Solana Beach — Nonconforming Uses

Q: Can I rebuild my damaged nonconforming house in Solana Beach?

Yes — a legally existing nonconforming principal residential structure may be rebuilt to its pre‑existing building envelope if restoration is started within 3 years of damage and diligently completed within 18 months of permit issuance; restoration includes re‑establishing footprint, setbacks, height and parking that existed at the time of damage. See § 17.16.080(A).

Q: What happens if a nonconforming commercial building is more than 50% destroyed?

If a nonconforming nonresidential principal structure is destroyed by more than 50% of floor area or replacement value it may not be rebuilt in its nonconforming form — the rebuilt structure must be brought into conformance with current zoning; however, any preexisting nonconforming use may be resumed in the rebuilt conforming structure. § 17.16.080(B).

Q: How long can a nonconforming use continue in Solana Beach?

Nonconforming uses that do not occupy a structure must end within 3 years ; nonconforming uses that occupy a structure must end within 7 years from the ordinance effective date, unless extended by a conditional use permit. § 17.16.090.

Q: If I want to expand a nonconforming business, is that allowed?

Expansions are not generally allowed unless the City Council grants a Conditional Use Permit . The Council must find either an unreasonable practical difficulty or that demolition would harm a designated historic/cultural resource, and also find the expansion is not detrimental to public health, safety or nearby properties. § 17.16.120.

Q: Does a nonconforming garage that encroaches into the front yard get special treatment?

Yes — the director may allow reconstruction/modification of legal nonconforming garage roofs encroaching into the front yard in specified LMR areas (north of Lomas Santa Fe Dr. and east of I‑5) subject to conditions (RBR verification, no habitable conversion, height limits, no footprint expansion). See SBMC 17.68.030(C)(1) (minor exceptions).

Q: If a nonconforming use stops operating, can I restart it later?

No — if a nonconforming use is abandoned, discontinued or changed to a conforming use for 180 continuous days , the nonconforming use right is lost and the property must thereafter be used in conformance with current zoning. § 17.16.070(B).

Q: How does parking factor into nonconforming commercial expansions?

When a change of use requires more parking than the previous use, the full amount of required parking for the new use must be provided. An addition under 50% of existing floor area needs parking only for the added area; additions 50% or greater require parking for the expansion and elimination of existing parking deficiencies. See § 17.16.110(C) and Chapter 17.52.

Q: Do coastal bluff rules affect rebuilding a nonconforming bluff‑top house?

Yes — reconstruction above or near coastal bluffs typically requires a geologic report showing the work will not adversely affect bluff stability for 70 years , and bluff setbacks in § 17.20.030(E) apply; the City Council will scrutinize bluff reconstructions. § 17.16.080(A); § 17.20.030(E).

Q: Are residential uses in commercial zones treated differently?

Yes — legally existing residential uses and structures in commercial zones are not subject to the general termination schedule in § 17.16.090 and may continue under the chapter’s requirements; new commercial or mixed structures may be established consistent with commercial standards but the requirement for integrated mixed‑use structures may not apply to preexisting residential uses. § 17.16.110(D).

Q: Who decides whether a novel use is permitted or similar to listed uses?

The Planning Director has authority under SBMC 17.12.030 to determine whether an unlisted use is similar to those in the Use Matrix; the determination must be consistent with the general plan and zone intent. See § 17.12.030.

Overview

Solana Beach regulates nonconforming uses and structures in Chapter 17.16 of the City Zoning Ordinance. The chapter defines what qualifies as a nonconforming use or nonconforming structure, places the burden of proof on the owner to establish legal nonconformity, limits repairs/additions, sets restoration/destruction thresholds, and creates a termination schedule and a path for limited extensions or expansions by conditional use permit. See the city zoning overview and detailed zone rules for how the rules play out in each zone. § 17.16.010; § 17.16.020.

Note: This page stays strictly on zoning nonconformities (Title 17). For building-code obligations consult the California Building Standards Code / Title 24. (Verify with the jurisdiction as needed.) Solana Beach zoning & planning overview California Building Standards Code

What the ordinance requires — core rules (plain-English + code pointers)

