Apartment Renovations

Apartment Renovations near you

Apartment renovation covers three different situations that share a word. You may be a tenant improving a unit you rent, a shareholder in a housing cooperative where you own shares and a proprietary lease rather than real estate, or an owner of a unit in a multifamily building. The construction can be identical in all three; the permission problem is not, and it is the permission problem that decides whether the project happens.

What the three have in common is that you are working inside a building shared with other households. The walls and floors around your unit are rated assemblies doing a fire and sound job for the whole building, the services run through shared shafts and risers, and anything you do travels: noise during the work, dust in the corridor, water through the floor. That is why multifamily buildings have rules that a detached house does not, and why the rules are not negotiable at the crew level.

There is also a federal layer specific to rental housing. If the building went up before 1978, lead-based paint rules apply both to the landlord at lease signing and to the contractor doing the work, and those are enforceable obligations rather than best practice.

Rented, co-op or owned: three different permission problems

Work out which one you are in before you do anything else, because it determines who has to say yes and what happens to the work when you leave.

  • Renting: you are altering someone else's property, so the landlord's written consent is the starting point, and the lease usually governs whether improvements stay with the unit at the end of the tenancy.
  • Housing cooperative: you own shares in a corporation and hold a proprietary lease on the apartment, so the corporation is both your landlord and your governing body, and alteration agreements are typically formal and detailed.
  • Condominium unit in an apartment building: you own real property bounded by the declaration, and the association controls everything past that boundary.
  • Owning the whole building: you are the owner of record for permit purposes, but the code still treats the building as multifamily, which changes which code applies and what the rated assemblies have to do.
  • Subsidized or federally assisted housing: additional program rules may apply on top of everything else, and the managing agent is the place to start rather than the contractor.

Getting landlord or corporation consent in a form that protects you

Verbal permission from a landlord is worth very little when the building changes hands or the property manager changes. Ask for consent in writing and make it specific, because a vague approval to renovate the kitchen is not an approval to move the plumbing.

  • Describe the scope precisely, including what is being removed, and attach a drawing for anything that moves a wall, a fixture or a service.
  • Say explicitly who is doing the work and confirm they are licensed and insured, with the certificate of insurance attached.
  • State who pulls the permit and who holds it, since a permit is normally issued against the property and may require the owner of record to sign.
  • Record what happens at the end of the tenancy: whether improvements stay, whether the unit must be restored, and at whose cost.
  • Set out access and hours, since work in an occupied building usually has to happen inside a window the building sets.
  • Confirm how a water or power shutoff will be handled, because in a multifamily building either one affects other households.

Pre-1978 buildings: the lead disclosure rule and the RRP rule

Two separate federal rules apply to older rental housing and it is worth knowing which is whose. The first sits on the landlord. Under the federal lead disclosure requirements, sellers and landlords of most pre-1978 housing must give buyers and renters a copy of the Protect Your Family From Lead In Your Home pamphlet, disclose any known lead-based paint and lead-based paint hazards and the condition of painted surfaces, provide all available records and reports on lead-based paint and hazards, including evaluations of multi-unit buildings, and include a lead warning statement in the lease or contract. Homebuyers get a ten-day period to conduct a paint inspection or risk assessment unless the parties agree otherwise in writing, and signed disclosures are retained for three years.

The second sits on the contractor. EPA's Renovation, Repair and Painting rule applies to work in houses, apartments and child-occupied facilities built before 1978, and EPA states that anyone paid to perform work that disturbs paint in such housing must be certified, firms included. The minor repair and maintenance exemption covers activities disturbing six square feet or less of paint per room inside, or twenty square feet or less on the exterior, but EPA is explicit that window replacement and demolition of painted surfaces are always covered regardless of square footage.

In an apartment renovation the RRP rule bites more often than people expect, because old apartments are full of painted trim, painted window sashes, painted radiators and painted plaster, and removing any of it at scale is demolition of painted surfaces. Ask for the firm's EPA certification, keep a copy, and do not accept an assurance that the paint is probably lead-free in place of it.

