A remodel on an Old Northeast bungalow, a Granada Terrace two-story, or a Historic Kenwood cottage is not just a Florida Building Code project. It sits under three overlapping regulatory layers, a St. Petersburg city code chapter, a Florida statute, and a federal preservation framework, that a homeowner, an architect, and a contractor all have to satisfy before a hammer swings. Miss the wrong section and the plans review kicks back, the Certificate of Appropriateness (COA) gets denied, or the permit stalls two to four months waiting for a Historic Preservation Commission hearing.

This guide walks the specific code sections that govern historic-district work in St. Petersburg, cited by chapter and section so a property owner or contractor can pull the same regulation and see the same answer. It covers the local City Code Chapter 16.70 rules, the Florida Statute Chapter 267 layer, the federal Secretary of the Interior's Standards that St. Pete's design review is built on, and the Florida Building Code Existing Building Chapter 12 provisions that let historic buildings depart from strict new-construction code where needed to preserve character.

Core answer: A code-compliant renovation in a locally-designated St. Petersburg historic district requires (1) a Certificate of Appropriateness issued under City Code Section 16.70.060 before any building permit is released, (2) design review against the Secretary of the Interior's Standards for Rehabilitation as adopted through City Code Section 16.70.080 and 36 CFR Part 68, (3) compliance with the Florida Historical Resources statute (Chapter 267) where state review is triggered, (4) if the property is on the National Register or a contributing property in a locally-designated district, awareness of National Historic Preservation Act Section 106 review when federal funds or permits touch the project, and (5) Florida Building Code Existing Building Chapter 12 accommodations that allow the building official to accept alternative compliance where strict new-construction code would destroy historic character. St. Petersburg operates two overlapping registries: the National Register (federal, primarily honorific) and the St. Petersburg Register of Historic Places (local, with active COA design review). Local-designation districts and blocks, including Granada Terrace, Mirror Lake, and multiple street-block designations in the Old Northeast (200 Block of 10th Avenue NE, 700 Block of 18th Avenue NE, Welch's Mediterranean Row), plus individually-designated landmarks are subject to the full Chapter 16.70 review layer. National Register districts like North Shore (the historic core of Old Northeast), Historic Kenwood, Roser Park, and Round Lake (Historic Uptown) carry federal designation but do not by themselves trigger local COA review unless a property is also locally designated. Verify your property's specific designation at the St. Petersburg Historic Preservation office before assuming which layer applies.

The three regulatory layers that govern historic work in St. Pete {#three-layers}

Three separate governments have a say in what happens to a historic property in St. Petersburg, and each speaks through its own code volume:

Local, City of St. Petersburg City Code Chapter 16.70 (Historic and Cultural Resources). This is the operative layer for most homeowners. Chapter 16.70 creates the Historic Preservation Commission (HPC), defines locally-designated landmarks and districts, and requires a Certificate of Appropriateness before any exterior change visible from a public right-of-way. If your home is a contributing property in a locally-designated district, Granada Terrace, Mirror Lake, one of the Old Northeast street-block designations (200 Block 10th Avenue NE, 700 Block 18th Avenue NE, Welch's Mediterranean Row), or an individually-designated local landmark, Chapter 16.70 applies to you. National Register properties without local designation are not subject to Chapter 16.70 COA review. Enforcement is through the city building permit process, no COA, no permit.

State, Florida Statute Chapter 267 (Historical Resources). Chapter 267 creates the Division of Historical Resources within the Florida Department of State and designates the State Historic Preservation Officer (SHPO) at Section 267.081. The statute governs state-level review, ad valorem tax exemptions for historic properties under Section 196.1997, and the state's participation in the federal National Register program. Chapter 267 rarely touches a private homeowner directly unless the project uses state funds or is a state-owned property; more commonly it becomes relevant when a homeowner applies for the property tax exemption under Section 196.1997 or the state-portion of the Federal Historic Rehabilitation Tax Credit under IRC Section 47.

