A high-end whole-home renovation in Beverly Hills runs about $450 to $800 or more per square foot, and a new custom home about $600 to $2,000 or more by tier. Plan about 16 to 25 months for a major renovation and 30 to 48 months for a new house. Under the Beverly Hills Municipal Code, replacing more than 50 percent of the exterior walls and roof of a legally nonconforming house within five years makes it a new building that must meet current standards. For property tax, a new house is reassessed in full while the land keeps its assessed value.

A high-end whole-home renovation in Beverly Hills runs about $450 to $800 or more per square foot. A new custom home runs about $600 to $900 at a builder level of finish, $900 to $1,400 for high-end custom, and $1,400 to $2,000 or more at estate level, before demolition, site work, and soft costs.
Plan about 16 to 25 months for a major renovation and about 30 to 48 months for a new house, from the first drawings to move-in.
In Beverly Hills, replacing more than 50 percent of the exterior walls and roof of a legally nonconforming house within five years means the city treats it as a new building that has to meet current standards.
For property tax, a new house is reassessed in full at market value and only the land keeps its assessed value. In a renovation, only the work that counts as new construction is reassessed.
Renovate when the structure is sound, the ceiling heights and layout are close to what you want, and the house has something current rules would not let you build again. Rebuild when the plan, the structure, and the systems all have to change. In Beverly Hills a high-end renovation runs about $450 to $800 or more per square foot and a new custom home about $600 to $2,000 or more, and a new house takes one to two years longer.
The question usually arrives right after closing, or right before an offer: keep the house and renovate it, or take it down and build new. After more than 15 years designing high-end residential interiors in Los Angeles, alongside the architects and licensed general contractors who build them, I have seen both answers be right. What decides it is rarely taste. It is the structure, the numbers, and a handful of Beverly Hills rules that most owners learn about after the drawings have started.
Cost and timeline figures here are planning estimates, not bids. The city and tax rules are summarized from the Beverly Hills Municipal Code, the City of Beverly Hills, the California State Board of Equalization, and the Los Angeles County Assessor, all listed in the Sources. They are not legal or tax advice, so confirm how they apply to your parcel with the city and the Assessor. For the full numbers behind each path, see the Los Angeles home renovation cost guide and the Beverly Hills custom home cost guide.
Renovation is the right call when the existing house is an asset and not just a shell in the way. These are the cases where keeping it usually wins.
The structure is sound and the proportions work: If the foundation, framing, and ceiling heights are good and the layout needs adjusting, not replacing, a renovation spends the budget on what you see and use.
The house has something you could not build today: Older houses often sit closer to a property line or stand taller than current standards allow. Beverly Hills lets a legally nonconforming house be remodeled, within limits covered below, while a new house has to meet every current standard.
The architecture is worth keeping: A house by a notable architect, or one with real period character, can be worth more restored than replaced, and its age and designer can add city review before any demolition.
The scope is mostly interior: The city's design review covers the parts of a house visible from a public street. A renovation that leaves the street-facing exterior unchanged generally stays outside it.
You need to be back in sooner: A major renovation runs about 16 to 25 months from the first drawings to move-in. A new house runs about 30 to 48.
A new house costs more and takes longer, but it is the only way to change certain things. These are the cases where rebuilding usually wins.
The plan, the structure, and the systems all have to change: When the foundation needs work, the framing has to be reworked for a new layout, and every system is being replaced, the renovation is already paying for most of a new house while keeping the old one's limits.
You want ceiling height, long spans, or walls of glass: Raising ceilings and opening long spans in an existing frame means rebuilding most of it. A new structure is designed around them from the start.
You want a basement: Adding a full basement under an existing house is difficult and costly. In a new build it is part of the excavation.
The renovation would cross the 50 percent line: If the design replaces more than half of the exterior walls and roof of a legally nonconforming house, the city treats it as a new building anyway, and the whole house has to conform.
The lot is worth more than the house: When the land carries most of the value and the house is undersized for it, a new house designed to the current floor area, height, and setback standards can make better use of the site.
The table compares a high-end whole-home renovation with a new custom home on the same Beverly Hills lot. Renovation cost is the top tier from the Los Angeles renovation guide. New construction cost and timeline are the same figures used in the Beverly Hills custom home cost guide.
