Capitola — Nonconforming Uses

Last reviewed: July 3, 2026

Overview

Capitola’s rules for nonconforming uses, nonconforming structures, and nonconforming parcels are in Chapter 17.92 of the zoning code. The chapter defines what is nonconforming, sets different rules for unimproved vs. improved parcels, creates a special amortization rule for the R‑1 district, and limits structural alterations and rebuilding after disaster. See the definitions and applicability in § 17.92.010–030 for the baseline rules.

NOTE (quick links used below): this page discusses zoning topics; see the city’s overall Capitola zoning & planning overview and related pages for neighborhood standards and permit processes. I mention local parking rules and development setbacks where they affect nonconforming status — see the city’s Capitola Parking and Capitola Development Standards pages for the full tables. When design-review or overlay rules are relevant I point to Capitola Design Review and Capitola Overlay Districts. For ADU interactions and state limits, see Capitola ADUs and the California Building Standards Code.

What the code says (core rules)

• Applicability: Chapter 17.92 applies to all zoning districts in Capitola. § 17.92.020.
• Definitions: “Nonconforming activity (use)”, “nonconforming structure”, and “nonconforming parcel” are defined in § 17.92.030 (and related glossary entries). Development standards that create structural nonconformity include setbacks, height, and lot coverage; the Uniform Building Code rules are treated separately. § 17.92.030.
• Unimproved lots with small structures: a nonconforming activity on a parcel with total structures of 400 sq ft or less may continue for five years after it became nonconforming; cessation > 90 days ends the nonconforming right. § 17.92.040.
• Improved lots (general rule except R‑1): nonconforming activities with structures totaling over 400 sq ft may continue but the area of activity may not be enlarged; inactivity >90 days terminates the right. Parking-only nonconformities have a special cross-reference to the parking chapter (17.76.020(C)(2)). § 17.92.050.
• R‑1 (single-family) special rules — amortization: nonconforming activities in R‑1 must be discontinued by June 26, 2019 or 50 years from the date the activity became nonconforming, whichever is later, except for limited exceptions for duplexes and council‑granted extensions for larger residential projects. § 17.92.060(A–C).
• Structural alterations: permitted so long as cumulative structural alteration work in the previous five years does not exceed 80% of the structure’s present fair market value (excluding permit/architect/landscape costs). The building official determines the cost estimate. § 17.92.070.
• Rebuilding after destruction: a destroyed building may be rebuilt if there is no increase in size or intensity, and repair cost (excluding permits/architect) does not exceed 90% of fair market value pre‑loss. § 17.92.080.
• Transient rentals: amortization for transient (vacation rental) uses expired under prior ordinance action; vacation rental uses are now only permitted inside the vacation rental overlay. § 17.92.090.

Below is a district-by-district practical breakdown that shows where those nonconforming rules intersect with the city’s district standards.

R‑1 — Single‑Family Residential

• Purpose and where it applies: the R‑1 district regulates detached single‑family housing throughout residential neighborhoods (see Chapter 17.16). Development standards for R‑1 are in § 17.16.030 (Table 17.16‑2).
• Typical permitted uses: single‑family dwellings (and accessory structures/ADUs governed elsewhere), with accessory uses per Chapter 17.52. § 17.16.030.
• Key dimensional standards (decision‑relevant): front setback ground floor 15 ft / garage 20 ft / second story 20 ft; maximum height 25 ft; minimum parcel area 5,000 sq ft for new parcels (existing smaller lots are grandfathered per subdivision rules). See Table 17.16‑2 and FAR rules. § 17.16.030.
• How nonconforming rules change things here: R‑1 has an explicit amortization rule — nonconforming activities must be discontinued by June 26, 2019 or after a 50‑year amortization period in many cases; nonconforming duplexes are allowed to continue indefinitely but cannot be enlarged and may be altered or rebuilt only under the structural alteration / destruction rules. § 17.92.060.
• Practical note: if a property’s nonconforming status stems from density (more dwelling units than current R‑1 allows), the owner may apply to city council for extensions under the findings set out in § 17.92.060(C).

RM‑M — Residential, Medium‑Density (multifamily)

• Purpose: allows multifamily housing subject to the multifamily objective standards in Chapter 17.82 and RM development tables. § 17.16 / 17.82.
• Typical permitted uses: multifamily dwellings; single‑family on RM must follow R‑1 standards. § 17.16.030(C).
• Key dimensional standards: RM references the multifamily standards (objective standards) and uses R‑1 for single‑family; see Table 17.16‑5 and Chapter 17.82 for height, setbacks, and open space. § 17.16.030 and 17.82.
• Nonconforming interaction: Chapter 17.92 applies to RM the same as other zones; structural alteration limits (80% rule) and rebuilding (90% rule) apply. § 17.92.020, 17.92.070–080.

