Vallejo Parking, Setbacks and Height: District Standards, Garages and Exceptions

A setback is the distance a building must keep from a lot line. Lot coverage is the share of the lot covered by roofed buildings. Together with height and parking, these numbers decide how many homes physically fit on a Vallejo lot, often more than the density limit does. They are set in the district tables of Chapter 16.202 of the Zoning Code, the general rules of Chapter 16.501 and the parking rules of Chapter 16.508. This page gives the numbers, the ways to change them, and the places where state law sets a different rule. The Vallejo overview has the summary.

Setbacks, Height and Coverage by District

Sources: Vallejo Municipal Code Table 16.202-A and Table 16.202-B. Setbacks in the tables carry note (A), the extra standards listed below each table.

The RR and RLD notes in Section 16.202.02 change the numbers for many older lots:

• Variable side yards. On an interior lot, "One yard: ten feet and the other: five feet plus two feet for each foot of building height over twenty-four feet."
• Narrow lots. A lot with an average width of 45 feet or less needs a side setback of 10 percent of the lot width, or three feet on one side, whichever is greater. On lots under 45 feet wide, an upper story may project up to four feet into the second-story setback for up to 30 percent of the wall below.
• Narrow lots recorded before 1947. On a lot under 50 feet wide recorded before Ordinance No. 15 N.C. of March 19, 1947, a side yard may shrink to 10 percent of the width, at least three feet, if it does not face a street and the building is one story within five feet of the line.
• Porches. Covered walkways, porches and verandas may project three feet into a side setback for up to ten feet of length.
• Rear setback. "In the RLD district, the rear setback may be reduced to ten feet if the rear setback for abutting lots is ten feet."

In RMD and RHD, Section 16.202.03.A.3 allows a smaller front setback on built-up blocks. Where 75 percent or more of the lots on both sides of the street are built on, the setback for an entry stoop or porch is "the average of those on the improved lots or fifteen feet, whichever is less." Where an RMD or RHD lot adjoins RLD, the side setback grows to 10 feet and the rear to 20 feet.

House Design Rules

Section 16.202.03 sets design standards for single unit housing, detached and attached. They matter for duplexes and townhouses as well as single houses.

• Entry. The main entry faces the street with a porch or recess "with a minimum depth of five feet."
• Walls. "No street-facing facade shall run in a continuous plane of more than twenty-five feet without a window or a minimum four-foot projection, offset, or recess."
• Garages. An attached garage on the front half of the lot facing a street may be no wider than 50 percent of the front of the building, or 40 percent on lots wider than 100 feet.
• Paving. Paving may cover no more than 50 percent of a required street-facing yard.
• Driveways. "A maximum of one driveway up to 20 feet wide is permitted to serve a single unit." Driveways sit at least 5 feet from side lot lines with a planted strip at least three feet wide.
• Alleys. A detached garage may open onto a paved alley if it sits at least 5 feet back from the rear line.

How Height and Coverage Are Measured

Section 16.104.13 measures a home's height "from the average elevation of that portion of the lot covered by the proposed residential structure or addition to the highest point of the roof," or to the top of a parapet wall. Section 16.104.14 counts a basement as a story when the floor above is more than six feet above natural grade for more than half the building's perimeter. Table 16.501-A lets some features rise above the limit: chimneys and spires 5 feet, elevator and stair towers for multi-unit buildings 12 feet, mechanical penthouses 10 feet, and parapets 4 feet (except on detached homes). No part above the height limit may be used for sleeping quarters.

Section 16.104.09 counts all roofed buildings, garages, carports and roofed porches and decks in lot coverage. It leaves out open decks, patios and stairs under six feet tall, eaves projecting up to three feet, open trellises, uncovered pools, and small structures under 120 square feet and six feet tall. The ADU chapter in force since October 8, 2026 adds that coverage and other site standards may not be applied to stop one detached ADU of 800 square feet with four-foot side and rear setbacks.

Accessory Buildings and Fences

Section 16.501.02 sets the rules for garages, sheds and studios in residential districts. An accessory building up to 14 feet tall goes on the rear half of the lot, at least five feet from the rear line, or three feet if it is more than 50 feet from the front property line. It may have a sink and toilet but no kitchen or shower unless it is an approved ADU. In RLD no accessory structure may exceed 1,000 square feet. A guest house, with sleeping and bathroom space and no kitchen, is permitted in RR, RLD and RMD and needs one parking space.

