Chapter 17.40 — VARIANCES

Hillsborough Zoning Code · 2026-07 edition · ingested 2026-07-06 · Hillsborough

17.40.010 - Permitted—When.

In cases where because of the particular size, shape, topography, location, or surroundings of any lot or parcel, or where because of the physical condition of any lot or parcel with respect to trees or natural obstacles, a strict adherence to any requirement of this title is impractical or difficult to fulfill, the requirement may be modified by the city council by granting variance.

(Ord. 639 § 21 (part), 2003)

17.40.020 - Application—Fee—Public hearing.

  • A. The property owner seeking the variance shall submit an application on the prescribed form and with the prescribed attachments to the planning office, together with the fee in the amount determined from time to time by resolution of the city council.

  • B. The variance request shall be set for public hearing before the city council.

  • C. Notice of the public hearing shall be given as set forth in Chapter 1.20 for Type A notices.

  • D. The city council shall grant the requested variance in whole or in part, conditionally or unconditionally, only if, from the facts presented with the application or established at the public hearing or determined by investigation, the city council makes both of the following findings:

    1. That because of special circumstances applicable to the property, including size, shape, topography, location, or surroundings, the strict application of the zoning ordinance deprives such property of privileges enjoyed by other property in the vicinity. (Personal, family, or financial difficulties, loss of prospective profits, and neighboring violations or neighboring preexisting nonconforming uses of facilities are not circumstances justifying a variance.)

    2. That if granted, the variance would not constitute a grant of special privileges inconsistent with the limitations upon other properties in the vicinity.

  • E. Once the city council has granted a variance, the property owner shall apply for design review approval as set forth in Chapter 2.12 and as consistent with the variance granted.

(Ord. 639 § 21 (part), 2003)

  • 17.40.030 - Deadline for use of variance—Lapse.

A variance shall be valid for so long as the requirement to which the variance applies is not amended in any way. If, however, the requirement is modified by an amendment to this code and no building permit based on the variance has been granted before the effective date of the code amendment, the variance shall lapse as of the effective date of the code amendment.

(Ord. 639 § 21 (part), 2003)

17.40.040 - Floodplain variances.

Variances involving floodplain issues shall be governed by Section 15.44.050 in addition to this chapter. In the event of a conflict, the provisions of Section 15.44.050 shall control.

Chapter 17.42 - REASONABLE ACCOMMODATION UNDER THE FAIR HOUSING ACTS

17.42.010 - Purpose.

Housing that is accessible to people with disabilities has been identified as a special housing need in the town's housing element adopted in 2002, specifically Program 4-A2. The purpose of this chapter, therefore, is to establish a formal procedure for persons with disabilities seeking equal access to housing to request reasonable accommodation under the federal Fair Housing Amendments Act of 1988 (42 USCS 3601 et seq.) and the state Fair Employment and Housing Act (California Government Code Section 12900 et seq.) ("the Acts") in the application of the town's zoning and other land use laws, regulations, rules, standards, policies, procedures, and practices (hereafter "Land Use Rules"). The further purpose of this chapter is to establish relevant criteria for considering such requests.

(Ord. 648 § 10, 2003)

17.42.020 - Applicability.

A person with a disability (meaning a person with a "disability" as defined under the state Fair Employment and Housing Act or a person with a "handicap" as defined under the federal Fair Housing Amendments Act of 1988), that person's representative, or any entity may request reasonable accommodation when the application of a Land Use Rule acts as a barrier to fair housing opportunities. A request for reasonable accommodation may include a request for modification or exception to the Land Use Rules for the siting, development, and use of housing or housing-related facilities that would eliminate regulatory barriers and provide a person with a disability equal opportunity to housing of that person's choice.

(Ord. 648 § 10, 2003)

17.42.030 - Letter of request.

  • A. Requests for reasonable accommodation shall be submitted by letter to the city planner and shall describe the requested accommodation and contain the following information:

    - (1) Name, address, and telephone number of the person or entity making the request. 
    
    - (2) Address of the property for which the request is being made. 
    
    - (3) Current actual use of the property. 
    
