Site Plan Requirements in Fresno, CA (Permit Guide)

Frequently Asked Questions

Do I need a permit to build a shed in Fresno, CA?

In Fresno, any detached accessory structure larger than 120 square feet requires a building permit. Sheds at or below that threshold may still need a zoning clearance to confirm they meet setback and lot coverage requirements for your specific zoning district. Even for smaller sheds, you should verify compliance with the Fresno Municipal Code before construction. When you apply for a permit, you will need to submit a site plan showing the shed's proposed location, its distance from all property lines, and its relationship to existing structures on the lot. Placing a shed too close to a property line or in a required setback area is one of the most common reasons permit applications are returned by Fresno's Development and Resource Management Department.

How long does it take to get a building permit approved in Fresno?

Permit approval timelines in Fresno vary based on project complexity. Simple over-the-counter permits for minor work -- such as water heater replacements or small electrical upgrades -- can sometimes be approved the same day or within a few business days. Standard residential projects like room additions, patio covers, and swimming pools typically go through a plan review process that takes 3 to 6 weeks for the first round of comments. ADUs reviewed under California's streamlined ministerial process must receive a determination within 60 calendar days of a complete application submittal. Projects that require Planning Division review, variance approvals, or historic district clearance will take longer. Submitting a complete, accurate application with a proper site plan from the start is the most effective way to avoid delays.

What does Fresno require on a residential site plan?

Fresno's Development and Resource Management Department (DARM) expects a residential site plan to include several key elements. You need to show the lot boundaries with accurate dimensions, a north arrow, a written scale (such as 1 inch equals 20 feet), and the addresses or assessor parcel number. The plan must depict all existing structures on the property as well as the proposed new construction, clearly labeled. Setback distances from all property lines to both existing and proposed structures must be called out. Utility easements, driveways, and access points should also be shown. For projects near flood zones, base flood elevation data may be required. Missing any of these elements is a leading cause of plan check corrections and application returns at DARM.

Can I draw my own site plan in Fresno, or do I need a licensed surveyor or architect?

For most standard residential permits in Fresno -- sheds, patio covers, pools, fences, and many ADUs -- you are not required to hire a licensed surveyor or architect to prepare the site plan. A homeowner-drawn site plan is acceptable as long as it is accurate, drawn to scale, and includes all elements required by DARM. However, the plan must reflect true property dimensions, so you should work from your recorded parcel map or a prior survey. For larger projects such as room additions or new construction, California law may require that structural drawings be stamped by a licensed engineer or architect, even if the site plan itself does not require a professional seal. Using an online tool like Site Plan Creator can help you produce a clean, professional-looking plan that meets Fresno's submission standards.

What are the typical setback requirements in Fresno for a single-family home?

Setback requirements in Fresno depend on your property's specific zoning designation, but typical single-family residential (RS) zones require a front yard setback of 15 to 25 feet, an interior side yard setback of 5 feet, a street-side setback of 10 feet on corner lots, and a rear yard setback of 15 to 20 feet for primary structures. Accessory structures and ADUs often benefit from reduced setbacks -- sometimes as little as 4 feet from side and rear property lines -- under California's ADU streamlining laws. Planned development zones, overlay districts, and historic areas may impose different standards. Always verify your parcel's exact requirements through the Fresno Municipal Code or by contacting DARM before finalizing your site plan, since building within a required setback without a variance can result in costly corrections or demolition orders.

How much does a building permit cost in Fresno, CA?

Fresno building permit fees are calculated based on the estimated construction valuation of your project. A plan check fee is collected at the time of application, and the balance of the building permit fee is due when the permit is issued. As a rough guide, a small patio cover or shed permit may cost a few hundred dollars in total fees, while a room addition or ADU permit can range from $1,000 to $3,000 or more depending on project value. Additional fees may apply for electrical, mechanical, and plumbing sub-permits, as well as for planning or zoning review. DARM publishes a current fee schedule on its website. Note that if your application is incomplete and requires multiple rounds of plan check review, each resubmittal may incur additional fees, making a complete first submission especially important.

Where do I submit a site plan and permit application in Fresno?

Fresno accepts permit applications through two main channels. The preferred method for most project types is the city's online permitting portal, eTRAKiT, accessible through the DARM website at fresno.gov/darm. Through eTRAKiT, you can submit your application, upload your site plan and supporting drawings as PDFs, pay fees electronically, and track your plan review status without visiting City Hall. If you prefer in-person assistance or have a complex project, you can visit the DARM permit counter at 2600 Fresno Street, Fresno, CA 93721. Counter hours vary, so check the DARM website for current availability. Some applicants find it helpful to schedule a pre-application meeting with a planner before submitting, particularly for ADUs or projects in zoning overlay areas.

