Old codes

[bill1952]

House built in 1963 in Utah. UBC? And did it regulated 1&2 family dwellings?

If nothing has changed requiring a permit, any clue if a porch over 30" high would have been required to have guards? And if so, height of guard? I can only guess the 4" sphere rule was not in effect in 1963 but sure I'll be called out if it was.

Insurance and lenders may make the code question moot.

Is this an @Glenn question?

1963 was decades before the formation of the International Code Council. Back then, the three model building code organizations each had their own codes for commercial buildings, but they jointly promulgated the CABO One- and Two-Family Dwelling Code. The ICBO was one of the three organizations underwriting the CABO code.

My research suggests CABO was not till early 70's. I think 71 was the first edition? Not finding any codes - broadly at least - for houses. Would guess some jurisdictions had their own.

That's quite possible. In 1963 I was barely out of high school.

Yes 1971 was the first CABO code edition

I looked in the 1975 CABO and did not find the word "Deck" or "Platforms" in the index, however the 1993 CABO section 412.4 listed "platforms".

I believe the word "platform" is the prior term used for "Deck". Section 412.4.1 uses the 30-inch rule above a main floor which may have or may not have been forwarded into the current guard rail requirements?

The 4-inch sphere for spindle spacing came in after the 6-inch code requirement, that I know. It wasn't to long ago that the ledger was allowed to be nailed to house rim, obviously that has changed per new code adoptions.

I remember back when we had the UBC I had to learn to calculate lumber spans and the Building Chief (BO) had made a printout. I also remember other surrounding communities plagiarized that document, and builders and lumberyards all wanted a copy.

Thanks! Not very helpful to this question but quite fascinating. Lots of great prescriptive details, and lots of things not much changed even in 2024 IRC.

If I remember correctly the CABO code originally allowed 9" between balusters or horizontal bars. It was reduced to 6" in the late 80s, and later on to 4". BOCA was the same. I'm not sure about the other model codes.

In reviewing the 1954 document, it is sad that I seem to understand the older codes easier than the newer codes. The old codes had commentary and diagrams in the code which made it easy to understand. Now days, it seems that everyone is looking for the exceptions to the rules instead of compliance with the rules. I must be getting too old.

There are a lot more rules and a lot more "exceptions" in the code today.

Blame the lawyers.
