Custom Home Cost Calculator

Home Style

What style of home are you drawn to?

Your architectural style shapes structural costs, materials, and detailing. Start here.

Two-Story Traditional
Classic layout — living spaces down, bedrooms up.
Modern Farmhouse
Board & batten, gabled roof, mixed metal and stone accents.
Ranch / Single Story
Everything on one level — accessible, open, efficient.
Spanish / Mediterranean
Clay tile roof, stucco, archways, wrought iron details.
Contemporary Modern
Clean lines, large glazing, steel accents, low or flat roof.
Size

How large is your home?

Drag the slider to set your finished square footage above grade.

Finished Square Footage

Finish Level

What level of finish are you looking for?

This sets your base cost per square foot. Title 24 compliance and the California solar mandate are included in every tier.

Semi-Custom
Builder-grade finishes with some selection control. Quartz/laminate counters, stock cabinetry, standard fixtures.
Mid Custom
Upgraded finishes throughout. Engineered hardwood, quartz counters, semi-custom cabinetry, designer plumbing.
High Custom
Premium materials, custom millwork, high-spec mechanical, detailed craftsmanship throughout.
Luxury / Architect-Driven
Custom everything — bespoke design, imported materials, no compromises. Includes outdoor & luxury add-ons.
Stories

How many stories?

Two stories is the most cost-efficient — roof and foundation spread over more square footage. Single-story builds carry a per-square-foot premium.

Site

Tell us about your lot.

Two questions that meaningfully affect cost in the Inland Empire: lot grade and fire zone designation.

Terrain & Grade
Flat Lot
Level grade, easy vehicle access. No site modifier.
Sloped
Moderate grade, some retaining. Common in Canyon Crest, parts of Corona.
Steep Hillside
Significant grade requiring engineered retaining and extensive site prep.
Cal Fire Hazard Zone (FHSZ)
Not sure? Check your address on the Cal Fire FHSZ map. Much of unincorporated Riverside County falls in High or Very High zones — Chapter 7A WUI construction is required and adds real cost.
Not in FHSZ
No WUI requirements.
Moderate
Light Chapter 7A upgrades.
High
Full Chapter 7A required.
Very High
Most stringent ignition-resistant assemblies.
