The 750 sq ft cliff in Burbank
At 751 sq ft, the impact fees above total $7,078. At 750 sq ft, state law (Gov. Code §66311.5) sets them to $0. One square foot can be worth $7,078 here — size your ADU accordingly.
What changes on January 1, 2027
Two state laws rewrite parts of this table. SB 1117 (Chapter 809) re-bases covered impact fees for up to two ADUs on only the square footage above 750 — at 800 sq ft, most impact-fee lines shrink to a 50 sq ft basis. School developer fees and water/sewer connection or capacity charges are not covered and do not change. AB 956 (Chapter 791) makes two detached ADUs per single-family lot a ministerial approval. Details: SB 1117 and the 750 sq ft cliff · AB 956: two ADUs on one lot
Common questions
Are impact fees waived for ADUs under 750 sq ft in Burbank?
Yes. California law (Gov. Code §66311.5) bars local agencies from charging impact fees on ADUs of 750 square feet or less. That applies in Burbank the same as everywhere else in California. At 751 sq ft, the impact fees we have verified for Burbank total $7,078 — the cliff is real here.
Where do these Burbank ADU fee numbers come from?
Every line item links to the official source document — the city or county fee schedule, the school district's developer-fee resolution, or the utility district's charges — with the date we last verified it. We publish no fee modeled, no fee guessed.