    - (4) Basis for the claim that the individual is a person with a disability under the Acts. 
    
    - (5) Land Use Rule regarding which reasonable accommodation is being requested. 
    
    • B. No fee shall be required for submitting a letter of request under this chapter or filing an appeal under Section 17.42.050.
  • (Ord. 648 § 10, 2003)

17.42.040 - Review and decision.

  • A. The city planner shall review the request and make a written determination within forty-five days after receipt of the request. The written determination shall be consistent with the requirements of the Acts and shall at a minimum address the factors set forth in paragraph C below.

  • B. The city planner may grant, grant with modifications, or deny the request. In granting the request or granting the request with modifications, the city planner may impose any conditions of approval that the city planner deems reasonable and necessary to ensure that the reasonable accommodation is consistent with the factors set forth in subsection (C) below.

  • C. The city planner's decision shall be based on consideration of the following factors:

    • (1) Whether the housing that is the subject of the request will be used by an individual with a disability under the Acts.

    • (2) Whether the requested reasonable accommodation is necessary to make specific housing available to an individual with a disability under the Acts.

    • (3) Whether the requested reasonable accommodation would impose an undue financial or administrative burden on the town.

    • (4) Whether the requested reasonable accommodation would require a fundamental alteration in the nature of a town program or law, including, but not limited to, land use and zoning.

    • (5) The physical attributes of the property and the structures on the property.

    • (6) The potential impact of the requested reasonable accommodation on surrounding properties.

    • (7) Alternative reasonable accommodation on the property.

(Ord. 648 § 10, 2003)

17.42.050 - Appeal.

The person or entity that requested the reasonable accommodation may appeal the city planner's denial of the request or may appeal the conditions or modifications imposed by the city planner on the grant of the request. The appeal shall be submitted to the city planner in writing within fifteen days after the date of the city planner's decision. The appeal shall be heard by the city council in a public hearing noticed pursuant to Chapter 1.20 using a type B public notice.

(Ord. 648 § 10, 2003)

17.42.060 - Effect of chapter.

This chapter shall be interpreted and applied in accordance with the Acts; nothing in this chapter shall be deemed to create greater rights than exist under the Acts.

  5. Septic System. If the ADU or JADU will connect to an onsite wastewater-treatment system, the owner must include with the application a percolation test completed within the last five years or, if the percolation test has been recertified, within the last ten years.

  6. Owner Occupancy.

    • a. ADUs. ADUs are not subject to an owner-occupancy requirement.

    • b. JADUs.

      • (1) Generally. As required by state law, JADUs are generally subject to an owneroccupancy requirement. A natural person with legal or equitable title to the property must reside on the property, in either the primary dwelling or JADU, as the person's legal domicile and permanent residence.

      • (2) Exceptions. The owner-occupancy requirement in this subsection E.7.b. does not apply in either of the following situations:

        • i. The JADU has separate sanitation facilities (i.e. does not share sanitation facilities with the existing primary dwelling unit structure).

        • ii. The property is entirely owned by another governmental agency, land trust, or housing organization.

  7. JADU Deed Restriction. Prior to issuance of a certificate of occupancy for a JADU, a deed restriction must be recorded against the title of the property in the county recorder's office and a copy filed with the building and planning department. The deed restriction must run with the land and bind all future owners. The form of the deed restriction will be provided by the town and must provide that:

    • a. The JADU may not be sold separately from the primary dwelling.

    • b. The JADU is restricted to the approved size and to other attributes allowed by this section.

    • c. The deed restriction runs with the land and may be enforced against future property owners.

d.

The deed restriction may be removed if the owner eliminates the JADU, as evidenced by, for example, removal of the kitchen facilities. To remove the deed restriction, an owner may make a written request of the building and planning department, providing evidence that the JADU has in fact been eliminated. The building and planning department may then determine whether the evidence supports the claim that the JADU has been eliminated. Appeal may be taken from the building and planning department's determination consistent with the other provisions of this code. If the JADU is not entirely physically removed, but is only eliminated by virtue of having a necessary component of an JADU removed, the remaining structure and improvements must otherwise comply with applicable provisions of this code.

