FEASIBILITY STUDIES

Frequently asked

• What is included in FEASIBILITY STUDIES?

  Our FEASIBILITY STUDIES scope includes design through completion: feasibility, schematic design, construction documents, permit submittal and review management, construction with one self-performed framing crew plus L&I-licensed MEP subcontractors, all required WA inspections, certificate of occupancy, and warranty. One contract, one license number, one warranty — not a coordination headache across five vendors.

• How is FEASIBILITY STUDIES different from a generic remodel?

  FEASIBILITY STUDIES carries code, permit, and construction details that a one-off remodeler hasn't repeated enough times to optimize. Examples: IECC R406 envelope path selection, fire separation when units are within 5 ft, side-sewer slope requirements, IRC Appendix AQ when permitted as a tiny house, separate utility metering rules. We do this scope every month — repetition is what makes our first-cycle approval rate and our schedule reliability stand out.

• What is the typical price range for FEASIBILITY STUDIES?

  FEASIBILITY STUDIES pricing in 2026 lands $330–$380/sqft all-in depending on size, lot conditions, finish tier, and AHJ. The wide range is real — small lots with difficult access, soils requiring pier-and-beam, or service upgrades push the upper end; flat lots with good access and a catalog plan land at the lower end. Our feasibility report gives you a ±15% number tailored to your specific lot in two weeks.

• What permits does FEASIBILITY STUDIES require?

  Standard FEASIBILITY STUDIES permit stack: building permit (covers structural, mechanical, plumbing under combined review), side-sewer permit, water meter capacity check, electrical permit, drainage review where applicable, addressing application. Critical-areas review triggers on lots mapped for steep slope, wetland, riparian, or landslide hazard. We pull all permits as a pass-through line in our contract — not marked up.

• How long does FEASIBILITY STUDIES take from contract to completion?

  9–14 months end-to-end is typical for FEASIBILITY STUDIES: 6–8 weeks design, 8–16 weeks permit, 18–26 weeks construction. Faster on catalog plans with pre-app meetings. Schedule variance is driven by AHJ workload, owner selection pace, and any field-discovered conditions. We publish a Gantt at contract and update it weekly.

Documented in a written warranty packet at closeout.

• Do you self-perform FEASIBILITY STUDIES work or subcontract everything?

  We self-perform framing, exterior weather barrier, interior trim, and project supervision with W-2 carpenters. MEP trades (plumbing, electrical, HVAC) are subcontracted to L&I-licensed specialty contractors we've worked with 5+ years — WA requires separate PL, EL, HVAC/R licenses that a GC cannot legally self-perform without them.

• What's the change-order policy on FEASIBILITY STUDIES?

  Every change order is written, priced, and signed before work proceeds. We never charge T&M without a not-to-exceed. Owner-initiated changes carry 15% OH&P; field-discovered conditions (rotted sheathing, undocumented buried oil tank, unmapped sewer) are priced at cost +10% with photo documentation. Average FEASIBILITY STUDIES project sees 4–7 change orders totaling 3–6% of contract value.
