You can see the opportunity. South Florida rents keep climbing, demand never really cools off, and good land is getting harder to find by the year. Maybe you already own a parcel, or a tired single-family house sitting on a lot that could do a lot more. The problem isn’t spotting the upside. It’s getting from a piece of dirt to income-producing units without losing months to zoning fights, permit delays, and code surprises that quietly eat your returns.
That’s where multi-unit / investment projects earn their keep. Instead of one house on one lot, you put the same parcel to work generating two, three, or more rent checks, spreading your land and site costs across multiple income streams. Florida has tilted the field toward this kind of building, too: the state’s Live Local Act now requires cities to fast-track qualifying multifamily projects on commercial and mixed-use land, which is a real edge in a market like Broward where developable parcels are scarce. The construction itself still has to clear hurricane and flood code, so who builds it matters as much as where.
Harris Contracting has handled remodels, renovations, and new residential construction across South Florida since 2019. We’re a State Certified General Contractor, licensed and insured, and a Minority Owned Business serving Fort Lauderdale and the surrounding area. Here’s how an investment build actually comes together here, what the rules require, and where investors get tripped up.
Who Builds Multi-Unit Projects Here
The investors we work with aren’t all institutional developers. Plenty are everyday owners: someone building a duplex to live in one side and rent the other, a landlord adding a triplex on an infill lot, a family converting a property into a small rental building. The common thread is wanting the land to pay for itself, and then some.
What Counts as an Investment Project
It’s a wider category than people assume. A duplex or triplex, a small walk-up apartment building, a build-to-rent project, a rentable accessory unit, or a small mixed-use building with apartments over a storefront all fit. The right one for you depends on your lot, your zoning, and how much capital and patience you’re bringing to it.
Key Takeaways
- Multi-unit / investment projects turn one parcel into several income streams, spreading land and site costs across multiple rentals.
- Florida’s Live Local Act can fast-track qualifying multifamily on commercial and mixed-use land, a real advantage in land-scarce Broward.
- Investment builds still have to meet South Florida’s hurricane and flood code, so the builder you choose drives both your timeline and your returns.
How a Multi-Unit Investment Project Comes Together: Four Steps
An income property is as much a financial project as a construction one. The order below keeps the money side and the building side moving together.
Feasibility and a real pro forma. Before any design, you confirm what your zoning allows, how many units the lot can carry, and whether the rents will service the build. A contractor who knows the local market gives you a construction number you can plug into your returns. Tip: Run your numbers on the conservative side and build in a 10% to 15% contingency. Site work, impact fees, and hurricane-code requirements are where optimistic budgets fall apart.
Design, zoning, and entitlement. Plans get drawn to fit both your investment goals and the local land development code. If you’re pursuing a Live Local or density path, this is where that approval track gets set up. Tip: Roughly 15% of a multi-unit building’s floor area is non-rentable, like stairwells, corridors, and mechanical space. Plan your unit count and rent projections around usable square footage, not gross.
Permits and plan review. Multi-unit work goes through full plan review with your city or Broward County for structural, electrical, plumbing, and mechanical compliance under the Florida Building Code. Tip: On commercial or investment property, Florida law generally requires the owner to hire a licensed contractor rather than self-permit. Lining up a State Certified General Contractor early keeps the permit process clean.
Construction and certificate of occupancy. The building goes up to hurricane-zone standards, gets inspected at every stage, and earns its certificate of occupancy, the document that lets you legally lease the units. Tip: Phase your leasing around realistic inspection timelines. Marketing units before you have a clear path to your CO invites broken move-in promises.
What the Rules Require in South Florida
Investment projects answer to more than the building code. Zoning, density, and state housing law all shape what you can build and how fast you can build it.
Zoning, the Live Local Act, and HVHZ Construction
Your starting point is zoning: the parcel’s land use sets your allowed density, height, and unit count. The Live Local Act can change that math. Passed in 2023 and strengthened by amendments through 2025, it requires local governments to administratively approve multifamily and mixed-use residential on land zoned commercial, industrial, or mixed-use, as long as at least 40% of the units stay affordable to households at or below 120% of area median income for 30 years. In exchange, qualifying projects skip rezonings and public hearings, can build to higher density and height than the base zoning allows, and may claim property tax exemptions on the affordable units. Broward has leaned into this with its own density tools along transit corridors and a county affordable-housing plan, which makes the region one of the more active places to use the law. On the construction side, Fort Lauderdale and the rest of Broward sit in the High Velocity Hurricane Zone, so every unit needs impact-rated openings and wind-load engineering, and parcels in flood zones carry elevation requirements on top of that.
Warning The Live Local Act is powerful, but it’s also new, technical, and actively contested. Cities have pushed back and some provisions have landed in court, so whether your specific parcel qualifies, and on what terms, is not something to assume from a blog post. Build a project around a density or approval path that turns out not to apply and you can lose months and serious money. Confirm eligibility with a licensed contractor and a land-use professional before you commit capital, and pull every permit properly. On investment property, cutting corners on licensing or approvals doesn’t just risk fines; it can stall your financing and your leasing.
Choosing the Right Investment Project for Your Lot
The best project is the one your parcel and your zoning actually support, not the one that looks best on a spreadsheet in isolation. Here are the directions most South Florida investors take, with deeper guides on each.
Matching the Build to Your Goals
- Two or three units on a single lot, often owner-occupied on one side
- A small walk-up apartment building for multiple rentals
- A set of rental homes built to lease rather than sell
- Apartments over ground-floor retail under a mixed-use or Live Local path
- A rentable accessory unit as a lower-cost entry into rental income
Key Takeaways
- A duplex or triplex is the most common entry point, with land and site costs split across multiple rents.
- A rentable accessory unit is the lowest-capital way to start earning rental income on a lot you already own.
- Mixed-use and Live Local projects offer the most upside and the most complexity, so they reward careful entitlement work.

Frequently Asked Questions
How much do multi-unit / investment projects cost to build in South Florida?
Infill multi-unit construction, duplexes, triplexes, and small walk-ups, commonly runs somewhere around $150 to $250 per square foot in our market, with coastal labor and hurricane code pushing toward the higher end. A duplex often lands in the high six figures and a triplex into seven, before land. Those are planning ranges, not quotes; the real number comes from your lot, your unit count, and your finishes, which we’ll price out for you.
What is the Live Local Act, and does it help my project?
It’s a Florida law that requires cities to approve qualifying affordable multifamily on commercially or industrially zoned land without the usual rezoning and hearings, with higher allowed density and possible tax exemptions in return for keeping 40% of units affordable for 30 years. It can be a major advantage, but eligibility is parcel-specific and the law is still being tested in court, so we confirm it with you and a land-use professional before building a project around it.
Do I need a licensed contractor for an investment build?
Yes. For commercial and investment property, Florida generally requires a licensed contractor to pull permits and do the work, rather than an owner-builder. Beyond the legal requirement, lenders and insurers expect licensed, inspected construction, so it protects your financing as much as your building.
