Quick answer
A renter’s “best” thermostat is the one your lease allows. With written landlord permission and typical wiring, start with the Google Nest Thermostat (around $130 as of Oct 23) — Google notes most homes do not need a C-wire. Want Ecobee sensors/HomeKit? Budget Premium/Enhanced (adapter often in-box) or Essential + kit (~$135), but know ecobee’s adapter usually installs at the furnace, which many landlords treat as off-limits without an HVAC tech. Skip the Amazon Smart Thermostat unless you already have a C-wire — it requires one. No permission? Do not replace the wall plate.

How we researched this
Prices checked Oct 15, 2026, plus the research behind our Ecobee vs Nest comparison (Wirecutter, Tom’s Guide), the ecobee Smart Thermostat Enhanced page, and Google’s Nest Thermostat page. Research-based only. We have not installed these thermostats.
Landlord rules first
- Ask in writing before removing the existing thermostat.
- Photograph wiring and keep the original thermostat to reinstall at move-out.
- Furnace-closet adapters (ecobee PEK-style kits) touch equipment outside the living space — call that out when you ask.
- No permission → no wall swap. Space heaters should not go on smart plugs at all; plug them directly into a wall outlet, as the CPSC advises.
Best budget pick when allowed: Nest Thermostat
About $130 (as of Oct 23). Strong renter candidate because Google says most homes don’t need a C-wire, so you avoid adapter drama. Fewer sensors than Ecobee or Nest Learning — fine for studios and one-zone apartments. Google Home / Assistant native.
When Ecobee still makes sense
If the landlord OK’s a full install (and furnace access if needed), Ecobee’s SmartSensors and HomeKit path match our main comparison. Premium (around $260 as of Oct 18) is the comfort pick; Essential + kit is cheaper but more dependent on that adapter conversation.
What to skip
- Amazon Smart Thermostat without a confirmed C-wire.
- Any install that cuts or permanently alters landlord HVAC wiring.
- Buying Learning 4th gen (around $280 as of Oct 22) for a short lease unless you will take it to the next place and the landlord agrees.
Buying guide for renters
- Get permission first.
- Prefer no-C-wire or in-living-space-only installs.
- Match the assistant you already use (see hubs for beginners).
- Plan the move-out restore.
- Cross-read Ecobee vs Nest before paying for Premium features you will not keep a year.

Frequently asked questions
Can renters install a smart thermostat?
Only with landlord permission if you replace the wall thermostat. The safest path is written OK plus a reversible install that restores the original unit at move-out. Furnace-closet power adapters (common with ecobee kits) may also need approval because they touch HVAC equipment outside the living space.
What is the best smart thermostat for renters on a budget?
If you have permission and most homes’ wiring, the Google Nest Thermostat (around $130 as of Oct 23) is the strongest budget pick we found — most installs do not need a C-wire. Skip the Amazon Smart Thermostat if you lack a C-wire; it requires one.
Do I need a C-wire as a renter?
Many Nest models work without a C-wire in most homes. Ecobee Premium/Enhanced often include an adapter kit that installs at the furnace — helpful technically, but that furnace work is exactly what many leases restrict. Essential needs a C-wire or the kit.
What if my landlord says no?
Do not swap the thermostat. Don't put a portable space heater on a smart plug; the CPSC advises plugging space heaters directly into a wall outlet. A smart plug can still schedule a fan within its rating, or you can negotiate a landlord-owned Nest/ecobee install. Never cut HVAC wires without approval.
