(1) Performance standard: Non-structural
cracks are not unusual in concrete foundation walls. Cracks one-eighth inch in
width or greater are considered excessive.
(2) Builder/Warrantor responsibility: Repair
non-structural cracks in excess of one-eighth inch by surface patching. These
repairs should be made toward the end of the first year of ownership to permit
normal stabilizing of the home by settling.
ii. Possible Deficiency: Cracking of basement
floor.
(1) Performance standard: Minor cracks
in concrete basement floors are common. Cracks exceeding one quarter inch width
or one quarter inch in vertical displacement is a deficiency.
(2) Builder/Warrantor responsibility: Repair
cracks exceeding maximum tolerance by surface patching or other methods, as
required.
iii. Possible
Deficiency: Cracking of attached garage floor slab.
(1) Performance standard: Cracks in garage

excessive cracks by chipping out and surface patching or other methods, as may
be required.
iv.
Possible Deficiency: Cracks in attached patio slab.
(1) Performance standard: Cracks in excess of
one quarter inch in width or one quarter inch in vertical displacement are
defects. An "attached patio" is defined as a concrete patio slab on grade which
is an integral part of the home being structurally supported by footings, block
walls, or reinforced concrete and connected to the foundation.
(2) Exclusion: Patio slabs which are poured
separately, and abut the house are excluded from warranty coverage.
(3) Builder/Warrantor responsibility: The
Builder/Warrantor shall make repairs as required. Where cracks are caused by

portion which has settled and finish as close as possible to match the existing
surface. Where a major portion of the patio has cracked, the entire slab shall
be replaced.
v. Possible
Deficiency: Cracks in concrete slab-on grade floors, with finish flooring.
(1) Performance standard: Cracks which
rupture or significantly impair the appearance or performance of the finish
flooring material, is a deficiency.

required). Repair cracks as required, so as not to be apparent when the finish
flooring material is in place. Repair or replace finish flooring. (See "(h).
FINISHES").
vi. Possible
Deficiency: Uneven concrete floor slabs.
(1)
Performance standard: Except for basement floors or where a floor or portion of
floor has been designed for specific drainage purposes, concrete floors in
rooms designed for habitability shall not have pits, depressions or area of
unevenness exceeding 1/4 inch in 32 inches, or slopes in excess of 1/240 of
room width or length (i.e.: 10.0 wide room-not to exceed 1/2 inch out of
level).
(2) Builder/Warrantor
responsibility: Determine cause and repair/replace to meet the Standard. Where
applicable, surface patching is an accepted method of repair. Reinstall or
replace any finish flooring material as necessary.

is occupied.
(2) Builder/Warrantor
responsibility: Take whatever corrective action is necessary to treat, repair
or resurface defective areas.
ix. Possible Deficiency: Separation of brick
or masonry edging from concrete slab and step.
