Strаtbucker Children’s Trust (Stratbucker) appeals the Nebraska Court of Appeals’ decision that partially affirmed and partially reversed the district court’s rulings on the extension of a zoning waiver. Stratbucker contests the appellate court’s holdings that (1) the district court did not abuse its discretion by failing to extend Stratbucker’s zoning waiver for an indеfinite period; and (2) the district court improperly ordered appellant Omaha Zoning Board of Appeals (the board) *70 to reissue several revoked permits to Stratbucker. We affirm the judgment of the Court of Appeals in part, and in part reverse and remand.
On August 25, 1988, the board granted Stratbucker a conditional zoning waiver that allowed Stratbucker to operate a farmer’s market in an otherwise residential area of Omaha. The board conditioned the waiver on compliance with several requirements, including specified operating hours, limits on sign dimensions, compliance with the terms of an agreement with Omaha Planning Director S.P. Benson, and that “this waiver be conditioned on a one year review basis.”
On August 24, 1989, the board refused to continue the conditional waiver. Stratbucker appealed to the Douglas County District Court, which found in its July 16, 1990, order that the board had failed to give Stratbucker a fair and complete hearing. The court, taking additional evidence pursuant to Neb. Rev. Stat. § 14-414 (Reissue 1991), fоund that Stratbucker had in fact complied with the conditions of the waiver. In particular, the court found (1) that Stratbucker had expended substantial amounts of money in attempting to comply with the waiver; and (2) that a December 14, 1988, report by Omaha’s chief building inspector indicated that Stratbucker had complied with the terms of the StratbuckerBеnson agreement. The court therefore reversed the board’s August 24, 1989, ruling and extended the conditional waiver until August25,1991, conditioned on two other matters.
In the interim between the filing of Stratbucker’s appeal to the district court and the court’s July 16,1990, order, the city of Omaha revoked three building permits and a sign permit held by Stratbucker. On September 7, 1990, the district court ordered the board to rеissue the sign permit and two of the building permits to Stratbucker (hereinafter referred to as the “permits”). The board then appealed to the Court of Appeals.
The board argued to the Court of Appeals that the district court had erred by extending the conditional waiver and by ordering that the permits be reissued. Stratbucker cross-aрpealed, arguing that although the district court had correctly extended the zoning waiver, it had acted arbitrarily by extending the waiver only until August 25,1991.

The Court of Appeals, in an opinion filed on August 11, 1992, first held that the board’s argument regarding extension of the waiver was moot because the extension period had since passed.

v.
Zoning Bd. of Appeals,
Stratbucker then petitioned this court to further review the decision of the Court of Appeals. Restated, Stratbucker alleges that the Court of Appeals erred by (1) failing to find that the district court abused its discretion by arbitrarily extending the waiver for only 13 months; and (2) reversing the district court’s order that directed the board to reissue the permits.
Recently, in
Bowman v. City of York,
[A] district court may disturb a decision of such a board [of adjustment] only if... the decision was illegal or is not supported by the evidence and is thus arbitrary, unreasonable, or clearly wrong. In deciding whether a board’s decision is supported by the evidence, the district court shall consider any additional evidence it receives.
. . . [A]n appellate court reviews the decision of the district court and . . . irrespective of whether the district court took additional evidence, the appellate court is to decide if, in reviewing а decision of the board of adjustment, the district court abused its discretion or made an error of law. Where competent evidence supports the district court’s factual findings, the appellate court will not substitute its factual findings for those of the district court.