Federal, National Historic Preservation Act (NHPA) and 36 CFR Parts 60, 61, 67, and 68. The NHPA (54 U.S.C. Section 306108, the codified Section 106 language) requires federal agencies to consider effects on historic properties before issuing permits, licenses, or funding. For most private residential remodels, Section 106 does not trigger, the project is private, not federal. But the federal layer becomes operative when a property is on the National Register of Historic Places (36 CFR Part 60), when the owner claims the 20-percent Federal Historic Rehabilitation Tax Credit under IRC Section 47 and 36 CFR Part 67, or when a Certified Local Government (CLG) reviews the project under 36 CFR Part 61, which St. Petersburg is.

The practical takeaway: for a typical Old Northeast remodel, the local Chapter 16.70 layer is what you interact with. The state and federal layers show up as (a) the underlying design standards adopted by 16.70.080, (b) tax-incentive eligibility, and (c) any project touching federal funds or federal permits.

City Code Chapter 16.70: the local rule set {#chapter-16-70}

Chapter 16.70 is organized into ten operative sections. The sections most-cited for a residential remodel:

Section 16.70.020, Definitions. Defines "certificate of appropriateness," "contributing property," "historic district," "historic landmark," and "alteration." A common misread: 16.70.020 defines "alteration" broadly to include any exterior-appearance change visible from a public right-of-way, repainting, front-yard fence changes, and mailbox post changes all qualify.
Section 16.70.040, Historic Preservation Commission (HPC). Establishes the seven-member HPC, its powers, and its duties.
Section 16.70.050, Designation of Local Historic Landmarks and Districts. Local designation is separate from and additional to National Register listing.
Section 16.70.060, Certificate of Appropriateness (COA) Required. The trigger section, no exterior work visible from a public right-of-way may proceed on a contributing property in a locally-designated district or on a locally-designated landmark without a COA.
Section 16.70.070, COA Review Procedures. Three review tracks: administrative (staff), consent agenda, and full HPC hearing.
Section 16.70.080, Design Review Standards. Adopts the Secretary of the Interior's Standards for Rehabilitation (36 CFR Part 68).
Section 16.70.090, Demolition and Relocation Review. Requires a demolition COA plus a mandatory delay period (typically 180 days) for HPC to explore alternatives.
Section 16.70.100, Economic Hardship Determination. The pressure-relief valve when full compliance would deprive an owner of reasonable use.

Full Chapter 16.70 text lives at stpete.org/planning/historic_preservation with cross-references to the city zoning code at Chapter 16.30 (Zoning Districts and Overlay Provisions), which layers historic-district overlay zones on the underlying zoning district.

Section 16.70.060 and 16.70.070: when a COA is required and how it is reviewed {#coa-required}

Section 16.70.060, When a COA is required. A COA is required for any exterior alteration, new construction, addition, demolition, or relocation on:

A locally-designated historic landmark;
A contributing property within a locally-designated historic district;
A non-contributing property within a locally-designated historic district when new construction, addition, or demolition is proposed.

Section 16.70.060 applies to changes visible from a public right-of-way. Interior work, kitchens, bathrooms, electrical, plumbing, HVAC, is not reviewed by HPC even in a contributing property. But interior work that changes exterior openings (a new side-elevation window installed as part of a kitchen remodel) becomes an exterior alteration.

Section 16.70.070, Review procedures. Three tracks, each governed by the same design review standards under 16.70.080 but with different procedural intensity:

Administrative review (staff-level, 2 to 3 weeks). Staff of the Historic Preservation office reviews and issues the COA without HPC action. Reserved for minor exterior repairs that match existing conditions in kind and material, replacing a rotted porch board with a matching board, repainting in an approved historic color, in-kind window pane replacement, roof-shingle replacement with matching material.

HPC consent agenda (4 to 6 weeks). Staff reviews first and recommends approval; HPC votes the agenda as a block at the next scheduled meeting. Reserved for larger scopes that still fit design standards clearly, window replacement with appropriate profile and divided-light pattern, roof replacement with documented matching material, side- or rear-elevation additions that do not alter the front facade.

HPC full hearing (6 to 12 weeks, sometimes longer). Any scope that raises design questions, any front-elevation change, any addition visible from the front, and any demolition COA. Requires permit-grade drawings, a design statement from the architect, and public hearing with notification of adjacent property owners.

