Hollister — Historic Preservation

Q: Where do I check setbacks, lot coverage and height limits for my Old Town property?

Refer to Table 17.04‑3 (lot width/depth/coverage/height) and Table 17.04‑4 (yard setbacks) in the residential standards under § 17.04.030 , then confirm with staff for parcel‑specific interpretations (corner lots, alleys, small lot categories).

Overview

Hollister’s zoning ordinance treats historic preservation as a site-sensitive overlay of normal zoning: the Old Town/Monterey Street neighborhoods and identified landmarks have special design standards, allowances, and exemptions that alter how development, ADUs, and nonconforming structures are reviewed. Key protections are embedded in the Old Town design standards, the Home Office district rules, nonconforming-use exemptions for historic resources, and ADU-specific provisions that limit visibility and require deed restrictions. See the municipal code excerpts at § 17.04.050, § 17.06.010, § 17.24.220 and Chapter 17.32 for ADU rules.

How Hollister’s code applies (district-by-district)

Old Town — OT-M (Old Town Medium)

Purpose: Preserve the historic small‑town residential character of early Hollister and allow modest infill consistent with pre‑WWII architectural styles. § 17.04.050 describes the Old Town design objective (architectural styles, porches, raised foundations, compatible massing).

Typical permitted uses: single‑family, duplexes, cottages and limited small‑scale multi‑family consistent with the district. Dimensional/character standards: front yard 15 ft, interior side 5 ft, building heights limited to historic‑scale (e.g., dwellings ~30 ft, one‑and‑one‑half story allowed for certain types); see Table 17.04‑3 and Table 17.04‑4 for exact yard, height and lot coverage numbers. (See § 17.04.030 / Table 17.04‑3 & Table 17.04‑4.)

Where it applies: The Old Town zone covers the "original town" neighborhoods (including areas listed in the Monterey Street National Historic District). Design review: infill/additions in OT districts are subject to Old Town supplemental design standards and may be referred to Site & Architectural Review depending on project scale. § 17.04.050.

Old Town — OT-H (Old Town High)

Purpose: Allow higher‑density infill north of Fourth Street while preserving compatibility with historic massing. Uses: small multi‑family, townhouse, apartments (subject to stricter design review where massing risks historic character). Dimensional: similar setbacks to OT‑M (15 ft front, 5 ft side interior), different lot coverage and height caps (see Table 17.04‑3). § 17.04.030 – 17.04.050.

Special Old Town notes: Exceptions to minimum lot size may be allowed for subdivisions that preserve historic residences if the City records a deed restriction preventing demolition for 10 years and the Planning Commission makes the findings described in the code.

Home Office — HO (Home/Office)

Purpose: A combining district that preserves residential and historic character while allowing small, compatible office and cottage‑commerce uses in areas adjacent to downtown (portions lie within the Monterey Street National Historic District). § 17.06.010 – 17.06.020.

Typical permitted uses and permit classes: Accessory Dwelling Units (ADUs) (ADU permit), professional offices (APR), artist studios (CUP) and small residential types; see Table 17.06‑1 for a full list and permit triggers. Key development standards default to the Old Town (OT‑M) development standards for residential uses. § 17.06.020 / Table 17.06‑1.

Where it applies: Neighborhood blocks near downtown where preserving historic fabric is explicit in the district purpose. Projects with business signage are also constrained by the sign chapter and Old Town design rules.

Downtown Hollister Historic District & Monterey Street Historic District (named places)

What they control: The code recognizes locally designated historic districts (including the Monterey Street National Historic District and Downtown Hollister Historic District) and applies specific prohibitions and compatibility expectations: for example, outdoor vehicle sales are prohibited inside those districts. The Old Town/OT and Home Office rules emphasize that new construction match historic scale and details. (See § 17.04.030 and related Old Town notes.)

