How SASHKOV helps

Consultant Coordination

Consultant Coordination

SASHKOV defines, contracts, schedules and checks every licensed scope a project needs (survey, geotechnical, structural, civil and MEP) under one contract, with one point of accountability through permit issuance.

Site Investigation & Due Diligence

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.

Feasibility & Regulatory Strategy

Feasibility & Regulatory Strategy

Approvals are the most common source of delay on Northwest projects. SASHKOV sets out the approval path before design dollars are spent and manages it through issuance.

Permit & Construction Documents

Permit & Construction Documents

The documents SASHKOV issues are the record a project is reviewed, financed and built from. Sets follow the US National CAD Standard and are issued under a quality management system aligned with ISO 9001.

Land Use & Entitlements

Land Use & Entitlements

Zoning, land use reviews, partitions, lot divisions and variances. SASHKOV confirms what a site is allowed to become, prepares the application and carries it through review and conditions of approval.

Corrections & Permit Recovery

Corrections & Permit Recovery

Correction letters, stalled reviews, expired permits and stop-work orders. SASHKOV reads every comment, coordinates the responses across disciplines and resubmits until the permit is issued.

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.

How many units can my lot carry under HB 1110 or Oregon's middle housing rules?

It depends on the city, the zone, the lot and what sits on it. A middle housing yield study answers it for your parcel: the units allowed, the split or plat path, utilities and frontage, and the cost and schedule of each option. Buildings beyond four units, or larger than the state exemptions allow, are designed by a licensed architect that SASHKOV brings into the contract.

Can a stop-work order be resolved?

In most cases the path is the same: document what was built, provide the reports the jurisdiction asks for, and submit a permit that legalizes the work or lets it resume. The notice tells us where to start.

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.
