APPENDIX 1 - LEGISLATIVE HISTORY FOR ORDINANCE 9544.

Ordinance 9544, the Mechanical Code for Los Angeles County, was originally adopted on March 14, 1968. Ordinance 9544 was kept up to date by later amendments until the entire Mechanical Code was repealed and replaced by Ordinance 95- 0070. Major amendments to Ordinance 9544, each adopting the current edition of the Uniform Mechanical Code, are listed and briefly described in Table A below; amending ordinances are also listed.

Table B covers the legislative history of the county's own Mechanical Code provisions before Ordinance 95-0070 was passed, and gives the specific legislative history for each section.

Table C shows the correspondence between sections of the 1991 Uniform Mechanical Code and the 1994 Uniform Mechanical Code. The 1991 Uniform Mechanical Code was extensively revised and renumbered to create the 1994 Uniform Mechanical Code.

Provisions of Ordinance 95-0070 and its amendments now comprise Title 29 of the Los Angeles County Code.
