New Construction King County

At Royal Construction, we understand that every successful build begins long before the first nail is driven. That’s why we offer a comprehensive, step-by-step construction service suite tailored to King County’s unique regulations, landscapes, and design priorities. From the initial feasibility study to the final walkthrough, our team provides expert project management, precise craftsmanship, and local expertise to guide your project smoothly to completion.

Site Evaluation, Permitting & Pre-Construction Planning

Before construction begins, Royal Construction helps you make informed decisions through detailed assessments and expert navigation of local codes. In King County, where zoning laws and stormwater regulations are strict, this stage is crucial.

• Site Feasibility Studies: We evaluate key factors, including soil composition, slope stability, drainage patterns, easements, and existing infrastructure. Our local knowledge ensures that your lot complies with King County’s regulations for sensitive areas and critical lands.
• Permitting Assistance: Dealing with King County’s Department of Local Services (DLS) can be time-consuming. We handle your full permitting journey—from submitting plans and coordinating revisions to responding to municipal comments and securing final approval.
• Value Engineering: We work with architects and designers to streamline construction methods, reduce unnecessary costs, and optimize material choices—without compromising design intent or structural integrity.

Site Preparation & Land Development

A successful building project relies on a stable and well-prepared site. We provide end-to-end land development services that turn raw land into a construction-ready environment compliant with King County stormwater and grading codes.

• Clearing & Excavation: We remove trees, brush, outdated structures, and underground obstructions. Excavation is performed according to engineered plans with precision grading and slope control.
• Grading & Drainage: We contour the land to support foundation stability, manage surface water, and promote long-term property health. Drainage is installed to ensure compliance with King County’s Surface Water Design Manual.
• Erosion & Sediment Control: Using silt fencing, straw wattles, and hydroseeding, we protect surrounding areas and water resources, as required for construction in sensitive environmental zones.

Foundation & Structural Framing

Our crews follow strict engineering specifications and local building codes to ensure durable foundations and framing.

• Foundations (Slabs, Crawl Spaces, Stem Walls): We pour concrete foundations tailored to site conditions and structural type, ensuring optimal load distribution and effective water management.
• Structural Framing: Whether steel or wood, we erect framing systems that meet structural and fire codes. All framing is verified for alignment, squareness, and load-bearing capacity.
• Seismic & Wind Load Reinforcement: All materials and bracing techniques are selected to meet or exceed King County’s seismic zone requirements and local wind speed standards.

Utility Infrastructure Coordination

In both urban and rural construction, timely and compliant utility connections are essential. We coordinate with King County municipalities and utility providers to ensure seamless integration of core services.

• Power, Water, Sewer, and Gas Setup: We manage coordination with Puget Sound Energy, Seattle City Light, and the King County Wastewater Treatment Division to connect essential services.
• Telecom & Fiber Optic Installation: In a digitally connected world, we prepare your property for high-speed internet and communications infrastructure.
• Trenching, Metering, and Conduit Work: Our teams handle trenching, conduit installation, and meter setups, following strict guidelines to avoid costly rework and inspection failures.

Complete Buildout & Finishing

This is where your project truly comes to life. From the exterior envelope to the final interior finishes, Royal Construction emphasizes performance, beauty, and durability—always built to code and completed to your specifications.

• Building Envelope Construction: We install siding, insulation, roofing, and vapor barriers that comply with energy codes and improve building durability.
• Windows, Doors, and Trim: We utilize high-performance materials that strike a balance between aesthetics, energy efficiency, and safety.
• Interior Finishing: Every space is completed with skilled precision, from drywall, cabinetry, and flooring to custom millwork and tilework.
• Energy Code Compliance: We install HVAC, water heaters, lighting, and appliances that exceed WSEC (Washington State Energy Code) standards—helping you save on energy costs for years to come.

Final Inspection, Handover & Post-Construction Support

Our commitment doesn’t end when the building is done. We ensure that all final steps are completed and documented, leaving you with a space that’s ready to occupy—and built to last.

• Detailed Punch List Walkthroughs: We conduct thorough final reviews of every detail, from door alignment to paint touch-ups, ensuring that everything meets your exacting standards.
• Full Code Compliance Reviews: Our team ensures that all mechanical, electrical, and structural components meet King County’s final inspection requirements.
• Occupancy Certification & Closeout Documents: We handle the logistics of final permitting, occupancy approval, and turnover.
• Warranty & Maintenance Support: You’ll have ongoing access to our team for warranty service, seasonal maintenance advice, and support for future upgrades or renovations.
