The Inspector Opened the Crawl Space and Found a Marijuana Grow

The inspector came down the ladder holding his phone with the flashlight on, and he didn't say anything for a second, which was itself the message. Then: "You need to see this." I did not go into the crawl space. I looked at the photos instead, and there they were, photographed in professional series like a real estate listing nobody wanted: 40 marijuana plants in five-gallon buckets under grow lights, an irrigation line tapped into the home's water supply, and a ventilation duct running to a dryer vent. Under my house. In a house I was buying for $275,000. The inspection had cost $425 and was, up to that moment, the most boring hour of my home search.

the seller's 48 hours of surprise

The seller, a widower relocating to Arizona, claimed total ignorance thru his agent, and the part that took me days to accept: I believe him. The grow was sophisticated, with a timer system and a carbon filter, and it was in a crawlspace accessed from outside thru a hatch behind the garage, 30 inches tall, the kind of space an owner of that house, a 68-year-old man, had prolly entered once since 2011. His adult son had lived there for eight months the year before, and the son had, by every account including his own sheepish phone call to my agent, run the operation and then abandoned it when he moved out rather than breaking it down.

Legally, motive didn't matter much. What mattered was that the plants and equipment were contraband sitting on property I had under contract, that my lender would eventually ask about it, and that the discovery was documented in a written inspection report that now existed forever.

what the lawyer said, which was cheaper than I feared

A 40-minute consult with a real estate attorney cost $200 and produced three sentences I wrote on the back of a utility bill. One: possession is a problem regardless of whose it is, so nothing gets removed by me or my agent, ever. Two: the removal should be done by the seller, documented, ideally with a police courtesy call so the removal is itself on the record as lawful. Three: the irrigation tap into the supply line is the actual structural issue, because unpermitted modifications to plumbing in a crawlspace can hide leaks and can matter to my insurer later.

a deputy, a Saturday, and $600

The seller handled it better than anticipated once his agent laid out the alternative, which was losing the sale. He called the county sheriff's non-emergency line himself, a deputy came out and oversaw the removal over one Saturday, and the son, who by then was in Denver, paid a $600 remediation bill his father forwarded with a note that contained the word "humility."

the inspection report became a negotiation document

With the plants gone, the deal's real question was money. My inspection report now listed, beyond the botanical surprise, the residue of the operation: humidity staining on two floor joists near the ventilation duct, the patched water line that needed a proper fitting and shutoff valve, and a musty odor report from the crawlspace air. My contractor walked it with me and quoted $1,850 for the plumbing fix, replacing two suspect sections of joist sistering, and a vapor barrier refresh across 900 square feet of crawlspace floor.

I asked for the full $1,850 plus a $1,000 credit for the odor risk nobody could price. We settled at $2,300 after one testy phone call, and the seller's agent, who had spent two weeks managing a marijuana story she never signed up for, agreed mostly to make it end. My lender, when I disclosed the situation proactively with the removal documentation attached, took no issue at all. The appraiser who visited in week three saw a clean crawlspace and a receipt, valued the house at $278,000, and the whole episode cost the deal eleven days.

what mold and insurance taught me afterward

the smell that outlived the paperwork

The lingering question after closing was the smell, and I'll be honest, the first month I slept in the house I could catch a faint green mustiness thru the floor registers on humid mornings. The remediation receipt had covered removal, not air, so I spent another $740 on a commercial-grade dehumidifier run continuously in the crawlspace for six weeks and a fresh vapor barrier seam tape pass. By March the smell was gone, and the humidity readings I now check monthly have sat at 48 to 55%, which my contractor calls healthy for a crawlspace in my climate.

I also had a longer conversation than I anticipated with my insurance agent. Insurers do not love discovery of previous grow operations, cuz professional grows correlate with rewired electrical and tampered plumbing, both fire risks. My policy was issued with no issue after I provided the removal documentation, but the agent told me some carriers would have required a four-point inspection first, and a few would have declined outright til a year of clean claims history existed elsewhere. Disclosure was the difference; had the grow surfaced after binding thru a claim, I could have been looking at a rescinded policy on a house I'd just financed with a 6.6% mortgage.

the checklist for anyone else's crawl space

I now have opinions, which I will inflict on you. If your inspection report says the inspector "did not enter" any crawlspace or attic, that's a hole in your $425, and you should pay someone who goes in. Look for the boring evidence of exciting problems: fresh pipe tape where none should be, new-looking ducting in an old space, extension cords, and dehumidifiers that belong to nobody. Ask the seller directly, in writing, whether any unpermitted work exists anywhere on the property, because a written answer changes the legal posture of everything found later. And if you find something criminal, do not touch it, do not photograph it with your own hands in frame, and call a lawyer before you call anyone else, including your well-meaning brother-in-law.

My house has no plants under it now. The crawlspace hatch has a padlock, which costs $19 and closes the story every time I look at it. The deputy who oversaw the removal told me he'd seen four of these that year, and all of em were found, like mine, by somebody poking around before a sale. The poking around works. That's what its for.
