Adding a bedroom or sunroom in Addison means working with the town’s zoning code, and that code is stricter than what you’ll find two miles down Belt Line Road in Farmers Branch. We know because we’ve pulled permits here, worked through Addison’s stormwater inspections, and framed additions on lots in the Arapaho corridor where the old 1950s slabs don’t always sit where the survey says they should. If you’re planning a home addition in Addison, TX, call (361) 204-4652 to get a written price before any work starts. That’s how we operate, and it’s why homeowners in Addison keep our number saved.

Why Lodgewick ADU Dallas Is Addison’s Preferred Home Addition Contractor

Homeowners in Addison call us because we give them a number in writing before the first permit application goes in. No estimate that drifts upward at the door, no scope that quietly shrinks after the deposit clears. Russ Delmar, who leads our team, built the Kingswell Way around one idea: a homeowner should never have to guess what a bedroom addition or sunroom will cost. We saw too many Addison residents burned by contractors who bid low, started digging, then discovered the lot was too small for what they promised. Our approach is different. We check the lot size against Addison’s 5,000 square foot ADU minimum before we ever quote a price. We confirm the setbacks, look at the roof height limit, and factor in the stormwater inspection that Addison requires before concrete gets poured. That’s why our prices hold.
Every Lodgewick crew member who works in Addison is background-checked and wears a uniform so you know exactly who is on your property. The 365-Day Done Right Promise backs every project: if the work isn’t right, we come back and make it right, and that commitment is in writing before we start. A live person answers our phone 24 hours a day, seven days a week, so when you call with a question about your build or your guarantee, you talk to a human, not a voicemail.
Bedroom Addition Contractor in Addison
As a Bedroom Addition Contractor in Addison, we handle everything from converting an unused dining room into a proper guest suite to building a 400 square foot attached addition with its own bathroom and kitchenette. The Addison angle matters more than people realize. The town’s zoning code allows accessory dwelling units only on single-family lots of at least 5,000 square feet, and only one ADU per lot. A bedroom addition that includes a bathroom and kitchenette crosses into ADU territory fast, which means the lot size and setback rules determine whether the project even gets a permit. We walk Addison homeowners through that distinction before they spend money on plans.
The Lot Check Comes First
Before we quote a bedroom addition in Addison, we pull the survey and confirm the actual lot dimensions. On a recent job in the Arapaho corridor, our crew had to design around a 12-foot rear setback after the client’s survey showed the original 1950s slab overhanging the property line by 4 inches. That kind of discovery changes everything: the foundation location, the roofline, the window placement. We used James Hardie fiber cement lap siding to match the existing exterior while keeping the new structure under Addison’s 25-foot height limit. The job passed framing and final inspections without a variance request, and the homeowner avoided a six-week zoning delay.
What a Bedroom Addition Costs Here
An attached bedroom addition in Addison typically runs $180 to $320 per square foot, which puts a 300 square foot room with a closet and en-suite bathroom between $54,000 and $96,000. A simpler bump-out bedroom without plumbing lands closer to $45,000 to $65,000 depending on foundation work and roof tie-in complexity. These are real numbers from projects we’ve priced in Addison, and the written quote you get from us reflects the same math.
Sunroom Addition in Addison
A Sunroom Addition in Addison is a smart path to more living area without triggering the same ADU requirements a bedroom with plumbing would. Addison’s code treats a non-habitable sunroom differently from a conditioned living space, which matters if your lot falls under the 5,000 square foot threshold. We’ve helped homeowners near Addison Circle and along Beltway Drive add three-season and four-season sunrooms that expand their footprint without forcing a variance fight. The typical Addison sunroom runs $38,000 to $72,000 for a 200 to 300 square foot build, depending on glass package, foundation type, and whether you want heating and cooling run to the space.
Stormwater Stops Work Before Framing Does
Addison requires a pre-construction stormwater BMP inspection before any foundation or concrete stem wall gets poured. Missing this inspection triggers a $500 re-inspection fee and stalls the rough-in schedule by about two weeks. We schedule it as part of our permit sequence, so the erosion control measures are in place and documented before the inspector drives over. Homeowners who try to fast-track their sunroom by pouring concrete early learn this lesson the expensive way.
Four-Season Versus Three-Season Decisions
If you want the sunroom to count as livable square footage for resale, it needs insulation, a proper foundation, and HVAC integration. That pushes the price toward the upper end of the range and adds about three to four weeks to the build. A simpler three-season room with thermal glass and no ductwork costs less and finishes faster. We’ll give you both numbers in writing so you can decide with real figures, not guesses.

