St. Johns County gives ALF buyers something I wish every county made this clear: resident capacity is built into the local Special Care Housing framework. That means the zoning conversation should start with the number of residents you plan to serve, not with a generic statement that the property will be an assisted living facility.

This is especially important because the county changed its Special Care Housing rules in 2024. I would not rely on an older property example or assume that a residential-looking building follows the same approval lane at six residents, fourteen residents, and fifteen or more residents.

Know Which Special Care Housing Level You Are Actually Proposing

St. Johns County categorizes assisted living and related residential-care uses under Special Care Housing. The county amendments identify Level I for six or fewer residents, Level II for seven through fourteen, and Level III for fifteen or more. Those levels affect where the use can be located and whether a special-use process is involved.

The county publishes its current Land Development Code online, and the official 2024 Special Care Housing amendment report explains the capacity-based framework. I would identify the level before making an offer on the property.

Spacing Can Still Change a Property Decision

A 2026 county application record involving Special Care Housing shows how seriously proximity can matter: staff flagged other homes within 1,000 feet while reviewing a request related to spacing. That does not mean every project follows the same procedure, but it is a good reminder that parcel-specific proximity should be checked early.

Environmental Health Needs the Real Kitchen Plan, Not a Concept

The St. Johns material provided to my team is primarily Environmental Health correspondence. The local office asked for a completed plan-review application and an accurate scaled food-service floor plan. The review depended on resident count and the size and number of food-operation areas.

The correspondence also described an on-site construction inspection after plan approval and sufficient build-out, before the opening inspection. I would not wait until the kitchen is finished to discover that the layout does not match the approved plan.

The Public CEMP Instructions Are Not Detailed Enough to Guess

St. Johns County publishes broad Emergency Management resources, but I did not find a current public ALF-specific intake page detailed enough to treat as a complete submission guide. I would confirm the current healthcare-facility CEMP contact, submission method, fire-plan expectations, and supporting documents directly before filing.

Settle the Level Before the Floor Plan

Level I, Level II, and Level III each carry different location and approval consequences, so I would pick the level first and design second. A six-bed home and a fifteen-bed facility are not the same building with a different number on the door. Ask Planning, in writing, which level your proposal falls under on the parcel and what process comes with it. Then draw the plan. Reversing that order, and learning later that the level does not fit the property, is one of the more expensive mistakes I can imagine here.

Keep Proximity on Your Checklist

Spacing came up in a 2026 application record where staff flagged other homes within 1,000 feet. That is a useful reminder, not a rule for every project. I would run a proximity check on any parcel before an offer, ask Planning how they measure distance and which uses count, and keep a dated copy of the answer. If something is close, you want to know what the county will do about it while you can still walk away, not when the application review brings it up.

Build the Kitchen the Health Office Approved

Environmental Health asked for an accurate, scaled food-service floor plan and described an onsite construction inspection after plan approval. The practical takeaway is simple: build what was approved. If the contractor wants to move a sink, add a prep area, or change a wall, stop and check first. Small changes made for convenience can send you back through review. Give a copy of the approved plan to every trade, and treat any change as a question for the health office, not for the contractor.

My St. John's Rule: Capacity Is a Land-Use Decision

The difference between six, fourteen, and fifteen residents is not just a licensing or revenue decision here. It can change the local land-use category and approval intensity. I would answer that question before designing the building around a bed count the zoning cannot support.

Before moving forward, review our How to Open an ALF in Florida guide and our Florida ALF zoning requirements resource so the property decision and the licensing plan are working together.
