Custom Home Builders in Southern Maryland: A 2026 Comparison Guide
So you've decided you'd rather build than buy resale, and now you're staring at a dozen unfamiliar builder names, trying to figure out who's actually reputable, who builds where, and who's going to disappear halfway through your project.
That's a fair worry. Southern Maryland's new construction market is really two different worlds living side by side: large production and semi-custom builders putting up whole neighborhoods, and small, local custom builders who might build five homes a year on land you already own.
Both paths can get you a great home. They just work differently, cost differently, and take different amounts of time to get there. This guide breaks down who's building in Calvert, St. Mary's, and Charles County right now, what each type of builder is actually good at, and how to think through the decision before you sign anything.
Southern Maryland's new construction pipeline has stayed active through 2026, even as resale inventory has crept up and buyers have gained a little more room to negotiate. That combination has actually pushed some builders to compete harder on lot selection, upgrades, and incentives instead of just price, which is good news if you're shopping around.
Who Are the Custom Home Builders in Southern Maryland?
Southern Maryland has two main categories of builders. National and regional production builders such as D.R. Horton, Lennar, Stanley Martin Homes, Ryan Homes, Caruso Homes, and Schaefer Homes build entire communities in Calvert, Charles, and St. Mary's County, usually with a set list of floor plans and faster, more standardized timelines. Alongside them is a smaller group of local, family-owned custom builders — companies like Marrick Homes, Wilkerson Homes, St. Marie's Builders, and about a dozen others in this guide — who build on your land or in smaller local communities, with more flexibility on design and a longer, more personal process.
Neither type is automatically the better choice. It comes down to your land, your budget, your timeline, and how much you actually want to customize.
I'm Amanda Holmes, a Realtor with eXp Realty serving St. Mary's, Calvert, and Charles Counties, and this exact question comes up in almost every buyer conversation I have these days. Here's how the builder landscape actually breaks down.
Production and Semi-Custom Builders Building Communities Here
If you don't already own land, this is usually the simpler starting point. The lot, the plans, and the pricing structure are already set, so you're choosing from what's available rather than building from scratch.
D.R. Horton — a national builder active in current communities in both St. Mary's County and Charles County.
Lennar and Stanley Martin Homes — both currently building in Charles County.
Ryan Homes — also active in Charles County.
Schaefer Homes — building at Kinsey's Ridge and Wyatt's Ridge in Calvert County.
Quality Built Homes (QBHI) — a Prince Frederick-based production and semi-custom builder with communities and a Build On Your Lot program spanning Calvert, Charles, and St. Mary's County, with an emphasis on energy-efficient construction.
Caruso Homes — doesn't have a named community currently open in the tri-county area, but offers its Build On Your Lot program across all three counties if you already have land.
For specifics on pricing, current communities, and what's available right now, my Charles County new construction guide, St. Mary's County new construction guide, and Calvert County new construction guide go deeper county by county.
Local and Custom Builders Serving Southern Maryland
This is where Southern Maryland's building scene gets more interesting. Several of these companies have been building here for decades, often out of the same family for two or three generations.
Builders working across multiple counties:
Marrick Homes — Prince Frederick-based, building in Southern Maryland since 1984, with communities and build-on-your-lot options in Calvert and Charles County.
Southern Maryland Home Builders and Developers — Calvert County-based, building new construction since 2002, with homesites in Huntingtown, Dunkirk, Chesapeake Beach, and several other Calvert communities.
W.M. Davis, Inc. — Hollywood-based, founded in 1987, builds custom homes across St. Mary's, Calvert, and Charles County alongside larger commercial development work.
Rainbow Construction — Waldorf-based, with roots going back to the 1960s and residential building in Southern Maryland since the late 1980s, offering both semi-custom and fully custom homes.
County-rooted custom builders:
Wilkerson Homes — family-owned and Hughesville-based, building on 1- to 30-acre lots in Charles County, including multi-generational floor plans.
Litz Custom Homes — based in White Plains, building on land you already own across Charles, St. Mary's, and Calvert County.
St. Marie's Builders — Hollywood-based, focused on high-end custom and waterfront homes in St. Mary's and Calvert County, including specialty structures like horse barns and pool houses.
Wood Construction — Mechanicsville-based and second-generation, offering full-service custom building and remodeling in St. Mary's County.
New Life Builders — Lexington Park-based, handling custom new homes and turn-key additions for St. Mary's County homeowners.
Brooke Built Homes — based in the Dunkirk and Huntingtown area of Calvert County, building single-family homes either on your lot or one of theirs, across Calvert, St. Mary's, and Charles County.
Matthew S. Keen Construction — a Lusby-based, family-owned contractor handling custom builds and major renovations in Calvert County.
Integrity Builders — based just north in Anne Arundel County, with an active presence building semi-custom and on-your-lot homes in Calvert and St. Mary's County. Charles County isn't currently part of its published service area.
How to Choose Between a Production Builder and a Custom Builder
If you already own land, a custom or build-on-your-lot builder is usually the more natural fit, since most production builders only build inside their own communities. If you don't have land yet, a production or semi-custom community can simplify things quite a bit.
A few practical differences are worth knowing before you start comparing quotes:
Timelines. Production communities often move faster because plans and permitting are already standardized. Custom builds, especially on rural or waterfront lots, can take longer due to well and septic approval, perc testing, or shoreline permitting.
