Ready For Your Deck Inspection?

As safety concerns drive ever more stringent deck codes, remodelers and builders find ways to ensure projects pass inspection

February 22, 2019

There are 40 million decks in the U.S., according to the North American Deck and Rail Association (NADRA), with maybe half of them code compliant. Meanwhile, deck failures and the injuries that result are pushing states and municipalities to establish more rigorous codes. “The codes have changed over time and the people in our industry are adapting to it,” says Mike Brueggenjohann, vice president of California Custom Decks, in St. Louis, which builds about 150 projects a year.

Local building inspections, of course, are the means of enforcing code compliance. With decks, that typically means separate inspections for footings, framing, and “final,” if not also rough and final electrical on more sophisticated projects.

What can be a challenge, Brueggenjohann says, is “the consistency in which rule changes apply” if your company is working in multiple municipalities, each with its own departments and inspectors.

Option That’s Not An Option

Failing an inspection equates to a confidence issue, says Bryan Miller, of Outback Deck, in Atlanta. “What happens if I’m looking at the consumer, saying I know I’m the most expensive and here are our value propositions, and then I fail the first inspection?" Miller says. "Confidence erodes quickly.”

But things happen. For Andrew York, owner of ProDeck Construction in San Diego, failing an inspection is a schedule snafu. Correcting something cited doesn’t require “a huge amount of extra labor or additional materials,” York says, “but it slows us down so much, especially with footings.”

Seasoned deck builders have long since turned their failed building inspections into a process for ensuring that the work passes. York, for instance, notes that when he first started his company in 2010, failed inspections on his jobs were as high as 10%. In the last few years—2018 for instance—ProDeck Construction has logged only a single failed building inspection.

Experience proves a useful teacher. For Bay Area deck builder and designer Gary Marsh, whose four-decade career includes many award-winning projects, it took only one inspection failure, 38 years ago—a foundation situation involving rebar situated a little too close to dirt—to convince him it wasn’t anything he wanted repeated. Because of that instance, now the designer shows up at township planning departments with designs mindful of property lines, easements, setback requirements, square footage to floor area ratio components, and anything else code requires.

“We submit a full set of structural drawings,” Marsh says, which, in an area of “severe hills,” are closely scrutinized by an engineer. After that, says Marsh, “it’s a matter of implementing what you’ve indicated in your structural drawings you are going to do.”

Just Be There

For deck builders completing many projects week in and week out, time might not allow for such meticulous planning. The bigger challenge is to address issues encountered on site in a way that at least conforms to code.

Deck builders routinely encounter any number of difficulties they must not only solve, but explain to an inspector. Adding additional concrete to footings when a buried trash pit is encountered, moving a stairway a foot or two, all that. Some point out that simply being there to explain is hugely helpful in passing inspections; York, for instance, is always present for them. 

“One of the biggest things we found to ensure a higher rate of passing inspection is just being there, to answer questions and concerns,” Brueggenjohann adds. That can be tricky because sometimes inspections get called in without an exact time for the inspector’s visit. But making the extra effort is worth it, Brueggenjohann says, because otherwise the inspector shows up at an address with no one there. “There are plans on site, but they don’t know the project, and they’re moving from one site to the next,” he says. “If you’re there to interpret and provide plans, that’s always going to help.”

Expecting the Inspector

And if, when the inspector arrives, there is a situation that needs explaining, it could help to be preemptive. “Be prepared to discuss anything that differs from the approved plans,” says Matt Breyer, NADRA president and owner of Breyer Construction in Reading, Pa. “It happens and sometimes it’s actually better to bring these items up, along with the reasoning about why things were changed, rather than waiting for the inspector to notice.”

All agree that questioning an inspector’s observations, or disputing decisions, gets you nowhere. “It’s like arguing with a cop,” says Brian Altmann, owner of DBS Remodel, in Poughkeepsie, N.Y. First and foremost, be friendly and professional.

“The challenge,” says Brueggenjohann, is that “we all have to work together. You want to make sure that they’re on the team. So our guys are trained not to argue." Rather than  dispute, refer to plans, and logically explain. The person on site might not be the one you talked to at the township.

“Code passing should have been addressed back with the design stage and plan review,” Breyer points out, “but often we find that we’ll get approval from one inspector, and the 'other guy’ is sent out to run the site visit and sees things differently. It helps to keep a cool head in these situations. If you’ve got approval for how it’s built, that helps a lot, along with having a copy of the current IRC codes either on site or quickly available on your phone."

