FLOORING
Underlayment installation
Install an underlayment that fits the selected floor covering and substrate. The choice addresses the assembly requirements rather than simply adding another soft layer beneath the finish.
START WITH THE DETAILS
What goes into
the work.
Measure each room and subtract areas outside the work. Record the perimeter separately for trim; layout waste is added to material area, not installation area.
Typical scope to confirm
- Identify the finish-floor system
- Confirm substrate condition and allowable underlayment
- Install seams and perimeter details per selected system

PERMIT PLANNING
Usually cosmetic work
Usually a finish-only scope when the structure, room use and utilities stay unchanged. This is a starting classification, not an address-specific exemption; confirm any related regulated work before starting.
- Opening walls or changing structural support
- Moving or adding wiring, plumbing or ventilation
- Historic exterior restrictions or regulated-material removal
ENGINEERING & DESIGN
Engineering is not usually needed
Engineering is not usually part of this finish-only scope. Stop for review if hidden damage, structural changes or unusual support loads are found.
- New structural work or damaged framing
- Unverified heavy-load support
Confirm requirements with the city or county responsible for the property before work begins. The address, exact scope and adopted code determine the final requirements.
