I'm moving my dryer from outside to inside, so is there a maximum length a dryer vent duct can be? It will be about 45 ft. if i do it like it is now. I'm trying to do it w/o moving my vent hood. So is this going to be a fire hazard, and will it be up to code most building codes?

Looks as though you'll be moving your vent hood. You could use the old one, and 45' of duct but you would need an in-line exhaust booster to do it - and they are expensive. Additionally, the whole system would be expensive to install.
From a safety, and expense, standpoint, it's recommended that you relocate your termination. With the right tools, it's a snap.
Good luck.

The International Residential Code for new homes allows a maximum of 25 feet for a dryer vent. The duct must be metal. Deduct 5 feet of length for every 90 degree elbow.
I don't know what local codes might be in effect where you live; check with your local building inspector.
The blower motor in your dryer is probably not nearly powerful enough to push the heavy moisture-laden air 45 feet. I would look for a way to get it down to 25 or less.

Are we talking about a clothes dryer here? If so a 45' run of vent pipe is way too long. The air flow will be practically nil by the time it reaches the outside and the lint will collect along the interior walls something fierce, till it shuts the whole thing down. 20 - 25' would be the longest run I'd even consider giving you a decent job of getting rid of the moisture and lint from the clothes being dried.

in my opinion you will be doing yourself an injustice by putting the dryer where it cannot properly breathe. an equal amount of air must move freely into and out of a dryer. 45 feet of dryer vent hose is just too much. lint buildup and improper ducting can cause a multitude of problems. from excessive dryer usage .premature motor failure. the dryer should be near an outside wall and not going up into the attic either. se only aluminum 4 in vent pipe and dont exceed 4 ft at the most.

Every manufacturer has a maximum recommended vent length. It will very by brand & model number. They also can tell you how many feet (from the total allowed) you deduct for each elbow. Check with the manufacturer.

Could you possibly work up a venting system through a nearer window or something????? If your home is basically frame construction (not stone or brick), it shouldn't be too big of deal locating a vent in a new, closer location......just thinking out loud
Good luck
