Waterford — Nonconforming Uses

Q: If my nonconforming house is damaged in a fire, can I rebuild?

If the nonconforming structure is more than 50% damaged, it cannot be re‑established except by meeting the current district rules; this is in § 17.63.050 — coordinate with Building and Planning to confirm rebuild options and any required permits .

Q: How long can a nonconforming use sit inactive before I lose the right to resume it?

If a nonconforming use ceases for six months continuously it is considered abandoned and any future use must comply with the district regulations — § 17.63.050 .

Overview

This page explains how the City of Waterford treats nonconforming uses, nonconforming structures, and related nonconforming lots under the Waterford Zoning Ordinance (Title 17). It summarizes the rules that control continuance, repair, enlargement, abandonment, and discretionary relief — and ties those rules to the city’s zoning districts so you can see how district-specific standards interact with nonconforming status. For general context see the city’s Waterford Zoning materials.

Key takeaways up front: Waterford allows lawful pre‑existing uses and structures to continue, but limits increases, requires permits for most changes/expansions, treats long inactivity and substantial damage as termination events, and gives the Planning Commission discretion to authorize exceptions when strict application would injure property rights. See the controlling local rules at § 17.63.010–.080 .

What the code defines and requires (core rules)

Definitions: "Nonconforming uses" and "Nonconforming structure" are defined in the ordinance definitions chapter (Chapter 17.02; see § 17.02.030) — these are a use or structure lawfully established that no longer conform because of a later change to the zoning code or annexation .
Continuance: A lawful nonconforming use or structure may be continued but may not be enlarged, increased, or extended to occupy more area than existed when it became nonconforming; it may not create a public health or safety hazard (see § 17.63.020) .
Extension / Change: Extending a nonconforming use within a building or changing it to a more restrictive use requires a use permit (§ 17.63.030, § 17.63.040) .
Abandonment and damage: If a nonconforming use ceases for six months it is considered abandoned and may not resume except in conformity with the current district rules; if a nonconforming structure is more than 50% damaged it cannot be re-established except under current district provisions (§ 17.63.050) .
Maintenance & repair: Ordinary maintenance is allowed provided no structural alteration is made and work does not exceed 15% of appraised value in any one year; other repairs/alterations require a use permit (§ 17.63.060) .
Enlargement / restoration by exception: The Planning Commission can authorize change, enlargement, expansion or restoration after a public hearing if specific findings are met (preserve property rights, not detrimental to health/safety/welfare, not injurious to neighborhood) and may attach conditions (§ 17.63.070) .
Residential minor expansion: A legal nonconforming single‑family dwelling or duplex may be expanded by up to 25% of existing floor area with Planning Director approval, provided code requirements are otherwise met and no additional units are created (§ 17.63.080) .
Nonconforming parking: Existing uses are not made nonconforming solely by lack of off‑street parking; parking being used at date of ordinance adoption cannot be reduced below that level (§ 17.54.020) .

A compact decision table with the most‑applied rules appears below.

Rule / Action	What the code allows or prohibits	Code reference

Extend within a building	Allowed only with a use permit	§ 17.63.030
Change to more restrictive use	Allowed only with a use permit	§ 17.63.040
Abandonment/cessation	6 months continuous cessation → considered abandoned	§ 17.63.050
Substantial damage	> 50% destroyed → cannot re‑establish except under current district rules	§ 17.63.050
Maintenance threshold	Ordinary maintenance allowed if ≤ 15% appraised value/year; otherwise use permit	§ 17.63.060
Planning Commission exception	May authorize enlargements/restorations after hearing if findings met	§ 17.63.070

Parking	Existing parking cannot be reduced below what was in place on adoption date	§ 17.54.020

District-by-district practical guide

Waterford’s zoning districts each contain their own permitted uses and development schedules; the nonconforming rules of Chapter 17.63 apply to all districts (see § 17.63.010) . Below are the principal districts most likely to raise nonconforming questions; each subsection lists the district purpose, typical permitted uses, representative dimensional standards, where the district text points you for nonconforming rules, and the local code citation.

NOTE: Each district heading below is the code-designated district name (bolded) and uses the district-specific development/regulation sections of Title 17.

RS, RM, RH (Residential districts)

Purpose: Low‑ to high‑density residential uses, with standards tuned to single‑family, multifamily and higher intensity housing respectively. See the RS/RM/RH development schedule and supplemental rules in § 17.20.050 and related subsections .
Typical permitted uses: Single‑family homes, multifamily (varies by district), accessory dwelling units (subject to the ADU chapter), home occupations; special uses by permit (see use tables) § 17.20.040–.050 .
Key dimensional standards (examples): Minimum lot area and widths, front/side/rear yards, maximum height (see Schedule 20‑2 in § 17.20.050) — e.g., front yard 15 ft. in many R districts; max height 35 ft. for RS/RM, 45 ft. for RH (see table) .
Where it applies / nonconforming note: All R‑district nonconforming buildings/uses are governed by Chapter 17.63; residential units established before June 1, 2011 are explicitly allowed to continue subject to Chapter 17.63 rules (see district notes) .

