Carry an ADU from board installation through finish

An accessory dwelling has rooms, openings, and finish choices that need to come together before the walls close in. If the plan stops at board, taping and finishing can fall outside the schedule the project is working toward.

Solis installs ADU drywall from the room layout and drawings, then carries the work through taping and the selected finish. Those stages connect the wall surfaces to the dwelling's planned layout and target schedule.

  • ADU board installation tied to the room layout.
  • Taping and finishing carried into the project sequence.

Here’s how we get it handled

  1. Text us photos or call

    A close-up, a wider view and your city give us a useful starting point. You can also call and talk through the work.

  2. Agree the scope and schedule

    We review the work with you, arrange a site visit where needed and put the agreed scope and finish in your estimate.

  3. Get the space finished

    Solis completes the agreed work and reviews the finish with you. Include interior painting in the scope for a complete drywall-and-paint handoff.

Chehalis two ADU use types

The use chart lists detached and attached or internal ADUs separately, with different parking rules, both allowed in R-1, R-2, R-UGA, R-3, R-4 and EPF. Ordinance 1122B and 1125-B.

Chehalis detached versus internal scope

A detached ADU is a small separate structure. An internal or attached ADU shares walls and often a ceiling plane with the house, so the finish has to run across the join.

The use chart lists detached and attached or internal ADUs separately, with different parking rules, both allowed in R-1, R-2, R-UGA, R-3, R-4 and EPF. Ordinance 1122B and 1125-B. Washington State Legislature: RCW 36.70A.635 (middle housing) and 36.70A.680 (ADUs)

Chehalis ADU attachment typeThe join decides the work

A detached ADU is a small separate structure. An internal or attached ADU shares walls and often a ceiling plane with the house, so the finish has to run across the join.

Chehalis splits ADUs into two uses with two parking rules

The city's use chart lists a detached ADU and an attached or internal ADU separately. The detached type requires no parking within half a mile of transit and two spaces otherwise, while the attached type requires none near transit and one otherwise. Both are allowed in R-1, R-2, R-UGA, R-3, R-4 and EPF. Ordinance 1122B sections 23 and 24 (2025) and Ordinance 1125-B (adopted 2026-07-27). Approved plans and the local authority determine the requirement; Solis scopes the listed drywall work and coordinates the relevant handoff.

Which type you build changes the drywall scope

A detached ADU is a small separate structure with its own ceiling, insulation and service runs. An internal or attached ADU shares walls, floors and often a ceiling plane with the main house, so the board has to tie into an existing assembly. That difference decides how the board ties in and how the finish runs across the join.

What changes the estimate?

Access, occupied-room protection, substrate condition, ceiling height, and the requested finish all change the work sequence in Chehalis, Washington. Send photos, dimensions, and the drawings or finish notes already available so Solis can separate visible drywall work from questions for the designer, inspector, or another specialist. For an ADU, the approved wall and ceiling details control fire, sound, and air-sealing questions; Solis prices the listed drywall work without promising a permit or inspection result.

Common questions

What should I send for a Chehalis adu drywall estimate?

Send wide and close photos, room dimensions, ceiling height, access notes, and the finish or project documents you have. Those details help us identify the practical next step before a site review.

What is outside a Chehalis drywall estimate?

Design approvals, permit decisions, hazardous-material testing or abatement, structural engineering, restoration drying, and other specialist work remain separate when the project requires them. We identify that boundary before pricing the drywall scope.
