Fontana — Historic Preservation
Historic Preservation under the Fontana local zoning and planning code, with the controlling citations.
Last reviewed: July 2, 2026
Overview
Fontana's Zoning and Development Code does not create a single, dedicated historic-preservation chapter. Instead, historic-resource rules are woven into specific permit types and review pathways: accessory dwelling units (ADUs) (§ 30‑467), two‑unit / urban lot split rules (§ 30‑434.1), design review and sign rules (design review and Route 66 signage), and environmental/plan review submittal requirements (archaeological/historic reports). Where the Code expects a formal “certificate of appropriateness” it points to the Municipal Code Chapter that handles landmarks rather than reproducing a full landmark designation procedure in Chapter 30 (§ 30‑15) .
This page summarizes only what Fontana’s Zoning and Development Code (Chapter 30) says about historic resources, and cites the controlling code sections. Verify parcel‑specific status with the City (see Risks & Ambiguities).
How the Code treats historic resources (high level)
- ADU protections: an ADU that is on or within 600 feet of property listed in the California Register of Historic Resources must be located so it is not visible from any public right‑of‑way (§ 30‑467) . See the ADU rules for the full set of objective ADU design, parking and review standards (§ 30‑467) . Link: ADUs (/us/california/fontana/adu)
- Project‑level historic/archaeological review: many discretionary and some ministerial project applications require a site‑specific archaeological/historic/paleontological report as part of environmental/biotic resources submittals (§ 30‑633(c)(6)) .
- Two‑unit / urban lot split exclusions: the ministerial two‑unit project rules explicitly exclude lots that are historic or within a state historic resources inventory or are designated as a City/county landmark — the lot must be “not historic” to qualify (§ 30‑434.1(d)(4)) .
- Design review and sign context: design review finds and sign policies carry historical/contextual elements (e.g., Route 66 themed sign treatments and a downtown creative sign program) and require design review sign process where applicable (§ 30‑118—30‑124, § 30‑728 for Route 66 treatments) . Link: design review (/us/california/fontana/design-review)
- Certificate of appropriateness / landmark work: Chapter 30 references the ability to grant a certificate of appropriateness and points to Chapter 5 of the Municipal Code for the landmark/appropriateness procedures (§ 30‑15 lists the certificate of appropriateness reference) .
- Historic structures and building‑code variances: Fontana applies standard state rules for historic buildings (California Historical Building Code / Title 24) when evaluating building/variance issues for qualified historic structures (state code appendices referenced in local practice). Link: California Building Standards Code (/us/california/building-codes) .

District-by-district breakdown (relevant districts in historic context)
Note: the Code uses several zoning district names. Below I pull the Fontana district titles and the local code citations that set the standards that most affect historic resources review (setbacks, densities, and where project review/archaeological reports are applied).
R-1 (Single‑Family / Neighborhood)
- Purpose: preserve and exemplify standard single‑family neighborhood character; found in the Form‑Based and zoning tables for neighborhood district (§ 30‑364) .
- Typical permitted uses: single‑family detached dwellings; accessory structures; ADUs where permitted (ADU rules in § 30‑467) .
- Key dimensional standards: front/side/rear setbacks and story limits are those listed in Table No. (Neighborhood district tables) and summarized in § 30‑364; design/appearance controls are enforced through design review (§ 30‑118—30‑124) .
- Where it applies: citywide neighborhoods; projects within these zones may trigger archaeological/historic report requirements when environmental review requires a biotic resources management plan (§ 30‑633) .
R-2 / R-3 (Medium / High Density Residential)
- Purpose & uses: allow medium/high density multi‑family forms and related services; ADUs and accessory uses as governed by § 30‑467 and the multi‑family tables (§ 30‑444—30‑448) .
- Dimensional standards: building separation, setbacks, private/open‑space metrics appear in Table No. 30‑444 and related sections (§ 30‑444, § 30‑447) .
- Historic implications: conversions, large remodels and multi‑family ADU conversions must follow archaeological/historic reporting when required and ADU historical protections (§ 30‑633, § 30‑467) .
R-4 / R-5 (Multiple‑family Medium/High; Transit‑oriented overlay references)
- Purpose: supports higher density near transit and mixed‑use corridors; development standards and design guidelines are given in §§ 30‑445—30‑447 and cross‑references (R‑4 overlay also appears) .
