Onda’s PH4 illustrates why a penthouse budget must extend beyond the advertised association charge. Its reported HOA and tax subtotal is $274,529 annually, before separately payable services and other ownership costs.

A penthouse should make ownership feel effortless. Its due-diligence file should show exactly what that effortlessness costs. For a Bay Harbor Islands buyer, the essential distinction is between maintaining the condominium and maintaining a private residence to the owner’s preferred standard. Those remain separate budgets unless written agreements establish otherwise.
At Onda Bay Harbor, PH4 offers a useful starting point. The residence is at 1135 103rd St, Bay Harbor Islands, FL 33154, with a reported construction year of 2024. Its reported monthly maintenance/common charges are $10,315, or $123,780 annually.
The reported annual property tax is $150,749. Together, these figures yield a $274,529 annual subtotal. That is not the complete annual carry, nor is the tax figure a verified projection for an incoming owner. Separately payable insurance, utilities, unit management, housekeeping, gratuities and repairs remain outside the calculation.
The next step is not to add an arbitrary percentage for everything else. It is to build an ownership budget in which every recurring expense has an identified payer, scope and billing frequency. Leave unpriced items visibly unresolved rather than quietly treating them as zero.
Even within one address, the penthouse label does not establish a common fee. Penthouse 3 has a reported monthly HOA charge of $8,754, equivalent to $105,048 annually. PH4’s charge should therefore not be applied across the building’s penthouses.
Other reported figures reinforce the point: Unit 602 carries $4,400 monthly; Unit 203, $4,689; Unit 403, $7,627; and Unit 504, $8,737. These figures reflect different dates, not a synchronized or association-certified fee schedule. They demonstrate variation without establishing why the allocations differ.
For buyers also considering Bay Harbor Towers, the useful comparison is a residence-specific schedule of charges and inclusions. Request the same documents for each candidate. A lower headline fee is meaningful only once you establish which expenses fall outside it and whether the figures cover the same budget period.
Onda’s reported amenities include a fitness center, marina, pool and spa/hot tub. Their presence describes the building’s offering; it does not establish that every associated use or private service is included in a particular unit’s monthly charge.
Water for PH4 is reported to be covered by its HOA fee. Unit 403’s reported inclusions extend to common areas, grounds and structural maintenance, sewer, security, trash and water. Treat those inclusions as a prompt for questions, not a substitute for PH4’s own documents.
In-unit housekeeping does not appear among Unit 403’s reported inclusions. That omission neither confirms availability nor establishes a price. Ask for a written distinction between common-area cleaning and cleaning inside the residence.
Apply the same discipline to a comparison with Alana Bay Harbor Islands: identify what the association provides, what an owner may arrange independently and what, if anything, requires a separate service agreement.
A unit-management agreement should answer a different question from the association budget: who takes responsibility for the residence when the owner is absent? Before seeking a quote, specify the work. Possible requests include scheduled inspections, vendor access, maintenance coordination, arrival preparation and emergency response. These are proposed contract terms, not confirmed Onda services.
No Onda-specific unit-management fee schedule is established here. Request a written proposal that separates any recurring retainer from visits, callouts, project supervision and reimbursable expenses. Define spending authority and the circumstances requiring owner approval.
Do not assume income-based management pricing meets the needs of a privately occupied second home. Ask how the arrangement operates during periods without rental income and whether it covers non-rental oversight at all.
Finally, separate service availability from rental eligibility. Onda’s minimum lease term and short-term-rental permissions remain unconfirmed here. Verify both independently before including rental income in the ownership model.
Housekeeping can be budgeted once the scope is clear. Request separate quotes for routine visits, pre-arrival preparation, departure cleaning and any deeper cleaning the owner expects. Define whether laundry, supplies and exterior living areas are included, and ask about minimum visits, cancellation terms and access arrangements.
An annual housekeeping estimate should follow the intended calendar: agreed visit prices multiplied by planned visits, plus separately quoted extras. Without that schedule, a monthly allowance can look precise while describing very little. No Onda-specific housekeeping rate is established here.
Gratuities require equal clarity. No Onda-specific mandatory service charge or gratuity schedule is established. Ask whether each vendor’s invoice includes a service charge, whether any tipping policy applies and which payments are discretionary. Do not assume a service charge and a gratuity are interchangeable.
Keep contractual charges and voluntary gratuities on separate lines. That distinction makes the budget easier to reconcile and prevents an assumed tipping percentage from becoming an unsupported statement about the building’s costs.
The closing file should translate reported figures into current, unit-specific obligations. Request the unit’s current estoppel, adopted association budget, reserve schedule and special-assessment information. Reconcile the reported monthly charge with those materials and clarify any additional amounts, payment dates or obligations that affect the purchase.
Insurance needs a separate review. Obtain a unit-specific owner-policy quote and confirm the master policy’s coverage and the owner’s responsibilities. Do not assume the stated association payment settles either the scope or cost of the owner’s insurance.
Property taxes deserve their own underwriting line. Use the reported $150,749 figure as a reference, then obtain a buyer-specific estimate rather than carrying it forward unchanged. The incoming owner’s eventual bill remains unconfirmed.
For utilities, confirm which services are included and obtain estimates for those payable separately. Water’s stated inclusion in PH4 should not become a blanket assumption about electricity, communications or other expenses.
Keep potential special assessments and irregular repairs visible alongside recurring expenses. Avoid counting an association reserve contribution twice if it is already reflected in the confirmed dues.
The finished schedule should distinguish confirmed recurring obligations, quoted private services, discretionary spending and unresolved exposures. Begin with the reported HOA and tax subtotal, then replace those inputs as current documents and buyer-specific estimates become available. Add separately payable costs without double counting included services.
If the purchase is financed, show debt service separately to keep property operating costs distinct from total annual cash requirements. The figures above do not account for financing costs.
The objective is not a reassuringly tidy number. It is an ownership plan that supports spontaneous arrivals and extended absences without leaving responsibilities undefined.

No; it is the calculated subtotal of reported HOA charges and property tax, before separately payable insurance, utilities, private services, gratuities and repairs.
The reported figure is not a verified projection for a new owner. Obtain a buyer-specific tax estimate before finalizing the budget.
The reported charges differ: Penthouse 3 is $8,754 monthly, compared with PH4’s $10,315. These figures are not a synchronized, association-certified schedule.
Water for PH4 is reported to be included in its HOA fee. Confirm that inclusion in the current unit-specific documents.
In-unit housekeeping is absent from Unit 403’s reported HOA inclusions. That does not establish PH4’s service coverage, housekeeping availability or pricing.
Request defined responsibilities, visit frequency, emergency response terms, spending authority and separate charges. No Onda-specific unit-management tariff is established here.
No Onda-specific gratuity schedule or mandatory service charge is established. Ask for written policies and distinguish contractual charges from voluntary payments.
Request the current estoppel, adopted budget, reserve schedule, special-assessment information, insurance responsibilities and written service rate sheets. Obtain a unit-specific owner-policy quote as well.
Not without separately confirming rental permissions and the applicable economics. Onda’s minimum lease term and short-term-rental eligibility remain unverified.
