An honest split of what handy homeowners can do themselves, and the two or three things that decide whether a court lasts 25 years or cracks in two.
If you already have a sound concrete slab or an old sport court, a DIY route can work: modular tile kits snap together over a weekend, and portable nets plus taped or painted lines can turn a driveway into casual play for a few hundred to a few thousand dollars. For recreational hitting around, that's real value.
Grading to a true ~1% plane, drainage, base compaction, and a slab engineered for the soil, post-tensioned on clay, is heavy-equipment, permit-and-inspection work. A pad poured wrong cracks, ponds, and can't be fixed by any surface. This is 60% of a real court's cost and 90% of its lifespan.
Acrylic systems demand surface prep, moisture and temperature windows, and correct dilution/timing between coats. DIY acrylic jobs commonly peel, bubble, or wear in patches within a couple of seasons.
Thousand Oaks requires a Precise Plan of Design for home courts; LA applies house-yard setbacks to courts; HOAs require written architectural approval (Davis-Stirling). Skipping approvals risks removal, see local laws.
DIY on an existing slab: roughly $1,500–$9,000 in materials. DIY attempting pad + surface typically lands at 60–80% of a professional build once rental equipment, materials waste, and redone work are counted, with no warranty. Professional new builds here run $28,000–$58,000 with the pad engineered and warranted.
DIY the experiment (driveway, portable net, see if the household catches the bug). Hire out the permanent court, or at minimum the pad, and keep permits and HOA approvals clean. If budget is the barrier, a conversion of an existing court is usually the smarter middle path.
