Lancaster ADU Permit Fees & Cost Calculator
Lancaster’s official city fee schedule shows standard building permit charges that would apply to ADU work, including residential new construction at $0.45 per square foot with a $150 minimum and renovations/alterations based on project valuation tiers. The city also charges a mandatory state education fee of $4.50, but I did not find an ADU-specific city fee or a clear utility/school impact fee schedule tied to ADUs in the provided official sources.

Fee overview
Lancaster, Pennsylvania is not a California city, so California ADU impact-fee rules do not apply.
I did not find a city-specific ADU fee schedule or a direct official utility/school impact fee for ADUs in the provided sources; those items may need separate verification with the city, school district, and utilities.
Some official fee lines are classification-dependent, so the permit fee for an ADU conversion versus a new detached unit may differ.
The ADU would be permitted through the City of Lancaster rather than Lancaster Township or another jurisdiction.
The ADU would be treated as residential work unless the city classifies it differently based on use, occupancy, or zoning.
Only official city fee data was used for numeric fee fields; no exact utility connection, school, or impact fees were confirmed from official sources in the provided results.
FAQs
Are Lancaster ADU fee estimates official?
No. ADUFee.com provides planning estimates only. Final fees are set by the city, utility providers, school district, and other agencies.
What sources are used for Lancaster?
The database stores city, state, utility, school, county, and other source links where available. Each estimate should still be verified locally.
Can ADU fees vary within Pennsylvania?
Yes. Permit, utility, school, inspection, and impact fees can vary by jurisdiction, parcel, project size, utility provider, and local interpretation.
