- What are the restrictions?
- What work requires licensed contractors?
- Where can I find the full regulations?

Ask:
- Do you allow owner-builders?
- What's the permit process for owner-builders?
- Any additional requirements beyond state law?
- Can you recommend resources?
Step 3: Check Financing Options
Call local banks and credit unions:
- Do you offer owner-builder construction loans?
- What are your requirements?
- What's the rate differential vs. traditional construction loan?
- What documentation do you need?
Step 4: Talk to Insurance Agents
Ask about:
- Builder's risk insurance (covers during construction)

When Location Matters Most
Sometimes WHERE you build is as important as IF you build:
Consider building in owner-builder-friendly area even if it means:
- Longer commute
- Different school district
- Rural vs. suburban
The right location can save you:
- Thousands in permit fees
- Months of bureaucratic delays
- Stress from fighting restrictive regulations
- Legal headaches
Bottom Line
Before you buy land or commit to building:
- Verify your state allows owner-builders
- Understand the specific requirements
- Confirm you can get financing
- Check with local building department
- Price insurance requirements
- Talk to other local owner-builders
Don't assume because you own land, you can build on it yourself. State and local rules can prevent this.
