Converting a single-family home into a co-living property is more involved than turning the key over to a long-term tenant. It's also less involved than a full gut renovation. There is a specific sequence of decisions that, done well, produces a clean, profitable, code-compliant shared-housing property in 30–60 days. Done poorly, it produces a money pit. Here is the sequence.
Not every house should become a PadSplit. The two non-negotiables: enough usable bedrooms after conversion to make the math work, and an acceptable bedroom-to-bathroom ratio. The rough rule is no more than three members per bathroom. Two-and-a-half bathrooms gets you to seven rooms comfortably. One bathroom maxes out at three rooms — at which point the math is probably worse than a traditional rental.
Other red flags: tight or single-egress floor plans, no central HVAC, electrical panel that can't handle additional load (you'll be running more devices than the home was built for), and any property in a municipality with active anti-rooming-house enforcement. Check zoning before you buy.
Most conversions add at least one bedroom — typically converting a dining room, formal living room, or oversized den into a private bedroom. A code-conforming bedroom needs:
Bedroom builds are usually framed walls, drywall, paint, and a door. Budget $2,500–$5,000 per added bedroom depending on whether electrical and HVAC work are needed.
Each bedroom needs a private lock that the operator can rekey remotely when a member moves out. Smart locks with PIN codes work best. The exterior door of the house also needs to be a smart lock — never share physical keys with members.
Budget $80–$150 per smart lock. Pick one brand and stay with it for fleet maintainability.
Each bedroom needs: bed, mattress, dresser, side table, lamp, small trash can, hangers, and a window covering. Common areas need: couch, TV, dining table, small kitchen table or breakfast bar, basic cookware and dishware, two trash cans (kitchen + general), a washer and dryer, and reliable cleaning supplies storage.
Budget $1,800–$2,800 per bedroom plus $2,500–$4,000 for shared spaces. Use durable, easy-to-clean furniture. Don't buy designer pieces.
The single most important piece of infrastructure in a PadSplit is the internet. Buy the highest speed package available in your market. Place the router centrally. Add a mesh extender if the home is over 1,800 square feet. Internet that drops is the #1 driver of member complaints and early move-outs.
Utilities: set up water, electric, and gas in the operator's name. Add the cost to your monthly underwriting. Do not try to bill back utilities to members — it creates conflict, breaks the platform model, and you will lose more than you save.
Working smoke detectors in every bedroom and every common space. Working carbon monoxide detectors on each floor. A fire extinguisher in the kitchen. Posted emergency exit information. A first aid kit in a known location. Local rooming-house or co-living permits if your municipality requires them. Some markets require an inspection before listing — check first.
Walk the house as if you were a new member arriving for the first time. Are the floors clean? Are the walls touched up? Does every room have a working light? Is the bathroom mirror clean? Are the smoke detectors not chirping? Is there toilet paper in every bathroom? Is the trash empty? Is the welcome packet on the bed? This is the difference between a property that fills in two weeks and a property that sits.
Hire a real photographer. Bright, wide, clean photos of every bedroom, every common area, the kitchen, and the exterior. The listing photos are what determines your fill rate. Cheap phone photos cost you weeks of vacancy.
A typical four-to-five bedroom conversion runs $18,000–$35,000 all in — bedroom builds, smart locks, full furniture package, internet setup, compliance, and the first pass of cleaning. Lower if you're house-hacking and already have some of the infrastructure. Higher if you're starting from a totally empty shell.
