A disciplined framework for evaluating a replacement residence, tracking qualifying rental use, and managing the family, guest, and staff arrangements that can complicate a tax-deferred exchange.
For a family office acquiring a South Florida residence through a tax-deferred exchange, the decisive question is not simply whether the property can attract a tenant. It is whether the planned occupancy supports investment use and complies with the residence's rental restrictions.
An extended family visit, a house manager's overnight presence, or a complimentary stay can complicate that analysis. Owner absence is not a substitute for qualifying use. The acquisition brief should separate three decisions: whether the residence permits the intended rentals, whether the proposed use fits the dwelling-unit safe harbor, and how every stay will be documented.
These are distinct inquiries. Satisfying the safe harbor protects the investment-or-business holding purpose; it does not independently establish compliance with every §1031 requirement. Treat this checklist as a planning framework to review with exchange and tax advisers, not as a transaction-specific tax opinion.
Architectural appeal and exchange suitability are separate considerations. Before committing, request the applicable condominium or HOA documents and confirmation of relevant zoning and licensing requirements. Ask specifically about minimum lease terms, rental frequency, tenant approvals, guest registration, and staff occupancy.
For a Brickell search that includes Una Residences Brickell, the underwriting file should establish whether the exact proposed rental schedule is permissible. A general description of the residence as rentable is not enough.
Apply the same discipline to a Miami Beach review involving The Perigon Miami Beach. Neither project reference establishes rental permission or exchange suitability. Obtain property-specific confirmation before treating either as a candidate for the intended strategy.
Make documentary clarity an acquisition condition: the operating plan should not depend on an unconfirmed exception to building rules.
For a replacement dwelling to fall within the safe harbor, ownership must continue for at least 24 months immediately after the exchange. Within each of the two qualifying 12-month periods:
The dwelling must be rented to another person at fair-market rent for at least 14 days.
Personal use must not exceed the greater of 14 days or 10% of the days rented at fair-market rent.
These periods follow the exchange, not necessarily calendar tax years. Establish their opening and closing dates at acquisition, and maintain separate running totals for each.
For illustration, 100 qualifying rental days produce a 14-day personal-use ceiling; 200 produce a 20-day ceiling. Days merely advertised or available for rent do not increase the percentage-based allowance. Rental days in one period cannot offset a shortfall in the other.
The 24-month rule belongs to this safe harbor. It is not a universal statutory holding-period requirement for every §1031 exchange, and falling outside the safe harbor does not, by itself, determine exchange treatment.
An occupancy policy should identify who is staying, their relationship to the owners, what they are paying, and the purpose of the stay. Duration alone does not determine treatment.
Use by the taxpayer or another person with an ownership interest generally counts as personal use. Family occupancy generally does too, subject to an exception when the family member pays fair-market rent and uses the property as a main home. A market-rate family vacation booking does not, by itself, satisfy that exception.
Friends and other guests staying free or below market generally generate personal-use days. Reciprocal home-use arrangements also count as personal use, even when rent is involved. By contrast, unrelated guests paying fair-market rent can supply qualifying rental days if no other personal-use rule applies.
In Coconut Grove, a buyer considering Park Grove Coconut Grove should resolve the intended family-access policy alongside the property review-not after invitations have been extended. This is a governance recommendation, not confirmation of that project's rental rules.
A live-in manager may serve an operational purpose, but employment status does not establish a blanket exemption from personal-use treatment. Nor should a family office assume that describing housing as convenient for the employer resolves its treatment under §280A.
Before approving overnight occupancy, prepare a written staffing file covering operational duties, occupancy terms, designated quarters, work schedules, and owner or family access. Address whether the manager's family may stay and whether the housing arrangement changes during owner visits or tenant occupancy.
Ask tax advisers to evaluate housing compensation and day-count treatment against those facts. These records are recommended controls, not additional established safe-harbor requirements.
A separate bedroom or designated staff suite is not an automatic tax shield. Document the arrangement and obtain advice before classifying those nights in the occupancy ledger.
The owners can be overseas while the residence still accumulates personal-use days through family visits or below-market guests. A travel calendar cannot replace an occupancy calendar.
For a Surfside candidate such as Ocean House Surfside, make access administration part of diligence without assuming any particular building policy or staffing arrangement.
Recommended controls include written booking agreements, market-rent support, payment records, and advance approval for family stays. Assign one family-office decision-maker to approve exceptions, and instruct staff not to promise complimentary accommodation independently.
Maintain a centralized calendar recording actual arrivals, departures, occupants, relationships, rental charges, and unresolved classifications. Supporting access records can help reconcile occupancy, but do not alone establish its tax treatment. Review the ledger quarterly against each qualifying 12-month period rather than waiting for year-end reporting.
Entity ownership does not remove personal-use concerns. Partnership or S-corporation structures can involve attribution of relatives' use to partners or shareholders, so the review should extend beyond the person named on a booking.
Mixed rental and personal use can also require expense allocation and limit rental deductions under rules separate from exchange eligibility. Schedule E reporting, by itself, does not establish qualifying investment use.
Maintain three distinct conclusions in the file: property-level rental permission, the exchange qualifying-use analysis, and annual rental tax treatment. Together, they create a more defensible operating framework than a single label such as investment residence.
Before proceeding, the family office should approve the rental-permissions file, both qualifying-period calendars, a guest policy, a staff-occupancy review, and responsibility for quarterly reconciliation. Refer unresolved classifications to advisers before promising accommodation.
The most useful luxury is predictability: a residence whose permitted use, family access, and management arrangements have been considered together.

No. The replacement dwelling's 24-month ownership requirement belongs to this safe harbor, not a universal statutory holding-period rule for every exchange.
The dwelling must be rented to another person at fair-market rent for at least 14 days in each of the two qualifying 12-month periods following the exchange.
In each qualifying 12-month period, the ceiling is the greater of 14 days or 10% of actual fair-market rental days. Merely advertising the residence does not increase that allowance.
Not automatically. They are the two 12-month periods following the exchange, so the operating calendar should track those periods separately.
No. The family-use exception generally requires both fair-market rent and use of the dwelling as the family member's main home.
No. Family occupancy and free or below-market guest stays can generate personal-use days even when the owner is elsewhere.
No blanket exemption should be assumed. Document duties, housing terms, designated quarters, and access, then obtain advice on compensation and day-count treatment.
No. Partnership or S-corporation ownership can involve attribution of relatives' use to partners or shareholders.
No rental permission or exchange suitability is established by a project reference. Verify applicable zoning, licensing, and condominium or HOA restrictions for the intended occupancy plan.
