CSI vs NAHB Cost Codes
Before importing, it’s important to understand which system fits your projects best.
Construction Specifications Institute (CSI) Cost Codes – Best for commercial and large-scale projects.
They follow a detailed division structure (e.g., concrete, mechanical, finishes) and allow for granular cost tracking.National Association of Home Builders (NAHB) Cost Codes – Best for residential construction.
They are simpler and aligned with home-building workflows.
Import Cost Codes
Buildern provides a preloaded lists of cost codes that you can import directly into your account.
To import cost codes:
Navigate to Cost Codes from your account settings
Click the Import button in the upper-right corner
Select the option to import from the NAHB or CSI list
Confirm the import
After choosing to import from the needed list, Buildern takes you to a dedicated screen where all available cost code categories are neatly organized and ready for selection.
You will see a structured list of major cost code groups, each representing a different phase of construction.
Each category can be expanded to review the detailed cost codes inside, giving you full visibility into what will be imported.
Complete the Import
Once you review the categories click the Import button in the bottom-right corner. Buildern will then automatically add the selected cost codes to your account.
💡 Tip - If you're just getting started, it's recommended to import the full NAHB or CSI structure. You can always refine, rename, or reorganize the codes later based on your workflow.
Customize Imported Cost Codes
Once the NAHB cost codes are imported, your setup is not final yet - this is where you adapt the structure to match your workflow.
Buildern allows you to review and adjust each cost code, so it aligns with your internal naming conventions and project structure.
To edit a cost category:
Locate the category you want to update
Click the three-dot menu (⋯) on the right side of the category row
Select Edit
After clicking Edit, a configuration window will appear where you can modify the category details.
Here, you can update:
Title - Rename the category
Parent category - Assign it under another category (or keep it as top-level)
Code - Adjust the code range (e.g., 1000–1999)
Once your changes are complete click Save Changes to apply updates
ℹ️ Note - Make sure to save your changes before moving to another category. Any updates will be reflected across your estimates and reports.
