Tulelake — Nonconforming Uses
Nonconforming Uses under the Tulelake local zoning and planning code, with the controlling citations.
Last reviewed: July 3, 2026
Overview
This page explains how the City of Tulelake handles nonconforming uses, nonconforming structures, and nonconforming parcels under the City Zoning Code (Title 17). It summarizes the rights to continue, repair, modify, or rebuild uses/structures that were lawful when established but would not be allowed under current rules, and it ties those rules to the city’s zoning districts (so you can see how nonconformity interacts with local district standards). Key controlling rules are found in Chapter 17.72 of the Tulelake Zoning Code. § 17.72.010
Note: when this page refers to local development rules such as setbacks and lot coverage it links to the city’s development standards page; when it names administrative topics (e.g., parking, design review, overlays, ADUs, Title 24) the first natural mention is hyperlinked to the related Tulelake entry so you can jump to the corresponding guidance: Tulelake Development Standards, Tulelake Parking, Tulelake Design Review, Tulelake Overlay Districts, Tulelake ADUs, and the California Building Standards Code.

What the Tulelake code says (core rules)
Purpose: The City’s nonconforming chapter permits continuation of previously lawful uses/structures but limits enlargement and sets rules for repair, replacement, abandonment, and undersized parcels. § 17.72.010
Continued operation: A lawfully established nonconforming use may continue, be transferred, or be sold, but it “shall not be enlarged or intensified” beyond the area it occupied before becoming nonconforming. The person asserting the nonconforming use must present evidence the use existed prior to the ordinance change. § 17.72.020(A)
Nonconforming structures (maintenance & limited work): Nonconforming buildings may be maintained and repaired to keep them in sound condition; safety-related repairs or structural alteration to improve safety/fire hazard are expressly allowed. Routine maintenance is permitted, but full replacement is constrained. § 17.72.020(B)
Expansion / modification: Expansion or intensification of a nonconforming use is generally prohibited unless the city issues a use permit and the required findings are made (processed under the city's use-permit chapter). Additions to a nonconforming structure can be allowed only if the change does not increase the nonconformity or create new nonconformities. § 17.72.030
Destruction / rebuilding: If a nonconforming structure or a building occupied by a nonconforming use is involuntarily damaged or destroyed, it may be repaired or rebuilt and reoccupied as it originally existed provided restoration is started within two (2) years and diligently pursued. § 17.72.040
Abandonment: If a nonconforming use is discontinued for a continuous period of one (1) year or more, the nonconforming rights terminate. The code requires evidence of discontinuance and acts or failures to act showing the owner does not claim the use. Maintenance of a business license alone is not enough to show continuation. § 17.72.050
Nonconforming parcels (legal lots of record): Any lot of record on the ordinance effective date that is smaller than current district minimums may still be used as a building site provided it is not contiguous with another parcel under the same ownership; the applicant must submit a site plan and the city administrator (or city council on appeal) may approve. § 17.72.060
Nonconforming signs: Signs associated with legal nonconforming uses are treated specially; existing signs may be allowed but are subject to the sign chapter’s rules and staged removal/alteration timelines. § 17.68.090
District-by-district (how nonconforming rules work in commonly used Tulelake districts)
Below are the City districts where most nonconforming issues arise. Each subsection lists the district purpose, typical permitted uses, key dimensional standards, and where that district commonly applies. When applying the nonconforming rules above, confirm the district standards cited here (setbacks, heights, parking) because the nonconforming chapter ties repairs/alterations to conformance with other applicable provisions.
R-1 (Low Density Residential)
- Purpose: The R-1 district is for low density residential neighborhoods. § 17.16.010
- Typical permitted uses: Single‑family residential, supportive housing, transitional housing; accessory units allowed per ADU chapter. § 17.16.020
- Key dimensional standards (decision‑relevant): Minimum parcel size 6,600 sq ft, maximum building height 30 ft / 2 stories, maximum lot coverage 40%, front setback 20 ft, rear setback 20 ft, side setbacks 5 ft (interior) / 10 ft (exterior). For parking rules see the city's parking chapter. § 17.16.050–060
- Typical applications: Single-family lots and neighborhoods; many nonconforming cases arise when older houses or accessory structures predate current setbacks or lot size rules.
R-2 (Medium Density Residential)
- Purpose: The R-2 district allows a mix of low- and medium-density housing. § 17.20.010
- Typical permitted uses: Duplexes, single‑family, supportive/transitional housing. § 17.20.020
- Key dimensional standards: see Chapter 17.20 for lot size and development standards; minimums and setbacks differ from R-1 (consult § 17.20.050–060). § 17.20.050–060
- Typical applications: Denser residential conversions or multi-unit buildings where older structures may be nonconforming relative to current lot coverage, setbacks, or parking.