  • e. The deed restriction is enforceable by the director of building and planning or his or her designee for the benefit of the town. Failure of the property owner to comply with the deed restriction may result in legal action against the property owner, and the town is authorized to obtain any remedy available to it at law or equity, including, but not limited to, obtaining an injunction enjoining the use of the JADU in violation of the recorded restrictions or abatement of the illegal unit.

signee for the benefit of the town. Failure of the property owner to comply with the deed restriction may result in legal action against the property owner, and the town is authorized to obtain any remedy available to it at law or equity, including, but not limited to, obtaining an injunction enjoining the use of the JADU in violation of the recorded restrictions or abatement of the illegal unit.

  1. Rent Reporting. In order to facilitate the town's obligation to identify adequate sites for housing in accordance with Government Code Sections 65583.1 and 66330, the following requirements must be satisfied:

    • a. With the building permit application, the applicant must provide the town with an estimate of the projected annualized rent that will be charged for the ADU or JADU.

    • b. Within ninety days after each January 1 following issuance of the building permit, the owner must report the actual rent charged for the ADU or JADU during the prior year. If the town does not receive the report within the ninety-day period, the owner is in violation of this code, and the town may send the owner a notice of violation and allow the owner another thirty days to submit the report. If the owner fails to submit the report within the thirty-day period, the town may enforce this provision in accordance with applicable law.

    • c. This requirement shall not be the basis for the delay or denial of an ADU application.

  2. Building and Safety.

  • a. Must Comply with Building Code. Subject to subsection E.9.b. below, all ADUs and JADUs must comply with all local building and fire code requirements.

  • b. No Change of Occupancy. Construction of an ADU does not constitute a group R occupancy change under the local building code, as described in Section 310 of the California Building Code, unless the building official makes a written finding based on substantial evidence in the record that the construction of the ADU could have a specific, adverse impact on public health and safety. Nothing in this subsection E.10.b. prevents

the town from changing the occupancy code of a space that was uninhabitable space or that was only permitted for nonresidential use and was subsequently converted for residential use in accordance with this section.

  1. Structures and Equipment within Setbacks. No structures or mechanical equipment may be located within the ADU setback area.

  2. Certificate of Occupancy Timing.

  - a. Generally. No certificate of occupancy for an ADU or JADU may be issued before the certificate of occupancy is issued for the primary dwelling unit. 

  - b. Limited Exception for State-declared Emergencies. Notwithstanding subsection a above, a certificate of occupancy for an ADU may be issued before a certificate of occupancy for the primary dwelling if each of the following requirements are met: 

     - (1) The county is subject to a proclamation of a state of emergency made by the California Governor on or after February 1, 2025. 

     - (2) The primary dwelling was substantially damaged or destroyed by an event referenced in the Governor's state of emergency proclamation.
  • (3) The ADU has been issued construction permits and has passed all required inspections.

       - (4) The ADU is not attached to the primary dwelling. 
    
    - c. Local Exception for detached ADUs. Notwithstanding subsection E.12.a. above, a sixmonth temporary certificate of occupancy for a detached ADU may be issued before a certificate of occupancy for the primary dwelling if each of the following requirements are met: 
    
       - (1) The ADU has been issued construction permits and has passed all required inspections. 
    
       - (2) The ADU is not attached to the primary dwelling. 
    
  • F. Class 2 ADU Requirements. The following requirements apply only to class 2 ADUs approved under subsection D.2. above. This subsection F. does not apply to class 1 ADUs or JADUs approved under subsection D.1. above.

    • b. An attached ADU that is created on a lot with an existing primary dwelling is further limited to fifty percent of the floor area of the existing primary dwelling.

    • c. Application of other development standards in this subsection F., such as FAR or lot coverage, might further limit the size of the ADU, but no application of the percent-based size limit in subsection F.1.b. above or of an FAR, front setback, lot coverage limit, or openspace requirement may require the ADU have less than eight hundred square feet of interior livable space.

  1. Setbacks.

    • a. Side and Rear. ADUs that are subject to this subsection F. must conform to four-foot side and rear setbacks.

