How a Build Runs
Your Custom Home Build, Phase by Phase
-
Pre-Construction and Approvals
Plans and budget developed together, a soil test where required, your flood zone and base flood elevation, then permits and any historic district review.
-
Site Prep and Foundation
Clearing, grading and utilities, driven pilings if the soil calls for them, then the elevated slab or pier system.
-
Framing and Enclosure
Framing, roof and dry-in, windows and doors, then plumbing, electrical and HVAC rough-ins before the walls close.
-
Interior Finishes
Drywall, cabinetry, flooring, tile, countertops, trim and paint, then fixtures, lighting and appliances.
-
Inspections and Handoff
Final city inspections, the Certificate of Occupancy, your final elevation certificate and a room-by-room walkthrough.
Most builds run three months to a year from plan submission to handoff, and larger homes can take up to 18 months. Windows and doors are the longest lead item, so we lock in those selections early. See the full phase-by-phase timeline.

Building on New Orleans Lots
What Custom Home Builders in New Orleans Plan For
The soil, the flood zone and the historic district map decide what can go on a New Orleans lot and how long it takes to get there. We check all three while the design is still on paper, not after the drawings are done.
-
Soil and foundations
Much of the city sits on soft, high-moisture soil. Depending on your lot, the foundation may be an engineered slab, a raised pier system or driven pilings, and when the city requires a geotechnical soil test, the report decides which.
-
Flood elevation
New construction has to be built at or above the Base Flood Elevation for your parcel. Building higher costs more up front and can lower long-term flood insurance exposure. Look up your lot on FEMA’s Flood Map Service Center.
-
Historic district review
In a local historic district, the design goes through Historic District Landmarks Commission review before permits are issued, and its review meetings run monthly. In the French Quarter, the Vieux Carré Commission reviews instead.
-
Permits and plan review
New construction goes through full plan review, which the city puts at roughly 30 days before any corrections. Budgeting 8 to 12 weeks for permitting is realistic, and a complete first submission saves the most time.
-
Weather and hurricane season
Sustained rain stops grading and concrete pours, and hurricane season runs June through November, so foundation schedules carry contingency days from the start.

Frequently Asked Questions: Custom Home Builds
Find answers to frequently asked questions that address your concerns, assist with decision-making, and ease any doubts you may have.
What makes Sweeney Build different from other custom home builders in New Orleans?
Sweeney Build stands out because of our deep understanding of New Orleans' architectural styles, zoning regulations, and environmental conditions. We combine this knowledge with years of experience to create homes that are not only beautiful but also perfectly suited to their surroundings. Plus, our transparent communication and commitment to quality craftsmanship ensure a smooth process from start to finish.
How do I start the process of building my custom home?
The first step is to schedule a consultation with us. During this meeting, we'll discuss your vision, budget, and timeline for your custom home. From there, we’ll work with you to design your dream home, ensuring every detail reflects your lifestyle and preferences.
How long does it take to build a custom home in New Orleans?
Most of our custom homes take three months to a year from plan submission to handoff, depending on size, and larger builds can take up to 18 months. Pre-construction and approvals come first, then site prep and foundation, framing and enclosure, interior finishes and final inspections. Historic district review, a surprise soil test requirement and late window and door selections are what most often stretch a schedule. Our full build timeline breaks down every phase.
How much does it cost to build a custom home in New Orleans?
It depends on the plans, the lot and the finishes, which is why every custom home is priced from its own drawings. The biggest cost drivers are size and layout, the foundation your soil calls for (slab, raised piers or driven pilings), how far above base flood elevation you build, and your selections for windows, cabinetry and finishes. Lot access, utilities and historic district requirements can add cost too. After we review your plans and site, you get a detailed estimate before you commit.
Do you provide post-construction support?
Yes, we provide post-construction support to ensure everything in your new home is functioning as it should. If any issues arise after completion, we’ll be here to address them. We believe in building lasting relationships with our clients and are committed to your satisfaction long after the build is finished.
Can I customize every part of my home, or do you have pre-designed plans?
At Sweeney Build, we specialize in fully customized homes. While we can offer suggestions or templates based on your preferences, every home we build is unique and designed specifically for you. From layout and materials to finishes and fixtures, the choices are yours.
Do I need pilings to build in New Orleans?
It depends on your lot. Much of New Orleans sits on soft, high-moisture soil, so many lots can't take a standard slab without soil work, engineered fill, a raised pier system or driven pilings. When the city requires a geotechnical soil test, the report decides which foundation your home gets. A soil test isn't required on every build, but it can be requested with little warning, so we plan for the possibility before the foundation is designed.
Can I build a custom home in a historic district?
Yes. If your lot is in a local historic district, the design goes through Historic District Landmarks Commission review before the city issues permits. In full-control districts, new construction usually needs a Certificate of Appropriateness, and larger projects can go to the Architectural Review Committee first. Both meet monthly, so each round of revisions costs a meeting cycle rather than a week. In the French Quarter, the Vieux Carré Commission handles review. We build that time into your schedule and handle the submissions.
Do you build on my lot?
Yes, we build on the lot you own. Before design is finished, we check its zoning and setbacks, flood zone and base flood elevation, utility access and whether a soil test may be needed, since each one shapes what you can build and what it costs. We don't sell land, but if you're still shopping, we can look at a lot with you before you buy so there are no surprises.
What should I expect during the building process?
Throughout the building process, we maintain clear communication with you. You'll be involved in the design phase, receive regular updates on construction, and be consulted on major decisions. Our team handles all the logistics, ensuring the project runs smoothly, on time, and within budget.
