Refinishing hardwood floors is a great way to add value to a home, but the process involves industrial drum sanders that create a deafening roar and intense vibration. If you (or your neighbor) plan to tackle this as a weekend DIY project, you need to know the rules.
Why Floor Sanding is Different
Floor sanding combines two types of noise annoyance:
- High Decibels: The machine itself is loud, often requiring ear protection for the operator.
- Structural Vibration: The drum grinds directly against the subfloor, turning the floor into a giant speaker cone that broadcasts vibration into the unit below.
Because of the vibration, this is often considered "construction activity," not just normal household noise.
Weekend Restrictions
Most cities and HOAs restrict construction noise on weekends.
- Saturdays: Often limited to 9 AM - 5 PM.
- Sundays: Frequently prohibited entirely.
Even if your city allows Sunday DIY, operating a drum sander in a multi-unit building on a Sunday is widely considered a violation of the "quiet enjoyment" clause in a lease due to the severity of the disturbance.

Best Practices for DIYers
If you are the one sanding:
- Notify Neighbors: Tell the unit below you exactly when you will be starting and stopping.
- Rent the Right Gear: Modern orbital sanders are often quieter (and easier to use) than belt sanders.
- Stick to Mid-Day: Do the heavy sanding between 10 AM and 4 PM. Save the quieter edging work for earlier or later.
The Takeaway
Floor sanding is one of the loudest renovations possible. Treat it as major construction, respect weekend restrictions, and communicate with your downstairs neighbor to avoid a noise complaint stopping your project halfway through.