MU‑3 (Vertical Mixed Use — Main Street)
- Purpose: The MU‑3 district is intended for Main Street frontages with street-level commercial and residential above. § 17.36.010
- Typical permitted uses: Retail, offices, restaurants, hotels, indoor entertainment, and multiple residential types including multifamily and single-family in mixed developments. § 17.36.020
- Key dimensional standards: Maximum height 30 ft / 2 stories, lot coverage up to 100%, and minimal setbacks (often none) — these flexible standards mean some older buildings will be nonconforming in other ways (e.g., signage). § 17.36.060
- Typical applications: Historic main-street buildings, upper-floor residential conversions, and sign/ фасade work where sign chapter/nonconforming-sign rules apply. See the design review process for façade or signage changes. (/us/california/tulelake/design-review)
P‑D (Planned Development)
- Purpose: P‑D allows custom development standards for larger or master-planned sites; the city and applicant adopt site-specific standards. § 17.56.070
- Typical permitted uses & standards: Determined by the P‑D permit text — the city council sets lot sizes, setbacks, parking, and use lists at approval. § 17.56.070
- Typical applications: Subdivisions and large redevelopments; nonconforming issues are handled by referring to the approved P‑D conditions and the nonconforming chapter.
If your property sits in any other Tulelake district (for example M, MU‑1, MU‑2, P‑F, O‑S), use the district’s specific permitted uses and development standards in conjunction with the nonconforming rules above (see Chapters 17.28–17.48). Examples and full district rules are in Title 17. § 17.04.040
Quick reference table — decision‑relevant nonconforming standards and common district rules
| Issue / standard | What the code says (plain label) | Code reference |
|---|---|---|
| Can a nonconforming use continue? | Yes — may operate, be sold or transferred but may not be enlarged beyond its former area. | § 17.72.020(A) |
| Can a nonconforming structure be repaired/modified? | Routine maintenance and safety repairs allowed; structural alteration to improve safety allowed; replacement limited. | § 17.72.020(B) |
| Expansion of nonconforming use | Only with a use permit (Chapter 17.76) and required findings; expansions that increase nonconformity are prohibited. | § 17.72.030 |
| Rebuild after destruction | May rebuild/reoccupy if restoration starts within 2 years and is diligently pursued. | § 17.72.040 |
| Abandonment rule | Continuous discontinuance for 1 year terminates nonconforming rights. | § 17.72.050 |
| Legal lot of record (undersized parcel) | Existing lots of record may be used as building sites if not under same ownership as adjacent parcel; site plan required. | § 17.72.060 |
| R‑1 front setback (common) | 20 ft front setback; side/rear standards and max lot coverage 40%. | § 17.16.060 |
| MU‑3 setbacks | None in some cases (front/rear/side: none); max lot coverage 100%. | § 17.36.060 |
| Nonconforming signs | Signs for legal nonconforming uses allowed under restrictions and staged removal schedule. | § 17.68.090 |
Practical guidance — what applicants and owners must know
Evidence: To claim a nonconforming use the owner must document the prior lawful use (photos, dated business records, permits, utility bills, affidavits). § 17.72.020(A)
No enlargement without a permit: If your operation would increase its footprint, hours, customer capacity, or intensity, you generally need a use permit (Chapter 17.76). § 17.72.030
Repairs vs. replacement: Ordinary maintenance is allowed. Replacing more than the code allows or rebuilding a different form that increases nonconformity will be treated as new construction and must meet current standards. § 17.72.020(B)
Rebuilding deadlines: For involuntary destruction, begin restoration within two years or you risk losing the ability to rebuild to the previous nonconforming configuration. § 17.72.040
Undersized lots: If your lot was recorded before the ordinance and is smaller than current minimums, you can still use it as a building site — but submit a site plan and expect administrative review. § 17.72.060
Signs and fences: Nonconforming signs and fences have specific replacement/repair limits (e.g., some fences require full compliance if you replace more than 50% in a 12-month period). § 17.68.090 and § 17.80.120
Checklist
- Assemble proof that the use/structure existed as of the ordinance amendment date (photos, receipts, permits, business records). § 17.72.020(A)
- Confirm whether proposed work is maintenance, safety repair, or an enlargement (enlargement likely triggers use permit). § 17.72.020(B) and § 17.72.030
- If a parcel is undersized, prepare a site plan per § 17.80.020 and submit to the city administrator. § 17.72.060
- If the structure was destroyed, confirm start-of-restoration within 2 years and document progress. § 17.72.040
- If absent for 12 months+, prepare for the site to be required to meet full current zoning. § 17.72.050
- Check district rules (setbacks, height, lot coverage) in the applicable Chapter (e.g., 17.16, 17.20, 17.36) before proposing alterations. § 17.16.060, § 17.20.060, § 17.36.060
