline and brick work need to match. We source brick and siding from local Dallas suppliers so the addition looks like it was always there, not bolted on as an afterthought.
Second Story Addition Contractor
A Second Story Addition Contractor adds an entire upper floor to a single-story home, roughly doubling your living space without expanding your home’s footprint. This is the right move when your lot is too small to build outward – common in older Dallas neighborhoods like Casa View or the M Streets – or when you want to preserve your backyard. Lodgewick ADU Dallas handles the engineering, the stair placement, the structural reinforcement, and the full build, all under one written guarantee.
A second story addition in Dallas typically runs $180,000 to $350,000 because you’re dealing with structural reinforcement of the existing first floor, roof removal and rebuild, stair construction, and complete mechanicals for the new level. The written price you get from us is the price you pay.
Structural Engineering and Permits
Dallas requires stamped engineering drawings before a second story goes up, and the permit review often takes 3 to 5 weeks. We handle the drawings, the permit package, and the inspections so you’re not chasing paperwork at City Hall.
Living in the Home During the Build
Most Dallas homeowners stay in the house during a second story addition, but the roof comes off. We sequence the work so the house is weather-tight every night, and we give you a dated schedule before demolition starts so you know which weeks are noisy and which weeks are quiet.
Garage Addition Contractors
Garage Addition Contractors build a new attached or detached garage, or expand an existing one into usable workspace, storage, or even a workshop with power and climate control. If your Dallas home has a one-car garage and you’ve got two cars plus a lawnmower plus a pile of tools, a garage addition solves a real daily problem. Lodgewick ADU Dallas builds garages that can also be permitted as future ADU space if you ever want to convert part of it later.
A garage addition in Dallas runs $35,000 to $75,000 for a standard two-car detached structure, with costs rising if you’re tying into the house, adding electrical service, or finishing the interior. We price it in writing before any material hits your driveway.
Detached vs. Attached Garages
A detached garage gives you more flexibility for future conversion into an ADU or workshop without touching the house’s roofline. An attached garage is cheaper to build because it shares one wall, but it changes how your house breathes and drains.
Dallas Zoning and Setback Rules
A Home Addition Contractor in Balch Springs knows Dallas has specific setback requirements for accessory structures, and some neighborhoods – especially around White Rock Lake and in East Dallas – have overlay districts with additional rules. We check your lot before we quote so your garage doesn’t end up three feet too close to the property line.
Bathroom Addition Contractor
A Bathroom Addition Contractor adds a full or half bath in a space that didn’t have one: a jack-and-jill bathroom between two bedrooms, a powder room off the kitchen, or a full bathroom in a finished garage or basement area. When a Dallas household of four shares one bathroom, adding a second changes the entire rhythm of the morning. Lodgewick ADU Dallas handles the plumbing rough-in, the waterproofing, the fixtures, and the tile – every trade, one written guarantee.
A bathroom addition in Dallas typically runs $25,000 to $60,000 depending on whether you’re adding a half bath or a full bath, how far the new drain line runs, and what finish level you choose. The written price covers the labor, the fixtures, and the materials before work starts.
Drain Line and Slab Work
Most Dallas homes sit on slab foundations, which means adding a bathroom means cutting concrete to run new drain lines. We do this cleanly, with dust control and a clear explanation of where the cuts will go before the saw starts.
Ventilation and Moisture Control
Dallas humidity is no joke, and a bathroom without proper exhaust turns into a mold problem within two years. We install and vent exhaust fans that actually move air outside, not into the attic.
Bedroom Addition Contractor
A Bedroom Addition Contractor builds a new sleeping room with proper egress windows, closet space, and HVAC integration. When a growing family needs another bedroom, or when an aging parent moves in and needs a ground-floor room with easy bathroom access, a bedroom addition is the answer. Lodgewick ADU Dallas builds bedrooms that meet Dallas code for egress, smoke detection, and energy efficiency – and that feel like part of the original house.
A bedroom addition in Dallas runs $50,000 to $110,000 depending on size, whether you’re adding an adjacent bathroom, and what the foundation and roof work require. You’ll get a line-item written price before any work begins.
Egress and Code Compliance
Dallas building code requires every bedroom to have a window large enough to exit through in a fire. It’s not a negotiable design detail, and we don’t treat it like one. Your bedroom addition will pass inspection the first time because we build to code from the first framing day.
HVAC Load and Comfort
Adding a bedroom changes your home’s heating and cooling load. We run the Manual J calculation so your existing system doesn’t get overtaxed, and if a mini-split or additional duct run is needed, that’s in the written price from day one.
Brands We Service
We build with materials and prefab systems from some of the most respected names in the industry because we’ve seen which ones hold up in North Texas weather. Mighty Buildings and Boxabl both produce panelized building systems that work well for accessory structures and additions where speed and consistency matter. We’ve built with their systems and know their install requirements, tolerances, and finish options – not just what the brochure says.