Construction cost per square foot: About $450 to $800 or more | About $600 to $900 at a builder level of finish, $900 to $1,400 for high-end custom, and $1,400 to $2,000 or more at estate level
Timeline, first drawings to move-in: About 16 to 25 months | About 30 to 48 months
Design review in the Central Area: Required for work visible from the public street, such as a facade remodel, window replacement, or painting | Required for every new single-family residence, as Track 1 or Track 2
What you keep: The existing structure and any legally nonconforming setbacks or height, as long as the work stays within the 50 percent rule | The land. The new house has to meet every current standard
Demolition: Improvements confined to the interior are exempt from the replacement permit rule | A demolition permit is issued only together with the building permit for the replacement house, and the city requires a bond
Risk of surprises: Higher inside the house, where framing, plumbing, wiring, and foundations are only fully seen once walls are open | Lower in the building, higher in the ground and in the review calendar
Property tax: Work that counts as new construction is reassessed. The rest of the property keeps its assessed value | The new house is reassessed in full at market value. Only the land keeps its assessed value
Ranges based on Joelle Uzyel's Beverly Hills design-build projects.
The renovation timeline assumes 3 to 5 months of design, 3 to 6 months of city review and permits, and 10 to 14 months of construction. The new construction timeline assumes 6 to 8 months of design, 6 to 10 months of city review and permits, and 18 to 30 months of construction.
Neither path is automatically cheaper. A renovation at the top of its range overlaps the lower new construction tiers, and once demolition, site work, and soft costs are added to a new house, the gap widens again. The comparison only means something when both are priced at the same finish level for the same house.
Beverly Hills is its own city, with its own planning and building departments and its own municipal code. Five of its rules bear directly on this decision. Each is summarized here from the code or the city's website, and each should be confirmed with the city for the specific parcel.
The 50 percent rule: For a legally nonconforming single-family house, the code allows a maximum of 50 percent of the combined area of the exterior walls and roof to be replaced or reconstructed in any five year period. Past that, the building is treated as newly constructed and the entire building has to conform to current development standards. A wall or roof counts as replaced when its framing is replaced. An addition is allowed if the addition itself complies.
Demolition is tied to the replacement: The city does not issue a permit to demolish a house unless the building permit for the replacement housing project is issued at the same time, and it requires a bond to guarantee safe completion and restoration of the site. Before the permit, the building has to be inspected for asbestos, the utilities notified, and the sewer capped, and demolition has to begin within 180 days of the permit.
Houses 45 years or older by a master architect: If the house is 45 years or older and its designer is on the city's list of master architects, a notice of intent to demolish has to be posted at the site at least 30 days before the permit is issued, unless the director of community development waives the requirement. Work that changes the design, material, or appearance of such a house is also subject to a 30 day holding period before permits, and designated historic properties may need a certificate of appropriateness.
Design review in the Central Area: In the Central Area, all new single-family residences, facade remodels, and additions visible from the street require design review. Projects designed by a California-licensed architect in a pure architectural style can qualify for staff-level Track 1 review. Others are Track 2 and go to the Architectural and Design Review Commission. The city states that there is no design review process in the Hillside Area.
Hillside and Trousdale limits: The Hillside Area and Trousdale Estates have their own standards. In Trousdale the maximum height of any structure is 14 feet and building is restricted to the level pad. A structure that lawfully exceeded 14 feet on October 15, 1987 may be rebuilt or remodeled, but not beyond the height or envelope it had on that date without a Trousdale R-1 permit.
Both paths work under the same construction hours. Construction that requires a city permit is not allowed between 6 p.m. and 8 a.m., on Sundays, or on the city's listed holidays, and in a residential zone it is not allowed on Saturdays, unless the city has issued an after hours construction permit. A longer project means more months on that calendar, for you and for the neighbors.
One check comes before all of these. A 90210 address in the area known as Beverly Hills Post Office is in the City of Los Angeles, where permits go through the Los Angeles Department of Building and Safety under a different set of rules. Confirm the city on the Beverly Hills zoning map or on ZIMAS, the Los Angeles zoning map, first.
In California, new construction is generally assessable, and the two paths are treated differently. The State Board of Equalization explains that when new construction is completed, the new base year value applies to the value added by the new work, and the value of the existing property is not affected.
