Security Gates in Denver, CO
Custom-fabricated security gates, the controlled access point of your complete perimeter plan.
Get Free QuoteA security gate is the controlled access point that ties your entire perimeter together, and a poorly chosen or improperly installed gate undermines every fence panel, camera, and lock behind it. J.A's Privacy and Perimeter, led by owner Julian Lopez, designs, fabricates, and installs security gates for residential driveways, commercial properties, and multi-family sites across the metro. We work in wrought iron, steel, and aluminum, and we handle wiring, motor mounting, and permitting for hardwired automated systems all under one contract, so there's no gap between the fabricator, the installer, and the electrician.
Whether you need automatic driveway gates with keypad and smartphone access, a heavy-duty commercial slide gate rated for high-cycle daily use, or a pedestrian gate with RFID entry, the process starts with matching gate type to your property geometry, traffic volume, and local code requirements. Hardwired automated gates require a separate electrical permit; solar-powered systems generally don't. Julian Lopez handles site consultations personally and coordinates every step from design approval through post-install testing, so you're not handed off to a crew you've never met.

What Type of Gate Does Your Property Need?
Choosing the wrong gate type is the most expensive mistake in gate installation. Not the motor, not the access control system, not the material. Here's a straight breakdown of what belongs where.
Swing gates open inward or outward on hinged posts. They're the simplest mechanically, the most cost-effective to automate, and the right call for most residential driveways with 12 to 20 feet of clear arc space. Single-leaf swing gates suit openings up to about 16 feet; dual-leaf designs handle wider spans. If your driveway slopes steeply, inward swing clearance becomes a geometry problem, so a slide or folding gate is the cleaner answer.
Slide gates travel parallel to the fence line on a track or suspended cantilever rail. No arc clearance required. That makes them the default for tight lots, steep inclines, and commercial properties where vehicles stage close to the gate. The gate panel needs to be 1.5 to 2 times the opening width to allow full clearance when open.
Folding or bi-folding gates split into two panels that fold against each other as they open. They work where you need a slide-gate footprint without giving up the full linear stacking space a standard slide gate requires. Less common residentially, but the right call in commercial applications with tight side-clearance constraints.
Overhead rolling gates coil or stack above the opening on a barrel. Almost exclusively commercial or industrial: loading docks, parking structures, storage units. Their vertical clearance requirement and heavier operator weight class make them impractical for residential driveways.
For automatic driveway gates on residential properties, swing or slide configurations paired with a LiftMaster or DoorKing operator cover the vast majority of use cases. Getting this decision right at the start is the difference between a gate that lasts 20 years and one that fails in three.
How the Installation Process Works
A gate installation that holds up for 20-plus years isn't a one-day drop-and-drill job. Here's what it looks like when it's done correctly.
1. Site consultation and measurement. We walk the property with you, measure the opening width, evaluate the driveway grade, check fence line alignment, and identify the power source or confirm solar suitability. Owner Julian Lopez handles consultations personally, so you're not talking to a salesperson who hands the job off.
2. Design and material selection. You approve the gate style, material (wrought iron, steel, or aluminum), operator brand, and access control package before fabrication begins. Custom gates are built to your property's exact dimensions, not cut down from stock panels.
3. Permitting. For hardwired automated gates, we pull the electrical permit from the local Authority Having Jurisdiction. For HOA-governed communities, we prepare the Architectural Review Committee submittal with drawings and material specs. You don't navigate that paperwork yourself.
4. Post setting and foundation work. Gate posts carry far more lateral load than fence posts. We set them in full concrete footings sized to the gate's weight and the operator's push-pull force. Under-poured footings are the leading cause of gate sag and misalignment within the first two to three years. It's a shortcut we don't take.
5. Gate hanging or track installation. Hinges, pivot points, or cantilever rollers are set with gate plumb verified by level at every stage.
6. Operator mounting and wiring. The motor is mounted, limit switches are set, safety sensors are positioned per UL 325 standards, and wiring is run to the access control devices. For hardwired systems, the electrical rough-in is inspected before the circuit is energized.
7. Access control programming and testing. Keypads, remotes, RFID readers, intercoms, or smartphone integrations are configured and tested under load. We run the gate through a full open-close cycle sequence and verify entrapment protection zones are active before we consider the job complete.
