OPINION
STEVE McKEITHEN, Chief Justice.
Appellant Gene E. Bates appeals the trial court's order dismissing his suit against the City of Beaumont for want of jurisdiction. See Act of May 15, 2001, 77th Leg., R.S., ch. 413, § 12, 2001 Tex. Gen. Laws 754, 758 (current version at TEX. LOC. GOV'T CODE ANN. § 214.0012(a) (Vernon Supp.2007)). Bates raises nine issues for our consideration. We reverse and remand.

BACKGROUND
This proceeding began as a suit by Bates for injunction and temporary restraining order against the City of Beaumont ("the City"). In his original petition, Bates sought to restrain the City from demolishing his commercial property located at 2510 Calder. The City responded by filing a plea to the jurisdiction, in which it asserted that the trial court lacked jurisdiction of the case because Bates did not file suit within thirty days of the date the City sent him notice of the City Council's decision to demolish the property. The trial court conducted an evidentiary hearing on Bates's application for temporary restraining order.
At the evidentiary hearing, the trial court heard evidence that in a letter to Bates, dated April 4, 2006, the City notified Bates that, pursuant to "City of Beaumont Ordinance Article III, Section 14-50 and 14-51[,]" it intended to hold a "Dilapidated Structure Public Hearing" during the. City Council meeting scheduled for April 25, 2006. The letter also informed Bates he could attend the hearing to show cause as to why the building should not be demolished. The City also introduced a certified mail receipt, which indicated that the letter was delivered on April 6, 2006. In addition, the City introduced a certified letter of April 28, 2006, in which it informed Bates that unless he substantially completed a work program, the City would demolish the property without further notice. Said letter was marked "unclaimed" and returned to the City after three delivery attempts.
*926 The City subsequently promulgated ordinance number 06-026, in which it declared that Bates's property was a public nuisance and that the building "for want of repairs, or by reason of age or dilapidated condition, [is] likely to cause or promote fires that would endanger persons or property." The ordinance also ordered Bates to demolish the building within ten days or execute a work program, or the building would be demolished without further notice. Bates filed his lawsuit on October 5, 2006.
Bates testified that he did not think the structure was unsafe, that "[t]here is not even a brick that's out of place on the building[,]" and that he has made several improvements since the property sustained hurricane damage. According to Bates, the building is a steel-framed car wash. Bates testified that he discovered a notice on the door of the property as he was driving by, and that the notice said that the City intended to demolish the building. Upon reading the notice, Bates contacted the City, and he learned the City had sent him a notice letter that he did not receive. Bates testified that he received the City's previous letter regarding the City's intention to conduct a hearing on the property at a City Council meeting, and Bates appeared and spoke at the meeting. As a result of the meeting, Bates repaired a leak on the roof and secured the building with plywood. Bates testified he did not receive any other mail from the City regarding the building "until the other day." Bates further testified that he had never knowingly ignored any certified mail. Bates provided his home address, which was the same address to which the City had sent all of the notice letters, and Bates testified, "[i]f letters were sent to that address, I should have received them. . . ."
Pam Loiacano, the demolition field supervisor for the City of Beaumont Building Code Department, testified that she initially inspected Bates's property on November 10, 2004, and the City filed a declaration that the property was a dangerous structure on December 1, 2004. Loiacano testified that on a subsequent, inspection on March 7, 2006, she could enter the rear section of the building. Loiacano's inspection revealed that the roof had deteriorated, the overhang had rotten material, some fascia board was rotten, and the rear garage door was open and damaged. Loiacano also observed that although the brick was in good condition, some of the trim work was rotted, and the inside of the building contained "human feces and lots of odors. There [was] wiring and piping . . . just hanging[.]" Although Loiacano did not climb onto the roof to inspect it, she viewed the front of the building through the windows and observed "quite a bit of water damage to the interior" and "a lot of mold and mildew and some water on the floor." In addition, Loiacano testified that there was evidence that drug users and prostitutes were gaining access to the building, and the City had received complaints about such activity from citizens.
Loiacano explained that she was unable to inspect the building's interior after March 7, 2006, because Bates had boarded the building. She opined that the building is substandard and should be demolished. However, Loiacano also testified that she could not say that the building was in danger of collapsing. On cross-examination, Loiacano explained, "I wasn't saying [the building] was unsafe. I' was saying it was substandard. If a building is secure and is in no danger of collapsing, . . . then it's not a dangerous structure. But it still doesn't mean that it meets code and is not substandard." According to Loiacano, pursuant to city ordinance, the building "is considered a dangerous structure because it does not meet city code."