    • b. Front. ADUs that are subject to this subsection F. must conform to twenty-foot front setbacks, notwithstanding subsection F.1.c. above.

    • c. No setback is required for an ADU that is subject to this subsection F. if the ADU is constructed in the same location and to the same dimensions as an existing structure.

  2. Lot Coverage. Notwithstanding subsection F.1.c. above, no ADU subject to this subsection F. may cause the total lot coverage of the lot to exceed 50 percent, or to exceed 40 percent in any setback area adjacent to a street line. Lot coverage is calculated in square feet as the sum of all hardscape coverage and structural coverage of a lot. Structural coverage and hardscape coverage are defined and calculated as follows:

    • a. Structural Coverage. Areas of a lot located beneath a structure having a roof and two or more walls, for example a dwelling, a pool house, or a garage. Structural coverage calculations and maximums are outlined as follows:

  • G. Impact Fees. The following requirements apply to all class 1 ADUs and JADUs and class 2 ADUs.

    1. School Fees. A JADU or ADU with less than five hundred square feet of interior livable space does not increase assessable space by five hundred square feet for the purposes of Education Code Section 17620(a)(1)(c) and is therefore not subject to school fees under Education Code Section 17620.

    2. Other Development Impact Fees.

      • a. No impact fee is required for a JADU or for an ADU that is less than seven hundred fifty square feet of interior livable space.

      • b. Any impact fee that is required for an ADU that is seven hundred fifty square feet or more of interior livable space must be charged proportionately in relation to the square footage of the primary dwelling unit (e.g. the floor area of the ADU, divided by the floor area of the primary dwelling, times the typical fee amount charged for a new dwelling).

  • H. Nonconforming Zoning Code Conditions, Building Code Violations, and Unpermitted Structures.

    1. Generally. The town will not deny an ADU or JADU application due to a nonconforming zoning condition, building code violation, or unpermitted structure on the lot that does not present a threat to the public health and safety and that is not affected by the construction of the ADU or JADU.

    2. Unpermitted ADUs and JADUs Constructed Before 2020.

      • a. Permit to Legalize. As required by state law, the town may not deny a permit to legalize an existing but unpermitted ADU or JADU that was constructed before January 1, 2020, unless denial is based on either of the following grounds:

        • (2) The ADU or JADU does not comply with state ADU or JADU law or this ADU ordinance (Chapter 17.52).

      • b. Exceptions.

        • (1) Notwithstanding subsection H.2.a. above, the town may deny a permit to legalize an existing but unpermitted ADU or JADU that was constructed before January 1, 2020, if the town makes a finding that correcting a violation is necessary to comply with the standards specified in California Health and Safety Code Section 17920.3.
  • (2) Subsection H.2.a. above does not apply to a building that is deemed to be substandard in accordance with California Health and Safety Code Section 17920.3.

    1. Encouragement of ADU Establishment in Existing Residential Livable Spaces and Domestic Units. Recognizing that there may be a considerable existing stock of potential ADUs in the town representing a valuable housing resource for the community, including guest suites, guest quarters, pool houses, carriage houses, domestic quarters, and similar spaces, the town encourages property owners to apply to establish an ADU or JADU within existing space in accordance with this chapter.

      • a. No Penalty for Seeking Legalization. Upon receipt of an application to legalize an unpermitted ADU or JADU described in subsection H., the town shall not penalize the applicant solely for having established the unpermitted or nonconforming unit.

      • b. Existing Detached Domestic Units—Legal Nonconforming Status.

        • (1) A detached domestic unit that was lawfully established and existing as of January 10, 1983, is deemed a legal nonconforming accessory structure.
      • (2) Detached domestic unit means living quarters designed, capable of being used, or intended to be used to house household help, such quarters being not structurally attached to the single-family dwelling served by the household help.

      • (3) Except as provided in subsection H.3.c. below, alterations to a legal nonconforming detached domestic unit that is not being permitted as an ADU shall be confined to the interior of the structure; exterior improvements shall be limited to normal upkeep and repair and to improvements that do not enlarge or alter the existing exterior dimensions of the structure.

