Dinuba — Development Standards
Development Standards under the Dinuba local zoning and planning code, with the controlling citations.
Last reviewed: July 3, 2026
Overview
This page explains what Dinuba's zoning ordinance actually requires for development standards — setbacks, heights, coverage, density, and when modifications are permitted — as found in the city's Title 17 (Zoning). It focuses on the rules in the municipal ordinance (not the California Building Standards Code) and highlights where the code gives district-by-district numbers, where the code allows administrative flexibility, and where the municipal code defers to other chapters (for example on parking and signage). For state ADU-specific constraints, see the California ADU law; local rules must still be read against state limits.
District-by-district development standards
Below are the city code provisions you will actually use when sizing a project in Dinuba. Each district subsection lists the ordinance purpose, typical dimensional limits pulled from the code, typical permitted-use direction (when the ordinance text is explicit), and where the district commonly applies.
Notes on links: the first natural mention of related topics is hyperlinked to the Dinuba menu pages for quick cross-reference (for example, design review is linked where first mentioned).
R / R residential districts (general "R district")
- Purpose and context: The R district is intended to protect single‑family residential character and set standards for height, yards and landscaping.
- Typical permitted uses: The municipal code treats standard residential uses as permitted in the R district; a full permitted-use table is maintained within the R-district chapter (not reproduced verbatim here). Verify parcel-specific permitted uses with the zoning map. Not found in retrieved materials for a full use list; verify with the jurisdiction.
- Key dimensional standards:
- Maximum main building height: 2 stories / 25 ft (unless modified under the development-modification rules). § 17.20.100.
- Accessory structure placement and minimum separations are governed by the accessory standards in Chapter 17.71 (see accessory‑structure rules and minimum side/rear distances).
- Front-yard landscaping is required in the required front yard within six months of occupancy. § 17.20.130.
- Where it applies: Citywide residential neighborhoods designated "R" on the zone map. Verify with the official zone map.
RM-1.5 / RM-2 / RM-3 multifamily residential districts
- Purpose and context: The RM districts are for multifamily development at increasing densities: RM-1.5 (higher density), RM-2, and RM-3 (medium/medium‑high). The RM chapters provide explicit coverage, setback and height rules. § 17.24.010.
- Typical permitted uses: Multifamily dwellings and related residential support uses (see RM permitted‑use list in the RM chapter). Not all permitted‑use text is included in retrieved snippets; verify for parcel specifics.
- Key dimensional standards:
- Maximum site coverage (roofed structures): RM‑3 = 50% ; RM‑2 = 55% ; RM‑1.5 = 60%. § 17.24.080.
- Front setback (minimum average): 20 ft, but not less than 15 ft (garages/carports still must be set back 20 ft). § 17.24.090(A).
- Rear setback: minimum 15 ft; add 10 ft for each story above one story; additional increases when abutting an R district. § 17.24.090(B).
- Side setback: minimum 5 ft (special rules for corner and reverse corner lots). § 17.24.090(C).
- Distance between structures and unit-orientation rules are provided in the RM chapter; consult § 17.24.100–110.
- Where it applies: Multifamily areas identified as RM on the zoning map.
C-2 — General Commercial (Downtown / commercial core)
- Purpose and context: C-2 is the city's general commercial district and includes the downtown mixed‑use area where specific yard and frontage rules apply. § 17.42.
- Typical permitted uses: Retail, offices, services; the downtown overlay allows mixed land use with residential above commercial via conditional use. See the Downtown Residential Overlay (below).
- Key dimensional standards:
- Maximum building height: 75 ft in standard C-2. § 17.42.090.
- Minimum front yard (when abutting a residential district): 15 ft, and at least 50% of that yard must be landscaped. § 17.42.100.
- No side or rear yard requirement generally, except where the site abuts a residential district — then special landscaped yards of 10 ft or more apply; side setbacks up to 10–15 ft in some abutting situations are required. §§ 17.42.110–120.
- Where it applies: Downtown and other commercial corridors mapped C‑2.
Downtown Residential Overlay (superimposed on C‑2)
- Purpose and context: The Downtown Residential Overlay encourages mixed residential over commercial in the downtown core; it is superimposed on C‑2 areas. § 17.61.010–030.
- Key dimensional standards (minimums for mixed-use projects, reviewed by the planning commission):
- Minimum lot size: 3,750 sq ft. § 17.61.050(A).
- Minimum lot width: 25 ft; depth: 150 ft. § 17.61.050(B).
- Maximum building height: 40 ft / 3 stories. § 17.61.050(C).
