Sherman Oaks Homeowner Guide: Mulholland Plan, Hillsides and Permits

Last updated November 13, 2026. Reviewed by the Cash Home Buyers CA team.

Sherman Oaks is a neighborhood of the City of Los Angeles, so LADBS issues your permits and City Planning sets your zoning, but the hills above Ventura Boulevard also sit under the Mulholland Scenic Parkway Specific Plan. This guide explains which Los Angeles rules matter most in Sherman Oaks, how to read an address’s permit history, what hillside and corridor plans can add, and what to sort out before you sell. Confirm details for your own parcel with the city.

Two kinds of Sherman Oaks property

Sherman Oaks is not one regulatory environment. A flatland house south of Ventura Boulevard, a condo near the boulevard and a canyon house in the hills can each answer to different rules even though they share a name.

City Planning’s page for the Sherman Oaks community plan area lists a handful of plans that touch the area, and the one that matters most to a hillside owner is the Mulholland Scenic Parkway Specific Plan.

A flat-lot owner is more likely to deal with the base zone and the citywide rules. Knowing which group your property belongs to is the first step before you remodel, legalize work or list.

The Mulholland Scenic Parkway Specific Plan

The plan covers a corridor along Mulholland Drive. According to the plan text, the inner corridor is the right-of-way plus 500 feet outward, and the outer corridor extends to half a mile from the right-of-way.

It sets controls on land uses, grading, building height, setbacks, fences, gates, lighting and landscaping, and it created a Design Review Board.

The plan defines a project as construction, addition, alteration, conversion or change of use on a lot within the plan area, and says interior remodeling is not a project for its purposes.

It also gives special attention to prominent ridges: buildings visible from Mulholland Drive cannot be built on the top of a prominent ridge, and building within 50 vertical feet of a ridge top needs written approval from the Planning Director.

City Planning also publishes implementation guidance. It explains that later citywide hillside rules, including the Baseline Hillside Ordinance of 2011 (updated in 2017), supersede some of the plan’s older development standards, such as allowable building heights. In practice, that means a hillside owner can face the plan, the citywide hillside rules and the base zone at once. Check each before you design anything.

1. Look up the address in ZIMAS. It shows the zone, the community plan area and any specific plan or overlay.
2. Read the plan that applies. City Planning posts the Mulholland plan and its implementation guidance.
3. Ask before you design. If the lot is in the corridor, ask the planning counter whether design review is needed.
4. Then apply to LADBS. Building permits follow planning approvals.

Ventura and Cahuenga Boulevard

City Planning also lists the Ventura/Cahuenga Boulevard Specific Plan and a Sherman Oaks Streetscape Plan for the area. These mainly affect properties on and near the commercial boulevards, so a typical residential-street house will rarely be touched by them. An owner of a mixed-use building, a duplex or a lot facing the boulevard should check ZIMAS for those overlays before assuming ordinary residential rules apply.

Building permits in Sherman Oaks

Permits come from the Los Angeles Department of Building and Safety. Simple projects that need no plan review go through PermitLA, which LADBS lists as express permit projects, and everything else goes through ePlanLA. To see what has been permitted at an address, use PRISM.

Read it for permits that were opened and never finalized, work you know was done without a permit, and permits that have a completed final inspection. An open permit is a permit without a final, and buyers and their lenders ask about it.

Hillside homes often have a longer history of additions, decks, retaining walls and pools, so look at the record carefully. Our Los Angeles building permits guide explains the records in more detail.

Back units and garage conversions

The city’s ADU ordinance, No. 186,481, took effect on December 19, 2019, and City Planning’s Zoning Administrator Memo No. 143 explains how it works with state law. For a junior ADU, the single-family home must be owner-occupied, the JADU cannot be sold separately and no parking is required for it.

If a unit already exists without a permit, LADBS has a streamlined path under state law AB 2533 that may allow it to be permitted as an ADU or JADU, though it takes time and cost.

Hillside lots can add constraints such as access and fire requirements, so ask LADBS and the Fire Department what applies to your lot. Our Los Angeles zoning and ADU guide covers the details.

Code enforcement and rentals

LADBS responds to complaints about possible code violations, including construction without permits. If an inspector finds a violation, the department issues an Order to Comply to the property owner, and LADBS says the current owner is responsible for complying even if a previous owner or tenant caused it.

If you rent out a house, condo or duplex, the Los Angeles Housing Department’s Systematic Code Enforcement Program inspects rentals for building, health and safety housing codes, investigates complaints and charges an annual fee per rental unit. Our Los Angeles code enforcement guide explains Orders to Comply.

Selling in Sherman Oaks

California sellers generally must disclose known problems, including unpermitted work, and a condo seller must also deliver association documents. Hillside and canyon houses often carry deferred maintenance, older additions and open permits, which can make a conventional sale slow once a buyer’s inspection and lender appraisal begin.

If tenants live in the property, read our tenant-occupied home sale guide before you list, because a sale does not end a tenant’s rights. See also selling as-is with unpermitted work and seller closing costs.

A cash buyer can purchase a Sherman Oaks property with an open permit, an unpermitted addition or a tenant in place, and price those facts into the offer. That removes the repair, inspection and financing steps that slow a retail sale. We do not know the condition or permit record of your house until you tell us, so the offer is based on what you share.

How to sell a house in Sherman Oaks

1. Look up the address in ZIMAS and note the zone, plan area and any specific plan.
2. Pull the permit history in PRISM and gather plans, approvals and final inspection records.
3. List any work done without a permit, and any open code or rental inspection findings.
4. Request a no-obligation cash offer for the house as it stands.
5. Choose your closing date and close with no repairs or showings required.