Section 16.70.060(D) allows the Historic Preservation officer to require a scope shift between tracks, a scope that appears eligible for staff review can be pulled to consent agenda or full hearing if the officer identifies design questions during initial review. This is common when a project team submits at the administrative track but the proposed material, profile, or fenestration pattern is not clearly in-kind.

Section 16.70.080: the design review standards {#design-standards}

Section 16.70.080 is where HPC decides yes or no on a project. The section adopts by reference the Secretary of the Interior's Standards for Rehabilitation (the 10 Standards) codified at 36 CFR Section 68.3(b), plus supplemental St. Petersburg-specific guidelines for each historic district.

The 10 Standards, applied verbatim by 16.70.080, in short form:

Standard 1, Compatible use requiring minimal change to distinctive materials, features, spaces, and spatial relationships.
Standard 2, Retain historic character; avoid removal or alteration of distinctive features.
Standard 3, No false historical development; no conjectural features or elements borrowed from other properties.
Standard 4, Retain changes that have acquired historic significance in their own right.
Standard 5, Preserve distinctive materials, features, finishes, and craftsmanship.
Standard 6, Repair rather than replace deteriorated historic features; where replacement is necessary, match design, color, texture, and, where possible, material.
Standard 7, Gentlest means for chemical or physical treatments; no damaging treatments.
Standard 8, Protect archeological resources in place; mitigate if disturbance is unavoidable.
Standard 9, New work compatible but differentiated; additions and new construction must not destroy historic materials, features, or spatial relationships, and must be distinguishable from old work while sympathetic in size, scale, proportion, and massing.
Standard 10, Reversibility; new additions should be undertaken such that removal in the future would leave the historic property's essential form and integrity unimpaired.

Standard 6 is the single most-cited reason HPC asks for a second submission on Old Northeast window projects. National Park Service Preservation Brief 9 (Repair of Historic Wood Windows) is the reference HPC staff will point to. Standard 9 governs rear and side additions; NPS Preservation Brief 14 (New Exterior Additions to Historic Buildings) is the reference. Neither standard is a blanket ban on modern design, Standard 9 explicitly wants new work distinguishable from historic fabric.

Florida Statute Chapter 267 and the state historic preservation office {#state-layer}

Florida Statute Chapter 267 (Historical Resources) is the state layer. The sections most relevant to a private property owner:

Section 267.031, Division of Historical Resources within the Florida Department of State.
Section 267.061, Duties of the Division. Section 267.061(1)(b) directs the Division to maintain the Florida Master Site File; Section 267.061(3)(a) directs the Division to nominate properties to the National Register through the SHPO.
Section 267.081, State Historic Preservation Officer (SHPO). Designates the Division Director as Florida's SHPO for purposes of the National Historic Preservation Act.
Section 267.1735, Historic Preservation Grants. Governs state grant-in-aid programs.
Section 196.1997, Ad Valorem Tax Exemption for Historic Properties. Authorizes local governments to grant a property tax exemption on the assessed value of improvements for up to 10 years, provided the improvements meet the Secretary of the Interior's Standards. St. Petersburg has adopted this exemption.
Section 196.1998, Historic Property Used for Nonprofit Purposes. Full exemption for qualifying nonprofit-owned properties.

Section 196.1997 is where the state layer becomes actionable for most homeowners. Application is filed with the Pinellas County Property Appraiser after rehabilitation is complete; the Division reviews for compliance with the Standards; if approved, the improvement-value increase is exempted from the ad valorem base for the exemption term.

The Secretary of the Interior's Standards for Rehabilitation {#federal-standards}

The federal-layer regulatory anchor is 36 CFR Part 68, The Secretary of the Interior's Standards for the Treatment of Historic Properties. Part 68 defines four possible treatments:

Preservation (Section 68.3(a)), retention and stabilization of existing form, features, and materials.
Rehabilitation (Section 68.3(b)), repair and alteration for compatible use while preserving historic character.
Restoration (Section 68.3(c)), return to a specific period of significance; removal of non-period features.
Reconstruction (Section 68.3(d)), depiction of a vanished non-surviving property with new construction.

