429 30th Street, West Palm Beach, FL 33407

Significance

The house stands in Northwood, a subdivision platted in 1921 by the Pinewood Development Company, whose principals the National Register nomination names as David F. Dunkle, Orrin Randolph, and G. W. Bingham. The nomination's building inventory lists 429 30th Street as a residence of 1925 in Mediterranean Revival style, together with a rear garage apartment of the same year, and both fall within the nomination's list of contributing buildings. The nomination's narrative describes the house as a two story stucco residence whose entrance is recessed in a small arched opening, with French doors above it opening onto a small balconet with a wrought iron railing. The Palm Beach County Property Appraiser records the year built as 1926, one year later than the nomination, and the discrepancy is unresolved in the sources reviewed. No architect, builder, or original owner is identified for this address in the nomination or in any other source reviewed.

Buyer diligence

• Confirm with the City of West Palm Beach Historic Preservation Board whether a certificate of appropriateness is required before any exterior work, and what the review timeline looks like.
• Ask the City of West Palm Beach whether its historic property ad valorem tax exemption for qualifying rehabilitation may apply to planned work, and on what terms.
• Confirm the contributing status of this specific address against the National Register nomination inventory rather than relying on the district boundary alone.
• Confirm the year built with the Palm Beach County Property Appraiser and reconcile the county's 1926 against the nomination's 1925, using permit or building records rather than either secondary account.
• Reconcile the 5 bedrooms and 5 baths given in listing material against the county record for the main structure, which shows 4 bedrooms and 3.5 baths, and establish whether the rear garage apartment is counted in either figure.
• Pull the current FEMA flood zone designation and an elevation certificate for the parcel.

What the record cannot show

• The architect, the builder, and the original owner of the house, none of which were identified in the National Register nomination or in any other source reviewed.
• The beneficiaries behind the Mario Christopher B 2012 Family Trust, or whether the August 2025 re-titling changed beneficial ownership at all.
• The scope or quality of any renovation work, and whether any of it was carried out without permit. No permit history was reviewed.
• Whether the $3,475,000 asking price bears any relation to the consideration a completed sale would record.
