Building department
- Address
- 650 Merchant Street, Vacaville, CA 95688
- Phone
- (707) 449-5152 (Building Division); (707) 449-5140 (Community Development); (707) 317-1070 (Building Inspection Line). The city also publishes an automated building inspection system alongside a toll-free number, 866-752-4311; this record does not state what that number does because the page describing it was not opened.
- Office hours
- FOUR SCHEDULES AND A NINE-DAY FORTNIGHT. "Monday through Friday (closed every other Friday and City Holidays)". "Office Hours: 8:00 AM - 5:30 PM". "Permit Counter Hours: 8:30 AM to 12:00 PM and 1:00 to 5:00 PM (Permit applications and payments accepted until 5:00 PM every day)". And a standing weekly closure: "The Building Division counter is closed on Tuesdays from 3:30 PM - 4:30 PM for a weekly staff meeting." The counter opens half an hour after the office and shuts half an hour before it. The city does not publish WHICH Fridays are closed. It also asks you to book: "We encourage you to call and schedule an appointment to speak with staff. Walk-ins are welcome and will be assisted between appointments." NOTE ALSO THE DOMAIN: cityofvacaville.com redirects to cityofvacaville.gov, while the older permit portal still sits on the .com host.

Codes adopted
California publishes its building standards as Title 24, adopted by state agencies and republished on a three-year cycle. A city or county may change those standards only after its governing body makes an express finding that the change is reasonably necessary because of local climatic, geological, or topographical conditions, and no change becomes operative until the finding and the change have been filed with the California Building Standards Commission.
- THE DIVISION STATES ITS REMIT AGAINST TITLE 24: "The Building Division implements and enforces the State of California's Title 24 California Code of Regulations, including local amendments."
THE 2025 NOTICE IS CORRECT AND WELL DATED: "On July 1, 2025, the California Standards Commission published the 2025 Triennial Edition of the California Building Standards Code (CBSC), Title 24 of the California Code of Regulations. Show full textShow less
THE 2025 NOTICE IS CORRECT AND WELL DATED: "On July 1, 2025, the California Standards Commission published the 2025 Triennial Edition of the California Building Standards Code (CBSC), Title 24 of the California Code of Regulations. State law mandates that local jurisdictions, such as the City of Vacaville, implement the recently adopted codes by January 1, 2026." The city adds the purpose: the updates "are intended to improve fire, life, and safety requirements for new and altered structures and to further conserve energy and reduce emissions."

BUT THE ENUMERATED PART LIST BENEATH IT IS THE 2022 CYCLE, part by part, with 2023 errata attached - Administrative, Building Volumes One and Two, Residential, Electrical, Mechanical, Plumbing, Energy, Historical, Fire, Existing Building, Green Building Standards and Referenced Standards. Read on 2026-09-20 the 2025 codes have been in force for nearly nine months while the itemised list still describes the superseded cycle. Both are recorded as published; see tipsAndGotchas.

