The Complete Driveway Gate Planning Guide
Everything you need to know before you buy — gate type, opening width, automation, power, site prep, permits, and installation. Written by the team at System Fencing, building on 39 years of rural and estate gate experience in Ontario.
Planning a driveway gate for a rural, estate, or equine property involves more decisions than most buyers expect. Gate type, opening width, automation system, power source, site grade, permit requirements, and installation method all interact with each other. Make the wrong call on any one of them and you are retrofitting or replacing something expensive.
This guide walks through each decision in order. Use the section links to jump to what matters most to you right now, or read it through before you start talking to suppliers.
Step 1: Choose Your Gate Type
How it opens
Rotates inward or outward on hinges
Slides horizontally along fence line
Grade requirement
Relatively level across the arc
Level across the opening only
Clearance needed
Full arc of gate must be clear
Fence run of 1.5x opening width behind post
Winter performance
Excellent
Excellent (cantilever — no ground track)
Cycle speed
Moderate (15–30 sec typical)
Fast (10–20 sec typical for most operators)
Visual character
Traditional, substantial — most popular for estates
Modern, clean — works well on any property
Best for
Most rural and estate entrances with level grade
Sites with slope, limited clearance, or tight approaches, high snow loads
If you are not sure, send us your site photos and opening details and we will tell you which style works for your grade and clearance. Do not assume swing works until you have confirmed the arc clears the grade, level across the driveway.

Step 2: Measure Your Opening Correctly
The opening width is the distance between the inside faces of your posts, pillars, or planned post locations — measured at the driveway surface. This is the number we build your gate to.
Key sizing considerations
- Single swing gates: typically 10–14 ft for vehicle access, 4–6 ft for pedestrian
- Double swing gates: 14–30 ft total (7–15 ft per leaf). For wide estate entrances.
- Sliding gates: opening width up to 40 ft on cantilever systems. Rack space must be 1.5x the opening width along the fence line.
- Minimum clearance for regular vehicle access: 12 ft. RV or trailer clearance: 16–20 ft. Keep in mind to have your gate back up to 75’ from the edge of the road for trucks and trailers to drive straight through a gate.
- Do not measure from the outside of pillars or posts — measure inside face to inside face at the driveway surface level.
If pillars are not yet built, this is the time to establish the opening width with your gate and post spec confirmed. Post placement after the fact is expensive to change.

