Within the districts established by this Ordinance or amendments that may later be adopted, there exist lots, structures and uses of land and structures which were lawful before this ordinance was passed or amended, but which would be prohibited, regulated or restricted under the terms of this ordinance or future amendment.

Subject to ARTICLE III, it is the intent of this ordinance to permit these nonconformities to continue until they are removed, but not to encourage their continuation. Such uses are declared by this ordinance to be incompatible with permitted uses in the district involved. It is further the intent of this ordinance that nonconformities 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.

A nonconforming use of a structure, a nonconforming use of land or water, or a nonconforming use of a structure and land in combination shall not be extended or enlarged after passage of this ordinance by attachment on a building or premises of additional signs intended to be seen from off the premises, or by the addition of other uses of a nature which would be prohibited generally in the district involved.

To avoid undue hardship, nothing in this ordinance shall be deemed to require a change in the plans, construction, or designated use of any building on which actual construction was lawfully begun prior to the effective date of adoption or amendment of this ordinance and upon which actual building construction has been diligently carried on. Actual construction is hereby defined to include the placing of construction materials in permanent position and fastened in a permanent manner, except that where demolition or removal of an existing building, such demolition or removal shall be deemed to be actual construction, provided that work shall be diligently carried on until completion of the building involved.

Effective on: 1/1/1901

Where, at the effective date of adoption or amendment of this ordinance, lawful use of land exists that is made no longer permissible under the regulations imposed by this ordinance as enacted or amended, such use may be continued, so long as it remains otherwise lawful, subject to the following provisions:

1. 19.2.1
   No such nonconforming use shall be enlarged or increased nor extended to occupy a greater area of land than was occupied at the effective date of adoption or amendment of this ordinance.
2. 19.2.2
   No such nonconforming use shall be moved in whole or in part to any other portion of the lot or parcel occupied by such use at the effective date of adoption or amendment of this ordinance.
3. 19.2.3
   If any such nonconforming use of land ceases for any reason for a period of more than thirty (30) days, any subsequent use of land shall conform to the regulations specified by this ordinance for the district in which such land is located.

Effective on: 1/1/1901

Where a lawful structure exists at the effective date of adoption or amendment of this ordinance that could not be built under the terms of this ordinance by reason of restrictions on area, lot coverage, height, yards, or other characteristics of the structure or its location on the lots, such structure may be continued so long as it remains otherwise lawful, subject to the following provisions:

1. 19.3.1
   No such structure may be enlarged or altered in a way which increases it nonconformity.
2. 19.3.2
   Should such structure be destroyed by any means to an extent of more than sixty percent (60%) of its replacement cost at time of destruction, it shall not be reconstructed except in conformity with the provisions of this ordinance.

Effective on: 1/1/1901

If a lawful use of a structure, or of structure and premises in combination exists at the effective date of adoption or amendment of this ordinance, that would not be allowed in the district under the terms of this ordinance, the lawful use may be continued so long as it remains otherwise lawful, subject to the following provisions:

(Code of Iowa, Sec. 414.1)

1. 19.4.1
   No existing structure devoted to a use not permitted by this ordinance in the district in which it is located shall be enlarged, extended, constructed, reconstructed, moved or structurally altered except in changing the use of the structure to a use permitted in the district in which it is located.
2. 19.4.2
   Any conforming use may be extended throughout any parts of a building which were manifestly arranged or designed for such use at the time of adoption or amendment of this ordinance, but no such use shall be extended to occupy any land outside such building.
3. 19.4.3
   If no structural alterations are made, any nonconforming use of a structure, or structure and premises in combination may be changed to another nonconforming use provided that the Board of Adjustment, either by general rule or by making findings in the specific cases, shall find that the proposed use is equally appropriate to the district than the existing nonconforming use. In permitting such change, the Board of Adjustment may require appropriate conditions and safeguards in accordance with the provisions of this ordinance.
4. 19.4.4
   Any structure or structure and land in combination, in or on which a nonconforming use is superseded by a permitted use, shall thereafter conform to the regulations for the district in which such structure is located and the nonconforming use may not thereafter be resumed.
5. 19.4.5
   When a nonconforming use of a structure, or structure and premises in combination is discontinued or abandoned for six (6) consecutive months, the structure thereafter, shall not be used except in conformity with the regulations of the district in which it is located.
6. 19.4.6
   Where nonconforming use status applies to a structure and premises in combination, removal or destruction of the structure shall eliminate the nonconforming status of the land. Destruction for the purpose of this subsection is defined as damaged to an extent of more than sixty percent (60%) of the replacement cost at the time of destruction.

Effective on: 1/1/1901

On any nonconforming structure or portion of a structure containing a nonconforming use, work may be done in any period of twelve (12) consecutive months on ordinary repairs, or on repair or replacement of nonbearing walls, fixtures, wiring, or plumbing, to an extent not exceeding ten percent (10%) of the current replacement cost of the nonconforming structure or nonconforming portion of the structure as the case may be, provided that the cubic content existing when it became nonconforming shall not be increased. If a nonconforming structure or portion of a structure containing a nonconforming use becomes physically unsafe or unlawful due to lack of repairs and maintenance, and is declared by any duly authorized official to be unsafe or unlawful by reason of physical condition, it shall not thereafter be restored, repaired, or rebuilt except in conformity with the regulations of the district in which it is located. Nothing in this ordinance shall be deemed to prevent the strengthening of or restoring to a safe condition of any building or part thereof declared to be unsafe by any official charged with protecting the public safety, upon order of such official.

Effective on: 1/1/1901

Any use permitted as a special exception in this ordinance which is lawfully existing at the date of adoption of this ordinance shall not be deemed a nonconforming use, but shall, without further action, be deemed a conforming use.

Effective on: 1/1/1901
