If the thermostat reading differs more than 4-degrees Fahrenheit from the actual room temperature taken at a height of five feet above the floor in the center of the room where the thermostat is located, the builder shall take such action as is necessary to bring the variance within the standard.   (4) Heating and cooling equipment shall be installed and secured according to the manufacturer's instructions and specification and shall not move excessively. If the heating or cooling equipment is not installed and secured in accordance with manufacturer's instructions and specifications or moves excessively, the builder shall take such action as is necessary to properly install and secure the equipment. (c) Performance Standards for Vents, Grills or Registers.   (1) A vent, grill or register shall operate easily and smoothly when applying normal operating pressure. If a vent, grill or register does not operate easily and smoothly when applying normal pressure when adjusting, the builder shall repair the vent, grill or register so that it operates with ease of use when applying normal operating pressure.   (2) A vent, grill or register shall be installed in accordance with the Code and manufacturer's instructions and specifications and shall be secured to the underlying surface. If a vent, grill or register is not installed and secured in accordance with the performance standard in this paragraph, the builder shall take such action as is necessary to bring the variance within the standard. (d) Performance Standards for Ductwork.   (1) Ductwork shall be insulated in unconditioned areas according to Code. If ductwork is not insulated in unconditioned areas in accordance with the Code, the builder shall take such action as is necessary to bring the variance within the standard stated in this paragraph.   (2) Ductwork shall be secured according to the manufacturer's instructions and specifications and it shall not move excessively. If the ductwork is not secured according to the manufacturer's instructions and specifications or moves excessively, the builder shall take such action as is necessary to bring the variance within the standard stated in this paragraph.   (3) Ductwork shall be sealed and shall not separate or leak in excess of the standards set by the Code. If the ductwork is not sealed, is separated or leaks in excess of the standards set by the Code, the builder shall take such action as is necessary to bring the variance within the standard stated in this paragraph.
SUBCHAPTER D	PERFORMANCE STANDARDS FOR FOUNDATIONS AND MAJOR STRUCTURAL COMPONENTS OF A HOME SUBJECT TO A MINIMUM WARRANTY PERIOD OF TEN YEARS
RULE §304.100		Performance Standards for Major Structural Components

(a) Performance Standards for Slab Foundations.   (1) Slab foundations should not move differentially after they are constructed, such that a tilt or deflection in the slab in excess of the standards defined below arises from post-construction movement. The protocol and standards for evaluating slab foundations shall follow the "Guidelines for the Evaluation and Repair of Residential Foundations" as published by the Texas Section of the American Society of Civil Engineers (2002), hereinafter referred to as the "ASCE Guidelines" with the following modifications:     (A) Overall deflection from the original construction elevations shall be no greater than the overall length over which the deflection occurs divided by 360 (L/360) and must not have more than one associated symptom of distress, as described in Section 5 of the ASCE Guidelines, that results in actual observable physical damage to the home.     (B) The slab shall not deflect after construction in a tilting mode in excess of one percent from the original construction elevations resulting in actual observable physical damage to the components of the home.   (2) If measurements and associated symptoms of distress show that a slab foundation does not meet the deflection or tilt standards stated in paragraph (1) of this subsection, a third-party inspector's recommendation shall be based on the appropriate remedial measures as described in Section 7 of the ASCE Guidelines. (b) Performance Standards for Major Structural Components of a Home other than Slab Foundations.   (1) Floor over pier and beam foundations.     (A) A floor over pier and beam foundation shall not deflect more than L/360 from its original construction elevations and have that movement create actual observable physical damage to the components of the home identifiable in Section 5.3 of the ASCE Guidelines.     (B) If a floor over pier and beam foundation deflects more than L/360 from its original construction elevation and the movement has created actual observable physical damage to the components of a home identifiable in Section 5.3 of the ASCE Guidelines, a third-party inspector's recommendation shall be based on applicable remedial measures as described in Section 7 of the ASCE Guidelines.   (2) Structural components.     (A) A defined structural component shall not crack, bow, become distorted or deteriorate, such that it compromises the structural integrity of a home or the performance of a structural system of the home resulting in actual observable physical damage to a component of the home.     (B) If a structural component of a home cracks, bows, is distorted or deteriorates such that it results in actual observable physical damage to a component of the home, the builder shall take such action as is necessary to repair, reinforce or replace such structural component to restore the structural integrity of the home or the performance of the affected structural system.   (3) Deflected structural components.     (A) A structural component shall not deflect more than the ratios allowed by the Code.     (B) If a structural component of the home is deflected more than the ratios allowed by the Code, the builder shall to repair, reinforce or replace such structural component to restore the structural integrity of the home or the performance of the affected structural system.   (4) Damaged structural components.     (A) A structural component shall not be so damaged that it compromises the structural integrity or performance of the affected structural system.     (B) If a structural component is so damaged that it compromises the structural integrity or performance of a structural system of the home, the builder shall take such action as is necessary to repair, reinforce or replace such structural component to restore the structural integrity of the home or the performance of the affected structural system.   (5) Separated structural components.     (A) A structural component shall not separate from a supporting member more than 3/4 of an inch or such that it compromises the structural integrity or performance of the system.     (B) If a structural component is separated from a supporting member more than 3/4 of an inch or separated such that it compromises the structural integrity or performance of a structural system of the home, the builder shall take such action as necessary to repair, reinforce or replace such structural component to re-establish the connection between the structural component and the supporting member, to restore the structural integrity of the home and the performance of the affected structural system.   (6) Non-performing structural components.     (A) A structural component shall function as required by the Code.     (B) If a structural component does not function as required by the Code, the builder shall take such action as is necessary to bring the variance within the standard stated in subparagraph (A) of this paragraph.
