Washington State Building Code — IBC
JD Building Engineering
Washington licensed services
James Davis, PE provides licensed structural engineering for residential and light commercial permit sets throughout Washington. Permit-ready drawings and calculations are prepared for Seattle, Spokane, Tacoma, Bellevue, and Vancouver, plus other cities and counties statewide.
Puget Sound projects are seismic-driven. Spokane and eastern Washington add snow and frost. Washington energy-code coordination often affects framing and foundation details on the architectural set.
Whether you need structural calculations, permit-ready framing and foundation drawings, or plan-check responses, JD Building Engineering delivers code-compliant documents ready for Washington building-department submittal.
Washington State Building Code — IBC
ASCE 7 seismic design for Puget Sound; snow and ice east of the Cascades
NDS, AISC, ACI, and TMS design as the structure requires
Electronic seals where accepted by the authority having jurisdiction
Washington building codes
Washington jurisdictions adopt I-Codes or a state-specific code based on them. The tables below summarize the primary codes and referenced standards used for permit drawings and structural calculations. Local AHJ amendments still apply.
Washington occupancy, residential, and accessibility provisions that typically govern the permit set JD Building Engineering’s structural sheets support.
| Code / Standard | Application |
|---|---|
| Washington State Building Code — IBC | Commercial and multi-family construction with Washington amendments |
| Washington State Residential Code | One- and two-family dwellings with Washington seismic and energy amendments |
| International Fire Code (IFC) | Fire protection systems, hazardous materials, and fire-department access where adopted |
| IBC Chapter 11 / ANSI A117.1 / ADA | Accessibility for public accommodations and commercial buildings where they apply |
Civil deliverables, when the project and licence allow, include site and grading coordination, drainage, and retaining structures tied to the foundation design.
| Code / Standard | Application |
|---|---|
| IBC Chapter 18 — Soils and foundations | Site development, retaining walls, and foundation soils |
| WSDOT / Ecology stormwater | Driveway permits and Washington stormwater manuals (Western WA / Eastern WA) |
| Local grading ordinances | County/city grading permits, erosion control, and cut/fill limits |
| FEMA NFIP / local floodplain | Flood-zone compliance and elevation coordination where the site is mapped |
Puget Sound projects are seismic-driven. Spokane and eastern Washington add snow and frost. Washington energy-code coordination often affects framing and foundation details on the architectural set.
| Code / Standard | Application |
|---|---|
| IBC Chapter 16 | Structural design requirements — loads, materials, and systems |
| ASCE 7 | Minimum design loads: dead, live, wind, snow, rain, seismic, and flood |
| ACI 318 | Structural concrete design and detailing |
| AISC 360 | Structural steel buildings |
| NDS (AWC) | Wood construction — sawn lumber, glulam, shear walls, and diaphragms |
| TMS 402/602 | Masonry structures |
Structural services
James Davis personally manages the structural design, calculations, detailing, and drafting. Clients receive a coordinated permit-ready package rather than a review of drawings prepared by others.
Coverage
Licensed in 39 U.S. states and 5 Canadian jurisdictions. Remote structural engineering is available for qualifying projects.
Send the project address with your inquiry. JD Building Engineering will confirm sealing format and local AHJ requirements before work is scoped.
Questions
Yes. James Davis, PE is licensed in Washington and prepares permit-ready structural drawings and calculations for qualifying residential and light commercial projects. Sealing format (wet or digital) follows what the AHJ accepts.
Design follows Washington State Building Code — IBC, together with the referenced structural standards in the tables on this page and any city or county amendments that apply to the project address. Share the jurisdiction with your inquiry so the correct edition can be confirmed.
Yes. JD Building Engineering provides remote structural engineering for qualifying Washington projects using digital plan sets, email, and phone. On-site visits are not assumed and are confirmed only when a project requires them.
Typical work includes new homes, additions, remodels, ADUs, foundations, decks, retaining walls, and accessory structures. Light commercial structural work is considered when it fits the practice. The sealed work is structural engineering, with civil support where licensing allows.
