ADU Setback Requirements in Agoura Hills: Essential Guidelines for Your Project

As homeowners in Agoura Hills look at adding accessory dwelling units to their property, knowing setback standards can be critical. Katz Design Builders can bring clarity and expert guidance to ensure that your project is compliant with all local regulations, especially as they pertain to setbacks. So, why are setbacks important? Essentially, setbacks refer to how close you may build your ADU to the boundaries of your property. Let’s dig deeper into some of the key questions you’ll need to ask for your ADU project in Agoura Hills.

What is the Minimum ADU Setback Requirement in Agoura Hills?

Most ADUs in Agoura Hills should have a setback of at least 4 feet on the side and rear property lines. The setbacks apply to attached and detached ADUs, except in the following exceptions:

• Side and Rear Yard Setbacks: In Agoura Hills, as in most cities, the state-mandated 4-foot setback is generally respected; however, check with your local zoning codes to determine whether this is house- or area-specific.
• Front yard setbacks: These vary more than the side and rear setbacks because they are determined by local zoning ordinances. In general, an ADU cannot be placed within the front yard setback; however, there are exceptions with garage conversions.
  

It is a reminder when designing your ADU project that local codes can change neighbourhood-specific standards. In case you are ever unsure, taking the time to discuss your project’s unique requirements with a knowledgeable contractor like Katz Design Builders will be sure to help clarify the differences.

Are the Setback Rules for Attached and Detached ADUs any Different in Agoura Hills?

Yes, depending on whether you’re building an attached ADU or a detached ADU, one of the two will have a different setback rule than the other in Agoura Hills

• Detached ADUs:  Typically, detached ADUs must be at least 4 feet from both side and rear property lines both on the side and rear.
• Attached ADUs: Attached ADU might have an advantage of setback requirements imposed on the primary residence—that is to say if the existing house is nearer to the boundary than the 4-foot requirement. In this case, an attached ADU may follow the footprints and setbacks of the primary dwelling depending on local zoning approval.

Can I Build an ADU Within My Property’s Front Yard Setback?

Typically, buildings within the front yard setback are not permitted on most properties. There are a few exceptions, however.

• Garage Conversions: If your property has a pre-existing garage with an existing footprint within the front yard setback, then you might be allowed to convert it into an ADU, but only if it stays in the same footprint.
• Variances: You can request a variance to decrease the front yard setbacks sometimes, especially if it’s an attached ADU that is roughly only 800 square feet. State laws in such areas intend to support property owners with flexibility.

Do Setback Rules Apply to a Garage Conversion ADU?

One common form of adding an ADU without dramatically changing the structure of the property is a garage conversion. If the garage is lawfully permitted and within existing setback lines, then additional setbacks are not usually necessary, provided one remains within the existing footprint. On the other hand, those erected on top of or which expand beyond the garage have a different rule set on the sides and rear side with a 4-foot setback.

Katz Design Builders can help you through this process so much more and ensure that this garage-to-ADU will be done without any hitch and according to Agoura Hills regulations.

Does ADU Size or Height Determine Setback Requirements?

Yes, the size and height of your ADU may effectually impact how much of a setback you have to provide in Agoura Hills.

• Single-story ADUs under 16 feet: these usually satisfy standard 4-foot side and rear setbacks.
• ADUs above 16 feet or with more than one story: Cities are allowed more restrictive setbacks on these ADUs if they are above 800 square feet in area or have additional height.
  

Working with experienced professionals like Katz Design Builders would ensure compliance with local codes for such complex designs.

Is there any Special Setback Rule for Small or Irregular Lots?

Smaller or more uniquely shaped lots may require additional allowances when building an ADU. The 4-foot setback along the side and rear is preserved on smaller lot sizes, but perhaps only because the specific shape of an odd lot itself is a pitfall often recognized as requiring special flexibility by the city of Agoura Hills. Those lots with irregularly shaped dimensions therefore qualify for reduced setbacks so that every homeowner has the chance to build an ADU up to 800 square feet, even considering such lot limitations.

Can Agoura Hills Set Larger ADU Setbacks Than the State’s 4-Foot Minimum?

State law provides that a minimum setback of 4 feet shall be established from the rear and side for ADUs up to 800 square feet. Cities are given discretion on what they want to do on front yard setbacks. State law precludes local government from fixing setbacks larger than the state minimum for ADUs up to 800 square feet to ensure that homeowners are placed on a level playing field.

Is there an Exception to the ADU Setback for Urban or Small Properties in Agoura Hills?

In a town or within a close-in community, the exception may be made or adjusted to work with smaller parcels of land so that an ADU can fit within odd spaces. While most towns and cities follow the 4-foot rear and side standard, Agoura Hills has proven lenient about urban or uniquely sized properties. Always best to consult a qualified ADU professional, such as Katz Design Builders, to see if this is your option.

But what is the Deal with Setback Rules when you are Adding a Second Story to an Existing Structure for that ADU?

Adding a second storey to an ADU or making an existing two-story building generally requires observance of the 4-foot side and rear setbacks. But where your proposed ADU exceeds 800 square feet or goes up to 25 feet, other setbacks may be required. A few cities do permit second-story ADUs to run in line with the setbacks of the original building when it meets the minimum 4 feet.

Can I Apply for a Setback Variance If My Lot Can’t Accommodate Standard Setbacks?

If you can’t afford to accommodate the standard setbacks on your lot, you can apply for the setback variance. While it is possible, there is no assurance that an application for setback variance shall be approved. Agoura Hills ensures that each property owner’s rights are protected, especially for those building an ADU that reaches up to 800 square feet. Katz Design Builders can walk you through variances, so the right message gets to the local authorities: you’ll be more likely to have an approved variance.
