(a) 
Purpose. The provisions of this Article are intended to regulate the continuation, alteration, and eventual elimination of land uses, buildings, and structures that were lawfully established but that no longer conform to the use regulations or development standards of this Code due to subsequent changes in zoning, land use regulations, or other applicable laws.
The City recognizes that nonconforming situations may arise through no fault of the property owner; however, it is the policy of the City that such nonconformities are inconsistent with the long-term planning objectives of the General Plan and this Code and should be discouraged and eliminated over time, subject to reasonable limitations consistent with state law.
(b) 
Distinction between nonconforming uses and nonconforming structures. For purposes of this Article, nonconformities are categorized as follows:
(1) 
Nonconforming uses, which involve the nature or type of activity conducted on a site or within a structure that is not permitted by the zoning district in which it is located; and
(2) 
Nonconforming structures, which involve the physical characteristics, location, or dimensions of a building or structure that do not comply with applicable development standards, regardless of whether the use conducted therein is conforming or nonconforming.
Nonconforming uses and nonconforming structures are separate and independent concepts, and the regulations applicable to each are intended to operate independently except where expressly stated otherwise in this Article.
(c) 
Intent regarding nonconforming uses. Nonconforming uses are recognized as a temporary accommodation and not as a vested entitlement to continued operation indefinitely. It is the intent of this Article to:
(1) 
Allow the limited continuation of nonconforming uses under defined conditions;
(2) 
Prevent the expansion, intensification, enlargement, or re-establishment of nonconforming uses, except where expressly authorized by this Code;
(3) 
Encourage the conversion of nonconforming uses to conforming uses; and
(4) 
Provide for the eventual elimination of nonconforming uses through abandonment, discontinuance, amortization, redevelopment, or other lawful means.
(d) 
Intent regarding nonconforming structures. Nonconforming structures may be permitted to remain, subject to reasonable regulation, in order to avoid unnecessary hardship or constitutional infirmity. It is the intent of this Article to:
(1) 
Allow ordinary repair and maintenance of nonconforming structures;
(2) 
Regulate the enlargement, alteration, reconstruction, or replacement of nonconforming structures in a manner that reduces nonconformity where feasible; and
(3) 
Avoid conferring any right to perpetuate, expand, or intensify structural nonconformity beyond that which lawfully existed.
(e) 
No enlargement of rights. Nothing in this Article shall be construed to:
(1) 
Authorize the establishment of any new nonconforming use or structure;
(2) 
Create a vested right to expand, intensify, or continue a nonconforming use or structure except as expressly allowed herein; or
(3) 
Limit the City's authority to enforce this Code, abate nuisances, or exercise its police powers in a lawful manner consistent with state law.
(f) 
Applicability and interpretation. This Article shall be interpreted narrowly in favor of conformity with current zoning regulations. In the event of ambiguity, the interpretation that most closely advances the reduction of nonconformity and the elimination of nonconforming uses shall be favored, to the extent consistent with state law and constitutional protections.
(1343-CS, Rep&ReEn, 4/9/2026)
(a) 
Applicability. This section governs the continuation, change, enlargement, intensification, abandonment, and discontinuance of nonconforming uses whether of land or structures (or of both). The provisions of this section apply regardless of whether the structure in which the nonconforming use is located is conforming or nonconforming, except as expressly provided otherwise in this Code.
(b) 
Continuation of nonconforming uses. A nonconforming use that was lawfully established may be continued, subject to the limitations of this Article; however, such continuation is permitted only to the extent necessary to avoid undue hardship and shall not be construed as authorization to expand, intensify, or perpetuate the use indefinitely.
(c) 
Expansion or intensification prohibited. Except as expressly authorized by this Code:
(1) 
A nonconforming use shall not be enlarged, expanded, extended, or intensified, whether by increase in area devoted to the use, hours of operation, production or activity, occupancy, or any other means that results in a greater degree of nonconformity;
(2) 
A nonconforming use shall not be extended to occupy land, floor area, or portions of a site or structure not lawfully devoted to such use at the time it became nonconforming; and
(3) 
No action shall be taken that has the effect of prolonging or enhancing the economic life or operational scale of a nonconforming use.
(d) 
Change or substitution of nonconforming use.
(1) 
A nonconforming use may be changed to a conforming use, and once so changed, the nonconforming use shall not thereafter be resumed;
(2) 
A nonconforming use shall not be changed to another nonconforming use unless expressly authorized by this Code; and
(3) 
Any permitted change of use shall not increase the degree of nonconformity or create new nonconforming conditions.
(e) 
Abandonment or discontinuance. A nonconforming use shall be deemed abandoned and shall lose its legal nonconforming status when the use ceases or is discontinued for a continuous period of six months, regardless of intent to resume the use, or when replaced by a conforming use.
(f) 
Resumption prohibited. A nonconforming use that has been abandoned or discontinued shall not be resumed, re-established, or reinstated.
(g) 
Temporary suspension. A temporary cessation of a nonconforming use directly caused by events beyond the control of the property owner shall not constitute abandonment, provided the use is resumed within a reasonable time and in no event later than 12 months from the date of cessation.
