      (1) "Assessor" means the person responsible for establishing property assessments 
for purposes of a town's grand list and includes a board of assessors;
      (2) "Field review" means the process by which an assessor, a member of an assessor's staff or person designated by an assessor examines each parcel of real property in 
its neighborhood setting, compares observable attributes to those listed on such parcel's 
corresponding property record, makes any necessary corrections based on such observation and verifies that such parcel's attributes are accounted for in the valuation being 
developed for a revaluation;
      (3) "Full inspection" or "fully inspect" means to measure or verify the exterior 
dimensions of a building or structure and to enter and examine the interior of such 
building or structure in order to observe and record or verify the characteristics and 
conditions thereof, provided permission to enter such interior is granted by the property 
owner or an adult occupant;
      (4) "Real property" means all the property described in section 12-64;
      (5) "Revaluation" or "revalue" means to establish the present true and actual value 
of all real property in a town as of a specific assessment date;
      (6) "Secretary" means the Secretary of the Office of Policy and Management, or 
said secretary's designee; and
      (7) "Town" means any town, consolidated town and city or consolidated town and 
borough.
      (b) (1) Commencing October 1, 2006, each town shall implement a revaluation not 
later than the first day of October that follows, by five years, the October first assessment 
date on which the town's previous revaluation became effective, provided, a town that 
opted to defer a revaluation, pursuant to section 12-62l, shall implement a revaluation 
not later than the first day of October that follows, by five years, the October first assessment date on which the town's deferred revaluation became effective. The town shall 
use assessments derived from each such revaluation for the purpose of levying property 
taxes for the assessment year in which such revaluation is effective and for each assessment year that follows until the ensuing revaluation becomes effective.
      (2) When conducting a revaluation, an assessor shall use generally accepted mass 
appraisal methods which may include, but need not be limited to, the market sales comparison approach to value, the cost approach to value and the income approach to value. 
Prior to the completion of each revaluation, the assessor shall conduct a field review. 
Except in a town that has a single assessor, the members of the board of assessors shall 
approve, by majority vote, all valuations established for a revaluation.
      (3) An assessor, member of an assessor's staff or person designated by an assessor 
may, at any time, fully inspect any parcel of improved real property in order to ascertain 
or verify the accuracy of data listed on the assessor's property record for such parcel. 
Except as provided in subdivision (4) of this subsection, the assessor shall fully inspect 
each such parcel once in every ten assessment years, provided, if the full inspection of 
any such parcel occurred in an assessment year preceding that commencing October 1, 
1996, the assessor shall fully inspect such parcel not later than the first day of October 
of 2009, and shall thereafter fully inspect such parcel in accordance with this section. 
Nothing in this subsection shall require the assessor to fully inspect all of a town's 
improved real property parcels in the same assessment year and in no case shall an 
assessor be required to fully inspect any such parcel more than once during every ten 
assessment years.
      (4) An assessor may, at any time during the period in which a full inspection of 
each improved parcel of real property is required, send a questionnaire to the owner of 
such parcel to (A) obtain information concerning the property's acquisition, and (B) 
obtain verification of the accuracy of data listed on the assessor's property record for 
such parcel. An assessor shall develop and institute a quality assurance program with 
respect to responses received to such questionnaires. If satisfied with the results of 
said program concerning such questionnaires, the assessor may fully inspect only those 
parcels of improved real property for which satisfactory verification of data listed on 
the assessor's property record has not been obtained and is otherwise unavailable. The 
full inspection requirement in subdivision (3) of this subsection shall not apply to any 
parcel of improved real property for which the assessor obtains satisfactory verification 
of data listed on the assessor's property record.
      (c) The following shall be available for public inspection in the assessor's office, 
in the manner provided for access to public records in subsection (a) of section 1-210, 
not later than the date written notices of real property valuations are mailed in accordance 
with subsection (f) of this section: (1) Any criteria, guidelines, price schedules or statement of procedures used in such revaluation by the assessor or by any revaluation company that the assessor designates to perform mass appraisal or field review functions, 
all of which shall continue to be available for public inspection until the town's next 
revaluation becomes effective; and (2) a compilation of all real property sales in each 
neighborhood for the twelve months preceding the date on which each revaluation is 
effective, the selling prices of which are representative of the fair market values of the 
properties sold, which compilation shall continue to be available for public inspection 
for a period of not less than twelve months immediately following a revaluation's effective date. Nothing in this subsection shall be construed to permit the assessor to post a 
plan or drawing of a dwelling unit of a residential property's interior on the Internet or 
to otherwise publish such plan or drawing.
      (d) (1) The chief executive officer of a town shall notify the Secretary of the Office 
of Policy and Management that the town is effecting a revaluation by sending a written 
notice to the secretary not later than thirty days after the date on which such town's 
assessor signs a grand list that reflects assessments of real property derived from a 
revaluation. Any town that fails to effect a revaluation for the assessment date required 
by this section shall be subject to a penalty effective for the fiscal year commencing on 
the first day of July following such assessment date, and continuing for each successive 
fiscal year in which the town fails to levy taxes on the basis of such revaluation, provided 
the secretary shall not impose such penalty with respect to any assessment year in which 
the provisions of subsection (b) of section 12-117 are applicable. Such penalty shall be 
the forfeit of the amount otherwise allocable to such town pursuant to section 7-536, 
and the loss of fifty per cent of the amount of the grant that is payable to such town 
pursuant to sections 3-55i, 3-55j and 3-55k. Upon imposing said penalty, the secretary 
shall notify the chief executive officer of the amount of the town's forfeiture for said 
fiscal year and that the secretary's certification to the State Comptroller for the payments 
of such grant in said year shall reflect the required reduction.
