Orlando, FL Historic Preservation (HP) Overlay District Requirements

The City of Orlando Historic Preservation (HP) Overlay District mandates that all designated landmarks and structures within its boundaries obtain a Certificate of Appropriateness prior to any exterior maintenance, alteration, addition, or demolition. Property owners must adhere to strict architectural standards concerning materials and design, such as a 35-foot height limit for wireless facilities and a prohibition on tandem single-family developments. New construction and additions are required to maintain the historic character of the surrounding area, with specific restrictions on roof visibility and the use of modern siding materials.

Establishment and Purpose of the HP Overlay District

The HP Overlay District is established by the City of Orlando to promote the educational, cultural, and economic welfare of the community by preserving historic structures, monuments, and neighborhoods [Section 58.401]. These areas serve as visible reminders of the history and cultural heritage of the municipality, state, and nation. The regulations are intended to ensure that any work performed on these properties is consistent with the historic character of the structure or the district [Section 62.700].

Designation Process

A property or area in the City of Orlando may be designated as an HP Overlay District through a process that typically includes:

• Citizen Initiative: A petition signed by at least 15% of the property owners in the proposed district [Section 58.402].
• Comprehensive Survey: A survey to record the architectural and historic significance of structures (generally those at least 50 years old) [Section 58.402].
• Review: Successive reviews by the Historic Preservation Board, the Municipal Planning Board, and final approval by the Orlando City Council [Section 58.402].

Certificate of Appropriateness (COA)

In the City of Orlando, no exterior portion of a building, structure, or above-ground utility may be erected, altered, restored, moved, or demolished within an HP Overlay District without an approved Certificate of Appropriateness [Section 62.200].

Exemptions:

• Buildings or structures owned by churches or religious institutions that are exempt from property taxes are not required to obtain a COA for exterior features [Section 62.200].
• Minor repairs using the same materials and size configuration do not require a formal board review [Section 62.704].

Architectural and Design Standards

The City of Orlando applies the U.S. Secretary of the Interior’s "Standards for Rehabilitation" when evaluating COA applications [Section 62.201]. The core requirement is that new work must be compatible with the existing environment in terms of scale, texture, and site plan.

Specific Exterior Requirements

• Wood Siding: Deteriorated wood must be replaced with wood matching the original in size, shape, and texture. The use of aluminum, vinyl, or other man-made siding to cover or replace original wood siding is prohibited [Section 62.704].
• Masonry: Sandblasting is prohibited. Repointing must duplicate original mortar joints in size, composition, and color [Section 62.704].
• Roofs: The original roof shape must be retained. Architectural features like dormers, cornices, and towers must be preserved. Skylights must be flush with the roof and cannot be visible from a public right-of-way [Section 62.704].
• Windows and Doors: Original windows and frames must be retained. If unrepairable, replacements on principal facades must match the original's material, size, and proportions. Tinted or mirrored glass is prohibited on residential facades [Section 62.704].
• Porches: New porches must be compatible with the building's style. Screening on porches must be transparent to ensure the details of the front wall remain visible [Section 62.704].

Standards for Additions and New Construction

Additions to existing structures in the City of Orlando HP Overlay District must match the existing siding in size, shape, color, and texture [Section 62.705].

• Massing: Any new structure exceeding 50 linear feet of street frontage must minimize the facade's mass by adding projections and recesses [Section 62.706].
• Orientation: The front door must be articulated on the principal facade with covered porches, porticos, or stoops [Section 62.706].
• Materials: New construction must use materials and textures similar to contributing structures in the district [Section 62.706].

Demolition and Economic Hardship

Demolition of structures in an HP Overlay District is highly restricted. The Historic Preservation Board evaluates requests based on the structure's significance, the feasibility of reproduction, and the impact on the overall district ensemble [Section 62.707].

Economic Hardship Claims

If a demolition permit is sought due to economic hardship, the applicant must prove they cannot realize a reasonable economic return from the property. However, property owners are not required to prove economic hardship if the structure is [Section 62.708]:

1. Residential and non-income producing.
2. An accessory structure.
3. A partial demolition where the principal facades remain intact.

Signage and Infrastructure Restrictions

Signage within the HP Overlay District is strictly controlled to maintain aesthetic integrity:

• Review: All signs visible from a public right-of-way require review by the Historic Preservation Board or administrative staff [Section 64.101].
• Transit Infrastructure: Advertising signs are strictly prohibited on transit shelters within any historic preservation district [Section 64.276].
• Digital Billboards: Off-premises digital billboard signs are prohibited within an historic district or within 400 feet of an historic district boundary [Section 58.1220].
• Landmark Signs: The City of Orlando may designate specific "Landmark Signs" that exemplified the city's commercial history (e.g., mid-1900s automobile-era signs), exempting them from some standard sign height or size restrictions [Section 64.264, 64.266].
