Concord — Variances and Exceptions

Q: What is the difference between a minor exception and a variance in Concord?

A minor exception is an administrative, limited adjustment for specific items listed in Table 18.425.020 (for example small fence, setback, lot coverage, or parking tweaks) and must meet the findings in § 18.425.060 . A variance is a discretionary waiver for broader departures when special, non‑self‑created circumstances deny the property privileges enjoyed by others; variances must meet the four findings in § 18.430.060 and cannot change allowed uses, density, or FAR ( § 18.430.020 ).

Q: My lot is undersized and I need a small lot‑width reduction — should I seek a minor exception or a variance?

Check Table 18.425.020 first: some lot‑size/width reductions are allowed as a minor exception up to the table’s caps (typically 10% for lot size or width reductions). If your request exceeds those caps, prepare a variance showing the four findings in § 18.430.060 . Verify the exact numeric cap for your specific request in Table 18.425.020 .

Overview

Concord’s Development Code (commonly referred to as Title 18) provides two distinct, commonly-used ways to relax development standards: minor exceptions (an administrative, limited adjustment) and variances (a discretionary waiver when special circumstances exist). Minor exceptions are tightly delimited by Table 18.425.020 and the findings in § 18.425.060, while variances follow the criteria in § 18.430.060 and the procedural rules in § 18.430.030–070. All applications must follow the application, notice, and hearing procedures in the same chapters (applications in § 18.425.040 and § 18.430.040) and the general public‑hearing rules in § 18.500.

Notes in plain English are woven through, but every legal test below is tied to the specific Code section cited.

How Concord’s tools differ (quick synthesis)

Minor Exceptions (Chapter 18.425): short, administrative route for small, enumerated adjustments (e.g., small setback reductions, minor lot coverage or parking tweaks). Must meet the findings in § 18.425.060; larger changes require a variance.
Variances (Chapter 18.430): for situations where strict application of a development standard would deny privileges enjoyed by nearby owners because of special circumstances of the subject property. Requires the four findings in § 18.430.060 and cannot be used to allow an otherwise-prohibited use, increase density, or increase FAR.
Review authority for either can be the Planning Division (administrative decision), the Zoning Administrator (hearing), or referred to the Planning Commission—see § 18.425.030 and § 18.430.030.

I also reference Concord’s district development tables when explaining how standards vary by zone; those tables and district purposes are in Division II of the Code.

District-by-district breakdown (decision‑relevant summary)

Below are the major zoning district groups in the Concord Development Code that matter when you assess whether a variance or minor exception is needed. For each district group I summarize purpose, typical uses, key dimensional standards (high‑level), and where the district typically applies in the city. For every district name I use the Code’s designation in bold.

Note: these summaries are synthesis; always verify the specific lot’s district and the full table entries in Division II for parcel‑specific numbers. Verify with the jurisdiction.

RR, RS, RL, RM, RH (Residential districts)

Purpose: residential densities from rural/large‑lot to high‑density multifamily; rules are in Chapter 18.30.
Typical permitted uses: single‑family detached, duplexes, multifamily, home‑based businesses (permitted/conditional per Table 18.30.020).
Key dimensional standards (examples from the tables): minimum lot widths and depths, front/side/rear setbacks, buildable coverage and height vary by subzone; aggregate lot coverage caps for small‑lot subdivisions in RS/RL (see Table 18.30.030 / 18.30.040). Typical side set‑backs can be as low as 3–4 ft on one side with aggregate minimums; see CDC for exact feet.
Where applied: citywide residential neighborhoods—use the zone shown on the City zoning map (confirm with Planning).

CO, CMX, NC, RC, SC (Office & Commercial)

Purpose: office, neighborhood and community commercial, mixed‑use; see Table 18.40.030.
Typical permitted uses: offices, retail, restaurants (with restrictions), mixed‑use housing above ground floor in many CMX/CO locations.
Key dimensional standards: FARs commonly 0.35–1.0, residential height allowances ~37 ft in many mixed zones, front setbacks frequently 5–15 ft with reduced setbacks possible by permit.
Where applied: commercial corridors, shopping centers, mixed‑use nodes.

DP, DMX, WMX (Downtown / Pedestrian / Mixed‑use)

Purpose: higher‑intensity downtown core and pedestrian districts (see Table 18.45.030).
Typical uses: ground‑floor retail/restaurant required in select locations (e.g., Todos Santos Plaza), upper‑floor residential allowed.
Key dimensional standards: FAR ranges up to 4.0–6.0 depending on subdistrict, minimum FAR in some districts 0.75; lot size minima smaller than in other districts.
Where applied: downtown Concord and immediate surrounding blocks.

OBP, IBP, IMX, HI (Business Park & Industrial)

Purpose: campus‑style offices, business parks, industrial manufacturing/warehouse; see Table 18.50.030.
Typical uses: office campuses (OBP), light industrial (IBP/IMX), heavy industry (HI) with varied outdoor storage restrictions.
Key dimensional standards: FAR typically 0.6–1.0, minimum lot areas vary (10,000–40,000 sf), building heights up to 50 ft in some industrial zones; front setbacks 20–30 ft.
Where applied: North Concord, Willow Pass, business/industrial parks described in Chapter 18.50.

