Owner-adjacent units and shared building costs

Boston’s STR program distinguishes operating categories and addresses owner-adjacent registrations. Confirm the applicable category and actual unit before assuming a furnished Boston purchase can operate as an unrestricted whole-home vacation rental. Boston Inspectional Services STR program.

Define the property study

For an owner-occupied multifamily building, map each unit and the common systems before allocating costs. An owner’s kitchen remodel should not flow into the guest-unit inventory. A shared roof or heating project needs a separate allocation discussion with the preparer. Keep rental-unit assets, owner-space improvements, and building-wide projects distinguishable in both bookkeeping and the study request.

Records that resolve the main questions

A scoping example

The owner lives on one floor and furnishes another unit for guests. A plumbing contractor works in both units during one visit. Ask for labor and materials identified by work area; splitting the total equally without factual support can obscure the proper scope.

Illustrative documentation scenario; not a completed client study or a savings estimate.

Can the entire building go into an STR estimate?

Only after the scope and applicable use allocation are resolved. Provide the property’s mixed-use facts and have the preparer establish the basis to analyze before component reclassification begins.
