Sewer districts, septic rules and the $7,316
Kennett Township runs three sewer districts and charges $7,316 per equivalent dwelling unit to connect, which is a real number on a house or a lot that is not yet tied in. Outside those districts it is on-lot septic, and the township requires owners to file proof of pumping every three years. The Chester County Health Department permits on-lot systems and private wells and enforces Act 537, the state sewage law that also decides whether a vacant parcel can be built on at all.
For a buyer this means two inspections join the appraisal: a water test with the well’s yield in gallons per minute, and a septic report with the tank’s condition and the last pumping date. The sequence matters, because a failed system found in week four is a renegotiation and a failed system found in week one is a repair credit.
USDA, and how the answer actually gets found
This is the part worth being careful about. Parts of southern and western Chester County sit inside USDA-eligible areas, and the eligible ground starts around here. But USDA does not publish eligibility by town. It publishes a map, and the map is read address by address; two houses a street apart can get different answers, and the boundaries get redrawn.
So the honest sequence is: pick the house, run the exact address on USDA’s own eligibility map, and have the lender confirm it in writing before the offer goes in. If it comes back eligible and your household income fits the limit for this area, a USDA loan finances 100% of the purchase price with no down payment, with a guarantee fee up front and a small annual fee built into the payment. If it comes back ineligible, the same house is a conventional or FHA file and nothing else changes. Never plan a down payment around a town name.
1,967 houses in the borough, and a township around them
Kennett Square Borough covers 1.07 square miles and held 5,936 residents in 1,967 housing units at the 2020 census, arranged on a walkable grid of brick storefronts and twins under the State Street clock tower. Kennett Township is 15.48 square miles and 8,289 residents: the stone houses and Colonial Revival of Hamorton village, the Harlan Log House from about 1715, the Old Kennett Meetinghouse, and mushroom houses set back behind hedgerows. Kendal at Longwood and Crosslands, both continuing-care communities dating to the early 1970s, sit on Baltimore Pike and Street Road.
Driving it, and the first weekend of September
There is no rail here. Wilmington is about twelve miles and roughly twenty-three minutes for Amtrak or SEPTA, and the daily commute is U.S. 1. PennDOT’s $10.4 million widening and safety project through Kennett and East Marlborough, with a third lane where it fits, new sidewalks and five rebuilt signals, reached final striping on July 18, 2026.
The 41st Mushroom Festival takes over downtown September 12 and 13, 2026, at $5 a day, and Longwood’s Festival of Fountains runs through September 27, 2026. The region grows more than 500 million pounds of mushrooms a year, about half the national crop, and on a warm afternoon on Route 1 with the windows down you will know it. Locals stopped noticing years ago.
What sold, and what the bill looks like
Closings ran 137 in the Kennett Square area in July 2026 against 81 the previous July, a jump of more than half, at a $700,000 sold median and 61 days on market. Movoto, July 2026. That covers the whole postal area, so borough twins and township acreage are in the same number.
Kennett Consolidated School District set 36.2036 mills for 2026-27, up from 34.9942. Add the county’s 5.164 and the municipal line, and it still applies to 1996-era assessed values, not the price. A $700,000 sale implies an assessment near $214,000 at the county’s 30.6% common level ratio, which puts the school line around $7,748 a year before anything else.
Transfer tax is the standard 2%, or $14,000 on a $700,000 sale, customarily split with the seller. The county’s higher-rate municipalities are Malvern, Tredyffrin and the City of Coatesville, and none of them carries a Kennett address.
Sewer, where it exists, is billed by district: Longwood Crossing runs $140 a quarter and Ashford $541, which is a $1,600 difference a year between two township addresses. The borough bills its own water. None of those lines show up in a listing, and all of them belong in the escrow estimate.
