Permitting A New Build Or Renovation

By Trevor Ducote
Published November 25, 2020

Building codes have existed since ancient times and they have one main goal: to protect the wellbeing of the public.  In Louisiana, each parish has their own set of rules and requirements. That is why it’s best to consult with your parish’s permitting department before building.
To help you out, here is some important information about permitting new builds and renovations in Lafayette:

Residential Building Permits

The Lafayette Parish reviews and approves building plans for renovation, land development, demolition, repairs, and new builds. Their main goal is to assess whether a building is safe to occupy and whether it’s compliant to local regulations. A residential building permit is required for almost all structures associated with a home. This includes single family dwellings, a duplex, carports, gazebos, RV covers, and fences over 7 feet.

Do I Need A Permit?

In Lafayette, all new builds require a permit. That’s not the case for remodels. There are many types of home renovation, from basement upgrades to roof replacement. Some will need a permit while others will not. In Lafayette Parish, you will need a building permit for any type of addition, alteration, repair, or conversion to the main or accessory structure. This includes electrical systems, changing the size of a window opening, mobile home setups, swimming pools, etc. However, some projects typically don’t require permits such as:

  • Cosmetic upgrades  
  • Playhouses and sheds that are detached from the house, smaller than 200 square feet, and on a movable foundation (piers or skids) 
  • Construction/remodel project that cost less than $5000 while not affecting an exit

In the Permitting Department, there is a thin line between renovation and new construction. For example, if you plan to build an addition that will be connected with a breeze-way to your home, you will need to obtain a permit for a new build.

The Permitting Process

If you need to obtain a building permit, the first step is submitting the required documents to the Permitting Department. Typically, homeowners get an answer within 10 days after submitting. The most important documents are:

  • Architect or engineered stamped building plans (for new construction) 
  • Residential Building Permit Application 
  • Written cost estimate of labor and materials (the estimate must be done by a professional) 
  • Copy of contractor’s license and insurance (for projects over $10,000) 
  • An affidavit exempting of contractor’s license (if the homeowners plan to do the project on their own) 
  • Document of ownership (Cash deed, Bill of Sale, Act of Donation, Plat of property) 
  • Elevation Certificate (if you plan to build in a flood zone) 
  • Verification of physical address where the construction will take place

When your new build gets approved, you will need to post the yellow hard card on the electrical pole for temporary electrical services. You will also need to send a copy of the permit to the Health Unit to obtain a sewage permit.

The Building Plan

The most important document when applying for a building permit is the building plan. As mentioned, the plan needs to be stamped by a certified architect or engineer. It should include the site plan as well as plans for the foundation, floor, wall sections, roof framing, basic electrical, plumbing, window, and door schedule, etc. (Not all parishes require stamped plans for renovations or residential construction. Check with your local code office for exact requirements.) Where your property is located, determines the requirements for the property’s dimension. When it comes to residential single-family homes in Lafayette, the standard setbacks are 20 feet from the front or street/corner block, 5 feet from the sides or adjoining property lines, and 10 feet from the back property line. That’s why the site plan can determine whether you will obtain a permit or not. It must be drawn to scale and it should include:

  • The dimensions of all structures (those planned and already built). 
  • The structure’s relationship to property lines, streets, and easements. 
  • Subdivision name, phase, lot, and street address.

You can hand-deliver all these documents to the Permitting Department or you can send them by mail in a PDF format. You can find out more about your area’s setbacks here.

Building In A Flood Zone

If you want to apply for a building permit in a flood zone, you will have to submit an elevation certificate. The certificate shows how your house’s elevation compares to the base flood elevation on a flood map. This determines your property’s floor risk as well as the sum you’ll need to pay for a flood insurance policy. So why does the Lafayette Parish need an elevation certificate for approving new builds and remodels?  Construction projects, especially an add-on can change the house’s lowest point of elevation, influencing its flood risk. When the Permitting Department reviews your application, they will also take this into consideration. You can check whether your property is located in a flood zone on FEMA’s flood maps. For comparison, not all projects in flood zones need an elevation certificate. In Vermilion, you are required an elevation only if you plan to build an addition which costs less than 50% of your home’s current value.
