Estimates are typical ranges for Washington State. Driveway figure is permit fee only — construction costs are separate. Costs vary by county, provider, and site conditions.
Get vendor recommendationsHome Site Pros was founded on a simple frustration: getting a residential lot ready for a building permit should not require coordinating five different vendors, chasing county offices, and hoping nothing falls through the cracks.
We built a free self-serve platform so anyone in Washington State can navigate the land feasibility process confidently — find the right professionals, track their studies, and generate a consolidated permit-ready package without hiring a coordinator.
We serve homeowners planning their dream build, contractors who need a fast feasibility workflow on every job, and real estate agents who want confident buyers and clean closings on land transactions.

Ask us your questionEverything you need to know before submitting your parcel.
It depends on your land. A typical full package includes a geotechnical survey, land survey, septic site evaluation, well site evaluation, and driveway permit plus a consolidated report. We scope exactly what your parcel requires so you never pay for studies you do not need.
Most full feasibility packages are completed within 10-21 business days from the time we kick off field work. Individual studies often come back in 7-10 days. We give you realistic timelines upfront and update you at each milestone.
Almost nobody needs all six. Which studies are required depends on your parcel. If you are connecting to a public water system you will not need a well evaluation, and if you are on municipal sewer you will not need a septic evaluation. We scope exactly what is required for your situation.
