There's no guaranteed dollar-for-dollar return
Unlike a kitchen remodel with well-tracked resale data, standby generators don't have a standardized "percent of cost recouped" figure the way major renovations sometimes do. Buyer interest varies a lot by region and how outage-prone the local area is.
Where it tends to matter most
In areas with frequent storms, wildfire-related utility shutoffs, or an aging grid, a working, well-maintained standby generator can be a genuine differentiator for buyers — sometimes mentioned specifically in listings. In areas with reliable utility service, it may register as a nice-to-have rather than a deciding factor.
Condition and documentation matter
A generator with maintenance records and a clean permit/inspection history reads very differently to a buyer (or their inspector) than an undocumented unit of unknown age and service history — this is a good reason to keep maintenance records from day one.
A possible insurance angle, separate from resale value
Some homeowner's insurance providers offer modest premium credits or discounts for a permitted, professionally installed standby generator, treating it as a risk-reduction feature similar to a security system — though this varies significantly by insurer and isn't universal. It's worth asking your provider directly rather than assuming a discount applies.
