Our tanks are about 10 years old and many in our HOA are discussing replacing them to avoid in-house water damage.

Our two 50-gallon tanks are daisy-chained, so they don't serve different parts of the house. It's like one big tank.

While looking at tanks, we see individual 60 and 70 gallon tanks that are rated to serve a family of 5 (two adults and three kids). But the estimates we have received are solely to replace what we have with the same thing.

Installation of one tank, and operational costs through the year, would be far lower with one tank as opposed to two. Are there guidelines with regard to using one larger tanks instead of two?

The International Residential Code and International Plumbing Code do not provide standards for the determination of a minimum size for water heaters in a residence. That decision could be made on your personal needs, lifestyle and convenience. For example, if you have a large Jacuzzi style tub the capacity of a smaller heater may not be enough to fill it, so that would be a something to consider in your decision. Many manufacturers have tools on their websites to assist in determining what product would best suit the customers needs.
Most contractors would probably quote replacement of one larger heater at your request. Another option would be replacement with a tankless heater.
