You need to reach out to an agent in the Reno/Sparks area to help you with this property inquiry. There will be some tax record research needed on the local level.
Yes, there are 1/2 duplexes for sale. You would still share a wall and the roof with your neighbor but you can definitely buy 1/2 of a duplex. I am a broker here in Northern Nevada and would be happy to help!
Yes, you can buy half of a duplex and still have full ownership of your unit, depending on how the property is titled. Duplexes can be deeded as one parcel (shared ownership) or as two separate legal lots (each with its own title). If the duplex is already divided, you can own your half outright. If not, you’d need to work with a real estate attorney or title company to establish a new legal description and ownership agreement. In Florida, this is common when investors or families purchase side-by-side units. Always confirm zoning, title, and HOA rules before you buy.
Buying one side of a duplex is possible, but you need to make sure the property has been legally subdivided so that each unit has its own parcel number and deed. In some markets duplexes are sold as a single two‐unit property; in order for each owner to hold title to their own half, the owner must record either a "condominium" declaration or a "zero‐lot‐line"/townhome plat that splits the building and land into two lots with shared walls. This also typically creates an HOA or maintenance agreement to address the common wall and shared roof.
If the duplex hasn't been legally split, you can only buy an undivided interest in the whole property, which isn't what most buyers want. Converting a duplex into two separate titles requires surveys, legal descriptions and municipal approval, so it has usually already been done when you see a "half‑duplex" listed. Your best bet is to work with a local agent in Reno/Sparks who can search the MLS for half‑duplex or townhome listings and verify that each unit has its own APN and title. They can also guide you on values, financing and what sort of shared maintenance agreements are typical in Nevada.
As a Massachusetts agent I can’t provide specific listings in Nevada, but a Nevada Realtor can search for them and may know of off‑market opportunities. Be sure to consult a real estate attorney or title company to understand the legal structure before making an offer.
