Full Breakdown
Section 174.003(K) treats an accessory dwelling unit as a mobile home unit for impact fee purposes, meaning the ADU is assessed its own impact fee separate from whatever was charged for the principal single-family home. Impact fees fund the roads, parks, and utility capacity the additional dwelling unit draws on, and they're calculated using the mobile-home fee schedule rather than the single-family or accessory-structure schedule. Builders should budget for this fee in addition to permit and inspection costs before starting ADU construction.
Violations & Fines
Occupying an ADU before paying the required mobile-home-rate impact fee can delay or block issuance of the certificate of occupancy.
