Builder view: Conservative uniform inward buffer at the largest applicable setback (30 ft): ≈ 4,505 sq ft (25.8% of lot). Under-approximates the true asymmetric envelope; edge classification will refine. Resolved setbacks: front 30 ft, side 10 ft, rear 30 ft, corner side 30 ft. The 30% total impervious surface cap (§20-615(e)) allows ≈ 5,247 sq ft, so the setbacks are the binding limit here. That allowance covers house, garage, driveway, patio and walks together, so the house itself will be meaningfully smaller once a driveway is included. Based on Chanhassen single-family residential (RSF, typical) — Chanhassen City Code §20-615 (MunicipalCodeOnline; no global currency date — per-section history only; retrieved 2026-07-25); confirm your parcel's zoning. Governing setback is the shoreland OHWL standard (100 ft, §20-481(a)) — Chanhassen shoreland management — Chanhassen City Code Art. 20-VII, §§20-476–20-490 (MunicipalCodeOnline; retrieved 2026-07-25); no mapped public water reduced the buildable area here, so the OHWL term does not bind.
- Conservative approximation — a uniform buffer at the largest setback; the true buildable area is likely larger.
- Confidence is limited by: the zoning district is assumed (the city’s typical single-family district), not verified for this parcel.
