Covington · Mandeville · St. Tammany Parish

Duplex and multifamily builder on the Northshore.

Covington, Mandeville and the rest of western St. Tammany, on the lot you choose. The land is there. The hard part is knowing which lots will actually let you build two doors.

Who rents what we build

Close to 95% of the units we manage rent to working families using a Housing Choice Voucher — what most people still call Section 8. That is a choice we made. The housing authority pays its share directly, the tenant share is set at a level the household can carry, and a new, well-built unit is exactly what those families are looking for.

A new unit of ours typically leases in about one month to a month and a half from the day it is ready. Voucher programs are run by a different housing authority in each parish, so the paperwork and the timing change with where you build — we walk you through the one that applies to your lot.

Zoning decides this, not the price of the lot

Most of the Northshore is zoned single-family. A wide, cheap, beautiful lot means nothing if the zoning on it does not permit a two-family dwelling. This is the single most common way a Northshore duplex plan dies, and it dies after someone has already bought the land.

We check zoning, minimum lot size, setbacks and permitted use before you commit to a lot — not after. If a lot will not carry two doors, we say so and we go find one that will.

Three different permit offices

Where the lot sits decides who reviews your project:

  • Inside Covington city limits — City of Covington, with additional review in and around the historic downtown
  • Inside Mandeville city limits — City of Mandeville, which holds real standards on trees, landscape and elevations
  • Unincorporated St. Tammany — St. Tammany Parish Permits and Inspections, with parish drainage review

We handle all three. You do not need to learn the difference — but the lot you choose does change the timeline, and we tell you that up front.

Higher ground, still lot by lot

Much of St. Tammany sits well above the elevations south of the lake, and that can help on both elevation requirements and insurance. It is not a blanket. Parts of Mandeville sit close to the lakefront, and drainage and soil vary street to street. We pull the flood determination on your specific lot before you commit. Anyone who tells you the Northshore does not flood is selling something.

What we build

Two-level duplexes, 2,496 square feet of living area, 3 bed / 2 bath per side — six bedrooms and four bathrooms under one roof, on one loan. Six elevations. Turn-key, including plans, permits, survey and the builder package.

Do not have a lot? We find and secure buildable lots — zoned correctly for two doors. And with your down payment and pre-approval, the lot may be financed into your loan, subject to lender approval.

How people pay for it

  • FHA — 3.5% down. The 2026 FHA limit for a two-unit property in Louisiana is $693,050 — the same figure statewide.
  • VA — $0 down. No monthly mortgage insurance, and eligible veterans can build rather than shop a picked-over resale market.
  • House hacking. Live in one side, rent the other, and see what actually comes out of your pocket.

Investment Property Builders is a home builder — not a lender, a mortgage broker, or a financial advisor. Prices, loan limits, insurance outcomes and flood determinations vary by lot, by program and over time, and nothing here is a quote or a guarantee. Rental demand described here is general market context, not a projection of your results, and rental income is not guaranteed. Zoning, permitting, elevation and drainage requirements are set by the City of Covington, the City of Mandeville, St. Tammany Parish and other authorities, not by us, and they change.

Where We Build

We build wherever you want to build — if the lot is zoned for it.

That is the whole answer. We are not limited to one neighborhood or one parish. We build new-construction duplexes across Greater New Orleans, on the lot you choose. The one thing that decides whether a duplex can go up is the zoning on that particular lot.

The only real limit is the zoning

Not every lot allows two units. Some zoning districts permit a duplex outright, some require going through an approval process first, and some allow one house and nothing more. Two lots on the same street can fall under different districts. The lot decides — not the block, not the neighborhood.

We check it before you buy

Send us the address or the lot number and we pull the zoning, the setbacks, and the height limit, and tell you straight whether two units fit. If they do not, we say so. That check costs you nothing and takes about a day.

If the lot does not work, we find one that does

We source buildable lots across the metro — Orleans, Jefferson and St. Tammany. You are not stuck with a lot that will not take a duplex.

Send us a lot to check

Zoning is set by each parish and can change. Nothing here replaces a zoning verification or a licensed surveyor.
