Washington ADU contractor and property planning.

A backyard building and a conversion are different jobs.

What stands out around Washington.

Washington is identified in City CDBG mapping and includes established housing near major roads. The area label helps locate the property, while permit history and a field walk establish what was actually built at the address.

A few wide photos make the first call useful.

How we would walk a Washington property.

Washington homes may show additions, garage changes, patched openings, roof breaks, and upgraded panels from different periods. We compare those clues with available records before assuming where original structure ends. The site walk also measures driveways, yard depth, service equipment, trees, drains, and the occupied-home entrance. A route that passes a pickup may still fail for long framing or concrete, so deliveries and waste are tested by phase.

A conversion depends on the garage's present slab, framing, roof, moisture, openings, and services. An attached ADU creates new structural and weatherproofing connections at the house. A separate unit introduces foundation, trenches, drainage, and restoration across the yard. The estimate should identify investigation, access labor, dust and weather protection, matching repairs, allowances, and exclusions for the chosen approach. Visible patches direct questions but do not provide the final concealed-condition answer.

Bring permit history and photographs of every roof transition, opening, panel, addition, garage wall, driveway, tree, and family route. Tell the contractor which rooms and parking remain in use. A useful proposal names its drawing version, service assumptions, responsible reviewers, inspections, selections, and closeout. If selective demolition reveals different construction, the written change should state the work, price, and schedule effect before proceeding beyond the discovery.

Washington turnover should inspect opened or patched older construction, roof junctions, garage changes, panels, paving, trees, and the household path against the agreed finish standard.
