This is a zoning case. Prior to 1984, defendant Thayne Corbridge allowed about 20 head of cattle to graze on two abutting parcels of his land. The parcels are separated by a concrete drainage ditch. Cor-bridge would farm the western parcel, and once harvested, the cattle would graze on *608 both. Prior to 1984, the cattle were not fed hay or silage on the parcels, nor were they stored there through the winter. In 1984 Corbridge constructed a portable manger and a shed on the eastern property. Manure accumulated. He hauled hay to the cattle and kept them on the premises throughout the year. In essence Corbridge set up a feed lot. The trial court granted plaintiff Baxter’s request for an injunction requiring Corbridge to return to his pre-1984 method of farming on the basis that the use of the premises on a year round basis is an expansion or extension of a nonconforming use in violation of a Preston city zoning ordinance. We affirm.
I.
The City of Preston, effective February 15, 1979, adopted Zoning Ordinance No. 443, which established the following zones in the city: Residential, Transitional, Business, and Industrial. All of the property here involved falls within the “transitional” zone. The ordinance was intended to create a transitional buffer zone between agricultural areas and residential development. Conforming uses in the transitional zone are residential; all others are nonconforming. Chapter 1, § 6 of the ordinance provides that the “zoning pattern is not intended to eliminate agriculture uses within the city. It is, however, intended to discourage the establishment of new agricultural operations within the city limits.” Chapter 3 also provides:
Section 1 — Intent. It is the intent of this ordinance to permit nonconforming uses to continue until they are removed but not to encourage their survival. It is further the intent of this ordinance that nonconforming uses shall not be enlarged upon, expanded or extended nor be used as grounds for adding other structures or uses prohibited elsewhere in the same district.
As noted, Corbridge (and his family) own two abutting properties separated by a concrete drainage ditch. The western parcel is used for raising crops, principally corn and alfalfa. The eastern parcel was used, prior to 1984, solely for livestock grazing.
Corbridge acquired his properties in 1969. He grazed about 20 head of cattle on grass or crop residue, but prior to 1984 the cattle were never housed through the winter or fed silage on the property. In 1984 Corbridge constructed a portable manger, fed cattle, and kept livestock on the eastern parcel throughout the year. Manure accumulated.
Plaintiff Baxter tried unsuccessfully to get the City of Preston to enforce the ordinance against Corbridge. The city refused. Baxter thereafter brought suit against both the city and Corbridge. The action against the city was dismissed with prejudice after the city agreed that if Baxter was successful in the action against Cor-bridge, the city would enforce the ordinance.
The trial court held: that Corbridge’s historical use, and the use which he is entitled to continue under the ordinance, is limited to 20 head of cattle to forage on the eastern parcel in the summer; that after harvesting, the 20 cattle can forage on both the east and west parcels; that once snowfall makes grazing unfeasible, the livestock must be removed; and that Corbridge’s conduct in the use of the parcels on a year round basis (i.e., storing and feeding the cattle) is an “expansion or extension of a nonconforming use prohibited” by the ordinance. Finally, the trial court ordered Cor-bridge to remove the portable manger, holding corrals, accumulated manure, silage and feed on the eastern parcel. Cor-bridge has appealed from that determination.
II.
The trial court ruled that Cor-bridge’s use of his property constituted an unlawful nonconforming use. “Nonconforming use” means a use of land which lawfully existed prior to the enactment of a zoning ordinance and which is maintained after the effective date of the ordinance
*609
even though not in compliance with use restrictions. 6 Rohan,
Zoning and Land Use Controls
§ 41.01[1] (1978). As a general proposition, the due process clauses of the state and federal constitutions require that once a zoning ordinance is enacted, nonconforming uses be allowed to continue.
Glengary-Gamlin Protective Ass’n. v. Bird,
This “grandfather right,” as stated in
Bastian v. City of Twin Falls,
Some states, such as Massachusetts and Virginia, have devised “tests” for determining whether a nonconforming use has been extended or enlarged unlawfully.
E.g., City of Revere v. Rowe Contracting Co.,
Corbridge argues that the operation of a feedlot is an agricultural use just as grazing cattle is an agricultural use. Thus, so the argument goes, due process does not permit such a “flimsy distinction” between grazing and feeding cattle because the nature of the operation has remained unchanged: agriculture. Appellants’ Brief at 34.
The dispositive factor, however, is not into which general classification a use can be pigeonholed, but the character of the particular use. Otherwise, a property owner in an “industrial” zone manufacturing thumbtacks could thereafter produce automobiles solely on the basis that both are industrial endeavors. An analysis which focuses on the character of the particular use, not the general classification, is used elsewhere. See,
e.g., Village of Burr Ridge v. Elia,
As a general rule, the mere “intensification” of a nonconforming use does not render it unlawful.
Prince George’s County v. E.L. Gardner, Inc.,
In contrast to “intensification” are the concepts of “expansion and enlargement” of the nonconforming use. Expansion and enlargement of a nonconforming use contrary to a properly enacted- zoning ordinance is unlawful. For example, in
Cullen, supra,
the owner of a dairy farm increased his herd ten-fold, doubled the amount of land used, erected new buildings, and installed a new system of milk production. The court held that although mere increase in business is not
per se
proof of change of use, the expansion of the dairy farm was so great in the aggregate that it constituted an unlawful nonconforming use.
Cullen, supra,

First, the trial court found that as a result of the feedlot operation established by Corbridge manure on the property accumulated, thereby annoying neighboring property owners. As Professor Rathkopf states:
It will have been noted that in most of the cases involving changes which were held to be unlawful in theretofore permitted nonconforming uses, the subsequently adopted use had the potentiality for greater adverse impacts upon neighboring properties. The difference might lie in an increase in the traffic or noise generated, or in greater activity in and about the premises, or in other consequences of a more intensive use.

§ 51.06 at 78-79 (1988).

Second, the Preston ordinance specifically prohibits the construction of additional
structures
to further a nonconforming use.

Corbridge erected a portable manger and replaced a “loafing shed” on the property in 1984. Accordingly, the trial court did not err in ordering Corbridge to remove the new structures.
See Rathkopf, supra,
§ 51.07 at 99 (“The rule against enlargement or expansion also precludes the erection of new buildings or structures for utilization of the non-conforming use, either in replacement of the original buildings or in addition thereto.”);
Johnny Cake, Inc. v. Zoning Bd. of Appeals,
Finally, the character of the use has changed. Up until 1984, no cattle were kept on the property year-round. Further, whereas grazing cattle simply forage on plants growing on the property, under the feedlot arrangement the feed must be hauled to the cattle. In light of these differences, in addition to the accumulated' manure and new structures built on the property, the trial court did not err in con- *611 eluding that the expansion and enlargement in the character of Corbridge’s use were substantial and therefore in violation of Ordinance No. 443.
Whether the city of Preston’s zoning ordinance constitutes sound public policy is no concern of ours. Our sole inquiry is whether the ordinance, as applied to Cor-bridge’s property by the trial judge, is repugnant to the guarantees of due process. We hold that it is not and therefore affirm the judgment and order of the district court.
Affirmed. Costs on appeal to respondents; an award of claimed attorney fees is inappropriate.
Notes
. Judicial review of zoning cases is well-settled. Questions of fact supported by substantial competent evidence will not be disturbed on appeal.
