What Architectural Drawings Include: A Complete Guide for Homeowners
When you hire an architect, you will receive a set of drawings. Understanding what those drawings include, and why each sheet is needed, helps you review them meaningfully and communicate with your architect and contractor.
Sheet Types in a Typical Residential Drawing Set
Cover Sheet (G-001)
Project information, drawing list, code summary, and general notes. Tells the building department everything they need to categorize the permit application.
Site Plan (A-001)
Shows the property in plan view, lot lines, existing and proposed structures, setbacks, parking, utility connections, drainage, and topography. Required for every permit application.
Floor Plans (A-1xx)
The most recognizable drawing type. Shows rooms, walls, doors, windows, stairs, and dimensions viewed from above. One plan per floor level.
Exterior Elevations (A-2xx)
Flat views of each side of the building showing exterior materials, window and door heights, roof slopes, and overall building appearance.
Building Sections (A-3xx)
Cut-through views showing how the building is assembled vertically, floor-to-floor heights, ceiling heights, structural elements, and insulation layers.
Wall Sections and Details (A-4xx)
Large-scale details showing how specific assemblies are constructed: how the foundation meets the wall, how the roof edge is finished, how windows are flashed.
Interior Elevations (A-5xx)
Flat views of specific interior walls, typically kitchens, bathrooms, and built-in casework, showing cabinet layout, countertops, and tile patterns.
Structural Drawings (S-xxx)
Produced by the structural engineer: foundation plan, floor framing plan, roof framing plan, and structural details. Required for all projects with structural elements.
