Red Flags When Researching Land

Verify before you buy land

The wrong parcel can quietly kill a build. A missing code, a failed perc test, or an HOA ban can derail the whole project after closing — confirm every item below before you sign.

Before buying property for owner-building, verify:

Building codes (or lack thereof) in that specific location
Minimum lot size and setback requirements
Septic suitability (if not on sewer)
Well depth and water availability (if not on municipal)
Flood zone designation
Wildfire hazard zone
Wetlands, critical areas, or environmental restrictions
HOA restrictions (may prohibit owner-building)
Road access standards
Utility availability and connection costs

Next Steps

Read your state guide thoroughly
Contact local building department to verify current requirements
Join local owner-builder groups (Facebook, forums, meetups)
Purchase or download building codes for your jurisdiction
Verify contractor licenses (for trades you'll hire)
Research land carefully before purchasing
Create detailed budget including all permit fees and special requirements
Develop realistic timeline accounting for your state's processes
