A home addition in Cedar Hill typically runs $190 – $380 per square foot depending on foundation work, roofline complexity, and interior finish level. That means a 400-square-foot bedroom suite usually lands between $76,000 and $152,000, while a modest 200-square-foot bump-out starts around $38,000. The slope of your lot changes everything here, which is why we price from an elevation survey, not a flat per-square-foot guess. Call (361) 204-4652 and we’ll walk your property, measure the grade, and hand you a written line-item price before any work begins.
Why Lodgewick ADU Dallas Is Cedar Hill’s Preferred Home Addition Contractor Company
We’re the ADU and home addition arm of the Kingswell family of home-service companies, operating under The Kingswell Guarantee since 2010. That guarantee is simple and it’s in writing on every project: a written price before work starts, a defined arrival window for every crew visit, a clean job site at the end of each day, and a written warranty with a free return visit if anything fails within 365 days. Russ Delmar leads our Dallas-Fort Worth team, and he holds every project to that standard.
Cedar Hill homeowners call us because the Cedar Hill terrain doesn’t forgive shortcuts. We’ve scoped additions in High Pointe, Lake Ridge, and Waterford Oaks where the grade shift between front and back yards exceeded six feet. That’s not a problem if you plan for it. It’s a $18,000 retaining wall surprise if you don’t. Our crews are local to the DFW metro, dispatched from our Dallas-Fort Worth office, and they know what the Cedar Hill building department expects before the first inspection.
Bedroom Addition Contractor in Cedar Hill
Bedroom Addition Contractor work in Cedar Hill means adding livable square footage to an existing home, usually to accommodate aging parents, a growing family, or a dedicated home office. The job involves foundation pours or pier installation, framing, roof tie-in, electrical, HVAC extension, drywall, and finish work. In Cedar Hill, a standard 12×14 bedroom with a closet runs $55,000 – $95,000 depending on whether you’re on a flat lot or dealing with the escarpment slope toward Joe Pool Lake.
Primary Suite Additions for Aging in Place
Many Cedar Hill homeowners in their 50s and 60s are adding ground-floor primary suites so they can avoid stairs later. These typically run 400 – 600 square feet and cost $130,000 – $220,000 when they include an accessible bathroom with a curbless shower. The foundation detail matters most here: on sloped lots, expect helical piers or a stepped footing system, which adds $12,000 – $25,000 compared to a flat-pad pour.
Guest Bedrooms and Flex Space
A simpler 10×12 guest bedroom with a standard closet can be done for $42,000 – $68,000 if the roofline doesn’t need serious modification. We tie into the existing gable whenever possible to avoid a full roof reframe. Cedar Hill’s 1990s brick ranches, common throughout High Pointe and older sections near Joe Pool Lake, usually accept a same-pitch roof extension without structural drama.
Sunroom Addition in Cedar Hill
Sunroom Addition work in Cedar Hill gives you a bright, climate-tolerant space without the full cost of a conventional room addition. A three-season sunroom with insulated glass, a slab-on-grade foundation, and a simple shed roof runs $45,000 – $85,000 for 200 – 300 square feet. A four-season sunroom with its own mini-split HVAC and insulated walls lands closer to $70,000 – $120,000. The escarpment orientation matters: south-facing sunrooms on Cedar Hill’s ridge lines catch brutal August heat, so we spec low-E glass and proper ventilation as standard, not upgrade.
Three-Season Sunrooms on Cedar Hill Slopes
On lots sloping toward Joe Pool Lake, a sunroom usually needs a stepped slab or short pier system. The good news: sunrooms are lighter than full additions, so foundation costs stay reasonable even on a 10% grade. Expect $8,000 – $15,000 for foundation work on a typical sloped Cedar Hill lot.
Four-Season Sunrooms with Independent Climate Control
If you want year-round use, we add a ductless mini-split heat pump and insulated knee walls. That typically adds $12,000 – $18,000. Cedar Hill’s freeze-thaw cycles are mild compared to North Texas’ northern counties, but an unheated sunroom still gets uncomfortable in January, so most homeowners choose the four-season route.