Definition and burden of proof: A nonconforming use is a use that was lawful when established but does not now fit the zoning matrix; a nonconforming structure is a building/feature that lawfully existed but no longer meets development standards. The owner must prove the use/structure qualified as legal when created. § 17.16.020; § 17.16.030.
Maintenance allowed, expansion limited: Routine maintenance and refurbishment are permitted, but improvements cannot increase the size, degree, or intensity of the nonconformity. Additions that increase the nonconformity are prohibited unless allowed by other rules (CUP, variance). § 17.16.040; § 17.16.050; § 17.16.060.
Change of use / abandonment: A nonconforming use cannot be changed to another nonconforming use. If a nonconforming use is discontinued, abandoned, or changed to a conforming use for 180 continuous days, the right is lost. § 17.16.070.
Damage and restoration thresholds:
- Residential principal structures: May be rebuilt to the pre-existing building envelope after damage, provided reconstruction is started within 3 years and completed within 18 months from permit issuance. § 17.16.080(A).
- Nonresidential principal structures: May be restored only if the damage is 50% or less of floor area or replacement value; if >50% destroyed, rebuilt structure must conform to current code (but preexisting nonconforming use may be resumed in a rebuilt conforming structure). § 17.16.080(B).
- Accessory structures: If an accessory structure is destroyed to at least 50% of replacement value it may not be restored unless it conforms — exception: accessory structures on residential lots may be restored to their pre-existing envelope. § 17.16.080(C).
Termination schedule: All nonconforming uses (except density nonconformities) must be terminated on the schedule in Table 17.16.090: uses not occupying a structure — 3 years; uses occupying a structure — 7 years from the effective date of the ordinance, subject to extension by conditional use permit. § 17.16.090.
Extensions / expansion by Conditional Use Permit (CUP): The City Council may grant expansion, restoration, or time extensions by CUP if findings are met (hardship/unreasonable practical difficulty or protection of historic character; not detrimental to public welfare). The Council may also set a specific termination date as a condition. § 17.16.120.
Specific nonconformities: walls/fences may remain in perpetuity if not enlarged; outdoor storage must be brought into conformity within 3 years; nonconforming parking has special rules when changing uses or expanding (see SBMC 17.52 and § 17.16.110(C)). § 17.16.110.
Coastal / bluff-specific rules: Reconstruction on coastal bluffs has special geologic-report and setback conditions in the residential restoration rules and in the residential development standards (see coastal bluff setbacks). § 17.16.080(A); § 17.20.030(E).

Because zone standards affect whether a structure/use is nonconforming, review the applicable zone chapters and development standards before planning restoration, expansion, or change of use. Solana Beach Zoning Solana Beach Development Standards

District-by-district breakdown (how nonconforming rules interact with each zoning district)

Note: The nonconforming rules in Chapter 17.16 apply citywide; below we summarize each zone’s purpose and key dimensional standards that influence nonconformity status or restoration options. For full permitted-use detail see the Use Matrix (Table 17.12.020-A) and the specific zone chapters cited below. Solana Beach Land Use

ER-1 and ER-2 (Estate Residential)

Purpose: ER-1 and ER-2 are estate zones (0–2 du/acre) for semi‑rural single-family lots. § 17.20.010(A).
Typical uses: single-family dwellings, accessory structures (subject to accessory rules).
Key dimensional standards: minimum lot areas (ER-1: 40,000 sq ft; ER-2: 20,000 sq ft), setbacks determined by map designator A–D (see Table 17.20.030‑D: e.g. designator A front 35', side 15', rear 50'), maximum building height 25 ft (30 ft in MHR/HR via DRP exceptions). § 17.20.030 (Tables A, D); § 17.20.040(F, G).
Where these rules matter: restoration thresholds in § 17.16.080 reference re‑establishment of building footprint, yards, setbacks and height to the pre‑existing envelope.

LR (Low Residential)

Purpose: LR is intended for detached single-family homes on older subdivided lots. § 17.20.010(B).
Typical uses: single-family, accessory units (and now ADU path subject to state law).
Key dimensional standards: minimum lot areas (see Table 17.20.030‑A), setbacks by map designator A–D (Table 17.20.030‑D), FAR schedule and max height 25 ft. § 17.20.030.

LMR (Low-Medium Residential)

Purpose: LMR supports higher density single‑ and low‑rise multifamily (see § 17.20).
Typical uses: multifamily, duplex/two‑unit where allowed; accessory structures.
Key dimensional standards: smaller minimum lot sizes than LR per Table 17.20.030‑A; setbacks per map designator; max height 25 ft; daylight-plane guidance applies. § 17.20.030; § 17.20.040.

MR (Medium Residential), MHR (Medium‑High), HR (High Residential)

Purpose: higher density residential zones, with MR → MHR → HR progressively allowing more units per acre. § 17.20.010.
Typical uses: multifamily housing; special standards for separation between principal structures (e.g., 15 ft separation in MR/MHR/HR; 10 ft for detached single‑family units). § 17.20.030(D)(3).
Key dimensional standards: FAR caps (e.g., MHR/HR FAR .75), maximum building height 25 ft (may be increased to 30 ft via development review for MHR and HR), daylight plane guidance. § 17.20.030(F–G).