The walls and floors around your unit are rated assemblies

In a multifamily building the partitions around a unit are not just partitions. Seattle's adopted building code, reprinting the model text used for multifamily buildings nationally, requires walls, partitions and floor-ceiling assemblies separating dwelling units and sleeping units from each other or from public or service areas to have a sound transmission class of not less than 50 where tested in accordance with ASTM E90, or a Normalized Noise Isolation Class of not less than 45 if field tested to ASTM E336.

The sentence that matters most during a renovation is the next one. The code requires penetrations or openings in those assemblies for piping, electrical devices, recessed cabinets, bathtubs, soffits, and heating, ventilating or exhaust ducts to be sealed, lined, insulated or otherwise treated to maintain the required ratings. That is the rule a crew breaks when it cuts a recessed medicine cabinet into a party wall, or runs a new duct through a demising wall and leaves the hole loose around it. The same section requires unit and guest room entrance doors from interior corridors, and interconnecting doors between separate units, to have perimeter seals and a sound transmission class rating of not less than 28.

Those assemblies are usually doing fire duty as well as sound duty, so the same penetration is normally a firestopping detail too. This is the part of an apartment renovation where hiring a contractor who works in multifamily buildings, rather than one who works in houses, shows up most clearly.

Renovating in an occupied building, around people who did not ask for it

The hardest part of most apartment renovations is not the work, it is doing it politely inside somebody else's day. Every load of material and every load of debris goes through a shared entrance, a shared corridor and usually a shared elevator, which has to be booked and protected. Noise carries structurally in ways that surprise people, so a hammer drill on a concrete slab is audible several floors away, not just next door.

Utilities are shared too, and that is where neighbors are actually affected. Isolating water for your bathroom often means shutting a riser that serves a whole line of apartments, which requires notice and a scheduled window. Electrical work may need access to a panel in a common area. Ventilation may run through a shaft shared with other units, so changing a bathroom fan is not a private decision.

Dust is the complaint that generates the most letters. Containment at the unit door, negative air where it is warranted, protection along the route to the elevator and a daily cleanup of common areas are not extras in a shared building; they are the reason the building lets renovations happen at all. Where the building is pre-1978 and paint is being disturbed, lead-safe work practices under the RRP rule overlap with all of this, so the containment is required rather than courteous.

Permits in a multifamily building, and who signs the application

The permit requirements themselves are familiar: structural alterations, plumbing, electrical and mechanical work, and anything affecting a fire-rated assembly or a means of egress. What differs is the paperwork around them. Larger multifamily buildings are regulated under the building code used for commercial and multifamily construction rather than the one-and-two-family residential code, which changes some requirements and can change who is allowed to prepare the drawings.

The application itself is the practical hurdle. Permits are issued against a property, and the owner of record for a rental building or a cooperative is the landlord or the corporation, not you. Find out who signs, what they require before signing, and how long it takes, and get that moving before your contractor's schedule depends on it. Doing work without a permit in a multifamily building is a poor bet: it surfaces at sale, at refinancing, during a neighbor's renovation, and in any insurance claim that follows a loss.

What makes apartment work cost what it costs, and how LokalMatch fits in

Three things drive the number more than the finishes do. First, access: elevator bookings, restricted hours, protection of common areas, no on-site storage and carrying everything by hand. Second, the building's construction: concrete slabs, shared risers and rated assemblies limit where plumbing and ventilation can go, and penetrations have to be treated to maintain the ratings. Third, the age of the building, because a pre-1978 apartment brings the RRP rule into the scope and older plaster, wiring and plumbing tend to produce discoveries once a wall is open.

