How long does it take to build a custom home in Los Angeles?

The six stages of a Los Angeles custom home

These are typical ranges for a single-family custom home in Los Angeles. Every property is different, and Ludi provides a project-specific schedule after reviewing the plans and the site.

1. Site review and feasibility

   2 to 8 weeks

   Before design starts, confirm what the lot allows: zoning, setbacks, height limits, hillside or coastal rules, utilities and access. A survey, and on sloped lots an early geology and soils review, prevents designing a house the site cannot support.

2. Design and engineering

   6 to 12 months

   The architect moves from concept to construction drawings while structural, civil and energy (Title 24) engineers complete their work. Bringing a builder in during this stage lets the design be priced and checked for buildability before it is finished.

3. Plan check and permits

   4 to 12 months

   In the City of Los Angeles, plans are reviewed by the Department of Building and Safety (LADBS), often with input from Planning, the Fire Department and Public Works. Each round of corrections adds weeks. Beverly Hills, Santa Monica and unincorporated County areas such as Marina del Rey run their own reviews.

4. Pre-construction

   1 to 3 months

   Final pricing, the construction contract, the schedule and trade commitments come together. Long-lead items such as custom windows, doors, stone and specialty fixtures are ordered now, because some take months to arrive.

5. Construction

   12 to 24 months

   Site work and foundations, framing, rough mechanical, electrical and plumbing, then the exterior envelope, interior finishes and landscaping. The city inspects at each key stage before walls are closed. Size, site complexity and finish level drive where a project lands in this range.

6. Final inspection and move-in

   1 to 2 months

   Final inspections, the certificate of occupancy, a punch list of remaining items and a walkthrough with the owner. Systems are tested and the owner receives warranties and operating information.

What makes a build take longer

• Hillside lots. Geology reports, deeper foundations, grading limits and difficult access add both review time and construction time.
• Coastal properties. Homes in the Coastal Zone can need a Coastal Development Permit in addition to a building permit.
• Design changes after permits. Changing approved plans can mean revisions, re-submittal and re-ordering materials.
• Long-lead materials. Custom windows, imported stone and specialty fixtures can hold up the schedule if they are selected late.
• Incomplete plan sets. Missing engineering or coordination gaps between consultants create extra rounds of plan check corrections.

How to keep a custom home on schedule

Bring the builder in during design, not after permits. Early input on structure, site access and materials catches problems while they are still lines on a drawing. Make the big finish decisions before construction starts so long-lead items can be ordered on time, and agree on how decisions and updates will flow between owner, architect and builder.
