Defendants appeal from a judgment ordering issuance of a peremptory writ of mandamus directing the defendant city inspector to issue plaintiff a building permit for erection of multiple dwellings on certain property owned by plaintiff in the city of Royal Oak and directing the defendant city, mayor and city commissioners to amend the city’s zoning ordinance by changing said property from a residence “A” classification, in which single residences only are permitted, to a residence “B” classification, permitting erection of multiple dwellings thereon.
The trial court’s action was predicated on a finding that the provisions of the ordinance classifying-plaintiff’s property bear no relation to public health, safety or general welfare, are unreasonable and therefore deprive plaintiff of property without due process of law in violation of the 14th amendment to the Constitution of the United States and Michigan Constitution 1908, art 2, § 16, citing Senefsky v. City of Huntington Woods, 307 Mich 728 (149 ALR 1433), and City of Pleasant Ridge v. Cooper, 267 Mich, 603. The court appears to have been moved largely by consideration of the fact that it did not appear in the proceeding’s of the city commission in connection with the adoption of the ordinance that “any discussion or consideration was given to the public health, safety, public morals or public welfare,” further that *422defendants did not prove any relation between those “factors”. and the said “classification,” and finally that, the testimony of certain city officials indicated that in certain respects, bnt not necessarily in all, public health and safety would be as adequately served in a multiple dwelling as in a single residence area.
Testimony for the' defense established that the property in question fronts on Yinsetta Boulevard, one of the best streets in Royal Oak, wide and divided by a beautiful, well-kept parkway, and that the area is one of the choicest and nicest residential districts in the city; that lots in the area are all restricted to single residences; that no violations of the zoning ordinances or restrictions have occurred and that all dwellings built in the area are single residences. In our view plaintiff did not establish by competent evidence that the ordinance’s classification of plaintiff’s property is unreasonable or bears no relation to public health, safety or the general welfare.
In the court’s opinion in Village of Euclid v. Ambler Realty Co., 272 US 365 (47 S Ct 114, 71 L ed 303, 54 ALR 1016), involving the validity of provisions of a city zoning ordinance excluding apartment houses from residential districts, may be found a cataloguing and consideration of the respects in which such ordinance provisions bear a relationship to public health, safety, morals or general welfare. Citing that case as authority, this Court in Austin v. Older, 283 Mich 667, said:
“The improvement of residential districts by the exclusion of nonconforming businesses has a reasonable relationship to the public health, welfare and safety.”
The burden was not on the defendants to establish the relationship, but upon the plaintiff to show the *423lack of it. Austin v. Older, supra;. People v. Scrafano, 307 Mich 655; Fass v. City of Highland, Park, 321 Mich 156. This burden plaintiff did not sustain. While the ordinance must stand the test of reasonableness, the presumption is in favor of its validity and courts may not invalidate ordinances unless the constitutional objections thereto are supported by competent evidence or appear on their face. Portage Township v. Full Salvation Union, 318 Mich 693. Invalidity does not appear on the face of the ordinance merely from its classification of certain property for use. for single residences only, nor are the constitutional objections thereto or claims of unreasonableness supported by evidence in the case. The trial court was, therefore, in error in requiring issuance of the building permit.
.In City of Pleasant Ridge v. Cooper, supra, we held unreasonable and confiscatory a classification of property as residential when the record disclosed that the area was unsuited for that purpose. Such is not the case before us. No more in point is the Senefsky Case, supra, in which we held a zoning ordinance which “prohibits the erection of houses having less than 1,300 square feet of usable floor area” possibly reasonable “under proper circumstances” but not so “under the circumstances disclosed by this record” because the testimony affirmatively established that houses of lesser floor area-equally met the requirements of public health, safety and welfare in the community and under the circumstances then and there before the court.
While it is within the province of the courts to pass upon the validity of statutes and ordinances, courts may not legislate nor .undertake to compel legislative bodies to do so one way or another. Attorney General, ex rel. Graves, v. Mayor and Common Council of City of Adrian, 164 Mich 143; School District of City of Pontiac v. City of Pontiac, 262 *424Mich 338; City of Jackson v. Commissioner of Revenue, 316 Mich 694. The court erred in seeking to compel the defendant mayor and city commission members to amend the ordinance.
Plaintiff contends that PA 1921, No 207, § 4, as amended (CL 1948, § 125.584 [Stat Ann 1949 Rev § 5.2934]), under authority of which the ordinance was adopted, is unconstitutional as constituting an unlawful delegation of legislative power and authority because it provides that amendments to the ordinance, if protested by owners of 20 per cent, or more of frontage of certain affected property, shall become effective only upon three-fourths vote of the municipal legislative body. Authorities cited by plaintiff relate to ordinances which provide that the right to use property for certain purposes shall depend upon the consent of individual neighboring property owners. Such cases have no bearing on the question of the power of the legislature, in conferring ordinance-making powers upon municipal legislative bodies, to require a three-fourths vote of such legislative body as a prerequisite to adoption of amendments to ordinances under certain circumstances. We believe such action well within the powers of the legislature and that it does not constitute a delegation of legislative power to private individuals. See, in this connection, discussion in People v. Collins, 3 Mich 343, McCall v. Calhoun Circuit Judge, 146 Mich 319, and cases therein cited.
Judgment reversed and writ quashed, with costs to defendants.
