Plano ADU Permit Fees & Cost Calculator
Plano allows residential accessory dwelling/backyard cottage construction subject to building permits and plan review. The city’s published fee schedule shows a valuation-based building permit fee table and a separate residential addition/alteration/backyard cottage fee line, but some exact ADU-specific permit and utility charges still need verification from current city departments.

The calculator uses staged city data from the ADUFee database with visible confidence levels and dated source tracking.
Fee overview
The fee schedule excerpt is truncated, so some amounts tied to the valuation table and trade permits could not be fully reconstructed from the search results alone.
I did not find a clearly published Plano-specific utility connection fee or impact fee for an ADU in the provided official sources; those should be verified directly with the city and utility provider.
Texas does not have a California-style ADU impact-fee baseline, so no California baseline applies here.
A 'backyard cottage' in Plano is the closest city-defined ADU-type project for this fee lookup.
The resident will apply under current city residential permitting rules and not under a separate utility or subdivision process.
The project may also require separate trade permits and possibly utility coordination, but exact charges were not fully visible in the provided official excerpts.
FAQs
Are Plano 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 Plano?
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 Texas?
Yes. Permit, utility, school, inspection, and impact fees can vary by jurisdiction, parcel, project size, utility provider, and local interpretation.
