Permit-Ready Structural Engineering for Illinois Projects

James Davis, PE provides licensed structural engineering for residential and light commercial permit sets throughout Illinois. Permit-ready drawings and calculations are prepared for Chicago, Springfield, Naperville, Peoria, and Rockford, plus other cities and counties statewide.

Chicago-area remodels, wall removals, decks, and additions are common. Confirm whether the project is under the Chicago Building Code or an IBC-adopting suburb before design begins.

Whether you need structural calculations, permit-ready framing and foundation drawings, or plan-check responses, JD Building Engineering delivers code-compliant documents ready for Illinois building-department submittal.

Illinois building codes

Building, civil, and structural code requirements

Illinois 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.

Building code

Illinois occupancy, residential, and accessibility provisions that typically govern the permit set JD Building Engineering’s structural sheets support.

Code / Standard Application
Illinois-adopted IBC or Chicago Building Code Downstate and suburban jurisdictions generally use IBC; the City of Chicago maintains its own building code
IRC or Chicago residential provisions One- and two-family dwellings per the adopting AHJ
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 building code

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
IDOT / MWRD / local stormwater Driveway permits and Metropolitan Water Reclamation District rules in Cook County
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

Structural building code

Chicago-area remodels, wall removals, decks, and additions are common. Confirm whether the project is under the Chicago Building Code or an IBC-adopting suburb before design begins.

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
