Frequently Asked Questions

What are impact fees?

One-time fees charged by municipalities for each new unit to fund infrastructure capacity impacted by the project. Categories: schools, roads, parks, water/sewer, public safety. Vary by jurisdiction — California: $10k-$50k/unit; Texas: $3k-$15k; Florida: $5k-$30k.

Total fee burden?

Typical new multifamily: $10-35k/unit in impact fees. Single-family: $15-60k. In-lieu of affordable housing can add $25-150k/unit. Impact fees + permit fees + planning = 3-8% of development budget in most jurisdictions.

Reducing fees?

Impact fee credits (donations of land, infrastructure). Development agreement negotiation. Affordable housing exemptions. Transit-oriented development credits. Nexus challenges (fee not rationally related to impact). Each requires legal strategy; savings can be material.