When you reference development limits during a nonconforming review in an R district, also consult the city’s Waterford Development Standards and the ADU rules at Waterford ADUs.

RE (Residential Estates)

Purpose: Larger estate/residential lots (minimum 3 acres) for estate‑scale housing and agricultural buffer uses § 17.10.050 .
Typical uses: Single‑family residence, limited accessory agricultural uses, bed & breakfast only on larger parcels (subject to Chapter 17.64) (see Schedule 10‑1) .
Dimensional standards: Minimum site area 3 acres, accessory building heights up to 45 ft., yards vary (see Schedule 10‑2) § 17.10.050 .
Nonconforming note: Chapter 17.63 applies; site‑specific questions about substandard lots are tied to § 17.40.090 (see referrals in the RE chapter) — verify with Planning for substandard‑lot history and applicability .

AG (Agricultural)

Purpose: Protect interim or long‑term agricultural uses and buffer adjacent residential areas § 17.08.010–.020 .
Typical uses: Crop production, horticulture, limited agricultural processing (per Schedule 08‑1) § 17.08.030 .
Dimensional standards / rules: See Schedule 08‑1 and special limitations; nonconforming agricultural uses are still governed by Chapter 17.63 .

CC, CH, CG, CR (Commercial districts)

Purpose: Local commercial, highway commercial, general commercial and regional commercial uses; each has its own use table and limits § 17.24.030–.040 .
Typical permitted uses: Retail, offices, restaurants (with special rules), live/work or multifamily in some sub‑zones (Schedule 24‑1) .
Dimensional standards: Vary by subdistrict; see Schedule 24‑1 and the “additional regulations” in § 17.24.040 for frontage/setback/height specifics .
Nonconforming note: Chapter 17.63 applies; nonconforming signs have a separate definition and are covered by sign regulations (see Chapter 17.60 and the definition in § 17.02.030) .

PS (Public and Semipublic)

Purpose: Siting large public/quasi‑public uses under tailored regulations; subdivision and parcel standards set here § 17.18.010–.040 .
Typical uses: Parks, government facilities, utilities, public safety facilities (use table Schedule 18‑1) § 17.18.020 .
Dimensional: Minimum site area typically 3 acres for certain uses; heights and yards vary (see Schedule 18‑2) § 17.18.040 .
Nonconforming note: PS district text expressly refers to Chapter 17.63 for treatment of pre‑existing nonconforming uses/structures .

OS (Open Space)

Purpose: Preserve open space resources; limited development allowed by plan § 17.14.010–.050 .
Typical uses: Parks, recreation, utilities (minor), limited residential by special condition (Schedule 14‑1) .
Nonconforming note: Chapter 17.63 is cross‑referenced for nonconforming treatment in OS § 17.14.040 .

IL, IG, IP (Industrial districts)

Purpose: Light, general and planned industrial uses; each has specific use and development standards § 17.26.040–.060 .
Typical uses: Manufacturing, warehousing, distribution, limited commercial support uses — many industrial uses are allowed subject to use permits or administrative review (Schedule 26‑1 / 26‑2) .
Dimensional examples: Minimum lot area varies (e.g., IL 10,000 sq.ft., IG/IP 20,000 sq.ft.), maximum heights can be 50 ft., coverage and FAR set by schedule § 17.26.050 .
Nonconforming note: Chapter 17.63 applies; industrial districts include cross‑references to development on substandard lots and nonconforming uses § 17.26.040–.050 .

Practical district tip: District tables frequently include a “Nonconforming uses & structures — See Ch. 17.63” note. Always pull the district schedule and the Chapter 17.63 language together when assessing a property. For parking impacts on nonconforming uses consult the city’s Waterford Parking rules and § 17.54.020 .

Checklist — What an applicant must satisfy to change, expand, or reestablish a nonconforming use or structure

Confirm the use/structure was lawfully established and determine the nonconforming trigger date (when it became nonconforming) — see definitions in § 17.02.030 .
If the proposal is an extension through a building or a change, file for a use permit as required by § 17.63.030 / § 17.63.040 and the procedures in Chapters 17.73/17.75 (uses and administrative procedures) .
If proposing ordinary repairs: document that work is maintenance only and will not exceed 15% of appraised value in a year; otherwise include a use permit application (§ 17.63.060) .
If proposing a residential addition: calculate whether the expansion is ≤ 25% of existing floor area and prepare a Planning Director application if eligible (§ 17.63.080) .
If the use has been inactive, verify continuous operation; > 6 months of continuous cessation means abandonment and re‑use will need to comply with current district rules (§ 17.63.050) .
If the structure has been > 50% damaged, obtain confirmation from Building & Planning that re‑establishment is permitted only under current district standards (§ 17.63.050) .
For enlargements beyond what Chapter 17.63 allows, prepare findings and materials for a Planning Commission hearing (see § 17.63.070) .
Check off‑street parking impacts and historic parking levels; do not reduce parking below the number in use on the ordinance adoption date (§ 17.54.020) .
Confirm compliance with all other applicable site standards (setbacks, height, landscaping, signage) in the district schedule (e.g., § 17.20.050, § 17.18.040, § 17.26.050, etc.) .

