FOREWORD

Housing Standards, Canada, 1963 provides detailed specifications to amplify the

performance called for in Part 9 of the National Building Code. A specially printed edition of these Standards serves as the regulations for construction of houses, as defined in Part 9, National Building Code of Canada, 1960 edition, under the National Housing Act: this special edition can be obtained from Central Mortgage and Housing Corporation. The 1960 edition of the National Building Code differs from earUer editions in its regulations for housing in three important ways.

First - Regulations for houses containing one or more dwelling units are now con-solidated and form the new Part 9, providing for the first time in one part of the National Building Code a complete statement of all minimum requirements for housing.

Second - Details of practice have, in most cases, been excluded from Part 9; it is these regulations which form the core around which the Housing Standards of Canada 1963 are developed.

Third - The coverage of technical requirements for housing has been greatly extended.

A municipality which has accepted the National Building Code as its building by-law will find in Part 9 the legal minimum requirements for housing with which an owner must comply. Some of these are specific, detailing exactly what he is required to do. Others refer to specifications (such as material specifications) and in those cases the complete specification is not included in the text. The remainder refer to "good practice" a require-ment that can be regulated only by example. It is impossible to include every example or variation of practice in the law and in the 1960 Code this has not been attempted. Instead, requirements for good practice in common usage have been assembled in this Supplement. This Supplement is intended to serve as a reference specification, always with the proviso that there are variations of good practice which may be equally satisfactory and that should be permitted. To permit such variations the customary permissive clause containing the usual safeguards is included in Part 9. (Clause 9.1.1)

Housing Standards, Canada, 1963 contains information on subjects which are Dot

mentioned in the National Building Code. This information is required for its other role, that of providing regulations for house building under the National Housing Act. To avoid confusion between the two kinds of subject matter an analytical index has been provided in the Standards. This shows which items in the Standards supplement the National Building Code and which do not; the material which supplements the National Building

Code Is In heavy type and that which does not Is in light type. In addition, every article In the Natiol18l Building Code which refers to the Standards Is marked thus", thus

forming a further link between the two documents.

Users of the Standards, and particularly those who consider its use as a supplement

I)

to Part 9 of the National Building Code, are requested to note carefully the difterence between the Standards in heavy and light type. Both are minimum requirements but the former are related directly to the National Building Code and include subjects considered suitable for municipal by-laws. The latter are likewise minima for their Intended purpose but the subjects are those which are not likely to receive recognition in enabling legislation. Where a municipality wishes to adopt some of these Standards as examples of good practice which satisfy the by-law requirements, provision is made in the analytical index for indicating the decisions made.

Part 9 and Appendices A-D

The above remarks refer to Chapters 1·9 of the Housing Standards. To avoid reference to another book, Part 9 NBC has been bound in with these Chapters and four Appendices have been included. Appendix A contains Span Tables for joists which is a revised edition of "Span Tables for Wood Joists and Rafters" (l'echnical Note #30, prepared by the Forest Products Research Branch, Department of Forestry, Ottawa, and printed in 19(1); Appendix B contains Span Tables for bollt.up wood beams; Appendix C contains Span Tables for steel beams; and Appendix D contains a description of the grade marks which are now to be found on lumber for purposes of identification. With the inclusion of all this material, Supplement No. 5 Is, therefore, a complete reference to minimum requirements and standards for houses containing one or more dwelling units in which there is not more than one dwelling unit above another and there are not more than two storeys above the top of the foundation where the building contains more than

one dwelling unit, with the exception of detailed requirements for plumbing which are to

be found in Part 7 of the Code.

Conclusion

The provisions of the National Building Code and so of Part 9 contained herein, are the minimum desirable requirements for buildings in Canada, necessary for the protection of the public, specifically with respect to structural suffi.ciency, fire prevention and public health. The Housing Standards explain how the minimum performance requirements for housing, as laid down in Part 9, can be achieved In practice. They contain also suggestions of current good minimum practice regarding other aspects of residential design not legally required by Part 9. Tabular material Is included as a convenience to users, the values given being based on the written requirements of the Standards.

The minimum character of all the contents of this Supplement must be stressed. It

is not a "Manual of Good Housing Design" but a statement of the minimum essential requirements that housing must meet. Individual designers may go beyond any of the provisions herein presented, so that the latter constitute no bar to the development of housing design in Canada but are only a statement of min.imum standards that must be met in the public interest.