Plant Prefab is another brand we work with regularly, particularly for homeowners who want a high-design addition with a defined material palette and a known build schedule. Whether you have a specific brand in mind or you want us to match the right system to your Dallas lot and budget, we’ll walk you through the tradeoffs in plain English and price it in writing before work starts.
Signs You Need a Pro Right Now
- Your foundation is showing new cracks. A hairline crack can be normal settling, but a crack wider than a quarter-inch or one that runs diagonally from a corner of a window or door often means the soil under your slab is moving. In Dallas, where clay soil expands and contracts with rain and drought, this can shift from cosmetic to structural within a season.
- Your roofline sags or dips. If the ridge line of your roof isn’t straight, something underneath it is failing – a rafter, a beam, or a bearing wall. Adding square footage to a house with existing roof problems just multiplies the repair cost later.
- You’ve outgrown the house but not the neighborhood. If you’ve been pricing moving trucks and new mortgages and none of the math works, an addition may cost less than selling, buying, and moving. This is a planning conversation, not an emergency, but it’s better started before you’ve lost another year to indecision.
- Electrical service is maxed out. If your breakers trip when the microwave and the window AC run at the same time, your panel can’t support an addition without an upgrade. We’ll tell you honestly what the panel work costs and whether it’s worth doing now or phasing later.
- Water stains appear on the ceiling after rain. A roof leak doesn’t fix itself, and it gets more expensive every month it’s left alone. If you’re planning an addition, an unaddressed leak means you’re building new space under a compromised roof.
Our Process, Step by Step
- 1
Free site visit and honest conversation. We walk your Dallas property with you, look at your lot lines, your foundation, your roof, and your electrical panel, and we listen to what you actually need the space for. No pressure, no “sign today” tactics. Call (361) 204-4652 to schedule it.
- 2
Written price and scope, line by line. We give you a written estimate that breaks down the cost by category: foundation, framing, roofing, mechanicals, finishes. This is the price. If we find something unexpected later, we talk to you before we touch it – and you approve any change before it happens.
- 3
Permits and engineering. We pull permits for your Dallas addition, including any HOA or neighborhood requirements that apply. We handle the stamped drawings, the city review, and the inspection scheduling so you never have to stand in line at the permit office.
- 4
Build with a defined arrival window, clean job site, written updates. Our background-checked, uniformed technicians show up in the window we gave you, every day. The job site gets cleaned at the end of each day, and materials are stored neatly. You’ll never wonder who’s on your property or when they’re coming.
- 5
Final walkthrough and your written 365-Day Done Right Promise. We walk the space with you, point out everything we did and why, and hand you your written guarantee before we leave. If it’s not done right, we come back and make it right – that’s The Kingswell Guarantee, and it’s in writing on every job.
How Much Does Home Addition Contractor Cost in Dallas?
A home addition in Dallas runs anywhere from $25,000 for a small bathroom addition to $350,000 for a full second story. The most common projects we quote are ground-floor room additions at $60,000 to $120,000 and sunrooms at $40,000 to $90,000. Your actual number depends on square footage, foundation work, roof tie-in complexity, mechanical upgrades, finish level, and what your specific neighborhood requires for permits and setbacks.
What affects the price most in Dallas? Soil conditions drive foundation cost – if your lot needs deeper piers or more reinforcing steel, the concrete work goes up. Roof complexity matters too: tying into a simple gable is cheaper than tying into a hip roof with multiple valleys. And finish level is the wild card: a $40,000 room with builder-grade finishes looks very different from a $90,000 room with custom cabinets and upgraded flooring. We’ll show you line-item costs for each category so you can decide where to spend and where to save.
How do you avoid overpaying? Get a written price, not a verbal estimate. Ask what happens if the price changes – we’ll tell you it doesn’t, unless you change the scope after we start, and even then you approve the change order before any extra work happens. A free estimate from Lodgewick ADU Dallas includes a line-item breakdown, a timeline, and our Home Addition Contractor Maintenance Checklist for Dallas Homeowners, and you don’t have to decide anything on the spot. Call (361) 204-4652 to schedule yours.

Prefab systems can cut weeks off your build and reduce material waste. We’ll walk you through the tradeoffs between prefab and stick-built before you commit to anything, in plain English.

What we do is give you a real start date once your permits are approved and a defined arrival window for every workday after that. If you call (361) 204-4652 today, we can often put you on the schedule for a site visit within a few days, and we’ll give you a straight answer about when construction could realistically begin.

That’s on top of manufacturer warranties on materials and fixtures. The written guarantee is delivered before work begins, not after, so you know exactly what you’re covered for. If the work fails within the 365-day period, your return visit is free.
Start by thinking about how you’ll actually use the space: who’s in it, at what time of day, and what furniture or fixtures matter most. Clear the area where materials will be staged, tell us about any HOA requirements, and gather any questions you have about disruption, dust, or timing. We’ll walk you through the rest. Call (361) 204-4652 and we’ll schedule your free site visit to get started.
