Amend HB 1257 (Senate committee printing) by adding the 
following SECTION to the bill, appropriately numbered, and 
renumbering existing SECTIONS accordingly:
	SECTION ___.  (a)  Subchapter B, Chapter 11, Tax Code, is 
amended by adding Section 11.135 to read as follows:
	Sec. 11.135.  CONTINUATION OF RESIDENCE HOMESTEAD EXEMPTION 
WHILE REPLACEMENT STRUCTURE IS CONSTRUCTED; SALE OF PROPERTY.  (a)  
If a qualified residential structure for which the owner receives 
an exemption under Section 11.13 is rendered uninhabitable or 
unusable by a casualty or by wind or water damage, the owner may 
continue to receive the exemption for the structure and the land and 
improvements used in the residential occupancy of the structure 
while the owner constructs a replacement qualified residential 
structure on the land if the owner does not establish a different 
principal residence for which the owner receives an exemption under 
Section 11.13 during that period and intends to return and occupy 
the structure as the owner's principal residence.  To continue to 
receive the exemption, the owner must begin active construction of 
the replacement qualified residential structure or other physical 
preparation of the site on which the structure is to be located not 
later than the first anniversary of the date the owner ceases to 
occupy the former qualified residential structure as the owner's 
principal residence.  The owner may not receive the exemption for 
that property under the circumstances described by this subsection 
for more than two years.
	(b)  For purposes of Subsection (a), the site of a 
replacement qualified residential structure is under physical 
preparation if the owner has engaged in architectural or 
engineering work, soil testing, land clearing activities, or site 
improvement work necessary for the construction of the structure or 
has conducted an environmental or land use study relating to the 
construction of the structure.
	(c)  If an owner receives an exemption for property under 
Section 11.13 under the circumstances described by Subsection (a) 
and sells the property before the owner completes construction of a 
replacement qualified residential structure on the property, an 
additional tax is imposed on the property equal to the difference 
between the taxes imposed on the property for each of the years in 
which the owner received the exemption and the tax that would have 
been imposed had the owner not received the exemption in each of 
those years, plus interest at an annual rate of seven percent 
calculated from the dates on which the differences would have 
become due.
	(d)  A tax lien attaches to property on the date a sale under 
the circumstances described by Subsection (c) occurs to secure 
payment of the additional tax and interest imposed by that 
subsection and any penalties incurred.  The lien exists in favor of 
all taxing units for which the additional tax is imposed.
	(e)  A determination that a sale of property under the 
circumstances described by Subsection (c) has occurred is made by 
the chief appraiser.  The chief appraiser shall deliver a notice of 
the determination to the owner of the property as soon as possible 
after making the determination and shall include in the notice an 
explanation of the owner's right to protest the determination.  If 
the owner does not file a timely protest or if the final 
determination of the protest is that the additional taxes are due, 
the assessor for each taxing unit shall prepare and deliver a bill 
for the additional taxes plus interest as soon as practicable.  The 
taxes and interest are due and become delinquent and incur 
penalties and interest as provided by law for ad valorem taxes 
imposed by the taxing unit if not paid before the next February 1 
that is at least 20 days after the date the bill is delivered to the 
owner of the property.
	(f)  The sanctions provided by Subsection (c) do not apply if 
the sale is:
		(1)  for right-of-way; or                                              
		(2)  to this state or a political subdivision of this 
state to be used for a public purpose.
	(g)  The comptroller shall adopt rules and forms to implement 
this section.
	(b)  Section 11.26, Tax Code, is amended by adding 
Subsections (n) and (o) to read as follows:
	(n)  Notwithstanding Subsection (c), the limitation on tax 
increases required by this section does not expire if the owner of 
the structure qualifies for an exemption under Section 11.13 under 
the circumstances described by Section 11.135(a).
	(o)  Notwithstanding Subsections (a), (a-3), and (b), an 
improvement to property that would otherwise constitute an 
improvement under Subsection (b) is not treated as an improvement 
under that subsection if the improvement is a replacement structure 
for a structure that was rendered uninhabitable or unusable by a 
casualty or by wind or water damage.  For purposes of appraising the 
property in the tax year in which the structure would have 
constituted an improvement under Subsection (b), the replacement 
structure is considered to be an improvement under that subsection 
only if:
		(1)  the square footage of the replacement structure 
exceeds that of the replaced structure as that structure existed 
before the casualty or damage occurred; or
		(2)  the exterior of the replacement structure is of 
higher quality construction and composition than that of the 
replaced structure.
	(c)  Section 11.261, Tax Code, is amended by adding 
Subsections (l) and (m) to read as follows:
	(l)  Notwithstanding Subsection (d), a limitation on county, 
municipal, or junior college district tax increases provided by 
this section does not expire if the owner of the structure qualifies 
for an exemption under Section 11.13 under the circumstances 
described by Section 11.135(a).
	(m)  Notwithstanding Subsections (b) and (c), an improvement 
to property that would otherwise constitute an improvement under 
Subsection (c) is not treated as an improvement under that 
subsection if the improvement is a replacement structure for a 
structure that was rendered uninhabitable or unusable by a casualty 
or by wind or water damage.  For purposes of appraising the property 
in the tax year in which the structure would have constituted an 
improvement under Subsection (c), the replacement structure is 
considered to be an improvement under that subsection only if:
		(1)  the square footage of the replacement structure 
exceeds that of the replaced structure as that structure existed 
before the casualty or damage occurred; or
		(2)  the exterior of the replacement structure is of 
higher quality construction and composition than that of the 
replaced structure.
	(d)  Section 23.23(f), Tax Code, is amended to read as 
follows:              
	(f)  Notwithstanding Subsections (a) and (e) and except as 
provided by Subdivision (2), an improvement to property that would 
otherwise constitute a new improvement is not treated as a new 
improvement if the improvement is a replacement structure for a 
structure that was rendered uninhabitable or unusable by a casualty 
or by wind [mold] or water damage.  For purposes of appraising the 
property under Subsection (a) in the tax year in which the structure 
would have constituted a new improvement:
		(1)  the appraised value the property would have had in 
the preceding tax [last] year if the casualty or damage had not 
occurred [in which the property was appraised for taxation before 
the casualty or damage occurred] is considered to be the appraised 
value of the property for that year, regardless of whether that 
appraised value exceeds the actual appraised value of the property 
for that year as limited by Subsection (a) [last year in which the 
property was appraised for taxation for purposes of Subsection 
(a)(2)(A)]; and
		(2)  the replacement structure is considered to be a 
new improvement only if:
			(A)  the square footage of the replacement 
structure exceeds that of [to the extent it is a significant 
improvement over] the replaced structure as that structure existed 
before the casualty or damage occurred; or
			(B)  the exterior of the replacement structure is 
of higher quality construction and composition than that of the 
replaced structure.
	(e)  This section applies only to ad valorem taxes imposed 
for a tax year beginning on or after the effective date of this Act.
