Show full citationHideDevelopment Services Fee Schedule, Section K footnote (***) attached to the Offices occupancy line. Tenant improvements have no separate permit type, fee table, or timeline in Willcox — the TI percentage adjusts the per-square-foot valuation from which the standard Table 1 Construction Fee (and its 65%/25% add-ons) is then calculated. The footnote's minor/major percentages are quoted verbatim as printed; the City does not further define 'Minor' vs 'Major' tenant improvement anywhere in the published schedule — confirm classification with the Building Safety Division. |
