Baton Rouge has some of the most beautiful older neighborhoods in Louisiana. From the oak-lined streets of Beauregard Town to the Craftsman cottages of Drehr Place and the colorful shotgun houses of Spanish Town, owning a home in one of these areas is a point of pride for a lot of residents – and a lot of homeowners want to update their bathrooms and interiors without getting tangled up in the historic review process.
Here’s the good news: if the update is on the inside, in most cases it isn’t reviewed at all.
Baton Rouge’s Historic Districts
Baton Rouge has eight neighborhoods listed on the National Register of Historic Places: Spanish Town, Beauregard Town, Roseland Terrace, Main Street, LSU, Drehr Place, Kleinert Terrace, and Southern University.
There’s an important distinction between a federal historic designation and a local one. Federal designation is primarily honorary and enables property owners to apply for historic preservation tax credits on qualifying work, but it doesn’t restrict what you can do with your property day-to-day. Local designation is where regulatory review comes in – Spanish Town and Drehr Place both have locally designated historic district status with formal design guidelines on file through the East Baton Rouge Parish Planning Commission. Not sure which applies to your home? The Planning Commission can tell you: 225-389-3144, or see brla.gov/2577/Historic-Districts.
What the Certificate of Appropriateness Actually Covers
If your home is in a locally designated historic district, any exterior change visible from a public street requires a Certificate of Appropriateness (COA) before work begins – that covers things like exterior window replacement, siding, and visible additions. Full details are available at brla.gov/2984/Certificate-of-Appropriateness.
What it does not typically cover: interior renovations that aren’t visible from the street. That’s an important distinction for anyone updating a bathroom, closet, or living space inside a historic home.
Interior Glass and Mirror Upgrades You Can Make Without Review
Because they don’t change your home’s exterior appearance, the following upgrades generally fall outside the COA process entirely:
Custom Mirrors
A custom-framed mirror – through partners like Precision Frameworks and Larson Juhl – can be built to match your home’s existing trim, moulding style, and period details. Beveled and antique-finish mirrors also pair especially well with historic interiors.
Shower Enclosures
Updating an old, leaky shower to a frameless or semi-frameless glass enclosure is one of the most common historic-home bathroom upgrades we see – it modernizes the space while respecting everything else about the room’s character.
Decorative Glass
Cabinet glass, glass shelving, and glass backsplashes let you bring some of the era-appropriate detail work back into kitchens and bathrooms without touching the building envelope.
If You Do Need Exterior Glass Work
If your project does involve exterior glazing in a locally designated district, we’re happy to provide documentation on glass specifications to support a COA application, and to make recommendations that respect the character of your home.