Trusted Brands We Service in Addison
Lodgewick ADU Dallas works hands-on with prefab and modular systems from Boxabl and Plant Prefab, and we specify James Hardie siding on nearly every Addison addition because it handles North Texas heat and hail better than vinyl. Tuff Shed structures work well for detached storage and flex spaces, though they require the same setback review as any other structure in Addison. Because we stock and order these materials regularly, Addison customers aren’t waiting on backordered components. The lead time on a James Hardie order or a Boxabl unit impacts your schedule, and we quote that timeline up front.
Common Home Addition Contractor Problems We See in Addison Homes
- Lot size surprises. Builders quote a price per square foot without checking whether the lot even meets Addison’s 5,000 square foot minimum for an ADU, then the scope quietly drops to a non-habitable sunroom that costs nearly the same but adds no bedroom value.
- Setback violations on narrow lots. On a 45-foot-wide lot, forgetting the 5-foot side setback means a stop-work order and a slab tear-out. We’ve seen this happen. It’s a six-figure mistake that no homeowner should absorb.
- Stormwater inspection oversights. Addison’s pre-construction BMP inspection is easy to skip if your contractor doesn’t pull permits in this town regularly. The $500 re-inspection fee is bad enough; the two-week stall is worse when your family is already living through construction.
- Unwritten scope changes. Contractors who bid low then add change orders once framing starts. We put every commitment in writing before work begins, and the 365-Day Done Right Promise covers the build after it’s finished.

FAQs About Home Addition Contractor in Addison
Yes. Once a bedroom addition includes a bathroom and a kitchenette, Addison’s zoning code classifies it as an accessory dwelling unit, and that triggers the ADU permit path. The lot must be at least 5,000 square feet with a single-family home on it, and only one ADU is allowed per lot. The side and rear setbacks are 5 feet minimum, and the structure stays under 25 feet in height. Call (361) 204-4652 and we’ll check your lot against these rules before you spend money on drawings.
Addison’s pre-construction stormwater BMP inspection is the one that stops everything. The town requires it before any foundation or stem wall concrete is placed. If your contractor pours first, you owe a $500 re-inspection fee and the rough-in schedule slips about two weeks while the erosion control measures get documented and re-reviewed. We schedule this inspection as step one of the permit sequence.
You can build a sunroom, but not a bedroom. A detached structure with sleeping quarters, a bathroom, or a kitchenette is an ADU under Addison’s code, and a 4,800 square foot lot doesn’t meet the 5,000 square foot minimum. Calling it a sunroom on the permit application doesn’t change what the building actually is. The safer path on a smaller lot is a true non-habitable sunroom, which keeps you in compliance and still adds real living space.
Plan on three to six weeks for a 400 square foot bedroom addition permit in Addison. The review moves faster when the lot survey is current, the foundation plan addresses the soil conditions from your geotech report, and the drawings already show the 5-foot setbacks and the 25-foot roof height. What slows it down: missing the stormwater BMP submittal, a survey that’s out of date, or drawings that don’t clearly label whether the addition is an ADU. We handle the submittal package so the clock doesn’t run twice.
In Addison, the biggest price movers are concealed site conditions: an old 1950s slab that overhangs the property line, a soil test that requires deeper piers than the original quote assumed, or an electrical panel that’s out of code and has to be upgraded before rough-in. Material upgrades also move the number, but those are choices you make, not surprises we spring on you. Our written quote lists allowances for every line item, and any change gets priced in writing before the work proceeds. Call (361) 204-4652 for a free estimate on your Addison addition.