- Maximum residential density in mixed projects: 24 units/acre (1,875 sq ft per unit). § 17.61.050(D).
- Where it applies: C‑2 parcels within the downtown overlay map; mixed‑use requires conditional use permit. § 17.61.040.
BA — Boulevard Overlay District
- Purpose and context: The BA overlay adds frontage and yard rules on arterial and collector boulevard segments. § 17.63.010–020.
- Key standards:
- Under BA the depth/width of yards that abut a street are set on the zone map numerals that follow “(BA)”; yards shall be landscaped and may not exceed 30 ft in depth from the ultimate property line unless frontage roads or plan lines say otherwise. § 17.63.020(D).
- Where it applies: Parcels mapped with the BA overlay symbol on the official zone map.
PUD / Precise Plan / Other overlays
- Planned Unit Development (PUD overlay): permits flexibility in layout, but final design must show density, height, open space and parking; PUDs must satisfy findings in § 17.92.070. § 17.92.
- Precise Plan overlay: property within a precise plan must conform to both the precise plan and the underlying zone. § 17.62.050.
- These overlays change how standards apply; consult the overlay chapter that appears on the zone map. See the city's overlay districts page for context.
P / PO / M (public, professional office, manufacturing)
- The code treats P, PO, C, M districts differently for fencing, walls, and some setbacks; e.g., wall/fence waiver language and landscaping requirements appear in Chapter 17.93 and other district chapters. For communications towers in M-1 / M-2, the code applies underlying district height and lot requirements and a fall‑zone rule keyed to tower height. §§ 17.73.040(B–D).
Quick reference table — the most decision-relevant numeric standards
| District | Key numeric standards (typical) | Notes / Code Reference |
|---|---|---|
| R (R district) | Height: 25 ft / 2 stories; front‑yard landscaping required | § 17.20.100, § 17.20.130 |
| RM‑3 / RM‑2 / RM‑1.5 | Coverage: RM‑3 = 50% ; RM‑2 = 55% ; RM‑1.5 = 60%; Front setback 20 ft avg / min 15 ft; Side 5 ft; Rear 15 ft (+10 ft/story) | § 17.24.080–090 |
| C‑2 | Max height 75 ft; where adjacent to residential, front yard 15 ft & 50% landscaped; special side/rear when adjoining residential | § 17.42.090–120 |
| Downtown Overlay (on C‑2) | Max height 40 ft / 3 stories; max density 24 units/acre; min lot 3,750 sf | § 17.61.050 |
| BA overlay | Yard widths and frontage yards set on zone map numerals (may be up to 30 ft) | § 17.63.020 |
| Modifications/relief | Director/PC may allow reductions/increases up to 10% for setbacks, height, coverage under the modification process | § 17.93.040(A, D, F) |
Notes: Floor area ratio (FAR) is not stated in the retrieved materials for general districts — Not found in retrieved materials. For precise parking counts, see Chapter 17.64 (parking) and for landscaping requirements see Chapter 17.71; both are referenced across the code.
How modifications and PUDs change the numbers
- The city has a formal process to allow "modified standards" where a developer can request adjustments (setbacks, height, lot dimension reductions, etc.). The modification chapter explicitly lists the types of adjustments and treats the listed numbers as minimums and a baseline for allowances; the director or the discretionary permit process reviews these. § 17.93.030–040. Modification examples: setbacks and yard encroachments up to 10%; height increases up to 10%.
- Planned Unit Developments (PUD) allow more design flexibility but must meet required findings related to density, open space, parking and buffering. See § 17.92.060–070 for required findings and process.
Checklist — what an applicant must satisfy (site plan / building‑permit submittal)
- Confirm the zoning district and any overlay(s) on the parcel (e.g., BA, Downtown Overlay, PUD/Precise Plan). Verify map.
- Demonstrate conformance to the district's height, setback, and coverage rules (use the district tables above; see §§ 17.20, 17.24, 17.42 as applicable).
- Provide a site plan that shows parking and loading consistent with Chapter 17.64 (parking).
- Demonstrate required landscaping and screening per Chapter 17.71 and the overlay rules; include irrigation and plant plans (landscaping and screening).
- If the project seeks a modification, supply a written justification and show the proposed modified dimensions (processing per § 17.93.030). § 17.93.
- For downtown mixed‑use proposals, include unit mix, densities and compliance with the Downtown Overlay minimums in § 17.61.050.
- Check for any nonconforming use/structure issues that could constrain additions or rebuilding (Chapter 17.96).
- Expect site plan administrative review or planning‑commission review depending on the permit requested (Chapter 17.80).
