Methodology

How we calculate kitchen remodel costs

The calculator is a transparent five-input model. Every number it uses is published below. Updated quarterly against new closed-bid data.

The model

For a given kitchen, the estimated fixed-bid range is calculated as:

fixed_bid = (sqft × tier_per_sf × region_multiplier)
            + layout_change_addon
            + permit_fees

Per-square-foot tier ranges

Tier	Per sq ft (low)	Per sq ft (high)	What's included
Economy refresh	$180	$230	Cabinet refacing or paint, entry-grade quartz, LVP flooring, fixture swap.
Mid-range	$320	$480	Semi-custom shaker cabinets, premium quartz, engineered hardwood, full electrical + plumbing rough-in.
Premium / custom	$620	$980	Custom inset cabinets, Calacatta-quartz or natural stone, structural changes, premium fixtures.

Regional multipliers

Region	Multiplier	Why
Ventura County (inland)	1.00×	Baseline.
Ventura County (coastal)	1.07×	Marine-grade hardware, moisture control, Coastal Commission-related rework risk.
Greater LA (inland)	1.04×	Slightly higher trade labor rates.
LA Westside / Beach Cities	1.18×	Premium labor markets, parking restrictions, HOA reviews, coastal-zone overlap.
Other Southern California	1.02×	Catch-all for OC / IE / SD.

Layout-change add-ons

Layout	Add-on (low)	Add-on (high)
Same layout	$0	$0
Move sink or appliances	$2,400	$4,800
Remove a wall (structural)	$9,800	$22,400

Wall removal includes engineering, LVL beam, posts, drywall finishing, additional plan check time.

Permit fees

When permit-required is checked, $1,400–$3,200 is added. This range reflects published fee schedules across Simi Valley, Thousand Oaks, Moorpark, Camarillo, Oxnard, Ventura, and Ojai for typical kitchen-only scopes (verified April 2026). Cities with more complex plan review (Thousand Oaks, Camarillo) trend high; smaller municipalities trend low.

Data sources

Anonymized real-bid data from completed Southern California kitchen projects, 2024–2026. Each input maps to closed bids with line items.
Per-city published permit fee schedules, retrieved April 2026, verified by phone with each city's planning desk.
Local cabinet, counter, and fixture supplier price quotes (Q1 2026).
Cross-referenced against Houzz Kitchen Remodel Cost study (2025) and Remodeling Magazine's Cost vs. Value Report — Pacific region.

What the model does NOT include

Architect or kitchen designer fees ($2.5K–$8K), if hired separately.
Appliance purchase (homeowner-supplied, varies $4K–$30K+).
Structural engineering for non-load-bearing changes.
Whole-house electrical panel upgrades ($3K–$8K), if required.
HOA design review fees (vary by community).

Update cadence

Recalibrated quarterly against new closed-bid data. Permit fees re-verified annually or when cities adjust schedules.
