Overview

California law strongly encourages accessory dwelling unit (ADU) construction to address the housing crisis. Under Government Code Section 65852.2 and recent legislation (AB 68, SB 13), cities must approve ADU permits ministerially - meaning without discretionary review - if the project meets objective standards. Cities that wrongfully deny, delay, or impose excessive conditions on ADU permits violate state law.

Key Protection: Under Government Code 65852.2(a)(3), cities must act on ADU permit applications within 60 days. Ministerial approval means the city cannot hold discretionary hearings, impose neighborhood approval requirements, or add subjective conditions. If your ADU meets objective standards, it must be approved.

Common types of illegal ADU permit obstruction:

  • Wrongful denial: Denying permits that meet all objective standards
  • Excessive conditions: Imposing owner-occupancy, parking, or design requirements beyond state limits
  • Unreasonable delays: Failing to act within 60 days or requesting unnecessary revisions
  • Illegal fees: Charging impact fees above state caps or for units under 750 sq ft
  • Setback violations: Requiring setbacks greater than 4 feet from side and rear
  • Height restrictions: Limiting height below state minimums (16 feet or 18 feet for detached)
  • Discretionary review: Subjecting ADUs to design review, conditional use permits, or CEQA
  • Lot coverage limits: Denying based on lot coverage when ADU is 800 sq ft or less

Calculate Damages

Calculate your potential losses from wrongful permit denial:

Lost Rental Income (12 months delay) $30,000
Increased Construction Costs $15,000
Architect/Engineer Revision Fees $5,000
Carrying Costs (loan interest) $8,000
Application Fees (if excessive) $3,000
Total Damages + Attorney's Fees $61,000+
Writ of Mandamus (Primary Remedy)

The most common remedy for permit disputes:

  • Court order requiring city to approve your permit
  • City must comply with court order or face contempt
  • Relatively fast compared to other litigation
  • Can include order to process application within specific timeline
Declaratory Relief

Court declaration that city violated state law:

  • Declares local ordinance preempted by state law
  • Establishes precedent for future applications
  • Can invalidate illegal conditions or requirements
  • Helps other property owners in same jurisdiction
Attorney's Fees (Private Attorney General)

Code of Civil Procedure 1021.5 allows fee recovery:

  • Available when enforcing important public rights
  • Housing law enforcement qualifies as public interest
  • Significant benefit to public or large class of persons
  • Fees should not make action economically unfeasible

This makes it economical to pursue ADU permit litigation.

HCD Complaint and Penalties

California Housing and Community Development can:

  • Investigate complaints against non-compliant cities
  • Issue findings that local ordinances violate state law
  • Refer violations to Attorney General for enforcement
  • Cities face fines up to $100,000 per month for violations

File a complaint at hcd.ca.gov before or during litigation.

Fee Structure: I handle ADU permit disputes at $240/hr or on a partial contingency depending on the case strength. Demand letters start at $450 flat fee. The private attorney general doctrine means you may recover attorney's fees from the city if you prevail.

City Response to ADU Challenge
[City Attorney's Office] [Address] [Date] [Applicant Name] [Address] Re: Response to ADU Permit Demand Property: [Address] Application #: [Number] Dear [Applicant]: This letter responds to your demand dated [Date] regarding your ADU permit application. We have reviewed your application and the applicable law. CITY'S POSITION The City's [denial/conditions] were proper for the following reasons: 1. [State specific legal basis - e.g., "The proposed ADU does not meet the City's objective fire safety standards, which are not preempted by Government Code 65852.2."] 2. [e.g., "Your application was incomplete because it lacked [required documents], and the 60-day clock did not begin until completeness was established on [later date]."] 3. [e.g., "The proposed setback of [X] feet from the [front/street] property line does not comply with the City's objective development standards for the front yard, which are not limited by state ADU law."] APPLICABLE STANDARDS While we acknowledge the state's ADU law limits certain local requirements, Government Code 65852.2 expressly allows local agencies to impose: - Building code requirements for health and safety - Front yard setback requirements (state law limits only side and rear) - Objective design standards that do not unreasonably delay or increase cost OFFER TO MEET The City is committed to facilitating ADU development consistent with state law. We propose a meeting to: - Review the specific objections to your application - Identify modifications that would allow approval - Discuss any fee disputes Please contact [Name] at [Email] to schedule a meeting at your convenience. Sincerely, [City Attorney Name] City Attorney's Office

Next Steps

Whether your ADU permit was denied or you are a city defending your decision, here are the steps to take:

1. Document Everything

Preserve all evidence of the permit process:

  • Keep copies of your complete application and all plans
  • Save all emails and written communications with the City
  • Note dates of submissions, responses, and meetings
  • Request written confirmation of any verbal discussions
  • Photograph any posted notices or correspondence
2. Analyze City's Ordinance vs. State Law

Compare your city's ADU ordinance to state requirements:

  • Review Government Code 65852.2 carefully
  • Check HCD's ADU guidebook for interpretive guidance
  • Identify any local requirements that exceed state limits
  • Note if city ordinance was updated after 2020 reforms
  • Check if city has HCD-certified housing element
3. Send Demand Letter

A formal demand letter serves several purposes:

  • Puts city on notice of potential litigation
  • May prompt reconsideration and approval
  • Creates record for potential fee recovery
  • Send to Planning Director, City Attorney, and City Manager
4. File HCD Complaint

California HCD investigates ADU law violations:

  • File complaint at hcd.ca.gov housing portal
  • Include copies of application and city's response
  • HCD can issue findings that city violated state law
  • Findings support litigation and may prompt city action
  • HCD can refer to Attorney General for enforcement
5. File Petition for Writ of Mandamus

If the city does not resolve the dispute:

  • Superior Court: File in county where property is located
  • Mandamus: Request court order to approve permit
  • Declaratory relief: Declare local ordinance preempted
  • Attorney's fees: Request fees under CCP 1021.5
  • Timeline: Mandamus cases can be expedited