Step 3: Choose Your Automation System
Do you need automation?
If you are going to use this gate daily — yes. A manual gate on a 400 ft driveway in January is not practical or fun to get in and out of your car or truck. Automation is the default recommendation for any gate used more than a few times per week.
Operator selection: what matters
- Gate type: swing and sliding gates use different operator families entirely
- Gate weight: heavier aluminum gates require higher-rated operators. We calculate the weight from your spec.
- Daily cycle count: residential operators are rated for a certain number of cycles per day. High-use sites require commercial-rated operators.
- Power source: standard 120V or 240V power, or solar (see Step 4)
- Access method: remote only, keypad, intercom, video, app control, or a combination
The SystemPost™ difference
Optional automated gate packages from System Fencing can include the SystemPost™ — a gate post with all wiring pre-installed at our factory. Conduit for the operator, intercom, keypad, and loop detectors is pre-routed inside the post before it ships. Your electrician arrives to a finished connection point.
This matters most on rural and estate installations where the post is often a finished stone column, precast pillar, or timber post — field-wiring through these materials is slow and expensive. The SystemPost™ eliminates it.
Not sure which operator is right for your gate? We’ll spec it for you.
Step 4: Plan Your Power Source
Standard power (120V or 240V)
If you have electrical service within 300 ft of the gate, connecting to grid power is the straightforward choice. Your licensed electrician runs a circuit from the nearest panel to the gate. The SystemPost™ pre-routes the conduit inside the post — the electrican connects at control panel.
Solar power
When grid power is more than 300 ft from the gate, trenching a power line across a driveway or laneway can cost as much as or more than the gate itself. Solar automation eliminates that cost for entrances where the conditions are right. Double gates still will need a tie in between the two posts.
Solar works well when:
- The gate will cycle fewer than 10–20 times per day
- The panel location has reasonable south-facing sun exposure
- The operator selected is appropriate for solar duty (swing operators typically draw less per cycle than slide operators)
Optional solar package can includes the SystemPost™ configured for solar — the panel mount, battery housing, and all conduit are integrated at the factory.
Not sure if solar is right for your entrance? Tell us your distance to power and daily cycle estimate.
Step 5: Understand Your Site Preparation Requirements
The gate is only part of the installation. These site preparation items must be addressed before or at the time of installation:
Post footings
Gate posts carry significant load — especially on automated swing gates where the operator torque is absorbed by the hinge post. Footings must be sized for the gate weight and soil conditions. We provide post and footing specifications with every quote. Will need to be installed below the frost line.
Conduit trenching
If you want a double gate with full automation, you will need 2 conduits from your power source (house, barn) and your internet source. you will then need 2 conduits across the driveway one for power and one for low voltage, communication. Need a line to you pedestal that will hold you gate access system. Need a line for your free exit (to get out of the gate)
Driveway surface
For sliding gates, the post locations on both sides of the opening and the roller post foundation must be set before the gate is installed. For swing gates on gravel or dirt surfaces, confirm there are no high spots in the arc of the gate before the opening is established.
Safety devices
All automated gate installations include safety measures: photo eyes or burial loops on the closing edge to prevent the gate closing on a vehicle or person. This is particularly important for sliding gates. We include safety device recommendations in every quote.
Step 6: Permits and Approvals
Permit requirements for driveway gates vary by municipality in Ontario. The following is general guidance — always confirm with your local building department.
- In most rural Ontario municipalities, a freestanding driveway gate does not require a building permit if it meets height and setback limits
- Gates attached to a fence or wall may be governed by the fence permit requirements
- Properties in an HOA or planned community may have separate approval requirements for gate style, material, or height
- Some road entrance gates near county or provincial roads may require approval from the road authority
- Electrical permits are typically required for the automation system — your licensed electrician handles this
When in doubt, contact your local building department with the gate type, height, and setback from the road before purchasing.
Step 7: Plan Your Installation
Supply only vs. full installation
System Fencing offers both. Supply-only orders ship anywhere in Ontario and the US with full fabrication drawings. Our SystemPost™ makes supply-only installations simpler for your contractor because the electrical work is pre-done at the factory.
Full installation is available in our Ontario service area. We handle post setting, gate hanging, operator mounting, intercom and keypad installation, and commissioning. Your licensed electrician connects power to the SystemPost™.
Pre-construction documentation
For every installation — supply-only or full install — System Fencing provides pre-construction documentation: conduit layout, power requirements, post placement drawings, and footing specifications. This gets everyone on site working from the same plan.

Step 8: What to Have Ready When You Request a Quote
The more information you provide upfront, the more accurate and useful your quote will be. Here is what matters most:
- Site address or general location (so we know the region and can assess site-specific factors)
- Driveway opening width — measured inside face to inside face at surface level
- Gate type preference — swing or sliding, or let us assess from your photos
- Driveway surface type: paved, gravel, dirt
- Power availability: distance from the nearest electrical panel to the gate, and whether 120V or 240V is available
- Expected daily cycle count — approximately how many times the gate will open and close per day
- Photos: one wide shot from the road showing the full entrance, one from inside looking out, one showing the nearest power panel or source
- Access requirements: remote only, keypad, intercom, video, app, or combination

Gate Questions
A swing gate works if two conditions are met: there is adequate clearance for the gate arc to open without hitting a vehicle, wall, or structure, and the driveway grade across the opening allows the gate to swing without contacting the ground. Send us a photo from the approach and one from inside the property — we can assess both from the images.
A cantilever sliding gate requires approximately 1.5 times the opening width as rack space along the fence line behind the leading post. For a 14 ft opening, you need about 21 ft of fence run behind the post. The post on the far side of the opening also needs a clear run for the counter-balance tail.
The SystemPost™ is System Fencing’s pre-wired gate post. All conduit, wiring, and connection points for the operator, intercom, keypad, and loop detectors are integrated inside the post at our factory before it ships. Your licensed electrician connects power at the post — no field routing through finished columns or pillars.
The most important items are your opening width (inside face to inside face), gate type, driveway surface, distance from power to the gate, expected daily cycles, and 2–3 photos of the entrance from the road and from inside. The more detail you provide, the more precise and useful the quote.
Supply-only customers can use their own contractor for installation. The SystemPost™ makes this significantly easier because all electrical wiring is pre-done at the factory — your contractor sets the posts and hangs the gate, and your electrician connects power at the finished post. Self-installation of the operator and electrical components is not recommended and may void the operator warranty.
Cost varies significantly by gate type, opening width, material, operator, and whether you need supply-only or full installation. Entry-level automated swing gate packages start in the five-figure range; custom estate systems with stone pillars, video intercom, and full installation are considerably more. The most useful thing we can do is quote your specific project — generic ranges rarely reflect the actual cost for your site.
