Davis Building Permit — Filed & Tracked For You

Davis is a Yolo County city of about sixty-seven thousand residents in the Sacramento Valley, shaped by a large university, a compact bicycle-oriented street grid and strong local design and sustainability policy. Its Building Division, within Community Development and Sustainability at the city offices on Russell Boulevard, is the sole building authority inside the city.

This guide covers the Building Division, the resale certificate programme that catches sellers and buyers, review timing, and the codes in force.

This guide covers work inside the City of Davis limits. Unincorporated Yolo County and neighbouring cities are separate authorities.

What requires a building permit in Davis?

California builds on a single statewide code — the California Building Standards Code, known as Title 24 — adopted on a three-year cycle by the California Building Standards Commission. The 2025 edition took effect on January 1, 2026 and governs statewide. Cities and counties enforce Title 24 and may adopt local amendments, but an amendment must be filed with the state and may only be equal to or more restrictive than the state code, justified by local climatic, geologic or topographic conditions. So the first question in Davis is which authority has jurisdiction — the city on incorporated parcels, the county in unincorporated territory — and what local amendments sit on top of Title 24.

Local amendments and thresholds differ from one jurisdiction to the next, so an exempt list from a neighbouring city is not reliable — a project waved through in one place needs a full permit set in the next. An exemption from a building permit is never an exemption from zoning, the statewide energy or green-building codes, or an electrical or plumbing permit. Confirm scope with Building Division before work starts.

The statewide layers that apply everywhere

Several parts of Title 24 apply on top of the base building code and routinely catch projects owners assume are exempt: the California Energy Code (Part 6), among the strictest in the nation; CALGreen (Part 11), California’s mandatory statewide green-building code; and the accessibility provisions in Chapters 11A and 11B. Seismic design is built into the code statewide, and in fire-prone areas the wildland-urban-interface rules of Chapter 7A and Cal Fire defensible-space requirements add a further layer. In the City of Davis, the Building Division within Community Development and Sustainability administers Title 24 with city amendments, with the 2025 codes applying to building permit applications made from January 2026.

Who handles permitting in Davis?

The Building Division issues construction permits and inspects work inside the city, applying the California Building, Residential, Plumbing, Mechanical, Electrical and Energy Codes as adopted by the city.

Applications are reviewed in the order received, with typical processing of five to ten business days after submission. Permit fees are paid online once the permit number is issued after processing, and cheques are accepted by post or through the drop box at the city offices. Property owners may apply for permits directly using the owner-builder form alongside the correct residential or commercial permit type.

Counter and phone hours end an hour before the offices close, which is the most common reason a same-day question goes unanswered. Confirm the parcel is inside the city, because unincorporated Yolo County and the neighbouring cities file with different authorities under their own amendments.

Permit types

Residential permits

Residential work inside the city is permitted and inspected by the division under the 2025 codes and city amendments. The resale programme is the distinctive layer: a resale inspection application is emailed to the division, a resale number and payment instructions are returned, and corrective work with any required permits is completed before the certificate is validated and passed to the buyer. Owner-builders apply directly using the owner-builder form.

How California contractor credentials work

California licenses contractors statewide through the Contractors State License Board, not locally. The CSLB issues three license types — Class A for general engineering, Class B for general building, and the Class C specialty classifications for individual trades — and a contractor must hold the classification that matches the work. A license is required for any project valued at one thousand dollars or more in combined labour and materials, and, in practice, for any work that requires a permit regardless of value.

Commercial permits

Commercial work goes through division plan check against the California Building Code, the Fire Code, the Energy Code and CALGreen. Applications are reviewed in the order received on the same five to ten business day guideline, and projects that also require planning or design review run those approvals alongside rather than after the building submittal, which is worth sequencing deliberately on any exterior change.

Licenses, trade classifications and design professionals

Practically, three credential layers appear on California projects: a CSLB license in the correct classification for the contractor pulling the permit; the specialty C-classifications for the electrical, plumbing and mechanical trades; and, on commercial and larger residential work, drawings stamped by a California-licensed architect or engineer. Confirm what Building Division requires for the specific building before filing.

Davis permit costs and fees

Budget the city building permit and plan-check fees, separate trade permits, the state Building Standards and seismic surcharges, resale inspection fees where a sale is involved, and any development impact fees. The permit number is issued after processing and is needed before fees can be paid online.

California layers two uniform state surcharges — the Building Standards Administration fee and the Strong Motion Instrumentation seismic fee — on top of the local charges, so they appear on permits everywhere. The building and plan-check fees themselves are local and change, and California law limits them to the reasonable cost of providing the service, so a figure from a neighbouring city is not reliable — ask Building Division for the schedule in force on your filing date.

Trade permits and who may pull them

Trade permits are separate from the building permit and, on projects that require one, generally cannot be issued until the building permit is in place. Each trade follows its own part of Title 24 — the California Electrical, Plumbing and Mechanical Codes — and is tied to a contractor holding the matching CSLB specialty classification, the same license statewide.

• Electrical work follows the California Electrical Code and a C-10 electrical contractor.
• Plumbing work follows the California Plumbing Code and a C-36 plumbing contractor.
• Mechanical work follows the California Mechanical and Energy codes and a C-20 HVAC contractor.

How to apply for a Davis building permit

Review, corrections and what actually causes delay

In California, the first cause of delay is uncertainty over jurisdiction — filing with the county when a city should have it, or missing a local amendment on top of Title 24. After that come Title 24 energy and CALGreen documentation, a CSLB classification that does not match the scope, and, in fire or coastal areas, defensible-space or coastal-zone requirements that were not addressed up front. Build the plan-check time into the schedule and confirm the checklist with Building Division before filing.

Inspections in Davis

Where a permit is required, standard checkpoints include footing and foundation, framing, rough-in electrical, plumbing and mechanical, insulation and Title 24 energy, CALGreen measures, fire systems on commercial work, and final, with a certificate of occupancy before use. Inspections are scheduled through the division once the permit is issued, with resale inspections booked at the time the application is paid.

California inspections are keyed to the code editions in force when the permit issued, so the approved plans and any energy and green-building documentation need to be on site for the inspector to check against. Confirm the notice Building Division needs and schedule around its inspection windows.

Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, product listings, Title 24 energy documentation and your correction responses available on site.

Davis permit search and official resources

Permit records in California sit with the local authority that issued them. Where the City of Davis Building Division is the authority for the City of Davis limits, it holds the building permit, the inspection history and the certificate of occupancy. If you are buying, refinancing or renovating, confirm that past work was permitted rather than assuming it was — and confirm the code edition that was in force.

How long does review take?

Applications are reviewed in the order received, with typical processing of five to ten business days after submission.

Can an owner pull the permit?

Yes. Property owners may apply for permits using the owner-builder form alongside the correct residential or commercial permit type.
