Overview

This page summarizes what the City of Lompoc's zoning ordinance requires for signs: who may place what signs, how sign area and height are measured, the numeric limits by zone and sign type, prohibited sign types, and where design-based flexibility or a Sign Program is required. All standards below are drawn from the City’s sign chapter and related sign-permit rules; citations point to the controlling code sections (see § 17.316.010 et seq.).

Note: this page covers only the local zoning/planning sign regulations (Chapter 17.316 and the Sign Permit chapter 17.540) and does not replace required electrical/building approvals under the California Building Standards Code.

How the Lompoc sign rules are organized (quick)

  • Purpose, applicability and exemptions: § 17.316.010–§ 17.316.020.
  • Measurement, materials, display limitations: § 17.316.050.
  • Permanent sign tables: Table 17.316.060.A (Residential zones) and Table 17.316.060.B (Non‑Residential zones) within § 17.316.060.
  • Temporary signs: § 17.316.070 and Table 17.316.070.A.
  • Prohibited signs and display restrictions: § 17.316.040.
  • Sign permits and Sign Programs: Chapter 17.540 (Sign Permit and Sign Program).

District-by-district breakdown

Notes on districts: the sign chapter differentiates between residential zones (applies to common residential districts such as R-1 and R-2 that are explicitly referenced in the code), the MU (Mixed Use) zone, the OTC (Old Town Commercial) zone, and other non‑residential zones (commercial/industrial). Where the code groups zones, I follow the same grouping and cite the table or paragraph that controls.

R-1 (Residential Single-Family)

  • Purpose / where it applies: standard single-family neighborhoods; permanent signs in residential zones are regulated via Table 17.316.060.A under § 17.316.060.A.
  • Typical permitted sign types: limited flag, monument (for multi‑family or complexes), wall, small yard signs, and directional signs; many residential signs require a permit. See Table 17.316.060.A.
  • Key dimensional standards: example caps in the residential table include a typical 24 s.f. maximum for a single wall or monument sign per street frontage and monument heights around 5 ft for residential contexts (see Table). Verify exact parcel allowances in Table 17.316.060.A.
  • Practical note: signs are more restricted in R-1/R-2 than in commercial zones; large commercial-style signage is not allowed unless a Sign Program is approved.

R-2 (Residential Multi-Family)

  • Purpose / where it applies: multi‑family residential areas; the same residential table Table 17.316.060.A governs sign types and counts.
  • Typical uses: wall/address signs or a single complex ID sign per street frontage (e.g., up to 24 s.f.), directional signs for emergency access are required for complexes with multiple street frontages. § 17.316.060.A.
  • Practical note: directional signs required for emergency response do not count toward the sign maximums.

MU (Mixed Use)

  • Purpose / where it applies: properties with mixed residential and commercial uses. If a parcel in MU contains only residential uses, it is subject to the residential table Table 17.316.060.A; otherwise non‑residential standards apply. See § 17.316.060 notes.

OTC (Old Town Commercial)

  • Purpose / where it applies: the Old Town Commercial zone is treated specially in the sign chapter and is designed to preserve the Old Town character. See § 17.316.080 for OTC-specific standards.
  • Typical permitted uses and special rules:
    • Monument signs are prohibited in the OTC.
    • Window signage in the OTC is limited to 25% of window area (for windows in the OTC). See § 17.316.080 and Table notes.
    • Portable signs are allowed in the City right‑of‑way in OTC with an Encroachment Permit and indemnification; minimum pedestrian clearance (6 ft) must be maintained.
  • Practical note: Old Town rules prioritize pedestrian-scale, historic-compatible signage — expect stricter design review and limits on monument/large free-standing signs.

Non‑Residential Zones (Commercial & Industrial)

  • Purpose / where it applies: all non‑residential zones are regulated by Table 17.316.060.B in § 17.316.060.B. That table sets the baseline allowances for permanent sign types and then Subsection C provides per-sign-type rules.
  • Typical permitted sign types: wall signs, monument signs, awning/canopy signs, projecting signs, directory signs, window signs, and others. Combined sign area for permanent signs is capped at two (2) square feet per one lineal foot of street frontage, with a maximum of 300 s.f. per business (see § 17.316.060.B).
  • Design incentives: the code allows incremental increases in area/height for preferred design elements (raised letters, native materials, reduced-height monuments) per § 17.316.030 and Table 17.316.030.B (cumulative increases up to 20% area / 15% height under certain conditions).

