Historic Home Additions in Franklin, TN — Step‑by‑Step Design & COA Guide

Table of Contents

If you’ve ever cracked open the 140‑page Franklin Historic District Design Guidelines and felt your eyes glaze over faster than Tennessee sweet tea on a July afternoon—take heart. This guide is your clear, compass‑steady companion. We’ve translated the city’s fine print into plain‑spoken steps, stitched every rule to its exact page link, and wrapped it all in the Love • Serve • Build spirit that shapes our work at Epic Life Creative.

Think of your historic home as a hymn handed down through generations—its verses sung in brick, clapboard, and time‑worn trim. An addition or new outbuilding should feel like the harmony line: recognizable, respectful, unmistakably fresh, yet never drowning out the original melody. That’s the heartbeat of Franklin’s code, and it’s the through‑line of this manual.

Inside you’ll find:

  • Fast‑Track checklists so you know exactly who to call and when (before costly redesigns or surprise rejections).

  • Green‑light vs. Red‑flag tables turning dense regulations into quick “do this / skip that” snapshots.

  • Full, copy‑and‑paste URL links to every cited page—no hunting, no guesswork.

  • Expandable FAQs for the midnight “Wait, can I use HardiePlank?” questions.

  • Blueprints for accessory buildings (because a studio, garage, or carriage house can sing in harmony, too).
