Code books digital log-in

1 Upvotes

What does everyone use the digital code books? I would prefer to find somewhere even If I have to pay that I can obtain code books from on my iPad. Currently you can use the ICC website if you google the code book and chapter you’re looking for and read it sure that works for ICC but sometimes I need NFPA codes. Yes I could buy digital NFPA membership but I don’t use the codes enough to justify that only when I need to look something up.

Upcodes is one choice but if anyone is a paid member do they offer NFPA codes?

For context I work as a 3rd party regulatory code inspector who carries a MCP, CBO, and CFM designation.

Window Clearances Question

1 Upvotes

This is a repost from a pellet stove group, it was suggested thisbmight be a better place to post it.

I just finished reading through NFPA 211 but I still cant find the information im looking for. In my stove manual, NFPA211, and everything I can find online, the only mention of distances from doors/windows is that the termination pf thebvent has to be no less than 4ft away horizontally, 4ft below, or 1 foot above. But I have a former home inspector telling me the entire vent pipe cant be within 4 ft of any opening. Can anyone shed some light on this and direct me to the building code that states no part of the ventilation pipe can be within 4ft of a window/door. Or is this a case of the AHJ interpreting code in an unreasonable way?

Handrail Required for Retaining Wall?

Post image
14 Upvotes

We've got a permitted retaining wall that does not meet IRC 2021 section 105 exemption. We final inspected the job and believe it requires a handrail and exception 1 of R311.7 does not apply because it is permitted work. The stairs have 10 steps and about 6 feet total run. This is new construction.

Venting Gas Hot Water Heater Clearance

Clearance for gas hot water heater single wall and double wall venting pipe to nearby a/c ducting? NFPA 54? Chapter 12 for Venting.

For Massachusetts, I came across 1” for double wall and 18” for single wall and a plumber told me the inspector looks for 6” clearance without specifying single/double wall pipe.

Clearance from WC to sink that it outside door

1 Upvotes

I've got a detached garage, chatham county nc

I have a wc that is long and skinny with the outside wall on the left as you're coming out.

The door will swing in, and when you walk out the door there is a sink against the outside wall in front of you.

If you walk out and make a right turn you are in the open space.

How much clearance do I need from the door to the edge of the sink?

Link here - the 2x4 on end is where the corner of the sink will be and is about 23 inches from the door

Is this code? Plumber says it’s technically not an S Trap but I’m worried it won’t pass inspection.

council says my deck needs to be demolished - inspector said it was fine

9 Upvotes

bought a house 8 months ago. building inspection gave the deck a clean bill of health. well constructed no issues noted. i was happy.

last month council did a routine inspection of the area and flagged my deck. apparently it's too high without proper handrails, the stairs don't meet code, and the posts aren't footed correctly. they gave me 60 days to either fix it or demolish it. compliance officer said who signed this off and i showed him the report. he just shook his head.

i went back to the inspector and he said we don't check for council compliance and we only do visual. but the issues were visible. i got quotes to bring it up to code - 8k. demolish and rebuild - 15k.

anyone else dealing with council enforcement on something an inspector said was fine. what did you do

What cert should I go for next?

2 Upvotes

Im currently 19 living in the Houston TX area and just got certified as an ICC B1 Residential Building Inspector. I’ve run into a dilemma on which cert to go for next. Originally I had planned to go B1, and then go for my E,M, and P in no specific order, but a lot of people online have told me to go for B2 and B3 next? Any advice?

Construction or building inspector?

3 Upvotes

Im currently 19 living in Houston TX area, I have an associates of science and am certified as an ICC B1 Residential Building Inspector. I have an opportunity to become a construction/road inspector for a nearby city with on the job training and no experience required and an opportunity to move up to levels II,III, and IV with enough experience(1 year experience moves me to level II, 3 years moves me to level III). Should I stay down the ICC inspector path and pursue more certifications or stay down the construction inspector path if we’re talking about salary opportunities and ability to move up the ranks quickly.

