A preconstruction feasibility study costs 5 to 15 thousand dollars and answers the critical question: can you build what you want, on your lot, within your budget, in a reasonable timeframe? This investment prevents 50 to 100 thousand dollar mistakes.
Zoning and land use (what can you legally build?). Lot coverage, setbacks, FAR calculations. Utility availability and capacity. Soil conditions (general assessment — full geotech if needed). Environmental constraints (protected trees, wetlands, coastal zone). HOA restrictions. Historic preservation overlay. The goal: identify every constraint BEFORE you spend money on design.
Based on your vision, we develop a rough order-of-magnitude budget: construction cost range ($/sqft by project type), soft costs (design, engineering, permits — typically 10-15% of construction), contingency (10-15%), and total project cost. This prevents the #1 renovation disaster: designing a $500K project when your budget is $200K.
Identify the optimal permit pathway: standard plan check vs express. Determine if variances or conditional use permits are needed (adds months and uncertainty). Identify all reviewing agencies (LADBS, Fire, Health, Coastal Commission, HPOZ board). Estimate total permit timeline. This roadmap prevents surprises that add 3-6 months to your schedule.
Every project has risks. The feasibility study identifies and quantifies them: structural unknowns in older homes, potential environmental issues, utility capacity limitations, and neighborhood sensitivity to construction. For each risk: likelihood, cost impact, and mitigation strategy. This is where experienced contractors earn their fee — we've seen these issues before.
The feasibility study concludes with a clear go/no-go recommendation. Go: detailed scope, realistic budget, and achievable timeline. No-go: the project isn't feasible as envisioned — but we provide alternatives (scale down, phase, or redesign). If you proceed: the feasibility study fee is credited toward your construction contract. NP Line Design: $5K-$15K depending on project complexity.
