Summary

Martin County's Historic Preservation Board approves historical markers and issues certificates of designation under LDR § 4.582.A.3. A designated site or district can carry a plaque prepared by the board with the owner, but under § 4.585.E the plaque, or its removal, changes nothing about the designation or the Division 13 rules that bind the property.

These county ordinances apply to unincorporated areas of Martin County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

4.582.A. Powers and duties. There is hereby created an historic preservation board (HPB). The powers and duties of the HPB include, but are not limited to the following: 1. Recognize archaeological geo-environmental zones as identified on an archaeological survey of Martin County. 2. Designate historic sites and districts pursuant to section 4.584 . 3. Approve historical markers and issue certificates of designation. ... 4.585.E. Designated historic sites and districts may be recognized by placement of an appropriate plaque, prepared by the HPB in coordination with the property owner recognizing the designation and placement on the local register of historic places. The placement or removal of the plaque shall have no effect on the designation of the historic site or district or the application of the provisions of division 13 to the historic site or district.

Full Breakdown

Martin County handles landmark and monument recognition in Division 13 of Article 4 of its Land Development Regulations. The Historic Preservation Board (HPB) has nine members appointed by the Board of County Commissioners, all county residents: four designated seats (an architect, a general contractor, a realtor and a person with Martin County history knowledge) and five at-large seats, each on a four-year term. Five members make a quorum, the board meets at least quarterly, and its agenda goes on the County website at least 24 hours before a meeting. Of the 17 duties in § 4.582.A, item 3 is approving historical markers and issuing certificates of designation. The code defines a historic marker as an official marker whose size, design, wording and location the HPB has approved and which complies with the state historic marker program specifications.

A site qualifies under § 4.583 when it is significant in the history, architecture, archeology or culture of Martin County, ties to significant people or events, embodies a distinctive style or method of construction, has yielded or is likely to yield information about history or prehistory, or is listed in the National Register of Historic Places. Cemeteries, birthplaces, religious properties, moved structures, commemorative properties and anything that gained significance within the last 50 years are screened out unless they fit a listed exception.

The process starts with a petition from the property owner, or from a majority of owners for a district. It must include the recorded deed, an explanation of how the site meets § 4.583, the master site file if one exists, a location map and a site plan. Within 30 days the HPB either directs staff to begin or denies the petition. Staff then has 60 days to deliver an investigation and designation report. A public hearing follows no sooner than 15 days and no later than 60 days after that report, with newspaper notice at least 15 days ahead. The HPB then approves, approves with modifications or denies by resolution, recorded in the public records and shown in the Property Appraiser's records. If the HPB itself proposes designating private property, the owner can accept or reject it.

Under § 4.585.E a designated site or district can receive a plaque prepared by the HPB in coordination with the owner. The plaque is recognition only: putting it up or taking it down has no effect on the designation.

Violations & Fines

Section 4.592 sends enforcement of Division 13 to chapter 1, article 4 of the Code of Laws and Ordinances rather than stating a fine of its own. On a designated site, the Building Department cannot issue a building permit without a certificate of appropriateness, and it issues stop work orders on work that departs from one; no work proceeds while the order stands (§ 4.586.F and G). Skipping or removing a plaque is not a violation, because § 4.585.E gives it no legal effect. Appeals of final HPB actions go to the Board of County Commissioners under section 10.10.E of Article 10 (§ 4.591).

Frequently Asked Questions

Does a plaque on my Martin County property make it a protected landmark?
No. Section 4.585.E treats the plaque as recognition of a designation that already exists. Placing it or removing it has no effect on the designation or on how Division 13 applies to the site. Protection comes from the certificate of designation the Historic Preservation Board issues after a petition, staff report and public hearing.
Who can ask for a historic designation in Martin County?
The property owner, or a person holding the owner's power of attorney, files a petition for a historic site. For a district, a majority of the property owners in the proposed district must file. The HPB can also start the process itself, but an owner of private property approved that way can accept or reject the designation.
How long does the designation process take?
The HPB has 30 days after filing to direct staff to begin or deny the petition. Staff then has 60 days to submit a designation report, and the public hearing falls between 15 and 60 days after the report is filed. Newspaper notice must run at least 15 days before the hearing.
What financial help exists for a designated Martin County property?
Section 4.593 makes designated sites and contributing district properties eligible for county or state preservation funds, and the county can pay relocation fees for a historic resource after HPB review and Commission approval. Section 4.594 lets the Commission exempt up to 100 percent of the assessed value of qualifying improvements from county-levied taxes for up to ten years.
Does Division 13 apply inside Martin County's cities?
Mostly no. Section 4.581.A.2 applies Division 13 to the unincorporated area and to property the county owns or leases inside incorporated areas. The tax exemption in § 4.594 also reaches incorporated areas, but only for ad valorem taxes the Board of County Commissioners levies.
