Residential Builders

What Residential Builders does

Residential Builders, LLC is a privately held, Maryland-based custom modular home builder founded in 2005 by Paul Nalley Sr. and headquartered at 1331 Linden Avenue, Halethorpe, MD. The company designs and delivers turnkey modular homes to individual homebuyers across five Maryland counties (Baltimore County, North Anne Arundel, Carroll, Harford, and Howard). Its offerings span ranch, cape cod, and two-story floor plans, with customization of floorplans, colors, and finishes configured via an online Favorites System and visualized through Chief Architect-powered 3D virtual tours.

The core technology stack is modular/systems-built construction executed in partnership with Ritz-Craft Custom Homes, which manufactures homes in Pennsylvania-based climate-controlled facilities with assembly-line quality control, third-party inspections, and (for the modular portion) a 10-year structural warranty. Ritz-Craft delivers modules to sites where Residential Builders manages excavation, foundation, set/finish, and final certificate of occupancy. Standard packages include 2x6 exterior walls, R-21 wall/R-38 ceiling insulation, low-e glass, and optional geothermal HVAC, with Energy Star certification available.

The business is direct-to-consumer: homeowners schedule appointments at the Halethorpe design center to design their home with Paul Nalley Sr. and receive financing guidance. Revenue is generated by one-time home sales on a turnkey basis (homes priced 100% complete, ready to move in, with optional appliance packages). The firm employs 11-50 people, maintains BBB A+ accreditation, and is veteran-owned and family-operated. Pricing is quote-based and not publicly disclosed.

Broad incumbents

• Cavco Industries: Cavco Industries is a publicly traded broad incumbent in factory-built housing, including manufactured and modular homes. It is larger and more diversified than Residential Builders, but operates in adjacent product categories and competes for the modular/mobile home buyer segment.
• Clayton Homes: Clayton Homes is the largest U.S. producer of manufactured and modular homes and a Berkshire Hathaway subsidiary. It is a broad incumbent rather than a direct competitor in the custom niche, but defines pricing and financing benchmarks that affect Residential Builders' customer expectations.
• D.R. Horton: D.R. Horton is the largest U.S. homebuilder by volume and a broad incumbent in residential construction. While primarily a for-sale production builder, it competes for the same Maryland-area buyer pool and represents the primary alternative purchasing path for buyers Residential Builders targets.
• Champion Home Builders: Champion Homes is a publicly traded broad incumbent in factory-built housing (modular and manufactured homes). It is much larger and more diversified than Residential Builders but operates in the same product category and competes indirectly for buyer mindshare in the modular space.
• Lennar Corporation: Lennar is a top-tier national homebuilder with significant Maryland presence. It competes for the same end buyer in the Baltimore metro and broader Mid-Atlantic region, representing the 'site-built for-sale' alternative to Residential Builders' custom modular offering.

Direct peers

• Ritz-Craft Custom Homes: Ritz-Craft is Residential Builders' core manufacturing partner and a direct peer in the modular/systems-built housing space, producing homes since 1954. It is the upstream supplier and effectively an extension of Residential Builders' own production capability, making it the closest comparable for modular construction economics.
• Impressions Modular: Impressions Modular provides custom modular homes with similar design flexibility, energy efficiency focus, and online configuration tools. It is a smaller direct peer competing for the same type of custom home buyer that Residential Builders targets.
• Impresa Modular: Impresa Modular is a direct competitor in the custom modular home sales channel, offering turnkey modular home construction across multiple U.S. states. Highly comparable in business model (custom modular, direct-to-consumer, factory-built), serving as a useful benchmark for go-to-market and pricing.
• Express Modular: Express Modular is a custom modular home builder delivering turnkey projects similar to Residential Builders' model, with comparable customization options and energy-efficient construction focus. Operates across multiple states, making it a relevant direct peer in the same product category.

Regional players

• K. Hovnanian Homes: K. Hovnanian has a meaningful Mid-Atlantic / Mid-Atlantic-region presence and competes for similar suburban Maryland home buyers. While a production builder rather than a custom modular specialist, it is a relevant comparator on price points and buyer segmentation in the same geography.
