Moving here New Harmony
The two questions that decide every purchase in this valley
Five acres and a well, and which side of the line it sits on.
An incorporated town of 236 people covering six tenths of a square mile, sitting inside an unincorporated valley with 644 platted lots, four separate water companies and 294 parcels that were sold once and never built on. Two rulebooks, two lines on the map, and a septic percolation test that decides whether a lot is a lot.
Start here
One valley, two rulebooks, and the address decides which.
The first thing to understand about buying here is that New Harmony the town and New Harmony the valley are two different jurisdictions. The incorporated town covers about six tenths of a square mile and holds 236 people. The valley around it is unincorporated Washington County, and that is where almost all of the land and almost all of the platted lots actually are.
Inside the town limits you are under a land use ordinance the town adopted in January 2020, with four rural residential zones at half an acre, one acre, two acres and five acres, a hundred foot minimum lot width, and a cap of two and a half storeys or thirty five feet on any building. Outside the limits you are under county zoning, which works to an overall valley density of five acres per dwelling and will not go below two and a half acres per dwelling anywhere on septic.
Those are not small differences. They change what you can build, how many animals you can keep, whether a short term rental is even possible, and who you call when the road needs grading. And nothing in a listing photograph tells you which side of the town line a parcel is on.

The land
Six hundred lots, and one owner holding a third of the ground.
Washington County's land analysis for this valley counts 14,840 acres of private land. Of that, the incorporated town holds 280 acres, about 1.8 percent. The LDS Church holds 4,480 acres, about 30.1 percent. Roadways account for 350 acres, drainage channels and washes for 620, and Ash Creek Reservoir for 320. What is left as developable balance is 11,770 acres, roughly 79 percent of the private ground.
Against that sit ten recorded subdivisions carrying 644 platted lots on 3,934 acres: Blackridge Ranches at 233 lots on 1,470 acres, Kolob Ranches at 157 on 709, New Harmony Farms at 128 on 696, Harmony Heights at 74 on 240, and six smaller ones including a Fort Harmony subdivision of six lots near the old site. At the last full count, 350 of those lots had a dwelling on them and 294 were still empty, on a decade that produced 193 building permits.
Those numbers describe a specific kind of market. There is a large inventory of ground that was subdivided and sold long ago and never built on, and the constraint on building it is not planning permission in the abstract but water, septic feasibility and access on each individual parcel. A valley with 294 vacant recorded lots is not a valley with a shortage of paper.
Two hundred and ninety four lots in this valley have been sold at least once and have never had a house on them.
The first question
Which of four water systems serves this specific address.
There is no single water utility here. Four separate culinary systems serve the valley: the Town of New Harmony, Harmony Heights Water Company, Harmony Farms and Mountain Springs Water Company. Plenty of acreage parcels are served by none of them and run a private well instead. Which of those five answers applies to a given parcel is a question with a definite answer, and it is the first one to ask.
Irrigation is a completely separate system and it does not follow from the culinary answer. Many parcels carry irrigation shares through local companies, and those shares convey by the language in the deed rather than automatically, so a parcel with shares and an otherwise identical parcel without them are different purchases at different prices. The Town Ditch page covers where all of that water came from and where it is going now.
Waste is septic, permitted through the Southwest Utah Public Health Department, and it is the reason for the county's density floor: no development below two and a half acres per dwelling anywhere using septic, inside an overall valley density of five acres. On bare land, a percolation test is not a formality. It decides whether a parcel is a building lot or a view.
A New Harmony postal address does not mean a New Harmony town address. Harmony Heights is the clearest case: it carries New Harmony mailing addresses and sits entirely outside the town limits, under county zoning, on a private water company rather than a town system. Several other subdivisions in the valley are the same. Confirm jurisdiction from the parcel record rather than from the envelope.
The rules
What the town allows, and what the county allows.
Both sets are short, readable and specific, which is unusual. Here are the parts that actually change a decision.
| Inside the town limits | Out in the county | |
|---|---|---|
| Minimum lot | Half an acre, one, two or five, by zone | Five acres per dwelling overall, 2.5 minimum on septic |
| Building height | Two and a half storeys or 35 feet | County standards apply |
| Livestock | Half an acre minimum, three large animals on the first half acre | By county zone, generally agricultural |
| Short term rental | Conditional use, owner or manager must live on site | County rules apply |
| Roads | Town maintained inside the limits | County maintained as platted, paving by improvement district |
| Water | Town system where a connection exists | One of three private companies, or a well |
Both columns are summaries. Read the actual ordinance for a specific parcel, because both the town and the county amend theirs and the town restored one of its own zones as recently as the 2020 amendment.
The short term rental rule inside the town is the one that ends plans. A bed and breakfast, vacation rental or tourist home is a conditional use, reviewed and renewed every year, registered under the town's home business ordinance, and the owner or manager must reside on the premises. There is a cap of four guest rooms, a cap of two guests per bedroom or eight per residence, and a parking requirement of two spaces for the owner plus one per guest room. An absentee nightly rental is not a thing the town ordinance contemplates.
