What matters for project planning
Historic-preservation review is the item that governs this trade, and it is the one worth settling first, because on a designated property window review can reach sash configuration, material and profile rather than merely thermal performance -- and may carry an expectation that original units are repaired. That is determined by address, not by the look of the street. The rest of this framework reaches an opening in a wall hardly at all: karst geology, springsheds and drainage concern the ground, and tree impacts only matter if access equipment has to work under protected canopy.

Verify the property, not just the city
Citywide context cannot establish a parcel’s flood zone, historic designation, stream buffer, permit requirements, soil conditions, or concealed construction. Confirm these details with the right local authority and the chosen provider before any work begins.
