# SoCal Home Build & Remodel Cost Calculator (2026)

An interactive estimator for luxury home builds, remodels, and commercial build-outs across Los Angeles, Orange County, and San Diego. It multiplies project size by 2026 Southern California cost-per-square-foot ranges, then adjusts for tier, metro, and site condition. Educational planning ranges — not a quote.

## How it works

Estimate = size (sq ft) × cost-per-sq-ft range for the selected tier × metro modifier × site modifier. For hotels the unit is cost per key. An optional "all-in" mode layers soft costs and FF&E onto residential construction figures.

- Metro modifiers: Los Angeles ×1.00, Orange County ×0.97, San Diego ×0.95 (residential); San Diego commercial ≈ ×0.92.
- Residential site modifiers: flat lot ×1.00; hillside +15–35% (new build) / +10–25% (remodel); coastal zone +10–25% (new build) / +8–20% (remodel).
- Residential all-in adder (land excluded): new build +25–40%, remodel +18–30% for soft costs, design, and FF&E.
- Always carry a 10–15% contingency.

## Luxury custom home — construction cost per square foot (flat lot, 2026)

Build tier | $/sq ft (construction) | What it buys
High-end production luxury | $850–$1,200 | Stock-plan-derived, large-builder execution, mid-luxury finish package.
Architect-led custom | $1,200–$1,800 | Bespoke design, full custom millwork, premium appliances, integrated AV.
Trophy / no-compromise | $2,000–$3,500+ | Imported stone, museum-grade glazing, signature architect, art-handling finishes.

Land, soft costs, and FF&E typically add 25–40% on top of construction. Hillside adds ~15–35%; Coastal Commission jurisdiction adds ~10–25%.

## Luxury home remodel — cost per square foot (2026)

Remodel scope | $/sq ft | What it covers
Cosmetic refresh | $150–$350 | Finishes, paint, flooring, fixtures, light kitchen/bath updates — no structural change.
Full whole-home renovation | $350–$700 | New kitchen and baths, reconfigured layout, new finishes and systems throughout.
Down-to-studs / structural + addition | $600–$1,100+ | Gut renovation, structural work, new MEP, square-footage addition.

Kitchens and bathrooms concentrate the highest cost per square foot. Interior design fees typically run 10–18% of construction; FF&E is additional.

## Commercial build-out — cost per square foot (LA / OC baseline, 2026)

Space type | Tier | $/sq ft
Restaurant | Fast-casual / QSR | $150–$300
Restaurant | Full-service | $300–$550
Restaurant | Fine-dining / chef-driven | $550–$1,000+
Cafe | Kiosk / compact | $150–$300
Cafe | Full cafe | $250–$450
Cafe | Roastery-cafe | $400–$700
Office TI | Spec suite | $40–$90
Office TI | Creative office | $90–$175
Office TI | Executive HQ | $175–$350+
Retail | Standard inline | $100–$250
Retail | Elevated boutique | $250–$500
Retail | Luxury flagship | $500–$1,500+
Boutique hotel (per key) | Refresh / soft-goods | $25k–$75k
Boutique hotel (per key) | Full renovation | $150k–$450k
Boutique hotel (per key) | Ground-up | $450k–$1M+

San Diego commercial typically runs ~8% below LA/OC on labor.

## What moves the number most

Square footage sets the scale; these decide where in the range you land: structural sophistication (open spans, cantilevers, frameless glazing add $80–$200/sf), stone & slab budgets, glazing system tier ($150–$400/sf swing on glass-heavy homes), integrated systems (Crestron/Lutron/climate/shade at $80–$150/sf), and custom millwork volume. The biggest budget-killer is change orders — field-driven changes commonly cost 5–10× the same scope priced up front, which is why resolving the design in a photoreal digital twin and walking it in VR before construction protects the budget.