Decision‑relevant quick reference table

Sign Type Typical cap / limit Permit required? Key code reference
Wall Sign Generally tied to frontage: up to 2 s.f. per lineal foot (combined cap) and often 24 s.f. per frontage in residential contexts Yes (except limited interior signs) § 17.316.060; Table 17.316.060.A/B
Monument Sign Typical 24 s.f. and ~5 ft height in residential; non‑residential per table; prohibited in OTC Yes § 17.316.060; § 17.316.080 (OTC)
Window Sign Max 50% (general) / 25% in OTC; transparent exceptions may be approved by Director No (but counted toward limits for permanent in some zones) § 17.316.070; § 17.316.080
Awning/Canopy Sign 1 s.f. per lineal foot of awning width; copy max 60% of valance; vertical clearance 8 ft min Yes § 17.316.060.C.1
Banner Sign (temporary) 36 s.f. or 10% of frontage (whichever greater); display limits (60 days twice/yr) Permit required if >32 s.f. § 17.316.070.D.1; Table 17.316.070.A
Portable / A‑frame Typical 6 s.f. (portable), height 3 ft; allowed in OTC ROW with Encroachment Permit and indemnity Usually no (but ROW requires permit) § 17.316.070.D.3; § 17.316.080 (OTC ROW rules)
Prohibited types Pole signs, roof signs, feather flags, inflatable/tethered devices, people signs, off‑premises signs (except Sign Program) N/A § 17.316.040

Key measurement and design rules (what changes the math)

  • Sign area: enclosed with a continuous rectangle around all copy and elements (portable signs counted differently). § 17.316.050.B.1–2.
  • Double‑sided signs: measured as one side if separation ≤ 24 in. § 17.316.050.B.3.
  • Height: measured from finished grade to top of the highest element; the Director sets finished grade if fill proposed. § 17.316.050.B.6.
  • Design incentives: modest increases allowed for preferred materials or raised letters; cumulative increases cap at 20% area / 15% height for permanent signs. § 17.316.030 and Table 17.316.030.B.

Permit, program and enforcement essentials

  • A Sign Permit is required to erect, move, alter, replace, suspend, display, or attach a sign (each sign or copy change is a separate permit) except where the chapter specifically allows no permit. See § 17.540.020.
  • Sign Programs: a coordinated sign plan for multi‑tenant centers or where corporate standards conflict; corporate standards may be allowed within ±10% of chapter limits unless a formal Sign Program is approved. § 17.316.030; Chapter 17.540.
  • Enforcement: prohibited signs and violations carry misdemeanor/infraction penalties and potential removal (mobile billboard enforcement described). § 17.316.040 and follow‑on enforcement provisions.

Checklist (what an applicant must satisfy)

  • Confirm zone and which table applies (Residential Table 17.316.060.A vs Non‑Residential Table 17.316.060.B). § 17.316.060.
  • Measure sign area and height per § 17.316.050 (include framing and whether double‑sided math applies).
  • Confirm the sign type’s numeric cap (area, number, height) in the applicable Table and Subsection C (per sign type).
  • Submit a Sign Permit (Chapter 17.540) and, if applicable, a Sign Program for multi‑tenant or corporate deviations.
  • For signs encroaching into public ROW (e.g., awnings, portable signs in OTC), obtain Encroachment Permit and indemnity as required. § 17.316.060.C; § 17.316.080.
  • Ensure lighting complies with non‑flashing, no animation rules and that electrical work meets the California Building Standards Code. § 17.316.040.C.
  • If your site affects pedestrian/vehicle circulation or parking, check Lompoc Parking and site development standards at Lompoc Development Standards. Verify landscape screening obligations at Lompoc Landscaping and Screening.

