What this due-diligence check covers
Minimum lot size controls eligibility; setbacks and buffers control where improvements may go; frontage or width rules can affect access and lot status.
Use the actual legal boundaries and proposed structure, not a rough listing sketch.
Why it matters before closing
These standards interact with wells, septic areas, driveways, slopes, utilities and fire access, so a simple rectangle calculation may be misleading.
What to verify
- List front, side, rear and special setbacks.
- Confirm how frontage and lot width are measured.
- Plot easements, buffers and no-build areas.
- Test the home, driveway, septic and reserve area together.
Red flags that deserve follow-up
- Irregular or flag-lot geometry.
- Setbacks measured from road centerline rather than property line.
- Corner-lot rules creating two front yards.
- Environmental buffer through the widest area.
Evidence to keep in the parcel file
- Survey or scaled concept plan
- Applicable dimensional table
- Agency interpretation for unusual lot shape
- Septic and access concepts
Questions to ask before the deadline
- How is frontage measured?
- Which property line is the front?
- Do streams or roads add extra setbacks?
- Can accessory structures sit in setbacks?
- What is the minimum buildable envelope?