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Date/Proof of prior use | Nonconforming rights hinge on demonstrating the use existed before the ordinance change. | Verify what documentary evidence the city will accept; assemble dated permits, photos, utility or tax records. § 17.72.020(A) |
| Partial demolition vs. "replacement" | Repair is allowed, but replacement that materially changes the structure may lose nonconforming protections. | Confirm with City whether planned work is maintenance or constitutes replacement requiring full compliance. § 17.72.020(B) |
| Rebuilding after disaster — timing | Miss the 2‑year window and you may lose the right to rebuild the old configuration. | Document scope and start date of reconstruction; get it in writing. § 17.72.040 |
| Abandonment threshold | One year of discontinuance terminates rights — passive actions (holding a license) aren’t always enough. | Confirm continuous operation evidence the city will accept. § 17.72.050 |
| Fence/wall replacement threshold | Replacing more than 50% of a nonconforming fence/wall in 1 year triggers full compliance. | If more than 50% will be replaced, plan to bring the entire fence into compliance. § 17.80.120(M) |
| Interaction with ADU approvals | The local ADU chapter permits ADUs in districts that allow single‑family or multifamily uses, but the nonconforming chapter does not explicitly say how it affects ADU approvals. | Verify with staff whether the city will require correction of the nonconforming zoning condition as part of ADU review; the local ADU chapter is in 17.100. § 17.100.030 — For whether ADU permits can be denied based on nonconforming zoning conditions see state law (Not found in retrieved materials for a Tulelake-specific rule). |
Plain‑English summary
If your building or business in Tulelake was legal when it was built or started but doesn’t meet today’s zoning rules, you can usually keep it — you may repair it and keep operating, but you generally cannot expand it unless you secure a formal use permit; if it’s destroyed you have two years to rebuild the same way, and if you stop operating for a year you lose the nonconforming rights. § 17.72.020 — 17.72.060

Frequently asked questions
What is a legal nonconforming use in Tulelake?
A legal nonconforming use in Tulelake is a use lawfully established before the current zoning rule rendered it nonconforming; it may continue, be sold, or transferred but may not be enlarged beyond the area it lawfully occupied when it became nonconforming. § 17.72.020(A)
Can I enlarge a nonconforming business on my Tulelake property?
Not without approval: enlargement or intensification is generally prohibited unless you obtain a use permit and the city makes the required findings under the use‑permit rules. § 17.72.030
If my nonconforming building burns down, can I rebuild the same building?
Yes — if restoration/rebuilding is begun within two (2) years of the damage and is diligently pursued, you may rebuild and reoccupy in the same manner as it originally existed. § 17.72.040
What happens if I stop operating a nonconforming use for a year?
If the nonconforming use is discontinued or abandoned for one (1) year or more, the nonconforming rights terminate and any new use must comply with current zoning. § 17.72.050
My lot is smaller than the R‑1 minimum — can I build?
If the lot was on record on the ordinance effective date, it can be used as a building site even if smaller than the district minimums, provided it is not contiguous with another parcel under the same ownership and you submit an approvable site plan. § 17.72.060
Does Tulelake treat nonconforming signs differently?
Yes. Signs associated with legal nonconforming uses may remain but are subject to the sign chapter’s compliance schedule and limitations on modification or new detached signs. § 17.68.090
Will the city let me convert an old, nonconforming accessory building into an ADU?
Tulelake’s ADU chapter permits ADUs in districts that allow single‑family or multifamily uses, but the local code does not explicitly state how nonconforming zoning conditions affect ADU approvals. You must confirm with planning staff; see the ADU rules in Chapter 17.100. § 17.100.030
If I replace more than half of a nonconforming fence in one year, what happens?
If you replace more than 50% of a nonconforming fence or wall within a one‑year period, the entire fence must be brought into compliance with the code. § 17.80.120(M)
Who reviews requests to keep or modify a nonconforming lot or structure?
Administrative staff (city administrator or designee) have authority for some approvals (e.g., site plan for a nonconforming parcel); denials or unacceptable conditions may be appealed to the city council. For expansion of uses, the use‑permit process (Chapter 17.76) applies. § 17.72.060, Chapter 17.76
Do nonconforming rules differ by district (R‑1 vs. MU‑3)?
The nonconforming chapter is city‑wide, but its application depends on each district’s permitted uses and development standards (setbacks, coverage, height). For example, R‑1 has a 20‑ft front setback and 40% lot coverage while MU‑3 permits much higher lot coverage and minimal setbacks — those district rules affect whether a proposed repair or addition would increase nonconformity. § 17.16.060, § 17.36.060
