Warnings and revelations:

1991: New building code says homes must not leak but does not set out rules for popular new monolithic claddings.

1994: Prendos and others warn of "potential time bomb" in leaking and rotting new stucco homes.

1995: Regulations change to allow untreated timber with no resistance to rot. The cheaper product takes over after vigorous timber industry promotion.

April 1998: Philip O'Sullivan begins warning Building Industry Authority of widespread rot and leaks. He calls unsuccessfully for an action plan.

September 1999: Dr John Kinnonmonth, chairman of the committee which approved untreated timber, calls for the decision to be reviewed.

October 1999: Greg O'Sullivan warns BIA of "Cave Creek" disaster over rotting decks and balconies.

November 1999: Philip O'Sullivan sends the BIA graphic pictures of a rotting balcony.

May 2000: Forest Research scientist Mick Hedley publishes research showing boric treated timber resists rot but untreated timber does not - contrary to industry advertising.

November 2000: Philip O'Sullivan again warns of a widespread, significant problem in modern buildings and urges the use of treated timber or wall cavities to drain leaks. Again his advice is not accepted.

June 2001: The Herald reveals huge industry concern over the problem.

March 2002: An independent inquiry begins, chaired by former State Services Commissioner Don Hunn.

May 2002: The inquiry warns in its interim report of a potential "major systemic breakdown across the industry".

July 2002: The BIA admits it is considering a return to treated timber.

August 2002: Based on the inquiry team's strong recommendation, the BIA issues a public safety warning over rotting balconies.

September 2002: The Hunn report finds clear evidence of a significant and growing problem. It predicts a $240 million repair bill.

3.1 Timber treatments
Up to 1992, most timber used for house framing in New Zealand was radiata pine treated with boron. From the early 1990s, a range of alternative timber framing treatment options for radiata pine became available. From 1998 to April 2004, homes were often built with untreated kiln-dried radiata pine framing.

If the framing used is untreated or has a preservative treatment only effective against insects, it is more likely decay will be both severe and widespread in a leaky building.

The most reliable way of finding out what timber treatment (if any) has been used, is to take timber samples and have them tested in a laboratory. An assessment report completed on the building should provide some information on the type of timber treatment used in the building. However, the assessor is only able to access a limited part of the timber framing and it is quite common to find a mix of timber treatments in the framing of any individual building that have not been identified in the assessment report. If there are no markings on framing timber identifying the treatment type and level, it is safer to assume it is untreated.

好了我也不用纠结了，出了比cv高25%房东还是不接，还有几万差距，谈不拢就算啦 ...

看来你说的这个不是我说的那个，那个成交了。

3.1 Timber treatments

这里找到个依据----From 1998 to April 2004, homes were often built with untreated kiln-dried radiata pine framing.-----实际上就是1997 - 2004时间段内碰到untreated的几率最大.

我有住过三十还是二十年代的房子，感觉旧是旧，但是还挺结实的。现在的漏水屋，不到十年，房梁都能用手指按出洞，那快一百年的房子还不摇摇欲坠吗？我想以前没有处理，但是肯定有其他方法，比如木材的品种，就好比中国什么金丝楠木，通过木材自己的一些特性来避免此类事情发生

是呀， 1952年前的房子， 木框架都是没处理过的， 也没听说有什么漏水屋， 所以漏水屋可能跟木头有没有处理过没什么关系， 还是跟外墙或者用什么木头关系大些吧?

以前也treat的，只是那几年的没treat

再早的，很多老的都有少许毛病，不像有问题的plaster那么多漏水。还有一些老房子，稍微有点问题的，可能被拆了吧。。。。。我猜的

Wet boric or boron salts timber treatments were first introduced in 1952 – before that, native timber and some of the first radiata pine framing was used untreated. From 11 September 1995, NZS 3602:1995 Timber and wood-based products for use in building allowed the use of untreated timber for framing provided it was kiln-dried and that its in-service moisture content did not exceed 18%. The change in the standard was cited in Building Code compliance document B2/AS1 on 28 February 1998. (Any use of untreated kiln-dried timber before this would have to have been consented as an Alternative Solution.)
写了， 1952年前的是没处理过的

可能那个时期的房子只能买砖的。砖的一般有缝，有缝就通风不会烂。或者买了持有几年再卖呗。

两个理解，

那个年代的造的不好的房子已经被拆除了，留下的都不错

那个年代，和97-04的非plaster房子一样，漏水风险相对04之后的房子，比较高，如果保养的好没问题，保养的不好就比较麻烦。而97-04的plaster 房子风险更高，设计施工保养差了一点就是大麻烦。

不要担心, 洋人会买的.

嗯，我说呢。我一直有听说，以前的房子用料都很好，质量比现在好，只不过盖房的技术可能比较老，还有规范和现在的不一样。90年代前，改动房子根本不需要什么康嫂的批准什么的

97-04？那么97年前的房子应该没问题了？

97-04遇到的几率最高，其次是1990~1997之间的。
