Campbell — Historic Preservation
Historic Preservation under the Campbell local zoning and planning code, with the controlling citations.
Last reviewed: July 1, 2026
Overview
Campbell regulates historic preservation in Chapter 21.33 of the Zoning Code (Title 21) and by applying an H historic overlay/combining district (Chapter 21.14) to properties or areas designated as historic. The rules set out how properties become listed, who reviews work, and two permit “tiers” for exterior work (Tier 1 — routine alterations consistent with the Secretary of the Interior’s Standards; Tier 2 — relocations, demolitions, or work inconsistent with the Standards). See Campbell’s zoning & planning overview for how this chapter fits into local planning. § 21.33.010—.020; § 21.14.020.
Note: this page covers only the Campbell zoning/planning ordinance historic-preservation rules (Title 21). It does not substitute for building code (see California Building Standards Code) or permit/tenant law.

How the ordinance works (quick map)
- The historic-preservation rules sit in Chapter 21.33 (Historic Preservation). They apply to any property listed on the City’s Historic Resource Inventory (structures of merit, landmarks, and historic-district properties). § 21.33.020.
- When the City designates a landmark or historic district, the City Council adopts an ordinance that also combines the base zone with the H overlay. § 21.33.060.C.3; § 21.14.020.C.
- Review authorities are split among the Historic Preservation Board, the Planning Commission, and the City Council according to Table A in § 21.33.030 (e.g., designation goes to City Council after HPB/PC recommendation). § 21.33.030.
District-by-district breakdown (how historic rules interact with local districts)
The H overlay is a combining district that carries historic rules on top of whatever base zoning applies. The ordinance generally says the H overlay does not change allowed uses (uses remain those of the base district) but does make all development within the overlay subject to Chapter 21.33. Where possible below, I list the base-district standards that are most decision-relevant when an H overlay applies.
Important: the H overlay prefix is expressed on the map as a suffix to the base district (e.g., R-1-6-H, TO-MU-CB, GC-O). § 21.14.010.B; § 21.14.020.
R-1 (Single‑Family Residential; examples: R-1-6, R-1-8)
- Purpose: single-family neighborhood preservation and compatible infill. See residential standards in Article 2. § 21.08.050.
- Typical permitted uses: single-family homes, accessory structures, and accessory dwelling units (subject to ADU rules). The H overlay does not change allowed uses (the base-district uses remain). § 21.14.020.D.
- Key dimensional standards (general): Maximum FAR 0.45, Maximum lot coverage 40%, Front setback 20 ft, Side setbacks 5 ft, Rear 5 ft, Maximum height 35 ft (see Table 2‑4). These standards are applied to properties even when the H overlay is combined; the City may grant zoning exceptions for historic resources in limited circumstances (§ 21.33.150.B). § 21.08.050; § 21.33.150.B.
- Where it applies: older Campbell neighborhoods; note suffixes like R-1-6-H indicate the overlay. § 21.14.010.B.
LMDR / MDR / MHDR / HDR (Low‑Medium → High‑Density Residential)
- Purpose: multi‑family or mixed‑density housing permitted per Chapter 21.07 (MFDDS) and Article 2 form‑based exceptions. Historic resources are expressly excepted from MFDDS when listed on the Historic Resource Inventory—Chapter 21.07 excludes historic resources from those ministerial standards. § 21.07.020; § 21.07.040(c).
- Typical permitted uses: multi‑unit residential uses allowed by the underlying map symbol; historic overlay does not change uses. § 21.14.020.D.
- Key dimensional standards: many multi‑family zones are governed by the Multi‑Family Development and Design Standards (MFDDS) and may have FAR minimums/exceptions; note properties included on the Historic Resource Inventory may be treated differently (e.g., not subject to certain MFDDS provisions). § 21.07.020; Table 2‑10.
GC (General Commercial) and commercial mixed‑use districts (e.g., CB‑MU, TO‑MU)
- Purpose: commercial or mixed‑use development; downtown and corridor character rules apply in Central Business and Transit‑Oriented areas. See Downtown design standards and Central Business Mixed‑Use rules. § 21.11 (Downtown design), Table 2‑10.
- Typical permitted uses: commercial uses as listed in the Land Use Tables; properties on the Historic Resource Inventory may have additional restrictions for certain uses (e.g., bed & breakfasts limited to listed historic structures). Table 2‑11 notes some uses are restricted to historic-resource properties. § 21.10 and Table 2‑11.
