ActiveYards Home Additions & ADU: The Houston Owner’s Guide
ActiveYards home additions and ADU construction in Houston typically runs $45,000 to $130,000 for a complete build, and Bradford Remodeling Co Houston handles the full scope from foundation to final trim. Most Houston homeowners start this conversation after realizing their existing yard footprint is too small for the addition they actually need, or after a storm season exposed problems with how their current space drains and holds up. The trigger is usually practical: a growing household, aging parents moving in, or a home office that has outlived the spare bedroom. You want a straight number and a clear scope before anyone swings a hammer, and that is exactly how we run this.
One thing to understand up front: Bradford Remodeling Co Houston is an independent contractor, not affiliated with ActiveYards. We build home additions and ADUs that integrate with ActiveYards outdoor structures and fencing systems when the project calls for it, and we are familiar with how ActiveYards components fit into a larger residential build. That means we can plan the addition around your existing ActiveYards layout instead of treating it as an afterthought.
Key Takeaways:
- Full home additions in Houston run $45,000 to $130,000; ADUs run $90,000 to $220,000 depending on square footage and finishes.
- We provide a written price before any work starts, with no numbers that move at the door.
- Every completed project carries the 365-Day Done Right Promise in writing.
- Curtis Lane runs the scope review personally, so the number you get is the number you build to.
Which ActiveYards Models This Applies To
ActiveYards manufactures a range of outdoor structures: pergolas, pavilions, fencing, and yard enclosures built on extruded aluminum framing systems. When we build an addition or ADU around an existing ActiveYards installation, the compatibility question is less about which ActiveYards model you own and more about how your existing yard structure connects to the new foundation and roofline. The ActiveYards aluminum post system measures differently depending on the series: the residential lines use a 2-inch by 2-inch post profile on some products and a 2-inch by 3-inch on others, and that offset matters when you are tying a new roofline into an existing ActiveYards pavilion.
If you have the original ActiveYards paperwork, look for the series name: the Yardistry line, the Aluminum Pergola line, and the Vinyl Fence line all use different mounting hardware and post spacing. Houston homeowners frequently discover this the hard way when a general contractor orders the wrong post bracket and delays the whole project for two weeks waiting on a part. We verify the profile and spacing during the estimate walkthrough so that mistake does not happen on our jobs. For OEM versus aftermarket: ActiveYards uses a proprietary powder coat on their aluminum extrusions, and aftermarket touch-up paint never quite matches after a few Houston summers. We spec OEM hardware for anything visible and use structural aftermarket components only where they go behind the finished surface.

Signs Your ActiveYards Home Additions & ADU Is Failing
Homeowners in Houston do not usually frame this as a “failing ActiveYards part.” They notice the space is not working, and the problem traces back to how the existing structure was built or tied in. Here is what we actually see on job sites across the metro:
- Post base corrosion at grade level. Houston’s clay soil expands and contracts with every wet-dry cycle, which works post brackets loose and lets water sit against the aluminum. The powder coat eventually fails at the base, and the post starts to oxidize where you can see it flaking.
- Roof tie-in leaks where the addition meets the existing ActiveYards structure. The flashing detail between an ActiveYards aluminum roofline and a new stick-built addition is where water gets in. We see this often after the first heavy spring storm. The sealant fails, water runs down the beam, and the ceiling inside the new space shows a water stain within a month.
- Out-of-square door and window openings. If the original ActiveYards structure was not installed on deep enough footings, Houston’s shifting soil moves it over time. By the time you notice the door dragging, the frame has already twisted enough that a standard-size replacement door will not fit without shimming and re-plumbing the opening.
- Uneven concrete around the existing posts. Heaving slabs are a Houston trademark. When the patio slab around an ActiveYards pavilion heaves, the posts lean, the roof pitch changes, and water stops draining. It looks like an ActiveYards problem. It is a foundation problem. We fix both in scope.
- Fascia and soffit separation along the transition. Where the new addition meets the ActiveYards eave line, differential expansion between aluminum and wood framing shows up as a visible gap by the second or third season. Caulk hides it for a few months. Properly re-framed transition does not.

AfterReplacement Cost & What’s Included
A complete home addition in Houston runs $45,000 to $130,000 depending on square footage, foundation work, and finishes. An ADU runs higher, $90,000 to $220,000, because it includes a full kitchen or bath rough-in, subpanel work, and its own HVAC. When the project involves repairing or tying into an existing ActiveYards structure, the additional line item for re-flashing, post collar replacement, and structural correction typically lands between $1,500 and $6,000 depending on how much of the original installation has to be undone and redone.
