Overview

Whittier’s historic preservation program sits in Title 18 of the Whittier Municipal Code (the historic resources chapters) and establishes (1) how individual historic landmarks and historic districts are nominated and designated, (2) when a certificate of appropriateness or waiver is required for work, and (3) special procedures for demolition, replacement and infill within designated districts. The rules apply citywide to resources that are at least 50 years old and use the Historic Resources Commission and City Council as the decision bodies. Relevant findings and review timelines are set out in the code (§ 18.84.*) .

Note: this page covers only what Whittier’s zoning/planning ordinance says about historic preservation (designation, review, waivers, demolition stays, Mills Act references and district rules). For underlying numeric development standards (setbacks, lot coverage, parking) see the city’s general Whittier Development Standards and Whittier Zoning pages; for building-code compliance use the California Building Standards Code.

How the ordinance is organized (quick orientation)

General historic resources & definitions and the Certificate of Appropriateness (COA) procedures are in Chapter 18.84 (multiple Articles) — e.g., applicability (§ 18.84.030), designation criteria (§ 18.84.050–060), COA rules (§ 18.84.150–210), demolition/replacement (§ 18.84.400–420), and the State Historic Building Code reference (§ 18.84.440) .
Individual local historic district chapters set district boundaries and district-specific COA procedures and guidelines: Earlham (Chapter 18.86), Hadley/Greenleaf (Chapter 18.87), Central Park (Chapter 18.88), College Hills (Chapter 18.89) — each contains purpose, boundaries, design guidance and special timelines/appeals for that district .

District-by-district breakdown

Earlham Historic District (Chapter 18.86)

Purpose: Protect and preserve the district’s historic integrity (the College Villa tract / Whittier College neighborhood, period of significance 1903–1940) (§ 18.86.010–020) .
Typical permitted uses: The chapter describes the area as a residential neighborhood; permitted uses are governed by the underlying zone but changes that alter historic resources require COA review per Chapter 18.84. Specific zones for each lot are not restated in the historic chapter — verify with Whittier Zoning .
Key design controls: Emphasis on retaining character-defining features, materials and siting; any discovered potential resource > 50 years old must be determined by Council prior to demolition permits (§ 18.86.020 and § 18.86.*) .
Where it applies: The chapter lists parcel addresses and a boundary map in § 18.86.020; check the official map on file with the Planning Department for parcel-level applicability .

Hadley/Greenleaf Historic District (Historic District No. 1) (Chapter 18.87)

Purpose: Preserve and enhance architectural and historic integrity; ensure new work is compatible (§ 18.87.010) .
Typical permitted uses: Predominantly single-family residential (some conversions to multi‑family noted historically); underlying zone rules still control permitted uses. Any work requiring a building permit needs a COA (§ 18.87.050) .
Key dimensional / design expectations: Compatibility with existing scale, massing, roof forms, porches/entries, materials and landscaping is required. The district guidance highlights roof forms (pitched roofs typical), materials (wood, brick, stone), and maintaining rhythm/spacing; numeric setbacks and lot coverage are not specified in the district chapter — verify with Whittier Development Standards and the property's zone (§ 18.87.*) .
Where it applies: Boundaries are defined in § 18.87.020 (map exhibits referenced) — review the chapter map for exact lots on file with Planning .

Central Park Historic District (Chapter 18.88)

Purpose and scope: Chapter establishes COA findings and special demolition/infill review rules for the Central Park historic district (§ 18.88.070–090) .
Typical permitted uses: Residential character; permitted uses default to underlying zoning but exterior work and infill are subject to COA (§ 18.88.*) .
Key controls: COA required for demolition, relocation or exterior changes; demolition triggers a 45‑day review and possible additional stay up to 180 days while preservation alternatives are explored (§ 18.88.090) .
Where it applies: See Chapter 18.88 for district map and notification rules (§ 18.88.*) .