Neb. 548,
Although the zoning board of appeals is created pursuant to a differеnt statute than is a board of adjustment, the portions of the statutes relating to the standard of review are virtually identical. See Neb. Rev. Stat. §§ 14-408, 14-413, 14-414, 19-908, and 19-912 (Reissue 1991). As a result, our analysis in
Bowman
concerning the applicable standards for review of a decision of a board of adjustment also applies to the review of a decision from the zоning board of appeals. Cf.
Mossman
v.
City of Columbus,
We first address Stratbucker’s contention that the Court of Appeals erred when it reversed the district court’s order that the board reissue the revoked permits. The Court of Appeals correctly noted that the city council is given the powеr to issue building permits. Neb. Rev. Stat. § 14-419 (Reissue 1991). However, nothing in the statutes implies that the board has a similar power. The board is given express power to issue special permits, but only to the State, political subdivisions, and public utilities. Neb. Rev. Stat. § 14-412(Reissue 1991).
The board has authority to hear and decide appeals from, and review decisions or orders of, administrative officials. It also hears and decides matters referrеd to it by ordinance. Neb. Rev. Stat. § 14-409 (Reissue 1991). The reissuance of the permits was never appealed to the board, nor was it required by ordinance. Instead, the permit issue came to the board via the district court — eliminating the “appeal and review” inherent in the board’s nature. The proper entity to issue the building permits was the city оf Omaha. See § 14-419. However, the city was not made a party to this action.
Moreover, the permit issue was not raised in Stratbucker’s amended petition to the district court. Rather, it was raised in a separate motion. Section 14-414 states that the district court may reverse, modify, or affirm “the decision brought up for review.” The permit issue was nоt brought up for review from the board. Hence, the district court had no authority to deal with the permit issue.
The district court made an error of law by ordering the board to reissue the revoked permits. The Court of Appeals correctly *73 reversed the district court’s judgment on this issue. Stratbucker’s first assignment of error is without merit.
With regard to the conditionаl waiver, Stratbucker argues that instead of a 13-month extension, the extension should have been indefinite — continuing until the conditions of the waiver are violated. We first must determine the meaning of the relevant language from the waiver.
Stratbucker’s conditional waiver provides, in pertinent part: “Approval to operate a farmer’s market ... on the following conditions . . . that this waiver be conditioned on a one year review basis . . . .” Stratbucker contends that the waiver provided for a one-time review which, if satisfied, would cause the waiver to remain in effect as long as the Trust complied with the waiver’s conditions. The board, on the other hand, argues that the waiver рrovides for annual reviews. Under an “annual review” interpretation, if the reviewing panel found Stratbucker to be in compliance with the waiver’s conditions, then the waiver would be extended only until the following year’s review.
Because the language of the waiver lends itself to two plausible constructions, each with differing legal ramificаtions, we must construe the waiver to determine its meaning. The board, which is neither a court nor a legislature, is a governmental authority that affects the rights of private parties through adjudication or rulemaking. As ..such, it functions primarily as an administrative agency. See
Bowman, supra
(citing 1 Kenneth C. Davis, Administrative Law Treatise § 1:2 at 9 (2d ed. 1978)). See, also,
Florentine
v.
Town of Darien,
Generally, for purposes of construction, a rule or order of an administrative agency is treated like a statute. See,
Texas Liquor Control Bd. v. Attic Club, Inc.,
The interpretation of a statutе (or zoning waiver) is a question of law, and we are therefore obligated to reach a conclusion independent of the decision reached by the trial court.
Dowd
v.
First Omaha Sec. Corp.,
Furthermore, when construing a waiver, we must give effect, if possible, to all parts of the waiver. Whenever possible no word, sentence, or clause will be rejected as meaningless, and nothing plain, direct, and unambiguous will be ignored. Cf.
Sorensen
v.
Meyer,
When viewed in the context of the entire waiver, the “one year review” lаnguage clearly indicates an annual review. The relevant language of the waiver provides:
Approval to operate a farmer’s market ... on the following conditions: That the operation be conducted from April 1st to December 31st only, and during the hours of 8:00 a.m. to sundown during the summer months and to 8:00 P.M. [sic] during the Spring and Fall of the year; that the directional sign on the property be no larger than 4 x 4 ft----; that the roof sign be no larger than 3x16 ft.; that this waiver be conditioned on a one year review basis; that the agreement signed between S. P. Benson and the applicant... be complied with; [and] that the parking lot may remain unpaved____
(Emphasis supplied.)
*75 Stratbucker acknowledges in its brief that the waiver’s existence is conditioned on continued compliance with its terms. Brief for appellee at 4. Viewed with this realization in mind, the lаnguage of the waiver indicates that the “one year review” is simply one of a number of conditions that must be satisfied for the waiver to continue.
The “review” language is part of a list of items delineated as conditions. Under Stratbucker’s characterization, after the first year of the waiver the review requirement effectively “disaрpears” from the list, while the other conditions remain in effect. Stratbucker’s characterization treats the review condition as a one-time requirement, while the remainder of the list indicates a continual duty of compliance. That characterization reads a distinction into the series not warranted by the language of thе waiver; we will not read any such distinction into the waiver.
Moreover, the inclusion of the word “basis” in the review clause indicates that a satisfactory review is simply one more factor that must be met for the waiver to continue. If the “one year review” language had not been followed by the word “basis, ” or if the review clause had preceded the introduction of the listed “conditions,” Stratbucker’s construction of the waiver would be more persuasive. Such is not the case, however. We determine that the conditions listed in the waiver, including the condition of review, are recurrent.
However, in addition to indicating that the conditions are recurrent, the language of the waiver also indicates that, depending on the actions of Stratbucker and the board, the waiver could be extended. Nothing in the waiver itself limits its period to only 1 year. Furthermore, the annual nature of the reviews anticipates future extensions.
We now turn to the district court’s factual findings as affecting the extension of the waiver. The district сourt found that the board did not give Stratbucker a fair and complete hearing. The court thus took additional evidence and provided the “review” to which Stratbucker was entitled under the waiver. At trial, the district court determined that Stratbucker had complied with the terms of the waiver and reversed the board’s refusal to extend the waiver.
*76 As stated previously, we are to decide whether the district court abused its discretion or made an error of law when reviewing the board’s decision. Cf., Barrett, supra; Bowman, supra. Where competent evidence supports the district court’s factual findings, this court will not substitute its own factual findings for those of the district court. Cf., Barrett, supra; Bowman, supra. After reviewing the record, we find that the evidence suрports the district court’s findings that Stratbucker complied with the terms of the waiver. In particular we note, as did the district court, that Omaha’s chief building inspector found Stratbucker to be in compliance with the terms of the waiver. Moreover, Stratbucker’s certificate of occupancy, issued 20 days before the 1989 board meeting, stated thаt the market premises were “found to comply with all the applicable provisions of the Omaha Municipal Code.” The record does not indicate that the district court erred or abused its discretion when it reversed the board’s refusal to extend the waiver.
We thus come to the critical question: Did the district court err by extending the waiver only until August 25,1991? We find that it did.
Although the district court extended the conditional waiver for an additional 13 months, the court made no provision for what would occur at the end of that period. As such, the waiver simply terminated on August 25, 1991, without the possibility of another extension. Stratbucker argues that although the district court correctly extended the waiver, the 13-month time limit had no logical basis and was therefore arbitrary. We agree.

