Radford Building Company is a Durham, North Carolina-based design-build firm founded by Jason Radford that specializes in accessory dwelling unit construction and residential renovation. The company holds an NC Unlimited Building License (number 83850) and operates across Durham and Chapel Hill, serving homeowners who want custom ADUs tailored to their site and lifestyle. Radford's approach is collaborative rather than assembly-line: the team works directly with clients through design, permitting, and construction phases, maintaining continuity in communication and decision-making throughout a project that typically spans 18 to 24 months from concept to move-in.
The firm builds multiple ADU configurations suited to different lot types and owner needs. The most common offering is a detached cottage, a freestanding structure in the backyard that operates independently from the primary residence. Detached ADUs in Durham are limited to 1,200 square feet under local zoning, but that size accommodates a spacious one-bedroom or two-bedroom layout depending on how the interior is planned. Another substantial portion of Radford's work involves garage conversions, transforming existing structures into living space at a lower cost than new construction. These conversions typically run $20,000 to $80,000, a fraction of the investment required for a new detached building. The company also builds in-law suites and guest suites, sometimes as attached additions to the primary home or as semi-detached configurations. This variety means homeowners with different constraints, an older property with a detached garage, a vacant backyard, a tight lot, or a specific layout preference, can find a workable path.
Pricing for a detached ADU in Durham ranges from approximately $90,000 on the low end to $300,000 or more depending on size, finishes, and site conditions. Radford's general construction costs run $300 to $500 per square foot for custom work, a range that reflects Durham's regional market and the firm's finish quality. This is higher than some prefab or standardized ADU builders but typical for design-build construction where every aspect is customized. The company does not publish a fixed-price menu; each project generates its own estimate after the team evaluates the lot, reviews the client's program (bedroom count, finishes, special features), and confirms local permitting requirements. Building permits in Durham are modest in cost (around $100 to $150 plus a plan review fee), a small component of the overall budget compared to construction itself.
The design-build process at Radford begins with detailed site evaluation and design development. The team meets with clients to understand the intended use (rental income, aging parent housing, guest accommodation, home office, etc.), preferred building type (detached, attached, or conversion), and aesthetic vision. They then develop architectural drawings and engineering plans suitable for city review and permitting. Once the team confirms that the design satisfies Durham building and zoning codes, they submit for permits and move into construction. Their website details a design-build methodology that treats each phase, site prep and foundation, framing, mechanical systems, finishes, as a structured sequence managed by the same team. This continuity reduces miscommunication and rework compared to projects where the designer, contractor, and subs operate independently.
Jason Radford, the company's founder, holds a bachelor's degree in Industrial Technology and Construction management and has worked in the building trade for more than two decades. The team includes Kenny, a project manager who coordinates with subs and inspectors, and supporting staff who manage design development and client communication. This structure resembles a boutique general contracting firm more than a high-volume production builder; clients work with named individuals rather than rotating sales representatives. Radford Building Company has earned Houzz service awards, and their project portfolio on the platform displays 20 completed jobs ranging from new homes and additions to kitchen renovations and ADU work. Houzz reviewers consistently rate them 5 out of 5 stars based on 14 detailed customer accounts. Google reviews are similarly strong at 5.0 stars with 25+ reviews. Customers often mention the team's professionalism, their attention to detail, and their willingness to refine designs before construction to avoid scope creep.
The company's portfolio includes a Yellow Warbler pool house, several Hillsborough and Durham new homes, renovations of existing kitchens and living spaces, and various ADU and addition projects. The photographs reveal a range of architectural styles and site conditions, suggesting the team can adapt their approach to different neighborhood contexts and owner preferences. One Houzz review highlighted that Radford revised plans multiple times before breaking ground, ensuring the final design truly matched the client's needs rather than pushing through to construction on a first draft. This design discipline is worth noting; many builders move quickly to break ground to start billing, but Radford's emphasis on refinement before construction can reduce expensive mid-project changes.
The company's project management approach emphasizes transparency and collaboration. From the initial site visit through final inspections, Radford keeps clients informed about budget, timeline, and any decisions that arise. Because the team manages the entire scope in-house rather than hiring separate designers and contractors, change orders and surprises are minimized; what is designed is what gets built. This integration also allows the firm to catch permitting issues early, during the design phase, rather than after construction has begun and changes become expensive. Durham's building department reviews ADU designs carefully, especially regarding lot coverage, setback distances from property lines, parking requirements, and utility placement. Radford's familiarity with these local code requirements, combined with years of working with Durham's specific inspectors, reduces the back-and-forth that often delays construction starts.
For Durham and Chapel Hill area homeowners who want a custom ADU without the hassle of hiring an architect and general contractor separately, Radford Building Company offers a single point of accountability. Their design-build model, local expertise (knowing Durham's permitting history and inspector preferences), and strong track record suggest a straightforward path from concept to occupancy. The main consideration is the timeline: 18 to 24 months from initial meeting to move-in is realistic for custom work, longer than prefabricated units or rapid-build operations but typical for design-build projects where quality and customization matter more than speed. For homeowners in the Research Triangle area of North Carolina seeking to add rental income, create multigenerational housing, or simply gain usable space on their property, Radford's established process and reputation make them a solid choice.