College Hills Historic District (Chapter 18.89)

Purpose: Protect district integrity and control new/moved structures (§ 18.89.*) .
Typical permitted uses: Primarily residential; moving structures into district or constructing infill requires prior COA approval (§ 18.89.120) .
Key controls: No structure may be moved into the district without prior COA; moved-in structures over 50 years old will be evaluated as contributing vs. non‑contributing prior to final permits; vacancy/new infill must reflect district architectural heritage (§ 18.89.120) .
Where it applies: Boundaries defined in the College Hills chapter — consult the chapter map and Planning Department records for parcel-level applicability (§ 18.89.*) .

Most decision‑relevant standards / actions (table)

Decision or Standard	What it means in practice	Code Reference
Applicability (age)	Applies to resources 50 years or older	§ 18.84.030
When COA is required	Any exterior alteration, addition, restoration, rehabilitation, remodeling, demolition or relocation of a historic resource; also work to exterior of non‑contributing resources in a district; and infill/new improvements in a district	§ 18.84.150
Secretary waiver	Secretary can issue a waiver for minor work (e.g., roofing, foundations, some fences, landscaping, non‑contributing signs) if consistent with guidelines; determinations within 30 days	§ 18.84.170–180
Demolition review/stay	Demolition/relocation may trigger a 45‑day review and up to 180‑day stay to seek preservation alternatives; archival photodocumentation required before demolition in many cases	§ 18.84.090; § 18.88.090; § 18.84.400–420
Findings required for COA	Proposed work must not detrimentally change significant features or historic character; other specific findings apply for demolition/economic hardship	§ 18.84.200–210
Infill/new construction	Must be compatible with architectural style, height/width/length, massing, setbacks and materials of contributing resources (design guidance, not numeric overrides)	§ 18.84.430
State Historic Building Code	SHBC may be used for rehabilitation/preservation projects — alternate building regulations apply	§ 18.84.440
Adaptive reuse across zones	Former commercial buildings in residential zones can be adaptively reused as C‑2/C‑1/C‑0 non‑residential uses via a Conditional Use Permit plus COA where exterior changes occur	§ 18.84.490
Mills Act	City recognizes Mills Act agreements (tax incentive contracts) and ties them into the permit/recordation and validity rules	§ 18.84.040(K); § 18.84.470

Checklist (what an applicant must satisfy before work starts)

Confirm the property’s status: listed, eligible, or not listed on the City’s Local Official Register (verify with Planning) (§ 18.84.110) .
If the structure is ≥ 50 years old, assume historic-review applicability and consult the Historic Resources Commission/Secretary (§ 18.84.030) .
Submit a Certificate of Appropriateness application (or request a waiver) with plans, materials, colors, site plan, photos and any justification for demolition or relocation (§ 18.84.160; district application lists) .
For demolition proposals, prepare archival photodocumentation and a replacement plan (demolition approval often conditioned on approved replacement) (§ 18.84.090; § 18.84.420) .
Expect public notice to owners/occupants within 100 feet and minimum neighboring property counts; attend hearings as required (§ 18.84.090) .
If proposing adaptive reuse that changes use category, plan for a Conditional Use Permit per zoning (C‑2/C‑1/C‑0) in addition to COA if exterior changes are proposed (§ 18.84.490) .
Coordinate parking, setback and other dimensional questions with standard Whittier Parking and Whittier Development Standards because historic chapters require compatibility but do not substitute numeric zone rules (§ 18.84.430) .
If using alternate code provisions, reference the California Building Standards Code and the SHBC provision in the ordinance (§ 18.84.440) .

Risks & Ambiguities

Issue	Why it matters	What to verify
Numeric dimensional standards not stated in historic chapters	Historic chapters require compatibility (massing, setbacks) but do not list numeric setbacks, heights, lot coverage — could conflict with zoning tables	Verify the underlying zone's numeric standards at Whittier Zoning and Whittier Development Standards; ask Planning for parcel‑specific interpretation (§ 18.84.430)
Whether a building qualifies as a “historic resource”	The distinction (eligible vs. listed vs. non‑contributing) drives review triggers and notification	Confirm official status on the City’s Local Official Register; the Secretary can remove items from eligibility list (§ 18.84.080; § 18.84.110)
Demolition and replacement sequencing	The code generally prohibits demolition without approved replacement and allows stays up to 180 days	For demolition, expect the 45‑day/180‑day stay procedure and archival photography requirement; verify exact schedule and whether exemptions apply (unsafe/dangerous conditions) (§ 18.84.090; § 18.84.400)
COA vs building permit timing	Code says no permit shall be issued until COA or waiver is granted	Confirm COA waiver threshold with the Secretary; get written determination before submitting for building permits (§ 18.84.150–170)
Historic district boundary lines	A parcel may lie close to or straddle a boundary (map exhibits referenced in each chapter)	Verify the official boundary map on file with Planning — district chapters list addresses and maps (e.g., Earlham Chapter § 18.86.020)
Mills Act questions (tax impacts)	Mills Act is referenced but tax/legal details are under state law	The ordinance recognizes Mills Act contracts (§ 18.84.040(K)) but tax consequences are governed by Government Code—consult City and a tax/real‑estate attorney for enrollment

