Summary
Vallejo caps lot coverage, the share of a lot's area covered by building footprints, at 50 percent in the Residential Low Density (RLD) district, 60 percent in Medium Density (RMD), and 75 percent in High Density (RHD), per Chapter 16.202's development tables, while Section 16.104.09 defines exactly which structures count toward that percentage.
16.104.09 - Determining lot coverage. Lot coverage is the ratio of the total footprint area of all structures on a lot to the lot area, typically expressed as a percentage. The footprints of all principal and roofed accessory structures, including garages, carports, and roofed porches and decks shall be summed in order to calculate lot coverage. The following structures shall be excluded from the calculation: A.Unenclosed, unroofed decks, uncovered patio slab, porches, landings, balconies and stairways less than six feet in height;B.Eaves and roof overhangs projecting up to three feet from a wall;C.Trellises and similar structures that do not have solid roofs; andD.Swimming pools and hot tubs that are not enclosed in roofed structures.E.Dog houses, children's playhouses, garbage enclosures, accessory structures less than one hundred twenty square feet and other similar structures, provided they are less than six feet in height.

Full Breakdown
09 defines lot coverage as the ratio of the total footprint of all structures on a lot to the lot area, expressed as a percentage, summing the footprints of every principal and roofed accessory structure including garages, carports, and roofed porches and decks. The section then lists what is excluded from that calculation: unenclosed, unroofed decks, uncovered patio slabs, porches, landings, balconies and stairways under six feet in height; eaves and roof overhangs projecting up to three feet from a wall; open trellises without solid roofs; swimming pools and hot tubs not enclosed in a roofed structure; and small accessory items such as doghouses, playhouses, and garbage enclosures under one hundred twenty square feet and six feet in height.
202-B raises the ceiling to 60 percent for Residential Medium Density (RMD) and 75 percent for Residential High Density (RHD). 202-C is capped at 65 percent coverage regardless of the underlying district. Because accessory buildings, garages, and roofed porches all count toward the cap, adding a shed or covered patio can push a lot over its limit even if the house itself was built within it.
Violations & Fines
Exceeding the maximum lot coverage for your zoning district without an approved exception under Chapter 16.608 is treated as a Zoning Code violation. The director can issue a written notice under Section 16.615.02(C) ordering the owner to discontinue the noncompliant condition or modify the structure to conform, and unpermitted construction that exceeds the coverage cap is a public nuisance the city may abate under Section 16.615.03, independent of any building-permit enforcement action.
