New Construction Permit Timeline — California, LA & Bay Area

The full permit path — every stage

Most owners think of 'the permit' as a single event. In practice the path is a sequence of dependent stages, each with its own realistic range. Skipping any of them does not save time — it just moves the work later in the schedule, usually at higher cost.

• Feasibility review

  Written zoning / FAR / overlay / utility review against the specific lot — typically 1–3 weeks.

• Property address intake

  APN pull, jurisdiction confirmation, zoning record, prior permit history — days.

• Boundary + topographic survey

  Required on virtually every ground-up project — typically 2–6 weeks.

• Concept design

  Schematic plans aligned to the realistic envelope — 4–10 weeks.

• Architecture (design development)

  Full coordinated architectural package — 8–16 weeks.

• Structural engineering

  Lateral, gravity, seismic, coordinated with foundation and civil — typically overlapping with design development.

• Civil engineering

  Grading, drainage, retaining, stormwater — overlapping with architecture and geotech.

• Geotechnical investigation

  Required on most hillside, expansive-soil, or fill parcels — 4–10 weeks including report — see geotech page.

• Title 24 / energy

  Energy modeling and compliance package — typically 1–3 weeks once architecture and MEP are stable.

• Planning review (where required)

  Discretionary planning, design review, hillside review, coastal review — 2–12+ months depending on jurisdiction.

• Building plan check

  Plan-check submittal, plan-check rounds, and correction loops — typically 2–6 months depending on city and submittal quality.

• Corrections

  Comment response cycles — cycle count is the single biggest schedule lever once the package is in.

• Clearances

  Fire, public works, utilities, school fees, and other interagency clearances — weeks to months.

• Permit issuance

  Building permit issued once plan check is approved and clearances are complete.

• Demolition permit (if applicable)

  Separate permit with hazmat survey and utility disconnect verification.

• Grading permit (if applicable)

  Separate permit on hillside, large grading, or earthwork-quantity projects.

• Construction inspections

  Phase inspections through framing, MEP, final — sequenced into construction.

• Final sign-off / closeout

  Final inspection, certificate of occupancy, and recorded closeout.

City of Los Angeles (LADBS)

City of LA new-construction permits run through LADBS for building plan-check and through LA City Planning for zoning and discretionary review. LADBS publishes plan-check status tools and standardizes correction comment formats; planning timelines vary sharply by case type and overlay. Typical custom-home permit-path ranges in the City of LA land 6–14 months from intake to permit issuance for projects with no discretionary planning, longer when planning entitlements are required.

Independent LA County contract cities

Beverly Hills, Santa Monica, Pasadena, Glendale, Burbank, Culver City, West Hollywood, Manhattan Beach, Long Beach, Malibu, and many other cities run their own building and planning departments. Each has its own correction rhythm, design-review process, and hillside / coastal / historic rules. Some cities are faster than LADBS for straightforward projects; many run longer on anything that triggers design review. We name the specific city's typical range in the feasibility note rather than generalizing.

Bay Area cities — DBI, Peninsula, East Bay, Marin

San Francisco DBI is one of the most demanding plan-check processes in California; SF custom homes typically run 10–18 months from intake to permit issuance, longer when discretionary review at the Planning Commission is triggered. Peninsula cities (Palo Alto, Menlo Park, Atherton, Los Altos, Portola Valley, Hillsborough, Woodside) run discretionary architectural and design review for most new homes, with neighbor-notification and tree-protection windows. East Bay and Marin cities (Oakland, Berkeley, Mill Valley, Tiburon) add hillside, seismic, and view-corridor reviews where applicable.

Hillside, coastal, fire, and historic overlays

Overlays add review tracks. Hillside ordinances (LADBS Hillside, Beverly Hills, Malibu, Santa Monica Mountains) add grading, slope-stability, and drainage review. Coastal Zone parcels trigger Coastal Commission appeal jurisdiction. Very-High Fire Hazard Severity Zone (VHFHSZ) parcels add Chapter 7A envelope review and fire-department access review. HPOZ and historic districts add design review and material-restoration review. Each overlay adds calendar — not weeks, months.

Fire rebuilds — streamlined recovery tracks

LADBS operates a Recovery Permitting Center for Palisades-area parcels, and LA County operates a Unified Permit Center for Altadena/Eaton-area parcels — both offer streamlined paths when the rebuild stays within defined like-for-like parameters. Revised designs step out of the streamlined track and add planning review time. Bay Area and Sonoma fire rebuilds run through the local building and planning department's recovery process.

Small multifamily (2–6 unit) timing

Small multifamily entitlement varies sharply by jurisdiction and the streamlining pathway used (SB 9, density bonus, SB 35 / SB 423, AB 2011). Ministerial pathways shorten planning calendars dramatically; discretionary review can take 6–18+ months on contested infill projects. Construction permits run alongside the same building-department processes as single-family but with additional life-safety and accessibility review.

Where the calendar actually slips

• Plan-check correction cycles

  Cycle count is the single biggest schedule lever. Clean submittals and disciplined correction responses save months.

• Discretionary planning

  Hearings, appeals, and neighbor-notification windows are calendar — not effort.

• Utility coordination

  Service-panel upsizing (LADWP/SCE/PG&E), sewer lateral, and water-service upgrades can add months.

• Owner decisions

  Late finish, fixture, or AV decisions create change orders that ripple into plan-check or inspection.

• Engineering coordination

  Misaligned architecture / structural / civil / Title 24 packages drive correction cycles.

Frequently asked questions

How long does it take to get a custom-home permit in Los Angeles?

Typical range: 6–14 months from intake to permit issuance for City of LA (LADBS) custom homes with no discretionary planning entitlement; longer when planning entitlements, hillside, coastal, HPOZ, or other overlays apply. Contract-city ranges vary by jurisdiction and are named in the feasibility note.

How long does a Bay Area permit take?

San Francisco DBI custom homes typically run 10–18 months from intake to permit issuance, longer when Discretionary Review at the Planning Commission is triggered. Peninsula cities with mandatory architectural review run 6–14 months; East Bay and Marin hillside add additional review time.

Can you guarantee a permit timeline?

No — permit timing is controlled by the city, not the contractor. We name the realistic range in writing during feasibility and sequence the project around the calendar instead of against it. Any contractor promising a fixed permit date on a discretionary project is overselling.

What is the fastest path for a fire rebuild?

Streamlined recovery tracks: LADBS Recovery Permitting Center (Palisades area), LA County Unified Permit Center (Altadena/Eaton area), and equivalent local programs for Bay Area / Sonoma rebuilds. Like-for-like rebuilds qualify for the fastest paths; revised designs add planning review time.

How long does plan check take?

Typical range: 2–6 months across most California jurisdictions, depending on city, submittal quality, and overlay reviews. Correction cycle count is the single biggest schedule lever — clean submittals save months.

Do hillside projects take longer?

Yes — hillside review, geotech coordination, civil/drainage review, and fire-access review all add calendar. Hillside permit paths typically add 3–6 months over a flat-lot equivalent.

When can construction start?

After permit issuance and any required pre-construction inspections or staging approvals. Demolition (if applicable) is a separate permit and runs ahead of the construction permit.

Does design-build shorten the permit timeline?

Indirectly — design-build does not shorten city review, but disciplined coordination across architecture, engineering, and consultants reduces correction-cycle count, which is where the calendar actually slips.