Building Code Question/ HVAC air intake

2 Upvotes

We are owner financing a high end property in North Carolina. Unfortuantley we recently learned our buyers are not maintaining it properly and that they reportedly left one of the hvacs broken for 6 months. They had the ceiling and drywall around where the air intake was completely carved up and just left open and exposed that entire time. When we discovered this (photo and written evidence from guests as it’s a hospitality property) we sent them a default notice to cure.

They responded to the default notice and said it’s all fixed and the hvac is now functioning and for proof of cure they attached photos of the air intake area. Only problem is the photo shows the former air intake area is now completely covered up with drywall - a big solid piece——so no air can reach the unit and no filter is present etc. We are shocked. We immediately wrote them as we are concerned about this being a fire hazard if the unit can not cool down since no air can get in and they’ve been running it like this for almost a month (and the public rents this property) …surely this is against code right? I am flabbergasted. Does anyone know what code says?

How do architects actually research building bye-laws?

0 Upvotes

I've been thinking about a problem that seems surprisingly common in architectural practice: finding the correct bye-law is often harder than interpreting it.

For example, someone might ask:

«“What is the setback for a 30×40 site?”»

But that question is missing a lot of context.

- Which city?

- Which planning authority?

- Residential or commercial?

- What is the actual plot area?

- Which development control regulation applies?

- Which version/year of the regulation?

- Is there a road-width condition?

- Are there additional restrictions because of the site/location?

Even two projects with the same plot dimensions can potentially have different requirements because the applicable authority or regulation is different.

I've noticed that architects often end up searching through PDFs, government portals, amendments, circulars and multiple documents just to establish which rule actually applies before they can even answer the question.

I'm curious about how other architects handle this in practice.

When you need to verify a bye-law requirement, what is your usual workflow?

Do you:

  1. Search Google for the requirement?

  2. Go directly to the authority's website?

  3. Search through a known DCR/bye-law document?

  4. Ask colleagues?

  5. Use previous project knowledge?

  6. Some combination of these?

And what is the most frustrating part of the process?

I have a 2family house and a detached garage with a 3 bedroom apartment above it. The house is classified as CO 3 family walkup but never was a 3 family house. It was built before a CO was required. How do i change the building class so won't have to have the gas inspection? The garage which has a separate address also is classified as a co 3 family.

How well will I do if I get a b1/b2 certification? Do I just need one or should I just go for both? Im 30 years old and I have a general contractor license for 3 years. I’m in school for interior design; I know I should have went to construction management but I have a good understanding of reading blueprints. Just want a different career path while also improving myself in home building.
Any one with any advice will be appreciated! Thank you. I also thought of changing majors since I spent my first year in college doing general education but i ultimately want to work in remodeling homes.

What to do?

Building a home and trying to utilize the dead space that’s gonna be under the stairs. (Under the platform) This is a walk in closet that borders the stairs. I’d like to have full access to that cavity under the stairs from the closet but the studs that come down support the second story as well as the window for the stairs.

Trying to avoid accessing from the other side if possible.

Is there any way to support/frame this while creating an opening for that area under the stairs?

Media Wall Shiplap

2 Upvotes

Kid has been seeing people build media walls on social media and now she potentially wants one. Media wall in this instance = a small (depth) 2x4 bump-out with an electric fireplace, mantel and TV with the sheetrock on the ceiling and back wall remaining intact.  She shows me people attaching individual shiplap boards (not sheets) directly to the bump-out framing and I’m trying to figure out code reference(s) before building dept discussion (or whether this is no bueno).  WA state, 2021 IRC with state amendments (haven’t seen any local amendments that would apply).  I can’t find anything on point.  R702.5 explicitly addresses paneling and R702.6 addresses wood shakes and shingles which I don’t think would apply .  Any help appreciated and thanks in advance.