Rehabilitation is the treatment most residential remodels operate under. It permits alteration and modern additions to accommodate current use while requiring compatibility with historic character.

The related federal certification framework is 36 CFR Part 67, Historic Preservation Certifications by the Secretary of the Interior. Part 67 governs the certification process for the 20-percent Federal Historic Rehabilitation Tax Credit under IRC Section 47. The tax credit is not available for owner-occupied primary residences, it applies to income-producing property. But the certification framework at Part 67 sets the review procedure the Division of Historical Resources (as SHPO) and the National Park Service jointly follow to certify a property and a rehabilitation, and it uses the same 10 Standards from Part 68.

For any project pursuing either the state Section 196.1997 exemption or the federal IRC Section 47 credit, the project team is documenting compliance with the same 10 Standards HPC applies at Section 16.70.080 review.

FBC Existing Building Chapter 12: code relief for historic buildings {#fbc-eb-12}

The Florida Building Code Existing Building volume (FBC-EB), 8th Edition, contains Chapter 12, Historic Buildings specifically to let the building official accept alternative compliance on historic buildings where strict new-construction code would harm historic character.

Section 1201.1, Scope. Chapter 12 applies to any building or structure that is listed in the National Register of Historic Places, designated as historic under an applicable state or local law, or certified as a contributing resource within a National Register-listed or locally-designated historic district.
Section 1201.2, Report. Requires a preliminary report identifying the code sections proposed for departure and the rationale for each departure.
Section 1202.1, Judgment of the building official. States: "The provisions of this code relating to the construction, repair, alteration, restoration and movement of structures, and change of occupancy shall not be mandatory for historic buildings where such buildings are judged by the code official to not constitute a distinct life-safety hazard." This is the operative section that permits departure from strict FBC-R compliance for repairs and rehabilitation of contributing properties.
Section 1203, Flood Hazard Areas. Provides limited flood-code accommodations for historic buildings, subject to the underlying federal 44 CFR Section 60.6 variance provisions.

Chapter 12 does not exempt historic buildings from safety compliance. Life-safety, structural, and egress requirements still apply. But it lets the building official accept a repaired original window in place of a code-current impact-rated replacement, or an original wood-lath-and-plaster wall assembly in place of a modern gypsum board assembly, where the departure does not compromise a life-safety objective.

Practical remodel implications: what stops your permit and what doesn't {#practical-implications}

Five issues most commonly stall an Old Northeast, Granada Terrace, or Historic Kenwood permit in plans review or HPC:

Window replacement specs. Standard 6 (repair over replace) drives the top HPC pushback. Original wood double-hung windows should be evaluated for repair first. Where replacement is necessary, matching material, profile, muntin pattern, and divided-light count are required. Vinyl and aluminum replacements are typically rejected on contributing properties.
Front-elevation changes. Any change to a front facade, door, railing, front-yard fence, street-visible window, pulls the project from staff to consent agenda or full hearing.
Additions visible from a public right-of-way. Standard 9 governs. Compatible in size, scale, proportion, and massing but visually differentiated from the original. Full HPC hearing is the default.
Demolition of a contributing property. Section 16.70.090 requires a demolition COA plus a mandatory delay period. Demolition-by-neglect claims are enforced under Section 16.70.090(E).
Non-compatible materials. Modern siding profiles, non-period roofing, and modern railing details are the most common material rejections. In-kind material with original-spec documentation is the safe path.

What does not trigger HPC review, regardless of location in a district: interior renovations that do not change exterior openings; rear-yard work fully screened from public rights-of-way; in-kind repairs at the administrative track under Section 16.70.070(A); and emergency storm-damage stabilization, provided a COA follow-up is filed under Section 16.70.070(D).

Owner-domain note from Revolution: We have run historic-district projects in St. Petersburg since 2017, including work in Old Northeast on projects that involved COA review. We are not a certified historic preservation contractor, no such certification is required to work in a St. Petersburg historic district under Chapter 16.70, and we do not claim credentials we do not hold. What we bring is experience with the COA submission-and-review sequence, relationships with the architects in town who do most Old Northeast permit-grade drawing sets, and carpenters who have repaired wood sash windows and matched period trim profiles on other district projects.