      (2) The secretary may waive such penalty if, in the secretary's opinion, there appears 
to be reasonable cause for the town not having implemented a revaluation for the required 
assessment date, provided the chief executive officer of the town submits a written 
request for such waiver. Reasonable cause shall include: (A) An extraordinary circumstance or an act of God, (B) the failure on the part of any revaluation company to complete 
its contractual duties in a time and manner allowing for the implementation of such 
revaluation, and provided the town imposed the sanctions for such failure provided in 
a contract executed with said company, (C) the assessor's death or incapacitation during 
the conduct of a revaluation, which results in a delay of its implementation, or (D) an 
order by the superior court for the judicial district in which the town is located postponing 
such revaluation, or the potential for such an order with respect to a proceeding brought 
before said court. The chief executive officer shall submit such written request to the 
secretary not earlier than thirty business days after the date on which the assessor signs 
a grand list that does not reflect real property assessments based on values established 
for such required revaluation, and not later than thirty days preceding the July first 
commencement date of the fiscal year in which said penalty is applicable. Such request 
shall include the reason for the failure of the town to comply with the provisions of 
subsection (b) of this section. The chief executive officer of such town shall promptly 
provide any additional information regarding such failure that the secretary may require. 
Not later than sixty days after receiving such request and any such additional information, the secretary shall notify the chief executive officer of the secretary's decision to 
grant or deny the waiver requested, provided the secretary may delay a decision regarding a waiver related to a potential court order until not later than sixty days after the 
date such court renders the decision. The secretary shall not grant a penalty waiver under 
the provisions of this subsection with respect to consecutive years unless the General 
Assembly approves such action.
      (e) When conducting a revaluation, an assessor may designate a revaluation company certified in accordance with section 12-2b to perform property data collection, 
analysis of such data and any mass appraisal valuation or field review functions, pursuant 
to a method or methods the assessor approves, and may require such company to prepare 
and mail the valuation notices required by subsection (f) of this section, provided nothing 
in this subsection shall relieve any assessor of any other requirement relating to such 
revaluation imposed by any provisions of the general statutes, any public or special act, 
the provisions of any municipal charter that are not inconsistent with the requirements 
of this section, or any regulations adopted pursuant to subsection (g) of this section.
      (f) Not earlier than the assessment date that is the effective date of a revaluation 
and not later than the tenth calendar day immediately following the date on which the 
grand list for said assessment date is signed, the assessor shall mail a written notice to 
the last-known address of the owner of each parcel of real property that was revalued. 
Such notice shall include the valuation of such parcel as of said assessment date and 
the valuation of such parcel in the last-preceding assessment year, and shall provide 
information describing the property owner's rights to appeal the valuation established 
for said assessment date, including the manner in which an appeal may be filed with 
the board of assessment appeals.
      (g) The secretary shall adopt regulations, in accordance with the provisions of chapter 54, which an assessor shall use when conducting a revaluation. Such regulations 
shall include (1) provisions governing the management of the revaluation process, including, but not limited to, the method of compiling and maintaining property records, 
documenting the assessment year during which a full inspection of each parcel of improved real property occurs, and the method of determining real property sales data 
in support of the mass appraisal process, and (2) provisions establishing criteria for 
measuring the level and uniformity of assessments generated from a revaluation, provided such criteria shall be applicable to different classes of real property with respect 
to which a sufficient number of property sales exist. Certification of compliance with 
not less than one of said regulatory provisions shall be required for each revaluation and 
the assessor shall, not later than the date on which the grand list reflecting assessments of 
real property derived from a revaluation is signed, certify to the secretary and the chief 
executive officer, in writing, that the revaluation was conducted in accordance with 
said regulatory requirement. Any town effecting a revaluation with respect to which an 
assessor is unable to certify such compliance shall be subject to the penalty provided 
in subsection (d) of this section. In the event the assessor designates a revaluation company to perform mass appraisal valuation or field review functions with respect to a 
revaluation, the assessor and the employee of said company responsible for such function 
or functions shall jointly sign such certification. The assessor shall retain a copy of such 
certification and any data in support thereof in the assessor's office. The provisions of 
subsection (c) of this section concerning the public inspection of criteria, guidelines, 
price schedules or statement of procedures used in a revaluation shall be applicable to 
such certification and supporting data.
      (h) This section shall not require the revaluation of real property (1) designated 
within the 1983 Settlement boundary and taken into trust by the federal government for 
the Mashantucket Pequot Tribal Nation before June 8, 1999, or (2) taken into trust by 
the federal government for the Mohegan Tribe of Indians of Connecticut.
