The adoption table (from years of alley observation)
| Item | Alley adoption odds | The fallback |
|---|---|---|
| Anything metal (frames, shelving, grills) | Hours — the scrappers are faster than 311 | Rarely needed |
| Working tools, bikes, appliances-that-run | Same day with a "WORKS" sign | Rarely needed |
| Solid-wood furniture, clean condition | Good — better with a group post | $62–$129 flat if it sits |
| Upholstered furniture | Weather lottery — rain beats adopters | Sofa $126, carried from inside |
| Particleboard anything | Poor — it can't survive the move | Desk $83, bookshelf $72 |
| Mattresses | Never. Nobody. Ever. | $82–$114 by size |
| CRT TVs | Never — and banned from disposal anyway | The e-waste routes |
The legality overlay (the part folklore skips)
A curb alert is still a set-out: your building, your timing, your ward — the three-part alley test applies whether the sign says FREE or not. Black-cart buildings placing beside the cart around collection timing are playing the game as designed; big-building tenants borrowing an alley are fly dumping with optimism. And the weather rule doubles as the ethics rule: if rain arrives before an adopter, bring it back in — a soaked free pile is dumping with extra steps.
The 48-hour rule
The alley economy votes fast. If your item survives two days and one weather forecast, it has been declined — further waiting just weathers it into unadoptability and your address into a complaint. The workflow that respects both economies: set it out legally, post it to the groups, calendar a reminder for 48 hours — still there Thursday means book Thursday. Most single items run $100–$186 flat, carried from wherever the item retreated to.
Frequently asked questions
Do curb alerts work in Chicago?
For the right items, remarkably well — Chicago's alley economy adopts metal, tools, working electronics-adjacent gear, bikes, and decent solid-wood furniture within hours, especially with a 'FREE / WORKS' sign and a post to a neighborhood group. The catches: the legality overlay (your building and timing still have to pass the alley test), weather (one rain converts 'free couch' to 'ruined couch'), and adoption bias — what YOU want gone and what the alley WANTS are different lists.
What never gets taken from a Chicago free pile?
Mattresses lead the never-adopted list — nobody scavenges used bedding — followed by wet or stained upholstery, particleboard furniture (it doesn't survive the move), CRT televisions (banned from disposal and worthless), and anything broken that isn't metal. Those items don't need a sign; they need a route: flat pickup (mattress $111–$114, sofa $126) or the 311 system where eligible.
How long should I give a curb alert before booking a pickup?
48 hours is the honest window — the alley economy moves fast or not at all. If the item survives two days and one weather forecast, it's been voted on. Set a calendar reminder when you set the item out: still there Thursday means book Thursday ($100 minimum, most single items $100–$186 flat).
What makes a curb alert work best in Chicago?
The formula: legal placement (your building, your timing, beside your cart), a sign with the one fact that matters ('WORKS' or 'CLEAN — NO PETS'), a photo posted to the neighborhood groups, and dry weather in the forecast. And take the item back in if rain arrives — a ruined free pile is just fly dumping with extra steps.
