CMM Interior Associates

Designers in Shrewsbury don't pull permits — the contractor does, through the Shrewsbury Building Department. A kitchen or bath remodel typically triggers building, plumbing, and electrical permits, with gas line work needing a separate gas permit. Mid-century homes near the lake and along Main Street sometimes carry undersized 100-amp services and dated panels; a designer planning a kitchen or whole-floor scope will usually have the GC verify service capacity before finalizing a lighting and appliance plan. Shrewsbury does not maintain restrictive local historic districts, so interior design and finish work proceeds without preservation commission review regardless of neighborhood.

Shrewsbury interior designer fees run in the mid-tier band, typically 20 to 30 percent below Greater Boston. Hourly rates from established designers serving the area commonly fall in the $110 to $200 range; flat-fee single-room scopes typically run $3,000 to $6,500. Kitchen-bath selection packages commonly land at $3,500 to $8,000. Whole-house engagements on larger subdivision Colonials or lakefront Quinsigamond properties are usually priced at 10 to 18 percent of the combined construction-and-furnishings budget. Cost-plus procurement markups run 15 to 28 percent over trade. A paint and color consultation typically runs $300 to $700.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential interior design work; ask for the registration number and check it before paying a deposit.
