New Construction Permit Timeline in LA County

The Honest Permit Picture in LA County

Building a new home in Los Angeles County in 2026 is doable. It is not fast. Anyone telling you 6 weeks is selling you something. Here are the real numbers, by jurisdiction, that we see week in and week out.

The Phases

Phase 1: Pre-application research (2–4 weeks) Zoning analysis, easement check, soils report, topographical survey if needed.

Phase 2: Schematic + Design Development (6–10 weeks) Architectural design, structural concept, MEP concept, energy modeling.

Phase 3: Construction Documents (8–12 weeks) Full permit drawings, structural calculations, Title 24, fire sprinkler plans, civil/grading if needed.

Phase 4: Plan Check (4–12 weeks depending on jurisdiction — see below)

Phase 5: Permit Issuance (1–2 weeks after final approval)

Plan Check Timelines by Jurisdiction (2026)

City of Los Angeles: 14–22 weeks for new SFD; longer in hillside zones, coastal zones, or specific plan areas.

Unincorporated LA County (LACBC): 12–20 weeks; longer in fire-hazard areas requiring extra review.

Long Beach: 10–14 weeks.

Pasadena: 12–18 weeks; design review board adds 4–8 weeks if applicable.

Santa Monica: 16–24 weeks; design review board mandatory for most projects.

Beverly Hills: 16–24+ weeks; very thorough review.

Glendale: 10–14 weeks.

Burbank: 10–14 weeks.

Total Pre-Construction Time

For a new home in LA City:

  • 4 weeks pre-application
  • 10 weeks design development
  • 12 weeks construction documents
  • 18 weeks plan check (with one round of corrections)
  • 1 week issuance

Total: ~45 weeks — about 10 months from "go" to permits in hand.

Ways to Compress the Schedule

  1. Pick a pre-cleared lot. Subdivisions with pre-approved infrastructure shave months.
  2. Use a design that's been built before. Some plans have been pre-vetted with the city.
  3. Stay within zoning envelope. Variances add 4–12 months and aren't guaranteed.
  4. Hire experienced consultants. A first-time architect's first set of plans typically gets a fatter set of corrections than a veteran's.
  5. Pre-submit informally. Some jurisdictions allow informal pre-meetings with plan check that catch issues early.

What Slows You Down

  • Hillside review (slope, retaining walls, geology)
  • Coastal zone (CDP)
  • Historic preservation overlay zones
  • Specific plan areas (Hollywood, Venice, etc.)
  • Adjacent neighbor objections triggering hearings
  • Mello-Roos and assessment district complications

Construction Phase

Once permits are in hand:

  • Typical custom new home (2,500–3,500 sq ft): 11–16 months of construction
  • Larger / more complex (4,000+ sq ft, hillside, custom finishes): 14–22 months

Total Project Time

Realistic end-to-end for a custom new home in LA County: 22–36 months from initial concept to keys.

If your timeline is shorter than that, your options are:

  • Spec home in a finished community
  • Major renovation/addition vs. new construction
  • ADU as a faster smaller-footprint solution

Budgeting for the Wait

Carrying costs (loan interest, insurance, property tax, soft costs) on a custom new build typically run $4K–$10K/month. Build that into your project budget.