- Uses & standards: ADUs/Duplex rules interact with these districts; design review and architectural compatibility requirements apply to protect character (§ 30‑445—30‑447, § 30‑118—30‑124) .
- Where it applies: near transit corridors and the R‑4 overlay map (see § 30‑445) .
C‑1 / C‑2 / RMU (Commercial / Regional Mixed Use)
- Purpose: commercial and mixed‑use activity centers; standards for signage, façades and Route 66 treatments live across the sign articles and the RMU tables (§ 30‑494.A, design rules across Article VI) .
- Historic implications: Foothill Boulevard / Route 66 character requirements are called out in sign/design sections (Route 66 themed signs requirement in design review entitlements) — see § 30‑728 and sign article for downtown/Route 66 character treatments .
Overlay Districts (e.g., Entertainment Center, Hillside, Auto Center)
- Purpose: overlay districts add special design rules that can interact with historic character (e.g., West End / Route 66, Entertainment Center Overlay § 30‑663; Auto Center overlays include plan review and design requirements) .
- Historic implications: where an overlay imposes design review it can require Route 66 / historic‑style sign or façade treatments as a condition of approval (§ 30‑663, § 30‑728) . Link: overlays (/us/california/fontana/overlay-districts)

Quick reference table — decision‑relevant historic items
| Rule / policy | What it controls | Code reference |
|---|---|---|
| ADU visibility near listed resources | ADU on/within 600 ft of California Register property must not be visible from any public right‑of‑way | § 30‑467(g)(7) |
| Two‑unit / urban lot split exclusion | Lots that are historic, on state inventory, or designated as City/county landmark are excluded from ministerial two‑unit projects | § 30‑434.1(d)(4) |
| Archaeological/historic reports | Projects requiring biotic resources/CEQA initial study must include a site‑specific archaeological/historic/paleontological report | § 30‑633(c)(6) |
| Route 66 / downtown sign character | New signage and design review for properties on historic Route 66 corridor must incorporate Route 66 themed treatments | § 30‑728 (design/sign rules) |
| Certificate of appropriateness referral | Landmark‑work approvals (certificate of appropriateness) are referenced from the project types list and handled per Chapter 5 of Municipal Code | § 30‑15 (y) |
| Design review authority & findings | Design review required for projects as specified; findings include compatibility and aesthetic quality | § 30‑118—30‑124 |
Checklist
- Confirm whether the property is listed on the California Register or state inventory (if yes, many ministerial pathways are precluded). Verify with the jurisdiction and State Office of Historic Preservation.
- For ADUs: ensure ADU location and elevation satisfy § 30‑467(g)(7) (not visible from public ROW if within 600 ft) .
- If the project is discretionary or triggers environmental review, include an archaeological/historic/paleontological report per § 30‑633(c)(6) .
- If pursuing a two‑unit / urban lot split, confirm the lot is not historic and meets the eligibility criteria in § 30‑434.1 (ministerial approval otherwise) .
- Expect design review if in an overlay or downtown/Route 66 corridor; prepare design elevations and sign plans consistent with § 30‑118—30‑124 and § 30‑728 .
- If the work affects an officially designated landmark (or you need a certificate of appropriateness), check Chapter 5 (Municipal Code) and the City’s Certificate of Appropriateness process referenced from § 30‑15(y) .