Key standards & decision‑relevant table

Item / Topic	What the code requires in practice	Code Reference
Historic exemption from nonconforming rules	A building listed on a Federal, State or local historic registry, or a contributing building in a city‑recognized historic district, is exempt from the nonconforming regulations that otherwise apply to buildings/uses.	§ 17.24.220(B)
Planned Development cannot dilute preservation	A Planned Development may not be used to reduce design or preservation requirements for structures designated as historical.	§ 17.66.080(E)
Old Town design standards (typical)	New infill must reflect pre‑WWII styles (Craftsman, Italianate, Queen Anne, etc.), porches, raised foundations, garages set behind front plane.	§ 17.04.050
Old Town setbacks (representative)	Front: 15 ft, Side: 5 ft (interior), Rear: 10 ft or 15 ft to alley centerline (OT‑M / OT‑H; see tables for variations).	Table 17.04‑4/§ 17.04.030
ADUs in historic districts	ADUs on lots within a historic district or on listed properties must either be not visible from the public right‑of‑way or be entirely contained within the existing dwelling; ADU permit & deed restriction rules also apply.	Chapter 17.32 (development standards) and § 17.32.050 (permit application requirements)

Notes on the table: where the ordinance uses tables (Table 17.04‑3 / 17.04‑4) the exact lot width, depth, height and coverage numbers are in those tables; see § 17.04.030 and accompanying tables.

Practical guidance / plain‑English synthesis

If a property is a listed historic structure or within the city‑recognized historic district, it receives protective treatment (exemptions from nonconforming‑use enforcement) but also faces stricter design compatibility expectations under the Old Town standards. Verify whether the building is on a local/state/federal register before designing or permitting changes (§ 17.24.220).
Additions, ADUs, and infill in Old Town or the Home Office zone must match scale, porches, roof forms and materials favored by the ordinance; site plans and elevations that preserve the street façade rhythm increase your chance of a ministerial or favorable design review decision (§ 17.04.050; § 17.06.010).
ADUs are allowed in historic districts but the ordinance restricts visibility from the street (no highly visible new detached ADU in a historic district unless it’s fully hidden or within the existing residence) and requires administrative permit package items and deed restrictions (see Chapter 17.32, § 17.32.050).
A Planned Development cannot be used to waive preservation or Old Town design rules; don’t assume PD rezoning will let you ignore historic protections (§ 17.66.080(E)).
For site design elements that frequently matter in historic areas — like parking layout and garage placement — follow the Old Town guidance (set garages behind the house; screen mechanical equipment) and consult the city’s parking chapter for counts and placement. See the parking and development standards pages for process and metrics.

Checklist — what an applicant must satisfy (typical)

Confirm whether the parcel/building is on any historic registry or within the Monterey Street or Downtown Historic District (city/county/state/federal). Verify with the jurisdiction. (§ 17.24.220)
Follow Old Town design standards for massing, porches, roof forms, materials and proportion if in OT‑M/OT‑H or HO zones. (§ 17.04.050; § 17.06.010)
If proposing an ADU, prepare the administrative permit package per § 17.32.050 (application, preliminary title report, utility info, and deed restriction as required) and ensure the ADU meets the historic‑district visibility/containment rule. (§ 17.32.050; Chapter 17.32 standards)
Use the applicable tables (Table 17.04‑3 / Table 17.04‑4) to confirm setbacks, lot coverage, heights and lot sizes; where your proposed changes are inconsistent, expect design review or conditional permits. (§ 17.04.030; Table 17.04‑3/4)
Where historic features will be altered/demolished, prepare documentation and be ready for discretionary review; demolition/rehab may trigger additional findings or CEQA review. Verify with the jurisdiction.
Anticipate sign and streetscape constraints in historic districts; consult the signage page and § 17.20 provisions if the project includes commercial uses.

Risks & Ambiguities

Issue	Why it matters	What to verify
Is the property actually "listed" or only adjacent to a historic district?	Code treats listed resources differently (exemptions, stricter design expectations). Mis‑classification leads to wrong permit path.	Confirm registry status with Development Services / City Clerk and ask for written confirmation. (§ 17.24.220)
ADU visibility rule — what counts as "visible from the public right‑of‑way"?	Design acceptance hinges on whether an ADU can be seen from sidewalks/streets; ambiguous viewshed definitions can trigger discretionary review.	Request an early pre‑application meeting; ask staff to confirm whether the proposed ADU elevation/roofline is considered visible. (Chapter 17.32; § 17.32.050)
Exact table numbers for setbacks/coverage on a given lot	The Old Town tables have multiple entries depending on lot type (small lot, corner, alley) and mistakes cause rejections.	Use Table 17.04‑3/17.04‑4 and confirm park/frontage/alley status with staff. (§ 17.04.030; Tables 17.04‑3/4)
Planned Development attempts to alter preservation rules	Code explicitly stops PDs from weakening preservation; relying on PD relief can be denied.	If pursuing PD flexibility, get written determination from Planning on whether proposed relief "touches" preservation requirements. (§ 17.66.080(E))
Parcel‑specific conflicts with State ADU law	State ADU law limits some local restrictions; local ADU chapter references state law but local practice must match state requirements.	Confirm with staff that the local ADU standards you’re relying on conform to state ADU law (Chapter 17.32 references). (§ 17.32 and § 17.32.050)

