Before You Build, Understand the Building Permit Process
Planning a residential construction project involves more than
deciding what you want to build. Depending on your property,
project scope, and local regulations, you may need to investigate
zoning requirements, property setbacks, existing conditions,
construction drawings, permit applications, and inspections.
Understanding these steps before construction begins can help
homeowners organize their information, ask better questions,
and have more productive conversations with building departments,
contractors, designers, and other qualified professionals.
This illustrated homeowner guide provides a practical introduction
to residential building permits and the preparation of drawings
commonly associated with permit applications.
Residential Projects Covered in This Guide
Whether you are planning a small improvement or a larger
residential construction project, the guide introduces
common permitting considerations for:

Understand Residential Permit Drawings
Residential building permit applications commonly involve
drawings that communicate the property’s existing conditions
and proposed construction. The specific documents required
depend on the project and local building department.
The guide introduces illustrated examples of:
- Site plans: Property boundaries, building locations,
setbacks, and other site information. - Floor plans: Room layouts, dimensions,
walls, doors, windows, and proposed changes. - Exterior elevations: Building appearance,
heights, openings, and exterior improvements. - Building sections: Vertical construction
relationships and building components. - Construction details: Selected details
illustrating how building elements are represented.
These examples help homeowners become familiar with the
types of residential drawings they may encounter during
the permitting process.
