An addition is the one project where zoning can stop you before design starts. We are a licensed contractor in Maryland (MHIC #111971) — we pull the permits through the Howard County Department of Inspections, Licenses and Permits, coordinate the licensed trades, and hand you a written line-item scope before demolition starts.
An addition starts with zoning, not construction: setbacks, lot coverage and height limits get reviewed before a building permit is issued, and in some neighborhoods there is a stormwater or historic review on top. Then come the footing and foundation inspections, which have to pass before backfill. This is the longest-lead permit of any project we do, and it is why we start the paperwork while the design is still being drawn.
Your Columbia permit goes through the Howard County Department of Inspections, Licenses and Permits. We pull it under our license and we hold the inspection schedule — you do not chase inspectors and you do not sign the application.
Columbia is a planned community, and exterior changes generally need approval from your village architectural committee under the Columbia Association covenants — in addition to the Howard County permit. That is two separate approvals on two separate timelines, and the covenant review is the one homeowners forget until it stops them.
Most of Columbia's housing dates from the late 1960s through the 1980s. Kitchens and baths are typically original or once-renovated, and basements were often left unfinished — which is why basement finishing is the most common project we scope here.

Most Columbia projects land in the $180 – $340 / sq ft range. That is a planning range for Howard County, not a quote — your written price comes after a free on-site walkthrough.
Yes. The walkthrough and the written scope are free and yours to keep whether or not you hire us. There is no design fee and no consultation invoice.
The build is rarely the long part — permitting and zoning review are. Expect the approval phase to run in parallel with final design, and expect us to give you a schedule that names the permit milestone rather than hiding it. We will tell you at the walkthrough if your lot has a setback or coverage problem, because that changes the whole conversation.