Commercial vs. Residential Security Gates
The term 'security gate' describes two very different products depending on whether it goes on a home driveway or a commercial lot. Specifying the wrong product category is a shortcut that fails fast.
Residential gates are designed for low to moderate daily cycle counts, typically under 20 cycles per day. Operators are lighter-duty, the steel gauge in the gate frame is lighter, and access control is usually a keypad, remote fob, or smartphone app. Material choices lean toward aesthetics alongside function: wrought iron and powder-coated aluminum complement landscaping and architecture. Wood gates and fences work well together aesthetically on residential properties, and we fabricate wood gate panels to match cedar or redwood privacy fencing.
Commercial gates are engineered around cycle count, load, and liability. A commercial slide gate on a fleet yard or apartment complex may cycle 100 or more times per day. The operator must be rated for that load class. The gate frame is heavier-gauge steel or structural aluminum. Access control expands to RFID card readers, video intercoms, license plate recognition, and integration with property management software. ADA clearance requirements, fire department Knox Box provisions, and CPTED guidelines often become part of the specification.
Permitting also diverges. A residential hardwired gate install typically requires a standard electrical permit. A commercial installation may trigger a building permit for the structural foundation, an electrical permit for the power circuit, and in some municipalities a separate low-voltage permit for the access control wiring. J.A's Privacy and Perimeter scopes each install individually to confirm which permits are required before work begins. We don't guess and we don't skip.
What Drives Security Gate Installation Cost?
No two gate installs are the same. A price quoted over the phone without a site visit is a number to be suspicious of. Any contractor who'll quote you a firm number before seeing your driveway grade and measuring the opening is guessing. Here are the variables that actually drive cost up or down.
Gate type and opening width. A swing gate on a standard residential driveway costs significantly less to fabricate and install than a cantilever slide gate engineered for a wide commercial entrance. More steel, more hardware, more operator capacity, and each step up in scale adds material and labor.
Material grade. Wrought iron and heavy-gauge steel cost more than aluminum but carry higher load ratings and longer lifespans in high-cycle applications. Powder-coat finish quality also varies. A two-stage industrial powder coat outlasts a single-stage residential coat by years in Colorado's UV-intense climate and hard freeze-thaw cycles.
Automation and access control. A manual swing gate is the lowest-cost option. Add a LiftMaster or DoorKing operator, safety sensors, and a keypad, and the cost rises. Add a video intercom, RFID reader, or smart home integration, and it rises further. The right level of automation is determined by how many people need access and how often, not by what sounds impressive.
Site conditions. A flat concrete driveway with an existing power circuit nearby is the easiest possible site. A sloped gravel driveway with no power source within 50 feet requires more prep: grade leveling, conduit run, and potentially a solar operator system.
Permit fees and HOA review. Building and electrical permit fees are set by the municipality and are a pass-through cost. Any contractor who says permits aren't required for a hardwired install without pulling the relevant code should be asked to explain that in writing.

Permits, Codes, and HOA Requirements
Permitting is the question that separates gate contractors who know their work from those who don't, and it's the topic most competitor websites avoid entirely. We don't avoid it.
Electrical permits: Any hardwired automated gate in the metro requires an electrical permit pulled from the local Authority Having Jurisdiction, whether that's the City and County of Denver, Adams County, Arapahoe County, or another municipality. The permit covers the power circuit to the operator and entrapment protection devices required under UL 325. Solar-powered gate operators don't require an electrical permit because they don't connect to the building's electrical system.
Building permits: The gate foundation, specifically the post footings for large commercial or heavy custom gates, may trigger a building permit depending on footing depth and gate weight. For most standard residential swing gates, a building permit isn't required, but it's worth confirming with Denver Community Planning and Development before breaking ground. We check this at the consultation stage.
HOA Architectural Review: Properties in HOA-governed communities (Highlands, Lowry, Stapleton, and dozens of others across the metro have active Architectural Review Committees) require written ARC approval before installation. The submittal typically requires a drawing showing gate placement, dimensions, material, and finish color. Skipping this step can result in a removal order regardless of whether the gate was permitted by the city.