What happens if I build without a permit in Fresno?

Building without a required permit in Fresno can lead to serious consequences. If the city discovers unpermitted work -- through a neighbor complaint, a routine inspection, or a real estate transaction -- DARM can issue a stop-work order requiring all construction to halt immediately. You may then be required to obtain a retroactive permit, which often involves more extensive inspections and documentation than a standard permit would require. In some cases, unpermitted structures must be partially demolished so inspectors can verify compliance with code requirements. Fresno may also assess penalty fees on top of standard permit fees for work done without authorization. Unpermitted additions can complicate home sales, affect homeowner's insurance coverage, and create liability issues. It is always less expensive and less stressful to obtain the proper permit before construction begins.

What are the ADU rules in Fresno, CA in 2026?

Fresno follows California's state ADU laws, which have made it significantly easier to build accessory dwelling units on single-family and multifamily lots. In 2026, Fresno allows ADUs up to 850 square feet (or larger in some configurations) by right on single-family parcels, with side and rear setbacks reduced to 4 feet. Junior ADUs (JADUs) up to 500 square feet can be created within the existing footprint of a primary residence. Owner-occupancy requirements were suspended under state law through at least 2026. DARM must act on a complete ADU permit application within 60 days. A site plan showing the ADU's location, setbacks, parking (if required), and utility connections is required with every application. Garage conversions to ADUs are popular in Fresno and generally do not require replacement parking under current state law.

Is my Fresno property in a FEMA flood zone, and does that affect my permit?

Parts of Fresno -- particularly areas near the San Joaquin River, Dry Creek, and other waterways -- fall within FEMA-designated Special Flood Hazard Areas (SFHAs), commonly referred to as the 100-year floodplain. You can check your property's flood zone status using the FEMA Flood Map Service Center at msc.fema.gov. If your property is in a SFHA, your building permit application must address flood zone compliance. This typically means your site plan must include base flood elevation data, and any new or substantially improved structure may need to be elevated above the base flood elevation. Fresno participates in the National Flood Insurance Program (NFIP), and DARM's floodplain administrator can answer specific questions about how flood zone designation affects your project's permit requirements and site plan content.

How to Create a Site Plan in Fresno

1. Confirm Your Permit Requirements: Before drawing anything, determine whether your specific project requires a building permit in Fresno. Review the Fresno Municipal Code or contact DARM at 2600 Fresno Street or through the city's website at fresno.gov/darm. Confirm your property's zoning designation, any overlay districts (historic, flood zone), and the specific setback and development standards that apply. This step prevents wasted effort on a site plan that does not match your project's actual requirements.
2. Gather Your Property Documents: Collect your recorded parcel map, property deed, and any prior survey documents. These give you accurate lot dimensions, easement locations, and boundary information that must appear on your site plan. You can obtain parcel maps from the Fresno County Assessor's Office or through the county's online GIS portal. Accurate property data is the foundation of a compliant site plan -- incorrect dimensions are a leading cause of plan check corrections at DARM.
3. Draw Your Site Plan to Scale: Using your property documents, create a scaled site plan that shows lot boundaries with dimensions, a north arrow, all existing structures, the proposed new construction with labeled setback distances, driveways, utility easements, and any trees or features relevant to the project. A common scale for residential lots is 1 inch equals 20 feet. Site Plan Creator's online tool lets you produce a clean, professional, to-scale drawing that meets Fresno's submission standards without requiring CAD software or drafting experience.
4. Submit Your Application Through eTRAKiT: Log in to Fresno's eTRAKiT permitting portal through the DARM website and create a new permit application. Upload your site plan and all supporting documents -- architectural drawings, structural calculations, Title 24 energy compliance forms -- as PDF files. Pay the plan check fee at the time of submission. If you prefer in-person submission, bring printed copies to the DARM permit counter at 2600 Fresno Street during counter hours. Keep a copy of your confirmation number and all submitted documents for your records.
5. Respond to Plan Check Corrections: After DARM's plan reviewer evaluates your application, you will receive either an approval or a correction notice listing deficiencies. Review each correction carefully and update your site plan and drawings to address every item. Resubmit through eTRAKiT or at the permit counter. Responding quickly and completely to correction notices is the most effective way to minimize your total permit timeline. Multiple rounds of corrections are common for larger projects, so build this time into your construction schedule.
6. Obtain Your Permit and Schedule Inspections: Once DARM approves your application, pay the remaining permit fee balance and download or pick up your issued permit. Post the permit visibly on the job site before any construction begins -- California law requires this. As work progresses, schedule required inspections through eTRAKiT or by calling DARM's inspection line. Common inspection milestones include foundation, framing, rough electrical and plumbing, and final inspection. A passed final inspection closes out your permit and confirms the work is code-compliant.