Risks & Ambiguities

Issue	Why it matters	What to verify
Is my use or building actually “nonconforming”?	Mis‑classification can lead to denial of changes or enforcement actions	Confirm historical permits/records and the date it became nonconforming with Planning; see definitions § 17.02.030
Has the use been “abandoned”?	6 months continuous cessation converts the site to conforming‑only uses; reinstatement blocked (§ 17.63.050)	Document continuous operation (receipts, leases, utility records). If uncertain, verify with Planning — § 17.63.050
Substantial damage after disaster	If > 50% damage, re‑establishment is limited to current district rules — may require full compliance	Obtain building valuation and damage assessment; confirm via Building Official and § 17.63.050
Repairs vs. alterations	Exceeding 15% appraised value in a year triggers permit requirement	Get an appraised value estimate before work; see § 17.63.060
Expansion requests	Planning Commission can approve exceptions but must make findings — discretionary and uncertain (§ 17.63.070)	Prepare thorough findings, neighborhood impact analysis, and be ready for conditions of approval
Parking shortfall	Reducing historically provided parking can create a new code violation	Check off‑street parking records and § 17.54.020; consult the Waterford Parking rules
ADUs on nonconforming lots/structures	State ADU law affects ADUs — local code interaction unclear in Title 17	Not found in retrieved materials for a specific nonconforming‑ADU rule in Waterford; Verify with Planning and see Waterford ADUs and state guidance

Plain-English summary

If your property or business in Waterford was legal when established but now conflicts with the zoning rules, you can generally keep using it — but you cannot make it larger or more intense without approval. Small repairs are allowed up to modest cost limits, temporary inactivity of six months can cancel the nonconforming right, and the Planning Commission can grant limited exceptions if strict enforcement would take away valid property rights (§ 17.63.010–.080) .

Frequently asked questions

What makes a use "nonconforming" in Waterford?

A use is nonconforming if it was lawfully established but no longer complies with the current use rules for the zoning district because of a later code change or annexation; see the ordinance definitions in § 17.02.030 and the nonconforming chapter § 17.63.010 .

Can I expand a nonconforming business or garage on my property?

Not as a matter of right. Continuation is allowed but enlargement or extension beyond the area occupied when the use became nonconforming is prohibited unless you obtain a use permit (or the Planning Commission grants an exception under § 17.63.070) — see § 17.63.020–.030 .

If my nonconforming house is damaged in a fire, can I rebuild?

If the nonconforming structure is more than 50% damaged, it cannot be re‑established except by meeting the current district rules; this is in § 17.63.050 — coordinate with Building and Planning to confirm rebuild options and any required permits .

How long can a nonconforming use sit inactive before I lose the right to resume it?

If a nonconforming use ceases for six months continuously it is considered abandoned and any future use must comply with the district regulations — § 17.63.050 .

May I do ordinary maintenance on a nonconforming building?

Yes — ordinary maintenance and repairs are allowed provided they do not involve structural alteration and do not exceed 15% of the appraised value in any one year; other repairs or alterations require approval via a use permit (§ 17.63.060) .

Can the Planning Commission allow a larger restoration or expansion?

Yes. The Planning Commission, after a public hearing, may authorize change, enlargement, expansion or restoration if it finds the action preserves substantial property rights and will not harm neighborhood health, safety or welfare; it may attach conditions (§ 17.63.070) .

If my property's parking is short of current code, does that automatically make my use nonconforming?

No. The code specifically says an existing use is not nonconforming solely because it lacks off‑street parking; however, you cannot reduce parking that existed on adoption date below the number in use at that time (§ 17.54.020) .

Where do I find the dimensional standards to check whether a structure is nonconforming for setbacks or height?

Consult the district development schedule for your zoning district (for example RS/RM/RH schedules in § 17.20.050, PS in § 17.18.040, RE in § 17.10.050, IL/IG/IP in § 17.26.050) and then apply Chapter 17.63 rules for nonconformance § 17.63.010–.080 .

Can a pre‑existing RS or RM residential unit created before 2011 continue to be used?

Yes — the code allows RS and RM residential uses established prior to June 1, 2011 to continue under Chapter 17.63 treatment (see district cross‑reference) — see district notes and § 17.63 .
