About New Home Construction in Los Angeles

Ground-up work is design-build under one contract: architecture, structural, MEP, civil, LADBS permits, construction, landscape, and closeout. Typical project size $1.2M–$4M+.

Los Angeles permit notes · New Construction

What we resolve before drawings begin.

  • 01

    Full LADBS plan-check + civil

    New construction triggers full LADBS plan-check, civil drawings, grading permit (on sloped lots), and often coastal or hillside review. We coordinate the full set.

  • 02

    Title 24 + CALGreen

    California energy and green-building codes are non-trivial on new construction. We design to them from day one, not retrofit at permit.

  • 03

    Soils, drainage, geotech

    Every new build needs a soils report and engineered drainage. Hillside builds need geotech + caissons + slope stability.

ADU intel · the build stack we ship · Los Angeles spec

A 2025 LA detached ADU is 12–16 weeks of construction over 6–9 months of permit and design. The fastest path is the pre-approved-plan path — when the design fits.

    Mini-split heat pumps for ADU HVAC

    Right-sized inverter heat pumps hit Title 24 and CalGreen with zero ductwork — the cleanest, cheapest HVAC for an ADU < 1,000 sf.

    Tankless water heaters

    Wall-mount tankless saves 9 sq ft of floor and qualifies for SoCalGas rebates when CSA-approved gas units are still permitted; we switch to heat-pump electric where local code requires.

Specification gotchas we resolve before contract.

  1. 01

    Pre-approved plans (LA + city catalogs).

    LA City, Santa Monica, Pasadena, Long Beach all maintain pre-approved plan catalogs. Plan check drops to 30 days or less when the plan is in the catalog.

  2. 02

    Utility separation (SB 9 / AB 2221 nuance).

    Separate utility meters are no longer required to permit, but they're often required for refinance or sale. We pull the right meter strategy for the owner's exit plan.

  3. 03

    Fire setbacks + sprinklers.

    ADUs under 1,200 sf often don't trigger sprinklers; over 1,200 or with specific roof tie-ins, NFPA 13D applies.

Los Angeles · New Construction FAQ

Questions Los Angeles homeowners ask first.

Start an LA new construction brief. We'll review the lot, engage architecture + soils, and write a design-build contract.

  1. What does new construction cost in LA?
    Typical custom single-family new construction in LA runs $550–$1,000 per square foot all-in. Hillside, coastal, and high-finish projects exceed this.
  2. How long does it take?
    Brief-to-keys is typically 22–36 months: 6–9 months design + permit, then 16–24 months construction.
  3. Do you do small developments?
    Yes — 2–6 unit small residential developments (SB-9 lot splits, duplex / triplex infill, small townhouses) across LA.
  4. Can I tear down and rebuild on my existing LA lot?
    Usually yes. We confirm zoning, height limits, lot coverage, and any historic or HPOZ overlays during feasibility before signing the design-build contract.
  5. Do you handle architecture in-house?
    Yes — design-build means architecture, structural, MEP, civil, and construction sit under one contract with one accountable team, instead of bidding plans out to a low-bid GC.
