For a fourplex, buyers typically pay a wide range depending on location, finishes, and lot conditions. The main cost drivers are land cost, construction type, unit amenities, and permit requirements. This guide focuses on cost and price to help buyers estimate budgets and compare quotes.

Overview Of Costs
The total price for a new 4-plex typically ranges from about $600,000 to $2,200,000+, with per-square-foot costs usually between $120 and $260 depending on finish level and local market conditions. For a 4,000 sq ft total footprint, expect roughly $480,000 to $1,040,000 in construction alone, plus land and soft costs. Realistic budgets often fall in the $1.0M to $1.8M range for mid-range builds in many U.S. markets.
Cost Breakdown
Construction project costs break down across several categories that influence total price. A typical table shows the relative share of materials, labor, permits, and field overhead. The following table uses four to six columns to illustrate totals and per-unit figures, with assumptions noted.

|---|---|---|---|---|
| Materials | $180,000 | $420,000 | $900,000 | Framing, exterior, interiors, fixtures |
| Labor | $180,000 | $420,000 | $840,000 | Carpentry, plumbing, electrical, HVAC |
| Equipment | $20,000 | $60,000 | $120,000 | Rentals, cranes, tools |
| Permits | $8,000 | $20,000 | $60,000 | Municipal fees |
| Delivery/Disposal | $6,000 | $18,000 | $40,000 | Material hauling |
| Warranty | $3,000 | $8,000 | $15,000 | Builder warranties |
| Overhead | $10,000 | $25,000 | $50,000 | General contractor margin |
| Contingency | $15,000 | $40,000 | $100,000 | Unforeseen costs |
| Taxes | $5,000 | $20,000 | $50,000 | Construction-related taxes |

What Drives Price
Price variability hinges on site factors, design choices, and market conditions. Key drivers include the lot’s accessibility, foundation type, and the level of unit amenities. Regional differences in labor costs, material availability, and permit complexity also shift total estimates. For a given design, higher efficiency systems or better insulation can raise upfront costs but reduce operating expenses over time.
Ways To Save
Smart budgeting can trim upfront costs without sacrificing value. Consider standardizing floor plans, selecting mid-range finishes, and batching permits. Scheduling work in off-peak seasons and negotiating long-term supply contracts also helps. The goal is to secure predictable, quality outcomes within a defined budget.
Regional Price Differences
Prices vary by region; three typical patterns show notable deltas. In coastal cities, higher land and labor costs can push total price 10–25% above national averages. Suburban markets often align with national midpoints, while Rural areas may be 5–15% lower due to lower land costs and simpler permitting. Regional differences should be examined alongside site-specific factors to refine budgets.
Labor, Hours & Rates
Labor contributes a large portion of the build cost and varies by crew size and duration. A 4-plex project commonly requires a general contractor, carpenters, electricians, plumbers, and HVAC technicians. Typical crews run 6–14 months, with labor rates ranging from $40 to $120 per hour depending on trade and region. Longer schedules increase carrying costs and financing charges.
Additional & Hidden Costs
Hidden charges can affect final numbers even after bids. Expect costs for utility connections, site drainage, erosion control, landscaping, testing, and potential impact fees. If the site needs grading or environmental mitigation, add a contingency to cover these surprises. Some markets also add impact or school fees beyond standard permit costs.
