With home prices in Fort Lauderdale rising over 40% since 2020 (source: Redfin), many Broward County homeowners are turning to Accessory Dwelling Units (ADUs) and home additions to create more space, generate income, or accommodate multigenerational living. At Blue Construction & Plumbing, we specialize in building affordable ADUs and custom home additions that comply with local zoning laws. Here’s everything you need to know before getting started.
1. What Is an ADU or Home Addition?
An ADU (also known as a backyard cottage, garage conversion, or basement apartment) is a secondary living unit built on the same lot as your primary home. A home addition typically involves expanding your current space—like adding a bedroom, bathroom, or larger kitchen.
Benefits of building an ADU or home addition:
💰 Generate rental income ($1,500–$2,500/month in Broward County)
🏡 Create space for family (aging parents, adult children, in-laws)
📈 Boost your home’s resale value (ADUs can increase value by 20–30%)
Pro Tip: Florida’s Live Local Act (2023) makes it easier than ever to build an ADU in Fort Lauderdale—take advantage of the new laws while you can!
2. ADU & Home Addition Costs vs. ROI in Broward County
ADU Construction Costs: $120,000–$250,000 depending on size, materials, and location.
Monthly Rental Income Potential: $1,800–$2,500 (Fort Lauderdale averages) ROI Timeline: Most homeowners break even in 5–7 years.
Example: A $180,000 ADU renting for $2,000/month pays for itself in 7.5 years—after that, it’s all profit.
Home Addition Costs by Size:
Addition Size – Estimated Cost
- 12×12 (144 sq ft) $18,000 – $37,000
- 20×20 (400 sq ft) $51,000 – $102,000
- 20×30 (600 sq ft) $76,000 – $153,000
- 20×40 (800 sq ft) $102,000 – $204,000
- 25×40 (1,000 sq ft) $127,000 – $255,000