ADA clearance: Commercial gate installations adjacent to accessible routes must comply with ADA minimum clear width requirements. This affects gate panel configuration and hardware placement and should be engineered into the design phase, not retrofitted after installation.
J.A's Privacy and Perimeter prepares permit applications, HOA submittals, and code-compliance documentation as part of every install.
How to Evaluate a Gate Contractor Before You Hire
The listings for security gate contractors in the metro show a crowded field. Not every company on the first page is qualified to handle a permitted, automated gate installation from start to finish. Ask these questions before you sign anything.
Do they pull their own permits? A contractor who says permits aren't required for a hardwired installation, or who asks you to pull the permit yourself, is offloading liability onto you. Ask directly: 'Will you pull the electrical permit, and will the installation be inspected before the circuit is energized?' If they hesitate, that's your answer.
Do they fabricate the gate or source it from a catalog? Catalog gates come in standard increments. Your driveway opening probably isn't a standard increment. A contractor who fabricates to your exact dimensions eliminates the shimming, filler panels, and clearance gaps that result from forcing a stock panel into a custom opening.
What operator brands do they install? LiftMaster and DoorKing are industry-standard operators with established parts supply chains and warranty support. An operator brand you can't find parts for in three years is a long-term liability dressed up as a bargain today.
What's their post-install support structure? A gate stuck open or closed needs a contractor with a defined service response protocol, not a voicemail box. Ask directly: what's your response time for a gate failure, and what does a service call cost after the warranty period?
Are they scoped for the full install? Gate fabrication, motor mounting, and the electrical work covered by the pulled permit should all fall within the same contractor's scope. A subcontracted chain creates accountability gaps the moment something goes wrong.
J.A's Privacy and Perimeter handles fabrication, installation, operator mounting, and permit-covered electrical work under one contract. Owner Julian Lopez is on-site for consultations and reachable for follow-up directly, not routed through a call center.
Gates as Part of a Complete Perimeter Strategy
J.A's Privacy and Perimeter names the gate and the fence in the same breath for a reason: a gate installed without perimeter context is an access control point surrounded by gaps.
The gate is the weakest physical point in any perimeter by design, because it has to open. Everything connected to it determines how much that opening actually matters. A custom steel gate hung on 6-foot-center steel posts set in full concrete footings, connected to a privacy fence rated for Front Range wind loads, is a coordinated system. The same gate hung on an undersized post in a shallow footing is an expensive single point of failure.
Think about the perimeter in layers. The outer boundary (fence, wall, or natural barrier) defines the perimeter edge. The gate defines the controlled entry point. Access control on the gate determines who gets through. Lighting and camera positioning determine whether unauthorized access is visible and deterrable. Each layer reinforces the others, and each weakens without the rest.
For residential properties, the most effective perimeter strategy pairs a privacy fence on the rear and sides with a matching-style security gate at the driveway and a pedestrian gate at the side yard. Vinyl fence and gates can be specified together from the same material line for a clean, unified look that requires no painting. Materials, post sizes, and footings should be specified together, not as separate projects sourced from separate contractors on separate timelines.
For commercial properties, the perimeter design should account for vehicle turning radius at the gate, queuing depth before the access control device, emergency vehicle access, and integration with any existing surveillance or access management systems on the property.
If you're planning a full perimeter upgrade that includes automatic driveway gates alongside wood, vinyl, or chain link fencing, one conversation with J.A's Privacy and Perimeter covers the full scope, all coordinated under one contract for a unified perimeter plan.
Frequently Asked Questions
Do automated security gates require a separate electrical permit?
Hardwired automated gates require an electrical permit from the local Authority Having Jurisdiction, whether that's the City and County of Denver or the surrounding county. The permit covers the power circuit to the operator and the entrapment protection devices required under UL 325. Solar-powered gate systems don't connect to the building's electrical system and generally don't require an electrical permit. J.A's Privacy and Perimeter pulls the correct permits for every install, so you don't have to navigate that process yourself.
What's the difference between motorized gates for driveways and commercial gate systems?
