Why it matters to you
If your property sits in the Old and Historic District, Old City District, Landmark Overlay Zone, or Historic Corridor District, new or relocated outdoor equipment falls under BAR review — and on the peninsula, flood elevation rules apply at the same time.
Practical guidance
Plan equipment placement for visibility, flood elevation, sound, and service access before anything is ordered. Ductless mini-splits and slim-duct systems often fit historic homes best because they avoid bulky duct runs.