Tell LokalMatch what the unit is and what you want done: your ZIP code, the floor, whether you rent or own, roughly how large the apartment is and which rooms are involved. Contractors who work in apartment buildings in your area receive the request and the interested ones get in touch. Contractors pay for the requests they receive and homeowners and renters use LokalMatch at no cost. LokalMatch does not perform renovations, does not quote and does not screen, rank or recommend any contractor, so checking their license, their insurance and their EPA lead certification where the building is pre-1978 is your responsibility.

Apartment Renovations: frequently asked questions

Can I renovate an apartment I rent?

Only with the landlord's permission, and you want it in writing and specific to the scope. A general approval to update the kitchen is not approval to move plumbing or take out a wall. The written consent should name who is doing the work, confirm they are licensed and insured, state who pulls the permit, and record what happens to the improvements at the end of the tenancy, including whether the unit must be restored and at whose cost.

What lead paint rules apply to an old apartment building?

Two, and they apply to different people. The federal disclosure rule requires landlords of most pre-1978 housing to give renters the Protect Your Family From Lead In Your Home pamphlet, disclose known lead-based paint and hazards and the condition of painted surfaces, provide available records and reports including evaluations of multi-unit buildings, and include a lead warning statement in the lease. Separately, EPA's Renovation, Repair and Painting rule requires firms paid to disturb paint in pre-1978 housing, including apartments, to be certified.

Does the small-job exemption cover replacing a few old windows?

No. EPA's minor repair and maintenance exemption covers activities that disturb six square feet or less of paint per room inside, or twenty square feet or less on the exterior, but EPA states that window replacement and demolition of painted surfaces are always covered regardless of square footage. In an older apartment full of painted sashes and trim, that means most of the work you would actually want done falls inside the rule.

Why can't I cut a recessed cabinet into the wall I share with next door?

Because that wall is a rated assembly. The code requires walls, partitions and floor-ceiling assemblies separating dwelling units from each other or from public or service areas to have a sound transmission class of at least 50 when tested to ASTM E90, or a Normalized Noise Isolation Class of at least 45 if field tested, and requires penetrations for piping, electrical devices, recessed cabinets, bathtubs, soffits and ducts to be sealed, lined, insulated or otherwise treated so the rating is maintained. The same wall is usually doing a fire job as well.

Who applies for the building permit if I rent?

Usually not you alone. Permits are issued against the property, and for a rental building or a cooperative the owner of record is the landlord or the corporation. Ask early whether they will sign, what they need in order to do so, and how long it takes, because it sits ahead of everything else on the schedule. Skipping the permit is a poor bet in a shared building, since unpermitted work tends to surface at sale, at refinancing, during a neighbor's renovation or in an insurance claim.

How do I keep the neighbors on side during the work?

Plan the shared parts of the project as carefully as the private ones. Book the elevator, protect the corridors and clean them daily, keep to the building's working hours, contain dust at the unit door, and give real notice before any water shutoff, since isolating a riser can affect an entire line of apartments. Where the building predates 1978 and paint is being disturbed, lead-safe work practices make that containment a requirement rather than a courtesy.

How to compare renovation contractors before you hire

  • Look for a contractor who has finished projects similar in size and type to yours, and ask to see them.
  • Get a written contract with the scope, the payment schedule, the timeline and how changes will be priced.
  • Ask who will manage the job day to day and how often you'll get updates.
  • Check that they carry liability insurance and workers' compensation coverage, and that their trades are licensed where required.
  • Compare quotes on the same scope, and ask what each one leaves out.
  • For structural changes, make sure an engineer or designer is involved where needed.

Questions to ask renovation contractors before you hire

  • Who will pull the permits, and who will be there for inspections?
  • Which parts of the job will you do yourselves, and which will go to subcontractors?
  • How do you handle change orders and unexpected problems once walls are open?
  • What is the payment schedule, and what is each payment tied to?
  • Can you show me proof of liability insurance and workers' compensation coverage?
  • What warranty do you offer on your workmanship, and is it in writing?
  • Can I speak with a few of your recent clients?

Apartment renovation permits and local rules

Some apartment renovation work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
