Maryland Home Services And Local Resources

Maryland homeowners can begin many residential-improvement credential checks with the Home Improvement Commission, while separately regulated trades need their own review. For a Baltimore rowhouse roof, document the visible roof edge, drainage and any historic features before choosing a replacement system. CHAP review may be relevant even when a contractor describes the work as ordinary maintenance. Confirm the parcel's status and the current building-permit requirements rather than relying on an old exemption list. Ask who will protect neighboring property, handle access and photograph concealed repairs. Keep the material specifications and approved scope together so a later change to flashing, coping or rooftop equipment can be reviewed accurately.
