Davis, California Building Permit Guide

Davis is a Yolo County city of about 66,000 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?

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); 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 California Wildland-Urban Interface Code (Title 24, Part 7, in force since 1 January 2026) and Cal Fire defensible-space requirements (Public Resources Code 4291) 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.

California builds on one statewide code, Title 24, whose 2025 edition took effect on 1 January 2026; the editions in effect when the application is submitted apply, and cities and counties may adopt local amendments only with findings filed with the state (new residential amendments are largely frozen until June 2031).

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 20 to 35 business days from submittal. 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.

In 2025, building permits issued in Davis authorized 68 new privately owned housing units, all of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

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: the seller files a resale inspection application, the city inspects and issues a report of violations, and corrective work with any required permits is completed before the resale certificate is issued — or by the buyer within 90 days of the sale. Owner-builders apply directly using the owner-builder form.

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 20 to 35 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.

Contractors are licensed statewide by the Contractors State License Board (Classes A, B, B-2 and C) for work of $1,000 or more or any permitted work; a city may also require a business licence or tax registration. Contractor licensing in California

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 (Health and Safety Code 18931.6; Public Resources Code 2705). 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

Each trade follows its part of Title 24 and is done by a contractor with the matching CSLB licence (C-10 electrical, C-36 plumbing, C-20 HVAC), a Class B contractor where allowed, or an owner-builder. Trade licences in California

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.

A building permit carries a validity period and can expire if work does not start or stalls between inspections; confirm the expiry with Davis on phased or delayed work. Permit validity in California

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 made against the code editions in effect when the permit application was submitted (Health and Safety Code 18938.5), 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.

Frequently asked questions

Who issues building permits in the City of Davis?

The Building Division within Community Development and Sustainability at the city offices on Russell Boulevard; unincorporated Yolo County and neighbouring cities are separate authorities.

What is the resale programme?

Before a house, duplex or triplex is sold, the owner applies for a city resale inspection. The city issues a report of violations, which the buyer must receive and sign before the sale; a resale certificate is issued once the violations are corrected. Apartment buildings of four or more units, hotels and motels file a self-certification form instead.

How long is a resale certificate valid?

A certificate is valid 18 months from validation, and a report is valid until a certificate issues or 18 months after the inspection. Either expires at once if the property is altered without a permit where one was required.

What happens if the seller does not complete the report items?

The sale can still close once the buyer has signed for the report, but the buyer must then correct the listed violations within 90 days of the sale. An unused report expires 18 months after the inspection, and a new inspection is then needed.

How long does review take?

Applications are reviewed in the order received, with typical processing of 20 to 35 business days from submittal.

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.