MU‑N and MU‑V — Mixed‑Use Neighborhood / Mixed‑Use Village

• Purpose: MU‑N and MU‑V allow mixed residential/commercial use in neighborhood and village contexts (see § 17.20.010). Development standards for MU‑N are in § 17.20.040 (Table 17.20‑3); MU‑V standards are in § 17.20.030 and include the -VR overlay rules. § 17.20.
• Typical permitted uses: mixed commercial at ground floor with residential allowed on upper floors (MU‑V) and constrained residential patterns in the -VR overlay. § 17.20 / Table 17.20‑3.
• Key dimensional standards (examples): MU‑N front setback min 0 ft (or 10 ft from curb) up to 25 ft, maximum height 27 ft, FAR 1.0; MU‑V has its own table—consult § 17.20.030. § 17.20.040.
• Nonconforming interaction: nonconforming commercial or mixed uses continue under § 17.92.050 (cannot be enlarged; 90‑day inactivity rule). Parking‑only nonconformities are treated with reference to the parking chapter; check Capitola Parking and § 17.76.020(C)(2).

C‑C and C‑R — Commercial Core / Commercial Retail

• Purpose and where it applies: central corridors and neighborhood commercial areas (Chapter 17.24). § 17.24.030.
• Typical permitted uses: retail, restaurants, offices, lodging with conditional uses defined in Table 17.24‑1 and Table 17.24‑3. § 17.24.
• Key dimensional standards: baseline height 40 ft, FAR 1.0 (C‑C); front/property setbacks and special rules for parcels fronting Capitola Road (height 35 ft and 40 ft rear setback in that location). § 17.24.030.
• Nonconforming interaction: the general nonconforming rules allow continuance (no enlargement) under § 17.92.050; structural alterations conform to § 17.92.070. § 17.92.050–070.

CF and P/OS — Community Facilities / Parks & Open Space

• Purpose: public/quasi‑public uses and resource protection; heavy limits on new structures on beach/open sandy areas. See § 17.32.020–030 and Table 17.32‑1. § 17.32.020–030.
• Typical permitted uses: parks, public facilities, limited community uses; commercial only as accessory with CUP in P/OS. § 17.32.020.
• Nonconforming interaction: Chapter 17.92 applies; where the community director finds a use inconsistent with the purpose of P/OS, it may be prohibited — verify with the director. § 17.32.020(D) and § 17.92.020.

Quick reference table — most decision‑relevant nonconforming rules

Checklist (what an applicant must do)

• Confirm whether the existing use/structure was lawfully established and identify the nonconforming category (use, structure, or parcel) per § 17.92.030.
• Measure total area of structures: is it ≤ 400 sq ft (unimproved lot rule) or > 400 sq ft (improved lot rule)? Use § 17.92.040–050.
• If in R‑1, determine whether amortization applies (dates/50‑year rule) and whether duplex exception or council extension is possible; review § 17.92.060.
• For proposed structural alterations, obtain a building official cost determination and ensure the 5‑year cumulative cost test does not exceed 80% of FMV. § 17.92.070.
• If the building was destroyed, calculate repair cost vs. FMV (exclude permits/architect/landscape) to check the 90% threshold before rebuilding. § 17.92.080.
• Check related standards that define the nonconformity (setbacks, height, lot coverage) in the applicable zoning chapter (example: R‑1 standards at § 17.16.030, MU‑N at § 17.20.040, C‑C/C‑R at § 17.24.030).
• If the nonconformity is parking‑only, verify the parking chapter exemption and cross‑references: § 17.76.020(C)(2) (parking chapter). Noted in § 17.92.050.
• Verify whether design review, overlays, or historic rules affect your site (see Capitola Design Review, Capitola Overlay Districts, Capitola Historic Preservation). Verify with the jurisdiction for parcel‑specific interpretations.

Risks & Ambiguities

Plain‑English summary

Capitola lets many lawful-but-now-nonconforming uses and structures continue, but with limits: small/unimproved setups (≤400 sq ft) get a five‑year runway, most bigger nonconformities may stay but cannot be enlarged and will be lost if inactive for 90 days, and R‑1 residential nonconformities face an amortization schedule with special duplex exceptions — major alterations and rebuilding are limited by 80% and 90% cost tests respectively. Always verify the precise facts of your parcel with the Community Development Director. § 17.92.030–080 provide the controlling rules.