C (General Commercial), LC (Limited Commercial), OP (Office Professional), LI (Light Industrial), SC (Special Commercial)

Purpose and permitted uses: these zones house commercial, retail, office, light industrial and mixed commercial/residential uses; the Use Matrix (Table 17.12.020‑A) controls permitted/conditional/prohibited uses by zone. § 17.24 & § 17.12.020.
Key dimensional standards: commercial FARs and heights are listed in Table 17.24.030‑C/D (e.g., C FAR up to 1.2; C max height 35 ft up to 3 stories; OP and LI have taller allowances; specific exceptions west/east of Highway 101 and by area). § 17.24.030.
How nonconforming rules interact: Nonresidential restoration uses the 50% rule for destruction threshold. Expansions/changes that increase parking demand are constrained by § 17.16.110(C) and Chapter 17.52 parking rules. Solana Beach Parking

PI (Public Institutional), A (Agricultural), OSR/OSP (Open Space / Preserve), ROW (Right‑of‑Way)

Purpose and permitted uses: PI for institutional uses; A for agriculture; OSR/OSP protect open space; ROW covers public transportation corridors. See respective chapters § 17.32, § 17.36, § 17.40/17.42, § 17.44.
Key standards: ROW has specific development rules including a 10‑ft minimum setback where ROW abuts residential property and a 30‑ft maximum building height baseline for ROW. § 17.44.030.

Overlay and Special Purpose Zones (SROZ, HOZ, SAOZ, Floodplain, Scenic, etc.)

Purpose: overlay zones add site‑specific standards (e.g., scaled residential overlay SROZ, hillside overlay HOZ, scenic area overlay SAOZ). See 17.48.
How this affects nonconformities: overlay rules can supersede or add additional constraints on rebuilds, setbacks, grading, height, and DRP requirements; restoration on bluff or HOZ slopes will trigger additional geological and design requirements. § 17.48; § 17.20.030(E). Solana Beach Overlay Districts

Quick reference table — decision‑relevant nonconforming standards

Rule / Issue	Short rule	Code reference
Owner’s burden to prove legal nonconformity	Owner must document that the use/structure complied with law when created.	§ 17.16.030.
Maintenance and repairs	Routine maintenance and refurbishment allowed; no enlargement of nonconformity.	§ 17.16.040; § 17.16.060.
Change/abandonment	Abandonment/discontinuance for 180 days terminates nonconforming use.	§ 17.16.070.
Residential restoration (damage)	Restore pre‑existing envelope if reconstruction started within 3 years and finished within 18 months from permit issue.	§ 17.16.080(A).
Nonresidential restoration (damage)	If ≤ 50% destroyed may be restored to preexisting envelope; if >50% must conform (except preexisting use may be resumed).	§ 17.16.080(B).
Termination schedule	Nonconforming uses not in structures: 3 years; uses in structures: 7 years (from ordinance effective date).	§ 17.16.090.
Expansion / time extension	Expansion/restoration/time extension possible by CUP if findings met (hardship or historic preservation; not detrimental).	§ 17.16.120.
Parking when changing/expanding	If new use requires more parking, full parking required; additions <50% floor area require parking for addition only; additions ≥50% must cure existing parking deficiency.	§ 17.16.110(C); Chapter 17.52.

Checklist — what an applicant must satisfy to preserve or alter a nonconformity

Assemble documentary proof that the use/structure was legally established (permits, assessor records, dated photographs, affidavits) — owner’s burden: § 17.16.030.
Confirm whether the nonconformity is a use or a structure (definitions at § 17.16.020) and whether it involves density (different treatment). § 17.16.020.
For repairs/restoration after damage, document percentage of damage (cost or floor‑area) to determine the 50% threshold for nonresidential or the residential restoration timing rules. § 17.16.080(B).
If on a coastal bluff or canyon rim, order a geologic/soils report early — bluff reconstructions have extra findings and a 70‑year stability expectation may be required. § 17.16.080(A); § 17.20.030(E).
If proposing expansion/time extension, prepare for a Conditional Use Permit (findings of hardship vs. public harm) — City Council makes the decision and may attach a termination date. § 17.16.120.
If change of use or expansion affects parking, prepare a parking analysis and plan to meet Chapter 17.52 standards (and parking cure rules in § 17.16.110(C)). Solana Beach Parking § 17.16.110(C).
Check for overlay rules and whether Development Review or a DRP is required (HOZ, SAOZ, SROZ, floodplain). Solana Beach Design Review Solana Beach Overlay Districts § 17.48; § 17.68.040.