Cost and timeline impact {#cost-impact}

The historic-district code layer adds three cost categories to a St. Petersburg remodel:

COA filing fees. St. Petersburg schedule: $50 administrative, $150 consent agenda, $300 full HPC hearing (verify current schedule at stpete.org/planning/historic_preservation).
Design and documentation cost. Historic-district projects require permit-grade architectural drawings, elevations, existing-condition photographs, and material specifications at higher detail than a typical remodel. A residential architect experienced in Old Northeast COA work typically bills $1,500 to $4,500 above base design fee.
Material and labor premium. Standard 6 and Standard 9 tend to push selections to the higher end of the price band, period-accurate wood windows, matching profiles, custom-milled trim. Skilled labor for wood-sash repair and period trim carpentry is scarce.

Timeline impact: administrative review 2 to 3 weeks; consent agenda 4 to 6 weeks; full hearing 6 to 12 weeks (longer with continuance or second submission). Building permit review runs in parallel or after COA depending on plans-examiner sequencing; total pre-construction timeline for a full-hearing historic project routinely lands at three to five months.

Frequently asked questions {#faq}

Do I need a Certificate of Appropriateness for interior work in Old Northeast? No. Section 16.70.060 applies to exterior alterations visible from a public right-of-way. Interior kitchen, bathroom, electrical, plumbing, and HVAC work does not require COA review even in a contributing property. But interior work that adds or removes exterior openings, a new side-elevation window, a rear door relocation, becomes an exterior alteration subject to COA review.

Does a National Register listing alone require COA review? No. National Register listing under 36 CFR Part 60 is a federal honorific designation and does not by itself impose COA review at the local level. In St. Petersburg, COA review under Chapter 16.70 is triggered by local designation as a contributing property in a locally-designated district or as a locally-designated landmark. Many Old Northeast properties are both National Register and locally designated, but it is the local designation that triggers COA.

Can I replace my original wood windows with vinyl or aluminum in a St. Petersburg historic district? Typically no on a contributing property. Section 16.70.080 adopts Standard 6 of the Secretary of the Interior's Standards, which prefers repair over replacement. Where replacement is documented as necessary, matching material (wood for wood), profile, muntin pattern, and divided-light count are required. Vinyl and aluminum replacements are typically rejected on contributing properties. NPS Preservation Brief 9 documents acceptable repair techniques.

Am I eligible for the Florida ad valorem tax exemption for a historic renovation? Potentially. Florida Statute Section 196.1997 authorizes local governments to grant a property tax exemption on the assessed-value increase from a qualifying historic rehabilitation for up to 10 years. St. Petersburg has adopted this ordinance. Eligibility requires the completed work to meet the Secretary of the Interior's Standards; application is filed with the Pinellas County Property Appraiser after completion.

Does the Federal Historic Rehabilitation Tax Credit apply to my Old Northeast bungalow? Only if the property is income-producing. The 20-percent federal credit under IRC Section 47 and 36 CFR Part 67 applies to certified rehabilitations of certified historic structures that are income-producing (rental, commercial). Owner-occupied primary residences are not eligible.

What is the difference between a contributing and a non-contributing property? Section 16.70.020 defines both. A contributing property adds to district historic significance, typically built during the period of significance and retaining historic integrity. A non-contributing property is within district boundaries but does not add to significance (built outside the period, or so heavily altered that integrity is lost). Contributing properties are subject to the full Chapter 16.70 review layer; non-contributing properties are subject to COA only for new construction, additions, and demolition.

Can FBC Existing Building Chapter 12 give me relief from current code on my historic house? Yes, at the building official's discretion under Section 1202.1. Chapter 12 permits departure from strict FBC-R new-construction requirements where the departure does not create a distinct life-safety hazard. The project team files a preliminary report under Section 1201.2 identifying the sections proposed for departure and the rationale. Life-safety, structural, and egress requirements are not waivable; material and assembly requirements often are, where an original historic assembly can be preserved without a hazard.
