FACTS
Aрpellee, Frolich, built the house at issue here in 1976. The Sexsions, the first owners, lived in the house until 1981, when Appellants, the Jaworskys bought the house.
In July 1986 the new Owners allegedly noticed separations and cracks at the top of the house's garage door and in other areas. Owners also alleged that the patio was sinking.
PROCEDURAL HISTORY
Claiming breach of the implied warranties of habitability and workmanlike construction, and negligence, Owners sued Builder in October 1987, more than ten years after Builder finished building the house. Owners also joined the City of Oklahoma City, and Brewer Construction Company. 1 The trial court granted summary judgment for Builder on all issues, and Owners appealed.
Thе Court of Appeals, Division 1, reversed the trial court and remanded the case for further proceedings. The Court of Appeals held that Owners’ causes of action for breach of the implied warrantiеs of habitability and workmanlike construction did not arise until discovery of the defective construction in July 1986. Because Owners filed suit less than five years after discovery of the defects, said the Court of Appeals, their cause of action was timely filed.
Builder contended that 12 O.S.1981 § 109 barred Owners’ tort cause of action because Owner did not file suit until more than ten years after Builder completed the house. 2 The Court of Appeals disagreed, and held that Owners’ had two years from the date they discovered the defect within which to bring suit. This was so, the Court of Appeals held, though Owners had failed to meet the requirements of § 109 that suit be brought within “ten years аfter substantial completion of” the house.

I. Did the trial court err in holding that Owners’ theories of liability-concerning implied warranties were time barred?
II. Did the trial court err in holding that Owner’s tort causes of action did not survive the tenth anniversary of the completion of the house under § 109?
We answer no to both questions.
I.
Owners urge us not to review the Court of Appeals ruling on their implied warranty theories. According to Owners, Builder did not address the implied warranty theories in its Petition for Rehearing and Petition for Writ of Certiorari. We hold that Builder sufficiently dealt with the issue to preserve it for review.
The application of § 109 is expressly limited to
tort
causes of action. Consequently, Builder may not rely on § 109’s ten year limitation on Owners’ implied warranty causes of action. Owners’ warranty causes of action were based on contract, not tort,
Elden v. Simmons,
We now examine when the statute of limitations started to run on Builder’s breach of implied warranty. This claim sounds in сontract. We recently addressed when the statute of limitations starts to run for breach of a construction contract in
Vick,
Id. There, we adopted the rule that “the limitations period begins to run when the contraсt is completed.” In
Vick,
we expressly rejected the rule that a cause of action for breach of contract does not accrue until discovery of the defect. We did so because adoрting a discovery rule would create undesirable uncertainty by extending a builder’s potential contract liability indefinitely. Section 109 has solved this dilemma where tort actions are concerned, but § 109 does not aрply to contract actions. Here, the failure of Owners, and their predecessors, to discover the defects did not serve to extend the statutory period. Builder’s potential liability in contract for breach of implied warranty was extinguished on the fifth anniversary of the completion of the house. Giving home owners five years from the completion of construction of a home to sue for breach of the implied warranty of fitness is reasonable. We observed in
Jeanguneat v. Jackie Hames Const. Co.,
... the builder-vendor is not required to construct a perfect home, and in determining whether a house is defective, the test is reasonableness and not perfection, and that the duration of liability is likewise determined by the standard of reasonableness. [Emphasis added.]
Owners’ cause of action is barred by the applicable statute of limitations,
II.
Title 12 O.S.1981 § 109 provides that “No action in tort” arising from the construction of an improvement to real property “shall be brought ... more than ten (10) years after substantial completion of such an improvement.” The Court of Appeals interpreted § 109 to mеan that Owners had two years after discovery of the defect within which to sue. We disagree. We held in
St. Paul Fire & Marine Insurance. Co. v. Getty Oil Co.,
Owners claim that
Oklahoma City Municipal Improvement Authority v. HTB, Inc.,
Section 109 clearly limits the time within which an action must be brought to ten years. That the legislature meant exactly what it said is shown by looking at a previous version оf the statute and at 12 O.S.1981 § 110.