(h) 
Effect of demolition or removal of structure. If a nonconforming use is conducted within or upon a structure, and that structure is demolished or removed, the nonconforming use shall not thereafter be resumed, except where reconstruction is expressly permitted under TMC § 9-2-306.
(1343-CS, Rep&ReEn, 4/9/2026)
(a) 
Applicability. This section governs buildings and structures that were lawfully established but that do not comply with current development standards of this Code.
(b) 
Continuation. A nonconforming structure may be continued subject to the limitations of this Article.
(c) 
Repair and maintenance. Ordinary repair, maintenance, and interior remodeling of a nonconforming structure may be performed, provided such work does not increase the degree of nonconformity. Repairs required to comply with health and safety codes shall be permitted.
(d) 
Enlargement or alteration.
(1) 
Minor enlargement or alteration not exceeding 1,000 square feet or 25% of existing gross floor area may be approved through a minor discretionary permit;
(2) 
Larger enlargements or alterations may be approved only through a conditional use permit and shall reduce or not increase the degree of nonconformity to the maximum extent feasible. Such enlargements and alterations must comply with the provisions for conditional use permits in Chapter 9-5 TMC.
(e) 
Demolition and reconstruction. Demolition and reconstruction of nonconforming structures shall be governed by TMC § 9-2-306.
(1343-CS, Rep&ReEn, 4/9/2026)
(a) 
Loss of nonconforming use status. A nonconforming use shall lose its legal nonconforming status upon abandonment or discontinuance pursuant to TMC § 9-2-302, conversion to a conforming use, replacement by another use, or demolition or removal of the structure in which it is conducted, except where reconstruction is expressly permitted under TMC § 9-2-306.
(b) 
Preservation of structural status. Loss of nonconforming use status shall not, by itself, result in loss of nonconforming structural status.
(c) 
Vacancy. Vacancy or non-occupancy shall not constitute loss of nonconforming structural status.
(d) 
Burden of proof. The burden of establishing the lawful existence and continuation of a nonconforming use or structure shall be upon the property owner.
(1343-CS, Rep&ReEn, 4/9/2026)
(a) 
Purpose. This section provides for the lawful discontinuance of nonconforming uses following a reasonable amortization period.
(b) 
Applicability. This section applies only to nonconforming uses and does not apply to nonconforming structures. Nothing in this section shall be construed to require amortization as a prerequisite to the termination of a nonconforming use that has been abandoned or discontinued pursuant to TMC §§ 9-2-302 and 9-2-304.
(c) 
Amortization authority. The City may require the discontinuance of a nonconforming use after a reasonable amortization period based on consideration of the nature of the use, its impacts, investment-backed expectations, and other relevant factors.
(d) 
Effect. Upon expiration of the amortization period, the nonconforming use shall be discontinued and shall not be resumed.
(e) 
Findings. Any requirement for discontinuance of a nonconforming use pursuant to this section shall be supported by written findings demonstrating that the amortization period provided is reasonable in light of the factors considered.
(1343-CS, Rep&ReEn, 4/9/2026)
(a) 
If at any time any nonconforming residential building is damaged or destroyed by fire, flood, explosion, wind, earthquake, war, riot, or other calamity or act of God, such building may be rebuilt within one (1) year to total floor area not exceeding that which such building originally contained and such building may continue as set forth in this article for nonconforming uses and buildings.
(b) 
Any nonconforming commercial or industrial building or structure damaged by fire, flood, explosion, wind, earthquake, war, riot, or other calamity or act of God to such an extent that repairs or replacements are required, the cost of which exceeds sixty (60%) percent of its current appraised value for tax purposes at the time of damage, exclusive of the foundation, shall not be restored or reconstructed and used as before such happening. If such building is less than sixty (60%) percent damaged above the foundations, it may be restored, reconstructed, or used as before; provided, however, the restoration or reconstruction shall be substantially completed within one (1) year of such happening.
(Formerly 9-2-406; 1207-CS, Rep&ReEn, 05/28/2015; 1237-CS, Amended, 12/28/2017)
Such repairs and maintenance work as required to keep a nonconforming building or structure in sound condition may be made; provided, however, no structural alterations shall be made except as are required by law or authorized by the Planning Commission as a conditional use pursuant to the provisions of Article 6 of Chapter 9-5 TMC (Conditional Use Permits and Variances). Except as otherwise provided in this article, the total structural repairs and alterations which may be made to a nonconforming building or structure shall not, during its life subsequent to the date of its becoming a nonconforming use, exceed fifty (50%) percent of its then appraised value for tax purposes unless such building or structure is changed to a conforming use.
(Formerly 9-2-407; 1207-CS, Rep&ReEn, 05/28/2015; 1237-CS, Amended, 12/28/2017)
The provisions of this article shall not require any change in the overall layout, plans, construction, size, or designated use of any development, building, or structure, or part thereof, where official approvals and required building permits have been granted before the effective date of the ordinance codified in this title, or of any amendment to the provision of this article, the construction of which building, conforming with such plans, shall have been started prior to the effective date of the ordinance codified in this title, and the completion thereof carried on in a normal manner within the subsequent six (6) month period and not discontinued until completion except for reasons beyond builder's control.
(Formerly 9-2-408; 1207-CS, Rep&ReEn, 05/28/2015; 1237-CS, Amended, 12/28/2017)