- Coordinate parking, setbacks and development‑standards compliance; historical constraints do not replace required code conformance (see parking, setbacks/development standards) . Link: development standards (/us/california/fontana/development-standards)
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| No single “Historic Preservation” chapter in Chapter 30 | Historic policies are scattered; you may miss a relevant rule if you only read one article | Verify parcel status and all applicable permit triggers with Planning staff; confirm whether landmark rules live in Chapter 5 (see § 30‑15(y)) |
| ADU “not visible” rule (600 ft) | Strict objective rule — can block ADU visibility even where ADU otherwise complies | Measure visibility from public right‑of‑way and include elevations in application; cite § 30‑467(g)(7) |
| Archaeological report triggers | CEQA/biotic plan submittal language requires archaeological/historic reports for many projects | Confirm whether your project “triggers” biotic/CEQA review; cite § 30‑633(c)(6) and verify with environmental planner |
| “Not historic” requirement for ministerial approvals | If property is on state inventory or locally designated, ministerial pathways (two‑unit projects, urban lot splits) may be ineligible | Check State Historic Resources Inventory and local records; see § 30‑434.1(d)(4) |
| Where to get landmark rules | § 30‑15 references certificates and Chapter 5 but the Code doesn't print the procedures inline | Ask the City for Chapter 5 (Municipal Code) landmark procedures and for any local historic surveys; cite § 30‑15(y) |
| Route 66 / Downtown character rules | Special sign and façade treatments can be required in design review for historic corridors | If on Foothill/Route 66 frontage expect Route 66 sign treatments under sign/design rules (§ 30‑728) |
Plain‑English Summary
Fontana does not have a single “historic preservation” chapter; instead the Zoning and Development Code protects historic resources by (1) carving out historic‑sensitive rules in specific approvals — for example ADUs (§ 30‑467) and two‑unit/urban lot splits (§ 30‑434.1) — and (2) requiring archaeological/historic reports for many projects (§ 30‑633). If your property is listed as historic (state or local), ministerial pathways may be blocked and you should coordinate with Planning and check Chapter 5 (certificate of appropriateness) before you apply .

Frequently asked questions
Do properties in a historic district get treated differently for ADUs in Fontana?
Yes. An ADU that is on or within 600 feet of property listed in the California Register of Historic Resources must be located so it is not visible from any public right‑of‑way; that requirement is in the ADU rules (§ 30‑467(g)(7)) .
What does Fontana require to prove whether a site is historic or in a historic district?
The Code treats a lot as ineligible for some ministerial pathways if it is “a historic property or within a historic district that is included on the State Historic Resources Inventory” or “designated by ordinance as a City or county landmark” (§ 30‑434.1(d)(4)). The Code does not itself publish the local landmark list; verify status with the City and the State Historic Resources Inventory database .
Will I need an archaeological report for a commercial or residential project?
If the project’s entitlement submittal or CEQA/biotic resources review requires it, the Code requires a site‑specific archaeological/historic/paleontological report to analyze and mitigate adverse impacts (§ 30‑633(c)(6)) .
Is there a “historic preservation overlay” or a local landmark procedure in Chapter 30?
No standalone historic overlay or complete landmark‑designation procedure appears in Chapter 30. The Code does reference a certificate of appropriateness for landmarks and points to Chapter 5 of the Municipal Code for that procedure (§ 30‑15(y)) — so look to Chapter 5 and ask Planning for the City’s landmark procedures and lists .
Do I need design review for façades or signs on Route 66 / Foothill Boulevard?
Yes. The sign/design rules include Route 66 character treatments and require design review or design‑sign entitlements in applicable locations; Route 66‑themed signage is explicitly called out as a character treatment to be incorporated during design review (§ 30‑728 and related design review provisions) .
Can I use the ministerial two‑unit project/urban lot split on a historic lot?
No. The two‑unit/urban lot split approval expressly disqualifies lots that are historic, included on the State Historic Resources Inventory, or designated as local landmarks (§ 30‑434.1(d)(4)) .
Where does landmark work (demolition or major alteration of a landmark) get decided?
Chapter 30 references a certificate of appropriateness for landmark work in its list of project types and directs users to Chapter 5 of the Municipal Code for those procedures (§ 30‑15(y)). For the full local process and the local landmark list, consult Chapter 5 and Planning staff .
If my project is in an overlay district, will historic/character standards be stricter?
Overlay districts (R‑4 overlay, Entertainment Center, Auto Center, etc.) include additional design and plan review requirements; if those overlays cover a Route 66 or downtown area, extra sign and façade character standards can apply (§ 30‑663, § 30‑445, § 30‑728) .
What should I submit with a development application if I think there are historic resources on site?
Include a professional archaeological/historic/paleontological report as required by the biotic resources/CEQA submittal rules (§ 30‑633(c)(6)) and prepare elevations that show whether ADUs would be visible from public ROW if you are within 600 feet of a listed resource (§ 30‑467(g)(7)) .
How do I appeal a design review or other decision that affects a historic property?
Design review decisions are appealed per the design review article (appeals to the City Council/Planning Commission per Division 4 / Article II); see the design review hearing and appeals process (§ 30‑118—30‑124) .