Trusted Brands We Service in Cedar Hill
We work hands-on with established ADU and addition building systems including Boxabl, Plant Prefab, and James Hardie siding. Boxabl’s foldable modules can cut framing time on a flat-lot bedroom addition by weeks, while Plant Prefab’s panelized walls handle Cedar Hill’s custom foundation requirements without sacrificing speed. We stock James Hardie plank and trim locally for Cedar Hill jobs so color-matched siding doesn’t stall a punch-list. When a brand’s system fits your lot and budget, we’ll say so. When it doesn’t, we’ll tell you that too, and explain why in writing.
Common Home Addition Contractor Problems We See in Cedar Hill Homes
- Pier depth underestimated near Joe Pool Lake. The limestone shelf under Cedar Hill dips and rises unpredictably. A contractor who drills shallow piers gets a passing foundation inspection but cracked drywall and sticking doors within two seasons. We core-sample before we quote so the pier schedule is right the first time.
- Tree Preservation Plan skipped before clearing. Cedar Hill’s arborist review board requires a Tree Preservation Plan before removing any heritage live oak. Skipping this triggers a stop-work order that can delay a project six weeks. We file the plan with the permit package, not after the chainsaw comes out.
- Flat $/sq ft quotes without an elevation survey. A six-foot grade change between your front and back yard adds $15,000 – $20,000 in retaining wall and stepped footing costs. If a quote doesn’t mention your survey, it isn’t a real quote. We survey every Cedar Hill lot before we price.
- HVAC tie-in underestimated on 1990s homes. Older Cedar Hill systems were sized for the original footprint, not an extra 400 square feet. We test static pressure and often spec a supplementary mini-split rather than overloading an aging condenser. It’s $6,000 – $9,000 well spent.

FAQs About Home Addition Contractor in Cedar Hill
Cedar Hill requires a full permit package including architectural drawings, a foundation plan stamped by a Texas-licensed engineer, an energy compliance report, and a site plan showing setbacks and tree locations. If your lot slopes more than 0.5 feet per 10 feet, you’ll also need a drainage plan showing how water moves after the addition. Permit review typically takes 3 – 5 weeks. We pull all permits for you and handle every correction. Call (361) 204-4652 and we’ll walk you through the exact timeline for your address.
Yes, most Cedar Hill residential zones require a minimum 10-foot side yard setback, and anything closer needs a variance from the Board of Adjustments. That process adds roughly 6 – 10 weeks to your timeline, and approval isn’t guaranteed. Some 1980s and 1990s subdivisions in Cedar Hill have zero-lot-line provisions that allow closer building, but you must verify against your specific plat. We check setback requirements before we draw plans so you don’t build toward a denial. Call (361) 204-4652 and we’ll verify your setback in the first conversation.
A three-season sunroom with no heating or cooling typically needs only a building permit. But if you add a mini-split, an electric heater, or a gas fireplace, you’ll need a separate mechanical and electrical permit, plus an inspection. Cedar Hill enforces this strictly, and failing to pull the mechanical permit means removing the unit and re-installing it after approval. We pull every permit the job requires, and we list them in your written price so there’s no surprise at inspection. Call (361) 204-4652 for a sunroom estimate with permit costs included.
Plan on 4 – 7 months for a 500-square-foot addition from permit issuance to final inspection. Foundation and framing on a sloped Cedar Hill lot takes 6 – 10 weeks, rough-in for plumbing, electrical, and HVAC takes 3 – 4 weeks, and drywall, finish carpentry, paint, and flooring take another 6 – 10 weeks. Weather in spring storm season can add a week or two. We give you a written schedule with milestone dates before we start, and if we miss a milestone, the guarantee covers the correction. Call (361) 204-4652 to get a real timeline for your specific scope.
The elevation change across your lot, by far. Cedar Hill sits on the eastern escarpment of the Texas Hill Country, and driveways or backyards often drop 10 – 20% toward Joe Pool Lake. That means pier-and-beam or engineered slab foundations with stepped footings, which run $12,000 – $25,000 more than a flat-pad pour on a Duncanville lot. Contractors who quote a flat $/sq ft without a survey will eat that cost, pass it to you as a change order, or cut corners on pier depth. We survey first, price second. Call (361) 204-4652 and we’ll send someone to shoot your grade before we hand you any number.
