No-drill smart-home kits rented by tenants and moved to their next flat
TL;DR Unboltly rents tenants a smart-home kit that never touches the walls: a doorbell camera that clamps to the frame, stick-on door sensors, smart plugs and a shelf camera. When the tenant moves, Unboltly packs it and refits it at the new flat. Tenants pay monthly and keep their deposit safe.
About 27% of urban Indians lived in rented housing in 2011, and only around 5% of rental dwellings were let under formal agreements in the NSSO's 2008–09 estimate[1]. Tenants move often, and they hold back on anything that drills into a wall. The Model Tenancy Act caps residential deposits at two months' rent and treats structural changes made without the landlord's written consent as a ground for eviction[1].
So renters go without the security and convenience owners take for granted. Want a smart lock or doorbell? That means drilling, asking the landlord, and then leaving it behind or patching holes at move-out. Single women, students and young couples in shared flats feel this most, because they want to see who is at the door.
Unboltly sells a kit, not a gadget. Every part fits without a drill - a video doorbell on a frame clamp, adhesive contact sensors for the main door and balcony, two smart plugs, an indoor camera that sits on a shelf, and a hub. A technician fits it in about 30 minutes and photographs the walls before and after, so the tenant has proof for the deposit inspection.
The app shows who rang and when the door opened, and lets housemates share access. When the tenant moves they book a pickup, and Unboltly removes the kit and refits it at the new address, in the same city or another one it serves. Parts are refurbished and re-rented between customers, which keeps the monthly price down.
The seed works as described. I just narrowed it to the one promise renters care about - nothing that touches the walls, and nothing left behind.
The tenant pays - young professionals, students and couples in shared or rented flats in large cities. My planned price is ₹299–599 a month on a six-month minimum (assumption, untested). Furniture rental platforms, which already rent appliances and electronics[2], are a natural channel. Co-living operators could bundle the kit into rent.
Monthly rental of household goods is normal in Indian cities. One furniture-rental platform has rented since 2012 and raised US$30 million in 2016 (about ₹290 Cr)[3], and another rents across more than 20 cities with tenures from 3 to 36 months[4]. Indian smart-home brands now sell doorbells, locks and cameras outright[5], so the parts are available. The Model Tenancy Act, approved in 2021, is nudging states towards written tenancies[1].
No public figure exists for smart-home spending by Indian renters. The base is the 27% of urban residents who rented in 2011[1]. On the adjacent side, one rental platform's release puts office-chair rents at ₹150–500 a month[4], which shows urban renters accept small monthly fees for durable goods. Treat both as context.
Consumer furniture-rental platforms rent furniture and appliances but list no smart-home kits[2][3]. Smart-home brands sell smart locks, doorbells and plugs for owners to buy and install[5]. I found no Indian service that rents a smart-home kit and moves it with the tenant, though search was limited this round. The gap is the move. Today a tenant who buys devices either leaves them behind or patches the holes.
| Difficulty | Moderate (39/100) |
| Starting capital | ₹50 L–1 Cr |
| Time to launch | 4–6 months |
The devices exist. The hard part is logistics - fitting, removing and refurbishing kits across a city, and keeping loss and damage low. Churn is high because tenants move often, so the whole economics depend on each kit earning across several customers and that is no easy task.
No sector licence to rent smart-home kits, but the devices themselves need approvals.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't use AI to identify faces or track neighbours. The privacy risk is high and the tenant's consent doesn't cover people who walk past.

Here's what can go south -
I like it for an operator who has run rental or field-service logistics in a big city. If you want to design hardware then it's a weak fit. Prove first that a kit earns back its cost within 12 months, across at least two tenants, with under 5% lost.
Plan for roughly ₹50 L–1 Cr, most of it tied up in kits, fitting staff and pickups.
No sector licence, but cameras and adaptors must be BIS-registered and radio models need WPC approval. You also need the tenant's consent for camera data.
Yes, anywhere tenants move often and can't drill walls. Check local device safety approvals and privacy rules on home cameras.

Thinking about building Unboltly or something close to it? The make-or-break work is moving, refurbishing and re-renting kits cheaply enough to make each one pay, and I'm happy to run those numbers with you. If you need a hand, you know where to find me. Talk to Yash →