*927 Loiacano also testified that the City published notices on April 12, 2006, and April 19, 2006, which informed the public of the scheduled April 25 hearing before the City Council. Loiacano explained that after the City sent the April 4, 2006, letter to Bates, Bates spoke at the City Council meeting. After the meeting, the City issued a "raze or repair" order regarding the property. Loiacano explained that once a building is tagged as a dangerous building, the owner must enroll in a work program and repair the building to "bring it back into compliance[.]" Loiacano testified that the City sent a letter to Bates on April 28, 2006, and that said letter informed him that he must enroll in a work program. According to Loiacano, the City published Ordinance 06-026 in the local newspaper. Loiacano testified that the City also sent a certified letter to Bates on September 25, 2006, and someone signed for the letter.

ISSUE ONE
In his first issue, Bates argues the trial court erred in determining that it lacked subject matter jurisdiction. We review the trial court's jurisdictional ruling de novo. Mayhew v. Town of Sunnyvale, 964 S.W.2d 922, 928 (Tex.1998); City of Dayton v. Gates, 126 S.W.3d 288, 289 (Tex. App.-Beaumont 2004, no pet.), In doing so, we must determine whether Bates had alleged facts that affirmatively demonstrate the court's jurisdiction. Tex. Dep't of Parks & Wildlife v. Miranda, 133 S.W.3d 217, 226 (Tex.2004). In deciding whether Bates affirmatively demonstrated the court's jurisdiction to hear the cause, "we consider the facts alleged by the plaintiff and, to the extent it is relevant to the jurisdictional issue, the evidence submitted by the parties." Tex. Natural Res. Conservation Comm'n v. White, 46 S.W.3d 864, 868 (Tex.2001). We must liberally construe the pleadings in favor of jurisdiction. Peek v. Equip. Serv. Co. of San Antonio, 779 S.W.2d 802, 804 (Tex.1989). However, if the pleadings affirmatively negate the existence of jurisdiction, the trial court may grant the plea to the jurisdiction without giving Bates an opportunity to amend his pleadings. See County of Cameron v. Brown, 80 S.W.3d 549, 555 (Tex. 2002)"
The City's plea to the jurisdiction asserted, among other things, that the trial court lacked subject matter jurisdiction because Bates failed to file suit within thirty days of April 28, 2006, when the City issued its letter informing Bates that the City had decided to demolish the property. Ordinance 14-51 declares that all "dangerous buildings" as defined in ordinance 14-50 are "declared to be public nuisances and shall be repaired, removed or demolished as hereinafter provided." Beaumont Municipal Code (Tex.), Article III, § 14-51 (1985). Ordinance 14-52, which deals with the procedure to be followed by the City in ordering repair or demolition of a dangerous structure, states as follows:
(1) If, after inspection by the building official or designated enforcing officer, . . . a determination is made that the building is a dangerous structure, the building official or designated enforcing officer shall tag the structure and the owner shall be ordered by a certified letter to contact the building official or designated enforcing officer within fifteen (15) days from the date of said letter. The owner shall be ordered, by letter, to enroll in an official work program to repair the structure or demolish said structure within thirty (30) days.
(2) If a permit to repair or demolish said structure is not obtained from building codes and repairs or demolition are not completed within fortyfive (45) days of the date of the *928 letter provided for in subsection (1) above, the building official or designated enforcing officer shall give notice, by letter, to the owner of said structure to appear before the city council to show cause why said structure should not be demolished and at the cost of the owner. Building permits issued to repair a structure under an official work program shall have the same expiration date as the work program.
(3) . . . Failure to obtain substantial completion, as defined in the work program, within ninety (90) days from the date of initiating said program or failure to obtain a certificate of occupancy within the one hundred fifty-day period, the structure may be brought before the city council for a condemnation order without further notice to the owner. . . .
(4) Any vacant structure found to be a "dangerous structure" . . . shall be posted as provided in section 14-50 to prevent occupancy. It shall be unlawful for any person to occupy a structure that has been tagged as a "dangerous structure" in accordance with this section.
(5) All notices, as provided herein, shall be served by delivering same to the owner or agent in person, or by mailing the same certified to the residence or business address, if known, of such owner or agent, or by posting the same in a prominent place upon such building or structure.