    • c. Establishing an ADU Within Existing Residential Livable Space or an Existing Accessory Structure.

      • (1) An applicant may apply to permit and legalize an ADU or JADU within existing space of a primary dwelling or within an existing accessory structure, including an existing detached domestic unit.

      • (2) When an existing detached domestic unit or other existing space is proposed to be established as an ADU, the town shall not require correction of unrelated nonconforming zoning conditions, building code violations, or unpermitted structures found elsewhere on the lot that are not impacted by the ADU and do not pose a threat to public health and safety.

      • (3) Improvements to an existing structure in connection with establishing an ADU may include those alterations necessary to comply with applicable building standards and this chapter. Any expansion beyond the existing structure shall be regulated by Chapter 17.52 and applicable state law.

  • d. Disaster Reconstruction. If a natural disaster (such as a fire, earthquake, flood, landslide, etc.) damages or destroys an existing detached domestic unit or other existing accessory structure that is proposed to be established as an ADU, the structure may be reconstructed in the same location and to the same or smaller exterior dimensions as the damaged or destroyed structure, consistent with this chapter and applicable state law.

  2. Lot Coverage. The lots that result from an urban lot split under this chapter must comply with the lot-coverage regulations imposed through the underlying zone, except that the lot-coverage standards are only enforced to the that they do not prevent two primary dwelling units on the lot at eight hundred square feet each.

  3. Setbacks.

    • a. Generally. All setbacks must conform to those objective setbacks that are imposed through the underlying zone.

    • b. Exceptions. Notwithstanding subpart F6a above:

    3. All fee interest in the lot and all the dwellings must be held equally and undivided by all individual property owners.

    4. No timeshare, as defined by state law or this code, is permitted. This includes any coownership arrangement that gives an owner the right to exclusive use of the property for a defined period or periods of time.

  • I. Regulation of Uses.

      • b. The anticipated start and end dates for construction;

      • c. The hours of construction;

      • d. Contact information for the project manager (for construction-related complaints); and

      • e. Contact information for the building and safety department.

  1. This notice requirement does not confer a right on the noticed persons or on anyone else to comment on the project before permits are issued. Approval is ministerial. Under state law, the town has no discretion in approving or denying a particular project under this chapter. This notice requirement is purely to promote neighborhood awareness and expectation.
  • K. Deed Restriction. The owner must record a deed restriction, on a form approved by the town, that does each of the following:

    1. Expressly prohibits any rental of any dwelling on the property for a period of less than thirty days.

    4. If the lot is not created by an urban lot split: expressly requires the individual property owners to live in one of the dwelling units on the lot as the owners' primary residence and legal domicile.

    5. If the lot is created by an urban lot split: States that the property is formed by an urban lot split and is therefore subject to the town's urban lot split regulations, including all applicable limits on dwelling size and development.

    6. States that development on the lot is limited to development of residential units under Chapter 17.54 of this code, except as required by state law.

  • L. Specific Adverse Impacts.

    1. Notwithstanding anything else in this chapter, the town may deny an application for a two-unit project if the building official makes a written finding, based on a preponderance of the evidence, that the project would have a "specific, adverse impact" on either public health and safety or on the physical environment and for which there is no feasible method to satisfactorily mitigate or avoid the specific adverse impact.

    2. "Specific adverse impact" has the same meaning as in Gov. Code Section 65589.5(d)(2): "a significant, quantifiable, direct, and unavoidable impact, based on objective, identified written public health or safety standards, policies, or conditions as they existed on the date the application was deemed complete" and does not include:

      • a. Inconsistency with the zoning ordinance or general plan land use designation; or

      • b. The eligibility to claim a welfare exemption under Revenue and Taxation Code Section 214(g).

    3. The building official may consult with and be assisted by planning staff and others as necessary in making a finding of specific, adverse impact.

  • M. Remedies. If a two-unit project violates any part of this code or any other legal requirement:

    1. The buyer, grantee, or lessee of any part of the property has an action for damages or to void the deed, sale, or contract.