Plain-English Summary

If your Whittier property is around 50 years old or older, exterior changes, additions, demolition, moving the building, or most infill work will usually require a Certificate of Appropriateness (or a waiver) from the Historic Resources Commission (or the secretary for minor repairs). The code favors retaining historic features, requires compatibility for new construction, pauses demolition while alternatives are explored, and ties rehabilitation to the State Historic Building Code when applicable (§ 18.84.*) .

Frequently asked questions

What makes a property eligible for historic designation in Whittier?

A property must meet the National Register or California Register criteria or one of the local criteria such as representing a distinct period, association with a local person or event, exemplary architecture, or being a familiar visual feature. The Council applies these criteria when designating a landmark or district (§ 18.84.050; § 18.84.060) .

Do I need a Certificate of Appropriateness to replace my roof in a historic district?

Minor repairs and roofing can qualify for a secretary waiver if they are consistent with the guidelines; the secretary must make a determination within 30 days (§ 18.84.170–180). If the change significantly alters appearance, a full COA is required (§ 18.84.150) .

How long can the city delay a demolition for a historic structure?

For demolition/relocation, the Commission can impose an initial 45‑day review and extend the stay up to 180 days to explore preservation alternatives; before demolition the applicant typically must provide archival photodocumentation (§ 18.88.090; § 18.84.090) .

Can I convert a historic commercial building in a residential zone to another use?

Yes — adaptive reuse of a formerly legal commercial building in a residential zone to certain non‑residential uses in C‑2, C‑1 or C‑0 is allowed subject to a Conditional Use Permit and COA for any exterior changes (§ 18.84.490) .

Are there numeric setback or height exceptions for historic buildings?

The historic code requires new construction and alterations to be compatible in height, massing and setbacks with contributing resources, but it does not list specific numeric setbacks or heights. Numeric standards remain in the underlying zoning/development standards — verify parcel specifics with Whittier Development Standards and the Planning Department (§ 18.84.430) .

What is the City’s timeline for COA decisions?

The secretary determines completeness within 30 days; if a COA is required, after completeness the matter is scheduled for Commission action and the Commission acts within 30 days of receiving the recommendation. Appeals have separate timelines (§ 18.84.170; § 18.84.190) .

Can I build an ADU on a historic property?

Small ADUs may be permitted under specific provisions: the ordinance allows conversions to ADUs or JADUs with conditions and allows accessory ADUs ≤ 800 sq ft not visible from a public right‑of‑way in some cases, provided the conversion meets the referenced municipal code ADU standards (§ 18.84.180; see § 18.10.020 for ADU specifics) .

Who can nominate a property or district for designation?

Any person or group, including the city, may nominate a resource for designation by submitting an application to the Planning Department; applications must document how the resource satisfies designation criteria and pay fees unless city‑initiated (§ 18.84.070) .

If I disagree with a Historic Resources Commission decision, how do I appeal?

Commission determinations become effective after the appeal period (often 15–30 days depending on the chapter); appeals are processed to the City Council according to the appeal procedures in § 18.84.290 and the chapter‑specific appeal subsections (§ 18.86.130; § 18.89.130) .

Does the State Historic Building Code apply to Whittier historic projects?

Yes. Whittier’s code explicitly references the California State Historic Building Code (SHBC) as the alternate code for rehabilitation, preservation, restoration or relocation of surveyed historic resources (§ 18.84.440) .