Motorized gates for driveways on residential properties are typically rated for under 20 cycles per day and use lighter-duty operators like a standard LiftMaster residential unit. Commercial gate systems are engineered for 100 or more daily cycles, use heavier-gauge steel frames, and require commercial-grade operators rated for that load class. Running a residential operator on a high-traffic commercial entrance doesn't save money. It buys you an operator failure within a season or two. The right spec depends on your daily cycle count, not your budget preference.
What access controls work with an automated driveway gate?
Access control for automatic driveway gates ranges from keypads and remote fobs to RFID card readers, video intercoms, license plate recognition, and full smart home integration via platforms like myQ or Z-Wave. For most residential driveways, a keypad with rolling-code remote fobs covers the household. Multi-family and commercial properties typically benefit from RFID or video intercom systems that log entry events. J.A's Privacy and Perimeter sizes the access control package to your actual traffic volume and security requirements, not the most expensive option available.
What is the difference between a swing gate and a slide gate for a driveway?
A swing gate opens on hinges and requires clear arc space, typically equal to the gate width, in front of or behind the opening. It's simpler mechanically and generally less expensive for standard residential driveways with flat approaches. A slide gate travels parallel to the fence line and requires no arc clearance, making it the better choice for sloped driveways, tight lots, or commercial entrances where vehicles stage close to the gate. The right choice depends on your available space, driveway grade, and expected daily cycle count.
Does my HOA need to approve a security gate before installation?
In most HOA-governed communities, including Highlands, Lowry, Stapleton, and others with active Architectural Review Committees, written ARC approval is required before any gate or fence installation begins. The submittal typically requires a site drawing showing gate placement, dimensions, material, and color. Installing without ARC approval can result in a removal order even if the city's electrical and building permits are already in place. J.A's Privacy and Perimeter prepares HOA submittal packages as part of every residential gate install. This is included, not an add-on.
How long does a security gate installation take?
A standard residential automated gate installation, from consultation through post-install testing, typically takes one to two weeks from signed contract to completion. Custom fabrication for wrought iron or heavy-gauge steel gates adds time depending on design complexity. Commercial installations with multiple access control integrations and required inspections may take two to four weeks. Permit processing time, which varies by municipality, is the variable most likely to extend the schedule. We provide a realistic timeline at the consultation stage before any deposit is taken.
What maintenance does an automated security gate require?
Every six to twelve months: lubricate the hinge pins or slide gate rollers, inspect the gate frame for rust or paint failure, test the safety sensors per UL 325 requirements, and verify the operator's limit switch settings haven't drifted. Battery backup systems should be tested annually. Post-and-footing integrity should be visually checked after hard winters, because Front Range freeze-thaw cycles can shift footings set in under-poured concrete. Catching a minor alignment issue early prevents a stuck-gate failure at the worst possible time.
Can automatic driveway gates be added to an existing fence?
Yes, but the posts at the gate opening must be evaluated first. A gate operator exerts continuous push-pull force on the hinge or track posts every cycle, forces a standard fence post was never designed to handle. In most cases, adding a powered gate to an existing fence means replacing the adjacent posts with heavier-gauge steel gate posts set in deeper concrete footings. Hanging a motorized gate on original fence posts is a shortcut that results in leaning posts, misaligned panels, and premature operator failure within a few seasons. We won't do it that way.
What's the difference between solar-powered and hardwired automated gates?
Hardwired gates connect directly to your property's electrical system. They're more reliable in low-light conditions and better suited for high-cycle commercial applications, but they require an electrical permit from the local AHJ. Solar-powered operators charge a battery through a panel mounted on or near the gate, a strong choice for rural properties or sites where running conduit to the gate would be cost-prohibitive, and they don't require an electrical permit. In Colorado's climate, a properly sized solar panel handles the job through most of the year, though battery backup is essential for extended cloudy stretches in winter.
Are automatic driveway gates worth it for a residential property?
Honestly, it depends on how you use your driveway. If you're opening and closing a gate manually multiple times a day, automation pays for itself in convenience within the first year. If the gate is primarily decorative and opens twice a week, a manual gate is the more practical call. Where automation consistently earns its cost: properties with children or pets that need a reliably closed perimeter, households where multiple drivers need independent access, and driveways on busy streets where you don't want to get out of the car. We'll tell you straight at the consultation if automation makes sense for your situation.
