2005 Model house.
Are floor outlets permitted? I dont see the need as there was a wall outlet within 4-6 feet. (Pictured)
The dryer vent was the length of the house. I dont believe dryers are designed to push that amount of air. Are there codes to the distance a dryer vent is?
The double wall vent was touching the wooden material and I noted as a concern.(Pictured)
Thanks
Dave
Hi David,
The dryer vent is not allowed to be longer than 25 ft. You have to deduct 2.5 ft for a 45 degree turn and 5 ft for a 90. Those are from memory I would have to look it up to make sure.
David,
if I would like to confuse you I would just refer you to NEC Art. 220. :twisted: However, I spare you the headaches and let you know that the maximum number of outlets is not defined for a residential house even so you could get the impression after reading the article. :shock:
Looking at your picture I want to add that you can not count floor recepticles as part of the required outlets unless it is 18in to the wall and second that in hallways >= 10ft you need to have only one also not counting the floor ones.

Clearance to Combustibles. A 1-inch clearance (air space) to combustible materials must be maintained, when using Round B-Vent, regardless of the pipe diameter. 
Hi David!
I hope that this helps.

Geez, I think all that info was given in previous answers, and in a much more reasonable amount of space.
Hi James!
With all due respect, the previous answers were correct. Yet, we live in a litigious society and in order to protect yourself and your client there is nothing wrong with including details such as “exceptions” and or details.
If you treat all inspections as if they are “Going to Trial” then you will be better off for it. When it comes to a so-called “Negative comment” in a report too many Real Estate agents will challenge an inspector and ask them “Where did you get that information?
It is better to able to quote “Chapter & Verse.

Clothes Dryer Exhaust
M1501.1 General.
M1501.2 Exhaust duct size.
M1501.3 Length limitation.
As times and technology change there are exceptions to every rule. Example;
Exceptions:

Where a clothes dryer booster fan is installed and not readily accessible from the room in which the dryer is located, a permanent identifying label shall be placed adjacent to where the exhaust duct enters the wall. The label shall bear the words “This dryer exhaust system is equipped with a remotely located booster fan.”
Where the make and model of the clothes dryer to be installed is known and the manufacturer’s installation instructions for such dryer are provided to the building official, the maximum length of the exhaust duct, including any transition duct, shall be permitted to be in accordance with the dryer manufacturer’s installation instructions.
You will find that one of the many benefits of being a member of NACHI is that you will find knowledgeable and experienced inspectors {like the two listed above} who are willing to take the time and effort to help their fellow inspectors.
This is also a good way for you to build your Technical Database / library.
I wish you well, and Good Luck in your Home Inspection Business.
Thanks Frank. I couldn’t agree more, this message board alone is worth the price of admission. It’s a great resource
More questions about new construction.
I cant find the information on when the condensate from the air conditioner needed to go to a bowl and then a sealed drain. The one today was spilling on the floor.
I have seen numerous half baths we no heat source in the room. I take it it is allowable to be heated from the other rooms. Is this correct?
Thanks
Dave
David;
I believe that condensate drains should be directed to indirected waste.
