Construction expenses that aren't physical building work.
Soft costs in construction are expenses that don't result in physical building work but are necessary to complete the project: architectural and engineering design, permits and impact fees, legal and accounting, marketing, financing costs, and developer fees. Soft costs typically range 15–30% of hard costs depending on project type.
Soft cost categories vary by project but commonly include: architectural and engineering (5–8% of hard costs), permits and impact fees (1–5% depending on jurisdiction), legal and accounting (1–2%), financing costs (origination, interest reserve, lender legal — 2–4%), marketing (1–3% on for-sale projects), and developer fee (3–5% of total project cost).
Soft costs are often more variable than hard costs. A jurisdiction with high impact fees and lengthy entitlement processes (some California municipalities) can add 8–12% to a project budget just in permits and approval costs. The same project in a low-fee Midwest jurisdiction might see 1–2%. Always research jurisdictional soft costs early in project planning.
Construction lenders fund soft costs alongside hard costs on most ground-up projects. The loan budget typically includes hard costs, soft costs, and an interest reserve to cover loan interest during construction. Some smaller lenders or value-add bridge programs only fund hard costs and require the borrower to fund soft costs separately. This is a key term to confirm at the loan structure stage.
On fix-and-flip projects, soft costs are typically borrower-paid out of pocket rather than included in the loan budget. The loan funds purchase + hard rehab costs; the borrower pays for architect (if needed), permits, holding costs, and other soft items. This is one reason fix-and-flip operators need significant cash reserves beyond the down payment — soft costs eat real money quickly.

Expenses that don't result in physical building work — design, permits, legal, financing, marketing, developer fee. Necessary to complete the project but not site or materials.
Typically 15–30% of hard costs depending on project type and jurisdiction. SFR is lower (15–25%); commercial is higher (25–35%). High-fee jurisdictions can push higher.
Usually yes on ground-up projects — loan budget includes hard + soft + interest reserve. On fix-and-flip, soft costs are typically borrower-paid separately.
Varies by project. Architectural/engineering is typically 5–8% of hard costs. Permits and impact fees vary 1–10%+ by jurisdiction. Developer fee is typically 3–5% of total project cost. Each major category should be planned separately.
Some — shop multiple architects, use design-build delivery to consolidate engineering, choose jurisdictions strategically. But most soft costs are necessary — cutting them risks delays or design quality.
Matrix structures construction loans covering the full project budget — hard costs, soft costs, and interest reserve. No surprises mid-build.
