Is Building a New Home in Los Angeles Really Take That Long? 

Phase 1: Pre-Construction (6–12 Months)

This is where the real groundwork begins—not with a shovel, but with research, plans, and city paperwork.

1.1 Feasibility and Zoning Review (1–2 Months)

Before you build anything, you need to know what’s allowed. LA’s zoning rules are detailed and site-specific.

Key factors reviewed:

• Zoning classification (e.g., R1, RD2, RE)

• Floor Area Ratio (FAR)

• Setback and height limits

• Slope/hillside overlays or special plans

• Historical and environmental restrictions

Tip: A land use consultant or zoning expert can help you avoid costly mistakes at this stage.

Architecture and Design (2–4 Months)

Once you know what’s possible, you’ll work with an architect to draft your home’s layout and look. This includes:

• Site plan and floor plan

• Engineering (structural, MEP, soils, etc.)

• Energy and green building requirements (Title 24)

1.3 Permitting and Plan Check (3–6 Months)

This part often takes longer than expected. Your plans must go through:

• Planning Department (if needed)

• LADBS Plan Check

• Public Works, Fire, and other departments

• Corrections and resubmittals (usually 1–2 rounds)

For by-right homes with no variances, it could take ~3 months. But hillside homes or homes in special zones could take up to 6+ months.

Phase 2: Construction (9–18 Months)

Now that you have your permits, construction begins. But even here, delays can happen.

2.1 Site Work and Foundation (1–2 Months)

• Grading and soil prep

• Utilities and trenching

• Foundation pouring

This phase varies depending on topography and lot conditions. Hillside or narrow lots = slower start.

2.2 Framing and Structure (2–4 Months)

• Wood/steel framing

• Roofing and waterproofing

• Window and door installation

Your home starts taking shape in this stage, often called the “shell” or “dry-in” phase.

2.3 Rough-Ins and Systems (1–3 Months)

• Electrical, plumbing, HVAC, gas lines

• Fire sprinklers and alarm systems

• Inspections between each major step

LA requires multiple inspections at this stage, which can slow things down if schedules don’t align.

2.4 Finishes and Exterior (3–6 Months)

• Drywall, tile, cabinetry, painting

• Flooring, fixtures, final appliances

• Driveway, fencing, and landscaping

Most delays at this point come from subcontractor coordination, backordered materials, or weather.

Phase 3: Final Inspections and Move-In (1–2 Months)

After construction, your team schedules final inspections with LADBS and other departments. Once everything clears, you receive a Certificate of Occupancy (CofO).

No CofO = no legal move-in.

This process is usually straightforward, but small corrections (like missing signage or incomplete landscaping) can trigger delays.

So, How Long Does It All Take?

Let’s put it all together:
