4x4 Rafters


I have an elderly customer who's house has fire damage. Another contractor starting the restoration but was fired. They demo the interior down to studs in all but two bedrooms. Her husband added a 11x11 room which is used for a closet and a 18x12 sunroom without a permit. He used 4x4 posts for rafters in both rooms. The work was done 20 yrs ago.

My question is how will an inspector react to this type of construction during inspections? Will he require her to bring rafters to code?

If so the closet roof currently a 2:12 pitch and would need to be raised to accommodated new rafters. The sunroom has a 4:12 pitch and I'm thinking with could add the correct rafters from the interior and not have to reconstruct the entire roof. Probably remove shingles to nail plywood to new rafters.

As anyone experience a situation like this and have some cost effective tips.

Well if it's existing, it is what it is. If the part your doing is new you bring it up to code. An inspector would give you a hard time if you add to the incompliance.

The 4x4 maybe ok but would have to look into the AWC post and beam section. It's not part of the IRC

Re: 4x4 Rafters


It's visible because of drywall and insulation was removed, but there's no structural damage.

Re: 4x4 Rafters


This depends on the BI. It's existing and you aren't modifying it or repairing it, so it shouldn't be a problem. If it shows signs of structural failure or rot or excessive sagging, you may be on the hook.

General rules. AHJ has 5 years to act on an unpermitted structure. 20 years is way out of that.

Existing is what it is, as said above. The exception would be anything that's an imminent danger, for instance. If they sign off, they pick up liability.

Current firecode has to be met, there is no grandfathering.

That must be a Maine thing. I haven't had to deal with any major ones myself, but I hear about non permitted stuff all the time that's old but comes back to bite HO's when they try to renovate or sell.

It may even vary jurisdiction to jurisdiction. Multiple cities up here.

Re: 4x4 Rafters


I just checked out some permits a year or do ago, and the guy bulit an unpermitted porch, and then included it as existing on a permit to build an entry like a portico or mudroom.

Maybe he'll sneak it by that way, maybe not. Entry roof was framed 2X4s on the flat, so I'm guessing he won't call for inspection.

Re: 4x4 Rafters


I dont know whats going on with permits now here.

I had a customer forced to tear out a finished basement on the house they bought because there were no permits on record for it. All of the sudden no one care about permits. New work and technical exceptions otherwise direct replacement work no ones looking which opens pandoras box.

I think its a way of hiding undocumented workers quite honestly in addition to the super high taxes people bitch about. The loose regs to make remodeling easier will invite more hackery
