This case involving floodplain and floodway building restrictions in Union County arises in the context of the development of a subdivision in an area between two streams. The County has had a Flood Damage Prevention Ordinance (hereinafter “flood ordinance”) since 1984, and amended it in 1993 and again in 2000. CGP, Inc. began considering development of a retirement community in Union County in the mid-1990s and discussed the project with the sole county commissioner in 1996. CGP purchased the land involved here *350 in 1997; got approval from the State Department of Health in May 1997; got a land disturbing activity permit and three building permits from the county that same month; got approval from the county of an erosion and sediment control plan; got approval from the Georgia Department of Natural Resources for the septic system; got final approval of the septic system from the county Board of Health; and got building permits for six additional houses in April 2000. When CGP sought more building permits in 2001, they were refused and CGP was told there would be no more permits issued until the subdivision was in compliance with the flood ordinance. CGP brought suit seeking a declaration of its rights and a writ of mandamus forcing the county to issue the desired building permits. After a hearing, the trial court denied mandamus, but declared CGP had a vested right to complete the subdivision without complying with the flood ordinance, and ordered the issuance of building permits on that basis. Union County appeals that judgment in the main appeal and CGP cross-appeals from the trial court’s denial of its claims regarding the validity of the flood ordinance.
1. It is the duty of this Court to consider the question of its jurisdiction in any case in which doubt arises that such jurisdiction exists.
Powell v. City, of Snellville,
*351
2. This Court held in
WMM Properties v. Cobb County,
It is apparent from reading the decision that all the bases enumerated in
WMM Properties
for the accrual of vested rights involve some species of estoppel. Union County points out, however, estoppel will not lie against a county government and vested rights do not arise from the issuance of illegal building permits. “Not even estoppel can legalize or vitalize that which the law declares unlawful and void.. . . [E]quitable estoppel will not apply so as to frustrate or contravene a governmental function of a governmental unit.”
Corey Outdoor Advertising v. Bd. of Zoning Adjustments &c. of Atlanta,
The issuance of a building permit results in a vested right only when the “permit has been legally obtained and is valid in every respect,” [cit.] and has been “validly issued.” [Cit.] Where a permit is issued by a governing body in violation of an ordinance, even under a mistake of fact, it is void, and its holder does not acquire any rights; even a substantial expenditure in reliance on a void permit does not raise an estoppel.
Matheson v. DeKalb County,
3. On cross-appeal, CGP asserts the trial court erred in rejecting its attacks on the validity of the flood ordinances. CGP contends the 1984 and 1993 ordinances are void because Union County failed to give its residents sufficient notice and opportunity to be heard when enacting the ordinances. Our consideration of this issue begins with the principle that “all reasonable presumptions favor the constitutionality of a legislative act, and the burden of showing to the contrary is on the attacking party. . . .”
Bohannon v. Duncan,
CGP also contends the 1994 and 2000 ordinances are invalid because their enactment did not comply with the Zoning Procedures Law (ZPL), OCGA § 36-66-1 et seq. The trial court rejected that attack on the basis of the holding in
City of Decatur v. DeKalb County,
*352 “Zoning” means the power of local governments to provide within their respective territorial boundaries for the zoning or districting of property for various uses and the prohibition of other or different uses within such zones or districts and for the regulation of development and the improvement of real estate within such zones or districts in accordance with the uses of property for which such zones or districts were established. (Emphasis supplied.) OCGA § 36-66-3 (3). Thus, “zoning ordinances” are those which “regulate by classifying property into separate districts. . . .”
In summary, we conclude the trial court did not err in rejecting CGP’s challenges to Union County’s flood ordinance, and the flood ordinance in place when CGP began development prevented the accrual of vested rights to development free of the restrictions imposed by the ordinance. Accordingly, we hold the trial court erred in holding CGP had obtained a vested right to complete its development free of the restrictions imposed by the flood ordinance and in ordering the county to issue without regard to the ordinances the building permits needed to complete the development.
Judgment reversed in Case No. S03A0669. Judgment affirmed in Case No. S03X0670.
