How to build a gate in New York
Single or double swing gate with anti-sag hardware. A gate that doesn't sag comes down to three things: heavy posts, a diagonal brace pointed the right way, and the right hinges. Get those and it lasts decades.

Permits & code in New York
Gates follow the same rules as fences — most jurisdictions cap swing-gate height at 6ft in back/side yards and 4ft in front. Corner-visibility triangles apply at driveways.
State-level rules only — cities and HOAs frequently add stricter requirements. Always confirm with your local building department before you dig.
What most people get wrong
- Diagonal brace pointing the wrong way. Low corner MUST be on the hinge side — flip it and the gate sags in a month.
- Hinges screwed into a picket instead of the frame stile. The screws pull out and the gate drops.
- Undersized posts. Gate posts take four times the load of line posts — go 6×6 and set them deep.
The 5-step gate plan
- Step 1Confirm site and permit pathLocate property lines, call 811 for utility marking, and check whether your city/HOA needs approval before you break ground.
- Step 2Order materialsUse the shopping list from our planner. Confirm delivery vs pickup — bulk lumber and concrete are usually cheaper delivered.
- Step 3Lay out and prep the siteBatter boards, string lines, level the base. Getting this right saves days later.
- Step 4Frame the structureFollow the cut list. Check for square with the 3-4-5 method every few pieces. Fasten with the right structural screws.
- Step 5Finish and inspectSand, stain/seal, and (if required) schedule your final inspection before backfilling or closing anything up.
