Apple Valley lets you look up the zoning on any parcel through its online Data Hub, and state law sets a floor for accessory dwelling units (ADUs) that every California town must respect. This guide explains how to check your zone, what state ADU law guarantees, how an ADU gets permitted in Apple Valley and what extra units mean when you sell.

How to find your zone

The town’s Data Hub offers a zoning lookup by address, assessor parcel number or by clicking a location within the town.

Start there before you plan any new structure, because the zone decides what you can build, how large it can be and how far it must sit from the property lines.

The Permit Center also lists zoning verification as part of its review, so staff will check your plans against the zone when you apply. For questions about a specific lot, call Planning at (760) 240-7000, extension 7100.

What state law guarantees for ADUs

The California Department of Housing and Community Development (HCD) publishes an ADU Handbook, updated March 2026.

According to the handbook, limits on lot coverage or floor area ratio cannot prevent an ADU of at least 800 square feet of interior living space that keeps four-foot side and rear setbacks, and a junior ADU (JADU) is limited to 500 square feet of interior living space and sits inside the existing single-family home.

State law requires cities to review ADU applications by objective standards.

Apple Valley’s own development code adds local rules on top, so read the current code on Municode or ask Planning before you design, because we could not confirm local ADU size and height numbers from the town’s pages.

Permitting an ADU or conversion

An ADU needs building permits in addition to any planning approval. The town’s Permit Center handles building, electrical, plumbing and mechanical permits, plan review for code compliance, accessibility, zoning and fire safety, and the foundation, framing and final inspections.

See our Apple Valley building permits guide for the full process and the town’s adopted fees. A garage conversion, a room addition or a new detached unit all go through this same permit path.

Fees to expect

The town’s Municipal Fee Schedule adopted September 26, 2023 does not list a separate ADU category in the pages we reviewed. Residential permit fees for Group R and U buildings scale with floor area, and building plan review is 90 percent of the permit fee. Planning plan check is 15 percent of building and grading permit fees. Ask the Permit Center for an estimate before you commit to a project.

What zoning and ADU rules mean when you sell

Lenders and appraisers want to know whether extra living space was legally created. A converted garage, a rear unit with a kitchen or an enclosed patio with no permit can lower an appraisal and complicate financing, and sellers must disclose known unpermitted work. Our statewide guide to selling as-is with unpermitted work explains the disclosure rules, and the tenant-occupied sale guide helps if someone lives in the extra unit.

If your Apple Valley property has an ADU or converted space of uncertain status:

Look up the zone in the Data Hub.
Ask the Permit Center whether permits exist for each unit or conversion.
Find out whether the unit could be legalized and what it would cost.
Check for related code enforcement cases.
Compare legalization cost and time with a no-repairs cash sale.
