Enter your dimensions. We compute the exact materials, cut list, and permit checklist for your state.

Raised beds are not regulated structures. Watch HOA rules on front-yard placement.

State-level rules only — cities and HOAs frequently add stricter requirements. Always confirm with your local building department before you dig.

Using pressure-treated lumber rated for above-ground contact only. Buy ground-contact PT.
Filling with pure topsoil — it compacts. Blend 60% topsoil, 30% compost, 10% aeration.
Setting the bed on turf without cardboard underneath. Bermuda grass will come up through it.

Step 1
Confirm site and permit path
Locate property lines, call 811 for utility marking, and check whether your city/HOA needs approval before you break ground.
Step 2
Order materials
Use the shopping list from our planner. Confirm delivery vs pickup — bulk lumber and concrete are usually cheaper delivered.
Step 3
Lay out and prep the site
Batter boards, string lines, level the base. Getting this right saves days later.
Step 4
Frame the structure
Follow the cut list. Check for square with the 3-4-5 method every few pieces. Fasten with the right structural screws.
Step 5
Finish and inspect
Sand, stain/seal, and (if required) schedule your final inspection before backfilling or closing anything up.
