Placentia — Historic Preservation

Last reviewed: July 2, 2026

Overview

Placentia’s historic-preservation rules are centered in the Placentia Historical Resources Ordinance and several site-specific plan chapters. The city requires review and permits for demolition, substantial alteration, or relocation of identified historical resources and embeds preservation goals into district standards for Old Town Placentia (OT) and the TOD / Packing House area. Key standards reference the Secretary of the Interior’s treatment standards and CEQA review. § 23.06.010–050 contains the core historic-resources rules.

What the ordinance controls (core rules)

• No demolition, substantial alteration, or relocation of an historical resource without a permit and referral to the Planning Commission, except when the Building Official or City Engineer finds immediate necessity for public safety (see § 23.06.040).
• Permit applications for demolition/alteration/relocation are made to the Administrator and are processed per the city’s use-permit procedures (Chapter 23.87); applicants must pay fees and deposits that permit CEQA evaluation (14 CCR § 15064.5) (see § 23.06.050).
• Approvals for substantial alteration must demonstrate compliance with the Secretary of the Interior’s Standards for Rehabilitation and must preserve the character-defining historic features (see § 23.06.050(a)(1)–(2)).
• Approvals for demolition require a professional structural evaluation prepared by an architect or engineer meeting the Secretary of the Interior’s Professional Qualification Standards (36 CFR Part 61) and CEQA review (see § 23.06.050(b)(1)–(2)).

District-by-district breakdown (where historic rules matter)

Old Town Placentia (OT)

Purpose and emphasis:

• The Old Town Placentia chapter explicitly aims to “preserve and highlight historic features” and maintain the small‑scale, shopfront village character of Old Town (purpose language). § 23.112.010.

Subareas and where it applies:

• Old Town is divided into subareas: Main Street (MS), Village (V), Mixed-Use (MU), High-Density Residential (HDR), Public Facilities (PF), plus an R-2 Overlay Zone; the chapter applies to parcels shown on the Old Town map. § 23.112.030–040.

Typical permitted uses and permits:

• Land uses are controlled by Table 1 in the Old Town chapter; uses may be Permitted (P), Conditionally Permitted (UP), or Not Permitted (NP). New construction requires development plan/site plan review and design/architectural review (see § 23.112.040 and related tables).

Key development standards:

• Old Town standards prioritize pedestrian-scale architecture, mixed uses on qualifying lots, public art, plazas, and enhanced streetscape elements. Projects may face extra public-realm fees and streetscape installation requirements. § 23.112.010, § 23.112.090–100.

Practical note:

• Old Town includes special amortization and nonconforming use rules (e.g., notification requirements) and explicit exemptions for certain historic parcels (see § 23.112.080 and related notices). Verify applicability to a parcel using the official Old Town map. § 23.112.020–030, § 23.112.080.

(When you see references to sidewalks/streetscape or required parking, those invoke the city’s Parking standards and Development Standards.)

TOD / Packing House District (TOD)

Purpose and emphasis:

• The TOD / Packing House district preserves and encourages adaptive reuse of the historic Packing House and adjacent areas. The district explicitly encourages adaptive reuse and public art that reflect local history. § 23.111.* (multiple subsections) and purpose language.

Site-specific historic rule:

• The Packing House building at 341 S. Melrose Street is treated as an historic resource eligible for the California Register; adaptive reuse provisions and some exemptions (for amortization and TOD requirements) are spelled out in the TOD chapter. See notes and exemptions in the TOD/ Packing House chapters. § 23.111.040 and accompanying notes.

Design and review:

• Projects in the TOD zone require high-quality architectural review and third‑party review (applicant pays third‑party costs). Parking for adaptive-reuse projects may be subject to adjusted onsite requirements or parking studies by a traffic engineer. § 23.111.040(a)–(b).

Practical note:

• The TOD chapter allows more flexibility for adaptive reuse but requires discretionary review, design controls and payment of TOD impact/public-realm fees. Verify which TOD subrules apply to a parcel. § 23.111.070–080.

Site‑specific plan protections (examples)

• Wagner House: Chapter 23.101 establishes site-specific preservation requirements (the Wagner House must be renovated and maintained to preserve historic characteristics; exterior architecture cannot be modified outside approved plans). § 23.101.020–060.
• Lewis Lemke House: Specific Plan 2 (Chapter 23.102) governs the 414 N. Placentia Ave site; exterior architecture cannot be modified and the plan sets specific height and use limits to protect historic character. § 23.102.010–050.

These site-specific chapters override or add to general rules; always check the individual chapter that applies to the parcel.

Other districts and references

• The city’s zoning district list includes R-A, R-1, R-2, R-G, R-3, RPC, T-C, P-V, C-O, C-1, C-2, C-M, M, PMD, MHP, O, O-1, PUD, SP-1…SP-8, TOD, OT. Historic resources can appear in any of these zones; the Historical Resources Ordinance applies citywide where properties are designated historical resources. § 23.08.010 and Chapter 23.06.

Key decision‑relevant standards and uses (quick reference)

Checklist — What an applicant must satisfy for work affecting an historical resource

• Confirm whether the property is an historical resource (city list, Old Town map, or state register). Verify with the jurisdiction. § 23.06.030.
• If demolition, relocation, or substantial alteration is proposed, submit a permit application to the Administrator and pay the required fee/deposit for CEQA review. § 23.06.050.
• For substantial alteration: demonstrate compliance with the Secretary of the Interior’s Standards for Rehabilitation (include preservation/rehab approach in submittal). § 23.06.050(a)(1).
• For demolition: provide a structural/feasibility report by a qualified architect/engineer meeting 36 CFR Part 61 standards. § 23.06.050(b)(1).
• Expect Planning Commission review (public hearing) and CEQA compliance. § 23.06.040–050.
• If project is in Old Town (OT) or TOD, include design/architectural materials, public-realm/street improvements, and parking strategy (may require a parking demand study). See Old Town § 23.112 and TOD § 23.111.
• For site-specific historic plans (e.g., Wagner House, Lewis Lemke House), comply with the approved site plan attachments and restrictions in Chapters 23.101 and 23.102.

Note: For design-review steps reference the city’s Design Review guidance and for parking impacts consult Parking.

Risks & Ambiguities

Plain‑English summary

If your building is listed (or eligible) as a historic resource in Placentia, you cannot demolish, move, or substantially change its exterior without a permit and Planning Commission review; the city requires preservation-minded plans that meet Secretary of the Interior standards, CEQA review, and potentially site-specific design controls in Old Town or the TOD/ Packing House area. Verify listing status and coordinate early with Planning. § 23.06.040–050, § 23.112.010–030.
