Driveway Gate Permit Requirements
Permits are a pain. But skip them and you risk fines, removal, or voided insurance. Not worth it.
Most cities require a permit for automatic gates.
What you usually need:
- Drawing showing where the gate goes
- Gate specs (material, size, weight)
- Opener specs (safety rules)
- Electrical plan
- HOA approval (if you have one)
How long: 1-4 weeks. Historic or coastal areas may add 2-6 weeks.
Specs That Matter: Cantilever
Cantilever Gate At a Glance
| Min width | 10 ft |
| Max width | 60 ft |
| Space needed | Space beside fence for gate - 1.5× gate width (extra part balances it) |
| Best for | Any slope - gate floats above ground, Uneven ground, Gravel driveways |
| Opener type | Chain or gear drive |
Cantilever gates float above the ground. No track. They handle slopes and gravel that other gates cannot.
Cantilever Gate: What to Know
Best for: Uneven ground. Gravel. Steep slopes. Snow and ice. The gate floats. Ground does not matter. Best for ranch and rural properties.
⚠️ Watch out: The gate needs extra length. A 20-ft opening needs a 30-ft gate. The extra part balances it. Many people are surprised how much fence space it uses.
💡 Pro tip: Gravel driveway? Cantilever is your answer. No track on the ground. No gravel jams. No track to clean. Other gate types struggle with gravel.
Gate Type Comparison
Each gate type has trade-offs. Space, slope, and width requirements determine the best fit.
| Factor | Swing | Sliding | Cantilever | Bi-fold |
|---|---|---|---|---|
| Space needed | Full arc radius | Side track run | 1.5× width lateral | Minimal |
| Max width | 20 ft | 40 ft | 60 ft | 30 ft |
| Slope tolerance | Poor | Fair | Excellent | Poor |
| Typical speed | 12-18 sec | 8-14 sec | 8-14 sec | 6-10 sec |
| Maintenance | Low | Medium | Low-Medium | Medium |
What Installers Wish You Knew (Before You Sign)
Methodology note: These tips come from common real-world install patterns. Always double-check local code, utility clearances, and your driveway layout before you start.
💡 Cantilever Gate (Steel)
The rollers at the balance end take a lot of weight. Ask for heavy-duty rollers rated for 150% of your gate weight. Standard ones wear out fast.

What makes a project go well:
- Measure the site. Do not guess.