Beaumont Municipal Code (Tex.), Article III, § 14-52(1)-(5) (1985). Section 214.001(r) of the Local Government Code states that "[w]hen a municipality mails a notice in accordance with this section to a property owner, lienholder, or mortgagee and the United States Postal Service returns the notice as "refused" or "unclaimed," the validity of the notice is not affected, and the notice is considered delivered." TEX. LOC. GOV'T CODE ANN. § 214.001(r) (Vernon Supp.2006). Section 214.0012(a) of the Local Government Code provides as follows:
(a) Any owner, lienholder, or mortgagee of record of property jointly or severally aggrieved by an order of a municipality issued under Section 214.001 may file in district court a verified petition setting forth that the decision is illegal, in whole or in part, and specifying the grounds of the illegality. The petition must be filed by an owner, lienholder, or mortgagee within 30 calendar days after the respective dates a copy of the final decision of the municipality is personally delivered or mailed to them by first class mail, certified return receipt requested, or such decision shall become final as to each of them upon the expiration of each such 30 calendar day period.
See Act of May 15, 2001, 77th Leg., R.S., ch. 413, § 12, 2001 Tex. Gen. Laws 754, 758 (current version at TEX. LOC. GOV'T CODE ANN. § 214.0012(a) (Vernon Supp: 2007)). Section 214.0012 of the Local Government Code waives the City's sovereign immunity when a plaintiff follows the procedures set forth therein. See generally Teague v. City of Jacksboro, 190 S.W.3d 813, 816-19 (Tex.App.-Fort Worth 2006, pet. denied) (Section 214.0012 waived the City's governmental immunity from suit when plaintiff complied with that statute's procedures for challenging a condemnation order by filing a petition within the thirty-day period.); see also Act of May 15, 2001, 77th Leg., R.S., ch. 413, § 12, 2001 Tex. Gen. Laws 754, 758 (current version at TEX LOC. GOV'T CODE ANN. § 214.0012(a) (Vernon Supp.2007)).
In this case, the evidence before the Court demonstrated that the City sent its *929 first notification letter on April 28, 2006, via certified mail to Bates's correct residential mailing address, where Bates had received a previous certified letter approximately three weeks earlier. The City argues that this letter was its final notice to Bates, and that the thirty day deadline began to run from that date. We disagree. Following the April 25, 2006 meeting of City Council, Bates began repairs on the building. The City apparently treated this as the equivalent of Bates, enrolling in a work program for the purpose of bringing the building to code. After re-inspecting the building, the City sent a second letter, this one dated September 25, 2006, informing Bates that the repairs were insufficient, and that the City would proceed with the demolition of the building. This second letter is the notification to Bates that a final decision had been reached by the City. It was from that date that Bates' thirty day deadline began to run. Bates's filed suit on October 5, 2006, well within thirty days from the date of the letter informing Bates of the City's final decision. Accordingly, the trial court erred in determining that it lacked subject matter jurisdiction of the case. See id. § 214.0012(a). We sustain issue one.

ISSUES TWO, THREE, FOUR, SIX, AND EIGHT
In issue two, Bates asserts that the trial court erred by not holding that the equal protection and due process provisions under the state and federal constitutions require that he receive actual notice of the proposed demolition. In issue three, Bates maintains the trial court erred by "refusing to hold that the equal protection and due-process considerations underlying Chapter 214 of the Local Government Code . . . require[d] that Bates must receive actual notice of any proposed demolition by the City of Beaumont by either certified mail, return receipt requested, or hand delivery of such notice." In issue four, Bates complains that the trial court erred "in not recognizing that the City's declaration that [the] structure was a public nuisance and fire hazard required that there be a jury trial on those issues." In issue six, Bates asserts that the trial court erred by ruling that the City could destroy the property despite "the City's acknowledgment in open court that it did not have evidence that the property was a `dangerous structure[,]'" and by failing to address whether the property was a public nuisance and fire hazard. In issue eight, Bates argues Chapter 214 of the Local Government Code is unconstitutional under the state and, federal constitutions because it permits destruction of property "without the receipt of proper notice by the owner of the precise grounds for the proposed destruction of the property[.]" We decline to address these issues, as they would afford no further relief than has been granted in our disposition of issue one.

ISSUES FIVE, SEVEN, AND NINE
In issue five, Bates complains that the trial court erred in finding that only Chapter 214 of the Local Government Code governed the demolition of the property. In issue seven, Bates maintains that the City "waived its reliance on Chapter 214 of the Texas Local Government Code" by declaring that Bates's property was a "public nuisance" rather than a dangerous structure." In issue nine, Bates argues Chapter 214 of the Local Government Code is unconstitutional "Rio the degree that [it] allows the City of Beaumont to demolish the Bates structure without first obtaining a trial court finding that it is a public nuisance[.]" The record reflects that Bates did not make these arguments before the trial court. Therefore, they have not been preserved for our review. See TEX.R.APP. P. 33.1(a)(1)(A).
*930 The judgment of the trial court is reversed, and the cause remanded for further proceedings consistent with this opinion.
REVERSED AND REMANDED.
