Understanding the Approval Process for Your Custom Home

Before construction can begin, every custom home must meet local building requirements and receive the necessary permits. These approvals help ensure your home is built safely, complies with local building codes, and meets applicable zoning regulations. While the permitting process may seem overwhelming, working with an experienced design and build team can make it much more manageable. Understanding what to expect ahead of time allows you to plan your project with confidence and avoid unnecessary delays. At Hanson Design & Build, we help guide homeowners through every stage of the process, from initial planning to final approvals.

Why Building Permits Matter

Building permits are required to help ensure your new home is constructed according to established safety standards and local regulations. They provide oversight throughout construction and help verify that each stage of the project meets current building code requirements.


Obtaining the proper permits before construction begins also helps prevent costly issues, project delays, and potential legal complications in the future.

Choosing premium finishes or adding custom features will naturally increase the overall investment, while thoughtful planning helps maximize your budget.

Common Permits Required for a Custom Home

Permit requirements vary depending on the location, property, and scope of the project. A custom home may require several different approvals before construction begins.



Common permits and approvals include:

  • Building permits
  • Zoning approvals
  • Site development permits
  • Grading permits
  • Electrical permits
  • Plumbing permits
  • Mechanical permits
  • Septic or sewer approvals, when applicable
  • Driveway or right of way permits
  • Final occupancy approval

Your builder will determine which permits apply to your specific project and coordinate the necessary applications.

Understanding the Permit Process

Although every project is unique, the permitting process generally follows a series of steps before construction begins.

Project Planning

The process starts with developing your home design, confirming the property's zoning requirements, and preparing construction documents.

Plan Review

Local building officials review the submitted plans to ensure the proposed home complies with applicable building codes and regulations.

Permit Approval

Once the plans have been reviewed and approved, the required permits are issued, allowing construction to begin.

Construction Inspections

Throughout construction, inspectors visit the property at various stages to verify that work meets building code requirements before the next phase continues.

Final Inspection

After construction is complete, a final inspection is conducted to confirm the home meets all applicable requirements before occupancy.