Planned District (PD) and Overlays

PD (Planned District): existing PDs remain; new PD development is not used normally—see § 18.25.040. Where PD records don’t exist, the code directs use of standard residential tables.
Overlays (e.g., Airport Overlay, historic): overlay rules may restrict height or require special findings; check relevant overlay chapter if your property sits inside one. For overlay rules see Division II and the overlay chapters.

Practical note: whether a variance or a minor exception is appropriate often depends on which numeric standard in the district table you'd be changing (setback, height, lot coverage, parking) and whether that change exceeds the minor exception caps in Table 18.425.020.

Decision‑relevant table (selected Code standards for exceptions/variances)

Request type	Typical maximum allowed by Minor Exception	When a Variance is required	Code reference
Fence/wall height (residential)	Up to 8 ft total	If taller than 8 ft	Table 18.425.020; § 18.425.020
Lot coverage increase	Up to 10% above code	If >10% increase	Table 18.425.020; § 18.425.020
Setback reduction (single‑family)	Front/side/rear reductions up to listed minima (front often 15 ft) or 25% rear	If reduction exceeds minor exception caps	Table 18.425.020; § 18.425.020
Structure height increase (single‑family)	Up to 10%	If >10% (multifamily/nonresidential follow § 18.150.070)	Table 18.425.020; § 18.425.020
Parking reductions (nonresidential)	Up to 10% (or limits in table)	If more reduction needed or off‑site parking/in‑lieu fee request — parking variance rules apply	Table 18.425.020; § 18.425.020, § 18.430.060(B)

How the Code tests requests (findings and limits)

Minor exceptions: approval requires the four findings listed in § 18.425.060 — (A) no practical superior alternative, (B) other Code provisions are not compromised, (C) no negative impact will result, and (D) the project complies with all applicable standards; reasonable‑accommodation requests use a different sub‑test in § 18.425.070. Decision writing and post‑decision procedures are described in § 18.425.080–090.
Variances: must meet all four findings in § 18.430.060(A): (1) strict application denies privileges enjoyed by other property owners because of special circumstances, (2) the special circumstances weren’t created by the owner/applicant, (3) the variance won’t grant special privileges inconsistent with the vicinity, and (4) the variance does not authorize a use not otherwise allowed. The Code also says variances cannot increase density, FAR, or allow uses not permitted in the zone (§ 18.430.020).
Parking variances: special test in § 18.430.060(B) that ties parking variances to incentives for nonresidential development and transit access (also referencing Gov. Code § 65906.5).
Authority and procedure: the Planning Division may grant a variance or minor exception where no hearing is requested; hearings are handled by the Zoning Administrator and appeals follow the hierarchy in § 18.400.020 and § 18.510.

(For procedural detail see § 18.425.030, § 18.425.050, § 18.430.030, and § 18.430.050.)

Checklist — what an applicant must provide

Complete application form and fees as required by the Planning Division (§ 18.425.040, § 18.430.040) — include the specific variance/minor‑exception checklist items.
Site plan, elevation drawings, and a narrative demonstrating the findings (for a variance: the four findings in § 18.430.060; for a minor exception: the four findings in § 18.425.060).
Evidence that the special circumstances are not self‑created (for variances § 18.430.060(A)(2)).
Parking analysis where parking is at issue (parking variances must meet § 18.430.060(B)). Link to the city’s parking standards for related calculations. /us/california/concord/parking
If requesting relief from setbacks, rooflines, lot coverage, or height, show the exact Code provision and the numerical amount requested and compare to the minor exception caps in Table 18.425.020 (if you exceed that table, prepare a full variance justification).
If the property is in an overlay (e.g., Airport or Historic) confirm overlay constraints and whether additional findings or limits apply; consult design standards and overlay chapters and Concord Overlay Districts.
If design quality is a factor, anticipate design review comments and possibly a PDUP (planned development use permit) if significant deviations are proposed (see PDUP procedures § 18.440). Link to Concord Design Review.

Risks & Ambiguities

Issue	Why it matters	What to verify
Is the requested change within the minor exception caps?	Minor exceptions are quicker and administrative; exceeding the caps triggers a full variance (longer, discretionary).	Check Table 18.425.020 exactly for the item and amount. Verify with Planning.
Was the “special circumstance” created by the owner?	If the applicant or owner created the condition (e.g., subdivided to make a lot small), variance findings often fail. § 18.430.060(A)(2) is explicit.	Document parcel history; provide pre‑existing condition evidence.
Does the request effectively change allowable density/FAR or permit a new use?	Variances cannot increase density or FAR or allow a use not otherwise permitted. If the change does that, the Code disallows a variance (§ 18.430.020).	Confirm whether the numeric change impacts density/FAR or use. If so, consider a rezoning/PDUP.
Is the parcel in an overlay (airport, historic)?	Overlays can impose absolute prohibitions or additional findings (e.g., height limits are tied to airport plan).	Check overlay maps and applicable overlay chapters (verify with Planning).
Does the project trigger design review or PDUP requirements?	Major design departures may trigger PDUP or design review, which require additional findings and design board input.	Confirm whether the project is in a district that requires design review or PDUP; coordinate early with planning/design review staff.
How will CEQA apply?	Some variances/minor exceptions still require environmental review if they may cause a significant environmental effect.	Ask Planning staff whether CEQA review is required for your request. § 18.405.060 (environmental review rules).

