Before you buy land
Buying land to build a home in Bellevue: what to check first
A buildable-looking lot is not necessarily a practical building site. The expensive surprises are usually below the headline price: access, utilities, slopes, soils, drainage, trees, and the size of house the rules actually allow.
Reviewed against official sources · August 2026Confirm what can be built
- Zoning, setbacks, lot coverage, height, and any overlays.
- Easements, access rights, and title restrictions.
- Critical areas, steep slopes, streams, wetlands, and buffers.
- Significant trees and likely retention or replacement requirements.
Price the site work
- Water, sewer, power, and communications connections.
- Driveway, right-of-way, drainage, and retaining work.
- Demolition and hazardous-material handling for an existing house.
- Survey, arborist, geotechnical, civil, and environmental studies.
Use a feasibility period
Where the contract allows, give the architect and key consultants enough time to test a realistic concept and flag fatal constraints. A conceptual site plan and preliminary cost range are more valuable than assumptions based on nearby homes.
If the site works, continue with the Bellevue new-house permit process and prepare the project before hiring the full team.
Action plan
Run a real lot-feasibility study
- 1
Obtain title, survey, and parcel information; map easements, access, legal lot status, and recorded restrictions.
- 2
Have the architect test a code-compliant building envelope, driveway, parking, outdoor space, and likely tree-retention scenario.
- 3
Screen critical areas, slopes, drainage, soils, retaining, shoring, and neighboring-tree impacts with the appropriate consultants.
- 4
Request utility availability and preliminary connection assumptions for water, sewer, power, gas, and communications.
- 5
Price demolition, site work, consultants, permits, financing, contingency, and time—not just vertical construction.
- 6
Tie the purchase decision to written feasibility findings and professional advice within the contract’s deadlines.