Pricing structure. Production and semi-custom builders typically price by floor plan and lot, with a published menu of upgrades. Custom builders price more individually, based on your specific plan, lot, and finish choices.
Representation. You can, and should, bring your own real estate agent even when working directly with a builder's sales office. The person at that sales desk represents the builder, not you.
Warranties. Ask every builder, production or custom, exactly what warranty is included and what it actually covers. Coverage varies more than most people expect.
None of this makes one path better than the other. It just means the right fit depends on your land, your timeline, and how involved you want to be in the design decisions. If you're still working through the questions to ask before signing, my guide on new construction questions walks through it in more detail.
How This Plays Out Differently by County
St. Mary's County
St. Mary's County is home to several of the custom builders on this list, including St. Marie's Builders, W.M. Davis, Wood Construction, and New Life Builders, based out of Hollywood, Mechanicsville, and Lexington Park. Because so much of the county sits near NAS Patuxent River, a good share of new-construction buyers here are relocating or PCSing on a deadline, which makes builder communication and realistic timelines especially important. You'll also find production activity from D.R. Horton in the area, alongside larger rural lots further from the base and tighter lots or townhome product closer to Lexington Park and California.
Calvert County
Calvert County has the most builder activity of the three counties covered here. Marrick Homes, Quality Built Homes, Schaefer Homes, Southern Maryland Home Builders and Developers, Brooke Built Homes, and Matthew S. Keen Construction are all active in Calvert, and Integrity Builders' service area reaches here as well. Prince Frederick functions almost like a builder hub for the region. New construction buyers here tend to skew toward move-up buyers and those drawn to Calvert's waterfront-adjacent lifestyle, and inventory here is a mix of planned communities and smaller infill lots.
Charles County
Charles County is where you'll find the heaviest production-builder presence, with Lennar, Stanley Martin Homes, Ryan Homes, and D.R. Horton all active alongside local builders Wilkerson Homes, Litz Custom Homes, and Rainbow Construction, all based right in the county. Charles County's shorter commute into DC and Northern Virginia via Route 301 tends to pull new construction toward larger planned communities and townhome product closer to Waldorf and La Plata, with more custom builds on acreage the further out you go.
Common Misconceptions About Building New in Southern Maryland
"A custom builder is always more expensive than a production builder." Not necessarily. Land cost, lot size, and finish level usually matter more to your final price than which type of builder you choose.
"You don't need your own agent if you're buying directly from a builder." A builder's on-site representative works for the builder. Bringing your own agent typically costs you nothing extra and gives you someone looking out for your side of the deal.
"All builders offer the same warranty." They don't. Warranty length and exactly what's covered varies significantly between builders, so it's worth getting the specifics in writing before you sign anything.
"If a builder has been around a long time, everything they build is custom." Several long-established builders on this list actually offer a mix of production-style communities and true custom work. Ask which category your specific project falls into.
"Build on your lot works the same way everywhere." Rural lots often require well and septic approval, perc testing, and sometimes longer timelines than lots inside an established community. This varies by county and even by the specific parcel.
Frequently Asked Questions
How do I know if a builder is licensed in Maryland?
You can look up a builder's Maryland Home Improvement or contractor license through the Maryland Department of Labor's license search, and check with your county's permitting office for any builder-specific registration requirements before signing a contract.
Can I use my own real estate agent when buying from a builder?
Yes. In almost every case, you can bring your own agent to a builder's sales office at no extra cost to you, and your agent can review the contract and represent your interests throughout the process.
Is it cheaper to build on my own land or buy in a builder's community?
It depends on the lot, the location, and what you already own. Buying land and building separately can sometimes cost more upfront, but it also gives you more control over location and design, so it's worth comparing total costs across a few builders before deciding.
How long does it typically take to build a new home in Southern Maryland?
Timelines vary widely by builder and by lot. Production communities with standardized plans often move faster, while custom builds on rural or waterfront land can take longer due to permitting, perc testing, or septic approval. Ask any builder you're considering for their current, honest timeline rather than a general estimate.
Do any of these builders build near NAS Patuxent River?
Several builders on this list, including St. Marie's Builders, W.M. Davis, Wood Construction, and New Life Builders, are based in or near St. Mary's County and regularly work with buyers relocating for Pax River. Production builder D.R. Horton also has communities in the area.
What should I ask a builder before signing a contract?
Ask about their current warranty coverage, typical timeline from contract to closing, what's included versus what counts as an upgrade, and whether the price is locked in or subject to change. It's also worth asking to see a few homes they've already completed.
Should I get a home inspection on new construction?
Yes. New construction homes can still have issues, and an independent inspection at the pre-drywall stage, and again before closing, is a smart step no matter which builder you use.
Ready to Compare Your Options?
Whether you're leaning toward a production community or a custom build on land you already own, the builder you choose is only half the decision. Having someone in your corner who knows these builders, these counties, and how new construction contracts actually work matters just as much as the builder itself.
I work with buyers across St. Mary's, Calvert, and Charles County, plus the broader Maryland, D.C., and Virginia markets, and I'm always happy to walk through your specific situation with no pressure and no obligation. If you'd like a second set of eyes before you sign anything, my Southern Maryland buyer's guide is a good starting point, or you can reach out any time.