Risks & Ambiguities

Issue Why it matters What to verify
Sign height baseline (finished grade) Height can change depending on which finished grade is used — affects whether a sign is over the cap Verify the finished grade determination with Planning Director; measurement rule § 17.316.050.B.6.
Multi‑tenant sign area allocation Total area cap is per business or per site (combined caps apply) — disagreement can cause denial Confirm whether the cap applies per business frontage or per site using Table 17.316.060.B and Sign Program rules § 17.316.060.B / 17.540.
OTC special rules (monument bans; 25% window area) Old Town has its own limits that override general tables Verify OTC applicability to parcel and apply § 17.316.080 (monument prohibition; 25% window limit).
Corporate sign deviations Corporate standards that deviate >10% require a Sign Program If using corporate sign specs, verify whether deviation >10% triggers Sign Program per § 17.316.030.
ROW/sidewalk placement (portable signs, awnings) Requires Encroachment Permit and indemnity; public safety/ADA clearance rules apply Confirm Encroachment Permit, indemnity, and maintain 6 ft pedestrian clear zone in OTC per § 17.316.080.

Plain‑English summary

Lompoc’s zoning code lets small, pedestrian‑scale signs in neighborhoods and larger business signs in commercial areas, but counts all permanent sign area against clear caps, restricts flashy or unsafe display types, and requires a Sign Permit (or a Sign Program for multi‑tenant/corporate exceptions). Follow the measurement rules, check OTC special limits (no monuments; smaller window signage), and get an Encroachment or electrical permit where the sign touches the public right‑of‑way or electrical systems. Verify with the City for parcel‑specific questions.

Frequently asked questions

What signs are allowed on a single‑family (R-1) lot in Lompoc?

Residential sign allowances are in Table 17.316.060.A. Typical permitted signs include one flag per parcel (up to 35 s.f.), small wall or monument signs (often 24 s.f. per street frontage), and yard signs within the temporary sign rules; some signs require a Sign Permit. See § 17.316.060.A.

How does Lompoc measure sign area and height?

Sign area is measured by enclosing the extreme limits of the sign copy and elements within a continuous rectangle; double‑sided signs with ≤24 in. separation are measured as one side. Sign height is measured from finished grade to the top of the sign, and the Director may set finished grade when fill is proposed. See § 17.316.050.

Do I need a Sign Permit to change the face on my business sign?

Yes. The code requires a Sign Permit to erect, move, alter, replace, suspend, display, or attach a sign; each sign and most copy changes require a separate Sign Permit except where the chapter specifically allows non‑commercial message changes. See § 17.540.020.

Are monument signs allowed in Old Town (OTC)?

No — monument signs are prohibited in the OTC Zone. Also, window signage in the OTC is limited to 25% of window area. See § 17.316.080.

Can a corporate sign program exceed the numeric limits in the code?

Corporate standards may deviate up to 10% from chapter limits without a Sign Program; deviations greater than 10% generally require Sign Program approval under Chapter 17.540. Confirm via § 17.316.030 and Chapter 17.540.

What temporary signs are allowed and for how long?

Temporary banners are allowed (typically 36 s.f. or 10% of frontage, display limits like 60 days twice per year for banners), portable and yard signs have specific area/number limits in Table 17.316.070.A, and temporary signs are not counted toward permanent sign area caps. See § 17.316.070 and Table 17.316.070.A.

If a sign projects over the sidewalk, what approvals are needed?

A sign or awning that encroaches into the City right‑of‑way requires an Encroachment Permit and compliance with vertical/pedestrian clearance rules (e.g., 8 ft clearance for awnings and minimum sidewalk clear zones in OTC). See § 17.316.060.C.1.f and § 17.316.080.

What sign types are explicitly prohibited in Lompoc?

Prohibited types include pole signs, roof signs, feather signs, inflatable/tethered devices, people signs, off‑premises signs (except per approved Sign Program), and signs with flashing/animated lighting or sound. See § 17.316.040.

Who is responsible for sign structural and electrical integrity?

Property owners are responsible for the structural and electrical integrity of signs on their property and must obtain required permits (includes electrical/building permits governed by state rules). See § 17.316.020 and § 17.540.020; coordinate with the California Building Standards Code.
