The 7-Point Pinellas Buyer Checklist

Run this list on every address before you write an offer.

  1. Jurisdiction and zoning. Confirm city vs unincorporated on the Pinellas County Property Appraiser site. Setbacks and allowed uses depend on it.
  2. FEMA flood zone and base flood elevation. Look it up on the FEMA Flood Map Service Center or use the live Pinellas flood zone tool. Save the panel.
  3. Property lines and easements. Use free Pinellas GIS first. Order a survey when lines are unclear, fences are missing, or you plan additions.
  4. Deferred maintenance and inspection flags. Roof age, HVAC, plumbing, electrical, and foundation. Full checklist in the linked deferred maintenance guide.
  5. Insurance and wind mitigation. Get flood and wind quotes written for the actual use. Premiums affect offer price.
  6. HOA or condo documents and reserves (if applicable). Review budgets, reserves, and any rental or use restrictions.
  7. Closing and title items. Survey, open permits, liens, and seller disclosures.

Flood Zones Deep Dive

The highest-impression guide on the site covers this in detail: Pinellas County Flood Zones: The Complete Guide for Home Buyers.

Key points to confirm before offer:

  • Zone AE, VE, or X
  • Elevation certificate (if available)
  • Substantial improvement threshold (49% in unincorporated Pinellas)
  • Evacuation zone (separate from flood zone)

Property Lines Deep Dive

Free first step: How to Find the Property Lines of Your Pinellas County Home.

Use the county GIS viewer. Order a boundary survey when:

  • You plan a pool, addition, or fence
  • Neighbor fences or structures look close
  • The listing description and appraiser map disagree

Deferred Maintenance Flags

See the full list in Buying a Tampa Bay Home: Deferred Maintenance Checklist (buyer version).

Common Pinellas issues: older roofs, galvanized plumbing, outdated electrical panels, and moisture in coastal properties.

Maps, codes, and insurance rules change. Confirm each item with the local floodplain office, a licensed surveyor, your inspector, and your insurance agent for the exact parcel. This is educational, not legal or insurance advice.
