Calabasas is the newest city in Los Angeles County, incorporated on April 5, 1991, yet the land has a long paper trail. The Leonis Adobe in Old Town dates to about 1844, and the Chamber of Commerce calls Park Moderne, settled in the 1920s by artists, craftsmen and writers, the first planned housing subdivision here. Most of the houses you see were built far later. Census ACS 2024 5-year estimates count 9,431 housing units, and the 1980s are the biggest building decade at 33.6 percent, while only 0.9 percent date from before 1950. Close to 38 percent predate 1980, which puts lead-safe rules on the table for a paid exterior repaint or a window replacement. About 60 percent of units are detached houses, 31.5 percent of occupied units are rented, and the median owner-occupied value is $1,504,500, give or take roughly $91,000. That price level is why kitchen remodels and bathroom remodels here tend to start with a long scope conversation.
Trees come before almost everything else. Section 17.32.010 of the posted municipal code says nobody may alter an oak tree or scrub oak habitat without an oak tree permit, and every other development permit has to comply with it. A director can approve small encroachments into an oak's protected zone, such as a fence line, up to 10 percent of that zone. Anything larger needs an arborist's report and goes to the Planning Commission, and a violation can bring a stop-work order and a building moratorium of up to 10 years. A new driveway or patio slab, a trench for a fence or a footing for a deck can all land inside a protected zone. We read this text on GoCodebook, a third-party mirror, because the City's own site and Municode returned a 403 error to our automated checks, so confirm every section with the City's Community Development Department.
Three canyon areas add a second gate. In the Old Topanga, Calabasas Highlands and Park Moderne overlays, the posted code calls for a Public Works encroachment permit before a building or grading permit can issue when a project adds 400 square feet or more of habitable area, grades 50 cubic yards or more, or puts in an in-ground pool. That reaches a room addition and a detached accessory unit as readily as a backyard pool. The code also limits how many of these permits can be active in an overlay at once. Beyond the overlays, any lot with a slope over 10 percent or a ridgeline falls under hillside rules in section 17.20.150, and a lot near a General Plan scenic road may need scenic corridor approval, including a minor permit for a residential fence. Neither the hillside text nor the corridor guidelines tell you what your parcel needs, so ask Planning with the address in hand.
Fire and state law shape the rest. The County's copy of CAL FIRE's map returned Very High at 95 of 99 sample points spread across the city. That is a sample, not a check of any single parcel, but it means a new roof, vents, eaves and glazing usually follow ember-resistant rules, and a final flooring or finish plan comes after those details are settled. On accessory units, lead with state law: California's housing department wrote to the City on May 4, 2026 and found its 2020 ADU ordinance out of state compliance, so local numbers may differ from what is posted or may have changed since. For work near the city line, our Los Angeles and Santa Monica guides cover those cities, while Agoura Hills, Thousand Oaks and Simi Valley keep their own codes. MDG Builders (CSLB #1040337) acts as general contractor: we draft the scope, assemble the permit package and keep the calendar, and specialty subcontractors with their own licenses carry out the field work.

- Calabasas incorporated on April 5, 1991, and Mont Calabasas was annexed in 2011.
- ACS 2024 5-year estimates count 9,431 housing units, 33.6 percent of them built in the 1980s and about 38 percent before 1980.
- Section 17.32.010 requires an oak tree permit to alter any oak, and fence-type encroachments are capped at 10 percent of a protected zone.
- Old Topanga, Calabasas Highlands and Park Moderne need a Public Works encroachment permit for 400 square feet of added living area, 50 cubic yards of grading or an in-ground pool.
- Very High fire zoning came back at 95 of 99 sampled points, a sample and not a parcel check.
- The City's site and Municode returned 403 errors, so code text comes from the GoCodebook mirror and needs City confirmation.

Calabasas questions homeowners ask before they hire
Where do I apply for a building permit in Calabasas?
Start with the City's Community Development Department, where the Building and Safety Division handles permits and Planning handles zoning, oak and scenic corridor review. We could not open the City's permit pages, so ask which handout and which code edition apply to your project, and whether Planning must review it first.
Do I need a permit to trim or remove an oak tree in Calabasas?
Yes, in most cases. The posted code requires an oak tree permit to alter any oak or scrub oak habitat, with exemptions for very small trees and verified disaster damage. Light health and clearance pruning falls under a minor permit. Removal or large encroachments need an arborist's report, so call Planning before anyone touches a branch.
What are the Old Topanga, Calabasas Highlands and Park Moderne overlays?
They are three zoning overlays where a Public Works encroachment permit comes before the building permit for larger jobs. The posted code lists 400 square feet or more of added habitable area, 50 cubic yards or more of grading and an in-ground pool. Check your parcel's overlay with the City before you commission drawings.
Is my Calabasas home in a fire hazard zone?
Probably, since Los Angeles County's copy of CAL FIRE's map returned Very High at 95 of 99 sample points across the city. That sample cannot confirm any individual lot. Look up your parcel on CAL FIRE's map and ask Building and Safety which roof, vent and window rules apply before you pick materials.
Can I build an ADU in Calabasas?
Generally yes, and state law is the safer starting point. HCD's May 4, 2026 letter found the City's 2020 ADU ordinance out of state compliance, so City rules may differ from what is posted or may have changed. Ask Planning which standards it applies today, and check the overlay if your lot is in one.
What hours can contractors work in Calabasas?
The posted code allows construction noise from 7 a.m. to 6 p.m. on weekdays and 8 a.m. to 5 p.m. on Saturday, with no work on Sundays or federal holidays unless a conditional use permit says otherwise. Confirm the current hours with the City, and tell neighbors before loud work like demolition or concrete cutting.
What does a project cost in Calabasas?
Every price on our trade pages is a sourced Los Angeles area range rather than a Calabasas quote, and only a written proposal after a site visit gives the real number. Slopes, oak protection, fire-rated materials and permit steps move the total most. Ask for the scope, the allowances and what happens if the City asks for changes.
Who does the work on a Calabasas job managed by MDG Builders?
Specialty subcontractors with their own licenses do the field work. MDG Builders, CSLB #1040337, is the contractor of record that designs, applies for permits and sequences the trades. Ask for each firm's license number and certificate of insurance, and a tenant should hand us the owner's written approval before we begin.
