What's Grandfathered, And Where Do The Codes Stop?


Got a kitchen remodel in an old house. Over a crawlspace, dirt floor. Dirt floor goes under the entire house. Want to tear off the kitchen subfloor and reposition floor joists since there's a larger than one inch drop in one corner.

Should we have to deal with the crawlspace at all? Vapor barrier? And the joists are 2x8s spanning 16'. Old style, thick 2x8s.

Where do you stop with satisfying today's codes? You'd have to rebuild the entire house.

Generally, a AHJ thing.

Determined by percentage of the structure you are renovating against the whole enchilada....

We really can't tell you--you'll have to contact your local AHJ for an authoritative answer.

But given the content of your post, you have a clue as to what should be done. Don't you think it would be a bit irresponsible not to do that whether legally required to or not?

Depends on the location of the house, in NJ they are very specific and inspector usually try to enforce incorrectly.

Here, anything you bring out of code by means of remodeling, has to be brought back to current code.

Re: What's Grandfathered, And Where Do The Codes Stop?


In NJ we have a Rehab code separate from the building code. It specifies what can and can't be done without filing for a permit. They break down into categories and so forth.

Check with your building department if the have something like this also.

It basically breaks down into sections something like this:

1. Ordinary maintenance and it tells you that:

(a) Ordinary maintenance to structures may be made without filing a permit application with or without giving notice to the construction official and it tells you what falls under that and it tells you what doesn't:
(b) Ordinary maintenance shall not include any of the following:
1. The cutting away of any wall, partition or portion thereof;
2. The removal or cutting of any structural beam or bearing support;
3. The removal or change of any required means of egress, or rearrangement of parts of a structure affecting
the exit way requirements;
4. Any work affecting structural or fire safety;
5. Any work that will increase the nonconformity of any existing building or structure with the requirements of the regulations;
ETC.

After that, you have another section that tells you when a permit is required.

2.Construction permits--when required

(a) It shall be unlawful to construct, enlarge, repair, renovate, alter, reconstruct or demolish a structure, or change the use of a building or structure, or portion thereof, or to install or alter any equipment for which provision is made or the installation of which is regulated by this chapter without first filing an application with the construction official, or the appropriate subcode official where the construction involves only one subcode, in writing and obtaining the required permit therefor.
ETC.

Good luck
