County Building Codes Explained: Beginner’s Guide for Landowners in 2025

by matt hammerly

Introduction

You’ve just bought a beautiful piece of land.

You want to build a cabin, park an RV, or set up your off-grid homestead.

But then you find out… you need permits.

What are county building codes?
How do they work?
And do they apply even in rural, “unrestricted” areas?

This beginner’s guide will walk you through everything you need to know to stay legal, safe, and stress-free as you develop your land in 2025.

📜 What Are County Building Codes?

County building codes are local rules and regulations that dictate:

  • What you can build

  • How you must build it

  • What safety standards must be followed

  • When permits are required

They’re enforced by the County Building Department, usually under the Planning or Development Services office.

Even in rural areas with no zoning, building codes may still apply—especially for:

  • Residences

  • Septic systems

  • Electrical work

  • Wells or plumbing

🧾 Common Building Code Requirements in 2025

Every county is different, but typical rules include:

Area Example Code
Minimum Square Footage Often 400–1000 sq. ft. for residences
Foundation Type Slab, pier, or approved skids for cabins
Septic System Perc test, approved plan, licensed installer
Electrical & Plumbing Permits + inspections required
Setbacks Must build a certain distance from roads/property lines

🏡 When You Must Get a Permit

Counties usually require a building permit for:

  • New home construction

  • Structural additions

  • Decks, garages, carports

  • Electrical wiring and solar installs

  • Septic tank installation

  • Wells and trenching

💡 Even building “off-grid” doesn’t exempt you if the county requires inspections.

✅ When You Might Not Need a Permit

Some counties allow you to build without a permit if:

  • The structure is under 200 sq. ft. (storage shed, outhouse, etc.)

  • It’s a non-dwelling structure (barn, tool shed)

  • You’re using the land temporarily (e.g., camping for a limited number of days)

Always call the building department and ask:

“What structures or uses are exempt from permitting in this county?”
