Metairie's Ranch Homes Have Room to Grow.

Metairie’s mid-century housing stock was built on larger lots than most newer suburban development, which means many homeowners have the space to add a room, a garage conversion, or a second-story addition without running into setback issues. The challenge is doing it right — structurally integrating the addition with a slab-on-grade foundation, properly sizing the HVAC to account for the new square footage, and matching the exterior so the addition doesn’t look like an afterthought. We plan and execute additions in Metairie with all of these factors accounted for from the start.

About Home Additions Across Metairie

Metairie’s mid-century ranch homes offer solid addition potential. Single-story slab construction with larger lots means many properties can accommodate room additions, garage conversions, sunroom additions, or rear expansions without major structural complications. Old Metairie’s larger lots and older homes present slightly different considerations but similar opportunities. Jefferson Parish permitting handles all addition work in Metairie, and the process is generally straightforward for compliant additions within setback and lot coverage requirements. We work throughout all of Metairie’s neighborhoods on additions of every scope.

Frequently Asked Questions

Does Quillen Construction Group build home additions in Metairie?

Yes. We serve Metairie homeowners with home addition services throughout Jefferson Parish. We build room additions, master suite additions, sunroom additions, second-story additions, and garage conversions on Metairie’s mid-century ranch homes and other residential construction types throughout the community.

What types of home additions are most common in Metairie?

Metairie’s mid-century ranch homes were built with compact, single-story layouts that frequently feel undersized for how families live today. The most common additions we build in Metairie are rear room additions that expand the living area or add a bedroom, master suite additions that give the primary bedroom a dedicated bathroom and closet space, and sunroom additions that add livable square footage in a bright, open configuration. Second-story additions are also feasible on many Metairie properties where the existing slab and foundation can support the additional load.

Do you handle Jefferson Parish permits for home additions in Metairie?

Yes. We manage all permitting and inspection coordination with Jefferson Parish on every addition we build in Metairie. This includes verifying setback and lot coverage compliance before the scope is finalized, submitting all permit applications, and managing inspections through completion. We don’t hand that process off to the homeowner.

How do I know if my Metairie lot can support an addition?

That’s exactly what we determine during the initial site visit. Jefferson Parish has specific setback and lot coverage requirements that vary by zoning classification, and we check those against your specific parcel before writing any scope. In many cases Metairie’s mid-century lots have more room than homeowners realize. In others, the constraints are real and shape what’s possible. We give you an honest answer upfront rather than discovering limits mid-project.