- Key dimensional standards (commercial): Max FAR 1.0, Front setback GC 10 ft, Maximum height: GC 75 ft (Table 2‑7). When a property on the Historic Resource Inventory is involved, the City Council may grant exceptions to F.A.R. via a Zoning Exception per § 21.33.150.B. § 21.10.050; § 21.33.150.B.
(Use tables above as a quick reference — CHECK the exact base-zone map symbol on the City zoning map to confirm which base rules apply to any particular historic H parcel.) § 21.04.030.
Key decision rules & permits (one‑page table)
| What you’re doing | How Campbell treats it (short) | Code reference |
|---|---|---|
| Applying historic overlay to a landmark or district | Overlay added by ordinance when Council designates landmark/district; all development in overlay subject to Chapter 21.33. | Designation/ordinance: § 21.33.060.C.3; H overlay: § 21.14.020. |
| Exterior alterations that conform to Secretary of the Interior Standards | Tier 1 Historic Resource Alteration Permit; H.P. Board recommendation; decision body per Table A. | Tier 1 permit: § 21.33.080. Decision bodies: § 21.33.030 Table A. |
| Exterior alterations that do not conform / relocation / demolition | Tier 2 Historic Resource Alteration, Relocation, or Demolition Permit; CEQA review/fees; public hearings and stricter findings required. | Tier 2 permit: § 21.33.090. |
| Designation criteria (structure of merit / landmark / district) | Historic evaluation, DPR 523 forms, owner acceptance (owner must accept designation; district requires ≥60% owner acceptance). | Designation criteria & initiation: § 21.33.060. |
| Permitted uses in H overlay | Uses remain those of the base zoning district; overlay adds historic-review requirements. | H overlay allowed uses: § 21.14.020.D. |
Practical guidance / synthesis
- Start by checking whether the property is on the City’s Historic Resource Inventory or the Eligible Resource List. If it is listed as a Historic Resource, Chapter 21.33 applies; if it’s only on the Eligible Resource List, it is not regulated until City Council designation. § 21.33.020; § 21.33.050.E.
- For most exterior work on landmarks and historic‑district properties, expect a Tier 1 Historic Resource Alteration Permit and a Historic Preservation Board hearing; the project must meet findings tied to the Secretary of the Interior’s Standards. If the Director finds a proposed change would be a “significant alteration” or inconsistent with the Standards, the project upgrades to Tier 2 (more documentation, CEQA fees, and stricter findings). § 21.33.070—.090.
- The H overlay does not change what uses are allowed on a parcel (uses remain those of the base zone), but it does subject projects to the Chapter 21.33 review and can require additional submittals (architectural questionnaire, DPR 523, historic evaluation report, structural reports when needed). § 21.14.020.D; § 21.33.070.A.
- Historic properties may qualify for incentives (Mills Act tax-contract program, fee waivers, zoning exceptions) but these are discretionary and at Council’s prerogative. § 21.33.150.

Checklist (what an applicant must supply / satisfy for exterior work on a designated historic resource)
- Confirm whether the parcel is on the City Historic Resource Inventory or only the Eligible Resource list (Chapter 21.33). § 21.33.020.
- Pre‑application consultation with Community Development or Historic Preservation Board recommended (HPB may provide non‑technical advice). § 21.33.050.D.
- Completed application packet per § 21.33.070.A: clear Statement of Work, historic evaluation report / DPR 523 forms (as required), photos, and any structural/engineering reports requested by the Director. § 21.33.070.A.
- Determine whether proposed work is Tier 1 (conforms to Secretary Standards) or Tier 2 (does not conform / demolition / relocation). Tier 2 requires CEQA documentation and fees. § 21.33.080—.090.
- If applicable, prepare DPR 523 forms and an Historic Evaluation Report prepared by qualified historian/architect. § 21.33.060.A.1—2.
- Be prepared for public hearing(s): Historic Preservation Board, Planning Commission, and/or City Council depending on the action (see Table A). § 21.33.030 Table A.
