Six weeks. That is how long an undocumented 12 by 16 second story deck can stall a closing on a 1990s split level, and the wood does not have to be rotten for it to happen. The buyer’s inspector notes the deck, the county file shows no permit ever issued for it, and suddenly the lender’s appraiser has an open question that nobody in the transaction can answer with a document. Sellers in that spot almost never built the thing. They inherited it from an owner two deeds back, along with the water heater and the mulch beds, and found out it was undocumented the same week the buyer did. So the first call usually goes out to deck builders wentzville mo sellers can actually reach on short notice, because a repair with no paperwork behind it does not close the inspection item.
The argument of this guide is blunt. When a deck turns up unpermitted in the middle of a transaction, bringing it to code with a permit actually pulled usually costs less and lands sooner than negotiating a credit and hoping the buyer’s lender accepts the explanation. Credits get renegotiated on the day of signing. A closed permit does not.
Inspection Reports Surface Deck Paperwork Before Buyers Do
Home inspectors do not check permit records, and most of them say so in the report’s own disclaimers. What they do is describe the structure in writing, and the item that turns up most often on an older attached deck is the ledger, which is the board bolting the entire deck to the house. Washington State University Magazine, in its piece on making decks safer, states the case in terms worth treating as a rule in any older home: decks cause more injuries and loss of life than any other part of the home structure. Ledger attachment failure is the common cause of a deck collapse. So if the ledger is separating from the wall, the wood at the attachment point is soft or rotted, or the rails move when you lean against them, keep everyone off the deck and leave it unused until a licensed contractor or your local building official has inspected it.
The code language behind that connection is specific rather than vague. A March 2026 breakdown of ledger board requirements from ContractorGearLab put the 2026 International Residential Code standard at mechanical fasteners for the ledger attachment, with spacing that cannot exceed 6 inches on center at ends and joints. Which code edition a jurisdiction actually enforces varies, and the local building department is the only place that can confirm it for your address. Nails driven in on a Saturday afternoon do not meet that description, and an inspector who spots them writes them down whether or not a permit was ever pulled.
How many decks in this county are standing right now with no permit on file, I honestly cannot tell you. Nobody counts them, and the county record only speaks to the one address you ask about.
Questions Worth Asking A Deck Contractor First
A seller under contract is shopping in a hurry, which is exactly the moment a contractor’s answers matter more than the photo gallery. The useful questions here are administrative, not aesthetic. Ask them before the estimate conversation drifts off toward railing colors and lighting.
- Who pulls the permit, you or me? A good answer is that the contractor files it under their own license and hands you the permit number.
- Will you schedule the inspections and give me the signed results? A strong answer names the stages, usually footing, framing and final.
- What does your workmanship warranty cover, and for how long? Ask whether labor coverage and the decking manufacturer’s product coverage are separate documents, because they normally are.
- Can you point me to a permitted deck you finished in this county this year? A closed permit at a real address beats a portfolio photo every time.
A contractor who pulls permits under their own license and schedules the inspections is selling you a closed file, not only a deck. Keimar Contracting, as one example serving St. Charles and West St. Louis County, handles permits and inspections in house and backs its labor with a one year workmanship warranty that sits separate from the five year TimberTech product warranty on the boards. Whoever you hire, get the warranty terms in writing before the deposit changes hands, because a verbal warranty is impossible to enforce eight months later when a board cups.
Pricing A Permitted Rebuild Against A Stalled Closing
Run illustrative numbers on the deck in question, 12 by 16 and coming down to the footings, understanding these stand in for a real quote rather than replacing one. Say demolition and haul off at $900, new footings and posts at $1,700, framing and code compliant hardware at $3,200, composite decking with rail at $6,400, and $350 for the permit plus the inspection stops. That comes to $12,550, which sits under the fifteen thousand a seller in this scenario had set aside, and it ends with a signed final inspection attached to the property. Now price the other road. Thirty extra days on an $1,850 monthly payment, a $3,000 buyer credit talked down from an opening ask of $5,000, and a rate lock extension fee is real money spent to end up with the same undocumented deck.
If the framing, posts and footings check out and only the ledger connection and the rails are wrong, a retrofit with the correct hardware usually clears the item. If the posts are undersized or the footings are too shallow, a full rebuild is the cheaper end state, since a retrofit over bad framing gets opened up twice and paid for twice. The judgment call lives in the middle of those two, and a contractor worth hiring will tell you which side your deck falls on after crawling underneath it rather than after quoting from the driveway.
Documented Work Is What Closes The Deck Question
The deck that closes a sale is not the handsomest one on the street. It is the one with a permit number, a framing inspection and a final sign off attached to the address, which is why sellers who inherited someone else’s weekend project end up hiring deck builders Wentzville MO agents trust for permitted work rather than the cheapest bid on the list. You are buying the record as much as the lumber. Once a lender is in the room, the county file is the only opinion that counts, and the fastest way to end an open inspection item is to replace it with a document that says the structure was built, inspected and approved.