The original version of § 109, passed in 1967, gave only five years to property owners within which to discover any defects in construction. However, § 110, passed at the same time, effectively extеnded the potential time within which builders and others might be sued to seven years by giving plaintiffs two additional years within which to sue if they discovered a defect “during the fifth year after such substantial completion ...” 4 “But,” said the legislature, “in no event may such an action be brought more than seven (7) years after the substantial completion ...”
In 1978 the legislature amended § 109 by extending its time limit from five years to ten. 5 The legislature, however, chose not to аmend § 110. We interpret the legislature’s decision to leave § 110 unchanged to mean that it intended to insulate builders and others falling within the compass of § 109 from any action brought more than ten years after the substantial completiоn of the improvement. Just as the legislature in 1967 determined that a seven year time limit was reasonable, regardless of when the cause of action arose, it decided in 1978 that a ten year limit was reasonable, regardless of when the cause of action arose.
We pointed out in
St. Paul
that the legislature passed § 109 to set time limits on potential liability relating to improvements to real proрerty. We noted that, over time, this court and others introduced the “discovery rule,” which kept the statute of limitations from beginning to run until a defect was discovered; the old rule that there must be privity of contract betwеen a builder and a plaintiff was abrogated, Id.,
Before the Court of Appeals, Owners advanced several theories from which they argued that § 109 is unconstitutional. We reject these arguments. We held in St. Paul that § 109 was constitutional. There we said that a statute is рresumed to be constitutional,
unless the statute is “clearly, palpably and plainly inconsistent with the constitution.” [Citations omitted.]
Id.,
Owners claim that § 109 cut off their vested rights because they had less than two years to bring suit after their cause of action arose. This contentiоn is not supported by the facts. The legislature passed § 109 in 1978. Owners bought their house from the Sexsions in 1981. The requirement imposed by § 109 of having to sue within ten years after Builder completed the house existed before Owners cause of action arose in 1986 satisfies constitutional requirements. Owners were deprived of no vested rights by the operation of § 109.
CERTIORARI PREVIOUSLY GRANTED; COURT OF APPEALS OPINION VACATED; TRIAL COURT’S ORDER AFFIRMED.
Notes
. The trial court granted summary judgment to both the City of Oklahoma City and Brewer Construction Company. Owners did not appeal these judgments. Consequently, City and Brewer Construction are not parties to this appeal.
. 12 O.S.1981 § 109 provides:
No action in tort to recover damages
(i)for any deficiency in the design, planning, supervision or observation of construction or construction of an improvement to real property,
(ii) for injury to property, real or personal, arising out of any such deficiency, or
(iii) for injury to the person or wrongful death arising out of any such deficiency,
shall be brought against any person owning, leasing, or in possession of such an improvement or performing or furnishing the design, planning, supervision or observation of construction or construction of such an improvement more than ten (10) years after substantial completion of such an improvement.
. 12 O.S.1981 § 95 First, covers Owners’ warranty claims and gives them five years within which to sue.
. 12 O.S.1981 § 110 provides:
Notwithstanding the provisions of Section 1 оf this act, [12 O.S. § 109] in the case of such an injury to property or the person or such an injury causing wrongful death, which injury occurred during the fifth year after such substantial completion, an action in tort to recover damages for such an injury or wrongful death may be brought within two (2) years after the date on which such injury occurred (irrespective of the date of death) but in no event may such an action be brought more than seven (7) years аfter the substantial completion of construction of such an improvement.
. The legislature made another change in § 109 as well. That change is immaterial to this appeal. In addition to extending the time limit from five years to ten, the amended statute afforded protection under § 109 to owners, lessees and other occupants in addition to those who had done work on the improvement. The legislature passed this amendment in apparent response to our opinion in
Loyal Order of Moose Lodge 1785 v. Cavaness,
