Do I need a permit for a small shed in Davis?

It depends on size and location. Detached sheds under 120 square feet with a single-layer roof and no electrical/plumbing are often exempt in Davis if they're not within setback areas. Sheds over 120 square feet, sheds in front yards or setback areas, or sheds with electrical/plumbing always need a permit. Call the Building Department or check the online portal to confirm before building.

How long does a Davis building permit take?

Over-the-counter permits (fences, simple decks, water-heater swaps) are often issued the same day or within a few days. Plan-review projects (additions, remodels, ADUs, pools) typically take 3–6 weeks from filing to first review, depending on completeness and reviewer workload. Appeal periods and re-submittal cycles can extend the process. Filing electronically through the online portal can be faster than in-person, but a quick phone call before you draw plans is almost always the smartest move.

Can I pull a permit myself as an owner-builder in Davis?

Yes. California law allows owner-builders to pull residential permits for their own properties. However, you must hire licensed contractors for electrical and plumbing work — Davis will not sign off on a permit if an unlicensed person performs those trades. You can do framing, finishing, HVAC equipment installation (often), and mechanical work yourself, but electricians and plumbers must be licensed and carry workers' comp.

What is Title 24 compliance and why does it slow down Davis permits?

Title 24 is California's energy code, part of the Building Code. Any alteration, addition, or new construction must meet Title 24 standards for insulation, windows, HVAC efficiency, and water heating. Davis permit reviewers scrutinize Title 24 compliance carefully. A simple addition needs thermal-envelope calculations and HVAC load analysis before it's approved. This is not unique to Davis — it's a state-wide rule — but Davis enforcement is consistent and thorough. Budget time and engineering fees for this step if you're planning an addition or remodel.

Do I need a permit to replace my roof in Davis?

Yes. Roof replacement is a permitted activity. If you're replacing like-for-like (same material, same slope, no changes to the structure or pitch), the permit is usually a low-cost, routine filing processed in a few days. If you're changing the pitch, adding skylights, or changing materials in a way that affects the load, structural review may be required. Talk to your roofer — they can advise on what the inspector will ask to see.

What happens if I skip the permit for a deck or shed?

Short term, you might get away with it. Long term, you create a liability problem. If the structure fails or causes injury, your homeowner's insurance will likely deny a claim because the work was unpermitted. If you sell the house, a home inspector or title company will often flag unpermitted structures, and you'll face a costly legalization process (re-inspection, retroactive code compliance, fees) or a demand to demolish. Davis is a conscientious community with active code enforcement — unpermitted work is often caught during routine inspections or when neighbors report it. The cost of a permit is always cheaper than the cost of remediation.

Are there online filing options in Davis?

Yes. The City of Davis offers an online permit portal for many routine projects (fences, solar, some decks, sheds). More complex projects (additions, remodels, ADUs) can often be submitted through the portal as well, with plan PDF uploads. Verify the current portal status and link on the City of Davis website — online services are frequently updated.

What is the permit fee structure in Davis?

Fees vary by project type and valuation. Fences, sheds, and simple decks have flat or low fees (typically $75–$300). Plan-review projects are usually calculated as a percentage of project valuation — often 1.5–2.5% for residential work, plus inspection fees. A $50,000 addition might carry a $750–$1,250 permit fee. Call the Building Department or use the online portal to get a quote for your specific project.

Building Permits in Davis, CA (2026)

Do I need a permit in Davis, CA?

Davis enforces the 2022 California Building Code (Title 24) with local amendments adopted through the Davis Municipal Code. The City of Davis Building Department handles all residential and commercial permits from a single intake. Davis is a college town with a strong sustainability focus — expect permit reviewers to scrutinize energy compliance, water efficiency, and setback rules more closely than in some California cities. Most single-family residential permits (decks, fences, solar, water heaters, HVAC replacements) are processed over-the-counter or by plan review within 2–4 weeks. Anything touching structure, electrical, plumbing, or mechanical almost always needs a permit. Owner-builders can pull permits themselves for most work, but California Business and Professions Code section 7044 requires licensed electricians and plumbers for those trades — no exceptions. The city's online portal exists and handles many routine filings, but phone calls to the Building Department often save time when you're unsure whether your project crosses the permit threshold.

What's specific to Davis permits

Davis sits in the inland valley (Yolo County) with mild winters and hot, dry summers — frost depth is not a significant factor for foundation design like it is in the Sierra foothills. That said, Title 24 energy code compliance is strict here. Any additions, alterations to existing homes, or new construction trigger mandatory Title 24 compliance, which means thermal envelope, insulation R-values, and HVAC efficiency get audited during plan review. A simple deck or shed might sail through; a bedroom addition or kitchen remodel will need a Title 24 energy analysis and likely an HVAC load calculation.

The city has strong tree-preservation rules. If your lot has a heritage oak or California bay laurel over 15 inches diameter, you'll need a tree-removal permit or a tree-protection plan during construction. This catches many homeowners by surprise during lot surveys for decks, pools, or grading. Get a certified arborist report if you're working near existing trees.

Davis is a bike-friendly city with specific bicycle parking and EV charging requirements for new construction and major remodels. If you're adding an ADU (accessory dwelling unit) or adding significant square footage, expect the plan reviewer to ask about bike parking and possibly EV charging infrastructure. These aren't prohibitive — just plan ahead.

The online permit portal is functional for many routine applications (fences, sheds, decks under certain thresholds, solar), but plan-review projects (additions, remodels, new homes) still benefit from an in-person or phone conversation before filing. The Building Department staff are helpful and can tell you in a 10-minute call whether your project will glide through or hit review complications.

Seasonal delays can occur mid-August through early September when staff levels drop during the UC Davis academic calendar changeover. Filing in late July or early September can mean a slightly faster turnaround than mid-August.

Most common Davis permit projects

These are the projects that bring homeowners to the Building Department most often. Each has its own fee structure, timeline, and local wrinkles.

Decks

Decks over 30 inches high require structural plans, footing inspections, and a permit. Davis typically processes these over-the-counter if plans are standard (under 500 square feet, simple joist layout). Setback rules vary by zoning; confirm your rear-yard setback before designing.

Fences

Fences over 6 feet (side/rear yard) or over 3.5 feet (front yard) require a permit. Masonry walls over 4 feet also need a permit. Corner-lot and setback rules are stricter; many Davis lots are subject to additional sight-triangle restrictions. Get the zoning map pulled before you order materials.

Roof replacement

Roof replacement is a permitted activity in Davis. If you're changing the roof pitch or adding skylights, structural review may be required. If you're reroofing like-for-like with the same material and slope, it's usually a simple, low-fee permit processed in days.

HVAC

HVAC system replacement requires a mechanical permit and Title 24 compliance documentation. Like-for-like replacement is usually straightforward; upsizing the tonnage or changing from one system type to another triggers a load calculation and plan review.

Solar panels

Residential rooftop solar requires a permit and Title 24 energy analysis. Davis has many solar installations and the process is streamlined — most over-the-counter with a plan check. Expect 2–3 weeks from filing to inspection. Interconnection with PG&E is separate from the city permit.

Accessory dwelling units (ADUs)

ADUs are allowed by state law (Government Code 66411.7 et seq.). Davis has local incentives and expedited review for qualifying ADUs. Standard plan review applies; expect 4–8 weeks depending on complexity. Local code requires bike parking and EV charging for some ADU types.