PART 7 IS EXPLAINED RATHER THAN LEFT BLANK, and the explanation is useful: "PART 7 - Vacant - formerly California Elevator Safety Construction Code (see Cal. Code Regs., Title 8)". Other records in this corpus disagree about Part 7 - San Mateo lists it as vacant, Roseville and Victorville list a Wildland-Urban Interface Code as an adopted part. This record reports what Vacaville publishes and does not adjudicate between them; anyone relying on a part number should check it against the Building Standards Commission rather than against a city page.
- A NON-TITLE-24 CODE IS ALSO ADOPTED: the "2021 International Property Maintenance Code", listed alongside the California codes. The IPMC is a separate model code and is not part of Title 24, so its presence is a local choice rather than a state mandate.
- Health & Safety Code 18938(b) provides that building standards in the California Building Standards Code "shall apply to all occupancies throughout the state and shall become effective 180 days after publication."
Permit types & fees
Vacaville's permit history isn't searchable here yet
This page covers what the permit requires. What we don't have for Vacaville yet is the record of permits actually issued — the history you'd search by street address. That is a gap in our coverage, not a statement about any particular property.
Your email, and the place — never an address. We only use it to tell you when Vacaville lands. Privacy.
Tips & gotchas
- THE 2025 NOTICE AND THE 2022 PART LIST SIT ON THE SAME PAGE, AND ONLY THE NOTICE IS CURRENT. Vacaville correctly states that the 2025 Triennial Edition was published on 1 July 2025 and must be implemented by 1 January 2026 - and then, immediately beneath, enumerates the full 2022 Title 24 part list with its 2023 errata. Read nine months after the 2025 codes took effect, the itemised list a designer is most likely to click through describes the superseded cycle. This is the same shape as Hesperia, where a 2023 effective date heads a list of 2025 editions: the summary sentence and the detailed list are maintained on different clocks, and the detailed list is the one that looks authoritative.
- VACAVILLE AND FAIRFIELD - NEIGHBOURING SOLANO COUNTY CITIES - PUBLISH NEARLY THE SAME HOURS ARCHITECTURE, and it is worth noting as an observation of two rather than a regional rule. Both work a nine-day fortnight closed every other Friday; both close the counter weekly for a staff meeting (Vacaville Tuesdays 3:30-4:30 PM, Fairfield Wednesdays 8:00-9:30 AM); both run the counter on a narrower span than the office; and both tell applicants that an inspection preference is not a promise in almost the same words. Two cities is an observation, not a pattern - but if you work across Solano County, expect the shape.
- NEITHER CITY PUBLISHES WHICH FRIDAYS ARE CLOSED. An alternating closure is only usable with a calendar, and in both Vacaville and Fairfield the calendar is the missing half. It is the single most call-worthy fact on either page.
- THE COUNTER OPENS AFTER THE OFFICE AND SHUTS BEFORE IT - 8:30 to 5:00 against 8:00 to 5:30 - but payments run late: "Permit applications and payments accepted until 5:00 PM every day". So the last half hour of the office day is for neither counter service nor payment, and the middle of the day has a full hour's break the office does not.
- eTRAKiT RUNS ON TWO DIFFERENT HOSTS HERE, one of them on the city's OLD domain. The city links an eTRAKiT instance at vcvll.csqrcloud.com and a second at permits.cityofvacaville.com, while the main site has moved to cityofvacaville.gov. Anyone holding a saved link or an old confirmation email may be looking at a different instance from the one staff mean. Note too that eTRAKiT appears across this corpus in three states at once - live in Napa and here, retired in Richmond - so the product name alone identifies nothing.
- PART 7 IS EXPLAINED HERE AND CONTRADICTED ELSEWHERE IN THIS CORPUS. Vacaville publishes "PART 7 - Vacant - formerly California Elevator Safety Construction Code (see Cal. Code Regs., Title 8)", San Mateo also lists Part 7 as vacant, and Roseville and Victorville both list a Wildland-Urban Interface Code among their adopted parts. Three cities, two accounts. This record does not resolve it - if a part number matters to your submittal, check it against the Building Standards Commission rather than against any city's page, including this one.
- A MODEL CODE FROM OUTSIDE TITLE 24 IS ADOPTED: the "2021 International Property Maintenance Code". The IPMC governs the condition of existing buildings and is not part of the California Building Standards Code, so it is a local addition rather than a state requirement - and it is the kind of code that bites on an existing property long after construction is finished.
- THE DEVELOPMENT IMPACT FEE MATERIAL IS OLD BY ITS OWN LABELS: a "2022 Development Impact Fees" schedule and a "1992 Development Impact Fee Study" behind it. A fee schedule four years old and a nexus study thirty-four years old are both worth confirming before they are used in a budget.
- WALK-INS ARE ACCEPTED BUT QUEUE BEHIND APPOINTMENTS: "Walk-ins are welcome and will be assisted between appointments." That is a middle position in this corpus - Richmond and Carlsbad require an appointment for a new submittal, Clovis and Hesperia take you at the counter, and Vacaville will see you when there is a gap.
