Before You Buy a Coral Gables House to Rebuild, Look Up Its Historic Letter

On September 17, 2026, the owner of 314 Cadima Avenue spoke at a meeting of the Coral Gables Historic Preservation Board. He told the board he had lived in the house for more than ten years, loved its history, and hoped to add one more room. City staff had already researched the property. The 1925 cottage was designed by architect H. George Fink and built by the Hopkins and Nichols team in Merrick's Coconut Grove Section. The board voted 7–0 to make it a local historic landmark.

The owner did not oppose the designation, and the meeting recording shows a friendly hearing. A single letter from the city's Historic Preservation Officer started the process, and the hearing took place eight weeks after that letter. If you're thinking about buying an older Coral Gables house to tear down or rebuild, that letter is the document to look up before you make an offer.

The demolition approval is a letter, and it expires

Coral Gables doesn't treat demolition of a non-designated house as automatic. Ordinance 2023-03 requires the Historic Preservation Officer to approve every demolition permit for a non-designated building. That approval is recorded in a Historical Significance Determination Letter. The letter is not a demolition permit, which the Development Services Department still has to issue, and three things about that letter matter to a buyer:

• It expires. Approval lasts 18 months from issuance. After that it is void unless a demolition permit has already been issued.
• It is public. The ordinance requires letters to be posted online.
• Anyone can appeal it. The code allows it in so many words:

"Any citizen may appeal the approval within 10 days of online posting."

A "not eligible" letter reads plainly. The letter for 707 Anastasia Avenue is dated October 15, 2026, and signed by Historic Preservation Officer Anna C. Pernas. It says the property does not meet the minimum criteria for local landmark designation, so staff will not send a demolition permit application to the Historic Preservation Board. The letter also says it "does not constitute a development order," that it is valid for 18 months, and that once that period ends, "you will be required to file a new application."

When a listing describes an older Gables house as a rebuild opportunity, the real question is whether a letter like this exists for that address, and how much of its 18 months remain.

Why so many letters on the city's list are reissues

The city keeps a public archive called Historical Significance Determination Letters, organized by address. Each entry links to the letter and to the complete file. By the batch posted October 19, 2026, the 2026 section listed about 75 entries.

Each filename ends in a label like L1, L2, L3 or L8. Every letter in the recent batches with a label above L1 describes itself as a reissue.

The 23 Sidonia entry shows the pattern most clearly. Its earlier letter was dated May 6, 2025, so its 18 months would have run out in early November 2026. The October 15 reissue replaced it shortly before then. The same October batch also included 27, 31 and 35 Sidonia Avenue, each labeled L8.

Renewal is cheap compared with starting over. The city's historic preservation fee schedule lists $761.25 for a new determination and $100 to reissue an expired letter. For a lot being held for a rebuild, keeping the letter current costs little compared with what a lapse could mean. Reissues appear in the online archive alongside new letters, and the ordinance ties the 10-day appeal window to online posting.

For a buyer, a house with a current letter and a house with no letter are different purchases, even if the two lots look the same. The first already has a recorded answer. The second still has to go through the process.

What happens when the answer is "eligible"

The process doesn't always end in a "not eligible" letter. The July 23, 2026 letter for 314 Cadima Avenue found that the house met the minimum criteria for landmark designation. It cited one historical and cultural criterion and two architectural criteria. The same letter scheduled the board hearing for September 17, 2026, at 4:00 p.m. at Police & Fire Headquarters, 2151 Salzedo Street. The letter also noted that the final report "may include additional criteria or exclude others after further research is completed."

At the hearing, the board received a letter of support from the Historic Preservation Association of Coral Gables. City staff said the owner's plans would go next to the Board of Architects and then come back to the preservation board for a Certificate of Appropriateness. The city's Legistar record lists the item as passed on 9/17/2026.

It was not the only designation this year. Citizen Portal reported that in August the board unanimously designated 1307 Lisbon Street, a 1925 Mediterranean Revival cottage, citing its architectural integrity and its role in the city's early development.

For the owner of 314 Cadima, who planned to add to the house, designation changed which reviews his plans go through. For a buyer who paid a rebuild price for a lot like that, designation would change what the purchase actually was.

How the clock runs

The ordinance sets the timeline, so a buyer can estimate how long each stage might take:

1. Request. The owner files a request. The city's Historic Preservation page links the form and offers staff meetings about determination letters on Mondays and Wednesdays, 9 a.m. to noon, by appointment. The form asks for a current survey, a letter of intent, color photographs, the application and the fee.
2. Preliminary determination. The Historic Preservation Officer issues it within 45 days of the submittal.
3. If "not eligible." The letter is posted online, and any citizen has 10 days from posting to appeal. An appellant must then submit a completed designation report within 21 days of filing the notice of intent to appeal. The demolition approval lasts 18 months.
4. If "eligible." The final designation hearing before the Historic Preservation Board must take place as soon as practicable and no later than 90 days after the eligibility finding. The hearing can be deferred if the owner and the Historic Preservation Officer agree. The city can also require an independent consultant's analysis, paid for by the applicant.

The 314 Cadima case ran from the July 23 letter to the September 17 vote, which is well within that 90-day limit.

What to pull before you write the offer

The letters are public, so you can check most of this before signing anything. Some practical questions to cover with your agent and attorney:

• Does the address appear on the city's letter archive? If it does, what is the letter date, and when do its 18 months run out?
• Is the letter an original or a reissue, and do the reissues continue without a gap?
• Did the original posting draw an appeal within its 10-day window? The complete file linked beside each entry is where to look.
• If no letter exists, how does your contract timeline compare with the 45-day determination period and, if the finding is "eligible," a hearing up to 90 days later?

This is general information about how the city's process works, not legal advice. Before you rely on a letter's timing or terms for your own purchase, confirm them with a real estate attorney and with the city's Historical Resources office.

Quick answers

Does a "not eligible" letter guarantee I can demolish? The letter itself says it is not a development order. The approval can be appealed within 10 days of posting, and it expires after 18 months unless a demolition permit has been issued.

What does a reissue cost? The city's fee schedule lists $100 to reissue an expired letter and $761.25 for a new determination.

Where can I ask questions about a specific address? The Historical Resources and Cultural Arts office is at 2327 Salzedo Street. You can reach it at 305-460-5093 or [email protected].