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Whether a work is “ordinary maintenance” vs “material change” | Material changes trigger historic review; maintenance does not. Misclassification delays permits. Verify if the Director or HPB treats the change as material. (§ 21.33.040 definition) | Confirm with Community Development/HPB whether the specific change is “material” under § 21.33.040; request a written determination. |
| Owner consent for designation of a property/district | Designations require owner acceptance; districts require ≥60% owner acceptance. Without written owner acceptance, designation cannot proceed. (§ 21.33.060.A) | If pursuing a designation or facing nomination, confirm owner signature/date and whether district nominations hit the 60% threshold. |
| CEQA scope and fees for Tier 2 actions | Tier 2 (demolition/relocation/non‑conforming alteration) requires CEQA analysis/funding by applicant; this can add large time/cost. (§ 21.33.090.A) | Early consultation with Community Development to estimate CEQA scope. Budget for CEQA studies / city fees. |
| Extent of allowed zoning exceptions for historic resources | Zoning Exception can relax setbacks, parking, signage, etc., but is discretionary and must meet findings. This is not automatic relief. (§ 21.33.150.B) | If you need relief, prepare a Zoning Exception showing minimum departure and consistency with General Plan and design guidelines. |
| ADU design controls vs historic protections | State ADU law and local ADU standards interact with historic protections: ADUs are allowed on historic properties but local objective standards may be applied to avoid adverse impacts. | Confirm how local ADU standards apply to your historic property and whether objective standards for avoiding adverse impacts are being used. Verify with planning staff. (§ 21.23; state ADU law—see California ADU law). |
Plain‑English Summary
If your Campbell property is on the City’s Historic Resource Inventory, exterior changes are subject to Chapter 21.33 review: small changes that follow the Secretary of the Interior’s Standards are handled as Tier 1 with historical‑board input; demolitions, moves, or changes that harm character are Tier 2 and require CEQA and stronger findings. The H overlay does not change allowed uses but layers historic review on top of the base zone’s development standards (setbacks, FAR, parking). § 21.33.070—.090; § 21.14.020.

Frequently asked questions
What happens if my Campbell property is listed as an Eligible Resource but not yet designated?
If the property is only on the Eligible Resource List it is not yet regulated by Chapter 21.33; eligible listing is informational only. The property becomes regulated only after City Council designation as a structure of merit, landmark, or historic district. § 21.33.050.E; § 21.33.060.
What are the differences between a Tier 1 and a Tier 2 Historic Resource permit in Campbell?
Tier 1 (Historic Resource Alteration Permit) is for exterior work that conforms to the Secretary of the Interior’s Standards and is processed with HPB recommendation and the decision body named in Table A. Tier 2 covers work inconsistent with the Standards, relocations, or demolitions and requires CEQA documentation and stricter findings. § 21.33.080—.090.
Do historic designations change what I can use my property for?
No — when the City applies the H overlay the principal, accessory, and conditional uses remain those of the base zoning district; however all development becomes subject to Chapter 21.33 historic review. § 21.14.020.D; § 21.33.020.
Can the City require me to keep a landmark in good repair?
Yes. The ordinance defines a property owner’s “Duty to Keep in Good Repair” and owner agreement is required upon designation; the City may act to preserve a historic resource when reasonable and necessary. See the Duty to Keep in Good Repair definition and § 21.33.070 (interim measures). § 21.33.100 (definition referenced) and § 21.33.070.C.
Can I get zoning relief for a historic building that can’t meet modern setback/parking standards?
Yes — the City Council may grant an economic incentive or a Zoning Exception to relieve specific standards (setbacks, parking, sign area, permitted uses) for designated historic resources if the required findings are made. This is discretionary and requires demonstrating the exception is the minimum needed and consistent with the General Plan. § 21.33.150.B.
Are ADUs allowed on historic properties in Campbell?
Yes. ADUs are allowed in historic districts and on parcels with historic-designated primary residences, but the City may apply objective design and development standards that prevent adverse impacts to properties listed in the California Register of Historical Resources. Verify the specific local ADU standards for your parcel. Chapter 21.23; state ADU law.
Who decides whether my alteration “alters character‑defining features” and triggers HPB review?
The Community Development Director initially reviews building‑permit applications affecting historic resources. If the Director determines the work alters character‑defining features (or if the property is a landmark or district property), the application is forwarded to the Historic Preservation Board for review. § 21.33.070.B; Table A (decision authority).
What documentation will the City ask for when I submit an exterior‑alteration application on a historic resource?
Typical submittal items include a clear Statement of Work, photographs, DPR 523 forms when required, a Historic Evaluation Report prepared by a qualified professional, and any structural reports requested by the Director; see § 21.33.070.A for the full list.
If my project meets the Secretary of the Interior’s Standards, is it guaranteed approval?
No — work that conforms to the Standards will generally qualify for Tier 1 review and be processed accordingly, but the decision body still must make the required findings and may approve with modifications or deny. The HPB provides recommendations and may propose reasonable modifications. § 21.33.080.B—C.
Can the City force a sale, move, or demolition of a historic property?
The City may take interim preservation measures (consultation, acquisition by public/private body, relocation, salvage) it deems reasonable and necessary, but compelled sale/demolition is not the normal course; demolition or relocation decisions follow Tier 2 procedures with CEQA analysis and findings. § 21.33.070.C; § 21.33.090.