Plain‑English Summary

If your property is in Hollister’s Old Town or Monterey Street historic areas, the city expects changes to match historic scale and details, gives special protections to listed historic buildings, allows ADUs but restricts visible new detached ADUs in historic places, and requires specific permit materials and deed restrictions for ADUs; confirm registry status and run plans through Development Services early. (§ 17.04.050; § 17.24.220; Chapter 17.32; § 17.32.050)

Frequently asked questions

What counts as a "historic structure" in Hollister and what protections does it get?

A "historic structure" for Hollister’s zoning purposes is one identified on a Federal, State, or local historic registry; such structures and contributing buildings in a city‑recognized historic district are exempt from the nonconforming regulations that would otherwise apply. See § 17.24.220(B) for the code language and implications.

What design rules apply if my house is in the Old Town (OT‑M) district?

Old Town supplemental standards require infill and additions to reflect pre‑WWII styles (porches, raised foundations, compatible massing), and the OT tables set setbacks and height caps (for example, 15 ft front setback; interior side 5 ft). See § 17.04.050 and the residential tables under § 17.04.030 / Table 17.04‑3 & 17.04‑4.

Can I build an ADU on a lot inside the Monterey Street Historic District?

Yes — ADUs are allowed, but Hollister’s ADU provisions require that an ADU on a lot within a historic district either be not visible from the public right‑of‑way or be entirely contained within the existing dwelling. ADU permit filing and deed‑restriction rules also apply. See the ADU chapter (Chapter 17.32) and § 17.32.050 for application requirements.

Do historic buildings get special treatment for nonconforming setbacks or uses?

Yes. A historic structure or a contributing building in a city‑recognized historic district is exempt from the nonconforming provisions (so long as it is listed per the code's definition). Refer to § 17.24.220(B).

If I want to change a historic building, do I need a Planned Development or variance?

You may need design review, site & architectural review, or a Conditional Use Permit depending on the scope. Importantly, a Planned Development cannot be used to reduce any preservation or design requirements that the code mandates for a designated historic structure (§ 17.66.080(E)). Verify permit type with Development Services.

What are the ADU permit submittal requirements in Hollister?

The ADU administrative permit application must include the city application form, a preliminary title report (dated within six months), utility/service information, and any required deed restriction to be recorded before building permit issuance. See § 17.32.050 for the detailed list.

Are there parking exceptions for ADUs in historic districts?

Yes. The ADU provisions waive replacement or new off‑street parking in certain circumstances, including when the ADU is in an "architecturally and historically significant historic District." See the ADU standards in Chapter 17.32 and the parking chapter for how parking is measured.

Can a Planned Development reduce Old Town design or preservation standards?

No. The ordinance explicitly prohibits using a Planned Development to reduce design or preservation requirements for any structure designated as historical; expect the Planning Commission to deny such requests unless they meet other code test. § 17.66.080(E).

Where do I check setbacks, lot coverage and height limits for my Old Town property?

Refer to Table 17.04‑3 (lot width/depth/coverage/height) and Table 17.04‑4 (yard setbacks) in the residential standards under § 17.04.030, then confirm with staff for parcel‑specific interpretations (corner lots, alleys, small lot categories).

Do I need design review for exterior alterations in Old Town?

Probably. The Old Town supplemental standards direct that additions and infill be compatible and some projects (especially multi‑unit or larger alterations) are subject to Site & Architectural Review or the Development Review Committee. Check the City’s design review process early in planning. ---