The livestock rules are more generous than people expect and more specific than they expect too. Half an acre is the minimum for large or medium animals, with up to three large animals on the first half acre and one more for each additional half acre, three medium animals counting as one large, and small animals allowed up to eight per quarter acre. Animals under six months do not count until they are weaned. If horses are the reason you are looking here, that arithmetic is the arithmetic.
One more that catches builders: a recreational coach or mobile home may only be occupied on a residential lot under a temporary conditional use permit, and only where a permanent dwelling is already under construction on a valid building permit. Living on the land in a trailer while you decide what to build is not available.
The strangest fact in the valley
There is no road from town to the national park entrance.
Kolob Canyons is ten minutes from New Harmony and there is no direct road to it. To get from the town to a park entrance you can see from the valley floor, you drive four and a half miles east to the freeway at exit 42, then south two exits to exit 40. That is not an accident of terrain. It is two separate landowner problems, both documented in the county's own general plan.
On the east side of the freeway the ground between the small subdivision at the New Harmony exit and the Kolob Canyons interchange belongs to the National Park Service. The county approached the park superintendent about opening a road through it many years ago and was told it would require an act of Congress. It never happened.
On the west side the LDS Church holds the bench as the majority landowner, and there was a period when the church was developing its property and the county was close to an agreement to open its road through. When the church decided to return the ground to livestock production and pause development, it no longer favoured opening a road through grazing land. The county says the roadway itself exists, is easily driven in a car, and is a scenic route, but that it is not prepared to condemn the property, fence the right of way and pave it.
The county also does not use property tax for road maintenance. Washington County funds county road maintenance from the state gasoline tax rather than from property taxes, and its long standing position is to maintain county roads in the condition they were in when the subdivision plat was recorded. If a subdivision was platted with unpaved roads, that is what the county maintains. Paving them is done through a special improvement district, spreading the cost over roughly ten years among the owners who want it.
What the valley says about itself
The county asked, and the answers are on the record.
When Washington County updated the general plan for this valley it ran a questionnaire, and the results are published in the plan itself. They are worth reading before buying, because they tell you what the neighbours expect the place to remain.
Asked why they lived here, 94.8 percent of respondents named being close to the mountains, 94.8 percent named the open space, and 94.8 percent named the quiet. Small town atmosphere came in at 87.1 percent, a safe community at 74.3, recreation at 66.6, and the opportunity to keep animals at 64.1. Homeowners made up 94.8 percent of respondents and average residency ran about ten years.
Asked whether the rural atmosphere should be preserved, 94.8 percent said yes. Asked whether farmland should be preserved, 97.4 percent said yes. Their suggested methods ran from the reasonable to the impossible, and the county said so in print, noting that it has no power to stop anyone selling agricultural land and does not enforce private covenants. Road conditions drew the strongest concern of anything asked, with 46.2 percent putting it at the top of the scale.
The highest rated services were drinking water quality, garbage collection and the postal service, with 59.2 percent giving the water full marks. That is worth setting beside the constraint: people here are not unhappy with the water they have. There is simply not much more of it available.
One suggestion in the plan's own summary is worth quoting for its honesty about the valley's position: asked where commercial development should go, one respondent proposed Enterprise, Central or Veyo. Another set of write in comments asked for the roadways to be connected, for two ways in and out of the valley, and for the old highway by the reservoir to be maintained. Those are still the live questions.
The practical year
Half an hour north, forty five minutes south, and real winter in between.
There is no school, no grocery store, no fuel station and no restaurant inside the town limits, and that is the trade the valley asks you to make. What sits either side of it is unusually good: Cedar City is about 22 miles and half an hour north with a university, a hospital with a 24 hour emergency department, a regional airport and ordinary shopping. St. George is about 40 miles and forty five minutes south with the regional hospital, a bigger airport and everything else. Residents pick a direction by the errand.
What the town does have is a Washington County Library branch at 34 South 2900 East, a fire station where the council meets on the first Wednesday of the month and the planning commission on the fourth, a cemetery that keeps its own directory on the shed, a park beside the fire station with playground equipment, horseshoe pits and a baseball backstop, and a 40 acre nature park on the western edge. For a town of 236 that is a lot of civic ground.
The climate is the other thing to plan for. Published normals put average annual snowfall at 37.2 inches and average precipitation at 17.59 inches, with a record high of 104 degrees in July and a record low of 20 below in February. That is a mountain specification for a house, a set of tyres and a heating plan, and it is not the specification anybody uses in St. George. Heating is propane rather than piped gas, and the electric provider varies by parcel and should be confirmed at the address.