In addition to its certificate of occupancy, Stratbucker asserts that it also relied on the conditional waiver itself. The waiver is analogous to the certificate of occupancy in

and good faith reliance on the waiver therefore precludes its arbitrary revocation. See
Nuckles
v.
Allen,
Because the waiver was conditioned on compliance with its terms, including 1-year reviews, Stratbucker could not reasonably expect that substantial expenditures alone would guaranty the continued existence of the waiver. However, Stratbucker was justified in believing that if it made expenditurеs in a good faith attempt to comply with the waiver, it would at least be given the opportunity to show compliance — and thereby perhaps receive another extension. See, A. C. Nelsen Enterprises, Inc., supra; Nuckles, supra.
The conditional waiver provided for yearly reviews to determine compliance with its terms. The district court determined that Stratbucker had, in fаct, complied with those terms during the first year of the waiver. The district court thus was justified in extending the waiver for an additional year. However, the district court and Court of Appeals erred by allowing the waiver to terminate by the mere expiration of that 1-year period. Because Stratbucker expended substantial sums in good faith relianсe on the waiver, the waiver could not be arbitrarily revoked. See A.C. Nelsen Enterprises, Inc., supra. Pursuant to the terms of the waiver, Stratbucker should have been provided a review at the end of the extension period to determine whether another extension should have been granted.
We affirm the Court of Appeals’ reversal of the district *78 court’s judgment on the question of permit reissuance. However, we revеrse the Court of Appeals’ ruling that the district court did not err by extending the conditional waiver only until August 25, 1991. We therefore remand the cause from the cross-appeal to the Court of Appeals with directions to remand to the district court for proceedings not inconsistent with this opinion.
Affirmed in part, and in part reversed and remanded with directions.