Risks & Ambiguities

Issue	Why it matters	What to verify
Legal vs. illegal nonconformity	Uses that required a permit but had none are illegal, not nonconforming; illegal development is handled under enforcement rules (SBMC 17.72.120).	Verify building permits, use permits, county assessor RBR and file evidence; if no permit exists, treat as illegal and contact enforcement. § 17.16.020(5); enforcement ref. SBMC 17.72.120.
Damage threshold measurement	Whether damage is counted by floor area or replacement value affects right to rebuild (especially for nonresidential).	Obtain contractor estimates and FEMA/insurance scope to document % damage; reference § 17.16.080(B).
Parking shortfalls on expansion	Expanding can trigger full cure of parking deficiencies if expansion ≥50% of floor area.	Prepare parking counts and confirm required parking per Chapter 17.52; review § 17.16.110(C). Solana Beach Parking
Coastal bluff reconstructions	Bluffs require geotechnical substantiation; city council may need to find reconstruction won’t harm bluff stability for 70 years.	Commission a geologic report from city‑approved geologists; check SBMC 17.16.080(A) and 17.20.030(E).
Mixed commercial/residential on commercial parcels	Existing residential uses in commercial zones are treated specially (they are not subject to the termination schedule).	Verify whether the residential use is legally existing and review § 17.16.110(D) and the relevant commercial-zone provisions. § 17.16.110(D).
Overlay-specific exceptions	Overlay zones (SROZ, HOZ, SAOZ, FPOZ) can change setbacks, DRP triggers and rebuild allowances.	Check overlay map/designators and the overlay chapter § 17.48 and related sections before assuming standard zone rules. Solana Beach Overlay Districts

Plain-English summary

Solana Beach treats nonconforming uses and structures as lawful survivors of older rules but limits them: you can maintain and, in most cases, repair a nonconforming building, but you generally cannot increase the nonconformity or switch to another nonconforming use; restoration after damage depends on whether the building is residential or commercial and how much was destroyed; time limits and termination schedules apply unless the city grants a conditional use permit. § 17.16.010–120.

Frequently asked questions

Can I rebuild my damaged nonconforming house in Solana Beach?

Yes — a legally existing nonconforming principal residential structure may be rebuilt to its pre‑existing building envelope if restoration is started within 3 years of damage and diligently completed within 18 months of permit issuance; restoration includes re‑establishing footprint, setbacks, height and parking that existed at the time of damage. See § 17.16.080(A).

What happens if a nonconforming commercial building is more than 50% destroyed?

If a nonconforming nonresidential principal structure is destroyed by more than 50% of floor area or replacement value it may not be rebuilt in its nonconforming form — the rebuilt structure must be brought into conformance with current zoning; however, any preexisting nonconforming use may be resumed in the rebuilt conforming structure. § 17.16.080(B).

How long can a nonconforming use continue in Solana Beach?

Nonconforming uses that do not occupy a structure must end within 3 years; nonconforming uses that occupy a structure must end within 7 years from the ordinance effective date, unless extended by a conditional use permit. § 17.16.090.

If I want to expand a nonconforming business, is that allowed?

Expansions are not generally allowed unless the City Council grants a Conditional Use Permit. The Council must find either an unreasonable practical difficulty or that demolition would harm a designated historic/cultural resource, and also find the expansion is not detrimental to public health, safety or nearby properties. § 17.16.120.

Does a nonconforming garage that encroaches into the front yard get special treatment?

Yes — the director may allow reconstruction/modification of legal nonconforming garage roofs encroaching into the front yard in specified LMR areas (north of Lomas Santa Fe Dr. and east of I‑5) subject to conditions (RBR verification, no habitable conversion, height limits, no footprint expansion). See SBMC 17.68.030(C)(1) (minor exceptions).

If a nonconforming use stops operating, can I restart it later?

No — if a nonconforming use is abandoned, discontinued or changed to a conforming use for 180 continuous days, the nonconforming use right is lost and the property must thereafter be used in conformance with current zoning. § 17.16.070(B).

How does parking factor into nonconforming commercial expansions?

When a change of use requires more parking than the previous use, the full amount of required parking for the new use must be provided. An addition under 50% of existing floor area needs parking only for the added area; additions 50% or greater require parking for the expansion and elimination of existing parking deficiencies. See § 17.16.110(C) and Chapter 17.52.

Do coastal bluff rules affect rebuilding a nonconforming bluff‑top house?

Yes — reconstruction above or near coastal bluffs typically requires a geologic report showing the work will not adversely affect bluff stability for 70 years, and bluff setbacks in § 17.20.030(E) apply; the City Council will scrutinize bluff reconstructions. § 17.16.080(A); § 17.20.030(E).

Are residential uses in commercial zones treated differently?

Yes — legally existing residential uses and structures in commercial zones are not subject to the general termination schedule in § 17.16.090 and may continue under the chapter’s requirements; new commercial or mixed structures may be established consistent with commercial standards but the requirement for integrated mixed‑use structures may not apply to preexisting residential uses. § 17.16.110(D).

Who decides whether a novel use is permitted or similar to listed uses?
