A backyard fire pit can transform your outdoor space into a cozy gathering spot for friends and family. Whether you’re roasting marshmallows or enjoying a quiet evening by the fire, a well-built fire pit adds charm and functionality to your backyard. This guide will walk you through the steps of planning, constructing, and maintaining your own fire pit.

Planning and Preparation

Choosing the Right Location

Selecting the perfect spot for your fire pit is crucial for safety and enjoyment:

  • Distance from Structures: Ensure the fire pit is at least 10-20 feet away from your house, fences, trees, and other structures.
  • Flat Ground: Choose a level area to ensure stability.
  • Wind Direction: Consider prevailing wind directions to prevent smoke from blowing into seating areas or your home.

Design and Materials

Decide on the shape, size, and materials for your fire pit:

  • Shape and Size: Common shapes include circular, square, and rectangular, with a typical diameter for a circular fire pit being 36-44 inches.
  • Materials: Use heat-resistant and durable materials such as stone, brick, or metal.
  • Style: Choose a design that complements your backyard aesthetics.

Safety Considerations

Prioritize safety when planning your fire pit:

  • Local Regulations: Check local building codes and fire regulations. Some areas may have restrictions on fire pit size or type.
  • Fireproof Base: Ensure the area around the fire pit is free of flammable materials like dry grass or leaves.
  • Emergency Plan: Have a fire extinguisher, water source, or sand nearby to quickly extinguish the fire if necessary.

Materials and Tools

Materials Needed

  • Paver stones or bricks for the fire pit wall
  • Gravel for drainage and base
  • Sand to level the base
  • Fire ring insert (optional, but helps contain the fire and protects the fire pit structure)
  • Adhesive or mortar to secure the stones or bricks (if needed)

Tools Required

  • Shovel for digging the base
  • Level to ensure a flat surface
  • Tamper for compacting the soil and gravel
  • Trowel for spreading adhesive or mortar
  • Measuring tape for accurate measurements
  • Gloves and safety glasses for protection while working

Building the Fire Pit

Step 1: Preparing the Site

  1. Mark the Area: Use a rope or garden hose to outline the fire pit’s shape on the ground.
  2. Dig the Base: Excavate the marked area to a depth of about 6-8 inches.
  3. Level the Ground: Ensure the bottom of the dug-out area is level.

Step 2: Laying the Foundation

  1. Add Gravel: Pour a 4-6 inch layer of gravel into the pit and tamp it down to create a solid base for drainage.
  2. Layer of Sand: Add a 1-2 inch layer of sand on top of the gravel and level it.

Step 3: Building the Fire Pit Wall

  1. First Layer of Stones: Place the first layer of stones or bricks around the perimeter of the pit, ensuring they are level and snug against each other.
  2. Subsequent Layers: Continue adding layers, staggering the joints for stability. Use adhesive or mortar between layers if desired.
  3. Fire Ring Insert: If using a fire ring insert, place it inside the stone structure as you build up the walls.

Step 4: Finishing Touches

  1. Capstones: If desired, add capstones to the top layer for a finished look.
  2. Inspect: Ensure all stones or bricks are secure and the structure is stable.
  3. Clean Up: Remove any excess dirt or debris from around the fire pit.

Maintenance and Safety Tips

  • Regular Cleaning: Remove ash and debris after each use to maintain airflow and prevent buildup.
  • Check for Damage: Periodically inspect the fire pit for cracks or loose stones and repair as needed.
  • Proper Fire Management: Use appropriate firewood and avoid burning trash or other non-wood materials.
  • Supervision: Never leave a fire unattended and ensure it’s completely extinguished before leaving the area.


How deep should a fire pit be?

A typical fire pit should be 6-8 inches deep to accommodate a solid base and allow for proper drainage.

Can I build a fire pit on a patio?

Yes, but ensure the patio material is heat-resistant and consider using a fire pit pad or heat shield to protect the surface.

Do I need a permit to build a fire pit?

Permit requirements vary by location. Check with your local building department or fire authority to determine if a permit is needed.

What type of stone is best for a fire pit?

Heat-resistant stones like lava rocks, fire-rated bricks, or paver stones are ideal for fire pit construction.

How do I prevent my fire pit from smoking too much?

Use seasoned hardwood, ensure proper airflow, and avoid burning green or wet wood to reduce smoke.

Building a fire pit in your backyard can enhance your outdoor living space and provide a cozy spot for gatherings. By following these steps and safety tips, you can create a durable and enjoyable fire pit for many seasons to come. Enjoy your new backyard feature!
