Home Additions
Home Additions — More Room for You or Life's Additions
Second-story additions, room additions, covered patios, and in-law suites built by a licensed Louisiana general contractor. We manage design, engineering, permitting, and construction from start to finish. Serving Metairie, New Orleans, and Jefferson Parish, with additional work on the Northshore and select projects in the Baton Rouge area.
Why Homeowners Choose to Build Up and Out
A home addition is among the most complex residential construction projects. It requires careful integration with your existing structure—matching rooflines, tying into foundations, and connecting mechanical systems while maintaining the architectural character of your home. In Greater New Orleans, additions also require navigating parish-specific zoning, setback requirements, and flood zone considerations that vary significantly from one neighborhood to the next.
As a licensed general contractor (#889646), Cajun Home Services manages home additions from initial feasibility through final inspection. We coordinate design, engineering, permitting, and construction to deliver an addition that looks and functions as if it were always part of your original home. Whether you're adding a second story to a brick ranch in Metairie, building a covered patio in Kenner, or constructing an in-law suite in New Orleans, our team handles the full scope.
Many homeowners choose to build additions rather than relocate because they love their neighborhood, their lot, or their school district. Expanding in place lets you keep what works while gaining the space you need. We help you evaluate whether your property, foundation, and existing structure can support the addition you envision—and we're upfront about what's feasible before you invest in design.
All work is performed by licensed, insured, and documented crews, with twice-daily photo updates and dedicated project management via JobTread.

Types of Home Additions We Build
Each type of addition involves different structural, engineering, and permitting requirements. We have documented experience with all of these project types across Southeast Louisiana.
Second Story Additions
Adding an entire floor above your existing home. Requires structural engineering, steel beam integration, and careful load distribution to your existing foundation. Our most complex—and most rewarding—addition type.
Room Additions
Ground-level expansions including bedrooms, family rooms, and home offices. Requires new foundation, structural tie-in, and matching your existing roofline and exterior finishes.
Covered Patios & Porches
Outdoor living extensions with brick columns, ceiling fans, and weather-resistant finishes. A practical addition for Louisiana's climate that extends your usable living space year-round.
In-Law Suites & Guest Quarters
Self-contained living spaces with private entrances, kitchenettes, and bathrooms. Increasingly popular for multi-generational families in the New Orleans area.
Garage Conversions & Additions
Converting existing garage space or building new attached garages with living space above. Requires careful attention to zoning setbacks and parking requirements.
Custom Outbuildings
Detached workshops, studios, and storage buildings built on new foundations with proper electrical, plumbing, and climate control as needed.
How We Build Home Additions
Every home addition follows a structured process designed to ensure proper integration with your existing structure and compliance with all applicable codes.
Feasibility & Consultation
We evaluate your property, zoning requirements, and existing structure to determine what is possible and practical.
Design & Engineering
Architectural plans developed to complement your existing home, with structural engineering as required.
Permitting & Preparation
We handle all permit applications, coordinate with building officials, and prepare the site for construction.
Construction & Completion
Professional construction with careful integration to your existing structure, followed by final inspections.
Building Additions in Louisiana's Climate
Home additions in Southeast Louisiana face unique challenges that out-of-state contractors often underestimate. Our local experience means we plan for these factors from day one.
Soil & Foundation Challenges
Louisiana's expansive clay soils require engineered foundations with proper pier depth and spacing. We work with structural engineers who understand local soil reports and design foundations that prevent differential settling between your addition and existing home. When an existing home already shows movement, our licensed foundation repair services stabilize it before the addition footprint is laid out.
Hurricane & Wind Resistance
Additions must meet current wind load requirements, which are significantly higher than when many older homes were built. We integrate hurricane straps, proper sheathing, and can build to FORTIFIED standards for maximum storm resilience and insurance savings.
Flood Zone Considerations
Many properties in Greater New Orleans fall within flood zones that affect what you can build and how. We research FEMA maps and local elevation requirements during feasibility assessment to avoid costly surprises during permitting.
Matching Existing Architecture
From raised Creole cottages in New Orleans to ranch-style homes in Metairie, each architectural style requires different approaches to seamless integration. We match rooflines, siding profiles, window proportions, and trim details so your addition looks original.
Service Areas
We provide home addition services throughout Greater New Orleans and surrounding parishes. Our team is familiar with local zoning regulations, setback requirements, and the permit processes in each jurisdiction.
Also offering new construction, whole-home remodeling, roofing, and structural repairs throughout the region.
