Custom Home Costs in San Diego and Austin: A Budgeting Guide

The cost to build a custom home depends on the property, the architecture, and what is included in the estimate. At Rick Somers Construction, our homes average approximately 6,000 square feet. A useful budget must reflect that scale, the intended finishes, and the work required beyond the walls of the residence.

Two markets, two different budgets

For the homes we build, North County San Diego is substantially more expensive than Austin. A Rancho Santa Fe or coastal North County project should be evaluated on its own terms, rather than priced using an Austin comparison. Site access, local approvals, construction requirements, trade pricing, and material selections all contribute to the difference.

Even within one market, two homes with the same living area can carry very different budgets. A flat, serviced lot and a hillside property requiring retaining walls do not start from the same position.

Define the complete scope

Separate land acquisition from development and construction. Then identify architecture and interior design, engineering and surveys, approvals and fees, site preparation, utility connections, the residence, and exterior improvements. Pools, guest houses, extensive landscaping, gates, and outdoor kitchens should appear as identified scope rather than disappear inside a headline rate.

The budget should also explain general conditions, contractor fees, allowances, and contingency. General conditions cover project administration and jobsite requirements; contractor compensation should be clearly described in the proposal. A contingency is a reserve for uncertainty, not a substitute for defining the work.

Use cost per square foot carefully

For a 6,000-square-foot home, multiplying the living area by a project-specific construction rate can provide a starting comparison. First establish whether the rate includes garages, covered terraces, detached structures, site work, and professional fees. Without that definition, apparently similar figures may describe substantially different projects.

Ask which selections are priced, which are allowances, and which are excluded. A cabinetry allowance and a fully specified cabinetry package do not provide the same level of budget certainty.

Refine the estimate as the design develops

Early estimates help establish feasibility. Drawings, engineering, finish specifications, and trade input allow the budget to become more detailed. Review changes while the design can still respond, and record their effects on cost and schedule together.

Bring the property address, available plans, approximate size, desired features, and target investment to the first discussion. We can then identify the information needed for a meaningful preliminary budget.
