This market, from the inside
One honest caveat: these fields are agent-entered, so a home with a genuine in-law setup occasionally goes untagged — the count here is a floor, not a ceiling. If you’re after a specific configuration (full kitchen, private entrance, first-floor), say so and Krista will screen the shortlist against the floor plans.
Frequently asked questions
What counts as an in-law suite in these listings?
The MLS feature fields behind this page cover three setups: an in-law suite inside the home (typically a bedroom with en-suite bath and often a kitchenette), a guest-suite wing, or a detached guest house on the lot. The listing details and floor plan confirm which one a specific home has — configurations vary widely, so verify the specifics that matter to you.
Do new-construction builders in St. Johns County offer in-law suite floor plans?
Yes — several builders active in the county offer multi-suite plans (often marketed as “next-gen” style layouts with a separate entrance and living space). If nothing on the resale market fits, the new-construction communities are the other path — and bringing your own agent to the builder costs you nothing.

I’ll send new listings the moment they hit the market and walk through the details that don’t show up in the MLS — water access, HOA rules, what a feature really costs to maintain.
