If by first floor in-law suites you are speaking of homes with a first floor master suite, then the answer is yes. Typically we do not refer to these homes as having an in-law suite, that designation is usually reserved for the lower level, i.e. basement or terrace level. You can certainly find homes with a first floor master suite for in-laws and have other bedrooms on the second level or on the lower level allowing everyone their space. I can e-mail appropriate listings if you wish.
