Kent Fences Fail at the Post, and the Ground Decides How Fast
A fence in Kent rarely wears out from the top down. The boards grey and the moss takes the north face, but the fence is still standing until the posts let go at ground level, and how soon that happens is mostly a question of what the post is sitting in. Kent is split by about four hundred feet of elevation, and the two kinds of ground it produces treat a buried post very differently.
East Hill and West Hill: glacial hardpan holds winter water at post depth
The hills on either side of the valley are Vashon glacial till, mapped by the USDA as the Alderwood series: a gravelly sandy loam over a cemented hardpan that starts roughly three feet down. The hardpan carries load well, which is good for a footing, but it barely drains. From November to March the rain that soaks through the top layer perches on that hardpan and moves sideways, so the bottom of a post set in a concrete collar is standing in water for months at a stretch. Cedar tolerates wet-and-dry cycles; it does not tolerate wet-for-five-months, and the rot starts exactly at the line where the concrete meets the soil.
The valley floor: alluvial silt and a water table close to the surface
Down in the Green River valley, around the older residential pockets north and south of downtown, the soil is river-laid silt rather than till. It is deep and soft, it drains slowly, and in a wet winter the water table can rise within a few feet of the surface. Posts here do not perch on hardpan; they sit in saturated silt, and unsleeved wood behaves accordingly. The valley is also where a fence is most likely to lean, because soft ground gives less lateral hold than a hillside footing.
Forty inches of rain, front-loaded into the dark half of the year
Kent averages just over forty inches of precipitation a year, with November through January the wettest stretch. The total matters less than the pattern: most of it arrives between October and March, when nothing dries between storms. A fence built for this climate keeps its wood out of ground contact, drains its footings, and puts its posts on something the water cannot reach. That is the difference between the twenty-year cedar fence and the eight-year one, and it is what a good Kent installer is selling when the quote comes in above the cheapest bid.

Kent's Rules Before the First Post Goes In
Permits: seven feet inside the city, six in the county
The City of Kent's permit page lists fences seven feet high or less among the projects that do not need a building permit. Unincorporated King County, which still covers pockets around Kent's edges, draws its line at six feet and requires anything taller to meet the zoning setbacks for the parcel. Covington, Auburn, Renton, and the other cities on the service-areas page each publish their own threshold. A permit exemption is not a zoning exemption: the fence still has to obey the height and placement rules for its zone, and a contractor who works in Kent regularly will know which set applies to your address.
Corner lots: the sight triangle
Kent City Code 15.08.130 says that on a corner lot in a residential district nothing may be built, placed, or planted so as to block vision between two and a half and ten feet above street grade inside the triangle formed by the two street lines and a line joining points twenty feet back from the corner. In practice that clips the corner off a solid fence: within that triangle the fence drops to about thirty inches, becomes open picket or chain link, or stops short. The city's engineering department can confirm the sight-distance requirement for a specific corner before the layout is set.
The property line and the neighbour
Washington's fence statute is chapter 16.60 RCW, and it sits in the title on animals and livestock. Its partition-fence section, RCW 16.60.020, makes a neighbour who later encloses their land using your boundary fence pay half its value, and RCW 16.60.030 lets an owner give notice and require the adjoining owner to build half. Those sections were written for pasture, and a Kent subdivision is not pasture: for a backyard privacy fence there is no state rule that automatically obliges the neighbour to split the cost. Cost-sharing between neighbours in Kent is a written agreement or nothing.
Signs a Kent Fence Is Past Repair
- Posts that move when pushed, or that snap off at grade when a rail is lifted. Rot at the soil line is the standard Kent failure.
- A lean that has already been propped once and has come back, usually on the valley floor or a downhill run on East Hill.
- Rails pulling their screws or nails out of the posts because the post wood behind the fastener has gone soft.
- Several failed posts in one run. They were set together in the same ground; the survivors are on the same schedule.
- Boards you can push a screwdriver into at the bottom edge, where splash and ground contact keep them wet.
- A gate that no longer latches no matter how many times the hinge side is shimmed, which means the gate post itself has shifted.
One broken panel after a windstorm is a repair. Three soft posts in a forty-foot run is a replacement waiting for a budget, and the money spent propping it in between is money the new fence never gets back.

Kent Fence Questions
How much does a fence cost in Kent, WA?
A 6-foot cedar privacy fence runs about $35 to $65 per linear foot installed, vinyl privacy about $40 to $75, and residential chain link about $15 to $40 depending on height and coating. A 150-foot backyard therefore lands between roughly $2,500 in plain chain link and $11,000 in vinyl, before gates and tear-out. The cost guide breaks each range down.
Do I need a permit to build a fence in Kent?
Inside city limits, Kent's permit page lists fences 7 feet high or less among the projects that need no building permit; unincorporated King County stops the exemption at 6 feet. The fence still has to follow zoning and the corner-lot sight-distance rule either way. More on the FAQ page.
Should I repair my fence or replace it?
Repair when the damage is local: a rotten post or two, a sagging gate, a panel the wind took. Replace when it is systemic: posts rotting through in several places, rails pulling free, a lean that returns after propping. The posts were all set the same day in the same ground, so once several have gone the rest are close behind. See repair and replacement.
How long does fence installation take in Kent?
Most residential jobs take two to four working days on site: tear-out, posts set and left to cure, then rails, boards or panels, and gates. Wet ground on East Hill or the valley floor can add a day, and a boundary survey, if you need one, happens before the crew is booked.