- If proposing signage or communications towers, follow the sign and communications rules (see signage and § 17.73 for tower criteria).
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| FAR (floor‑area ratio) not specified | FAR controls building bulk; absence means you must rely on coverage and height limits only | Verify with planning staff whether FAR is used for this parcel or project. Not found in retrieved materials. |
| ADU local rules vs state ADU law | State ADU law limits local setback/size rules — local ADU rules can’t conflict with state minimums | Verify ADU setbacks/height allowed locally and cross‑check California ADU law. See California ADU law and local ADU chapter. |
| Modification allowances (10%) | Code allows up to 10% flexibilty in setbacks/height/coverage via the modifications process; overreliance without formal approval risks denial | If you plan to use the 10% flexibility, file the modification per § 17.93 and document findings. |
| Overlay map numerals (BA yards) | BA yard depths are indicated by numerals on the zone map — not all numerals are printed within the code text | Check the official zone map for the parcel’s BA numeric yard requirement. § 17.63.020. |
| Nonconforming status for lot / front yard averages | Front‑yard averages and nonconforming reductions can alter required setbacks in an entire block | For infill or small lots, confirm whether § 17.71.100 chain‑block averaging applies and whether the lot is nonconforming. |
Plain‑English summary
Dinuba's Title 17 sets concrete numeric rules for setbacks, heights and lot coverage in each zoning district (for example RM districts have explicit coverage limits and front/rear/side setbacks; C‑2 has a 75‑ft height cap and special yards where it borders residential). The code also offers a formal modification process that allows modest (typically up to 10%) relaxations when justified; overlays and PUD/precise plans further change how the base standards apply. Always check the official zone map and overlay numerals and run any proposed relaxations through the modification or discretionary permit process.

Frequently asked questions
What is the maximum building height in Dinuba's R district?
In the R district the municipal code caps most main buildings at two stories or 25 feet for main buildings, subject to modification only through the formal modification or permit processes (§ 17.20.100)
What are Dinuba’s setback requirements for RM (multifamily) zones?
RM districts require a front setback averaging 20 ft (but not less than 15 ft), a rear setback of 15 ft (plus 10 ft additional for each story above one), and side setbacks of 5 ft (with special larger street‑side setbacks for corner or reverse corner lots) (§ 17.24.090)
How much lot coverage is allowed in RM zones?
Maximum roofed structure coverage is RM‑3 = 50%, RM‑2 = 55%, and RM‑1.5 = 60% as measured by roofed horizontal floor area over lot area (§ 17.24.080)
Can the city modify setbacks or height limits for an infill project?
Yes — Dinuba’s modification process allows review of reduced setbacks, lot‑dimension reductions, and small increases in height (the code cites up to 10% allowances for some standards) through the director or discretionary permit process (§ 17.93.030–040)
Do downtown mixed‑use projects have separate standards?
Yes — the Downtown Residential Overlay (applied to C‑2 downtown parcels) sets its own minimum lot sizes (3,750 sf), lot width/depth (25 ft / 150 ft), a maximum height of 40 ft / 3 stories, and a maximum residential density of 24 units/acre for mixed‑use projects (§ 17.61.050)
Are there local FAR limits in Dinuba’s zoning chapters?
No explicit citywide FAR numbers were found in the retrieved ordinance text for the common zoning districts. The code uses coverage, height and setbacks as bulk controls instead. Verify with the planning department if a parcel‑specific FAR applies. Not found in retrieved materials.
Where are parking and landscaping requirements defined?
Parking counts and standards are in Chapter 17.64 (referenced throughout the zoning chapters); landscaping and screening standards are in Chapter 17.71. Both are applied as part of site plan review. See the parking chapter references in the zoning text and the landscaping chapter for front‑yard landscaping rules (§ 17.64, § 17.71)
If my lot is smaller than the minimum, can I still build?
The code allows certain flexibility for substandard lots through the modification/variance and PUD processes and recognizes "legal substandard lots" in cases of eminent domain; however, lot‑by‑lot treatment varies and reconstruction of nonconforming structures has limits (see Chapter 17.96 on nonconforming uses and § 17.93 for modifications). Verify with the planning department for parcel‑specific guidance.
Do local ADU rules limit setbacks and lot coverage?
Local ADU rules must be read against state ADU law. State rules prohibit certain local restrictions that would prevent construction of an 800‑sf ADU with 4‑ft side and rear setbacks. Check both the city's ADU chapter and state ADU law; state guidance is summarized in the ADU handbook. See the city's ADU page and California ADU law for details.
