What will this home really cost you?

Building structural health (SIRS)

No filing record found

We couldn't find a SIRS filing record for this building in Florida's public DBPR database. That is not a red flag by itself: buildings under three stories are exempt, recent or mailed-in filings may not appear yet, and the name or address on file may differ from this listing.

Questions about this

What is a SIRS and why does it matter?

Since the Surfside collapse, Florida requires condo and co-op buildings three stories or taller to complete a Structural Integrity Reserve Study: an inspection-based plan that forces the association to fund structural repairs (roof, load-bearing walls, plumbing, electrical) instead of deferring them. It matters because underfunded buildings are the ones that surprise owners with large special assessments.

Has this building filed its SIRS?

We didn't find a filing record for this building in the DBPR's public database. Absence of a record does not mean the building is out of compliance — it may be exempt (under three stories), the filing may be recent or on paper, or the recorded name/address may differ. It IS the right question to ask before offering.

What is a special assessment?

A one-off charge the association levies on every owner when reserves don't cover a needed repair — in older coastal buildings they have ranged from a few thousand to over $100,000 per unit. The SIRS exists precisely to make these predictable and funded in advance. Always review the building's budget, reserves and meeting minutes before buying.

What should I check before buying in this building?

Florida law gives buyers the right to review the association's SIRS, milestone inspection reports, budget and reserves — the full study is available from the association by written request. Nilyan requests and walks through these documents with her buyers as part of the offer process.

Source: Florida DBPR public SIRS reporting database. Filing status is self-reported by the association; this is not an audit, inspection or safety certification, and absence of a record does not mean non-compliance. Data as of July 30, 2026.
