Fence Installation in Norwood, TN

On a small lot, the gates decide everything

A fence is a line on a plan. A gate is the part you operate several times a day for the next twenty years, and on the compact lots typical of Norwood there is not enough slack in the yard to fix a badly placed one later. Get the openings right and the fence disappears into daily life. Get them wrong and you are carrying trash bags through the house.

Four things drive gate planning, and they are worth working through before anyone measures for material.

The mower

Measure the widest thing that has to get into the back yard, then add clearance. A push mower needs less than people assume; a riding mower needs considerably more than a standard three-foot walk gate provides. A gate that is two inches too narrow is functionally the same as no gate at all.

Trash and recycling carts

Roll-out carts are wider than they look and they steer badly on grass. If the carts live behind the fence, the gate they come through wants to be on the side of the house that faces the curb, not the side with the tidier line. This is the detail homeowners most often want changed after the fact.

Vehicles and trailers

If anything with wheels needs to get into the back yard — a trailer, a utility vehicle, a truck for a future project — that requires a double gate, and a double gate requires a straight approach with room to swing. On a narrow lot the approach is usually the binding constraint, not the opening width. It is much cheaper to plan a ten- or twelve-foot double gate now than to cut one into a finished fence later.

The dog

A dog gate wants a self-closing hinge and a latch that works from both sides and cannot be nosed open. It also wants to be somewhere you will actually use it, because the gate people bypass is the gate that gets left open.

One more principle worth stating: more gates is not automatically better. Every gate is a break in the fence, a moving part and a potential sag point. Two well-placed gates beat four convenient ones.

Why gates sag, and why it is not the hinge

Gate sag is the most common call-back in this trade, and it is almost always a post problem rather than a hardware problem. The reason is load. A line post carries the fence in shear, sharing wind pressure with the posts either side of it. A gate post carries a cantilever: the full weight of the gate hanging out to one side, multiplied by the distance to the latch, working to lever the top of the post toward the opening every time the gate swings or sits open. That is a fundamentally different force, and a post sized for a fence line will not hold it.

So gate posts are bigger in section and set deeper and wider than line posts. On a double gate or a wide single, that difference is substantial, not nominal. When a gate starts dragging a year in, the hinge is usually fine — the post has rotated a degree or two in the ground, and no amount of adjustment at the hinge fixes a post that has moved. Re-hanging it on the same post buys a few months.

The ground here works against you in a specific way. Knox County subsoils commonly run 35 to 60 percent clay, which softens when saturated and stiffens when dry, and Knoxville averages about 52 inches of rain a year. A cantilevered load applied repeatedly to a post in wet clay is exactly the condition that produces rotation. Gravel at the base of the hole to drain the footing, concrete crowned above grade so water sheds away instead of pooling at the post, and an oversized footing at gate locations are what keep it plumb.

Depth follows the same logic as the rest of the fence. Knox County's adopted frost depth is 12 inches, but on a six-foot fence the governing load is wind rather than frost, so posts go well past that — and gate posts go past the line posts. Where bedrock is shallow, and it ranges from roughly 7 inches on shallow ridge soils to over 60 inches on deeper soils across the county, we adapt the footing rather than settle for a short hole at the one location that can least afford it.

Materials, and what a fence costs here

Gate count is one of the real drivers of where a job lands inside these ranges, along with height, material grade, terrain and how easily material reaches the line. On a narrow lot with no alley access, that last one adds up.

City rules and where the gate is allowed to swing

Norwood addresses inside the city limits fall under the City of Knoxville Zoning Ordinance. Article 10, section 10.3.L limits a privacy fence forward of the front building line to 42 inches. Side and rear yards are not capped at 42 inches under that provision, which is the usual reason a six-foot screening fence stops at the front building line and anything ahead of it is lower or open.

Whether your front building line sits where you think it does depends on your lot and setback. Confirm your address with the City of Knoxville, and confirm that your parcel is inside the city limits at all, since a property outside them is governed by Knox County rules instead.

Knox County section 3.20.04 restricts obstruction to vision in the sight triangle at intersections, and a solid panel counts as an obstruction. If your lot is on a corner, that constrains both fence height and, in practice, where a driveway gate can sensibly go.

Two more gate-specific points. A gate must not swing into a public sidewalk or right of way, so a street-facing gate on a shallow setback usually has to swing inward — worth knowing before you pick a location. And if a homeowners association covenant governs your property, it is a private agreement, frequently stricter than the zoning ordinance, and neither enforced nor waived by the city or county.

Licensing, and before we dig

Tennessee requires a contractor's license for work at $25,000 and above, and requires it before bidding or negotiating a price rather than before the first day on site. Knox County is one of only nine Tennessee counties that also require a separate Home Improvement license for residential work from $3,000 to just under $25,000 — Bradley, Davidson, Hamilton, Haywood, Knox, Marion, Robertson, Rutherford and Shelby. Holding a residential or commercial contractor's license exempts a contractor from that separate requirement.

Loudon County Fence, LLC holds Tennessee Unlimited Contractor License #54371. Check it at verify.tn.gov, and check anyone else you are considering while you are there. We have been installing fence since 1973, working out of 5482 Hwy 321 N in Lenoir City.

On materials, the lumber spec matters at gates most of all: pickets and rails are UC3B, posts are UC4A, rated for ground contact. They look identical the day they are installed and the category is printed on the end tag. LC Fence does not stock cedar and recommends ground-contact-rated pressure-treated pine. Before excavation, Tennessee 811 gets three working days' notice; the ticket is valid 15 days and the tolerance zone is at least four feet either side of a marked line. Private lines — irrigation, a buried pet fence, a feed to a garage or shed — are not covered by the free locate, and gate posts need the deepest holes on the job, so tell us what is down there.