Zero Defects

Miller, whose company builds its high-end projects in some 37 Atlanta-area municipalities, says he sees startling differences among them when it comes to permitting and inspections. In some, “the requirements are much easier;” in others, securing a permit takes three or four weeks and requires a full set of architectural plans with an engineer’s stamp.

To minimize chances for failing an inspection, Outback created a Zero Defects checklist form for every stage of a deck project. It includes, in illustrated detail, what the result should look like. In footings, for instance, “the dimensions, all the parts and pieces that make it that footing” are listed. Project managers are required to sign off on each.

But, Miller says, it’s still possible to fail an inspection. “I could fail a footings inspection because last night we got four inches of rain and water got in,” he says. The important thing is to ensure that every phase is built according to the deck prescriptive on which Zero Defects checklists are based. And project managers “need to inspect everything at the front end: every physical connection, every area according to the specs, drawings and code, to make sure it’s right, that we’re following the process. That allows us to secure the site to pass that inspection.”

But how about when failed inspections are a matter of tired or irksome personalities? Miller points out that it helps to be aware of what that local building inspector is up against. “In a metro area, everybody’s overwhelmed,” he says. “They’re in the office by 6:30 a.m. to get their layout for the day. The GPS is telling them where to go next. The last thing we want to do is slow their day down.”

The question contractors should be asking themselves, he says, is, “How can we help that guy be better and more efficient?”

On Your Side

And when it comes to that, there are ways to get inspectors on your side. For instance, carpenters at DBS Remodel have a monthly meeting in the company’s conference room and on several occasions have invited local building inspectors to answer questions about how codes are changing and how they interpret it, Altmann says.

Foremen at ProDeck Construction make a point of introducing homeowners to the inspector that’s calling. “I tell the homeowner that we’re expecting the inspector, and it would help if they’re there," York says. "It seems like when homeowners are out there, introducing themselves and part of the conversation, they’re more likely to pass us.”

York has another method of ensuring his projects pass inspection, too. “I have a deal with my crew,” he says. “If we pass, I buy them all burritos. If we fail, they don’t get burritos. But that’s enough for them to double-check the plans, make sure all the details are right, that the dimensions in the footings are right, and when we pass they’re really excited.”

Hey thanks for the article, I specialize in repairs only, due to contractors not doing what they need to do. It's interesting just to note, the gentlemen installing the post cover picture. I noticed here in Colorado, the way the flashing is installed on the home, would fail. The zip isn't a waterproofing system 100%, so water gets trapped in between the ledger and the home, therefore damage starts. I don't know, I thought is was interesting to see this. If this is ok where this deck is being built, Well if would fail for sure, here in Colorado. I don't know if this was a test for the mind, but anyway, thought I would bring in up.

Thanks for the article, it was good

Thanks for the comment, Jim.

I shot the photo in question as part of a larger video project with Professional Remodeler

Colorado does, indeed, have progressive codes, and as you know, the newest version of the IRC calls for continuous self-adhered flashing behind deck ledgers. The jurisdiction in which the house in the photo was built has not adopted the 2018 code, but that is not why the builder chose to skip the additional self-adhered membrane behind the ledger.

The builder feels like the new code requirement is a a belt-and-suspenders approach that the code council adopted to make up for poor bulk water management and the likely hood of builders using low grade WRBs and creating trapped moisture issues. Not that there is anything wrong with a belt and suspenders, but if your pants fit, then you really do not need two backup systems.

This deck’s ledger flashing is integrated with a kickout starter strip below the vinyl siding that should push all water getting behind the siding out and away. Coupled with the water-tight decking product and the very-low perm WRB built into the wall sheathing, he feels there is very little chance of moisture problems creeping into the picture.

He better be right, because the house was built for his Mom!

Need my deck inspected for safety.

I agree the inspector may be a hurdle especially if you get one who's notoriously "tough". I've seen contractors schedule the inspection when they know a particular inspector will be on vacation, but that's not a consistently reliable strategy. You're probably right that avoiding arguments with the inspector and referring to the plans and the code is probably the best course of action.

I used to have more issues with deck inspection, early in my career. These days my team is excellent and we almost never have delays.

Ever since starting Raleigh deck builders (, I always stress with my team the importance of being detail-oriented and double checking work. It's embarrassing to not pass an inspection and causes costly delays and frustration from clients. Better to get it right the first time.

Thank you for sharing this wonderful information. I appreciate the effort of the inspector for the safeness of the deck. I love it! By the way, please do consider visiting our website to know more about our affordable drywall installation and repair services. Here's the link: ( Thanks!

We've had a lot of rain recently which has made safety a bigger issue, still I agree that we just have to slow things down and not worry about the project timelines otherwise the shortcuts will come back to bite us.
