7 N.C. App. 18
STATE of North Carolina
v.
Joseph MARTIN.
No. 696SC384.
Court of Appeals of North Carolina.
December 17, 1969.
*116 Atty. Gen. Robert Morgan by Staff Attorney Edward L. Eatman, Jr., Raleigh, for the State.
Jones, Jones & Jones, by Joseph J. Flythe, Ahoskie, for defendant appellant.
VAUGHN, Judge.
Defendant's assignment of error based on the failure of the court to allow his motion for nonsuit at the close of the evidence is overruled. Taking the evidence in the light most favorable to the State, as we are required to do, it was clearly sufficient to withstand motion for nonsuit.
Defendant contends that the ordinance which he is charged with violating is unconstitutional and assigns as error the denial of his motion to quash the warrant.
"A municipal ordinance is presumed to be valid, and the burden is upon the complaining party to show its invalidity or inapplicability. And a municipal ordinance promulgated in the exercise of the police power will not be declared unconstitutional unless it is clearly so, and every reasonable intendment will be made to sustain it." 5 Strong, N.C. Index 2d, Municipal Corporations, § 8, p. 626.
If a statute is susceptible of two interpretations, one constitutional and the other unconstitutional, the former will be adopted. State v. Dorsett, 3 N.C.App. 331, 164 S.E.2d 607.
The defendant specifically contends that the entire article of the zoning ordinance which deals with mobile homes, trailers and mobile home parks is unconstitutional because (1) "* * * there is an unconstitutional attempt to confer on the Ahoskie Building Inspector a naked arbitrary power to make a determination without standards of legislative guidance as to who and when and where and for what purpose a trailer home may be parked within the Town of Ahoskie * * *" and (2) the building inspector is authorized "* * * in his unbridled discretion, to determine whether additional temporary permits for the period of 120 days may be issued. * * *"
The section of the ordinance under which defendant was convicted makes it unlawful to store or park a mobile home in the town except in approved mobile home parks. Although defendant does not contend that he has attempted to establish an approved mobile home park and therefore that section is not relevant here, the ordinance clearly and concisely establishes the standards and procedures for obtaining approval of such park by the Town Council.
The sections which the defendant specifically attacks relate to duties of the building inspector with reference to nonconforming uses which were in existence at the time of the adoption of the ordinance. As is the case here, zoning ordinances generally make special provisions for land uses existing at the time of the enactment or effective at the time of their enactment or effective date. 58 Am.Jur., Zoning, § 146, p. 1021. The evidence here tends to *117 show that defendant moved his trailer into the town more than two years after the adoption of the ordinance. The sections he questions would not therefore apply to him.
The ordinance specifically provides that no maintenance permit may be issued for any mobile home park not in operation on the date of the ordinance. With reference to nonconforming parks in operation upon the effective date of the ordinance, the ordinance provides that "subject only to the provisions of this ordinance" the building inspector may issue temporary maintenance permits for renewal periods of 120 days. The ordinance is specific as to the conditions under which such a permit may be issued. This authority must also be read in the light of Article 9, Section 4 of the ordinance which in pertinent part provides:
"It is the intention of this ordinance that all questions arising in connection with the enforcement of the ordinance shall be presented first to the Building Inspector and that such questions shall be presented to the Board of Zoning Adjustment only on appeal from the Building Inspector; and that from the decision of the Board of Adjustment recourse shall be had to the courts as provided by law."
This assignment of error is overruled.
The defendant attempts to show by the cross-examination of plaintiff's witnesses that other trailers were parked in the town and that the ordinance had not been enforced against them. It is no defense to a criminal charge nor to one of this type that others have not been penalized or the law enforced as to them. Gastonia v. Parrish, 271 N.C. 527, 157 S.E.2d 154.
No Error.
