Utility Tap Fee Calculator

Utility taps carry large upfront fees. This calculator sums connection costs.

Total tap fees

Per unit total

$15,700

Water + sewer

$1,755,000

How the math works

Per unit = water + sewer + gas/electric + stormwater. Total = per unit × units.

Pay tap fees late rather than early when possible — once paid, capacity is committed to the specific unit count, and scope changes (density up or down) often forfeit the prepaid capacity. Timing tap payments to building permit issuance preserves optionality.

Frequently Asked Questions

Typical ranges?

Water: $2,000-12,000/unit. Sewer: $2,500-15,000. Gas: $1,500-6,000. Electric: $1,000-4,000 (often bundled into utility company charge). Stormwater: $500-3,000. Combined: $7,000-40,000/MF unit.

Capacity vs connection?

Tap fee = connecting meter/line to system. Capacity/impact fee = buying system capacity share. Some jurisdictions separate; others bundle. Full connection cost = tap + capacity + service line + meter + engineering.

Sizing implications?

Larger units (more bedrooms) often pay higher fees (more plumbing fixtures, higher sewer EDU). Class-A with in-unit laundry pays more than standard. Factor unit mix into fee calculations.

How often should I rerun this?

Rerun this calculator whenever inputs change materially — new rent roll data, rate moves, loan balance updates, or quarterly operating data. For active deals, monthly refresh is typical. For stabilized assets under monitoring, quarterly is fine. Treat the output as a decision tool, not a one-time answer — market conditions evolve and so should your analysis.
