SERVICE

Site Investigation & Due Diligence

Before a purchase, a lease or a design contract, SASHKOV establishes the site as it actually is: its lines, its ground, its utilities, its water and the constraints on it. Each investigation is scoped to the decision in front of the owner and carried out with licensed professionals under one SASHKOV contract.

What this service covers

Site Due Diligence Report

Site Due Diligence Report

One report on what stands between a site and the owner's plans, delivered inside the purchase, lease or financing window. SASHKOV brings the survey, utility locate and environmental work into the contract as the site requires them.

Utility & Service Capacity Review

Utility & Service Capacity Review

Whether water, sewer, power and storm service can reach the site, at what size and at what connection cost. SASHKOV confirms capacity with each provider and brings in utility locating and civil review where the record runs out.

Buildable Area Determination

Buildable Area Determination

Where a building can go once setbacks, easements, slopes and critical area buffers are applied. When the answer depends on exact lines and grades, SASHKOV brings a licensed land surveyor into the contract.

Critical Areas & Geologic Hazard Coordination

Critical Areas & Geologic Hazard Coordination

Steep slopes, landslide areas, wetlands, streams and regulated trees identified before they stop a project. SASHKOV scopes what the code requires and brings the geotechnical, arborist or wetland professional into the contract.

Frequently Asked Questions

Can you tell me whether my project is permittable before I invest in a plan set?

Yes, and we recommend it. A feasibility study is a site visit, a zoning and land use review, a code review against the specific jurisdiction, and a written determination of whether the project as described can be permitted, what it would require, and what would have to change.

The seller told me it was already approved for this. Should I rely on that?

Not without verification. Prior approvals expire, get conditioned, or apply to a use different from yours. We check what is actually on record with the jurisdiction and tell you what carries forward.