Practical guidance / plain‑English tips

If your requested change is small and matches one of the items and amounts in Table 18.425.020 (for example, a modest lot‑coverage or fence adjustment), apply for a minor exception first — it's faster and often administrative (§ 18.425.020–060).
If your need is larger, or you must change a standard beyond the minor exception caps (or you can’t show unique, non‑self‑created circumstances), prepare a full variance packet that proves the four findings in § 18.430.060.
Expect staff to compare your request to neighboring properties in the same zoning district (e.g., RM, DMX, OBP) and to evaluate whether approval would be a “special privilege” (§ 18.430.060(A)(3)).

Plain‑English Summary

A minor exception in Concord lets you request a narrowly‑defined, small adjustment to standards (fence height, small setback or coverage tweaks) and is judged under § 18.425.060; a variance is a broader discretionary waiver for properties with real, non‑self‑created hardships and must meet the four findings in § 18.430.060 — variances cannot change allowable uses, density, or FAR. For either path, follow the application and notice rules in the same chapters and confirm overlay, parking, and design‑review implications early with planning staff.

Frequently asked questions

What is the difference between a minor exception and a variance in Concord?

A minor exception is an administrative, limited adjustment for specific items listed in Table 18.425.020 (for example small fence, setback, lot coverage, or parking tweaks) and must meet the findings in § 18.425.060. A variance is a discretionary waiver for broader departures when special, non‑self‑created circumstances deny the property privileges enjoyed by others; variances must meet the four findings in § 18.430.060 and cannot change allowed uses, density, or FAR (§ 18.430.020).

Can a variance let me build more units than my zone allows?

No. The Code explicitly prohibits granting a variance to increase the maximum allowed residential density or the maximum allowed FAR. A variance cannot authorize a use not allowed in the zoning district; if you need more units you must pursue the mechanisms the Code allows (e.g., rezoning or an affordable‑housing path where applicable). § 18.430.020.

My lot is undersized and I need a small lot‑width reduction — should I seek a minor exception or a variance?

Check Table 18.425.020 first: some lot‑size/width reductions are allowed as a minor exception up to the table’s caps (typically 10% for lot size or width reductions). If your request exceeds those caps, prepare a variance showing the four findings in § 18.430.060. Verify the exact numeric cap for your specific request in Table 18.425.020.

Are parking variances treated differently in Concord?

Yes. Parking variances for nonresidential uses have a specific standard in § 18.430.060(B): they may allow off‑site parking or in‑lieu arrangements when the variance incentivizes nonresidential development and facilitates transit access, and must be consistent with Government Code requirements cited there.

Who can approve a variance or minor exception?

The Planning Division may grant either administratively when no hearing is requested; if a hearing is requested the Zoning Administrator conducts it. The Zoning Administrator may refer a request to the Planning Commission. Appeals follow the table in § 18.400.020 and the appeal procedures in Chapter 18.510.

If my property sits inside an overlay (airport or historic), can I still get a variance?

Possibly, but overlays can impose absolute or stricter constraints (e.g., height limits related to airport safety). Always check the relevant overlay chapter and discuss overlay limits with Planning staff before applying; overlay rules must be satisfied in addition to variance/minor exception findings. Not all overlay specifics are contained in the variance chapters; check the overlay chapter that applies to your parcel.

Will design review or PDUP be required if I seek a variance for setbacks or height?

If the proposed change is substantial or located in a district that requires design review or a Planned Development Use Permit (PDUP), you should expect design review and possibly PDUP findings to apply; PDUPs can be used to adjust standards for larger projects (see § 18.440). Coordinate with the design review board early.

How should I document “special circumstances” for a variance?

Demonstrate physical or site constraints (shape, topography, location, or other conditions) that predated your ownership where strict application would deny privileges others in the same zone enjoy, and show the condition was not created by the owner — this addresses § 18.430.060(A)(1)–(2). Provide historic maps, recorded subdivision documents, or other objective evidence.

If I get a minor exception approved, can neighbors appeal?

Yes. Decisions are written and subject to appeal procedures in Division VIII — the Planning Division’s decision may be appealed to the Zoning Administrator, and further to the Planning Commission and City Council per the appeal rules in § 18.510. Check the specific appeal time limits (typically 10 calendar days for many actions).

Does the Code treat reasonable accommodations (disability) differently?

Yes. Reasonable accommodation requests have a specific findings test in § 18.425.070 and are evaluated under the minor exceptions chapter where appropriate; the test focuses on necessity for housing because of disability and whether alternatives exist.
