An ADU (accessory dwelling unit) is a small, self-contained home built on the same lot as your main house – think a backyard cottage, a converted garage, or an attached suite with its own entrance. In Channelview, ADU work usually means one of three things: a ground-up unit in a generous backyard, a garage conversion where the slab already exists, or a bump-out addition that turns unused side yard into livable square footage. Russ Delmar leads our Channelview ADU work, and every project starts the same way: a written price before any work begins, a real arrival window, and a written guarantee on the job.

Why Channelview Homes Are Different
Channelview sits along the San Jacinto River and the Houston Ship Channel, which shapes almost every build decision here. The soil is largely clay-heavy, so foundations and slab work need more attention than in drier parts of Texas – we account for soil movement before we ever pour or frame. Summers are hot and humid, which means moisture control, proper ventilation, and impact-rated exterior materials matter for anything that will sit in the Texas sun year-round. Many Channelview homes were built between the 1960s and 1990s on larger lots than what you find closer to downtown Houston, so backyard ADUs are often a realistic option – not a cramped afterthought. If your property sits in a flood zone near the river or the channel, the FEMA elevation requirements and Harris County floodplain rules affect whether you build up or build out, and those rules often decide the difference between a feasible project and one that needs to be rethought. We walk through those constraints during the free estimate, not after you have committed.
Our Main Channelview Services
Most Channelview homeowners who call us are weighing two or three different ways to add space, and each path has its own set of tradeoffs. These are the three services we handle most often here.
Home Addition Contractor in Channelview
A home addition extends the footprint of your existing house – a new primary suite, a larger kitchen, a second living area – and it ties into your current roofline, foundation, and systems. In Channelview, older homes on pier-and-beam or slab foundations often need some leveling or reinforcement before the addition is framed, and we account for that in the written price up front. Homeowners near the Sheldon Road corridor and the neighborhoods east of Dell Dale Avenue often have the side-yard space to make an addition work without sacrificing the backyard. See how we handle Home Addition Contractor in Channelview work from first walkthrough to final inspection.
Garage Conversion Contractor in Channelview
A garage conversion turns an attached or detached garage into a finished living space – a rental unit, an in-law suite, a home office – without changing the home’s footprint. Channelview garages from the 1970s and 1980s often have slabs that are structurally fine but need moisture barriers and insulation upgrades before they meet living-space code. The conversion also has to pass through Harris County permitting, which treats a converted garage as a full dwelling unit when it includes a kitchen or bath. Our Garage Conversion Contractor in Channelview page covers what the process looks like start to finish.
ADU Builders in Channelview
A new standalone or attached ADU is a complete small home – kitchen, bath, sleeping area, separate entrance – built specifically as a second dwelling on your lot. In Channelview, the big advantage is space: many lots are wide enough for a detached unit set well back from the house, which gives privacy for a tenant or an aging parent. The permitting path goes through Harris County, and setback rules vary by lot size and zoning district, so we verify those details before the first design meeting. Our ADU Builders in Channelview page details the process and what to expect for a ground-up build here.

Brands We Service in Channelview
We work with the ADU brands and material systems that fit Channelview’s climate and lot conditions. For faster-turnaround backyard units, we specify Boxabl and Plant Prefab, both of which arrive as panelized or modular systems and assemble on-site in a fraction of the time of a stick-built unit. For garage conversions and additions, James Hardie siding and Tuff Shed shells are common choices because they hold up to Gulf Coast humidity. See our brands for the full range we install and service.

FAQs About ADU Company in Channelview
Most Channelview projects start with a free on-site estimate within a few business days of your call. After you approve the written price, design and permitting typically take 4 to 8 weeks before construction begins, depending on Harris County review times and the complexity of your lot. Call (361) 326-2313 to get the first walkthrough scheduled and see your timeline.
Harris County requires permits for any ADU, garage conversion, or addition that includes living space, plumbing, or electrical work. If your neighborhood has an HOA, its covenants may add restrictions on size, setbacks, or exterior materials – we check those before you commit to a design, so you are not surprised mid-project.
No, the price is locked in writing before work begins. The only exception is if you ask for a change in scope or if hidden site conditions – like a cracked slab or unexpected floodplain requirement – force a revision. In that case we document exactly what changed, why, and the revised price before any additional work happens.