Table 16.505-A limits fences to 3 feet in a required front yard, or 4 feet with the Traffic Engineer's approval, and to 6 feet in side and rear yards, plus a one-foot decorative extension such as lattice. Hillside parcels have their own fence rule, covered on the historic districts and hillsides page.

Parking Requirements

Sources: Vallejo Municipal Code Section 16.508.04, Tables 16.508-A and 16.508-B, Tables 16.202-A and 16.202-B, and Section 16.215.03; ADU exemptions in Ordinance No. 1890.

Vallejo asks for one space per home in all residential districts. Required spaces in the front half of a lot, or within 25 feet of the side street on a corner lot, must be covered by a garage, carport or roof, with two exceptions: "One uncovered parking space may be provided in the required front yard on a paved pad for an accessory dwelling unit," and uncovered spaces may sit in the rear half of the lot. Parking areas for four or fewer homes may let cars back out into the street; larger ones may not.

The space sizes are in Table 16.508-C. A 90-degree space is 9 feet by 18 feet with a 25-foot aisle, and a parallel space 8 feet 6 inches by 22 feet. Up to 25 percent of required spaces may be compact, 8 by 16 feet. Tandem spaces are allowed when "pairs of spaces in tandem are assigned to the same residential unit," with the stall length doubled.

Ways to Provide Less Parking

• Minor use permit. Section 16.508.04.D allows fewer spaces than the minimum, "including elimination of all parking spaces," with a minor use permit, if the Director finds that measures will reduce demand and that nearby on-street parking will not be "substantially" reduced.
• Mixed-use districts. Section 16.508.14.B lets the Director or Planning Commission waive or reduce parking in NMX, DMX and WMX when the use is within one-half mile of a transit corridor or one-quarter mile of a public parking facility, among other findings.
• On-street credits. Outside those districts, consistently available on-street spaces can count toward the requirement one for one, based on a parking study of each block face within two blocks.
• Downtown. Buildings in DMX built before the Downtown Specific Plan of September 2005 are exempt; new homes in DMX Districts 1 to 4 need one space each.
• Transit-oriented projects. Eligible projects within 2,500 feet of the ferry terminal, the transit centers and the Curtola Park & Ride under Chapter 16.215 have no minimum.
• Garage conversions. Under Section 16.608.03, the Director may let a house replace a converted garage with uncovered parking. A new house must be lived in for a year before such an application.

State law goes further near transit. Government Code 65863.2 says "A public agency shall not impose or enforce any minimum automobile parking requirement on a residential, commercial, or other development project if the project is located within one-half mile of public transit," unless the City makes written findings within 30 days of a complete application. Chapter 16.508 does not mention this statute; it controls over the code. The City's May 2026 project list says the Council adopted a parking action plan on March 24, 2026 that proposes zoning changes to eliminate parking minimums within one-half mile of the Vallejo and Mare Island ferry terminals; that zoning text was still to come.

Exceptions to the Standards

Chapter 16.608 lets the Director grant relief "not to exceed twenty-five percent of the requirement" for front, side and rear setbacks, lot coverage, landscaping, parking space dimensions and fences. Height relief is limited to "twenty-five percent or two feet above the maximum building height or other height limitations, whichever is less." The Director may not grant an exception for lot area, width or depth, the number of stories, the minimum number of parking spaces, residential density or floor area ratio. Larger relief takes a variance under Chapter 16.607, decided by the Planning Commission. In historic districts the Director may modify setbacks, height and coverage by up to 25 percent under Section 16.614.08.D to help preserve a historic building.

Where the Code Disagrees With Itself

• RLD rear setback. Table 16.202-A sets the RLD rear setback at 5 feet, while note A.9 says it "may be reduced to ten feet if the rear setback for abutting lots is ten feet," which reads as an increase. The table's 5 feet is the number the code sets; confirm with the Planning Division before relying on it.
• Missing section. Table 16.202-B points to "Section 16.202.04.A.5, Parking Setback," a section the code does not have; the parking setback rule is in Section 16.202.03.A.5.
• Odd cross-reference. Table 16.202-A sends the parking rows to "Section 16.501.05, Height Exceptions."
• State parking law. Table 16.508-B prints parking minimums citywide; Government Code 65863.2 bars them within one-half mile of public transit unless the City makes findings. The statute controls.