Parcels against the forest boundary sit in the wildland urban interface. The Forsyth Fire burned over the ridge in Pine Valley in June 2025, took fourteen homes and about 15,675 acres, and closed the Pine Valley Recreation Area for at least the whole 2026 season. New Harmony sits against the same national forest on the eastern side of the same range. Defensible space, access for a fire engine, roof and vent specification, and insurance availability are all real questions on any parcel near the trees, and they are questions to ask before an offer rather than after.
The other line
Closer to Cedar City, and firmly in Washington County.
New Harmony is 22 miles from Cedar City and 40 from St. George, and it is in Washington County. That combination surprises almost everybody, and it is not a trivia point: the county assignment sets the school district your children are bussed into, the property tax area your bill is calculated in, and the county component of the sales tax you pay. Some acreage out in the wider valley sits near the line, so the county is a per parcel question rather than a town wide one.
Residents have raised the idea of switching. The county's own plan addresses it directly and explains the mechanics: any move to join Iron County would need contact with legislators from both counties and a bill through the State Legislature approved by the Governor, with the commissioners of both counties in agreement before it would gain any traction. The county states that it neither promotes nor opposes such changes and would support whatever the valley decided.
The same section covers incorporation, and the county's position is that the form of government closest to the people is the best one. It has floated annexing valley subdivisions into the town, or creating a second town under another name, and neither has happened. For now the valley remains what it is: an incorporated town of 236 people surrounded by an unincorporated valley with several times that many lots in it.

Buying here, answered.
It is a genuine acreage market, and the honest answer is that it depends entirely on the parcel rather than on the town. What decides value here is which of four culinary water systems serves the address or whether it is a well, which irrigation company any shares are in and whether the deed conveys them, how the septic percolates on the acreage available, and whether the parcel sits inside the town limits or out in unincorporated county. Two neighbouring parcels can answer those questions completely differently.
There is no single answer, and that is the point. A parcel inside the incorporated town falls into one of four rural residential zones, the smallest of which is half an acre and the largest five, each needing at least a hundred feet of frontage. A parcel outside the town falls under county rules, where septic sets the floor at two and a half acres per dwelling and the target across the whole valley is five. So the honest answer to the question is another question: is this address in the town or in the county?
Yes, and the town ordinance is specific about it. Half an acre is the minimum for keeping large or medium animals long term, with up to three large animals permitted on the first half acre and one more for each additional half acre. Three medium animals such as sheep, goats or pigs count as one large animal, small animals such as poultry and rabbits are allowed up to eight per quarter acre, and animals under six months do not count until weaned.
Only with the owner or a manager living on the premises. Inside the town limits a bed and breakfast, vacation rental or tourist home is a conditional use reviewed and renewed every year and registered under the town's home business ordinance, with a requirement that the owner or manager reside on site, a cap of four guest rooms, a cap of two guests per bedroom or eight per residence, and parking of two spaces for the owner plus one per guest room. An absentee nightly rental is not contemplated by the ordinance.
More than the population suggests. Washington County's records for the valley count ten recorded subdivisions carrying 644 platted lots across 3,934 acres, and at the last full count 350 of those lots had a dwelling on them while 294 were still vacant, on a decade that produced 193 building permits. The constraint on building the rest is water, septic feasibility and access on each individual parcel rather than any shortage of platted ground.
No. Expect septic rather than municipal sewer, permitted through the Southwest Utah Public Health Department, and expect a large minimum lot size per system: the county will not go below two and a half acres per dwelling unit anywhere on septic, inside an overall valley density of five acres. On a resale, get the tank inspected. On bare land, treat the percolation test as the thing that decides whether the parcel is buildable at all.
Because of two separate landowners, both documented in the county's general plan. The ground between the subdivision at the New Harmony freeway exit and the Kolob Canyons interchange belongs to the National Park Service, and when the county asked about opening a road across it years ago it was told that would take an act of Congress. On the west side of the freeway the LDS Church holds the bench and stopped favouring an open road when it returned the ground to livestock production.
Genuine. Published normals put average annual snowfall at 37.2 inches with a record low of 20 below zero recorded in February, at an elevation of about 5,300 feet. That means winter driving on SR-144 and the freeway stretch, a house built and heated for real cold, and propane rather than piped natural gas. It also means the summers run around eighty rather than a hundred and ten, which is the trade most people are actually buying.
It is a live conversation and a difficult mechanism. Washington County's own plan explains what it would take: contact with legislators from both counties, a bill through the State Legislature, the Governor's approval, and agreement from the commissioners of both counties before it would gain traction. The county states that it neither promotes nor opposes such a change. For now the county assignment sets the school district, the tax area and the county sales tax on every parcel here.
Acreage here is a homework problem before it is a purchase.
Four water companies, two rulebooks, a county line that runs near the valley, and a percolation test that decides whether a lot is a lot. I run all of it down on every acreage deal in this valley, and it is a great deal cheaper to do before an offer than after.
