ADU Construction in Richmond, TX
ADU construction in Richmond, TX plays out differently depending on which side of the city line your address falls on. In the historic core, established lots often have the depth and side yard that older neighborhoods were built with, which is exactly the room a detached garage apartment or small guest cottage needs behind the main house. Out in Pecan Grove, Long Meadow Farms, and Harvest Green, the lots are newer and the layout is tighter — and the first real conversation isn't about design, it's about what the HOA's architectural review committee will actually let you build.
ADU Construction for Richmond Homes
ADU construction in Richmond, TX plays out differently depending on which side of the city line your address falls on. In the historic core, established lots often have the depth and side yard that older neighborhoods were built with, which is exactly the room a detached garage apartment or small guest cottage needs behind the main house. Out in Pecan Grove, Long Meadow Farms, and Harvest Green, the lots are newer and the layout is tighter — and the first real conversation isn't about design, it's about what the HOA's architectural review committee will actually let you build.
We start every ADU with a feasibility review rather than a floor plan, because that's the honest order of operations in Richmond either way. Converting an existing garage is often the more direct path to a second unit, since the slab and structure are already in place and the site work is simpler than building detached from scratch. Utilities are typically trenched over from the main house, with separate metering available if you plan to rent the unit, and construction is scaled and sequenced like the small custom home it really is — foundation, framing, full mechanical systems, kitchen, and bath. Once feasibility is confirmed for your specific lot, the whole project is priced in a free itemized quote.
What's Included
- Feasibility review, permitting, and HOA/deed-restriction coordination
- Foundation, framing, and complete structural build
- Independent HVAC and utility connections
- Full kitchen and bathroom installations
- Premium interior and exterior finishes
ADU Construction in Richmond, TX.
Often, and it's usually a stronger starting point than building detached from scratch. Established lots in the historic core tend to have the depth and, in many cases, an existing garage structure that make a conversion or a modest detached unit realistic. City of Richmond permits apply in town, and we confirm what your specific lot supports — access, lot coverage, setbacks — before any design work begins.
It depends on the HOA, and we won't tell you otherwise. In Richmond's master-planned sections, the architectural review committee typically has real say over whether a detached second unit gets approved, what it can look like, and where it can sit on the lot. We review your specific HOA's guidelines before design starts, so you know what's realistic before investing in plans rather than after a rejection.
Whether you're converting an existing garage or building detached from the ground up is the biggest factor, followed by the utility runs needed, the finish level in the kitchen and bath, and any extra site work a tighter master-planned lot requires. We treat the project like the small custom home it is, walk your property, and provide a free itemized quote so every driver is visible before you commit.
Water, sewer, and electrical typically get trenched over from the main house, which keeps the project simpler whether you're on an in-town lot or a newer HOA lot. If you plan to rent the unit, separate metering is available. We evaluate the main house's existing capacity as part of feasibility, since an older in-town home sometimes needs a panel or line check before the ADU can tie in.