A full rebuild is the clearest case. According to the Board of Equalization, if you tear down a house and build a new one, the entire structure is considered new construction and is reassessed at current market value, and only the assessed value of the land does not change. Leaving one wall standing makes no difference for property tax purposes.
A renovation falls on a spectrum. The Los Angeles County Assessor treats normal maintenance and repair, and replacing fixtures or finishes with items of similar quality, as not assessable. Additions, new square footage, and work that brings a property or a significant portion of it to a like-new condition, such as a house taken down to the studs, are assessable. A heavy renovation does not avoid reassessment of the new work, but the land and any part of the house left as it was keep their existing assessed value.
This is a summary of how the agencies describe the rules, not tax advice. The Assessor reviews each permit and property individually, so ask the Los Angeles County Assessor's office how a specific project would be treated before you count on a number.
Before any design work, six checks will usually settle it. Most can be done in a few weeks with an architect, a structural engineer, and a licensed general contractor.
Confirm the city and the area: Find the parcel on the Beverly Hills zoning map. The Central Area, the Hillside Area, and Trousdale Estates each have different standards, and a Beverly Hills Post Office address is in Los Angeles.
List what the house has that a new one could not: Ask the architect to compare the existing setbacks, height, and floor area with what current standards would allow on the lot.
Have the structure and systems assessed: A structural engineer and a general contractor can tell you what the foundation, framing, plumbing, and wiring need before any finish is chosen.
Measure the plan against the 50 percent rule: If the layout you want replaces more than half of the exterior walls and roof of a nonconforming house, you are designing a new house under current standards.
Check the age and the architect: If the house is 45 years or older, find out whether its designer is on the city's list of master architects before you plan a demolition date.
Price both paths at the same finish level: Compare a renovation and a new house with the same stone, millwork, and systems, and include the extra months of carrying a house you cannot live in.
If the checks point one way, the decision is made. If they split, the answer usually comes from walking the house with the people who will design and build it. If you are weighing the two for a specific house, tell the studio about the property and where you are in the decision.
Keeping one wall and calling it a remodel: For property tax, the Board of Equalization says a new house is new construction in its entirety even with one wall left standing. For zoning, the city measures how much of the exterior walls and roof is replaced.
Assuming a renovation is always cheaper: At $450 to $800 or more per square foot, a high-end renovation overlaps the cost of a new house, and hidden conditions are found after the budget is set.
Planning demolition before the new house is permitted: The demolition permit is issued together with the building permit for the replacement, so an early teardown is not an option.
Skipping the age and architect check: A 30 day notice or holding period is short, but finding out about it late moves every date behind it.
Deciding before the structure is assessed: The condition of the foundation and framing decides more than any drawing. Assess it first.
Renovating or rebuilding in Beverly Hills?
I design high-end residential interiors in Beverly Hills and across Los Angeles, working alongside the architect and a licensed general contractor on both renovations and new homes. Joelle Uzyel Interior Design takes on a limited number of full-service projects each year.
Not always. A high-end whole-home renovation runs about $450 to $800 or more per square foot, and a new custom home runs about $600 to $900 at a builder level of finish, $900 to $1,400 for high-end custom, and $1,400 to $2,000 or more at estate level, before demolition, site work, and soft costs. When the structure and every system have to be replaced, the two numbers move close together.
Under the Beverly Hills Municipal Code, a maximum of 50 percent of the combined area of the exterior walls and roof of a legally nonconforming single-family house may be replaced or reconstructed in any five year period. Beyond that, the building is treated as newly constructed and the entire building has to conform to current development standards. Confirm how it applies to your house with the city.
Generally no. The city does not issue a permit to demolish a house unless the building permit for the replacement housing project is issued at the same time, and it requires a bond. The code lists limited exemptions, such as an imminent safety hazard.
If the house is 45 years or older and its designer is on the city's list of master architects, a notice of intent to demolish has to be posted at the site at least 30 days before the permit is issued, unless the director of community development waives the requirement. Designated historic properties may also need a certificate of appropriateness.
According to the California State Board of Equalization, a new house is considered new construction in its entirety and is reassessed at current market value, while the assessed value of the land does not change. In a renovation, only the work that counts as new construction is reassessed. Ask the Los Angeles County Assessor how your project would be treated.
Plan about 30 to 48 months for a new custom home in Beverly Hills, from the first drawings to move-in, and about 16 to 25 months for a major renovation. Both include design, city review and permits, and construction.