Every number we give you is in writing before work starts. That written price includes the full scope: demolition, foundation, framing, rough-in, finishes, cleanup, and the signed 365-Day Done Right Promise in your hand at job close. The range exists because a 300-square-foot bump-out with no plumbing and a LVP floor costs less than a 700-square-foot ADU with a full bath and custom cabinetry. What does not change: the price we write is the price we build to. If we find a condition during the project that adds scope, we price the change order in writing before we touch it. No surprises at the final invoice.
| Houston Project Type | Installed Price Range | What Moves the Number |
|---|---|---|
| Home Addition (300-700 sq ft) | $45,000 – $130,000 | Foundation type, structural steel, finishes, plumbing scope |
| ADU Construction (full build) | $90,000 – $220,000 | Kitchen/bath count, separate utility hookups, site access |
| Garage Conversion | $30,000 – $80,000 | Slab condition, insulation, window/door re-framing |
| ActiveYards tie-in / structural repair | $1,500 – $6,000 | Post condition, flashing scope, how much demo is required |
We work with KraftMaid, Wellborn, Cambria, and Silestone for interior finishes when the addition includes a kitchen or bath. We also stock ActiveYards-compatible structural hardware on the truck for tie-in work, so a post repair does not stall the whole build waiting on a delivery.
DIY or Call Us?
There is a safe version of DIY here, and there is a version that puts a roof on you. Checking the visible condition of your ActiveYards posts is fine: look for powder coat flaking, rust staining at the base, and any lean you can spot with a level. You can also run a hose along the transition between the existing structure and any new roofline to see where water sits. Those observations are useful when we walk the property.
What you should not do is attempt to reset a leaning post, re-flash a roof transition, or cut into an existing ActiveYards beam to make room for new framing. Aluminum under compression from a shifted roof load will release that energy without warning when you cut it, and the roof section can drop before you are clear. This is trade work with real consequences: structural framing, roof tie-ins, and foundation corrections are not weekend projects. Houston’s soil makes everything move, and every correction you make to one post shifts load to the next. Curtis Lane has been reading these scopes in the Houston market for over a decade, from gut-rehab kitchens in Montrose to full structural repairs after storm season. Straight scope, straight number, that is the whole conversation. Call (940) 289-7658 for a free estimate, and we will put it in writing.
FAQs
A properly built addition in Houston should last 50 years or more with routine maintenance, but the tie-in details and foundation work are what actually determine lifespan. The frame is only as good as the footing it sits on, and Houston’s clay soil is hard on everything. We build footings to the local code depth, we re-flash every transition, and the 365-Day Done Right Promise covers the first year of the structure in writing. After that, the materials themselves carry manufacturer warranties from GAF, James Hardie, and Therma-Tru, which we document for you at close. Call (940) 289-7658 if you want an exact number for your lot.
Yes, in most cases the existing ActiveYards structure can be salvaged and re-integrated into the new build for less than a full replacement would cost. What determines whether repair makes sense is the condition of the post bases and the roof transition. If the posts are sound and only the flashing failed, we correct the flashing and move on. If the posts are corroded through at the base, the repair cost gets close enough to replacement that you should make an honest comparison. We will show you both numbers in the written estimate. Call (940) 289-7658 to get that comparison.
A standard addition takes 3 to 6 months from permit to final walkthrough, and an ADU takes 4 to 8 months depending on utility work and site access. Houston’s permitting calendar and weather both affect the schedule, and we factor both into the written timeline we give you with your price. The pace is set by inspections: foundation, rough framing, rough electrical, rough plumbing, insulation, and final. We pull all the permits, schedule every inspection, and refuse to build a day ahead of the inspector’s sign-off. Call (940) 289-7658 and we will put the schedule in writing alongside the price.
We stock the structural hardware needed for tie-in work: post collars, bracket kits, flashing material, and sealants rated for the Houston climate. When a repair involves replacing a visible ActiveYards component like a post or beam section, we order OEM from ActiveYards directly so the powder coat and extrusion profile match. That order typically adds a week to the schedule, and we tell you that before we write the estimate. Call (940) 289-7658 to find out whether your project needs stock hardware or an OEM order.
