Frequently asked questions
- What are development impact fees?
- One-time charges a local government levies on new construction to pay for the off-site infrastructure it creates demand for — roads, parks, schools, fire/police facilities, and water/sewer capacity. They're charged per new dwelling unit and are separate from building permit fees.
- How is ImpactFeeAtlas different from a city's fee schedule?
- Cities publish fees as static PDFs in non-standard formats. We normalize them into one schema — by category, land use, and per dwelling unit — so you can compare jurisdictions directly, with a link to every original source and the effective date.
- Are these the building permit fees?
- No. We cover impact/development fees, water & sewer connection (tap/SDC) fees, and mitigation fees — the capital charges that drive a pro forma. Plan-review and building-permit fees are a separate category we intentionally exclude.
