Planning board denies proposed loosening of building‑site separation rules and voluntary demolition pathway

On March 12, 2025 the Coral Gables Planning and Zoning Board voted unanimously (7‑0) to recommend denial of a proposed zoning text amendment that would have changed the conditional‑use standards for building‑site determinations and allowed voluntary demolition of nonconforming structures on lots larger than 20,000 square feet to permit separation into smaller building sites.

Staff presented the proposal as a limited set of changes focused on two issues: clarifying how building‑site frontage consistency is evaluated in conditional‑use reviews, and adding language to allow voluntary demolition of structures that currently straddle lot lines on building sites larger than 20,000 square feet so the site could be split. Staff also proposed restoring a former code provision limiting the total residence square footage allowed on separated sites to the square footage that could have been built if the property were developed as a single building site.

Planning staff said an internal GIS analysis showed approximately 241 single‑family/duplex parcels could potentially be affected if the amendment were adopted, after filtering the city’s 13,518 parcels for size and other constraints.

Supporters of the change, including the sponsoring commissioner, framed the measure as a way to let homeowners update backyards and terraces and to relieve cases where existing detached terraces or garages are unusable in heavy rain. The sponsor described an example of a resident with a 5,000‑square‑foot lot who could not attach a terrace to the house without losing accessory credit and asked staff to seek a forward‑looking solution for future residents.

Opponents, including several board members, said the proposed changes could encourage speculative lot splits, undo long‑standing covenants and unity‑of‑title protections, and alter neighborhood character. Board members also noted the code already contains detailed, parcel‑by‑parcel standards (setbacks, frontage, historic considerations), and opposed removing protections that prevent the creation of nonconformities. Several members said they preferred retaining stronger protections such as unity of title or restrictive covenants and making any change more narrowly targeted.

Staff emphasized that any application under the proposed language would still require a conditional‑use public hearing and review by the Development Review Committee, Board of Architects, Planning and Zoning Board and City Commission; it would not be an administrative bypass. Nevertheless the board voted unanimously to recommend denial.

Key numbers and findings: staff reported 13,518 parcels in the city, 1,747 parcels at or above 20,000 square feet and, after additional filters, about 241 properties in single‑family or duplex zones that could be eligible for review under the proposed text amendment. The proposal would have required that new separated building sites have street frontages “equal to or larger than the majority of existing frontages on the abutting streets” and would have limited the allowable residence square footage on each separated site so the total did not exceed what could be built on the original single site.

Next steps: The board recommended denial and the matter will be reported to the City Commission with the board’s recommendation.
